Abstract: A patient interface includes a cushioning structure including at least one hollow chamber filled with first and second discrete and/or layered filling materials and a seal forming structure formed in one piece with the cushioning structure. The seal forming structure includes a thin membrane flap that is structured to provide a seal to the patient's face. The chamber extends only around a portion of the perimeter of the cushioning structure such that the chamber with first and second filling materials is provided in cheek and lip regions of the cushioning structure and a solid silicone portion is provided in a nasal bridge region of the cushioning structure.

Abstract: A respiratory mask includes a frame and a flexible structure provided to the frame and adapted to engage a patient's face. The flexible structure includes a chamber filled with a first gel and a second gel that is relatively harder than the first gel. A ratio of height of the first gel to the second gel in a lip region is in the range of about 0.25 to about 0.6.

Abstract: A patient interface that provides breathable gas to a person has a face engaging cushion that includes an internal cavity. In the internal cavity fluid is located, and a control means that is capable of communicating with the fluid can incite change to a property or to properties of the fluid.

Abstract: Component of a patient interface (1), particularly a cushion, comprising a first portion (3) having a first shore hardness and a second portion (5) having a second shore hardness different from the first shore hardness, wherein the first and second portion are co-molded to each other.

Abstract: The present technology relates to a tub for a humidifier comprising a container made of a first material, a heating element, and a lining made of a second, preferably biocompatible, material different from the first material, wherein the container comprises a base and a side wall defining a reservoir for a supply of liquid to be evaporated, the heating element is provided on the base of the container, and the lining covers the heating element and a substantial portion of the inner surface of the side wall of the container.

Abstract: A hollow structure for a face mask includes an inner wall, an outer wall spaced from the inner wall to define a hollow area between the inner wall and the outer wall, and a bottom wall that couples the inner wall to the outer wall. A first portion and a second portion together define a closable opening into the hollow area. The second portion is coupled to the outer wall by a bi-stable membrane that allows the second portion to move between (1) a first, opened position in which the second portion is spaced from the first portion to allow access to the hollow area through the opening, and (2) a second, closed position in which the second position abuts the first portion to close the opening.

Abstract: A method for producing a filled hollow structure includes producing an open hollow structure of a first material, positioning the open hollow structure on a tool adapted to hold the open hollow structure, filling the open hollow structure with a filler medium, and closing the filled open hollow structure with a second material. A hollow structure may be produced by such method, and a tool may be structured to perform such method.

Abstract: The present technology relates to a kit comprising a device for providing breathing gas to a patient and a specific facing as well as to a method of setting the mode of operation of such a device.

Abstract: The present invention relates to the surface structure of a plastic material and particularly of silicone surfaces. More particularly, the present invention relates to the surface structure of the surfaces of a breathing mask assembly or a patient interface to be used for supplying breathing gas to a patient. Such patient interface for providing respiratory gas to a patient comprises a contact surface for contacting a patient's skin, wherein at least a part of said contact surface is a structured surface.

Abstract: The present invention provides a method for producing a filled hollow structure, preferably a cushion for a breathing mask. According to said method, a hollow structure of a first material having a cavity is produced, wherein the hollow structure has an inlet to and an outlet from the cavity. The hollow structure is positioned on a tool for holding the hollow structure. Subsequently a second material is inserted through the inlet into the cavity, while gas present in the cavity can escape through the outlet. Finally, the inlet and/or the outlet is sealed. During the step of inserting the second material through the inlet into the cavity the outlet resists flow of said second material.

Abstract: The present invention relates to a patient interface comprising a member for contacting the skin of a patient during use, wherein at least a part of said member comprises a substance, wherein the substance is released to the patient's skin during use.

Abstract: The present invention relates to the surface structure of a plastic material and particularly of silicone surfaces. More particularly, the present invention relates to the surface structure of the surfaces of a breathing mask assembly or a patient interface to be used for supplying breathing gas to a patient. Such patient interface for providing respiratory gas to a patient comprises a contact surface for contacting a patient's skin, wherein at least a part of said contact surface is a structured surface.

Abstract: The invention relates to a patient ventilation or breathing device and components therefore for use in all forms of respiratory apparatus ventilation systems including invasive and non-invasive ventilation, positive airway pressure therapy, Continuous Positive Airway Pressure (CPAP), and particularly Bi-Level therapy and treatment for sleep disordered breathing (SDB) conditions such as Obstructive Sleep Apnea (OSA), and for various other respiratory disorders and diseases. The invention particularly relates to a blower, to a blade, to a gasket, to a cable, to an impeller, to a gas inlet and inlet member, to an improved air path or fluid flow path and components thereof, and/or to a modular ventilation or breathing device as referred to above and particularly incorporating one or more of the other aspects of the invention.

Abstract: The present invention is related to a cushion (1) for a respiratory mask, to a method of manufacturing such a cushion (1) as well as to a respiratory mask including a cushion (1) and an apparatus for manufacturing a cushion (1) for a respiratory mask. It is particularly referred to a method of manufacturing a cushion (1) for a respiratory mask, comprising the steps of providing a mold comprising at least two mold halves (11, 13) and at least one core (12) therein, closing the mold, injecting a first material into the mold to form the cushion (1), wherein the core (12) is enclosed by the cushion (1) thereby forming at least one cavity (4), opening the mold, removing the core (12) from the cushion (1) to provide the at least one cavity within the cushion (1), and sealing the cavity (4).

Abstract: A cushion assembly for use with a respiratory mask includes a bladder filled with the combination of a gel having a first indentation hardness and a gel having a second indentation hardness.
