Abstract

The utility model discloses an anticancer machine which heats and injects physic liquor into the abdominal cavity of a human body. The anticancer machine comprises a machine case, a liquor container, a liquor feeding pipeline, a heating device, an adjustable extruding pump and a temperature control system. The liquor container mounted in the machine case is connected with the adjustable extruding pump through the perfusion tube. The outlet liquor feeding pipeline of the pump is branched into two paths, and the crotch is provided with an extruding flow direction switch controlling the flow direction of the liquor. One path of branched pipeline is connected back with the liquor container and is provided with a device directly or indirectly heating the pipeline at the middle part; the other path of branched pipeline is directly led outside the machine case. While in use, the utility model directly injects the heated physic liquor in the abdominal cavity for chemotherapy in or after cancer operations.

Description

Heating perfusion instrument for cancers

This utility model relates to a kind ofly imports the intravital apparatus of people with medium, specifically is a kind of apparatus that medicinal liquid is filled into the abdominal cavity after heating.

Human abdominal cavity organ cancer in art or postoperative to adopt intraperitoneal hot perfusion chemotherapeutic method be a new technique, be considered to surgery alone, radiotherapy, chemotherapy, immunity and control the measure of a kind of Procarbazium of comprehensiveization preferably after the cancer, this theory is subjected to the numerous scholars' of medical circle attention, but does not see the apparatus report that with good grounds this theory and method are made as yet.

The purpose of this utility model is the theory according to intraperitoneal hot perfusion chemotherapeutic cancer treatment method, and a kind of apparatus that can pour into medicine of a warm nature liquid to human abdominal cavity internal control temperature control amount is provided, and easy to operate, safe in utilization.

The scheme that this utility model purpose realizes is that the described anticancer machine of perfusion of heating comprises casing, and liquid container is carried the liquid pipeline, heater, adjustable extrusion pump and temperature control system.The liquid container that is contained in the casing is connected by union joint and tube for transfusion, tube for transfusion is connected with adjustable extrusion pump again, delivery side of pump carries the liquid pipeline to be the two-way bifurcated, at crotch the flow direction that squash type flows to the gauge tap controlling liquid is housed, in the defeated liquid pushing tube of bifurcated one takes back liquid container makes the medicinal liquid can closed circuit, and in the defeated liquid pushing tube of this section, be equipped with and make the directly or indirectly device of heating of liquid in pipe, it specifically can be the microwave heating equipment or be connected with the PTC direct heating of power supply of packing into, also can be that the electric heater of packing in another container heats clear water in this container, by water indirect liquid in pipe, the attemperating unit of temperature-controlled is housed on the circuit of heater again through heating; The defeated liquid pushing tube of another bifurcated is directly to use when human abdominal cavity is poured into after drawing casing.During use, after in liquid container, pouring into medicinal liquid, start heater and adjustable extrusion pump, make liquid in defeated liquid pushing tube through heating after the loop arrive liquid container, when the liquid container inner liquid medicine reaches design temperature, the temperature control system auto power off stops heating, and keeps medicinal liquid to be in constant temperature, moves squash type this moment and flows to gauge tap the medicinal liquid that pumps is delivered in the human abdominal cavity through carrying the liquid pipeline.

The anticancer machine of perfusion of heating that adopts above scheme to make, simple in structure, easy to operate, be applicable to gastric cancer, cancer of biliary duct, cancer of pancreas, intestinal malignant tumor, colon cancer, bladder cancer, in uterus and adnexa malignant tumor and the soft tissue malignant tumour's resection operation or postoperative and above-mentioned tumor intraperitoneal plantation transfer member cancer ascites can not excision person treatment.The medicinal liquid of warp-wise intraperitoneal perfusion through heating, the destruction of warm acceleration cancer cell membrane, impel medicine to enter target cell, improve the concentration of cancer therapy drug in the tumor, strengthen the anticarcinogenic effect of medicine, prolong drug action time, make heat and cancer therapy drug produce synergism, both increased the generation of antitumous effect and don't increase toxicity of anticancer agents and side effect and complication, can kill operation effectively and cause the little cancer that comes off in Intraabdominal cancerous cell and intraperitoneal existence, kill and wound little solid tumor, prevent the tumor diffusion, thereby improve cancer patient's life cycle.This utility model also can cooperate vacuum pump to clean as paunch flusher, bladder and blood pump uses.

Below in conjunction with drawings and Examples this utility model is described in detail.

Fig. 1 is this utility model circuit block diagram.

Fig. 2 heats to pour into the longitudinal profile structural representation of an embodiment of anticancer machine.

Fig. 3 is that the longitudinal profile structural representation is looked on Fig. 2 embodiment left side.

Among Fig. 2-3,1. casing 2. liquid containers 3. heating containers 4. defeated liquid pushing tube 5. heating tubes 6. squash type pump heads 7. temperature sensors 8. electrothermal heaters 9. water level limiters 10. temperature sensors 11. instrument control stations 12. container cover 13. reversible electric machines 14. speed adjusting plates 15. water-supporting discs 16. universal wheels 17. squash types flow to switch 18. union joints 19. locate mode chutes 20. floats 21.
