Fig. 1 is a schematic view of a tumor local thermal chemotherapy apparatus 100 according to the present application, as shown in fig. 1. The tumor local thermal chemotherapy device 100 comprises: a medicine filling table 101, a medicine storage bottle 102, an infusion tube 103, a first transmission line 104, a second transmission line 105, a circuit switch 106, a power supply 107, an injection needle 108 and a first annular metal plate 109;
the medicine storage bottle 102 is arranged on the medicine filling platform 101, and the mouth of the medicine storage bottle 102 is communicated with the infusion tube 103. Optionally, as shown in fig. 1, a hanging rod 110 is fixedly arranged on the drug infusion table 101; the drug storage vial 102 is hung on a hanging bar 110. As shown in fig. 2 or 3, the infusion tube 103 is provided at its distal end with an injection needle 108.
The first power line 104 and the second power line 105 are electrically connected with the positive electrode and the negative electrode of the power supply 107 respectively; the positive pole or the negative pole is provided with a circuit switch 106. As shown in fig. 1, the circuit switch may be provided on a positive circuit, or may be provided on a negative circuit.
The first power line 104 is wound around the infusion tube 103 to form a power transmission coil, the end of the first power line 104 is electrically connected to the first annular metal plate 109, and the first annular metal plate 109 is adhered to the infusion tube 109.
