Problems solved by technology

Although the above design scheme reduces the volume of the pump body, the design of the blood pump inlet and outlet on both sides of the blood cavity is not conducive to the cooperation of the blood pump with the natural cardiovascular system after implantation in the body, resulting in greater blood flow resistance

Abstract

The invention discloses an implantable bionic flexible pulsatile pump driven by an ultrasonic motor. The pump comprises the ultrasonic motor, a groove cam, a roller follower, a slide block, an arc push plate, an elastic blood bag, a pump housing, a round separating plate and a linear guideway. According to The implantable bionic flexible pulsatile pump driven by the ultrasonic motor, the damage of blood pump to blood can be reduced effectively, the mounting location of the implantable bionic flexible pulsatile pump is not limited; the whole structure is compact, so that the volume of the pulsatile pump can be reduced effectively; and the implantability is added, so that the range of application suitable for the crowd is expanded.

Description

technical field [0001] The invention relates to a ventricular assist device in the technical field of medical instruments, in particular to an implantable bionic flexible pulsating blood pump driven by an ultrasonic motor. Background technique [0002] At present, heart disease has become one of the most important diseases affecting human health in the world. Mechanically assisted circulation is not only an effective method of cardiac assistance therapy, but also gradually developed into a permanent treatment for heart failure. Existing heart assist devices can be divided into centrifugal, axial flow and pulsatile blood pumps according to the blood supply mode. Both centrifugal and axial flow blood pumps need to use high-speed rotating blades. Because the shear stress generated by high-speed rotation has a strong destructive force on red blood cells and other blood cells, it is easy to form thrombus, cause stroke, multiple organ failure and other serious consequences. The...
