Abstract
A patient interface having a cushion for engagement with the face of a user, a shell having an extension with a forehead support connected to the extension. The forehead support has a hinge so that the forehead support can be deformed to conform to the user's forehead. The patient interface also has a pivotable coupling defined by a body and a coplanar conduit that extends radially from the body. The coupling also has a port that allows access within the cavity formed by the cushion so that the port and coupling may rotate together.
Claims21
A patient interface device comprising:
- a cushion having a cavity;
- a shell for supporting the cushion, the shell having an opening in communication with the cavity;
- and
- a coupling in communication with the opening, the coupling having a port.
A patient interface device comprising:
- a cushion having a cavity;
- a shell for supporting the cushion, the shell having an opening in communication with the cavity;
- a coupling in communication with the opening, the coupling being pivotable, the coupling having a generally cylindrical coupling body and a coupling conduit radially extending outward from the coupling body, the coupling body and the coupling conduit being approximately coplanar.
A patient interface comprising:
- a cushion having a cavity;
- a shell having an opening in communication with the cavity, the shell having an extension extending from the shell;
- and
- a forehead support connected to the extension, the forehead support having at least one hinge so that the forehead support may be deformed.
A patient interface comprising:
- a cushion having a lip, the lip having a plurality of slots;
- a shell having a plurality of slots, the shell includes an internal surface and an external surface;
- and
- a retaining ring having a plurality of detents, each detent being fitted through a corresponding slot on the cushion and through a corresponding slot on the shell, the detent having a hook portion that engages the external surface of the shell.
A patient interface device comprising:
- a shell;
- a forehead support connected to the shell;
- a headgear assembly;
- at least one forehead latch interconnected between the headgear assembly and the forehead support;
- the forehead latch being releaseably coupled to the forehead support;
- and
- at least one shell latch interconnected between the headgear assembly and the shell, the shell latch being releasably coupled to the shell.
A patient interface for use with a gas delivery conduit, the patient interface comprising:
- a means for cushioning the patient interface, the means defining an internal cavity;
- a means for supporting the cushioning means;
- and
- a means for coupling the patient interface to the gas delivery conduit, the coupling means including a means for pivoting the coupling means, the coupling means also including a means for accessing the internal cavity defined by the cushioning means.
