Body cavity heat perfusion therapeutic instrument

Abstract

The present invention relates to a body cavity thermal perfusion treatment device, including a water tank, a heating pipe, circulating pumps, circulating guide pipes, a heat exchanger and a water tank controller, wherein, the water tank, an external circulating pump, an external circulating guide pipe and the heat exchanger constitute an external circulating system, the heat exchanger, an internal circulating guide pipe, an internal circulating pump and the body cavity of the human constitute an internal circulating system, and the present invention is characterized in that a constant temperature water tank which is provided with a heater is arranged in the external circulating system. The external circulating pump in the constant temperature water tank is arranged at the lower part of the water tank, the water tank is arranged at the upper part of a shell body, the electric heating pipe is arranged in the water tank, and a water level gauge which is communicated with the water tank is arranged at the side surface of the shell body. The present invention adopts an industry control computer to regulate the electric heating pipe which is arranged in the constant temperature water tank by the water tank controller, so as to accurately control the temperature of the liquid in the water tank, and the precision of the control temperature can achieve plus or minus 0.1 DEG C during the constant temperature, thereby achieving the purpose of constant temperature thermal perfusion treatment.

Description

technical field [0001] The invention relates to a circulation heat perfusion treatment instrument, in particular to a body cavity heat perfusion treatment instrument, which belongs to the technical field of medical instruments. Background technique [0002] The existence of free cancer cells and residual small lesions in the thoracic and abdominal cavity is the main cause of postoperative local recurrence or metastasis; malignant pleural and peritoneal effusions are the main complications of advanced body cavity malignancies; in the above cases, traditional treatment methods The effect is not good. Research has found that medical personnel use heat perfusion according to the different heat resistance of tumor cell tissue and normal tissue, combined with heat chemotherapy, can effectively kill residual lesions and free cells in the chest and abdominal cavity, improve the effect of surgical treatment and effective treatment Malignant pleural and peritoneal effusions. Up to n...

AI Technical Summary

Problems solved by technology

Up to now, this type of treatment technology means produced by applying the above theory has been widely used in hospitals, such as Chinese patent literature reports (see "A kind of constant heat perfusion chemotherapy device CN02113630.0" and "Infrared heat perfusion therapy instrument CN200410017707. X"), the above-mentioned medical device partially solves the problems of controlling liquid heating, perfusion drive, and backflow filtration, but there are still obvious defects, such as unreasonable design of the water tank, inaccurate temperature control of the liquid flowing into the cavity, etc.
