Abstract

The invention discloses an automatic production technology of a magnetic-fluid suspension type centrifugal blood pump, and belongs to the technical field of blood pump production processes. The automatic production technology comprises the following steps that 1, feeding and positioning of a lower shell assembly are carried out; 2, an impeller assembly and the lower shell assembly are assembled; and 3, an upper shell assembly and the lower shell assembly are assembled, and automatic discharging is carried out. The technology is ingenious in design, the efficiency is improved by 8-10 times compared with that of manual magnetic-fluid suspension type centrifugal blood pump production, one person can be responsible for 2-3 production lines, over 80% of labor can be saved, the yield is high, and the economic value is good.

Description

technical field [0001] The invention relates to the technical field of blood pump automatic production technology, in particular to an automatic production technology of magnetic liquid suspension type centrifugal blood pump. Background technique [0002] Artificially assisted heart pumps have evolved from the first generation of pneumatic pulsating pumps to the second generation of mechanical bearing impeller pumps, and now to the third generation of suspended blood pumps. Centrifugal blood pumps are equipped with blades on the shaft of the blood pump. When the shaft rotates at high speed, these blades will guide the blood and throw it to the outer edge. The dynamic action of the blades on the blood will form the arterial pressure. The magnitude of the pressure depends on the rotational speed of the impeller. Generally, the higher the rotational speed, the higher the arterial pressure. When the pressure in the blood bag decreases, blood from the outside flows into the bag,...
