Abdominal cavity hyperthermic perfusion chemotherapy device

Abstract

The invention discloses an abdominal cavity hyperthermic perfusion chemotherapy device which comprises an abdominal pressure belt, an injector assembly and a bed body, wherein the injector assembly and the bed body are installed on the abdominal pressure belt. The injector assembly comprises an injection tube and an infusion tube, the infusion tube is mounted at the top of the injection tube, one side of the injection tube is connected with a liquid return tube, an inlet of the liquid injection tube is connected with a liquid storage tank, an outlet of the liquid return tube is connected with a waste liquid tank, a heating device is arranged on the infusion tube, and a metering pump is arranged on the infusion tube; the bed body comprises an arc-shaped bed board, a bed frame and a support, the arc-shaped bed board is arranged on the bed frame in a sliding mode, an arc-shaped rack is arranged at the bottom of the arc-shaped bed board, a servo motor is arranged on the bed frame, a rotating shaft of the servo motor is connected with a gear meshed with the arc-shaped rack, and the servo motor drives the gear to rotate and drives the arc-shaped bed board to swing back and forth. The bed frame is arranged on the support in a sliding mode, a driving piece is arranged on the support, and the driving piece drives the bed frame to linearly slide on the support in a reciprocating mode. According to the invention, the comfort and the chemotherapy effect of a patient in the chemotherapy process can be improved.

Description

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

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

[0004] In addition, after the heated drug enters the patient's body, it cannot completely fill the patient's abdominal cavity, and the complete contact between the drug solution and the patient's abdominal wall cannot be guaranteed, and the best therapeutic effect cannot be achieved.
