A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways includes a frame member, a cushion assembly provided to the frame member, and an anterior wall member repeatedly engageable with and disengageable from the cushion assembly. The frame member includes connectors operatively attachable to a positioning and stabilizing structure. The cushion assembly includes a seal-forming structure and a void defined by an anterior surface of the cushion assembly. The anterior wall member has a predetermined surface area to seal the void of the cushion assembly and form a gas chamber when the anterior wall member and the cushion assembly are engaged. The void of the cushion assembly is sized such that the patient's nose and/or mouth is substantially exposed when the anterior wall member is disengaged from the cushion assembly thereby improving breathing comfort of the patient.

The present invention relates to a gas conduit for a respiratory support device comprising a face mask and a gas reservoir bag, said gas conduit comprising a proximal portion for fluid connection to the mask and a distal portion extending into the reservoir bag, wherein at least a side wall of said distal portion comprises one or more apertures. The present invention also relates to a respiratory support device comprising said conduit.

An apparatus for acoustically detecting the location of a distal end of a tube relative to a body conduit into which the tube is being inserted is provided. The apparatus including a speaker positioned to generate a sound pulse in the tube and a sensor for detecting a sound pulse in the tube at a distal position relative to the speaker, and for generating a signal corresponding to the detected sound pulse.

An assembly for conducting respiratory air in a patient ventilation system has a plastic respiratory air tube component for conducting respiratory air. At least one heating wire is used to heat the respiratory air. A plastic connector conducts the respiratory air, is integrally connected to an end portion of the tube component and is used for connection to a further, external respiratory air-conducting component. The connector has a connection piece in which an end portion of the heating wire is electrically contacted to an external supply line. The end portion of the heating wire is routed through a lateral wall of the connector to the connection piece. In the connection piece, a recess for accommodating a protective plastic housing for an electrical contacting portion is provided between the heating wire end section and the end portion of the supply line.

The present invention relates to an apparatus for providing respiratory assistance to a user via a user conduit. The apparatus being operable in a humidifying mode and a non-humidifying mode, and includes a humidification chamber for containing an amount of water that can be located in an operating position in the humidifying mode and, optionally separate from the apparatus in the non-humidifying mode. The apparatus may also have an auxiliary flow path that can be activated in the non-humidifying mode and a powered device that heats water in the humidification chamber when the apparatus is in the humidifying mode.

The present technology relates to a patient interface for delivery of a flow of pressurised air to an entrance of a patient's airways, the patient interface comprising a mask with a seal-forming structure and one or more positioning and stabilising structures configured to provide a force to hold the mask in a therapeutically effective position on a patient's head in use. The mask and one or more of the positioning and stabilising structures includes a connection port to receive an end of the air circuit. The pressurised air is delivered from the air circuit to the seal-forming structure. In use, the patient connects the air circuit to the connection port of choice, depending on whether they prefer the patient interface to be arranged such that the end of the air circuit is superior to the patient's otobasion superior or inferior to the patient's otobasion superior.

The present invention provides a particulate delivery device with an automatic activation mechanism that pierces or cuts a composition capsule when a cap is removed. The cap cannot be replaced once the device is activated for use. The device allows for gas flow through the device from a gas inlet to a gas outlet through a composition receptacle and dispersion chamber to deliver particulate to the airway of a subject.

An illustrated view of a non-kinking air hose for preventing an air hose from kinking is presented. The non-kinking air hose is useful for providing an air flow from an air tank to a patient where the air hose is prevented from forming a kinking condition. The non-kinking air hose further prevents damage or reduced/zero air flow from an air tank to a patient.

A patient interface device includes a frame member and a cushion having a main body, a sealing portion, and first and second posts extending from the main body. The frame member defines a first orifice and a second orifice. The first post of the cushion is rotatably received within the first orifice and the second post is rotatably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member.
