Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0023] The purpose of the present invention is to provide a novel magnetic coupling driven centrifugal blood pump which can be used for a long time without blood damage and blood pollution. Such as figure 1 As shown, the centrifugal blood pump includes a centrifugal pump upper cover 1, a rotor 3, an internal drive magnet 4 and a centrifugal pump lower cover 2; wherein: the centrifugal pump upper cover 1 and the centrifugal pump lower cover 2 cooperate to form an inner cavity A pump casing, a rotor 3 is arranged in the inner cavity of the pump casing, and the internal drive magnet 4 is installed on the rotor 4 through a slot opened on the rotor 3, and the internal drive magnet 4 is a neodymium-iron-boron magnet.

[0024] The upper cover 1 of the centrifugal pump is provided with a blood inlet 11 and a blood outlet 12. The ...

Abstract

The invention discloses a centrifugal blood pump driven by magnetic coupling, which is mainly used at occasions requiring in-vitro blood circulation such as in-vitro circulation assistance in a cardiac surgery and in-vitro membrane oxygenation. The centrifugal blood pump driven by the magnetic coupling is constituted of a centrifugal pump upper cover, a rotor, an internal drive magnet and a centrifugal pump lower cover. The centrifugal pump adopts a magnetic coupling drive manner to separate the centrifugal pump from driving, so that whole sealing of a blood circulation loop is realized, blood pollution is reduced, and disassembly and replacement become convenient. Streamlined design is adopted to rotor blades of the centrifugal blood pump and satisfies fluid dynamics requirements in the blood pump, so that blood can be flown out from a pump body stably and thrombosis is reduced. The centrifugal pump rotor is connected to the centrifugal pump lower cover through single-point spherical supporting, so that contact friction is reduced, and damages caused by friction-based heat generation to the blood are reduced.

Description

technical field [0001] The invention relates to the technical field of centrifugal blood pumps, in particular to a centrifugal blood pump driven by magnetic coupling. The blood pump can separate the drive from the rotor and make blood flow in a closed circuit. It is the core component of an extracorporeal blood circulation device. . It is mainly used in occasions requiring extracorporeal blood circulation such as extracorporeal circulation assistance and extracorporeal membrane oxygenation in cardiac surgery. Background technique [0002] The blood pump is mainly used in extracorporeal assisted circulation extracorporeal membrane oxygenation and other occasions that require extracorporeal blood circulation. It is a key technology to replace the human heart beating and blood circulation. It is of great significance for the treatment and development of severe emergency and cardiovascular diseases. . [0003] At present, the commonly used blood pumps in the world can be rough...
