A safety valve for use in closed systems wherein there is a flow generator delivering oxygen or some other type of breathing gas to a patient. The safety valve of the present invention vents to the open atmosphere in the event that the breathing gas generated by the flow generator diminishes or terminates.

Valve for use in a gas delivery system

A combination mouth and nasal mask (40) for assisted respiration or CPAP is disclosed. The combination mask (40) has a frame (42) to the rear side of which is mounted a separate nasal cushion (44) and mouth cushion (46). Both the nasal cushion (44) and the mouth cushion (46) separately form a rolled edge seal around the patient's face in the vicinity of the nose and in the vicinity of the lips. Inlet air is communicated from within the housing (48) to the mouth chamber, circumscribed by the mouth cushion (46) by means of one or more interconnecting tubes (62). The proportion of air communicated to the mouth chamber (48) is controlled by the sizing and number of the tube(s), thus providing for free flow of air, restricted flow of air and pressure equalization, or zero flow of air. A mouth mask (10) for assisted respiration or CPAP also is disclosed.

Facial masks for assisted respiration or CPAP

A mask and harness assembly (10). The assembly (10) includes a mask (12) a harness (14) including at least one strap (16) connected to the mask (12) and at least one fluid delivery tube (18) connected to, and in fluid communication with, the mask (12). The strap(s) (16) and the tube(s) (18) being adapted to locate the mask (12) at a predetermined location on the head of the wearer.
