Elbow for mask system
View Patent ↗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.
1. An elbow for use with a mask assembly, comprising:
a proximal end adapted to be provided to the mask assembly;
a distal end adapted to be provided to an air delivery conduit,
the proximal end including a generally cylindrical portion and a baffle provided within the cylindrical portion, the baffle defining an intake port configured to direct incoming air from the air delivery conduit into a mask cavity of the mask assembly and an exhaust port separated from the intake port and configured to direct exhaust air from the mask cavity to atmosphere,
wherein the baffle includes an end portion that protrudes beyond the cylindrical portion, and the end portion having an arcuate configuration in plan view such that a curvature of the end portion begins and ends at intersection points at which the end portion protrudes beyond the cylindrical portion.
2. The elbow according to claim 1 , wherein the end portion is adapted to extend into the mask cavity which is defined by the mask assembly.
3. The elbow according to claim 1 , wherein the baffle has a generally planar configuration.
4. The elbow according to claim 1 , wherein the end portion has an arcuate configuration in plan view to avoid sharp edges that may contact a patient's face.
