摘要：
Elbow assembly including a swivel component (6610) connected to a patient interface (6000) by a pair of spring arms (6650) and coupled to an elbow component (6620) by ball and socket joint and a hinge joint (6645) which allows pivoting about a single axis. Hinge joint prevents the elbow component from contacting the spring arms. Swivel component includes inner radial wall (6630) and outer radial wall (6632) defining radial channel (7633) leading to vent holes (6640) for gas washout, tracks or guide walls (7637) within the channel providing discrete flow paths to the vent holes, an inwardly extending lip or chevron (8631) redirects flow to reduce noise and/or minimize flow directly onto sensitive parts the face. Ball portion (6662) includes opposed recesses (6664) engaged with pivot pins (6645) on swivel component to form the hinge. Elbow component houses a pair of anti-asphyxia valves (6680).
