External circulation heat perfusion therapeutic instrument

Abstract

The invention relates to an external recycle thermal perfusion therapeutic equipment, comprising a water tank, a heater, a cooler, an external recycle pump, a recycle guide pipe, a heat exchanger, a temperature sensor and an industrial computer. An electric heating or semiconductor heating and semiconductor cooling constant temperature recycle device is adopted in the external recycle system of the invention; the temperature sensor is arranged in the perfusion end of an internal recycle system. The temperature of liquid at the perfusion end of the internal recycle system can be accurately controlled by that the heat exchanger supplies heat source for the internal recycle and the industrial computer sends heating or cooling signals to an electronic controller for controlling the heating or cooling; in constant temperature the temperature control precision is plus minus 0.1 DEG C, so that the purpose of thermal perfusion in constant temperature can be achieved.

Description

technical field [0001] The present invention relates to an extracorporeal circulation heat perfusion treatment instrument, which belongs to an intelligent extracorporeal circulation heat perfusion treatment system, which is used for preventing and treating recurrence and metastasis after resection of malignant tumors in the chest and abdominal cavity, and for treating malignant chest and abdominal cancer caused by advanced malignant tumors. Treatment of ascites. Background technique [0002] Surgical resection of malignant tumors in the thoracic and abdominal cavity is one of the important methods of treatment. However, some patients will relapse and die due to the implantation and metastasis of thoracic and abdominal lesions after operation. The reason is that there are free cancer cells and residual small lesions in the thoracic and abdominal cavity. , these exfoliated active cancer cells grow and multiply on the surface of the surgical wound and the surface of the thorax ...

AI Technical Summary

Problems solved by technology

There are many reports on this type of treatment equipment at present, such as Chinese patent (a kind of constant heat perfusion chemotherapy device CN02113630.0), infrared heat perfusion therapy instrument CN200410017707.X), closed cycle heat perfusion chemotherapy and ascites concentration reinfusion therapy With the instrument (CN00219340.X), the above-mentioned technologies have solved the problems of controlling liquid heating, perfusion drive, and reflux filtration to varying degrees, but there are still unreasonable design of the heating water tank, inaccurate temperature control of the heater, and hot perfusion liquid entering the body cavity. Disadvantages and deficiencies such as inaccurate temperature detection
