Abstract
The utility model relates to an external piston type blood pump for a heart-lung machine, which comprises a base plate, wherein a back plate is vertically arranged at one end of the base plate; a drive motor is arranged on the outer side of the back plate; flywheels controlled by the drive motor are arranged on the inner side of the back plate; pressing blocks are arranged at the lower parts of the flywheels; the pressing blocks extrude anti-backflow extrusion bags at the lower parts thereof; the anti-backflow extrusion bags are arranged on the base plate; a connecting rod is arranged between the flywheels and the pressing blocks; the back plate is provided with linear guide rails; the flywheels rotate to drive the pressing blocks to move up and down along the linear guide rails; the anti-backflow extrusion bags have blood flowing pipelines thereon; blood enters via a blood inlet pipe and flows out via a blood outlet pipe; and the blood pump for the heat-lung machine is further provided with a control circuit board. The device is simple in structure and convenient for operation and simulates the work of the heart and lung of human body; the extrusion mechanism extrudes the anti-backflow extrusion bags so that the blood flows towards a specific direction from the anti-backflow extrusion bags; and the extrusion mechanism does not need to extrude the anti-backflow extrusion bags completely as anti-backflow mechanisms are arranged in the anti-backflow extrusion bags, thereby preventing blood cells from being damaged by too much extrusion and increasing the quality of blood.
Description
Technical field
This utility model relates to a kind of external piston type blood pump device, relates to a kind of external piston type heart-lung machine blood pump especially.
Background technology
Present known heart-lung machine is made up of oxygenator and blood pump and auxiliary facilities, can carry out the machinery of extracorporeal circulation. and the heart-lung machine is used for the extracorporeal circulation of operation on heart, the assisted respiartion of lung transplantation, the auxiliary treatment of acute respiratory failure etc.Draw venous blood from Venous system, and at external oxygenate, again through the overall process of blood pump with the defeated vein system system that reverses of oxygenated blood; Satisfactory again lung turn of tidal stream; Be mainly used in heart, trunk operation, and the hemodynamics mechanism of heart-lung machine is a blood pump, existing blood pump also ought born the function that prevents backflow of blood under blood pressure when pressing blood; So it is very tight that blood pump must be pressed when extruding; So just cross the havoc hemocyte owing to reach pressure easily, blood quality is impacted, old for this reason mode is demanded urgently improving.
The utility model content
Providing of providing is a kind of simple in structure in order to solve the prior art deficiency, and be easy to operate, guarantees the external piston type heart-lung machine blood pump of blood quality.
The technical scheme that this utility model adopts:
A kind of external piston type heart-lung machine blood pump, it comprises base plate, base plate one end vertically is provided with backboard; The backboard outside is provided with drive motors, and the backboard inboard is provided with the flywheel of drive motors control, and the flywheel bottom is provided with briquetting; The anti-backflow squeeze bag of briquetting extruding bottom, the anti-backflow squeeze bag is placed on the base plate, is provided with connecting rod between flywheel and the briquetting; Backboard is provided with line slideway, and flywheel rotating band dynamic pressure piece moves up and down along line slideway, has the blood flow pipeline on the anti-backflow squeeze bag; Blood gets into from going out blood vessel output from going into blood vessel, and said heart-lung machine blood pump also is provided with control circuit board.
The outside that above-mentioned control circuit board is arranged on backboard is positioned at the drive motors bottom.
The technique effect that this utility model is obtained:
1, this apparatus structure is simple, and is easy to operate, the work of anthropomorphic dummy's systemic heart; Pressing mechanism extruding anti-backflow squeeze bag, blood flows towards specific direction from the anti-backflow squeeze bag, owing to there is anti-backflow mechanism to be arranged in the anti-backflow squeeze bag; Pressing mechanism can not kill the anti-backflow squeeze bag; Repeat action last time behind the return, avoid overvoltage to destroy hemocyte, improve blood quality.
