Abstract

The invention relates to a vaneless blood pump. The vaneless blood pump comprises a volute, at least one separating piece, a rotor, a diversion piece and a power device; the volute is provided with a first cavity, a first liquid inlet and a first liquid outlet, wherein the first liquid inlet and the first liquid outlet are communicated with the first cavity; the separating piece and the rotor are arranged in the first cavity; the separating piece is provided with a second cavity, a second liquid inlet and a second liquid outlet, wherein the second liquid inlet and the second liquid outlet are communicated with the second cavity; the rotor is sleeved with the separating piece and fixedly connected with the separating piece through the diversion piece; a laminar flow channel is formed between the inner wall of the separating piece and the outer wall of the rotor. By supplying blood in this mode, the blood which needs to be supplied can flow in a laminar flow state, so that phenomena of hemolysis and thrombosis do not occur to the blood easily; meanwhile, the blood is not squeezed in the laminar flow mode, the damage to the blood is relatively small, long-term blood supplying can be conducted, the requirements of long-term blood supplying can be met, and the quality of the blood is ensured.

Description

technical field [0001] The invention relates to a blood delivery device, in particular to a bladeless blood pump. Background technique [0002] In a conventional blood pump, the blood is pushed by the blades, and the blades will give the blood a relatively large driving force, but it will also bring relatively large disturbances, and the blood generally remains in a turbulent flow state. Due to the high speed of the impeller, the red blood cells in the blood, the blades and the pump wall will be damaged by impact, which will easily lead to damage to the red blood cells, and the hemolysis caused by the damage to the red blood cells is still very serious. This pump can only be used for a short period of time. It is not conducive to use in occasions that require a long-term stable blood supply (for example, in the case of liver perfusion and other situations that require blood supply for more than 24 hours, it is difficult to meet the requirements of the blade-propelled blood ...
