Abstract: A tubing assembly for use with a patient interface device in delivering a flow of breathing gas to an airway of a user is provided. The tubing assembly comprises a manifold portion structured to be disposed generally atop the user's head. The tubing assembly further comprises a plurality of tubular portions. Each tubular portion extends from the manifold portion to a distal end. Each tubular portion is structured to communicate the flow of breathing gas from the manifold portion to the patient interface device. The tubing assembly further comprises at least one adjustment unit configured to adjust a length of a corresponding tubular portion from the plurality of tubular portions. The at least one adjustment unit comprises first and adjustment members that are movable relative to each other, and are selectively and releasably locked to each other at a selected discrete position from a plurality of discrete positions.

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 valve arrangement (60) is for a patient interface device (10) having a frame portion (16). The valve arrangement includes a valve member (36) having a coupling portion (44) and a blocking portion (46) extending from the coupling portion. The coupling portion of the valve member is structured to be coupled to the frame portion. The blocking portion is structured to move between a first position and a second position. The valve arrangement further includes a guard member (40) having a coupling portion (48) and a protecting portion (50) extending from the coupling portion of the guard member. The coupling portion of the guard member is structured to be coupled to the frame portion. When the blocking portion of the valve member moves from the first position toward the second position, the blocking portion moves toward the protecting portion of the guard member.

Abstract: A nasal prong for a cushion member for use with a patient interface device that includes a casing, a flap extending from the casing for insertion into a nostril of a patient, and a bottom cap. The casing and the bottom cap define a space. A fill material is disposed in the space defined by the casing and the bottom cap, wherein the casing is structured to deform and conform to a shape of a portion of the nostril when the nostril applies pressure to the casing.

Abstract: A patient interface device (8) includes a cushion assembly (100) that is customizable to compensate for anatomical variances from patient-to-patient and, therefore, provides an effective seal with the patient's face. The cushion assembly includes a cushion member (102) having a first side structured to engage the patient's face, and a second side disposed opposite the first side, a plurality of plate members (108, 110, 112, 114, 116), and an adjustment mechanism (120, 122, 124). The adjustment mechanism is structured to adjust the position of the plate members, thereby changing the shape of the cushion member to generally conform to the patient's face.

Abstract: A patient interface device for delivering a flow of breathing gas to an airway of a patient, comprises a mask component and auto-adjusting headgear. The auto-adjusting headgear comprises one or more straps wherein the materials have elasticity characteristics such that the headgear self-adjusts. The headgear comprises two lateral strap sections, a rear strap section, and a top strap section. The strap sections are of varying materials and thicknesses to control the properties of the strap sections. In one embodiment, at least a portion of a strap includes a high friction material disposed so as to contact a portion of the user responsive to the headgear being donned by a user.
