NZ605941A - Elbow for mask assembly - Google Patents

Abstract

An elbow assembly for a respiratory mask comprising an elbow (160), the elbow including: a) a first end portion (166) including a surface adapted to engage a surface of a gas delivery tube; and b) a second end portion provided to the mask. The elbow further defines: i) an inlet port (162) to deliver incoming gas in a first direction to a nasal breathing cavity defined by the mask, and ii) an exhaust port (164) separated from the inlet port by at least one baffle (161). The baffle directs the incoming gas to tum into the nasal breathing cavity, and the baffle is configured to direct exhaust gas away from the nasal breathing cavity in a substantially linear direction through the exhaust port into a vent cavity. The baffle extends beyond the second end portion.
