Hyperthermic intraperitoneal chemotherapy device

Abstract

The invention discloses a hyperthermic intraperitoneal chemotherapy device and relates to the field of medical instruments. The device comprises a Z-shaped abdominal pressure belt, a pressure sensingcomponent and an injector assembly; the injector assembly comprises an injection tube, a double-layer pipeline and an infusion tube, the side wall of the bottom of the injection tube is provided witha plurality of through holes, the outer layer of the double-layer pipeline is connected to a liquid return tube, the outlet of the liquid return tube is connected to the top inlet of the infusion tubesequentially through a waste liquid tank, a liquid storage tank, a heat exchanger and a metering pump to form a chemotherapy liquid circulation loop, and the heat exchanger can ensure the temperatureof a perfusion liquid; the pressure sensing component can sense the pressure change in the abdominal cavity at any time, so that the safety in the chemotherapy process is improved; the Z-shaped abdominal pressure belt can effectively fix the injection tube and prevent the injection tube from falling off in the perfusion process; and the double-layer pipeline is matched with the infusion tube, sothat infusion and export of the perfusion liquid in different layers of the same tube can be effectively realized, only one perfusion tube is needed for needle inserting, secondary needle inserting isnot needed, the comfort level and the chemotherapy effect of a patient in the chemotherapy process are improved, and the practicability is strong.

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
