摘要:
A respiratory mask includes a mask shell defining an interior of the respiratory mask and a gas washout vent passage having an inlet forming part of the mask shell and in fluid communication with the interior and an outlet in fluid communication with atmosphere. The mask shell includes a tubular mask inlet adapted to connect to a breathable gas supply conduit. The outlet includes an interior surface that forms a smooth prolongation with an adjacent exterior surface of the mask shell, and the outlet is adapted to direct washout gas in a direction substantially parallel to a longitudinal axis of the mask inlet and away from the mask inlet. The mask shell includes a body portion and a cap portion.
