Intraperitoneal hyperthermic chemotherapy circulation circuit device

Abstract

The invention provides a chemohyperthermia circulation pipeline device for intraperitoneal chemohyperthermia. The circulation pipeline device is adjusted to adapt to different therapy periods by on and off of clips to meet requirements of the intraperitoneal chemohyperthermia. System simplicity and reliability can be achieved while liquid medicine is undamaged by using heating plates for heating. Using a temperature tee joint is convenient for arrangement of temperature detection points and can guarantee precision in temperature detection and control so as to guarantee therapeutic effects of the intraperitoneal chemohyperthermia. Using a liquid collection bag is convenient for infusion of liquid medicine and convenient to operate, and air is prevented from being mixed in the liquid medicine during circulation, so that therapeutic effects can be guaranteed. The liquid medicine is completely recovered to the liquid collection bag after therapy, and leakage and environment pollution are prevented. Pump pipes are arranged on two sides of a heating bag to avoid inflation of the heating bag. Human tissue microemboli can be effectively filtered by a filter to prevent pipeline blocking during circulation, so that reliability in circulation is realized.

Description

technical field [0001] The invention belongs to the field of auxiliary medical devices, in particular to a medicinal liquid perfusion circulation pipeline device for abdominal hyperthermia therapy. Background technique [0002] Abdominal hyperthermia uses the synergistic effect of regional high-dose hyperthermia and chemotherapy to kill cancer cells through hyperthermia and directly kill cancer cells through chemotherapy, and at the same time mechanically wash away free cancer cells in the abdominal cavity , its effectiveness has been confirmed by a large number of clinical trials, and it has been increasingly recognized as the first choice for the treatment of abdominal tumors. However, the current perfusion circulation circuit device based on hyperthermic intraperitoneal chemotherapy has defects and inconveniences in the following aspects: [0003] 1. The previous hyperthermic chemotherapy usually adopts the water bath method, the pipeline is simple, it is difficult to ach...

AI Technical Summary

Problems solved by technology

[0003] 1. The previous hyperthermic chemotherapy usually adopts the water bath method, the pipeline is simple, it is difficult to achieve precise temperature control, and the effect of hyperthermic chemotherapy cannot be achieved;

[0004] 2. The reliability of the circulation pipeline is poor, the process of filling the liquid medicine is complicated, and the operation is inconvenient; and the air is easily mixed in the liquid medicine during the circulation process, which is difficult to remove and affects the chemotherapy effect;

[0005] 3. The arrangement of temperature detection points in the circulation process is complicated, difficult to detect, and difficult to guarantee the temperature control accuracy;

[0006] 4. Using equipment such as heat exchange tanks and heat exchange tubes, it is inconvenient to recover and discard the liquid medicine
