ABSTRACT:
A syringe device is disclosed which employs an operator cooperable with the plunger of a syringe cartridge to facilitate discharge of fluid from the syringe cartridge. Various embodiments of the operator each include a sleeve portion which progressively telescopes the barrel of the syringe cartridge to prevent its fracture and lend stability to the assembly during operation. The operators are cooperable with the syringe cartridge to selectively discharge one or more predetermined dosages from the syringe.
