Background Thermal infusion is a new way of tumor treatment by hyperthermia fusion chemotherapy. The method is characterized in that a catheter is placed into a human body by utilizing puncture or minimally invasive surgery, therapeutic liquid medicine is heated by a hot filling device and then is input into the human body through the catheter, the liquid medicine flows in the human body to effectively kill tumor cells, and then the liquid medicine returns to the hot filling device through another catheter, so that the liquid medicine is circulated. The hot perfusion device realizes the functions of heating the liquid medicine and circulating the liquid medicine. The existing hot-fill apparatus includes a main machine and a hot-fill line (liquid circulator). The main parts of the host are a heater at a, a heating circulating pump at b and an output pump at c in fig. 1, wherein the heating circulating pump and the output pump are all pumps which generate attractive force through a squeezing and releasing pipeline. The main components of the hot filling pipeline are a liquid bag at d, a heating pipeline at e, an output pipe at f and a return pipe at g in fig. 1. The liquid bag is hung on the host machine, and the liquid medicine is put into the liquid bag through the hanging infusion bag. The liquid medicine heating mode is that the heating pipeline is wound around the heating circulating pump, the heating pipeline is provided with a U-shaped hard pipe, the U-shaped hard pipe is inserted into the heater, the liquid medicine in the liquid bag circulates in the heating pipeline and the liquid bag under the action of the heating circulating pump, and the heater heats the liquid medicine passing through the U-shaped hard pipe, so that the liquid medicine in the liquid bag keeps proper temperature. In addition, a temperature measuring device is additionally arranged to measure the temperature of the liquid medicine input into the human body, and the heating temperature of the heater is further controlled through the measured value. The liquid medicine is fed into human body through the output pipe, which is wound around the output pump and connected to the catheter inside the human body.
