Material 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, pneumatic unit
It 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 receives air pressure
When effect is opened, blood can be stopped, control the flow direction of blood, it flows to sanguimotor direction, pneumatic unit is controlled with monitoring
Unit processed is 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
Body section 41 and the second shell section 42, 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 through hole 43 and the shape phase of through hole 43
Identical valve 3, complete shell wall is formed when valve 3 is closed with the second shell section 42.Valve 3 is it can be appreciated that be second
The window opened up on the shell wall of shell section 42, window can be opened can close.
Further, the first shell section 41 is small, the reducing housing that 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 matches with the diameter of the second shell section 42.
Further, pneumatic unit includes the servomotor 6 that cylinder 5 and drive cylinder 5 are acted, 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 with display 9 with operation keyboard 10 respectively on embedded computer 7.Monitoring and Controlling unit is by embedded
