Abstract

A nasal ventilation interface including a pair of tubes configured to deliver a ventilation gas. The tubes are attachable at a first end to a ventilation gas supply hose and engageable at a second end with a person'"'"'s nostril. A coupler is configured to align the pair of tubes with the person'"'"'s nostrils, wherein each tube has an absence of pneumatic interconnection with the other tube.

Claims

1. A nasal ventilation interface comprising:

a pair of tubes, the tubes configured to engage a user'"'"'s nostrils at a distal end and configured to attach to a ventilation gas supply hose at a proximal end; and

a coupler configured to connect the pair of tubes having a movable joint between the pair of tubes, wherein the coupler further comprises a length adjustor to adjust the length of the coupler and to align the tubes with the nostril foramen, and wherein the coupler pneumatically interconnects the pair of tubes.

2. The interface of claim 1, wherein the movable joint comprises a swivel to permit rotational movement of the tubes in at least one plane, and align each tube with a nostril foramen.

3. The interface of claim 1, wherein the coupler is removably attachable and available in a plurality of sizes or lengths so as to allow the user to adjust the spacing between the distal end tubes.

4. The interface of claim 1, further comprising a sealing member, wherein the sealing member comprises an enlarged diameter at a distance proximal to the distal end wherein the enlarged diameter creates the general configuration of a step, and wherein the enlarged diameter is a dimension larger than the nostril rim inner diameter, and wherein when used the step engages the nostril rim to effect a seal and to prevent over penetration of the tubes into the nostril.

5. The interface of claim 4, wherein the sealing members comprise a double seal, wherein the step comprises a first seal on the rim of the nostril and wherein a second seal occurs inside the nostril and wherein the second seal further comprises a at least on ring on or near the distal end of the sealing member.

6. The interface of claim 5, wherein the sealing member further comprises an attachment member, wherein the attachment members attaches the sealing member to the tube distal end and comprises a locking device, wherein the locking device prevents inadvertent dislodgment of the sealing member from the interface tubes.

7. The interface of claim 4, wherein the sealing members further comprise a leash configured to be grasped with fingers for attachment and removal of the cushion.

8. The interface of claim 4, wherein the sealing members are air filled.

9. The interface of claim 4, wherein the sealing members are comprised of a material having a durometer of about 40 to about 70 Shore OO durometer.

10. The apparatus of claim 1, wherein the distal ends of each of the pair of tubes swivels together in at least one plane.
