Ventilation interface

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.

         2 . The ventilation device of  claim 1 , wherein the at least one nasal pillow is coupled to a second removable nasal pillow with a connecting member. 
     
     
         3 . The ventilation device of  claim 1 , wherein the cushioned facial interface has a membrane with a top edge and the at least one nasal pillow has a nasal insert portion with a bottom edge, and the distance between the top edge of the membrane and the bottom edge of the nasal insert portion that is approximately  0 . 030 ″ to  2 ″. 
     
     
         4 . The ventilation device of  claim 1 , wherein the cushioned facial interface has two grooves between the at least three flanges. 
     
     
         5 . The ventilation device of  claim 4 , wherein the height of the two grooves is substantially the same. 
     
     
         6 . The ventilation device of  claim 1 , wherein the at least one removable nasal pillow is a first removable nasal pillow and a second removable nasal pillow, wherein the first removable nasal pillow may couple with the cushioned facial interface at a first height and the second removable nasal pillow may couple with the cushioned facial interface at a second height. 
     
     
         7 . A ventilation device, comprising:
 a ventilation interface adapted to connect to a gas source supplying a gas to the ventilation interface;   a cushioned facial interface coupled with the ventilation interface, the cushioned facial interface having a gas exit configured to seal over the mouth of a user and having at least two receiving flanges at a receiving hole; and   at least one removable nasal pillow, the at least one removable nasal pillow having at least two flanges with at least one groove formed between the at least two flanges, wherein the at least one groove receives at least one receiving flange to couple the at least one removable pillow with the cushioned facial interface.   
     
     
         8 . The ventilation device of  claim 7 , wherein the at least one nasal pillow is coupled to a second removable nasal pillow with a connecting member. 
     
     
         9 . The ventilation device of  claim 7 , wherein the cushioned facial interface has a membrane with a top edge and the at least one nasal pillow has a nasal insert portion with a bottom edge, and the distance between the top edge of the membrane and the bottom edge of the nasal insert portion that is approximately 0.030″ to 2″. 
     
     
         10 . The ventilation device of  claim 7 , wherein the cushioned facial interface has a groove between the at least two receiving flanges. 
     
     
         11 . The ventilation device of  claim 7 , wherein the height of the at least two receiving flanges of the cushioned facial interface is substantially the same. 
     
     
         12 . The ventilation device of  claim 7 , wherein the height of the at least two flanges of the at least one removable nasal pillow is substantially the same. 
     
     
         13 . The ventilation device of  claim 7 , wherein the at least one removable nasal pillow is a first removable nasal pillow and a second removable nasal pillow, wherein the first removable nasal pillow may couple with the cushioned facial interface at a first height and the second removable nasal pillow may couple with the cushioned facial interface at a second height. 
     
     
         14 . A ventilation device, comprising:
 a ventilation interface adapted to connect to a gas source supplying a gas to the ventilation interface;   a cushioned facial interface coupled with the ventilation interface, the cushioned facial interface having a gas exit configured to seal over the mouth of a user;   at least one removable nasal pillow having at least two receiving flanges; and   the cushioned facial interface having a receiving hole with at least two flanges and one groove formed between the two flanges , wherein the groove receives at least one receiving flange to couple with the at least one removable nasal pillow.   
     
     
         15 . The ventilation device of  claim 14 , wherein the at least one nasal pillow is coupled to a second removable nasal pillow with a connecting member. 
     
     
         16 . The ventilation device of  claim 14 , wherein the cushioned facial interface has a membrane with a top edge and the at least one nasal pillow has a nasal insert portion with a bottom edge, and the distance between the top edge of the membrane and the bottom edge of the nasal insert portion that is approximately 0.030″ to 2″. 
     
     
         17 . The ventilation device of  claim 14 , wherein the at least one removable nasal pillow has a groove between the at least two receiving flanges. 
     
     
         18 . The ventilation device of  claim 14 , wherein the height of the at least two flanges of the cushioned facial interface is substantially the same.
