The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swivelled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface. The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.

The invention claimed is: 1. A patient interface for use as part of a system for delivering a supply of gases to a patient comprising:a hollow body adapted to locate onto the face of a user in use, said hollow body including an aperture passing from the inside of said body to the outside,an elbow connector that connects between said aperture and said supply of gases, so that in use the inside of said body is in fluid communication with said supply of gases through said elbow connector,said elbow connector including a funnel located within said elbow connector, and as least one outlet bias hole, said funnel adapted so that in use a substantial portion of gases expired from said patient pass through said funnel and pass out of said patient interface through said at least one outlet bias hole, said funnel extending within said elbow connector and shielding said at least one outlet bias hole from gases supplied to said patient by said supply of gases,said elbow connector further having a flexible duct portion on the exterior surface of said elbow connector over and around said at least one outlet bias hole, at least one outlet vent hole formed in said flexible duct portion.
