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.

METHODS AND APPARATUS FOR CONTROL OF OXYGEN CONCENTRATOR
20220379066 · 2022-12-01 · ·

Methods and apparatus provide controlled operations in an oxygen concentrator (100) such as by adjusting valve opening time to regulate amount of oxygen enriched air released to a user. The apparatus may generate, with a sensor configured to sense pressure at a location associated with accumulation of enriched air produced by the concentrator, a signal representing measured pressure of the accumulated enriched air. The apparatus may generate, with a sensor, a signal indicative of respiration of a user of the concentrator. The apparatus may include a controller configured to receive the measured pressure and respiration signals. The controller may control, responsive to the respiration indication and according to a target duration, actuation of a valve adapted to release a bolus of accumulated oxygen enriched air. The controller may dynamically determine the target duration during the release of the bolus according to a function of a value of the measured pressure.
