| Abstract: |
A comfortable, leak-resistant CPAP nose mask (10) is provided having a soft, resilient, synthetic resin body (12) and an air source connection fitting (14). The body (12) presents an internal nose-receiving cavity (20) as well as a generally triangular nose entrance opening (16) and a spaced, opposed, inhale/exhale opening (18); the openings (16,18) are in communication with the cavity (20). The entrance opening (16) is defined by a circumscribing flange (20) and an inboard, pliable, inwardly extending, sealing lip (32). A metallic, deformable, shape-retaining reinforcing member (42) is secured to the outer surface of the flange (22) and extends over the bridge (24) and sidewall regions (26, 28) of the flange (22). The member (42) can be readily shaped so as to accommodate the shape and contour of the user's nose and face.

I claim:
1. A nose mask for receiving a patient's nose and engaging the patient's nose and face, said mask comprising a hollow body including wall structure defining an internal nose-receiving cavity, a nose entrance opening and a spaced inhale/exhale opening, said openings in communication with said cavity, said entrance opening-defining structure having a peripheral flange for directly engaging the top of a patient's nose, the sides of the patient's nose and the cheek regions adjacent the nose, and the patient's upper lip area beneath the nose, and a thin, pliable lip inboard of said flange and extending into said nose entrance opening, said lip being configured for facilitating a seal between said mask body and the patient's nose and face to minimize leakage of positive pressure gas from the nose mask, said flange and lip, at the areas thereof engaging the top of the patient's nose and the sides of the patient's nose and the cheek regions adjacent the nose and diverging from each other, said nose entrance opening being generally tria-ngular in configuration, said range and lip each having a pair of oblique, downwardly extending sidewall portions said lip sidewall portions being thinner and more pliable than said flange sidewall portions.
