Abstract

The embodiment of the invention discloses a rotating device and a blood pump, and the rotating device comprises a rotating assembly which comprises a body and blades; a through groove is formed in the middle of the body; the blade is fixed on the inner wall of the through groove; under the condition that the rotating assembly rotates, the blades are used for pushing blood to flow in the through grooves. According to the blood pump, due to the fact that the blades are directly fixed to the inner walls of the through grooves, no gap exists between the blades and the inner walls of the through grooves, shear stress is prevented from being generated between the blades and the inner walls of the through grooves, and the situation that the gaps between the blades and the inner walls of the through grooves cause damage to blood cells and hemolytic reaction can be prevented; meanwhile, the blades are suspended in the middle of the through groove and are not connected with the hub, so that a low-speed area at the joint of the blades and the hub is eliminated, the possibility of blood deposition is reduced, and blood coagulation is prevented.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a rotating device and a blood pump. Background technique [0002] The blood pump is a commonly used medical device, and the blood pump can provide the power to flow the blood. For example, the heart is the power organ of the human body. The main function of the heart is to provide power for blood flow and transport blood to all parts of the body. When the patient's heart fails and cannot provide power, the patient's life is in danger. The patient's blood provides power. However, the gap between the vanes in the prior art blood pump and the through groove of the main body is likely to cause damage to blood cells, causing hemolysis reaction. SUMMARY OF THE INVENTION [0003] In view of this, embodiments of the present application are expected to provide a rotating device and a blood pump. [0004] In order to achieve the above-mentioned purpose, the tech...
