Description
Technical field
This utility model relates to a kind of tumor medical treatment device, particularly a kind of hyperthermic perfusion chemotherapy device.
Background technology
Chemotherapy (chemotherapy, chemotherapy) is namely with the method for chemical synthetic drug treatment disease.Chemotherapy is one of Main Means for the treatment of at present tumor and some autoimmune disease, but in treatment, the patient generally has the side effect such as obvious nausea and vomiting, brings sense of discomfort to the patient.In body cavity, the perfusion chemotherapy medicine can reach higher drug level at intracavity, strengthens the direct cytotoxicity to cancerous cell.
Thermotherapy can play killing tumor cell by many-sided mechanism such as microcirculation, challenge in direct killing cytosis, apoptosis effect, change tumor.
Hyperthermic perfusion chemotherapy be above-mentioned chemotherapy and thermotherapy in conjunction with a kind of new therapy of application for the treatment of tumor, both bring into play collaborative Graft Versus Tumor.Its principle is to utilize the good chemotherapeutics of physical energy heat hot effect, be filled into tumor locus, make the tumor tissues temperature rise to effective treatment temperature, and keep certain hour, utilize normal structure and tumor cell to the difference of temperature tolerance, reach the therapeutic purposes that can make apoptosis of tumor cells, not damage again normal structure.Hyperthermic perfusion chemotherapy makes thermotherapy and infusion medicine produce organic complementary action, and heat effect can strengthen the cytotoxicity of chemotherapeutics, increases the patient to the sensitivity of chemotherapy.Can more effectively kill and wound malignant cell, improve patient's life quality, extend patient's life, alleviate again the side effect that radiation and chemotherapy produces simultaneously.
Studies show that at present, normal tissue cell can tolerate 47 ℃ of lasting 1h under hot conditions: and malignant cell only can tolerate 43 ℃ of lasting 1h, and 43 ℃ of lasting 1h are called as the critical temperature of malignant cell irreversible lesion.So, the primary requirement of body cavity perfusion thermochemotherapy device keeps stablizing effective filling temperature exactly, and existing perfusion Hyperthermic Chemotherapy Instrument heats by electric heater, although there is temperature to show, but have following defective: what 1. temperature showed only demonstration is that the electrical heating instrument is for the heating-up temperature of medicinal cupping, can not embody heating-up temperature in body cavity, have the temperature difference between both, cause actual intracavity heating-up temperature not enough; 2. thermoregulation mainly relies on manually, and automaticity is low, needs medical personnel to pay close attention at any time temperature information; 3. thermoregulation lags behind, and can not be down to as soon as possible design temperature as temperature higher than design temperature, easily causes the normal structure hot injury.
The utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of hyperthermic perfusion chemotherapy device is provided, and realizes that perfusion chemotherapy combines with thermotherapy, and automatic temperature-controlled adjusting has improved the perfusion chemotherapy curative effect, easy operating, safety, stable.
the technical scheme in the invention for solving the technical problem is: a kind of hyperthermic perfusion chemotherapy device, comprise electric heater unit and the medicinal cupping that is linked in sequence by conduit, enter the liquid constant flow pump, built-in pipe, the fluid constant flow pump, waste liquid tank, it is characterized in that: also comprise thermostat, described thermostat comprises the temperature sense probe that is connected with microcontroller circuit, power controller and electronics flow-limiting valve, described temperature sense probe is positioned at the built-in pipe root, described power controller is connected with the electric heater unit circuit, described electronics flow-limiting valve respectively with enter the liquid constant flow pump and be connected with fluid constant flow pump circuit.
Above-mentioned microprocessor also is connected with buzzer.
Above-mentioned microprocessor also is connected with display screen.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, utilize microprocessor to implement Automatic Control to the treatment temperature, automatically regulate electric heater unit by power controller, guarantee that the intracavity fluid temperature keeps constant;
2, temperature sense probe is positioned at the built-in pipe root, embodiment be the intracavity real time temperature, the Temperature-control Monitoring data are reliable;
3, utilize microprocessor to the control of electronics flow-limiting valve, reach and regulate the constant current flow rate pump, make flow velocity and Temperature Matching, as the excess temperature situation, can reduce timely into the flow quantity increase and go out flow quantity, replace out in body crossing the high temperature medicinal liquid, guarantee normal structure internal organs safety;
4, simple to operate, the display screen cavity temperature of withdrawing deposit in real time, as too high or too low, microprocessor by the buzzer automatic alarm, reduces medical personnel's control amount.
