Improved safety syringe comprises a syringe cylinder and two-piece finger support which exhibits supporting and bolting device elements

摘要

The syringe cylinder (3) exhibits a projection which is seized by the finger support (5). The supporting element (13) exhibits an edge-open recess (19) for a piston rod importable into the syringe cylinder. The bolting device element exhibits an end piece which is complementary to the recess formed in the supporting element. A bolting device edge is arranged at the supporting element, which is combined with the bolting device element and comprises tooling hole for the admission of the rest arm.
