A method includes forming an antimicrobial blend including an antimicrobial additive combined with a polymer, and forming a medical device with the antimicrobial blend, wherein a surface of the medical device exhibits antimicrobial properties.

A mask system for delivery of respiratory therapy to a patient includes a nares portion and a mouth portion and an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver the pressurized, breathable gas. The mask system is adapted to selectively utilize the nares portion and/or the mouth portion in a first mode utilizing both the nares portion and the mouth portion, and in a second mode utilizing the nares portion and not utilizing the mouth portion.

A patient interface with a sealing device, the sealing device comprising a support membrane and a sealing membrane. The sealing membrane is designed at least in part to bear on the skin of a patient and the support membrane extends at least in part adjacent to the sealing membrane. The distance between the support membrane and the sealing membrane is at least in part such that an interspace is formed.

Forehead support adjuster for a mask, wherein the forehead support adjuster comprises at least a forehead support, consisting of support arm and cushion holder, a connection element, a rail with at least one guide groove, and a slide element, and wherein the slide element has at least one slide plate, at least one tenon and a guide element, wherein the at least one tenon is mounted rotatably and slidably in the at least one guide groove of the rail, and wherein the slide element is movably connected to the support arm. The forehead support adjuster is configured such that a movement of the slide element along the rail leads to a pivoting of the forehead support about at least one pivot axis D.

Respiratory mask with a face part which comprises at least one plane of symmetry, a circumferential seal and an outlet, wherein the face part has an outer side with at least two anchor points, which are arranged to both sides of the plane of symmetry, and wherein the at least two anchor points each comprise a receiving element for releasable connection to a connection element, and wherein the connection element is configured to receive a harness. At least one guide region is arranged adjacent to the receiving element.

A cushion support assembly for a respiratory interface device cushion is provided. The cushion support assembly includes a cushion support assembly ribbon-like body with an inner side, an outer side and a wide facial side. The cushion support assembly body facial side includes a support surface, the support surface is structured to support the respiratory interface device cushion engagement portion in a generally planar configuration. The cushion support assembly body facial side support surface is generally planar relative to the user's respiratory interface device contour radial aspect.

Disclosed is a spring element which is suitable for use with a patient interface and in the form of an elongated body and has an axis along which the spring element is compressed. Arranged in a direction of the axis, the spring element comprises a first region and a second region, at least one characteristic of the spring element in the first region having a value which is different from a value of the at least one characteristic in the second region.

The invention provides a patient interface (10) comprising a patient interface element (12, 14, 15) for delivering breathing gas to a patient, and a forehead support (30). One of the forehead support and the patient interface element comprises a shaft (50) and the other comprises a hollow tube (51) in which the shaft is received, with the shaft slidable within the tube to permit adjustment of the position of the forehead support relative to the patient interface. The shaft and hollow tube are rotatable between a free and locked configuration. This provides a simple to use adjustment mechanism with few components.

A patient interface device (10) includes a patient sealing assembly (60) including a cushion (70), and a frame member (80) coupled to the cushion, and an adjustable forehead support assembly (200) provided at the distal end (120) of the frame member. The adjustable forehead support assembly includes an adjustment mechanism (202) coupled to a forehead cushion (204), wherein the adjustment mechanism includes a forehead cushion support member (212) having a base portion (216) coupled to the forehead cushion and an vertical/upright rotatable wheel member (214). Rotation of the wheel member causes movement of the frame member and the cushion relative to the forehead cushion.

The invention provides a patient interface (10) comprising a patient interface element (12, 14, 15) for delivering a breathing gas to a user and a forehead support (30). One of the forehead support and the patient interface element comprises a shaft (60) and the other comprises a hollow tube (62) in which the shaft is received, with the shaft slidable within the tube to permit adjustment of the position of the forehead support relative to the patient interface element. One of the shaft and hollow tube are elastically deformable between a deformed configuration in which the shaft can be slid within the tube and a released configuration in which the sliding of the shaft within the tube is blocked.
