Patent number: 5460617Abstract: The present invention is directed to a syringe plunger for use to administer a solution front a syringe of the type having an axially slidable piston sealing an axially extending barrel having a nozzle. The plunger includes a rigid stem member axially extending from a distal end to a proximal end. The plunger also includes threads or other attaching mechanism at the proximal end of the stem for removable attachment to the slidable piston. The stem member includes a first surface at the distal end of the stem for application of axial force to the stem so as to move the slidable piston in the barrel. Advantageously according to the invention, the stem also includes a second surface at an axially intermediate position on the stem for alternative application of axial force to the stem so as to initially move the slidable piston in the barrel, which is especially convenient for syringe users with small hands.Type: GrantFiled: July 28, 1994Date of Patent: October 24, 1995Assignee: Abbott LaboratoriesInventors: Marc S.
