Abstract: A syringe is described incorporating a hollow body, a plunger therein, and a needle extending axially from the hollow body. The force required to depress the plunger is controlled by a friction device engaging the plunger, the friction device being adjustable by a threaded friction screw mounted in the hollow body. A finger grip is mounted on the friction screw and may be turned to adjust the position of the friction screw relative to the body.
