Abstract

The invention discloses a respiratory tube temperature detection circuit, a temperature detection method and respiration assisting equipment. The respiratory tube temperature detection circuit comprises a detection circuit and an identification circuit; a controller controls a heating wire to heat gas in a respiratory tube; temperature data of a gas inlet end and a gas outlet end of the respiratory tube are detected by the detection circuit and are directly uploaded to the controller or stored into the identification circuit; the identification circuit stores a respiratory tube mark and / or thetemperature data and uploads the respiratory tube mark and / or the temperature data to the controller; and the identification circuit comprises a multiplexing end, and the controller performs power supply or communication on the identification circuit through the multiplexing end in a power supply and communication multiplexing manner. According to the respiratory tube temperature detection circuit, the temperature detection method and the respiration assisting equipment, port merging is achieved through uploading the temperature data and the respiratory tube mark by a power supply end of theidentification circuit in the power supply and communication multiplexing manner, or directly uploading the temperature data and uploading the respiratory tube mark through the multiplexing end of theidentification circuit in the power supply and communication multiplexing manner, and the occupation of interfaces of the controller is reduced.

Description

technical field [0001] The invention relates to the field of breathing assistance equipment, in particular to a breathing tube temperature detection circuit, a temperature detection method and breathing assistance equipment. Background technique [0002] Existing breathing aids (such as ventilators) are usually equipped with a variety of pipelines, each of which has an identification element and a temperature detection circuit. The detection circuit detects the temperature of the air inlet and outlet of the pipeline, and performs a corresponding breathing working mode. [0003] However, the identification element in the pipeline of the existing breathing aid equipment is connected in series with the heating wire in the pipeline, and the temperature detection circuit, the power supply of the identification element and the signal transmission of the pipeline are all completed through a separate line, occupying more interfaces of the controller, resulting in Waste of resources...
