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.

1 . A respiration assist mask, comprising:
 a ventilation interface including a gas entry port defined in the ventilation interface to facilitate supplying a gas to the ventilation interface;   a cushioned facial interface connected to said ventilation interface, the facial interface having a gas exit shaped to gas-tightly seal only the mouth from the environment;   at least one removable nasal insert removably coupled in flow communication to an orifice in an upper portion of the cushioned facial interface; and   a cavity defined within the cushioned facial interface between the gas entry port and an end of the at least one removable nasal insert farthest from the cushioned facial interface.   
     
     
         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 that extends away therefrom, the elongated portion facilitates at least one of providing a seal under a chin of the user and preventing movement of a lower jaw of the user. 
     
     
         3 . The respiration assist mask of  claim 1 , wherein the at least one removable nasal insert is coupled with a second nasal insert. 
     
     
         4 . The respiration assist mask of  claim 1 , further comprising at least one protrusion for the attachment of headgear. 
     
     
         5 . The respiration assist mask of  claim 1 , wherein the ventilation interface and the cushioned facial interface are removably attached. 
     
     
         6 . The respiration assist mask of  claim 1 , wherein the cushioned facial interface comprises a membrane that facilitates providing a seal across an upper lip and around a mouth of a user. 
     
     
         7 . A respiration assist mask, comprising:
 a ventilation interface;   a cushioned facial interface comprising a gas exit shaped to gas-tightly seal only the mouth;   at least one nasal insert;   a cavity defined within the cushioned facial interface between the ventilation interface and an end of the at least one nasal insert farthest from the cushioned facial interface; and   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 an upper portion of the cushioned facial interface and creating a seal therebetween.   
     
     
         8 . The respiration assist mask of  claim 7 , 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. 
     
     
         9 . The respiration assist mask of  claim 7 , wherein the at least one nasal insert is joined to a second nasal insert. 
     
     
         10 . The respiration assist mask of  claim 7 , wherein the cushioned facial interface comprises a membrane that facilitates providing a seal across an upper lip and around a mouth of a user. 
     
     
         11 . The respiration assist mask of  claim 7 , wherein the ventilation interface further comprises at least one protrusion for the attachment of headgear. 
     
     
         12 . The respiration assist mask of  claim 7 , wherein the ventilation interface has at least one exhaust port defined therein. 
     
     
         13 . A respiration assist mask of  claim 1 , wherein the ventilation interface comprises at least one exhalation port defined therein. 
     
     
         14 . The respiration assist mask of  claim 1 , wherein the membrane has a periphery edge at the gas exit that is configured to not contact the nose during use. 
     
     
         15 . A respiration assist mask of  claim 7 , wherein the membrane has a periphery edge at the gas exit that is configured to not contact the nose during use. 
     
     
         16 . A respiration assist mask, comprising:
 a ventilation interface including a gas entry port defined in the ventilation interface to facilitate supplying a gas to the ventilation interface;   a cushioned facial interface connected to said ventilation interface, the facial interface having a gas exit shaped to gas-tightly seal only the mouth from the environment;   at least one nasal insert coupled in flow communication with an angled surface of an upper portion of the cushioned facial interface; and   a cavity defined within the cushioned facial interface between the gas entry port and an end of the at least one removable nasal insert farthest from the cushioned facial interface.   
     
     
         17 . The respiration assist mask of  claim 16 , wherein at least a portion of the angled surface extends above the upper portion. 
     
     
         18 . The respiration assist mask of  claim 16 , wherein at least a portion of the angled surface extends below the upper portion. 
     
     
         19 . The respiration assist mask of  claim 16 , wherein the cushioned facial interface comprises a membrane that facilitates providing a seal across an upper lip and around a mouth of a user. 
     
     
         20 . The respiration assist mask of  claim 16 , wherein the membrane has a periphery edge at the gas exit that is configured to not contact the nose during use.
