(EN) SENSING FOR RESPIRATORY CIRCUITS
(FR) DÉTECTION DE CIRCUITS RESPIRATOIRES
Abstract
(EN)
Some embodiments provide a breathing assistance apparatus comprising a conduit for conveying gases therein, the conduit comprising circuitry. The circuitry may comprise at least one heater wire part to heat gases in the conduit, in use, and at least one sensor wire part comprising at least one sensor for monitoring a parameter of the gases in the conduit. There is also provided a controller to control provision of AC power or AC voltage to the heater wire part; and control selective reading of the sensor. The controller may be configured to read the sensor at or about a particular portion of the AC power waveform provided to the heater wire part.

Certains modes de réalisation concernent un appareil d'assistance respiratoire comprenant un conduit pour transporter des gaz à l'intérieur de celui-ci, le conduit comprenant des circuits. Les circuits peuvent comprendre au moins une partie fil chauffant pour chauffer les gaz dans le conduit, durant l'utilisation, et au moins une partie fil de capteur comprenant au moins un capteur pour surveiller un paramètre des gaz dans le conduit. L'invention concerne également un dispositif de commande pour commander la fourniture d'une alimentation en courant alternatif ou d'une tension alternative à la partie fil de chauffage ; et pour commander la lecture sélective du capteur. Le dispositif de commande peut être conçu pour lire le capteur au niveau ou autour d'une partie particulière de la forme d'onde de l'alimentation en courant alternatif fournie à la partie fil chauffant
