RESPIRATORY SUPPORT DEVICE HEATING TUBE TEMPERATURE CONTROL SYSTEM AND METHOD, AND RESPIRATORY SUPPORT DEVICE

摘要

A respiratory support device heating tube temperature control system and method, and a respiratory support device. A respiratory support device heating tube temperature control system, comprising: a controller (1), a turbine (2), an ambient temperature sensor (3), a pipeline temperature sensor (4), a heating tube (5), a heating driver (6) and a power supply (7), wherein the turbine (2), the ambient temperature sensor (3), the pipeline temperature sensor (4) and the heating driver (6) are connected to the controller (1); the power supply (7) supplies power to the controller (1), the turbine (2) and the heating driver (6); a heating wire is provided on the heating tube (5), and the heating wire is connected to the heating driver (6); the pipeline temperature sensor (4) is mounted at the tail end of the heating tube (5); and the controller (1) comprises a setting unit. Controlling and adjusting the temperature control power of the entire heating pipeline by means of real-time feedback of the temperature at the tail end of the heating pipeline and the ambient temperature ensures that the air flow blown out from the tail end of a nasal oxygen cannula is warm and humid.
