External heart-lung life-supporting system with two beating pump

Abstract

The invention relates to an artificial heart's double pulsate pump external cardiopulmonary life supporting system, composed of blood pump, pipeline, rotary body, drive cell, routine cardiopulmonary device and so on, including a supporting body with side wall installed with knob and roller, the first and second blood storages installed on the side wall, one end of the machine frame connected with the oxygenator through the vertical pipeline and the other end connected to large vein of the machine. Its advantages: remarkably reducing blood coagulation (thrombosis), blood resolution or destruction of red cell, its structure simple and stable, its bulk small and so on.

Description

technical field [0001] The invention relates to an artificial heart, in particular to a double-pulse pump extracorporeal cardiopulmonary life support system implemented in the form of artificial heart implantation or extracorporeal heart support for patients who need a cardiopulmonary life support system. Background technique [0002] Please refer to the attached figure 1 , 2 , 3, 4, and 5, where, figure 1 is a schematic diagram showing the heart 2, lung 4, blood circulation in mammals and humans, where the arrows indicate the direction of blood flow. Such as figure 1 As shown in , the heart 2 includes two atria above and two ventricles below, a main vein 6 is connected to the right atrium, the right ventricle is connected to the pulmonary artery 8, the lungs are connected to the left atrium, and the left ventricle is connected to an aorta 10, The regular pumping action of the left ventricle draws blood into the aorta 10, delivering nutrients and oxygen to every capillar...

AI Technical Summary

Problems solved by technology

However, except for the rubber membrane 49, 49', the blood still touches the mechanical surface, and the input and output ports are still exposed on the mechanical surface, which can cause thrombosis and hemolysis.

Moreover, the streamlined configuration of the inlet and outlet ports of the pump chambers 48, 48' can result in a pressure drop, resulting in blood coagulation and blood breakdown.

In addition, continuous friction and pressure can stretch the strip, making it difficult to maintain a steady pulse and blood pressure

Also, the conventional double-pulse blood pump 41 significantly increases the production cost due to the mechanical conditions required for the shuttle motion of the spherical body 52
