example 1

[0164] Example 1, the blood pump may include at least two rotating devices; the rotating devices in the at least two rotating devices are connected in sequence; the first housing 200 includes an inlet port 220 and an outlet port 230; at least The lead-out port 230 of the former first shell 200 of the two rotating devices is connected to the lead-in port 220 of the latter first shell 200; the first accommodating cavity 210 of the former first shell 200 is connected to the latter. The first accommodating cavity 210 of a first housing 200 is in communication; since the guide assembly 400 is used to rotate the blood in the third direction, the guide assembly 400 can reduce the tendency of the first blade 120 to rotate the blood in the second direction, In order to provide power for blood to flow through multiple rotating devices, at this time, under the condition of providing the same flow rate and pressure for blood, the flow rate and pressure provided by a single rotating device ...

Abstract

The embodiment of the invention discloses a rotating device and a blood pump, and the rotating device comprises a first housing which is provided with a first accommodating cavity; the rotating assembly is arranged in the first containing cavity and can rotate in the first containing cavity; the rotating assembly comprises a first body and a first blade; a first through groove is formed in the first body; the first blade is fixed on the inner wall of the first through groove; the guide assembly is arranged in the first accommodating cavity; under the condition that the rotating assembly rotates, the first blade is used for pushing blood to flow in the first direction and rotate in the second direction; the guide assembly is used for rotating the blood in a third direction. According to the blood pump, due to the fact that the first blade is directly fixed to the inner wall of the through groove, shear stress is prevented from being generated between the first blade and the inner wall of the through groove, blood cell damage caused by gaps between the blades and the inner wall of the through groove can be prevented, and hemolytic reaction is prevented; the tendency that the first blade enables the blood to rotate in the second direction can be reduced through the guide assembly.

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 first vane in the prior art blood pump and the first through groove of the first body is likely to cause damage to blood cells, causing a hemolytic 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 pur...
