If the circulation is adopted, the heat productivity of the field effect tube can be automatically adjusted, thereby achieving the purpose of automatically controlling the heating temperature. In addition, the temperature control module can also realize the accurate adjustment of the heating temperature.

Wherein, the field effect tube heater 101 is arranged on the fixing device 102; the fixing device 102 is fixed on the tube wall of the infusion tube 100, so that the infusion tube 100 is attached to the field effect tube heater 101; the power supply mechanism 103 is connected to the fet heater 101 for supplying power to the fet heater 101.
The fet heater 101 is a heater that operates by self-heating when the fet is energized, and has a fet as a heating element.
In this embodiment, the structure of the fet heater 101 may be as shown in fig. 1b, and includes: a field effect transistor 1011 as a heating element and a temperature control module 1012 connected to the field effect transistor 1011; the temperature control module 1012 controls the working current of the field effect transistor 1012 according to a preset temperature, and when the working current is higher than the preset temperature, the working current of the field effect transistor 1011 is reduced, so that the heat productivity of the field effect transistor 1011 is reduced, and when the temperature is lower than the preset temperature, the working current of the field effect transistor 1011 is increased, so that the heat productivity of the field effect transistor 1012 is increased, and the heating temperature is automatically controlled. The temperature control module 1012 can set the value of the preset temperature, so that the heating temperature can be accurately adjusted.
In practice, the temperature control module 1012 may employ a thermistor. When the temperature is higher than the preset temperature, the resistance value of the thermistor changes, so that the internal resistance of the field effect tube heater 101 is increased, the working current of the field effect tube 1011 can be reduced, and when the temperature is lower than the preset temperature, the resistance value of the thermistor changes, so that the internal resistance of the field effect tube heater 101 is reduced, the working current of the field effect tube 1011 is increased, and the temperature control of the field effect tube 1011 is realized. It should be noted that, the present invention is not limited to specific components and circuits adopted by the temperature control module 1012, and any circuit and components capable of implementing the above functions may be adopted by the temperature control module 1012 according to actual needs.
The number of the field-effect transistors 1011 may be one or plural. When only one field effect transistor is adopted, the field effect transistor with the maximum working voltage larger than 15V and the maximum working current larger than 2A can be selected.

The length of the groove 1021 can be designed according to the length of the infusion tube 100 to be heated. In practical application, one end of the infusion tube 100 needs to be connected with the liquid medicine bottle, and the other end needs to be connected with the injection needle, so that the heating device can be fixed in the middle of the infusion tube 100 and only heats one section of the middle of the infusion tube 100. The groove 1021 can be designed into a linear type, or a spiral type, an S type and other curved types, so as to save space and increase the heating length of the infusion tube 100. In this embodiment, the fet heater 101 is mounted adjacent to the groove 1021, and the heat-conducting sheet 1013 may be attached to the sidewall of the groove 1021, so that the heat-conducting sheet 1013 and the infusion tube 100 can be tightly attached.
In order to improve the efficiency of the warming apparatus, the infusion tube liquid medicine warming apparatus of the present embodiment is further provided with a heat insulating apparatus 104. The heat preservation device 104 is mounted on the fixing device 102 and used for preserving heat of the field effect tube heater 101.
