A face engaging device such as a nozzle, facemask, etc., may include a housing including a fluid channel extending through the housing to an opening configured to be placed in fluid communication with the mouth of a user. The housing may include a first surface configured to be placed in contact with the skin of the user and a second surface exposed to the fluid channel. The face engaging device may also include a thermal actuator supported by the housing and including a first heat transfer surface position on the first surface, where the first heat transfer surface is configured to apply a thermal profile to the skin of the user when the opening is placed in fluid communication with the mouth of the user.

A system provides warm, humidified pas to a patient via a patient interface. Horizontal connections can be used between the humidification chamber and conduit. To reduce the likelihood of condensate flowing back to the humidification chamber, or dead space or gases recirculation regions occurring within the gases flow path, a raised portion is positioned inside of the flow path to improve flow characteristics and to provide a barrier for condensate back flow. The raised portion also reduces the amount of condensate that is formed in the system and provides better flow characteristics for sensing purposes.

A respiratory assistance apparatus includes a conduit connecting a flow generator and an outlet. The conduit includes a venture formation. The apparatus further includes an oxygen inlet in fluid communication or selective fluid communication with an oxygen outlet. The oxygen outlet is directed into the conduit and toward a mouth of the venture formation. The flow generator provides a flow path for air to enter the conduit when the flow generator is not operating.

In accordance with this disclosure, we provide a medical conduit configured to deliver breathable gases in a respiratory therapy system. The medical conduit comprises: i. a first conduit end connector configured to be connected to a user interface; ii. a second conduit end connector configured to be connected to a heated inspiratory conduit; iii. the medical conduit further comprising at least one portion intermediate the first and second conduit end connectors made from a breathable material; iv. the medical conduit being configured to connect the user interface to the heated inspiratory conduit; v. the medical conduit being configured, when connected to the user interface and the heated inspiratory conduit, to be located in an incubator; wherein vi. the medical conduit is unheated. Such a medical conduit can be used in a respiratory therapy system, which comprises an incubator, with the medical conduit inside the incubator.

Provided herein are compositions, methods, uses, and articles of manufacture for iodine treatment on mucosal membranes, and treatment of respiratory pathogens in this way—e.g., by inhalation and combined with the evaporation of steam. In certain embodiments, iodine treatment encompasses administration of compounds that release molecular iodine and/or physiologically active iodine-containing compounds.

Unwinding a portion of a support helix that comprises a heating wire from a wall of a hose at an end of the hose; sleeving a length of heatshrink tubing at least partly onto the unwound portion of the support helix; heating the heatshrink tubing to shrink onto at least part of the unwound portion of the support helix; and at an end of the unwound portion, directly connecting the heating wire to an electrical contact of an electrical connector.

A system includes an electronic circuit, a memory, and a control system. The electronic circuit is coupled to a conduit. The conduit may be configured to deliver pressurized air. A portion of the electronic circuit has a first electrical property that is configured to change based at least in part on movement of the portion of the electronic circuit. The memory stores machine-readable instructions. The control system includes one or more processors configured to execute the machine-readable instructions. Data associated with the first electrical property of the electronic circuit is received. The received data is analyzed. Based at least in part on the analysis, it is determined that the first electrical property of the electronic circuit has changed. Responsive to the determination that the first electrical property of the electronic circuit has changed, it is determined that the conduit is moving or has moved.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.

A patient interface is disclosed that includes: a plenum chamber pressurisable to a therapeutic pressure; a seal-forming structure joined to the plenum chamber and comprising a nasal portion, an oral portion, and at least one hole configured to deliver a flow of air at said therapeutic pressure to at least the patients nares in use, the seal-forming structure constructed and arranged to maintain said therapeutic pressure in the plenum chamber throughout the patients respiratory cycle in use; a vent comprising a plurality of holes configured to allow a continuous vent flow from an interior of the plenum chamber to ambient; a positioning and stabilising structure comprising at least one tie and being configured to hold the seal-forming structure in a therapeutically effective position on the patient's head in use; and a textile portion configured to contact the patients face.

A method includes applying, via a respiratory therapy system, initial therapy settings for a user during a first sleep session in which the user uses the respiratory therapy system. First physiological data, which is received from one or more sensors, is generated during the first sleep session. Modified therapy settings are applied, via the respiratory therapy system, during a second sleep session of the user. Second physiological data is received from the one or more sensors. The second physiological data is generated by the one or more sensors during the second sleep session. A set of sleep-related parameters is determined based on changes between the first physiological data and the second physiological data. One or more of a recommended therapy or recommended therapy settings is determined based on the set of sleep-related parameters.
