摘要： 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.

摘要： A gas washout vent for a patient interface may be configured to allow a flow of patient exhaled gas to an exterior of the patient interface to minimise rebreathing of exhaled gas by the patient and the vent may include: a plurality of vent passages extending between a first and a second side of the vent, each vent passage may include: a plurality of first openings extending from the first side towards the second side, said first openings being uniform in size and shape; a plurality of second openings extending from the second side towards the first side, said second openings being uniform in size and shape; and wherein the first openings and the second openings partially overlap each other at an interface to form constricted passages therebetween.
