Fig. 2 is the structural representation of the utility model pump blood unit;
Fig. 3 is Fig. 2 upward view.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings:
A kind of pneumatic heart auxiliary pump blood device as shown in Figure 1, including pump blood unit, the upper surface of pump blood unit are set There is plastics valve 1, the lower surface of pump blood unit is connected by pipeline 2 with pneumatic unit, and pump blood unit is provided with valve 3, pneumatically Unit is turned on and off periodically penetrating blood to form pump blood unit by air inlet or outlet band movable valve 3, that is, valve 3 by When gas pressure is opened, blood can be stopped, control the flow direction of blood, it flows to sanguimotor direction, pneumatic unit and prison Control unit is surveyed to be connected.
Further, as shown in Fig. 2 pump blood unit includes the housing 4 of tubulose, housing 4 includes the first shell being sequentially connected The shell section 42 of body section 41 and second, plastics valve 1 are arranged on the top of the first shell section 41, the shell section 42 of pipeline 2 and second Bottom is connected, and uniform intervals are provided with through hole 43 on the shell wall of the second shell section 42, are provided with and the shape phase of through hole 43 at through hole 43 Identical valve 3, complete shell wall is formed with the second shell section 42 when valve 3 is closed.Valve 3 is it can be appreciated that be second The window opened up on the shell wall of shell section 42, window, which can be opened, to close.
Further, the first shell section 41 is reducing housing small, lower mouth is big suitable for reading, and the second shell section 42 is isometrical shell Body, the lower port diameter of the first shell section 41 match with the diameter of the second shell section 42.
Further, pneumatic unit includes the servomotor 6 that cylinder 5 and drive cylinder 5 act, the pressure chamber of cylinder 5 Connected with pipeline 2, the piston rod of cylinder 5 is connected by connecting rod 62 with the screw body 61 on servomotor 6.
Further, monitoring and controlling unit includes embedded computer 7, and embedded computer 7 passes through driver 8 and servo Motor 6 is connected, and is connected respectively with display 9 with operation keyboard 10 on embedded computer 7.Monitoring and controlling unit passes through embedded Computer 7 can continuous monitoring heart rate, the heartbeat amount of hitting, ventricular atrial and sound pulse pressure, so as to automatically adjust discharge rate and pressure, Inflow and outflow is set to balance each other, it is synchronous with the output of natural heart.
Further, as shown in figure 3, plastics valve 1 is fixed on the inwall on the top of the first shell section 41, and plastics valve 1 is convex configuration and convex surface is down-set, and cross recess is offered on plastics valve 1.The principle and cardiac valves of plastics valve 1 It is similar, cross recess is opened on an elastomeric material convex surface compatible with human body, because convex surface is inwardly set, in pump blood unit Insufficient pressure only could open cross mouth with the power inhaled with pushing open.
Further, valve 3 is fixed on the second shell section 42 by bindiny mechanism 31, and is provided with the bindiny mechanism 31 Torsion spring, torsion spring make valve 3 form the sealing state that closes with the second shell section 42, bindiny mechanism 31 and torsion when being acted on without external force Spring is arranged at the inside of the second shell section 42, avoids scratch tissue.
Further, housing 4, pipeline 2, valve 3, plastics valve 1 are made by the elastic-plastic material compatible with human body.
Concrete operating principle and the course of work of the present utility model are as follows:
In use, pump blood unit is by blood vessel and passes through cardiac valves, now the first shell section enters heart.Pass through operation Keyboard and display input stability bandwidth, the startup optimization on embedded computer to embedded computer, and embedded computer is pressed Moved according to the state modulator servomotor of setting, servomotor again by screw body and connecting rod drive piston in pressure chamber come Return and move back and forth.When the piston of pressure chamber moves right, the air pressure in the pump blood unit communicated by pipeline with pressure chamber becomes Small, due to the effect of torsion spring, valve is closed, and upper end plastics valve is opened, vascular access device;When piston is to left movement, pump blood Air pressure in unit becomes big, because plastics valve is difficult to open upwards, so forcing the valve on shell wall to be opened, in pump blood unit Blood flowed out from through hole, the valve of opening also has certain barrier effect, and promotion blood flows to sanguimotor direction It is dynamic, that is, play a part of accessory heart pump blood.So piston ceaselessly moves back and forth according to the parameter of setting so that plastics valve Constantly open, close with valve, endlessly power is provided for auxiliary pump blood circulation.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into In the range of.
