Description

Technical Field

[0001] The utility model relates to a cutting device applied to a blood bag with a special configuration, belonging to the field of blood bag cutting devices. Background Art

[0002] The blood component separation bag is one of the components of the blood component separator, and cooperates with the centrifuge cylinder of the blood component separator to complete the centrifugal separation of blood components. The separation bag needs to complete high-speed centrifugation with the centrifuge, and its structural design is different from that of ordinary blood bags. When the separation bag is used in conjunction with the separator, the pipeline is prone to bending and blocking, so it is necessary to cut 0.3cm cutting edges on both sides of the pipeline area of the separation bag when the separation bag is welded. The existing manual cutting method has many disadvantages: 1. The manual cutting accuracy is poor. When the cutting position is offset, the separation bag cannot be installed on the centrifuge cylinder. Excessive offset may even cause the separation bag to leak and cause the blood separation process to fail; 2. The cutting operation efficiency is low. Due to the high precision requirements for the cutting position and length, manual cutting requires pre-measurement and positioning before cutting, and the product cutting takes a long time.
