Intraperitoneal hyperthermic perfusion chemotherapy instrument in operation

Abstract

The invention discloses an intraperitoneal hyperthermic perfusion chemotherapy instrument in operation, belonging to the technical field of medical instruments. The intraperitoneal hyperthermic perfusion chemotherapy instrument in operation comprises a heating device, a control device, a man-machine interaction device, a chemotherapy liquid collection bag, two adjustable speed peristaltic pumps, two T-junction dividers and a plurality of sensors, wherein the heating device comprises a heating plate and a heating bag, the heating plate and the heating bag are tightly stuck, the heating plate is connected with the control device to transfer heating temperature control information, and the inlet and the outlet of the heating bag are respectively provided with a temperature sensor. The invention has simple structure and convenient operation; the heating plate is utilized to carry out heat exchange so as to evenly heat, and the chemotherapy liquid is only sealed and circulated in the pipeline, which is clean and reliable; and the chemotherapy liquid collection bag can effectively collect and manage the chemotherapy liquid, and a DSP processor has precise temperature control and obvious curative effect.

Description

technical field [0001] The invention relates to a device in the technical field of medical instruments, in particular to an intraoperative abdominal hyperthermic chemotherapy instrument for treating abdominal malignant tumors. Background technique [0002] Intraoperative intraperitoneal hyperthermic chemotherapy utilizes the synergistic effect of regional high-dose chemotherapy and hyperthermia to induce apoptosis and necrosis of intraperitoneal tumor cells, and its clinical efficacy has been affirmed. However, the constant temperature heating of the chemotherapy solution has not been ideally solved. [0003] After searching the existing technical documents, it is found that the Chinese patent application number is: 200820104050.4, the publication number is: CN201157449Y, and the name is "body cavity continuous circulation thermotherapy instrument". After being heated in the middle, the puncture tube is connected, and the inlet and outlet pipes of the puncture tube are prov...

Problems solved by technology

But the technique uses microwaves to heat the structure, which can damage the chemotherapy fluid, interfering with the therapeutic effect

[0005] In addition, the medical instruments for this type of therapy in the prior art mostly use heat exchange tanks, heat exchange tubes and liquid storage containers. Although the problems of heating and chemotherapy liquid collection have been solved, they have the following disadvantages: 1. The temperature control accuracy of the chemotherapy liquid Not ideal, the temperature response is slow and the temperature change cannot be monitored in real time; 2. The chemotherapy solution is stored in the container, which is not conducive to its collection and disposal, and also brings inconvenience to the hygienic storage of the chemotherapy solution and instrument cleaning
