Abstract: A manufactured component, such as headgear or a headgear strap, for a patient interface for delivery of pressurised air or breathable gas to an entrance of a patient's airways may include a textile portion having a first material with a first melting point. It may also include a plastic portion over-moulded to the textile portion. The plastic portion may be formed of a second material having a second melting point. The melting points may be different such that the second melting point is chosen to be less than the first melting point of the first material. The component may be moulded in a multi-step process that moulds separate portions of the plastic portion and the textile portion at different times. The resulting plastic portion may then have a mechanical bond with the textile and may do so without significant chemical bonding between the plastic portion and the textile.

Abstract: The invention relates to a patient interface comprising a plenum chamber, a seal-forming structure, and a positioning and stabilizing structure, as well as the method of operating the patient interface. The patient's interface is configured to leave a patient's mouth uncovered or if the seal-forming structure is configured to seal around a patient's nose and mouth, the patient interface is configured to allow the patient to breath from the ambient in an absence of the flow of pressurized. The positioning and stabilizing structure includes headgear, and the seal-forming structure and at least a portion of the headgear is formed from a one piece construction of textile material. In another embodiment, the seal-forming structure and/or the positioning and stabilizing structure includes an adaptive portion that adjusts based on usage conditions.

Abstract: A patient interface is configured to deliver a flow of positive pressure respiratory gas to an entrance of a patients airways. The patient interface includes an elastomeric support wall forming at least part of a plenum chamber configured to receive the flow of positive pressure respiratory gas. The patient interface also includes an elastomeric support flange positioned at an end of the elastomeric support wall and extending radially inward from the support wall.
