FIELD OF THE INVENTION [0002] The present invention relates generally to a method and apparatus for providing medical treatment in a warming therapy device (e.g., incubator, warmer, etc.). More particularly, the present invention relates to a method and apparatus for providing support arms which may be used in radiant heating of an infant patient disposed in the warming therapy device, as well for other purposes.

BACKGROUND OF THE INVENTION

[0003] Infant patients disposed in warming therapy devices (e.g., incubators, warmers, etc.) often require medical attention or treatment in addition to warming therapy.

For example, they may require nutrients or medicines delivered intravenously, which necessarily requires an intravenous apparatus. They may also need to be monitored, which may require an external monitor apparatus.

[0004] In addition, warming therapy devices often need to be moved throughout a hospital or health care facility, and may sometimes need to be shipped or otherwise transported to another location. The large size of warming therapy devices often makes transportation difficult. Particularly, the height at which a radiant heater can sometimes be disposed overtop a mattress of the warming therapy device can make the device awkward and cumbersome to transport.

[0005] It would be beneficial to have a warming therapy device that permits various medical monitors and devices to be coupled thereto, without the need for a separate unit. It would also be beneficial to have a warming therapy device that includes a collapsible radiant heater for easy transport. Accordingly, there is a need for a warming therapy device that

allows for easy attachment and detachment of a variety of medical devices, and is easy to store and transport.

[0026] An exemplary embodiment of the present invention comprises a warming therapy device including a patient support assembly having a front side and an opposing rear side, a left side and an opposing right side, and a patient support surface, the patient support surface defining a central portion and a perimeter. At least one multipurpose support arm may be coupled to the patient support assembly, the multipurpose support arm having a first end and an opposing second end. At least one heater may be coupled to the multipurpose support arm, which is adapted to attach to at least one medical device.

[0027] Another exemplary embodiment of the present invention comprises a warming therapy device including a patient support assembly having a front side and an opposing rear side, a left side and an opposing right side, and a patient support surface, the patient support surface defining a central portion and a perimeter. At least one multipurpose support arm having a first end and an opposing second end may be coupled to the patient support assembly adjacent the perimeter of the patient support surface. At least one extension arm having a first end and an opposing second end may be coupled to the multipurpose support arm adjacent the multipurpose support arm second end. At least one heater may be coupled to the extension arm, and the multipurpose support arm may be adapted to permit attachment of at least one medical device.

[0028] Another exemplary embodiment of the present invention comprises a warming therapy device including a patient support assembly having a front side and an opposing rear side, a left side and an opposing right side, and a patient support surface, the patient support surface defining a central portion and a perimeter. At least one multipurpose support arm having a first end and an opposing second end, may be rotatably coupled to the patient support assembly at the perimeter of the patient support surface. At least one heater may be coupled to the multipurpose support arm, which may be adapted to permit attachment of at least one medical device.

[0029] Figures 1A-5B show various exemplary embodiments of warming therapy devices 10, 1 10, 210, 310, 410, 510, 610. As described below, each exemplary embodiment may be comprised of a patient support assembly. It will be understood that the various exemplary embodiments of the multipurpose support arms may be used with virtually any patient support assembly or without a patient support assembly. For example, the patient support assembly may not be mobile (i.e., include wheels ), and may not have a platform (i.e., patient support surface) for supporting a mattress. In such an alternative embodiment, the base itself may support the mattress.

[0030] Figures I A and IB show a warming therapy device 10 according to a first exemplary embodiment. The warming therapy device 10 may be comprised of a patient support assembly 12 and at least one multipurpose support arm 32. The patient support assembly 12 has a base 14 with wheels. Coupled to the base 14 may be a support 16.

Coupled to the support 16 may be a patient support surface 18 defining a perimeter and a central portion, and at least one storage component 20, such as a tray, drawer or cabinet. The patient support surface 18 may comprise a substantially rectangular platform supporting a mattress 17 that may be generally sized for an infant patient. Even though the patient support surface 18 is shown as generally rectangular, it may be virtually any other shape such as oval, circular, square, etc. The patient support surface 18 has a front portion 22 and an opposing rear portion 24. It also has a right-side 28 and an opposing left-side 26. The front portion 22 and rear portion 24 and left side 26 and right side 28 of the patient support surface 18 correspond to front, rear, left and right sides of the support assembly 12, in general.

[0031] The warming therapy device 10 may include a single multipurpose support arm 32. The multipurpose support arm 32 may have a first end 34 and an opposing second end 36. The first end 34 of the multipurpose support arm 32 may be coupled to the patient support surface 18. However, other portions along the length of the multipurpose support arm 32 may be coupled to the patient support surface 18. For example, the multipurpose support arm 32 may be coupled to the patient support surface 18 at a half-way point. In addition, the multipurpose support arm 32 may be coupled to other parts of the patient support assembly 12 such as the base 14, support 16 or, the side of the patient support surface 18. Further, the multipurpose support arm 32 may be coupled to the patient support assembly 12 in either a fixed or removable manner.

[0032] The multipurpose support arm 32 extends upwardly from the patient support surface 18 and may be substantially perpendicular thereto as shown in Figure IA. However, the multipurpose support arm 32 may extend upwardly or downwardly and at virtually any angle with respect to the patient support surface 18 as long as it can provide effective heat to a patient (not shown) on the patient support assembly 12, as described below. The multipurpose support arm 32 may be of various shapes and configurations. For example, it may have a circular or square cross-section. Additionally, the interior may be partially or substantially completely hollow to permit the routing of wires or medical lines. Further, the overall area of the multipurpose support arms 32 may be made small as compared to the patient support surface 18 to allow better visibility of, and better access to, the patient situated on the patient support surface 18. In the exemplary embodiment shown in Figure IA, the multipurpose support arm 32 may be coupled to the patient support assembly 12 adjacent the rear portion 24 of the perimeter (or periphery) of the support surface 18. As shown in Figure 1 B, the multipurpose support arm 32 may be located about a half-way point of the rear portion 24 of the patient support surface 18.

[0033] The multipurpose support arm 32 may include at least one radiant heater 38 coupled thereto (as shown in Figs. I A and IB) for providing heat toward the mattress 17 and, therefore, toward a patient (not shown) located thereon. The radiant heater 38 may be coupled to the multipurpose support arm 32 adjacent the second end 36. However, the radiant heater 38 may be coupled at various points along the length of the multipurpose support arm 32. As shown in Figure IA, the multipurpose support arm 32 may bend 40, preferably along the 'x' axis, toward the center of the patient support surface 18. (The coordinates are defined with respect to Figure IA.) This bend 40 is located at a point adjacent the second end 36 but may be located elsewhere along the length of the multipurpose support arm 32. This bend 40 allows the radiant heater 38 head to be offset from the multipurpose support arm 32 and, thus, reduces heating of medical devices 42 that may be coupled to the multipurpose support arm 32. The multipurpose support arm 32 need not have the bend 40. In other words, it may be substantially straight from the first end 34 to the second end 36 in other exemplary embodiments.

[0034] The multipurpose support arm 32 may also be adapted to secure one or more medical devices 42. In this regard, the multipurpose support arm 32 may comprise a 25 to

100 millimeter (mm) mounting pole used to support medical devices, as are known in the art. The medical devices 42 may be coupled to the support arm 32 through known methods, or through a single or multi-piece jaw clamp or prongs. The medical devices 42 may comprise intravenous (IV) pumps, patient monitors, or the like. The medical devices 42 are shown as attached at about a center point between the first end 34 and the second end 36 of the multipurpose support arm 32. However, the medical devices 42 may be attached virtually anywhere along the length of the multipurpose support arm 32.

[0035] Figure 1C shows a warming therapy device 1 10 according to a second exemplary embodiment. The warming therapy device 1 10 may be comprised of a patient support assembly 1 12 and at least one multipurpose support arm 132. The patient support assembly 1 12 has a base 1 14 with wheels. Coupled to the base 1 14 may be a support 1 16. Coupled to the support 1 16 may be a patient support surface 1 18 defining a perimeter, a central portion and at least one storage component 120 such as a tray, drawer or cabinet. The patient support surface 1 18 may comprise a substantially rectangular platform supporting a mattress 1 17 that may be generally sized for an infant patient. Even though the patient support surface 1 18 is shown as generally rectangular, it may be virtually any other shape such as oval, circular, square, etc. The patient support surface 1 18 has a front portion 122 and an opposing rear portion 124. It also has a right-side 128 and an opposing left-side 126. The front portion 122 and rear portion 124 and left side 126 and right side 128 of the patient support surface 1 18 correspond to front, rear, left and right sides of the support assembly 1 12, in general.

[0036] The exemplary embodiment shown in Figure 1C includes a single multipurpose support arm 132. The multipurpose support arm 132 has a first end 134 and an opposing second end 136. The first end 134 of the multipurpose support arm 132 may be coupled to the patient support surface 1 18. However, other portions along the length of the multipurpose support arm 132 may be coupled to the patient support surface 1 18. For example, the multipurpose support arm 132 may be coupled to the patient support surface 1 18 at a half-way point. In addition, the multipurpose support arm 132 may be coupled to other parts of the patient support assembly 1 12 such as the base 1 14, support or, the side of the patient support surface 1 18. Further, the multipurpose support arm 132 may be coupled to the patient support assembly 112 in either a fixed or removable manner.

[0037] The multipurpose support arm 132 extends upwardly from the patient support surface 1 18 and may be substantially perpendicular thereto. However, the multipurpose support arm 132 may extend upwardly or downwardly and at virtually any angle with respect to the patient support surface 118 as long as it can provide effective heat to a patient (not shown) on the patient support assembly 1 12, as described below. The multipurpose support arm 132 may be of various shapes and configurations. For example, it may have a circular or square cross-section. Additionally, the interior may be partially or substantially completely hollow to permit the routing of wires or medical lines. Further, the overall area of the multipurpose support arm 132 may be made small as compared to the patient support surface 1 18 to allow better visibility of, and better access to, the patient situated on the patient support surface 1 18. In the exemplary embodiment shown in Figure 1C, the multipurpose support arm 132 is located adjacent the left-hand side 126 of the rear portion 124 of the perimeter (or periphery) of the patient support surface 1 18. In other words, the multipurpose support arm is positioned at the intersection of at least two sides of the support surface.

[0038] Coupled to the multipurpose support arm 132 may be at least one radiant heater 138 for providing heat toward the mattress 1 17 and, therefore, toward a patient (not shown) located thereon. The radiant heater 138 may be coupled to the multipurpose support arm 132 adjacent the second end 136. However, the radiant heater 138 may be coupled at various points along the length of the multipurpose support arm 132. The multipurpose support arm 132 may bend 140, preferably along the 'x ^* axis, toward the center of the patient support surface 1 18. This bend 140 is located at a point adjacent the second end 136 but may be located elsewhere along the length of the multipurpose support arm 132. This bend 140 allows the radiant heater 138 head to be offset from the multipurpose support arm 132 and, thus, reduces heating of medical devices 142 that may be coupled to the multipurpose support arm 132. The multipurpose support arm 132 need not have the bend 140. In other words, it may be substantially straight from the first end 134 to the second end 136 in other exemplary embodiments.

[0039] The multipurpose support arm 132 may also be adapted to secure one or more medical devices 142. In this regard, the multipurpose support arm 132 may comprise a 25 to 100 millimeter (mm) mounting pole used to support medical devices, as are known in the art.

The medical devices 142 may be coupled to the support arm 132 through known methods, or

through a single or multi-piece jaw clamp or prongs. The medical devices 142 may comprise intravenous (IV) pumps, patient monitors, or the like. The medical devices 142 are shown as attached at about a center point between the first end 134 and the second end 136 of the multipurpose support arm 132. However, the medical devices 142 may be attached virtually anywhere along the length of the multipurpose support arm 132.

[0040] Figures 2A and 2B show a warming therapy device 210 according to a third exemplary embodiment. The warming therapy device 210 may be comprised of a patient support assembly 212 and at least one multipurpose support arm 232. The patient support assembly 212 has a base 214 with wheels. Coupled to the base 214 may be a support 216. Coupled to the support 216 may be a patient support surface 218 defining a perimeter, a central portion and at least one storage component 220, such as a tray, drawer or cabinet. The patient support surface 218 may comprise a substantially rectangular platform supporting a mattress 217 that may be generally sized for an infant patient. Even though the patient support surface 218 is shown as generally rectangular, it may be virtually any other shape such as oval, circular, square, etc. The patient support surface 218 has a front portion 222 and an opposing rear portion 224. It also has a right-side 228 and an opposing left-side 226. The front portion 222 and rear portion 224 and left side 226 and right side 228 of the patient support surface 218 correspond to front, rear, left and right sides of the support assembly 212, in general. The patient support assembly may have a hood (not shown).

[0041] The exemplary embodiment shown in Figures 2A and 2B may comprise one multipurpose support arm 232. The multipurpose support arm 232 has a first end 234 and an opposing second end 236. The first end 234 of the multipurpose support arm 232 may be coupled to the patient support surface 218. However, other portions along the length of the multipurpose support arm 232 may be coupled to the patient support surface 218. For example, the multipurpose support arm 232 may be coupled to the patient support surface 218 at a half-way point. In addition, the multipurpose support arm 232 may be coupled to other parts of the patient support assembly 212 such as the base 214, support or, the side of the patient support surface 218. Further, the multipurpose support arm 232 may be coupled to the patient support assembly 212 in either a fixed or removable manner.

[0042] The multipurpose support arm 232 extends upwardly from the patient support surface 218 and may be substantially perpendicular thereto as shown in Figure 2A. However,

the multipurpose support arm 232 may extend upwardly or downwardly and at virtually any angle with respect to the patient support surface 218 as long as it can provide effective heat to a patient (not shown) on the patient support assembly 212, as described below. The multipurpose support arm 232 may be of various shapes and configurations. For example, it may have a circular or square cross-section. Additionally, the interior may be partially or substantially completely hollow to permit the routing of wires or medical lines. Further, the overall area of the multipurpose support arms 232 may be made small as compared to the patient support surface 218 to allow better visibility of, and better access to, the patient situated on the patient support surface 218.

[0043] Coupled to the multipurpose support arm 232, may be at least one radiant heater 238 for providing heat toward the mattress 217 and, therefore, toward a patient (not shown) located thereon. The radiant heater 238 may be coupled to the multipurpose support arm 232 adjacent the second end 236. However, the radiant heater 238 may be coupled at various points along the length of the multipurpose support arm 232. The multipurpose support arm 232 may bend 240, preferably along the 'x' axis, toward the center of the patient support surface 218. This bend 240 is located at a point adjacent the second end 236 but may be located elsewhere along the length of the multipurpose support arm 232. This bend 240 allows the radiant heater 238 head to be offset from the multipurpose support arm 232 and, thus, reduces heating of medical devices 242 that may be coupled to the multipurpose support arm 232. The multipurpose support arm 232 need not have the bend 240. In other words, it may be substantially straight from the first end 234 to the second end 236 in other exemplary embodiments.

[0044] The multipurpose support arm 232 may also be adapted to secure one or more medical devices 242. In this regard, the multipurpose support arm 232 may comprise a 25 to 100 millimeter (mm) mounting pole used to support medical devices, as are known in the art. The medical devices 242 may be coupled to the support arm 232 through known methods, or through a single or multi-piece jaw clamp or prongs. The medical devices 242 may comprise intravenous (IV) pumps, patient monitors, or the like. The medical devices 242 are shown as attached at about a center point between the first end 234 and the second end 236 of the multipurpose support arm 232. However, the medical devices 242 may be attached virtually anywhere along the length of the multipurpose support arm 232.

[0045] In the exemplary embodiment shown in Figures 2A and 2B, the multipurpose support arm 232 may be coupled to the patient support surface 218 or patient support assembly 212 adjacent the left-hand side 226 of the rear portion 224 of the perimeter (or periphery). In other words, the multipurpose support arm may be positioned at the intersection of at least two sides of the support surface. However, the multipurpose support arm 232 may be coupled to the patient support assembly 212 at the right-hand side 228 or center of the rear portion 224. The multipurpose support arm 232 may be curved 244 along its length. The curve 244 extends along the 'z' direction as opposed to the bend 240, which bends along the 'x ^' direction. Preferably, the multipurpose support arm 232 is curved 244 toward the center of the patient support surface 218 or mattress 217 and terminates at a central location above the patient support assembly 212. Preferably, the multipurpose support arm 232 is curved adjacent the second end 236, however, it may be curved at other points along its length.

[0046] Figures 3A-3B show a fourth exemplary embodiment of a warming therapy device 310. The warming therapy device 310 may be comprised of a patient support assembly 312 and at least one multipurpose support arm 332. The patient support assembly

312 has a base 314 with wheels. Coupled to the base 314 may be a support 316. Coupled to the support 316 may be a patient support surface 318 defining a perimeter, a central portion and at least one storage component 320, such as a tray, drawer or cabinet. The patient support surface 318 may comprise a substantially rectangular platform supporting a mattress

317 that may be generally sized for an infant patient. Even though the patient support surface

318 is shown as generally rectangular, it may be virtually any other shape such as oval, circular, square, etc. The patient support surface 3 18 has a front portion 322 and an opposing rear portion 324. It also has a right-side 328 and an opposing left-side 326. The front portion 322 and rear portion 324 and left side 326 and right side 328 of the patient support surface 318 correspond to front, rear, left and right sides of the support assembly 312, in general. The patient support assembly may have a hood.

[0047] The exemplary embodiment shown in Figures 3A-3B may comprise two support arms 332. Each has a first end 334 and an opposing second end 336. The first ends 334 of the multipurpose support arms 332 may be coupled to the patient support surface 318.

However, other portions along the length of the multipurpose support arms 332 may be

coupled to the patient support surface 318. For example, the multipurpose support arms 332 may be coupled to the patient support surface 318 at a half-way point. Preferably, the two multipurpose support arms 332 are disposed to each side 326, 328 of the patient support surface 318, at the rear portion 324 of the patient support surface 318 at the perimeter (or periphery). In other words, the multipurpose support arms are positioned at the intersection of at least two sides of the support surface. In addition, the multipurpose support arms 332 may be coupled to other parts of the patient support assembly 312 such as the base 314, support or, the side of the patient support surface 318. Further, the multipurpose support arms 332 may be coupled to the patient support assembly 312 in either a fixed or removable manner.

[0048] The multipurpose support arms 332 extend upwardly from the patient support surface 318 and may be substantially perpendicular thereto as shown in Figure 3A. However, the multipurpose support arms 332 may extend upwardly or downwardly and at virtually any angle with respect to the patient support surface 318 as long as they provide effective heat to a patient (not shown) on the patient support assembly 312, as described below. The multipurpose support arms 332 may be of various shapes and configurations. For example, they may have a circular or square cross-section. Additionally, the interior may be partially or substantially completely hollow to permit the routing of wires or medical lines. Further, the overall area of the multipurpose support arms 332 may be made small as compared to the patient support surface 318 to allow better visibility of, and better access to, the patient situated on the patient support surface 318.

[0049] Coupled to the multipurpose support arms 332, may be at least one radiant heater 338 for providing heat toward the mattress 317 and, therefore, toward a patient (not shown) located thereon. The radiant heater 338 may be coupled to the multipurpose support arms 332 adjacent the second end 336. However, the radiant heater 338 may be coupled at various points along the length of the multipurpose support arms 332. The multipurpose support arms 332 may bend 340, preferably along the 'x' axis, toward the center of the patient support surface 318. This bend 340 is located at a point adjacent the second end 336 but may be located elsewhere along the length of the multipurpose support arms 332. This bend 340 allows the radiant heater 338 head to be offset from the multipurpose support arms 332 and, thus, reduces heating of medical devices 342 that may be coupled to the

multipurpose support arms 332. The multipurpose support arms 332 need not have the bend 340. In other words, they may be substantially straight from the first end 334 to the second end 336 in other exemplary embodiments.

[0050] The multipurpose support arms 332 may also be adapted to secure one or more medical devices 342. In this regard, the multipurpose support arm 332 may each comprise a

25 to 100 millimeter (mm) mounting pole used to support medical devices, as are known in the art. The medical devices 342 may be coupled to the support arm(s) 332 through known methods, or through a single or multi-piece jaw clamp or prongs. The medical devices 342 may comprise intravenous (IV) pumps, patient monitors, or the like. The medical devices 342 are shown as attached at about a center point between the first end 334 and the second end 336 of the multipurpose support arms 332. However, the medical devices 342 may be attached virtually anywhere along the length of the multipurpose support arms 332.

[0051] Figures 3C-3E show a warming therapy device 410 according to a fifth exemplary embodiment. The patient support assembly 412 has a base 414 with wheels. Coupled to the base 414 may be a support 416. Coupled to the support 416 may be a patient support surface 418 defining a perimeter, a central portion and at least one storage component 420, such as a tray, drawer or cabinet. The patient support surface 418 may comprise a substantially rectangular platform supporting a mattress 417 that may be generally sized for an infant patient. Even though the patient support surface 418 is shown as generally rectangular, it may be virtually any other shape such as oval, circular, square, etc. The patient support surface 418 has a front portion 422 and an opposite rear portion 424. It also has a right-side 428 and an opposing left-side 426. The front portion 422 and rear portion 424 and left side 426 and right side 428 of the patient support surface 418 correspond to front, rear, left and right sides of the support assembly 412, in general. The patient support assembly may have a hood 430.

[0052] The exemplary embodiment shown in Figure 3C-3E may have two (2) multipurpose support arms 432. The multipurpose support arms 432 have a first end 434 and an opposing second end 436. The first ends 434 of the multipurpose support arm 432 may be coupled to the patient support surface 418. However, other portions along the length of the multipurpose support arms 432 may be coupled to the patient support surface 418. For example, the multipurpose support arms 432 may be coupled to the patient support surface

418 at a half-way point. In addition, the multipurpose support arms 432 may be coupled to other parts of the patient support assembly 412 such as the base 414, support or, the side of the patient support surface 418. Further, the multipurpose support arms 432 may be coupled to the patient support assembly 412 in either a fixed or removable manner.

[0053] The multipurpose support arms 432 extend upwardly from the patient support surface 418 and may be substantially perpendicular thereto in the position shown in Figure 3C. However, the multipurpose support arms 432 may extend upwardly or downwardly and at virtually any angle with respect to the patient support surface 418 as long as they can provide effective heat to a patient (not shown) on the patient support assembly 412, as described below. The multipurpose support arms 432 may be of various shapes and configurations. For example, they may have a circular or square cross-section. Additionally, their interior may be partially or substantially completely hollow to permit the routing of wires or medical lines. Further, the overall area of the multipurpose support arms 432 may be made small as compared to the patient support surface 418 to allow better visibility of, and better access to, the patient situated on the patient support surface 418.

[0054] Coupled to the multipurpose support arms 432, may be at least one radiant heater 438 for providing heat toward the mattress 417 and, therefore, toward a patient (not shown) located thereon. The radiant heater 438 may be coupled to the multipurpose support arms 432 adjacent the second ends 436. However, the radiant heater 438 may be coupled at various points along the length of the multipurpose support arms 432. The multipurpose support arms 432 may bend 440, preferably along the 'x' axis. This bend 440 is located at a point adjacent the second end 436 but may be located elsewhere along the length of the multipuφose support arm 432. This bend 440 allows the radiant heater 438 head to be offset from the multipurpose support arms 432 and, thus, reduces heating of medical devices (not shown) that may be coupled to the multipurpose support arms 432. The multipuφose support arms 432 need not have the bend 440. In other words, they may be substantially straight from the first end 434 to the second end 436 in other exemplary embodiments.

[0055] The multipuφose support arms 432 may also be adapted to secure one or more medical devices. In this regard, the multipuφose support arm 432 may each comprise a 25 to 100 millimeter (mm) mounting pole used to support medical devices, as are known in the art.

The medical devices 442 may be coupled to the support arm 432 through known methods, or

through a single or multi-piece jaw clamp or prongs. The medical devices may comprise intravenous (IV) pumps, patient monitors, or the like. The medical devices are shown as attached at about a center point between the first end 434 and the second end 436 of the multipurpose support arm 432. However, the medical devices may be attached virtually anywhere along the length of the multipurpose support arm 432.

[0056] In the exemplary embodiment shown in Figures 3C-3E, the first ends 434 of both multipurpose support arms 432 are coupled to the patient support assembly 412 adjacent the rear portion 424 at the perimeter (or periphery). In other words, the multipurpose support arms are positioned near or at the intersection of at least two sides of the support surface. One multipurpose support arm 432 may be coupled to the left-hand side 426 of the patient support surface 418 and one multipurpose support arm 432 may be coupled to the right-hand side 428 of the patient support surface 418. Coupled to each multipurpose support arm 432, adjacent the second end 436, may be the radiant heater 438. Each multipurpose support arm 432 may have its own heater 438. However, as shown in Figures 3C-3E, one radiant heater 438 may be coupled to both multipurpose support arms 432.

[0057] As shown in Figure 3C, the multipurpose support arms 432 may be rotatably coupled to the patient support assembly 412. In particular, the multipurpose support arms 432 may be coupled via rotation means 446 such as a pin or bolt to a rotation socket. Virtually any known rotation means 446 may be used to attach the multipurpose support arms 432 to the patient support assembly or patient support surface 418. For example, bolts, screws or other equivalent means may be used if they permit the multipurpose support arms 432 to rotate about the patient support assembly. The multipurpose support arms 432 may also have means for extending and retracting 448 the same (i.e., telescoping), such as a threaded collar which may be loosened to allow telescoping, and tightened to prevent it. As such, one portion of the multipurpose support arms 432 may be slidably disposed with another. The multipurpose support arms 432 may include means for locking the slidable portion in position. Figure 3C shows a 'standard' position of the warming therapy device 410, which is the position the warming therapy device 410 is typically in when in use with a patient thereon. In this position, the multipurpose support arms 432 are at an approximately 90 degree angle with respect to the patient support surface 418.

[0058] As shown in Figure 3D, the multipurpose support arms 432 may be rotated from the standard position. Figure 3D shows the multipurpose support arms 432 rotated toward the patient support surface 418 until the multipurpose support arms 432 are substantially parallel with respect to the patient support surface 418 and the second end 436 is adjacent the front portion 422 of the patient support surface 418. This is the 'partially collapsed' position. As will be noted, the overall height of the warming therapy device 410 is significantly decreased in the 'partially collapsed' position as compared to the standard position. This makes the warming therapy device 410 more compact allowing for easy storing, shipping, etc. The multipurpose support arms 432, patient support surface 418, rotation socket or pin, patient support assembly or heater 438 may also include means for stopping the multipurpose support arms 432 at a point of rotation. This would allow for the multipurpose support arms 432 to be positioned at virtually any angle with respect to the patient support surface 4] 8 or patient support assembly 412.

[0059] As shown in Figure 3E, the warming therapy device 410 may be further collapsed by collapsing the multipurpose support arms 432 via the telescoping means 448. In this regard, the multipurpose support arms 432 are moved toward the front portion 422 of the patient support surface 418 or patient support assembly 412. This is the 'completely collapsed' position. In this position, the radiant heater 438 may be in close proximity (or even contact) with the patient support assembly 412. The overall height and width of the warming therapy device 410 is significantly decreased in the 'completely collapsed' position thus allowing for easy packaging and shipping of the warming therapy device 410. For example, a much smaller packing box can be used to ship the warming therapy device 410 in the 'completely collapsed' position, as opposed to the 'standard' position. Thus, the warming therapy device 410 may be manufactured, tested, and then shipped directly to the customer as is, in the 'completely collapsed' position. When the customer receives the warming therapy device 410, they need only retract the telescoping arms, and rotate them ninety degrees (90°) to achieve the 'standard' operable position. It is noted that although collapsible support arms 432 are shown in only the exemplary embodiment of Figures 3C-3E, virtually any embodiment of the warming therapy device 410 may have collapsible multipurpose support arm(s) that operate as described above. Preferably, if one multipurpose support arm 432 is collapsible and being used with a patient support assembly having a hood 430, the multipurpose support arm 432 would be located proximate to the left 426 or right-hand side

428 of the patient support assembly so as not to interfere with the hood 430 when folding toward the patient support surface 418. In addition, medical devices 442 attached to the multipurpose support arms 432 may be removed before collapsing the multipurpose support arms 432.

[0060] Figures 4A and 4B show a sixth exemplary embodiment of a warming therapy device 510. The warming therapy device 510 may be comprised of a patient support assembly 512 and at least one multipurpose support arm 532. The patient support assembly 512 has a base 514 with wheels. Coupled to the base 514 may be a support 516. Coupled to the support 516 may be a patient support surface 518 defining a perimeter, a central portion and at least one storage component 520, such as a tray, drawer or cabinet. The patient support surface 518 may comprise a substantially rectangular platform supporting a mattress

517 that may be generally sized for an infant patient. Even though the patient support surface

518 is shown as generally rectangular, it may be virtually any other shape such as oval, circular, square, etc. The patient support surface 518 has a front portion 522 and an opposing rear portion 524. It also has a right-side 528 and an opposing left-side 526. The front portion 522 and rear portion 524 and left side 526 and right side 528 of the patient support surface 518 correspond to front, rear, left and right sides of the support assembly 512, in general. The patient support assembly may have a hood.

[0061] The exemplary embodiment shown in Figures 4A and 4B comprises one multipurpose support arm 532. The multipurpose support arm 532 has a first end 534 and an opposing second end 536. The first end 534 of the multipurpose support arm 532 may be coupled to the patient support surface 518. However, other portions along the length of the multipurpose support arm 532 may be coupled to the patient support surface 518. For example, the multipurpose support arm 532 may be coupled to the patient support surface 518 at a half-way point. In addition, the multipurpose support arm 532 may be coupled to other parts of the patient support assembly 512 such as the base 514, support or, the side of the patient support surface 518. Further, the multipurpose support arm 532 may be coupled to the patient support assembly 512 in either a fixed or removable manner.

[0062] The multipurpose support arm 532 extends upwardly from the patient support surface 518 and may be substantially perpendicular thereto as shown in Figure 4A. However, the multipurpose support arm 532 may extend upwardly or downwardly and at virtually any

angle with respect to the patient support surface 518 as long as it can provide effective heat to a patient (not shown) on the patient support assembly 512, as described below. The multipurpose support arm 532 may be of various shapes and configurations. For example, it may have a circular or square cross-section. Additionally, the interior may be partially or substantially completely hollow to permit the routing of wires or medical lines. Further, the overall area of the multipurpose support arms 532 may be made small as compared to the patient support surface 518 to allow better visibility of, and better access to, the patient situated on the patient support surface 518.

[0063] The multipurpose support arm 532 may also be adapted to secure one or more medical devices 542. In this regard, the multipurpose support arm 532 may comprise a 25 to

100 millimeter (mm) mounting pole used to support medical devices, as are known in the art.

The medical devices 542 may be coupled to the support arm 532 through known methods, or through a single or multi-piece jaw clamp or prongs. The medical devices 542 may comprise intravenous (IV) pumps, patient monitors, or the like. The medical devices 542 are shown as attached at about a center point between the first end 534 and the second end 536 of the multipurpose support arm 532. However, the medical devices 542 may be attached virtually anywhere along the length of the multipurpose support arm 532.

[0064] In the exemplary embodiment shown in Figure 4B, the multipurpose support arm 532 may be located about a half-way point (along the z-axis) along the rear portion 524 at the perimeter (or periphery). Coupled to the multipurpose support arm 532 may be at least one extension arm 550. The extension arm 550 may be coupled to the multipurpose support arm 532 adjacent the second end 536 of the multipurpose support arm 532 but may be coupled elsewhere. The extension arm 550 has a first end 552 and an opposing second end 554. In the exemplary embodiment shown in Figures 4A and 4B, the multipurpose support arm 532 may be coupled to the extension arm 550 at a point about half-way between the first end 552 and the second end 554 of the extension arm 550 forming a T-shape. The T-shape allows two radiant heaters 538 to be coupled to the same multipurpose support arm 532 at locations on opposing sides of the patient support assembly 512.

[0065] A heater 538 may be located at the extension arm 550 first end 552 and another heater 538 may be located at the extension arm 550 second end 554. The heaters may be radiant heaters 538 for providing heat toward the mattress 517 and, therefore, toward

a patient (not shown) located thereon. The multipurpose support arm 532 may bend 540, preferably along the 'x' axis, toward the center of the patient support surface 518. This bend 540 is located at a point adjacent the second end 536 but may be located elsewhere along the length of the multipurpose support arm 532. This bend 540 allows the radiant heater 538 head to be offset from the multipurpose support arm 532 and, thus, reduces heating of medical devices 542 that may be coupled to the multipurpose support arm 532. The multipurpose support arm 532 need not have the bend 540. In other words, it may be substantially straight from the first end 534 to the second end 536 in other exemplary embodiments. In other exemplary embodiments, one heater 538 may span the length of the extension arm 550.

[0066] Figures 5 A and 5B show a warming therapy device 610 according to a seventh exemplary embodiment. The warming therapy device 610 may be comprised of a patient support assembly 612 and at least one multipurpose support arm 632. The patient support assembly 612 has a base 614 with wheels. Coupled to the base 614 may be a support 616. Coupled to the support 616 may be a patient support surface 618 defining a perimeter, a central portion and at least one storage component 620, such as a tray, drawer or cabinet. The patient support surface 618 may comprise a substantially rectangular platform supporting a mattress 617 that may be generally sized for an infant patient. Even though the patient support surface 618 is shown as generally rectangular, it may be virtually any other shape such as oval, circular, square, etc. The patient support surface 618 has a front portion 622 and an opposing rear portion 624. It also has a right-side 628 and an opposing left-side 626. The front portion 622 and rear portion 624 and left side 626 and right side 628 of the patient support surface 618 correspond to front, rear, left and right sides of the support assembly 612, in general. The patient support assembly may have a hood 630.

[0067] The exemplary embodiment shown in Figures 5A and 5B comprises one multipurpose support arm 632. The multipurpose support arm 632 has a first end 634 and an opposing second end 636. The first end 634 of the multipurpose support arm 632 may be coupled to the patient support surface 618. However, other portions along the length of the multipurpose support arm 632 may be coupled to the patient support surface 618. For example, the multipurpose support arm 632 may be coupled to the patient support surface 618 at a half-way point. In addition, the multipurpose support arm 632 may be coupled to

other parts of the patient support assembly 612 such as the base 614, support or, the side of the patient support surface 618. Further, the multipurpose support arm 632 may be coupled to the patient support assembly 612 in either a fixed or removable manner.

[0068] The multipurpose support arm 632 extends upwardly from the patient support surface 618 and may be substantially perpendicular thereto as shown in Figure 5 A. However, the multipurpose support arm 632 may extend upwardly or downwardly and at virtually any angle with respect to the patient support surface 618 as long as it can provide effective heat to a patient (not shown) on the patient support assembly 612, as described below. The multipurpose support arm 632 may be of various shapes and configurations. For example, it may have a circular or square cross-section. Additionally, the interior may be partially or substantially completely hollow to permit the routing of wires or medical lines. Further, the overall area of the multipurpose support arms 632 may be made small as compared to the patient support surface 618 to allow better visibility of, and better access to, the patient situated on the patient support surface 618.

[0069] The multipurpose support arm 632 may also be adapted to secure one or more medical devices 642. In this regard, the multipurpose support arm 632 may comprise a 25 to 100 millimeter (mm) mounting pole used to support medical devices, as are known in the art. The medical devices 642 may be coupled to the support arm 632 through known methods, or through a single or multi-piece jaw clamp or prongs. The medical devices 642 may comprise intravenous (IV) pumps, patient monitors, or the like. The medical devices 642 are shown as attached at about a center point between the first end 634 and the second end 636 of the multipurpose support arm 632. However, the medical devices 642 may be attached virtually anywhere along the length of the multipurpose support arm 632.

[0070] In the exemplary embodiment shown in Figure 5B, the multipurpose support arm 632 may be located at a rear end 624, left-hand side 626 of the perimeter (or periphery) of the patient support surface 618. In other words, the multipurpose support arm is positioned at the intersection of at least two sides of the support surface. Coupled to the multipurpose support arm 632 may be at least one extension arm 650. The extension arm 650 may be coupled to the multipurpose support arm 632 adjacent the second end 636 of the multipurpose support arm 632 but may be coupled elsewhere. The extension arm 650 has a first end 652 and an opposing second end 654. The multipurpose support arm 632 is coupled

to the extension arm 650 adjacent the first end 652 of the extension arm 650. Thus, the multipurpose support arm 632 is substantially L-shaped. The L-shape of the multipurpose support arm 632 allows two radiant heaters 638 to be coupled to the same multipurpose support arm 632 at locations on opposing sides of the patient support assembly 612.

[0071] A heater 638 may be located at the extension arm 650 first end 652 and another heater 638 may be located at the extension arm 650 second end 654. The heaters may be radiant heaters 638 for providing heat toward the mattress 617 and, therefore, toward a patient (not shown) located thereon. The multipurpose support arm 632 may bend 640, preferably along the 'x' axis, toward the center of the patient support surface 618. This bend 640 is located at a point adjacent the second end 636 but may be located elsewhere along the length of the multipurpose support arm 632. This bend 640 allows the radiant heater 638 head to be offset from the multipurpose support arm 632 and, thus, reduces heating of medical devices 642 that may be coupled to the multipurpose support arm 632. The multipuφose support arm 632 need not have the bend 640. In other words, it may be substantially straight from the first end 634 to the second end 636 in other exemplary embodiments. In other exemplary embodiments, one heater 638 may span the length of the extension arm 650.

[0072] The exemplary embodiments using dual radiant heaters (Figures 3-6), provide additional redundancy, so if one heater fails, the other can compensate, by either activating (in the case where only one heater at a time is used) or providing increased heating (to make up for the heat lost from the failure of the first heater). Dual heaters also permit the caregiver to temporarily (or permanently) switch off one of the heaters, so he or she can approach and examine the patient disposed on the mattress without being subjected to excess heat. For example, the caregiver may deactivate the heater on the left hand side of the mattress so that he or she can approach the mattress from that side, and perform any examinations, observations or medical procedures, which are required.

[0073] In all of the exemplary embodiments, the radiant heater may comprise an infrared (IR) heating device. Although a radiant heater is typically used in 'open care' embodiments (i.e., where a patient disposed on the mattress is warmed directly by the IR heater), IR heating also has benefits in 'closed care' environments (where a hood is disposed over the mattress and warming air is circulated within the hood). For example, IR heating in

'closed care' environments reduces condensation on the hood. When a hood is placed over the mattress and warm air is circulated within the hood in the area around the mattress, condensation may build up on the walls of the hood due to the temperature difference between the external air and the heated air inside the hood. Typically, in 'closed care' environments, the air inside the hood is between eighty-five to ninety-five degrees (85-95 ⁰ F), and the external air is around sixty-five to seventy-five degrees (65-75 ⁰ F). This temperature difference often creates condensation on the walls of the hood, making it difficult for the caregiver to view the infant patient. IR heating devices may be used to increase the external temperature of the hood, and thus reduce or eliminate such condensation (i.e., they dry up the condensation).

[0074] Any of the aforementioned warming therapy devices may include a hood. The hood provides the 'closed care' environment where heated air is circulated within the hood to the patient (not shown) disposed on the mattress. When condensation builds up on the walls of the hood, the IR radiant heaters may be activated to reduce or eliminate the condensation on the hood, and thus allow the caregiver to see inside the hood (to the patient disposed on the mattress) more clearly. A hood may be used with any exemplary embodiment shown. For example, using a hood with the exemplary embodiment of the warming therapy device shown in Figures 4A and 4B, has been found to work well because the dual-head design permits the reduction of condensation on both side walls of the hood.

[0075] All of the exemplary embodiments allow quick and easy attachment of various medical devices to the warming therapy device and reduce the overall complexity of the structure. For example, existing incubators typically do not provide for the attachment of other medical devices. The multipurpose support arms provide support for radiant heating devices and also permit the attachment of one or more medical devices, such as intravenous (IV) pumps, patient monitors, or the like.

[0076] Although the invention has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly to include other variants and exemplary embodiments of the invention, which may be made by those skilled in the art without departing from the scope and range of equivalents of the invention. This disclosure is intended to cover any adaptations or variations of the

exemplary embodiments discussed herein. An apparatus as described above with reference to the foregoing description and appended drawings is hereby claimed.
