摘要:
A swivel elbow for a mask assembly includes an elbow adapted to be provided to the mask assembly and a swivel detachably connected to the elbow. The elbow includes a plurality of spaced apart rings that provide a controlled clearance between the elbow and an interior surface of the swivel.
摘要:
A breathing assistance device includes a gas regulating valve (1300). The gas regulating valve is operated by a linear actuator (1330). The linear actuator may include a movable member that moves an obstruction member between an open position and a closed position. The linear actuator is isolated from a gas flow path through the valve.
摘要:
A mask cushion or a mask assembly therewith provides a comfortable and effective seal for provision of a gas therapy by a respiratory treatment apparatus. The mask cushion (102) may be integrated with or coupled to a mask frame. The mask cushion typically includes an inner cushion component (104). The mask cushion also includes a patient facial-contact side portion with a chamber (108) and a barrier (106) to form the chamber that may be flexible. The chamber may serve as an outer layer with respect to the inner cushion component. The chamber may be partially or completely filled with a gas, fluid or gel. The inner cushion may be formed with a soft flexible material such as an elastomer or foam, etc. The barrier may be a membrane and may also be soft flexible material.

摘要:
An elbow for a mask system includes a proximal end adapted to be provided to the mask system, a distal end adapted to be provided to an air delivery conduit, and a baffle provided within the proximal end. The baffle has a generally planar configuration that defines an intake port that directs incoming air from the air delivery conduit into a mask cavity and an exhaust port separated from the intake port that directs exhaust air from the mask cavity to atmosphere. The baffle includes an end portion that is adapted to extend into the mask cavity defined by the mask system.
