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 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: The present disclosure relates to a liquid electrophotographic ink developer unit. The unit comprises a developer roller comprising a layer formed from a polymer composition containing a conductive filler, whereby the polymer composition has a specific resistivity of less than 1×106 ?·cm. The unit also comprises a secondary roller that co-operates with the developer roller.

Abstract: A patient interface system includes a patient interface device, a conduit coupled to the patient interface device, and a gas supply assembly. The gas supply assembly includes a body portion having a first end, a second end disposed opposite and distal from the first end, a lower segment, and an upper segment attached to the lower segment. The first end includes a first coupling portion coupled to the patient interface device. The second end includes a second coupling portion coupled to the conduit. The upper segment and the lower segment together form an air channel extending between the first coupling portion and the second coupling portion. The first end is configured to be substantially disposed on the patient's forehead. The second end is configured to position the conduit away from the patient's face.

Abstract: A respiratory interface device is provided. The respiratory interface device includes a mask (10) having a faceplate (12) and a patient contacting cushion (15), the patient contacting cushion coupled to, and extending about, the faceplate, a brace assembly (40) having a brace body (42) with at least one mask coupling, the mask and the brace assembly coupled at the mask coupling, wherein the mask coupling is a soft coupling. The mask soft coupling utilizes a flexible membrane assembly, the flexible membrane assembly being disposed between the mask and the brace body.

Abstract: An improved patient interface (4) having a cushion (12) and a headgear (16), with the headgear having a pair of engagement elements (24) that each engage the patient with an engagement force, and with the engagement forces being directed generally toward one another. The engagement forces result in frictional forces between the headgear and the patient which resist the cushion from becoming disengaged with the patient. In one embodiment, the engagement elements each include a circumferential brace (44) that engages the head and extends about the ears. In another embodiment, the engagement elements engage the ears of the patient. In a free state, at least a portion of the headgear is of a spiral configuration which makes the patient interface collapsible and relatively easy to pack, such as for traveling.
