TUBE DETECTION SYSTEMS AND METHODS

원문 (중국어)

An apparatus may include: processing circuitry; a humidifier configured to humidify breathable gas; an air delivery tube configured to pass the humidified breathable gas to a patient interface, the air delivery tube including a heating element, a sensor configured to measure a property of the breathable gas, and a connector having a plurality of electrical tube contacts at least a portion of which are coupled to the heating element and the sensor; and a contact assembly including a plurality of electrical apparatus contacts configured to electrically couple the plurality of electrical tube contacts to the processing circuitry. The processing circuitry may be configured to determine a type of air delivery tube coupled to the humidifier based on (1) which electrical apparatus contacts are coupled to the heating element and/or the sensor, and/or (2) electrical characteristic measured via one or more electrical apparatus contacts.
