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.
Claims20
A respiration assist mask, comprising:
- a ventilation interface including a gas entry port defined in the ventilation interface;
- a positive gas pressure source tube coupled to the gas entry port of 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, the cushioned facial interface comprising at least one first exterior membrane that facilitates providing a seal across an upper lip and around a mouth of a user, and at least one second interior membrane positioned adjacent the at least one first exterior membrane such that a distance is defined therebetween, wherein the entire portion of the at least one first exterior membrane that facilitates providing a seal across an upper lip of a user has a first edge that extends toward the gas exit shaped to gas-tightly seal only the mouth that does not extend further than an adjacent second edge of the at least one second interior membrane;
- 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.

- 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 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 an upper portion of the cushioned facial interface and creating a seal therebetween.
