BACKGROUND OF THE INVENTION The present disclosure relates to adaptable clinical environments, and particularly to a modular system for constructing walls in a clinical environment. Conventional methods for constructing walls in a healthcare facility utilize timber, steel and dry wall which are more or less permanently secured to the floor and/or the ceiling of the healthcare facility. Such traditional methods of construction involve long and unreliable construction times due to the difficulties in scheduling the various craftsmen such as carpenters, painters, plumbers, electricians and the like to complete the construction work. The rooms and spaces constructed using such traditional methods are not readily reconfigurable. Any such reconfiguration requires tearing down the existing walls. Such reconfiguration is not only costly, time consuming and disruptive, but produces a lot of dirt, dust and noise. The material that is removed is generally not reusable, and has to be disposed of. Modular wall systems for dividing open spaces into cubicles and rooms are well known. Examples of such systems are disclosed in U.S. Patent Publication No. US 2002/0104271 and U.S. Patent No. 6,405,491, both of which are entitled "Modular Patient Room."

SUMMARY OF THE INVENTION The present invention comprises a system that has one or more of the following features or combinations thereof, which alone or in any combination may comprise patentable subj ect matter. A system for constructing walls may include a plurality of frame units having connection points and a plurality of patient care modules coupled to the frame units at the connection points to form a wall. The frame units may form a grid of vertically and laterally spaced apart connection points having a predetermined vertical spacing and a predetermined lateral spacing. At least some of the plurality of patient care modules may have a width substantially equal to a multiple, including one, of the predetermined lateral spacing and a height substantially equal to a multiple, including one, of the predetermined vertical spacing. Some examples of the patient care modules are a. vital signs module, a service delivery module, a bed locator module, a monitor module, a viewbox module, a sharps disposal module, a computer/keyboard module, a tube drop module, a waste management module, a light module, and a clock module. It will be understood that this list is only illustrative, and not intended to be exhaustive. Additional features, which alone or in combination with any other feature(s), such as those listed above and those listed in the appended claims, may comprise patentable subject matter and will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the embodiments as presently perceived.

Such a system 20 may, for example, be used for constructing walls in a healthcare facility such as, for example, a private patient room. Referring to Fig. 1, the patient care modules 24 illustratively include a vital signs module 200 (best shown in Fig. 3), a horizontal service delivery module 202 (best shown in Fig. 4), a vertical service delivery module 204 (best shown in Fig. 5), a bed locator module 206 (best shown in Fig. 6), a flat screen monitor module 208 (best shown in Fig. 7), a monitor module 210 with a flat screen mounted on an articulating telescopic arm (best shown in Fig. 8), a viewbox module 212 (best shown in Fig. 9), a sharps-disposal module 214 (best shown in Fig. 10), a computer and keyboard module 216 (best shown in Fig. 11), a tube drop module 218 (best shown in Fig. 12), a cabinet module 220 (best shown in Fig. 13), a waste management module 222 (best shown in Fig. 14), a light module 224 (best shown in Fig. 1) and a clock module 226 (best shown in Fig. 1). hi addition, decorative panel modules 228 may be provided for closing or covering modular spaces. It will be understood that this list is only illustrative, and not intended to.be exhaustive. It should be understood that although the illustrative wall 26 shown in Fig. 1 includes patient care modules 24, a modular wall may very well include other modules such as, for example, footwall modules, clinical wall modules, family zone modules, hygiene zone modules and the like (not shown). Some examples of family zone modules are a visitor hideaway bed module, a microwave module, a refrigerator module, a cabinet module, a drawer module, a foldout seat module, a reading lamp module, a television module, a shelving module, a wardrobe module, a decorative panel module, a whiteboard module, a tacksurface module and a mood panel module. Such family zone modules are disclosed in PCT/US2005/xxxxxx, entitled "Family Zone Modules for Hospital Walls," (attorney docket no. 7175-78001) which is assigned to the same assignee as the subject application and which is hereby incorporated by reference herein. The term "hospital equipment module" is used broadly, and includes a patient care module, a footwall module, a clinical wall module, a family zone module, a hygiene zone module, a door module, a window module, a fold-out bed module, a vital signs module, an equipment storage module, and the like. As shown in Fig. 2, the infrastructure components 22 include frame units 100 and a plurality of supporting members 102. In the illustrated embodiment, the supporting members 102 are hangers configured to be detachably coupled to the frame units 100. Each frame unit 100 includes a pair of vertical members 110 and a pair of horizontal members 112 extending between the vertical members 110 near the top and the bottom of the frame units 100 to form a generally rectangular structure with an open space or cavity 114 in the middle that extends between the front and back sides 116, 118 of the frame unit 100. Illustratively, the vertical and horizontal members 110, 112 are made from tubular members having generally rectangular cross section. The vertical members 110 of each frame unit 100 have a first plurality of connection points 120 facing the front side 116 of the frame unit 100 and a second plurality of connection points 120 facing the back side 118 of the frame unit 100. m the illustrated embodiment, the first plurality of connection points 120 is a first plurality of hanger-receiving openings 120 extending along the depth dimension and facing the front side 116 of the frame unit 100. Likewise, the second plurality of connection points 120 is a second plurality of hanger-receiving openings 120 extending along the depth dimension and facing the back side 118 of the frame unit 100. The hanger-receiving openings 120 are sized and shaped to receive the hangers 102. When inserted, the hangers 102 fit into in the hanger-receiving openings 120 in the frame units 100 so that they firmly lock in place. Illustratively, both the hangers 102 and the hanger-receiving openings 120 are generally rectangular in cross section. The hangers 102 extend generally horizontally away from the frame units 100 in a cantilevered fashion. As explained below, the lengths of the hangers 102 generally match the depth of the respective modules 24 supported by such hangers 102. The center-to-center lateral spacing 130 between the hanger-receiving openings 120 in the vertical members 110 of each frame unit 100 along the width dimension or the x-axis is fixed. Illustratively, the center-to-center lateral spacing 130 between the hanger-receiving openings 120 is about 2 feet (about 60 centimeters). The center-to-center vertical 132 spacing between the hanger-receiving openings 120 in the vertical members 110 of each frame unit 100 along the height dimension or the z-axis is also fixed. Illustratively, the center-to-center spacing 132 between the hanger-receiving openings 120 along the height dimension is about 2 feet (about 60 centimeters). Thus, the first and second plurality of hanger-receiving openings 120 are spaced apart from each other by a predetermined width 130 and a predetermined height 132 to form 2 feet-by-2 feet (about 60 centimeters by-60 centimeters) grids on the opposite sides 116, 118 of the frame units 100. Each module 24 has a width substantially equal to a discrete multiple, including one, of the predetermined width (2 feet or about 0.60 meter in the illustrated example) and a height substantially equal to a discrete multiple, including one, of the predetermined height (2 feet or about 0.60 meter in the illustrated example). In the embodiment illustrated in Fig. 2, a first plurality of modules 24 is supported by the hangers 102 on the front side 116 of the frame units 100. A second plurality of modules 24 is supported by hangers 102 on the back side 118 of the frame units 100. As shown in Fig. 15, each module 24 includes a pair of oppositely disposed guide tracks or channels 140 near the upper end of the module 24 and a pair of oppositely disposed guide tracks or channels 140 near the lower end of the module 24. The upper and lower pairs of guide tracks 140 slidably receive the corresponding hangers 102 secured to the vertical members 110 of the frame units 100. The guide tracks 140 and the hangers 102 are sized to provide a sliding fit. Suitable latches are used for securing the modules 24 to the hangers 102. The lower horizontal member 112 of each frame unit 100 has a pair of vertically extending through openings 150 for securing the frame unit 100 to the floor 152 of the healthcare facility. Likewise, the upper horizontal member 112 of each frame unit 100 has a pair of vertically extending through openings 150 for securing the frame unit 100 to the ceiling 154 of the healthcare facility where the frame unit 100 extends from the floor 152 to the ceiling 154. Any suitable fasteners 156, such as studs, pins, screws or nuts and bolts, may be used for securing the frame units 100 to the floor 152 and to the ceiling 154. In the illustrated embodiment, the frame units 100 are secured to a base board 158, instead of the floor 152, so that the modules 24 can be protected, for example, from mops, floor cleaning equipment etc. The base board 158 is, in turn, secured to the floor 152. Illustratively, the base board 158 is about 4 inches (10.16 centimeters) high. In the illustrative embodiment, each frame unit 100 is coupled to the adjoining frame units 100 on either side thereof. In addition, the frame unit 100 closest to an existing conventional wall 160 of the healthcare facility is secured thereto . To this end, the vertical members 110 of each frame unit 100 have a plurality of laterally extending through openings 162. Any suitable fasteners 164, such as studs, pins, screws or nuts and bolts, may be used for securing each frame unit 100 to the adjoining frame units 100 on the opposite sides thereof and to the adjoining existing wall 160. Utility lines 172 may be routed from the mechanical room of the healthcare facility into the patient room 28. These utility lines 172 may typically be routed through one of the floor 152, the ceiling 154 or the wall 26 of the patient room 28. The horizontal members 112 have vertically extending through slots or cutouts 170 through which utility lines 172 enter the open space or the cavity 114 defined by the frame members 110, 112. The utility lines 172 are then routed from the open space 114 to the associated modules 24. Illustratively, the utility lines 172 include data lines, gas lines, vacuum lines, AC/DC power lines, hot and cold water lines and plumbing lines. In addition, laterally extending through openings (not shown) may be formed in the vertical members 110 of the frame units 100 for passing the utility lines 172 from an open space 114 in one frame unit 100 to an open space 114 in the next adjacent frame unit 100 on either side thereof. From the open spaces 114 in the next adjacent frame units 100, the utility lines 172 are then routed to the associated modules 24. The open space 114 in the frame units 100 may be filled with sound and/or thermal insulation material. The patient care modules 24 have a width substantially equal to a discrete multiple, including one, of the predetermined lateral spacing 130 between the hanger-receiving openings 120. Illustratively, the predetermined lateral spacing 130 between the hanger-receiving openings 120 is about 2 feet (about 60 centimeters). Thus, the width of the patient care modules 24 may be about 2 feet (about 60 centimeters), 4 feet (about 120 centimeters), 6 feet (about 180 centimeters), etc. The patient care modules 24 have a height substantially equal to a discrete multiple, including one, of the predetermined vertical spacing 132 between the hanger- receiving openings 120. Illustratively, the predetermined vertical spacing 132 between the hanger-receiving openings 120 is also about 2 feet (about 60 centimeters). Thus, the height of the patient care modules 24 may be about 2 feet (about 60 centimeters), 4 feet (about 120 centimeters), 6 feet (about 180 centimeters), 8 feet (about 240 centimeters), etc. While the width and the height of the modules 24 are a discrete multiple, including one, of the predetermined lateral spacing 130 and the predetermined vertical spacing 132 between the openings 120, the depth of the modules 24 may, however, vary depending on their functionality. For example, the decorative panel modules 222 are about one inch (2.54 centimeters) deep. As previously indicated, the lengths of the hangers 102 generally match the depth of the associated modules 24 supported by said hangers 102. Thus, the length of the hangers 102 used for supporting a 1 inch (2.54 centimeters) deep decorative panel modules 228 would also be about 1 inch (2.54 centimeters). Such modular wall system 20 is disclosed in PCT/US2005/xxxxxx, entitled "Modular System for Constructing Hospital Walls" (attorney docket no. 7175-78000) which is assigned to the same assignee as this application and which is hereby incorporated by reference herein.

In response to the outputs of the vital sign measuring devices 256, 258, 260 and 262, the microcontroller 384 displays graphical and/or alphanumeric data (for example, the blood pressure, body temperature, blood oxygenation, pulse rate, and respiratory rate) on the display panel 252. The data displayed on the display panel 252 may be in the form of waveforms, bar charts, pie charts, etc., if desired. In addition, the data from the vital sign measuring devices 256, 258, 260 and 262 may be transmitted to a computer network of the healthcare facility via wired or wireless communication links. The non-invasive blood pressure measuring device 256 includes a cuff 300. The cuff 300, when not in use, is stored in a cavity or a slot 302 formed in the front wall 270. An extension cord 304 couples the blood pressure cuff 300 to a terminal 306 provided on a mounting plate 308 coupled to the front wall 270 of the housing 250. The mounting plate 308 is generally flush with the front wall 270 of the housing 250 in the illustrative example. The terminal 306 is coupled to electrical components associated with the blood pressure measuring device 256. The mounting plate 308 may form a portion of an enclosure housing electrical components of the blood pressure measuring device 256. The electrical components of the blood pressure measuring device 256 are coupled to the controller 254 as shown, for example, in Fig. 16.

The display panel 252, coupled to the controller 254, displays an analog waveform based on the output of the transducer. The thermometer 258 includes a probe 320. A holder 322 coupled to the front wall 270 releasably supports the probe 320 when the thermometer 258 is not in use. An extension cord 324 couples the probe 320 to a terminal 326 provided on a mounting plate 328 coupled to the front wall 270 of the housing 250. The mounting plate 328 is generally flush with the front wall 270 of the housing 250 in the illustrative example. The terminal 326 is coupled to electrical components associated with the thermometer 258. The mounting plate 328 may form a portion of an enclosure housing electrical components of the thermometer 258. The electrical components of the thermometer 258 are coupled to the controller 254 as shown, for example, in Fig. 16. Disposable covers (not shown) for the probe 320 are stored in the storage compartment 264. The storage compartment 264 is movable between a closed position blocking access to the probe covers and an opened position allowing access to the probe covers. The storage compartment 264 includes a handle 330. In operation, the probe 320 is inserted in a patient's mouth for measuring the temperature of the patient. The pulse oximeter 260 includes a mounting plate 340 coupled to the front wall 270 and a finger clip 342 coupled to a terminal 346 on the mounting plate 348 by an extension cord 344.

In operation, the finger clip 342 is attached to a patient's finger for measuring oxygen saturation level in the patient's blood. The cardiac monitor 262 includes a mounting plate 360 coupled to the front wall 270 and a plurality of electrodes 362 coupled to associated terminals 364 on the mounting plate 360 by respective leads 366. The mounting plate 360 is generally flush with the front wall 270 of the housing 250 in the illustrated example. The terminals 364 are coupled to electrical components associated with the cardiac monitor 262. The mounting plate 360 may form a portion of an enclosure housing electrical components of the cardiac monitor 262. The electrical components of the cardiac monitor 262 are coupled to the controller 254 as shown, for example, in Fig. 16. The electrodes 362 and the leads 366 are stored in the storage compartment 266 when the cardiac monitor 362 is not in use. The storage compartment 266 is movable between a closed position blocking access to the electrodes 362 and the leads 366 and an opened position allowing access to the electrodes 362 and the leads 366. The storage compartment 266 includes a handle 368. In operation, the electrodes 362 are attached to a patient's chest for measuring the pulse rate of the patient. In the illustrated embodiment, the cardiac monitor 262 measures a patient's respiratory rate and monitors for any signs of apnea in addition to measuring the pulse rate and the cardiac rhythm. However, when the vital signs module 200 is installed in a Med/Surge area of a healthcare facility, the vital signs module 200 may include a separate apnea monitor, hi some embodiments, the cardiac monitor 262 only measures the pulse rate. In such instances, the vital signs module 200 may include a separate respiratory rate measuring device.
