ELBOW CONNECTOR FOR RESPIRATORY SYSTEM

摘要

ELBOW CONNECTOR FOR RESPIRATORY SYSTEM An elbow assembly is configured to connect a mask assembly to an air conduit. The elbow assembly comprises an elbow and a sleeve. The elbow comprises inner and outer walls and 5 defining an air venting channel therebetween. The inner wall defines a flow channel through the elbow, the inner wall comprising a port. The sleeve is coupled with the elbow. The assembly also comprises a flap. When the flap is at a first position the flap at least partially blocks the port and allows gas from the air conduit to pass to a user via the flow channel through the elbow. When the flap is at a second position, the flap at least partially blocks the 10 flow channel thereby allowing gas to flow from the user to a location outside of the elbow assembly via the port and the air venting channel. The air venting channel directs air away from the user. -50- XO 2012/140514 PCT/B20I /00085--8
