Description:
NASAL-PRONG AND NASAL-MASK CANNULA AND GAS TANK SUPPLY SYSTEM

BACKGROUND OF THE INVENTION

[0001 ] This application relates generally to the field of cannulas used with nasal prongs or nasal masks, regulators, and gas tanks used to deliver oxygen or other gases from a tank supply and regulator to a patient through the nostrils, and more particularly relates to improving the use of the cannula and tank system.

[0002] Nasal prong cannulas for supplying oxygen or other gases to patients are well known in the medical field and are typically comprised of an elongated tubular main body having a pair of tubular nasal or nostril prongs extending substantially perpendicularly from the main body, the combination often being referred to as a nose piece. Patients with more severe symptoms of continuous positive airway pressure (“CPAP”) or bilevel positive airway pressure (BiPAP or BPAP) may need to wear a mask that covers the nose and mouth to allow for more oxygen flow than with their cannula tubing. The air pressure keeps the throat muscles from collapsing and reducing obstructions by acting as a splint. Both CPAP and BiPAP machines allow patients to breathe easily and regularly throughout the night. The tubular main body is open on both ends and connects with a regulator attached to a gas supply tank or cannula tubing such that gas, for example oxygen, may be delivered by a compressed-gas tank, a compressor, or a pump, through a regulator connected to one or both gas supply tubes into the tubular main body of the nasal cannula and then through the nostril prongs to be dispelled into the nasal passages of the patient.

[0003] To secure the device to the patient, the nose piece of the device is positioned below the nose with the nasal prongs inserted within the nostrils of the patient's nose. Below the nose, the tube separates into two tubes which wrap around the patient’s ears and descending under the chin at which point the two tubes join to become one gas supply tube, joined together by a sliding collar such that the tubes can be tightened to maintain a snug fit of the nasal prongs to the patient’s face. A patient with a nasal mask, instead of nasal prongs, will position the mask over the bridge of their nose and under their chin.

[0004] There are problems associated with the use of cannulas, regulators, and the supply tank. Crimping of the cannula can occur, for example, at the location where the cannula is connected to the regulator attached to an oxygen tank, concentrator, or other oxygen supply device, which restricts the flow of oxygen. In addition, the cannula tubing must be of sufficient length to allow the patient to move away from the oxygen tank or supply, but the additional tubing length can be cumbersome or get in the way of the patient's daily activities. In addition, when placed over the ears, the tubing can impose too much tension or weight on the patient’s ears so as to cause discomfort. Typically, a regulator is attached to the oxygen supply. With most oxygen supplies, the regulator includes no warning device to alert the patient that the oxygen levels are nearing the critical level of zero liters or when the flow rate of gas is below the prescribed flow rate. Oxygen saturation (Sa02) is a measurement of the percentage of how much hemoglobin is saturated with oxygen. Oxygen is transported in the blood in two ways: oxygen dissolved in blood plasma (rq2) and oxygen bound to hemoglobin (SaOz). Patients thus can be placed in a detrimental medical position of having too low SaOi saturation levels and not being aware that they need to replace their oxygen supply tank or battery to continue proper oxygen flow that is necessary for proper physiological Sa(½ levels. In addition, with most oxygen supplies the regulator does not include a timing device or mechanism to alert the patient that it is time to replace the cannula so as to avoid the deleterious effects of the buildup of bacteria or the deterioration or hardening of the tubing.

[0005] U.S. Patent No. 10,034,995 which is incorporated by reference, discloses retractable cannula tube used for CPAP.

[0006] Nasal prong and nasal mask cannulas and their associated regulators and oxygen tanks all look virtually the same. In addition, patients would like to stylize and personalize their equipment which would also differentiate it from the equipment of others.

[0007] The gas supply system typically comprises a metal tank filled with gas, such as oxygen, a regulator connected to the tank indicating the flow rate of the gas, and a cannula with nasal prongs or nasal mask connected to the regulator.

[0008] Patients typically use several metal gas tanks per day and metal tanks can be difficult to handle and carry and create a hazardous situation when multiple metal gas tanks are stacked together, metal to metal, for storage or transport. The awkward style and bulkincss of the tanks is a barrier for patients to accept their use and comply with their medically prescribed oxygen needs.

A SUMMARY OF THE INVENTION

[0009] It is an object of the invention to provide a system to improve the structure and design of cannulas, CPAP and CBiAP and the gas supply system to which they are connected. [00010] Another object of the invention is to enhance the cannula tubing at the port base of the regulator attached to an oxygen source to minimize“crimping” and diminished oxygen delivery.

[0001 1 ] Another object of the invention is to design a cannula that will expand in length as needed and shorten as needed without loss of pressure (PSl) of oxygen from start point of oxygen source to the patient

[00012] Another object of the invention is to provide a device, such as a clasp, clip, or hook in connection with the cannula which can be attached to the patient's clothing so as to relieve the tension or weight placed on the ears by the cannula and to keep the cannula close to the patient's body.

[00013] Another object of the invention is to provide a storage means for holding extra cannula length without crimping the cannula for portable oxygen cloth cany cases, wheelchair oxygen cloth carry cases, and oxygen constant/pulse flow tanks. For example, a slip-on“sock” or“cap” or“glove" or“sleeve” may be fitted over or around the oxygen tank which sock, cap or glove may include a Velcro® storage means made by Velcro out of the United Kingdom or a similar functioning product, which is a hook-and-!oop fastener, flap, clasp, hook, or other fastening means to hold or fasten extra length of cannula tubing. These items may be personalized by or for the patient.

[00014] Another object of the invention is to provide a covering or device, such as a“sock” or “cap," or“sleeve,” or“glove,” around the gas tank such that the tank is easier to handle and when multiple tanks are stacked next to each other the metal of one tank is not directly in contact with the metal of another tank. The covering or device may be open or closed at the bottom of the tank.

[00015] Another object of the invention is to provide one or more“pockets” or“pouches” on the aforementioned covering around the metal gas tank which can be used to store a patient’s personal items including but not limited to a cell phone, wallet, keys, identification, or other items.

[00016] Another object of the invention is to provide a“handle" or“grip" on the aforementioned covering around the metal gas tank which can be used to carry the tank.

[00017] Another object of the invention is to provide a sensor, in the regulator, in the nasal prongs or mask or elsewhere, that monitors the gas supply in the tank and provides an alert to the patient when die gas supply is low or the flow rate of gas is above or below the prescribed flow rate.

[00018] Another object of the invention is to provide a bar code, tab release, or sensor in the cannula at or near the end that is connected to the regulator, which may be scanned or activated when the cannula is first put in use and which activates a timer for a prescribed time period, such as two weeks duration, and provides a color change or an audio, visual, or vibration alert to the patient at the end of the prescribed time period when it is time to replace the cannula.

[00019] Another object of the invention is to provide a warning sensor or other device, which will produce a visual cue, sound, vibration, or other alert transmitted to the patient or to a wireless device such as a smartphone or smartwatch to alert the patient that oxygen PSI levels in the tank or other oxygen supply is low or the flow rate of gas is above or below the prescribed flow rate and to alert the patient when the battery energizing the warning device is low. Stated differently, a smartphone, Apple watch, or Fitbit could be used as a monitoring device for oxygen levels, oxygen flow rate, and battery level.

[00020] Another object of the invention is to provide a timing function, with an interface with a wireless device such as a smartphone or smartwatch, to alert the patient after a prescribed time period, such as a two week time period has transpired since the first use of the cannula, so the patient knows it is time to replace the cannula so as to avoid hardening or the deleterious effects of bacteria buildup that may occur with extended use of the cannula and possible deterioration of the tubing.

[00021] Another object of this invention to provide an improved nasal prong or nasal mask cannula and oxygen tank supply system that includes a means of differentiating a patient’s equipment from others and permits the patient to stylize his or her equipment.

[00022] Another object of the invention is to provide an improved regulator which includes an outlet, port, or coupling piece for connection to the gas source that incorporates a swivel pivot capable of rotation of at least 180° and optimally 360° in such a way as to prevent crimping of the cannula at the connection site.

A DETAILED DESCRIPTION OF THE INVENTION

[00040] As shown in FIGS. 1 and 2, a cannula tube 20 has at one end a connector 14 that is used to connect to a regulator and an oxygen tank and a connector 12 that is used to connect a nasal cannula or nasal mask. An embodiment of the invention is to an improved structure and design for a nasal cannula, or a nasal mask cannula, and in particular to provide a structure or device interposed at the location point between the end of the cannula and its connection to the regulator or the oxygen supply tank 14, concentrator or supply to prevent crimping of the tube 20. FIG. 3 A shows the cannula tube 20 according to the prior art, being crimped. As stated above, an object of the invention is to avoid crimping, and this may be accomplished as shown in FIG. 3B by providing a connecting means that prevents the cannula tube 20 to crimp. The regulator, concentrator or supply can be attached to the cannula by an anti-crimping means 22, 24, 26 which can be by using a longer tapered down tube 22 at the point of its entry and attachment to the inlet 62 from the oxygen supply system. Another anti-crimping means could be by providing an external coil like structure 26 or internal coils like structure 24 outside or within the cannula tubing 20 to avoid the crimping. FIG. 4 illustrates the external coil 26 in more detail. The use of a longer tapered down feed adapter 22, an internal coil 24 or external coil 26 prevents the cannula tube 20 from crimping at the end of the tube where it connects with the supply tank inlet 62.

[00041] Another embodiment of this invention is to provide an improved regulator which includes an external outlet, port or coupling piece, where the regulator connects to the cannula, that incorporates a swivel pivot of at least 180° (and optimally 360°), or other device which prevents crimping of the cannula.

[00042] Another embodiment of this invention is to provide a cannula as shown in FIG. 5 A and 5B that may include a clasp, clip or other device 32 or 32 A located on the cannula 20 below its bisection into two tubes 39 (as shown in Fig. 5B) such that the patient can use the clasp, clip, or other device 34 or 34A to secure the cannula to the patient’s clothing 35 to thereby reduce the tension or weight that the tubing exerts on the patient’s ears and to keep the cannula close to the body. The appearance of the clasp, clip, or other device 31 or 33 may be stylized by the patient for personal preference. Again as shown in FIG. 5A, the connector 31 may comprise a dual-sided living hinge clip with a 360 degree pivot 36, with one end 34 attached to the patient’s clothing 35 (shown in FIG. 5B) and the other end 32 attached to the cannula tube at the juncture where the cannula splits into two separate tubes to go around the patient's ears. The hinge clip 31 can be made of a metal or plastic, such as but not limited to nylon, polycarbonate, polyurethane, polyethylene or polypropylene. As shown in FIG. 5B, two integrated clasps 32A and 34A may be used without a 360 degree pivot 36.

[00043] As shown in FIGS. 6 and 7, the structure can include an oxygen tank 30, and a storage or holding means 48 to hold or store un-needed length of cannula tubing 20. The holding means 48 can be, but is not limited to a Velcro® flap 48 or similar structure for winding up and holding a particular length of cannula tubing 20. Another holding means can be a hook 44 so that the cannula tubing is wrapped around the hook 44. The system shows an (¾ tank 30 with sock 40 and Velcro® flap to hold cannula tube 20. The sock 40 could also be manufactured to fit over top of the tank. The sock 40 could be different so as to distinguish the tank from another tank as discussed below.

[00044] A further example is to have the oxygen tank 30 stored in a tank holder 63 as shown in FIG. 14. The oxygen tank 30 is shown in connection with a wheelchair 67. The tank holder 63 can be a sleeve with the bottom being sealed and the top being open to allow the oxygen tank 30 to be stored in the tank holder 63. The tank holder 63 can be made to be different than other tank holders by changing the standard tank holder, by color, size or an imprint as discussed below. The tank holder 63 can also include a storage or holding means 47 for storing or holding extra length oftubing. As shown in FIG. 14 the storage or holding means for the extra tubing can be a Velcro® flap or pocket A second storage or holding means 47A can be present to store personal items, such as keys, credit cards, cell phones etc.

[00045] Fig. 17A illustrates another embodiment where a holding means 47B is attached to a tank holder sleeve 104 that can store the cannula tube 20.

[00046] Fig. 17B illustrates a further embodiment where holding means 47C attached to a tank holder sleeve 104A that can store personal items 107 such as keys.

[00047] Another example is the use of a hook 52 as shown in FIGS. 8 and 9 that is attached to the oxygen tank 50 or cart and can be located in another area or same area on the cart. Another example is to use a clip attached to the tank holder as shown in Fig. 10 that may be opened and closed like that of an earring clip to hold the coil of extra unused cannula on the hook until needed. Examples include a hook 52 with a clip 46 like that used with an earring as shown in FIG. 10. The hook 52 on tank with clamp is used to coil extra cannula tubing and will keep extra tubing from sliding off as the tank is tilted to be pushed or carried.

[00048] FIGS. 6 and 7 illustrate one example comprising a tube-sock or cap-like structure 40 that can be placed over the top of or around the oxygen tank 30 which structure includes at least one opening through which the cannula tube 20 can be threaded and thereby secured to the oxygen tank 30, so as to provide storage for extra cannula length.

[00049] Another embodiment as shown in FIG. 13 is an improved design and structure by providing a coiling device or housing 43 which will house the tubing 20 such that the length of tubing is extended when the patient moves away from the oxygen tank 30 and needs additional length of tubing and retracts or contracts when the patient moves toward the oxygen tank and requires less length of tubing, which structure does not restrict the flow of oxygen. The coiling device or housing 43 can be light weight and easy to carry. The coiling device or housing 43 can also be of varying colors or display various logos such as the logo of a sports team or school so to distinguish the coiling device or housing 43 from other devices. This is discussed in more detail below.

[00050] The structure can further include an attachment that recoils and releases the cannula tube 20 length as needed. The attachment is used to retract the cannula tube 20 back to a device when it is pulled a certain distance from the device. The mechanism can be the same as used in the form of an electrical cord that retracts back to an appliance such as an iron or a vacuum cleaner, Included in the design of a device with a retractable cannula tube 20 can be a space for storage of the excess cannula tube 20 length. A retractable cannula tube 20 can work by providing a small storage space for excess cannula tube 20. The cannula tube 20 can be on a set of rotatable wheels which contain space for the entire length of the cannula tube 20. When the cannula tube 20 is extended outside of the device and reaches its maximum length, the user will feel tension on the cannula tube 20 and will not be able to move the device further without moving the device closer to the work area. The entire process is similar to the winding of a fishing wheel. A retractable cannula tube 20 can be on a set of rotating wheels; these wheels contain enough room for the entire length of the cannula tube 20. They also can have springs and ratchets that help lock the wheels when you pull out the cannula tube 20; this is why the cannula tube 20 doesn't snap back automatically when you tiy to extend it.

[00051 ] Instead, the cannula lube 20 may retract a tiny bit as the lock sets. When it's time to roll the cannula tube 20 back up, a patient usually would have to press a button to disengage the lock, and the wheels will turn until either the plug on the cannula tube 20 blocks further movement, or you give the cannula tube 20 another small tug to engage the lock.

[00052] U.S. Patent No. 5,255,768 entitled“Cord Winder Apparatus for a Vacuum Cleaner System” issued October 26, 1993 is incorporated by reference in its entirety including the figures, especially for showing how a retractable cord system works which includes Fig.3. FIG. 15 which is similar FIG. 3 of U.S. Patent No. 5,255,768 illustrates a cord winding mechanism that could be used to wind the cannula tube 20 as described in U.S. Patent No. 5,255,768. The structure could alternatively include a retractable mechanism such as a canister with a coiling apparatus inside, such as the mechanism used with some retractable dog leashes and tape measures, and garden hoses, which allows for the cannula tubing to be extended from the canister by pressing a button to provide extra length of cannula to permit the patient to move away from the tank and can be retracted into the canister by pressing the same or a different button when less length of cannula is needed such as when the patient moves closer to the tank. Figure 19 shows a canister 1 1 1 holding the cannula tube 20. The canister 111 has a retractable mechanism with two buttons 1 12 and 1 14 provided. When the first button 112 is depressed the cannula tubing 20 is extended and the movement stops when the button 1 12 is released. When the second button 114 is pressed the cannula tubing 20 retracts and the movement stops when the button is release. It is noted that the knob 1 16 on the regulator 60 can be used to set the pressure of the 02.

[00053] Another possibility is the button 1 12 is pushed and the cannula tubing 20 is extended and the movement stops when the button 1 12 is released. To retract the cannula tubing 20, the cannula tubing 20 gets a small tug outwardly to disengage the lock and the cannula tubing is thereby retracted into the canister 11 1.

[00054] Another embodiment of the invention is described in FIGS. 11 and 12.

[00055] A regulator sensor 57 shown in FIGS. 11 and 12 incorporated with the regulator 60 that detects the oxygen levels in pressure (converted into liters) that are currently available in the tank. The regulator 60’s display 59 maybe a dial display as shown in FIGS 11 AND 12 or digital display. This sensor may be powered by a battery, like a 9 volt or AA battery. It may also provide a signal that alerts the patient when the oxygen level or pressure is lower than as set and a signal to alert the patient that the battery is low. This could be located at the regulator's inlet 64 from the tank just before the first reduction stage measuring raw pressure points. This may have adjustable or non-adjustable settings for the purpose of alerting the patient when oxygen delivery levels are reaching a low critical level such that a new source of oxygen is needed. This may also alert the patient of what level of oxygen flow the patient’s oxygen supply is currently providing, and how much time the oxygen supply will continue to provide oxygen at that level. The sensor may interface with a wireless device so that a visual, audible, or vibration alerts may be provided by smartphone, smartwatch, or other wireless device 58 to warn the patient. Alternatively, the signal may be in the form of a light or vibration such as a flashing light that may be directed in multiple directions, iE ceiling, in front of them at eye sight levels both standing, sitting or lying down are a few examples.

[00056] A further embodiment of the invention is to provide a regulator 60 incorporating a mechanism or device 61 that provides a timing function and an interface with a digital device, such as a smartphone, a smartwatch, or other wireless device 58, such as an Apple watch or Fitbit, which timer starts when the cannula is connected to an oxygen tank and activated and notifies the patient when a pre-set time period such as two weeks (or other pre-set time) has expired, thus prompting the patient to replace the cannula tube 20 so as to avoid the deleterious effects of bacteria build up and tube hardening or deterioration. A device, mechanism, or structure 58 to provide the patient with a signal to alert when it is time to replace the cannula tube 20 which comprises a patient attaching a cannula tube to an oxygen source which connection sets a timing function, such as a timer on a smartphone or smartwatch for a pre-set time period such as two weeks, which will provide the patient a signal when the cannula is connected to the oxygen tank and activated. When the signal or alarm goes off from the timer, the patient knows to replace the cannula tube. For example, as shown in FIG. 16, a battery 80 (like a hearing aid battery, such as a 1.45 volt battery) that has a tab 82 release to start the timing junction may be sealed over the cannula port 84 that attaches to the regulator or oxygen supply, whether tank, or concentrator. To attach the cannula tube 20 and its port 84 to the oxygen source, the tab release on the battery must be pulled off, activating a sensor that interfaces with a timer on a wireless device. Thus a 2 week (or other time period) timer will be set. Alternatively, as shown in Fig. 18, a bar code 100 could be added to the cannula tube 20 that when scanned starts a timer and provides an alert from a wireless device such as a smart phone after a predetermined time interval has passed.
