Abstract:
1. A face mask for sealing against the atmosphere a wearer's mouth and nose and supplying pressurized inhalant gas and providing means for exhalation from a patient engaged to the face mask, the improvement comprising a generally conical shell comprising a hose connector cylinder, a representation of a face on an outside surface of said shell, whereby an outward extension of the hose connector cylinder from the shell appears to form a nose of said face representation, and an exhaust valve in a location where an external viewer of the face mask would associate with a location of a mouth of the face representation; the exhaust valve comprises a flexible component, so that when a patient is engaged to the face mask and exhales into the shell, the flexible component elevates from a surface defined by a surrounding portion of an outside surface of the shell in imitation a flapping tongue of the face representation; the face representation comprises representations of one or more eyes on the outside surface of the shell opposite the location of the hose connector cylinder; the shell further comprises formed extensions at lower portions of the shell near to or extending from said peripheral edge, said formed extensions being adapted to engage with straps to secure the face mask to a patient's head and having a shape and location so that an external viewer would associate said formed extensions with ears of the face representation; the shell further comprises an exhaust opening defined in the location of the exhaust valve, the exhaust opening being interrupted by support extensions from the shell for support of a flexible portion of the exhaust valve; the flexible component further comprises an attachment end which is secured to the shell at a position proximal to the hose connector cylinder and a flexible portion which extends to sealingly cover the exhaust opening when a patient using the face mask is not exhaling; and the face representation comprises representations of a lip or lips on the outside surface of the shell surrounding the location of the exhaust valve.
