## Abstract

According to one embodiment, a device is disclosed. The device includes a nasal cannula having prongs to supply air and covers inserted over the prongs to prevent discomfort during use of the nasal cannula.

## Claims

### Claim 1

A device comprising:
a nasal cannula having prongs to supply air; and
foam covers inserted over the prongs to diffuse air exiting from the prongs in order to prevent discomfort during use of the nasal cannula, wherein the foam covers are impregnated with lubricating gel to humidify the diffused air.

### Claim 2 (depends on 1)

The device of claim 1 wherein foam on the foam covers provides tension to hold the foam covers on to the prongs.

### Claim 3 (depends on 1)

The device of claim 1 wherein the foam covers are shaped to fit and open nasal passages.

### Claim 4 (depends on 1)

The device of claim 1 wherein the lubricating gel is a saline gel.

### Claim 5 (depends on 1)

The device of claim 1 wherein the covers comprise a hole to fit over the prongs.

### Claim 6 (depends on 5)

The device of claim 5 wherein the hole has a diameter smaller than a tip of a prong to enable compression of the foam to hold a cover on to a prong.

### Claim 7 (depends on 5)

The device of claim 5 wherein the foam covers each comprise inserts within the hole to hold the foam covers on to the prongs.

### Claim 8 (depends on 7)

The device of claim 7 wherein the inserts snap to the prongs.

### Claim 9 (depends on 7)

The device of claim 7 wherein the inserts are screwed on to the prongs.

### Claim 10

A device comprising foam covers inserted over nasal cannula prongs to diffuse air exiting from the prongs in order to prevent discomfort during use of the nasal cannula, wherein the foam covers are impregnated with lubricating gel to humidify the diffused air.

### Claim 11 (depends on 10)

The device of claim 10 wherein the lubricating gel is a saline gel.

### Claim 12 (depends on 10)

The device of claim 10 wherein the foam covers comprise a hole to fit over the prongs.

### Claim 13 (depends on 12)

The device of claim 12 wherein a hole has a diameter smaller than a tip of a prong to enable compression of the foam to hold a cover on to a prong.

### Claim 14 (depends on 12)

The device of claim 12 wherein the foam covers each comprise inserts attached within the hole to hold the foam covers on to the prongs.

### Claim 15 (depends on 14)

The device of claim 14 wherein the inserts snap to the prongs.
