Abstract

The invention discloses a production process of a centrifugal blood pump rotor, which belongs to the technical field of medical device production process, and comprises the following steps: Step 1. Motor magnets and impellers are loaded; Step 2. Bearing magnetic stacks are pressed and installed in the impeller: 3. Four motor magnets are pressed into the impeller: the conveyor belt moves the pressed impeller to the bottom of the motor magnet installation mechanism, and the motor magnet installation mechanism presses the motor magnet into the impeller; Step 4. The base is pressed into the impeller and welded Forming, the invention can automatically complete the steps of pressing the bearing magnetic pile of the rotor of the centrifugal blood pump, installing the motor magnet and welding the base. The installation operation is carried out one by one; the process design of the present invention is ingenious, the connection between the processes is smooth, the produced product has good consistency, and the yield rate is high. In the whole process, more than 70% of labor can be saved, and it has good economic value.

Description

technical field [0001] The invention relates to the technical field of production technology of medical device accessories, in particular to a production technology of a centrifugal blood pump rotor. Background technique [0002] In cardiovascular medicine, the clinical use of artificial hearts (or blood pumps) as a bridge to heart transplantation or as a form of terminal therapy to support patients with advanced heart disease has become accepted clinical practice. The number of patients who suffer from heart disease and need heart replacement surgery is very large, but the serious shortage of transplant donors makes it difficult for most heart disease patients to treat and even lose the chance of survival. Therefore, it is of great significance to develop a high-performance heart pump. [0003] A ventricular assist device can use a blood pump to power the patient's blood, which pushes the blood to high pressure. One example of a ventricular assist device is a left ventric...
