Abstract

The invention relates to the technical field of medical instruments, and provides an interventional ventricular assist device which comprises an interventional tube, a motor assembly, a liquid injection barrel and an impeller assembly. The interventional tube is provided with a liquid inlet and a liquid outlet, the impeller assembly comprises an impeller, the impeller is contained in the intervention pipe, the impeller can rotate so that liquid can enter the intervention pipe from the liquid inlet and flow out from the liquid outlet, the motor assembly can generate a rotating magnetic field todrive the impeller to rotate, the liquid injection barrel can allow perfusate to be injected into the interventional tube, and the perfusate injected through the liquid injection barrel can provide thrust for the impeller assembly, so that the impeller can suspend and rotate in the interventional tube under the combined action of the motor assembly and the perfusate. According to the interventional ventricular assist device, suspension arrangement of the impeller can be achieved, mechanical collision of the impeller is avoided, the risk of blood compatibility is reduced, and thrombus is prevented from being formed at the bearing.

Description

technical field [0001] The present application belongs to the technical field of medical devices, and more specifically relates to an interventional ventricular assist device. Background technique [0002] Traditional interventional ventricular assist devices use mechanical bearings to achieve impeller rotation, which has mechanical friction, which will bring potential blood compatibility risks, and the bearing connection of mechanical bearings is prone to thrombus formation. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide an interventional ventricular assist device, so as to solve the technical problem of mechanical friction of the interventional ventricular assist device in the traditional technology that causes blood compatibility risks. [0004] In order to achieve the above purpose, the technical solution adopted by this application is to provide an interventional ventricular assist device, including an interve...
