Abstract

A respiration assist mask having an input gas feed tube, a ventilation interface, a facial interface and nasal inserts. The gas feed tube can connect to the ventilation interface and form a seal. The ventilation interface may be joined with the facial interface to form a seal between the ventilation interface and the facial interface, as well as between the facial interface and the face of a user. Additionally, nasal inserts may be inserted into a portion of the facial interface and form a seal between the inserts and the facial interface.

Claims

1. A respiration assist mask, comprising:

a ventilation interface including at least one exhalation port defining a gas entry port to be connected to a positive gas pressure source supplying a gas to said ventilation interface;

a cushioned facial interface connected to said ventilation interface, the facial interface having a gas exit shaped to gas-tightly seal from the environment; and

at least one removable nasal insert.

2. The respiration assist mask of claim 1, wherein the cushioned facial interface further comprises an elongated portion at the bottom portion of the interface.

3. The respiration assist mask of claim 1, wherein the cushioned facial interface further comprises at least one membrane.

4. The respiration assist mask of claim 1, wherein the at least one removable nasal insert is coupled with a second nasal insert.

5. The respiration assist mask of claim 1, further comprising at least one protrusion for the attachment of headgear.

6. The respiration assist mask of claim 1, wherein the ventilation interface and the cushioned facial interface are removably attached.

7. The respiration assist mask of claim 1, wherein the cushioned facial interface has at least one interior membrane.

8. The respiration assist mask of claim 1, wherein the cushioned facial interface has a first membrane for providing a seal and a second membrane for providing support.

9. The respiration assist mask of claim 1, wherein the cushioned facial interface has a first interior membrane and a second interior membrane, the first interior membrane for providing a gas tight seal against the face of a user and the second interior membrane being thicker than the first interior membrane and providing structural rigidity to the facial interface and limiting movement of the respiration assist mask.

10. The respiration assist mask of claim 9, wherein the distance between the first interior membrane and the second interior membrane is larger at a top and bottom portion of the cushioned facial interface than the distance between the first interior membrane and the second interior membrane at a left or right side portion of the cushioned facial interface.

11. The respiration assist mask of claim 1, wherein the cushioned facial interface has a curved periphery that adheres to the contours of a face of a user.

12. A respiration assist mask, comprising:

a gas supply tube;

a ventilation interface;

a cushioned facial interface; and

a least one nasal insert;

the gas supply tube removably connected to the ventilation interface and creating a seal therebetween, the cushioned facial interface removably connected to the ventilation interface and creating a seal therebetween, and the at least one nasal insert removably connected to the cushioned facial interface and creating a seal therebetween.

13. The ventilation interface of claim 12, wherein the cushioned facial interface has a first exterior membrane and a second interior membrane.

14. The ventilation interface of claim 12, wherein the cushioned facial interface creates a first seal between the cushioned facial interface and an upper lip of a user and a second seal between the cushioned facial interface and a chin of a user.

15. The ventilation interface of claim 12, wherein the at least one nasal insert is joined to a second nasal insert.

16. The ventilation interface of claim 12, wherein the cushioned facial interface has a first membrane and a second membrane, the first membrane being thinner than the second membrane.

17. The ventilation interface of claim 12, wherein the cushioned facial interface has a first membrane and a second membrane, the first membrane being separated from the second membrane by a greater distance at top and bottom portions of the cushioned facial interface than at side portions of the cushioned facial interface.

18. The ventilation interface of claim 12, wherein the front face has at least one moveable and rotatable post for the attachment of head gear.

19. The ventilation interface of claim 12, wherein the cushioned facial interface is formed out of silicone.

20. The ventilation interface of claim 12, wherein the front face has at least one exhaust port.
