ABSTRACT:
A mask apparatus for use in a breathing assistance system may include a ball joint at least partially defined by a housing, a ball member, and a mounting system. The housing may be configured to support a cushion configured to provide a seal against a patient's face. The housing may include a first side defining a first housing opening, and a second side configured to face the cushion and defining a second housing opening. The ball member may be positioned in the first housing opening and may define a ball member opening configured for communicating gas though the first housing opening. The mounting system may be configured to secure the ball member in the first housing opening such that the housing, the ball member, and the mounting system define a ball joint allowing the ball member to rotate about multiple axes relative to the housing and the mounting system.
