Syringe and locking device and method of assembling same |
摘要 |
A device for selectively locking a syringe plunger against longitudinal movement with respect to the syringe barrel includes two interlocking device parts. Each device part has a generally flat body with a generally semi-circular inner perimeter and first and second ends. A ridge extends along the inner perimeter of each half for engaging the syringe plunger when the plunger is rotated to a predetermined angular position. Each interlocking part has mating structures at each end for mating with the other device part and has a flange for retaining the assembled locking device on the syringe barrel. The syringe and locking device are assembled by inserting the plunger in the syringe barrel and then snapping the two device parts together around the proximal end of the syringe barrel.
