Description

Technical Field

[0001] The utility model relates to the technical field of blood bag product assembly, in particular to a catheter and blood bag assembly device. Background Art

[0002] The existing disposable blood bag products are assembled by manual bonding of the catheter. The operator glues a proper amount of cyclohexanone glue on one end of the catheter in the length direction and then inserts it into the blood bag. The assembly is all done manually.
