Abstract

The invention discloses a blood circulation assisting device and a control system, and the blood circulation assisting device comprises a sheath tube which is used for being installed in a blood vessel and is provided with a near end and a far end; the first balloon is arranged on the sheathing canal and is positioned in the blood vessel; the pump body is arranged at the far end of the sheathing canal and provided with a blood flow channel, a blood inlet and a blood outlet, the blood inlet and the blood outlet are communicated with the blood flow channel, and the pump body is used for pumping blood in the cardiac chamber into the blood vessel; the controller is arranged at the near end of the sheathing canal, and is configured to control the operation of the pump body and intermittently drive the first balloon to inflate and deflate, so that the first balloon at least partially blocks the blood vessel to cooperate with the pump body to generate pulsatile blood flow. According to the blood circulation auxiliary device and the control system, pulsatile blood flow matched with the heart pulsatile characteristics of the patient can be generated, and heart recovery of the patient is promoted.

Description

technical field

[0001] The embodiments of the present application belong to the technical field of cardiac assisted circulation, and in particular relate to a blood circulation assisting device and a control system. Background technique

[0002] Cardiovascular disease is a collective term for heart and vascular disorders, including coronary heart disease, cerebrovascular disease, rheumatic heart disease, and congenital heart disease. Coronary heart disease and stroke are usually acute diseases. The main cause is that blood vessels cannot flow to the heart muscle or the brain due to blockage of blood vessels, resulting in hypoxia and necrosis of organs and tissues. Clogged blood vessels can be caused by a variety of reasons, the most common of which is narrowing of blood vessels caused by the accumulation of fat in the lining of blood vessels.

[0003] The most commonly used treatment for various cardiovascular diseases is the left ventricular assist device. The blood pump c...
