Description

Technical Field

[0001] The utility model relates to the technical field of infusion set assembly, in particular to a plastic needle linear detection rotation mechanism. Background Art

[0002] Plastic needles, also known as plastic vial insertion needles, are a crucial component of medical IV infusion sets. Their function is to puncture the vial and maintain a clear path between the liquid in the vial and the infusion tubing. These needles typically consist of a needle body and an airway tube attached to the body. The airway tube is then connected to an air filter via a short exhaust tube.

[0003] Currently, during the assembly process of the infusion set, the airway tube of the plastic needle needs to be assembled with the exhaust short tube. However, in the existing technology, some plastic needles are difficult to distinguish in terms of feeding direction, which makes it impossible to use automated equipment on a large scale to achieve the assembly of the plastic needle and the exhaust short tube.

Therefore, it is necessary to design a plastic needle linear detection and rotation mechanism to detect the direction of the airway tube in the plastic needle and to rotate the airway tube facing backward to facilitate subsequent assembly with the exhaust short tube.
