Abstract

The invention discloses a production process of a centrifugal blood pump rotor, and belongs to the technical field of medical instrument production processes. The method comprises the following stepsthat 1, motor magnets and impellers are fed; 2, bearing magnetic stacks are pressed into the impellers; 3, the four motor magnets are pressed into the impellers, specifically, a conveying belt moves the pressed impellers to the position under a motor magnet mounting mechanism, and the motor magnet mounting mechanism presses the motor magnets into the impellers; and 4, a base is pressed onto the impellers and welded and formed. According to the method, the steps of bearing magnetic pile press fitting, motor magnet mounting and base welding of the centrifugal blood pump rotor can be automatically completed, the four motor magnets can be installed in the impellers at the same time through the motor magnet mounting mechanism, and workers do not need to install the motor magnets one by one; theprocess is ingenious in design and smooth in procedure connection, the produced products are good in consistency and high in yield, more than 70% of labor can be saved in the whole process, and a high economic value is achieved.

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...
