Breathing tube temperature control circuit and method and breathing auxiliary equipment

Abstract

The invention discloses a breathing tube temperature control circuit and method and breathing assisting equipment, the breathing tube temperature control circuit is used for being connected with a main board, the power supply end of the main board is connected with a heating wire, and the main board is provided with a first control module connected with the breathing tube temperature control circuit; the breathing tube temperature control circuit comprises a detection module and a second control module. The detection module is connected with the second control module and is used for collecting temperature data of the heating wire and transmitting the temperature data to the second control module; the second control module is connected with the first control module and the power supply end of the mainboard, and the second control module is used for transmitting the breathing tube identifier and the temperature data to the first control module; the first control module outputs a heating signal to the second control module according to the breathing tube identifier and the temperature data, and the second control module performs heating control on the heating wire according to the heating signal. According to the invention, the use of circuits between the breathing tube temperature control circuit and the mainboard can be reduced, so that the occupation of interfaces of the mainboard is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a breathing tube temperature control circuit, a method and a breathing assistance device. Background technique [0002] Existing respiratory assistance equipment is usually equipped with a variety of pipelines, and each pipeline has an identification element and a temperature detection circuit. The temperature of the mouth and the air outlet is used to set the breathing working mode accordingly. [0003] However, the identification element in the existing breathing assistance 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 transmission of the pipeline signal are all completed through a separate line, which makes the interface of the main board occupy more . [0004] Therefore, the prior art still needs to be improved and developed. Contents of the inve...
