A liquid metal peritoneal perfusion and electrochemical treatment device

Abstract

The invention discloses a device adopting intraperitoneal perfusion of liquid metal and electrochemotherapy. The device comprises an intraperitoneal perfusion end, an intraperitoneal extraction end, a positive therapeutic electrode, a negative therapeutic electrode, an external power supply, a temperature control unit, a computer system and a liquid metal infusion bag, wherein the intraperitoneal perfusion end and the intraperitoneal extraction end are connected with the liquid metal infusion bag, and the temperature control unit is arranged outside the liquid metal infusion bag and connected with the computer system; the positive therapeutic electrode and the negative therapeutic electrode are connected with the external power supply, and the external power supply is connected with the computer system. According to the device, thermotherapy of the peritoneal cavity is completed through intraperitoneal perfusion of the liquid metal, the therapy area of the therapeutic electrodes is greatly increased in an electrochemotherapy process, and large-area electrochemotherapy of tumors can be rapidly completed.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a tumor treatment device and its application. Background technique [0002] Tumors are a serious threat to human health. At present, the main methods of treating tumors include surgery, radiotherapy, chemotherapy, thermotherapy and the emerging electrochemical therapy. Surgical operations often have excessive wounds, slow healing, long recovery time for patients, and high risks in surgery. While radiotherapy kills tumor cells, it tends to reduce the patient's own immunity. Chemotherapy has relatively large side effects and is prone to drug resistance. Thermotherapy takes advantage of the difference in temperature tolerance between normal cells and tumor cells to achieve the effect of killing tumor cells without causing damage to normal cells, and can even significantly enhance the immunity of the patient's body. Electrochemical treatment of tumors uses ions in the in...

AI Technical Summary

Problems solved by technology

[0003] However, the current electrochemical treatment problem is that the local pH change only exists in the range of about 2cm around the electrode, but in reality, the size of the tumor often exceeds this value, so the actual treatment situation is According to the size of the tumor, the needles should be arranged reasonably. For the treatment of a 5cm×5cm tumor, about ten treatment electrodes are often inserted to achieve the full therapeutic effect, which adds more extra pain to the patient.
