Background technology
Cardiac lumen operation must just can be carried out under direct-view condition, cut heart and also want the blood flow of temporary interruption superior and inferior vena cave, make in heart in depletion of blood state, under normal circumstances, venous blood flow dwell time must not surpass 3～4min, otherwise will cause death because of anoxia.If proof reduces the body temperature of animal in zoopery, one of the blood flow energy temporary interruption of heart is compared with the long time and the unlikely histanoxia that causes, after this with low temperature process, be applied to clinically simple chambers operation, and obtain many successes, but the major defect of the method is: easily produce cardiac arrhythmia, often therefore cause operative failure, and cause death; Blood Xining can not surpass 10min, within the so short time, is difficult to carry out complicated operation on heart.
Utility model content
This utility model is intended to address the above problem, a kind of artificial heart-lung system is provided, without oxygenator, has utilized autologous lung work, hematoclasis is few, loop is short, and preliminary filling blood volume greatly reduces, and gas exchange rate is high, can offer perfusion doctor accurately information be convenient to adjust in time, can offer surgical environments in comparatively clean chambers of the heart of operator, be convenient to operation and carry out, its technical scheme adopting is as follows:
An artificial heart-lung system, comprising: pulmonary vein intubate, emptying conduit, aorta conduit, myocardium protecting liquid intubate, venous blood storage tank, bubble removing device, aorta pump, suction pump, drain pump, myocardium protecting liquid charge pump, arterial filter, myocardium protecting liquid reservoir bag, temperature sensor, refrigerator, can heating tank, far-infrared heater and barostat, described pulmonary vein intubate is connected with the inlet of suction pump, described suction pump is connected with the inlet of venous blood storage tank, the liquid outlet of described venous blood storage tank is connected with bubble removing device, the liquid outlet of described bubble removing device is connected with aorta pump, the liquid outlet of described aorta pump is connected with the inlet of aorta conduit and myocardium protecting liquid charge pump respectively by three-way valve, described myocardium protecting liquid reservoir bag is also connected with the inlet of myocardium protecting liquid charge pump, and the liquid outlet of described myocardium protecting liquid charge pump is successively by temperature sensor, refrigerator, can heating tank and barostat be connected with myocardium protecting liquid intubate, described emptying conduit is connected with the inlet of drain pump, described drain pump is connected with the inlet of venous blood storage tank, described arterial filter is arranged at three-way valve to the pipeline of aorta conduit.
On technique scheme basis, also comprise bubble monitor, described bubble monitor is arranged at three-way valve to the pipeline of aorta conduit.
On technique scheme basis, described aorta pump, suction pump, drain pump and myocardium protecting liquid charge pump are centrifugal pump.
The utlity model has following advantage: without oxygenator; utilize autologous lung work; hematoclasis is few, and loop is short, and preliminary filling blood volume greatly reduces; gas exchange rate is high; can offer perfusion doctor accurately information be convenient to adjust in time, drain pump can be discharged the remained blood in the chambers of the heart, offers surgical environments in comparatively clean chambers of the heart of operator; myocardium protecting liquid can make cardiac muscle stop shrinking, and is convenient to operation and carries out.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model;
The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
An artificial heart-lung system, is characterized in that, comprising: pulmonary vein intubate 1, emptying conduit 2, aorta conduit 3, myocardium protecting liquid intubate 4, venous blood storage tank 5, bubble removing device 6, aorta pump 7, suction pump 8, drain pump 9, myocardium protecting liquid charge pump 10, arterial filter 12, myocardium protecting liquid reservoir bag 14, temperature sensor 15, refrigerator 16, can heating tank 17, far-infrared heater 18 and barostat 19, described pulmonary vein intubate 1 is connected with the inlet of suction pump 8, described suction pump 8 is connected with the inlet of venous blood storage tank 5, the liquid outlet of described venous blood storage tank 5 is connected with bubble removing device 6, the liquid outlet of described bubble removing device 6 is connected with aorta pump 7, the liquid outlet of described aorta pump 7 is connected with the inlet of aorta conduit 3 and myocardium protecting liquid charge pump 10 respectively by three-way valve 11, described myocardium protecting liquid reservoir bag 14 is also connected with the inlet of myocardium protecting liquid charge pump 10, and the liquid outlet of described myocardium protecting liquid charge pump 10 is successively by temperature sensor 15, refrigerator 16, can heating tank 17 and barostat 19 be connected with myocardium protecting liquid intubate 4, described emptying conduit 2 is connected with the inlet of drain pump 9, described drain pump 9 is connected with the inlet of venous blood storage tank 5, described arterial filter 12 is arranged at three-way valve 11 to the pipeline of aorta conduit 3, drain pump 9 can be discharged the remained blood in the chambers of the heart, offers surgical environments in comparatively clean chambers of the heart of operator.
It should be noted that due to the dirty difficulty that not only increases operation of pulsatile heart herein, and because its mechanical activity can consume a large amount of ATP enzymes, impel myocardial ischemia mortality, become one of major obstacle of operation on heart.Therefore after containing certain proportion and stoping jumping the myocardium protecting liquid of liquid and blood hybrid cooling, defeated time heart makes it stop jumping the effect that can reach cardioprotection, and myocardium protecting liquid charge pump can provide a feedback driving force.
