Abstract
The utility model provides a thermal pouring therapeutic equipment of tumor which comprises a store bag, a constant temperature cabinet, a charge pump, a return liquor pump and a filter. Chemotherapy physic liquor is loaded in the store bag. The physic liquor enters into an abdominal cavity by the charge pump. Then the physic liquor passes through the filter and goes back to the store bag by the return liquor pump at the other end of the abdominal cavity. The warm chemotherapy physic liquor can circulate in the abdominal cavity so that the purpose of killing cancer cells which are leaked in an operation can be achieved. The successful rate of operation and the survival rate of patients can be effectively improved. The utility model can be acted as the device of the tumour operating room. The thermal pouring therapeutic equipment of tumor has the advantages of accurate temperature control, small volume, light weight, low cost and easy use.
Description
Technical field
This utility model relates to a kind of tumor thermal perfusion therapeutic instrument, belongs to medical instruments field.
Background technology
At present the late result of digestive tract tumor postoperative is still not ideal enough, is example with gastric cancer, and gastric cancer peritoneum shifts and accounts for about 50% of recurrent cases behind the radical operation for carcinoma of stomach.Causing peritoneal cancer to shift multiple reason is plantation, and a kind of is spontaneous plantation; Another kind is to separate or during the excision cancerous tissue in the operation, and cancerous cell comes off and the plantation that causes.To cause quite high complication in case form peritoneal seeding, and therefore, eliminate abdominal cavity free cancer cell and remaining small cancer, be the field, forward position in the present oncotherapy research.
Summary of the invention
The utility model proposes a kind of tumor thermal perfusion therapeutic instrument, purpose is: separate in operation or during the excision cancerous tissue, utilize warm and dual function chemotherapy, kill the cancerous cell of spill and leakage, the plantation that causes to eliminate abdominal cavity free cancer cell and remaining small cancer improves the success rate of operation and patient's survival rate effectively.
The technical scheme that this utility model adopted is: a kind of tumor thermal perfusion therapeutic instrument, and by storage bag, calorstat, charge pump, return liquid pump and filter is formed.The storage bag adopts medical macromolecular materials to make, and the chemotherapy medicinal liquid by the normal saline preparation is housed in the storage bag.Medicinal liquid enters the abdominal cavity through charge pump after heating by calorstat, and the other end by the abdominal cavity returns medicinal liquid to storage bag through filter by returning liquid pump again, and warm chemotherapy medicinal liquid is circulated in the abdominal cavity.
Calorstat is made of heater, temperature controller and pick off.Heater is to be composited successively by liner plate, far infrared radiation layer, heating layer, thermal insulation layer and casing; Heating layer adopts face resistance heated mode, is made by non-metal electrothermal material.
Pick off adopts the medical high-precision temperature sensor.Probe is coated by rustless steel, is placed in the abdominal cavity, and its temperature signal feeds back to temperature controller; Temperature controller adopts intelligent programmer regulation and control, control heater in good time.
Charge pump and return liquid pump and adopt closed contactless type of drive is to guarantee the aseptic circulation of medicinal liquid.
Filter adopts medical polymer film to make.
The utility model has the advantages that: temperature control is accurate, can make the constantly circulation in the abdominal cavity of homothermic medicinal liquid, gives full play to warm and dual function chemotherapy, to reach the purpose of killing the cancerous cell of spill and leakage in the operation.Simultaneously also to have a volume little, in light weight for this utility model, and cost is low, and is easy to use, the advantage of being convenient to promote.
Description of drawings
Accompanying drawing 1 is a tumor thermal perfusion therapeutic instrument structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model and technology contents thereof are described further:
Referring to accompanying drawing 1, tumor thermal perfusion therapeutic instrument of the present utility model is by storage bag 1, calorstat 2, charge pump 3, return liquid pump 5 and filter 6 is formed.It is characterized in that: storage bag 1 adopts medical macromolecular materials to make, and the chemotherapy medicinal liquid by the normal saline preparation is equipped with in its inside, and medicinal liquid enters abdominal cavity 4 through charge pump 3 after passing through calorstat 2 heating; The other end by abdominal cavity 4 returns medicinal liquid to storage bag 1 through filter 6 by returning liquid pump 5 again.
Referring to accompanying drawing 1 and accompanying drawing 2, calorstat 2 is made of heater 2-1, temperature controller 2-2 and pick off 2-3.Heater 2-1 is composited successively by liner plate 2-1-1, far infrared radiation layer 2-1-2, heating layer 2-1-3, thermal insulation layer 2-1-4 and casing 2-1-5; Heating layer 2-1-3 adopts face resistance heated mode, is made by non-metal electrothermal material; Pick off 2-3 adopts the medical high-precision temperature sensor, and probe is coated by rustless steel, is placed in the abdominal cavity 4, and its temperature signal feeds back to temperature controller 2-2; Temperature controller 2-2 adopts intelligent programmer regulation and control, control heater 2-1 in good time.
Filter 6 adopts medical polymer film to make.
Using method of the present utility model is: the storage bag that at first will install the chemotherapy medicinal liquid is put calorstat into, connect pick off, and place postoperative patient abdominal cavity on the operating-table, energized, the medicinal liquid in the heating storage bag, when medicinal liquid reaches design temperature, medicinal liquid after starting charge pump and will heating injects the abdominal cavity, reach required capacity after, restart and return liquid pump, adjust the flow of two pumps, make it constant.At this moment, after returning liquid pump the medicinal liquid in the abdominal cavity being filtered by filter, return the storage bag.Intraabdominal medicinal liquid can be kept required treatment temperature exactly under the control of calorstat.Homothermic medicinal liquid behind the circulation certain hour, can reach the therapeutic purposes of progressively killing the cancerous cell of spill and leakage in the operation in the abdominal cavity.
