Abstract: A respiratory interface system for use in delivering a flow of a positive pressure breathing gas to an airway of a patient that includes a patient interface device with a tubing assembly structured to be disposed on the head of the patient, a mask having a sealing element structured to sealingly engage about the airway of the patient, and an adaptor. The adapter includes a flange portion that extends generally radially outward from a central aperture and a hollow male connector extending from the flange portion and coupled with a correspondingly-shaped female connector of the tubing assembly or the mask. The mask is coupled to the tubing assembly via the adaptor, and the tubing assembly, the mask, and the adapter define a pathway structured to conduct the flow of the positive pressure breathing gas to the airway of the patient.

Abstract: A tubing assembly for use with a patient interface device includes a manifold portion structured to be coupled to a conduit carrying a flow of breathing gas and a number of tubular portions. Each tubular portion extends from the manifold portion to a distal end which is structured to be coupled to the patient interface device. Each tubular portion is structured to communicate the flow of breathing gas from the manifold portion to the patient interface device. Each tubular portion comprises an adjustment element which provides for a characteristic of the tubular portion to be selectively varied.

Abstract: A cushion member (10) for a mask structured to be worn on a face of a user. The cushion member includes a cushion portion (12) having a sealing portion (13) and a body portion (14) extending from the sealing portion, the sealing portion being structured to engage the face of the user; and at least one mesh member (22) embedded in at least one of the sealing portion and the body portion.

Abstract: A cushion cover (20) for a patient interface device (8) having a cushion (12) structured to receive a flow of treatment gas. The cushion cover includes a first portion (22) structured to conform to shapes of back surfaces (32) of the cushion and a portion of the side surfaces (34) of the cushion, a second portion (24) structured to conform to shapes of a remainder of the side surfaces of the cushion, and an opening (25) structured to allow treatment gas to pass therethrough, wherein the cushion cover is structured to fit over the cushion.
