Definitions
- the present invention relates to a syringe plunger used to support and move a gasket inserted into a syringe barrel.
- a syringe is used to draw a chemical solution into a syringe barrel when used.
- an already-filled syringe in which a syringe solution has been filled in advance has been developed to reduce the workload on medical sites. It is planned.
- prefilled syringes with contrast agents filled in syringe barrels have also been used.
- prefilled plastic syringes in which a contrast agent has been injected into a relatively large plastic syringe have also been used.
- the center axis of the syringe barrel When attaching the gasket to the tip of the plunger in this way, the center axis of the syringe barrel must be aligned with the center axis of the plunger. The screw at the tip of the plunger cannot be smoothly screwed into the rear surface of the gasket. However, it is not easy to make the center axis of the syringe barrel coincide with the center axis of the plunger. When the center axes of both are shifted, forcibly screw the threaded part of the plunger tip into the rear surface of the gasket. was there.
