Abstract

An assembly includes a nasal cannula with nostril outlet prongs and a pair of oxygen inlets. A pair of oxygen feed lines are connected at one end to the cannula inlets and at their other ends are adapted for connection to an oxygen tank. Soft, flexible face guards are attached to portions of the cannula running across the face of the patient, and are positioned so as to lie generally adjacent to the cheek of the patient. The face guards, which may be permanently or temporarily attached to the cannula, distributes the force of the cannula against the patient'"'"'s skin so as to minimize or eliminate skin impressions.

Claims

1. A nasal cannula assembly, comprising:

a nasal cannula having a pair of apertured nostril outlet prongs and a pair of oxygen inlets;

a pair of oxygen feed tubes, each tube having an inlet and an outlet, the tubes'"'"' outlets being connected to the cannula inlets respectively, and the feed tube inlets being adapted for connection to a source of pressurized oxygen, each of the feed tubes intermediate their ends adapted to be looped over a user'"'"'s ears, respectively; and

a pair of face guards attached to respective small segments of the feed tubes between the nasal cannula and portions of the feed tubes adapted to be looped over the user'"'"'s ear to lift an adjacent portion of the feed tubes away from a user'"'"'s face and prevent irritation thereof, each face guard having a surface adapted to rest against a user'"'"'s face and including a pillow-like, rectangular cushioned pad of soft batting material within a flexible enclosure having rounded edges, disposed between the feed tube and the user'"'"'s cheek, wherein the width of each face guard taken perpendicular to a longitudinal axis of the small segment of the respective feed tube to which the face guard is attached, is substantially greater than the diameter of the feed tube, said surface adapted to rest against a user'"'"'s face being totally free of adhesive.

2. The nasal cannula assembly of claim 1, wherein each face guard includes a first portion comprising the pillow-like cushioned pad, and a comparatively thin second portion which overlies the respective feed tube and, with the first portion, cooperatively secures the feed tube therebetween.

3. The nasal cannula assembly of claim 2, including means for fastening the first portion to the second portion.

4. The nasal cannula assembly of claim 3, wherein the fastening means comprises hook and loop fasteners.

5. The nasal cannula assembly of claim 3, wherein the fastening means comprises an adhesive.

6. The nasal cannula assembly of claim 5, wherein the second portion comprises an adhesive-coated tape, and wherein the first portion includes an upper surface to which the adhesive-coated tape is adhered.

7. The nasal cannula assembly of claim 6, including non-stick release paper between the first and second portions of the face guard, which release paper is removable prior to attaching the face guard to the respective feed tube.

8. A nasal cannula assembly, comprising:

a nasal cannula having a pair of inlets;

a pair of feed tubes, each tube having an inlet and an outlet, the tube outlets being connected to the cannula inlets respectively; and

face guard means attached to small segments of the feed tubes, for lifting an adjacent portion of the feed tubes away from a user'"'"'s face to prevent irritation thereof, the face guard means having a surface adapted to rest against a user'"'"'s face and including a generally rectangular pillow-like cushioned pad of soft batting material within a flexible enclosure having rounded edges and disposed between a respective feed tube and a user'"'"'s cheek, said surface adapted to rest against a user'"'"'s face being totally free of adhesive, and means for fastening the cushioned pad to the respective feed tube in a manner which will minimize localized pressure to a user'"'"'s cheek adjacent the face guard means when a force is applied to the face guard means opposite a user'"'"'s cheek.

9. The nasal cannula assembly of claim 8, wherein the fastening means comprises an adhesive-coated tape.

10. The nasal cannula assembly of claim 9, wherein the cushioned pad includes an upper surface to which the adhesive-coated tape is adhered.

11. The nasal cannula assembly of claim 10, including non-stick release paper between the adhesive-coated tape and the upper surface of the cushioned pad, which release paper is removable prior to mounting the face guard means to the respective feed tube.

12. A nasal cannula assembly, comprising:

a nasal cannula having a pair of inlets;

a pair of feed tubes each having an inlet and an outlet, the tube outlets being connected to the cannula inlets respectively; and

face guard means attached to the feed tubes, for lifting an adjacent portion of the feed tubes away from a user'"'"'s face to prevent irritation thereof, the face guard means having a surface adapted to rest against a user'"'"'s face and including a first portion which underlies a respective feed tube to provide a generally rectangular face-engaging cushioned pad comprising a batting material within a flexible enclosure, wherein the width of the cushioned pad is substantially greater than the diameter of the respective feed tube, and a comparatively thin second portion which overlies the respective feed tube and, with the first portion, cooperatively secures the feed tube therebetween, said surface adapted to rest against a user'"'"'s face being totally free of adhesive.

13. The nasal cannula assembly of claim 12, including hook and loop fasteners for fastening the first portion to the second portion.

14. The nasal cannula assembly of claim 12, wherein the second portion comprises an adhesive-coated tape, and wherein the first portion includes an upper surface to which the adhesive-coated tape is adhered, to provide means for fastening the first portion to the second portion.

15. The nasal cannula assembly of claim 14, including non-stick release paper between the first and second portions of the face guard, which release paper is removable prior to placement of the face guard means over and around the respective feed tube.
