Abstract: A headgear for use with a patient interface for providing a flow of pressurized breathing gas to the airway of a patient includes a pair of wrapping panels positioned at a rear thereof. The wrapping panels prevent the tension in the neck of a patient that commonly results when non-wrapping headgear is tightened.

Abstract: A minimal weight patient interface device that delivers breathing gas to a user includes a cushion assembling including a support cushion assembly and a sealing member is described herein. In one exemplary embodiment, the support cushion assembly includes a wedge that is made of a high density foam received within a wedge receiving portion of the support cushion assembly. In the exemplary embodiment, the cushion assembly is formed by the sealing member fitting over the support cushion assembly. The sealing member, in one embodiment, is made of silicone, for example, having a low durometer value (e.g., between 5-10 Shore 00). Furthermore, in one embodiment, the patient interface device also includes a faceplate that is placed over the cushion assembly and is made of a thermoform, such as a high density foam laminated between two pieces of fabric, such as polyester.

Abstract: An elongated flexible conduit (4) includes an flow element (24) having a first elongated wall segment (32) and a second elongated wall segment (44) that are connected together at their sides to form a wall (28) that is continuous in a circumferential direction perpendicular to the direction of elongation (8). The flow element is movable between a first configuration and a second configuration (68), with the first configuration being an expanded configuration, and with the second configuration being a collapsed configuration. The flow element can be moved from its expanded configuration to its collapsed configuration, such as for purposes of packing during traveling, and can then be moved from its collapsed configuration back to its expanded configuration in any of a variety of fashions in order to return the flow element to a condition in which it can carry a flow of breathing gas from a CPAP machine (12) to a CPAP mask (16).
