Problems solved by technology

[0004] In order to overcome the problem that the centrifugal blood pump does not have a pulsating effect in the prior art, and the pulsating blood pump causes great damage to the blood, the present invention proposes a new type of blood circulation device, which has the advantages of less blood damage and pulsating blood pumping. Double advantage of large perfusion output

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0021] The present invention provides a new type of blood circulation device that can reduce blood damage and produce a pulsating effect. The circulation device mainly consists of the following parts: centrifugal blood pump 2, elastic blood storage balloon 4, variable diameter hose 6 , Rotary valve 5, motor 7, circulation pipeline 3 and other components, the specific connection diagram is as follows figure 1 Shown. Wherein: the centrifugal blood pump 2, the circulation pipeline 3, the elastic blood storage balloon 4 and the variable diameter hose 6 are connected in sequence, and the rotary valve 5 is in the shape of a leaf and is fixedly sleeved on the output shaft of the motor 7 Above, the rotary valve 5 is arranged above the variable-diameter hose 6. The centrifugal blood pump 2 of the device is provided with a blood inlet 1 and the end of the variable-diameter ho...

Abstract

The invention discloses a novel blood circulating device which integrates the dual advantages of centrifugal blood pumping and pulsating blood pumping, can perform pulsating blood pumping in in-vitro assistance circulation and is used for heart failure assistance, extracorporeal circulation assistance in cardiac surgery and the like. The device is composed of a centrifugal type blood pump, an elastic blood storage balloon, a diameter-variable hose, a rotating valve, a motor, a circulating pipeline and other parts. Continuous blood supply of blood circulation is achieved through the centrifugal blood pump, and the diameter-variable hose is controlled by the motor to achieve pulsating type output. The device integrates that advantage that injuries to blood caused by centrifugal blood pumping are small; meanwhile, the pulsating type blood pumping effect can be achieved, heart blood pumping can be really simulated, and the blood perfusion amount of tissue in the circulating process can be improved.

Description

Technical field: [0001] The present invention relates to a new type of blood circulation device, which is used for assisting heart failure and assisting extracorporeal circulation in cardiac surgery. Background technique: [0002] The blood circulation device is mainly used for heart failure assistance and extracorporeal assisted circulation. It is a key technology to replace the human heart beat and blood circulation. It is of great significance for the treatment and development of critical emergency and cardiovascular disease. [0003] At present, the blood circulation devices commonly used in the world can be roughly divided into centrifugal pumping and pulsatile pumping. Centrifugal pumping can continuously output blood, with little blood damage but no pulsating effect, and the effect of blood perfusion in the human body is slightly poor. , Can not completely replace the heart and provide a pulsating blood environment for human tissues. Pulsatile pumping mostly uses rolling or...
