Description

Technical Field

[0001] The utility model relates to the technical field of three-way assembly of infusion sets, in particular to a semi-automatic assembly tool for three-way assembly of infusion sets. Background Art

[0002] The infusion tee is actually a three-way rotary valve. Its handle can rotate 360°. By turning the handle to different angles, the flow direction of different liquids can be controlled. Clinically, the tee can be used for drug injection, arterial blood sampling, central venous pressure monitoring, etc.

[0003] At present, the assembly of tees is done manually with conventional pressing machines. During the assembly process, the worker places the joint cap on the tee connector and then puts it into a conventional pressing machine for pressing. However, when assembling a slightly deformed tee, the conventional pressing machine will cause eccentricity due to unstable positioning, which will affect the stability of the product assembly and make the product defect rate high. In addition, conventional pressing machines can only process one product at a time, and the next processing can only be carried out after one product is processed, which has low production efficiency.
