CUSHION FOR PATIENT INTERFACE WITH LOCALIZED REGION OF REDUCED STIFFNESS

摘要

An improved resilient cushion of a patient interface is structured to engage the face of a patient and includes a deformable bellows portion having a pair of deformable elements. One of the deformable elements has an indentation formed therein that provides a localized region of reduced stiffness and which results in an improved fit on the face of the patient.
