A reusable, elastomeric respirator and ventilator, with filter inserts, including a mask body having a pliant facial interface on the interior of the mask body, and two apertures centrally positioned on the front face of the mask body. Two interchangeable plugs or ports are provided to be received within and seal the apertures, deliver oxygen into the mask, or deliver liquids to a wearer of the mask. On opposing sides of the mask body are air filter housings which support an air filter, each air filter housing including a base support structure affixed to the mask body and a top securing structure removably secured to the base support structure. One or more straps are affixed to the mask body to secure the mask body about a wearer's head.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient includes a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the respiratory gas is controlled by a microprocessor, a mixing area for mixing a first gas and a second gas in the respiratory gas flow pathway, a humidification area downstream of the mixing area and configured for humidifying respiratory gas in the respiratory gas flow pathway, and a heated delivery conduit for minimizing condensation of humidified respiratory gas.

A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

Disclosed are methods, systems, and devices for providing a personalized humidification level. A control system receives, from a first sensor, one or more environmental parameters regarding conditions of the environment. The control system receives, from a second sensor, one or more physiological parameters associated with a user within the environment. The control system determines an action associated with a desired change in the humidity within the environment based, at least in part, on the one or more environmental parameters and the one or more physiological parameters. The control system causes, at least in part, a performance of the action associated with the change in the humidity in the environment based, at least in part, on moisture outputted by a humidifier module. The methods and devices perform the same functionality as the control system.

An air conduit for a respiratory therapy device comprises a first end, a second end, and a tube portion, wherein the tube portion comprises a tube wall and an auxiliary structure, such as a rib. The air conduit may deliver a flow of air from a respiratory therapy device or a humidifier to a patient interface. The air conduit may comprise a plurality of auxiliary structures, some of which may consist of a polymeric material, and some of which may comprise a polymeric material and an electrical conductor. An auxiliary structure may be a helical rib extending across a length of the tube portion.

A respiratory therapy system for providing continuous positive air pressure (CPAP) to a patient may include a flow generator for generating a supply of breathable gas, a sensor to measure a physical quantity while the breathable gas is supplied, and a computing device. The computing device may be configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control the flow generator to adjust a property of the supply of breathable gas; display a question and a plurality of selectable responses; receive a first input selecting one of the selectable responses; and display a coaching response corresponding to the selected response.

A connection unit establishes a fluid connection between a patient and a ventilator. The connection unit includes a patient-side connection piece, a device-side connection piece, a port piece and a central piece, which provides a tube with a curved tube segment and is connected with a fluid-tight connection to the two connection pieces. The port piece includes a straight tube segment and a bent surface with a bent surface and with a passage opening. The port piece is inserted into a receiving opening of the central piece. The bent surface of the port piece forms a part of a wall of the curved tube segment. The straight tube segment of the port piece and the central piece provide a straight tube, which is interrupted by the passage opening. An additional device is insertable through the straight tube segment and through the passage opening into the provided tube.

A patient interface includes: a plenum chamber; a seal-forming structure; a positioning and stabilising structure; a plenum chamber insert configured to be positioned and retained within the plenum chamber; and a vent structure; wherein the plenum chamber insert has a plenum chamber insert port; wherein the plenum chamber insert has an exterior surface configured to be positioned adjacent to an interior surface of the plenum chamber; wherein when the plenum chamber insert is positioned and retained within the plenum chamber, a radial channel is formed by the interior surface of the plenum chamber and the exterior surface of the plenum chamber insert such that gas is able to pass between a patient-proximal side of the plenum chamber insert and a patient-distal side of the plenum chamber insert via the radial channel during use.

A device for enclosing a positive end valve (PEEP valve) and converting the PEEP valve to an inline valve for use in a differential multi-ventilation system is described. The device includes a housing configured to enclose the PEEP valve. The housing also includes a ventilator-side arm, a pass-through arm and a patient-side arm. The pass-through arm permits extension of the multi-ventilation system to add one or more patients to the system.
