Abstract

The invention provides an ultrasonic motor-driven diaphragm blood pump, which includes a shell, a rushing board, a transmission mechanism, an ultrasonic motor, annular blood bags, a blood inlet, a blood outlet, one-way valves, a driving module, and a monitoring and controlling module. The connection relationship is that: the shell and the rushing board are connected by the ultrasonic motor and the transmission mechanism, one side of the rushing board is connected with the annular blood bags, the other side of the annular blood bags is connected with the shell, the two annular blood bags are respectively provides with a blood inlet and a blood outlet; a built-in one-way valve is arranged in each blood opening to control the flowing direction of the blood, the monitoring and controlling module is connected with the driving module, the driving module is connected with the ultrasonic motor. The ultrasonic motor-driven diaphragm blood pump adopts the ultrasonic motor which is compact and flexible in structure and appearance, drive method, and transmission methods to implement the above built-in blood-pumping function directly, is ensured to be applicable to the short sufferers, and more applicable to the characteristics of Asian people.

Description

technical field [0001] The invention relates to a blood pump in the technical field of medical devices, in particular to an ultrasonic motor-driven diaphragm blood pump for ventricular assistance. Background technique [0002] For patients with end-stage heart failure, there are currently clinically available intra-arterial balloon pumps (IABP) and ventricular arterial bypass (V-AB) to assist the circulatory system. Among them, the ventricular assist device (VAD), as a kind of ventricular arterial side flow, can help patients with end-stage heart failure to pass the critical period of waiting for a heart donor; or for patients with chronic heart disease, it can also rely on various implantable VAD is supported by persistence. So far, diaphragm ventricular assist devices that have entered the medical market or have mature technology can be roughly divided into pneumatic and electric diaphragm ventricular assist devices. Diaphragm-type ventricular assist devices provide puls...
