A kind of intraperitoneal hyperthermic perfusion chemotherapy device

Abstract

The invention discloses an intraperitoneal hyperthermic perfusion chemotherapy device, which relates to the field of medical equipment and includes a Z-shaped abdominal pressure belt, a pressure sensing part and a syringe assembly; the syringe assembly includes an injection tube, a double-layer pipeline and an infusion tube, and the bottom side wall of the injection tube is arranged There are several through holes, and the outer layer of the double-layer pipeline is connected with a liquid return pipe, and the outlet of the liquid return pipe is connected with the top inlet of the infusion pipe through the waste liquid tank, the liquid storage tank, the heat exchanger and the metering pump in turn to form a chemotherapy liquid circulation loop The heat exchanger can ensure the temperature of the perfusate; the pressure sensing part can sense the pressure change inside the abdominal cavity at any time, which is conducive to improving the safety during chemotherapy; the Z-shaped abdominal pressure belt can effectively fix the injection tube and prevent it from falling off during the perfusion process; the double-layer pipeline With the infusion tube, it can effectively realize the infusion and export of the perfusion fluid in different layers of the same tube. Only one perfusion tube can be used to insert the needle, and there is no need for a second needle insertion, which is conducive to improving the comfort and chemotherapy effect of patients during chemotherapy. Strong practicality.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intraperitoneal hyperthermic perfusion chemotherapy device. Background technique [0002] Intraperitoneal chemotherapy is a kind of chemotherapy method, which is mainly to infuse chemotherapy drugs into the abdominal cavity to make the chemotherapy drugs in the abdominal cavity reach a certain concentration, so as to play an anti-cancer effect. In clinical practice, the perfusion liquid and chemotherapeutic drugs at around 45°C are mainly infused into the peritoneal cavity, and the thermal effect of the perfusate is used to kill the tumor and the synergistic effect of the thermal effect and chemotherapeutic drugs is used to enhance the sensitivity of tumor cells. , and then promote the rapid apoptosis of tumors, and finally achieve the purpose of preventing and treating peritoneal metastasis of tumor cells. [0003] At present, the existing peritoneal hyperthermic perfusion dev...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing peritoneal hyperthermic perfusion devices focus on how to ensure that the perfusion temperature of the perfusate reaches the standard. However, due to the flow of the perfusate during perfusion chemotherapy, it is easy to cause the structure such as the injection needle or the injection tube to fall off from the skin, which will not only cause a large Cause a large amount of injection liquid leakage, affect the perfusion effect, and it is likely to require a second needle insertion for the patient

In addition, after the peritoneal perfusion is completed, the perfusion fluid needs to be exported again. Currently, the perfusion hole and the outlet hole are inserted separately. If the above-mentioned problem of shedding occurs, the patient will be inserted multiple times, causing the patient's treatment pain. , reducing patient comfort and increasing the workload of medical staff
