CPAP nose mask

Year	Description
1997	Invention patented by Lisa A. Kidd on January 22th, 1997. 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.
