Operation principle of the present invention is as follows: the ratio of setting the advance and retreat time limit of the round pump chamber squeezer of straight line by programming, make squeezer strengthen gradually the dynamics of extruding pump chamber, generation puts on the pressure of pump chamber inner blood, blood is flowed to pump chamber delivery outlet, the quick rollback of squeezer subsequently, remove the extruding to pump chamber, allow pump chamber utilize the pressure of input port blood and the elastical retraction power of self to restore to the original state.There is external valve in the output input pipe outside that pump chamber connects, and valve is by the synchronous opening and closing of mechanical actuating unit.So go round and begin again, thereby simulated the duty of contraction and the diastole of ventricle.Pump chamber divides left pump chamber, right pump chamber, and two pump chambers synchronously carry out the action of supercharging and reset blood pressure lowering, thereby produces continual pulsatile flow.
Work process of the present invention is as follows: come and gone the operation of pump chamber squeezer by programmed control electric machine servo system control straight line, the amplitude that moves forward and backward of squeezer, the regulation and control of frequency capable of dynamic.The crushing block of the push rod front end of squeezer contacts with the force side, rear portion of pump chamber, and the direction of extrusion of squeezer and pump chamber delivery outlet direction of flow of blood are in full accord.Pump chamber outlet tube is connected with pressure inductor, and the signal feedback of induction apparatus is in system, and system can be by the thrust power intensity of the instantaneous adjustment squeezer of predetermined value.External control valve has left and right two groups, and each group is synchronously carried out the folding of a delivery outlet and two input ports.External control valve obtains the power of valve folding by being connected in the mechanical actuating unit of the squeezer seat of honour, while realizing extruding by valve trigger control device again, double pumping chamber delivery outlet is opened, input port closure, delivery outlet closure when extruding finishes, the operation that open input port.Because the crushing block of the push rod front end of squeezer has unique shape-designing, crushing block is hemisphere face moulding, has the contact area larger with pump ball, when this design makes briquetting extruding, the pressure of blood is reduced, and the infringement of the effective ingredient to blood reduces as far as possible.The design of driven by shaking assembly is mainly used in coordinating the pipeline of blood pump that the debugging before location, equipment live operation is installed.In addition, under the powering-off state that meets accident, driven by shaking assembly also can provide emergency power support, thereby improves the safety coefficient of blood pump.
This blood pump is driven by the motor of 100W left and right power, can produce the adjustable easypro contracting cycle of 60 beats/min of 0->, the blood flow 10ml-50ml that the single rotation period of each pump chamber produces; Maximum blood flow 6L/min, can produce the pulsatile flow of 10-200mmHg adjustable pressure.
