DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0032] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

[0033] Referring now to FIGS. 1-3, a patient 100 typically receives oxygen through a continuous tube 102 that loops behind the ears 104 of the patient 100. Nasal cannula prongs 110 are formed or secured to the tube 102 and adapted to slide into the nostrils of the patient to supply oxygen. Oxygen travels through the tube 102 and is inhaled by the patient 100 through the nose 108.

[0034] The device 106 is used to secure the nasal cannula prongs 110 within the nose 108 of the patient 100. For example, an upper portion of the device 106 includes a pair of opposing legs 114 that are configured to slide over the nasal septum 112 of the patient 100 and uses a friction fit to hold the device 106 in place. The opposing legs 114 are biased to provide compression as the legs 114 are slightly moved apart when sliding over the nasal septum 112. A width 116 between the legs 114 may vary depending on the patient 100, but the width 116 must be smaller than the width of the nasal septum 112. For example, a small width 116 between the legs 114 is required a proper fit over the nasal septum 112 of a child, and a larger width 116 is required for adults. The upper portion of the device 106 may be U-shaped with rounded edges and corners to minimize any discomfort to the patient 100. In addition, gel pads or other cushioning material may be secured to an inside portion of the legs 114 to soften the contact area of the device 106 to the nasal septum 112. For example, the pair of opposing legs 114 are flexible and the distance between the opposing legs 114 can be adjusted. A pair of gel pads are attached at the end of opposing legs 114. The pair of opposing legs 114 can be inserted to the nostril and the pair of gel pads are attached to the inner surface of the nostril. This will improve the comfortability of the patient and the pair of gel pads can push the nostril inner surface and make the nostril cavity a little wider to facilitate easier breathing for the patient.

[0035] Referring now to FIG. 4, the device 106 includes a clip 118 that is configured to secure the device 106 to the tube 102. In this particular illustrative embodiment, the clip 118 is hook-shaped with an inside diameter 120 large enough to fit around an outside diameter of the tube 102 without interfering with the flow of oxygen through the tube 102, but small enough to provide a friction fit between the clip 118 and the tube 102. The clip 118 is made of the relatively elastic material being looped over itself to accommodate the oxygen delivery tube 102. The clip 118 has an opening 120 for receiving the oxygen delivery tube 102. More than one hook can be used. For example, the clip 118 can include two hooks in parallel with each other.

[0036] Referring now to FIGS. 5 and 6, an alternative illustrative embodiment is shown. The alternative device 200 similarly includes the clip 118 to secure the alternative device 200 to the tube 102 but has a different configuration to secure the alternative device 200 to the nasal septum 112. For example, prongs 202 of the alternative device 200 are biased and configured so that they can be manipulated by pinching the proximate ends. As shown in FIG. 6, as the proximate ends of the prongs 202 are pressed together and pressure is applied, the opposing distal ends of the prongs 202 move further apart about a fulcrum location. This manipulation allows the prongs 202 to slide over the nasal septum 112 without requiring tissue of the nasal septum to spread the prongs. Accordingly, once the alternative device 200 is in the desired location, the pressure on the proximate ends of the prongs 202 can be released, causing the distal ends of the prongs 202 to move closer together and remain securely to the nasal septum 112, as the width 204 between the prongs 202 is less than a width of the nasal septum 112. Accordingly, once the device 200 is in the desired location, the pressure on the proximate ends of the prongs 202 is released causing the distal ends of the prongs to move closer together and remain securely to the nasal septum.

[0037] Alternately, referring to FIGS. 7-10, the pair of legs/prongs can be eliminated altogether. In a device 300, a clip 118 is secured to an adhesive strip 330 which adheres to the columella 332 (i.e., the fleshy external termination) of the nasal septum 112. The adhesive strip 330 can use medical grade adhesive to hold the strip in place. If needed, additional medical adhesive can be applied to the strip prior to placing it on the columella 332 for extra strength. The strip 330 can be square, circular or any other shape suitable for attaching to the columella 332. An example dimension of the strip is about 0.64 centimeters in width and about 1.3 centimeters in length. Other dimensions can be used to accommodate a patient. The strip 330 can also have a curved support base. The curvature can facilitate placing the strip 330 on the columella 332 more easily and also help to center the strip 330 to the columella 332.

[0038] The clip 118 can be secured to the strip 330 via a hook-and-loop-type of fastener or another suitable fastener. The clip 118 can be permanently or releasably secured to the adhesive strip 330. In the releasable attachment, the clip 118 can be easily removed and/or reattached to the adhesive strip 330, for example, via attraction of magnets having opposite poles. For example, each of the adhesive strip 330 and the clip 118 can be attached to a magnet respectfully having opposite poles. The attraction of opposite poles of the respective magnet therefore can hold the strip 330 and the clip 118 together.

[0039] The clip 118 can be rotated relative to the adhesive strip 330 such that the opening 120 is pointed at a certain orientation or otherwise desired by a user to achieve a higher comfort level. The clip 118 has an opening 120 for receiving the oxygen delivery tube 102. The clip 118 is made of a relatively elastic material to receive the oxygen delivery tube 102 and accommodate the oxygen delivery tube 102. Preferably, a non-adhesive pull tab 334 is located at one end of the strip to facilitate removal. With the tube 102 secured to the clip 118 and the strip adhered to the columella 332, the cannula prongs 110 extend securely into the nose 108. The strip 330 can be applied to the columella 332 before or after securing the tube 102 to the clip 118. When it is desired to remove the device 300, the tab 334 is grasped and the strip 330 is removed from the columella 332. The tube 102 could, if desired, be removed from the clip 118 prior to or after removal of the strip 330 from the columella 332.

[0040] According to another embodiment of the present invention, a method of securing an oxygen tube to a patient includes using the device 300 securing an oxygen tube to the clip (e.g., clip 118) of the device 300 and attaching the adhesive strip (e.g., adhesive strip 330) to the columella of the nasal septum. Alternatively or additionally, the adhesive strip 330 can also be attached to the skin between upper lip and nose instead of columella 332.

[0041] According to another embodiment of the present invention, an extension member 400 can be mounted between the clip 118 and the adhesive strip 330 of FIGS. 7-10 or between the clip 118 and the pair of opposing legs 114. For example, as shown in FIGS. 11-13, the extension member 400 can be in a retracted state as shown in FIG. 11, a partially extended state as shown in FIG. 12, or a fully extended state as shown in FIG. 13 to achieve a desired length for a user. The extension member 400 can introduce a distance between the clip 118 and the pair of opposing legs 114 or between and the clip 118 and the adhesive strip 330. In a preferred embodiment, the cross section of the end of the extension member 400 attaching to the adhesive strip 330 is greater than the cross section of the end of the extension member 400 attaching to the clip 118 to provide more stability. A desired placement of the air delivery prongs relative to the oxygen delivery tube 102 can thus be achieved. For example, the extended extension member 400 can result in the air delivery prongs being just inside or just outside of nostrils such that an oxygen delivery tube (e.g., oxygen delivery tube 102) has no contact with patient's nostrils and irritation from contact is minimized. For example, the extension member 400 can be designed as a plurality of slidable sections in a telescoping arrangement.

[0042] Referring to FIG. 14, according to another embodiment of the invention, the clip 118 of the devices described in FIGS. 1-13 can include appendages 122 on the respective ends to facilitate securing the oxygen tube (not shown) inside the clip 118.

[0043] Referring to FIGS. 15 and 16, according to another embodiment of the present invention, the clip 118 can have a first 124 and a second portion 126. The second portion 126 is secured to the adhesive strip 330. The first portion 124 can be opened to receive an oxygen tube (shown in FIG. 15) and closed and snap onto the second portion 126 (shown in FIG. 16) to secure an oxygen tube in place. The clip 118 is preferably made of pliable plastic material such that the first portion 124 is easily snapped into the second portion 126 and a user can manipulate (e.g., open, close, rotate, etc.) at least a portion of the clip 118 to secure the oxygen tube.

[0044] Referring to FIGS. 17-19, according to another embodiment of the present invention, a first portion 124 of the clip 118 is elastic and the first portion 124 can be stretched over the oxygen tube and attached to a second portion 126 of the clip 118. The second portion 126 can be rigid and pliable.

[0045] According to another embodiment of the present invention, referring to FIGS. 20-21, the clip 118 is a hook. The size of the hook can vary to accommodate cannulas with different diameters. The hook can be an integral piece or assembled pieces including a support base 128 configured to be affixed to/embedded into the adhesive strip 330. The hook can be extended as desired. For example, the hook can move up and down along an extension pole. FIG. 20 shows the hook in a retracted state and FIG. 21 shows the hook in an extended state. This would allow a patient to adjust the position and orientation of the hook to achieve a desired placement of the air delivery prongs. The hook also can be attached to the adhesive strip 330 via a hinge arrangement, a sliding arrangement, a ball and socket arrangement, Velcro, and other suitable arrangements. As such, the position and/or orientation of the hook can be adjusted via the hinge and/or ball and socket arrangement, a sliding mechanism, and the like. In the sliding mechanism, a support base having an elongated opening is attached to the adhesive strip 330 and the clip 118 can slide along the elongated opening of the support base.

[0046] The hook can be flexible or bendable for use to fit around the oxygen tube. The flexible design can enable to adapt to the oxygen tube with varying diameters. When the oxygen tube has a smaller diameter, the hook can be bended and completely enclose the oxygen tube. When the oxygen tube has a larger diameter, the hook may not completely enclose the oxygen tube, but still hold the oxygen tube in place. The hook can be made of a bendable leg (e.g., leg made of a plastic strip encased in metal) such that it can be molded around the oxygen tube and stay in place. The hook can be made of bendable straight extension leg that one can roll up and wrap around the oxygen tube.

[0047] The present invention can eliminate the need for a cannula that splits into two tubes so the oxygen can be looped around a user's ears. The adhesive strip 330 and/or the opposing legs 114 can securely attach the cannula to the user.
