PROBLEM TO BE SOLVED: To provide a swivel elbow and a mask assembly by which air intake and CO 2 gas removal are smoothly performed. SOLUTION: In the elbow assembly, the elbow (160) includes a first end portion engaged with a gas delivery tube (168) and a second end portion adapted to a mask (5). The elbow further forms an inlet port capable of delivering incoming gas to a nasal breathing cavity of the mask and an exhaust port separated from the inlet port by a baffle (161). The baffle includes an arch shape portion and can deliver exhaust gas from the nasal breathing cavity. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide ports which are conveniently located on a mask, which are protected from accidental breakage and which do not foul tubing, and a port cap which corresponds to the mask, which is sufficiently large so as to be easy to handle and which is not so small as to be easily lost. SOLUTION: Mask ports 180 for attaching supplemental oxygen supply tubes or measurement devices to a respiratory mask are downward directed and recessed into the base 110 of a mask frame 100. The respective ports comprise a pair of downward extending tubular spigots 185 housed in respective recesses 190 formed in the base 110, with a shallow bridging recess between a pair of the recesses for receiving the bridging piece of a closure cap.
