ABSTRACT:
The syringe dispensing apparatus of this invention is adapted to dispense fluid under pressure from or vacuum fill a conventional plastic disposable syringe having a cylindrical reservoir and a piston plunger having an elongated body portion, generally cruciform in cross-section with radially extending vanes. The dispensing apparatus includes a hand operated ratchet mechanism and a supporting alignment collar which is received around the syringe reservoir, at the open end. The collar has a transverse flange including a slot which receives one of the vanes of the plunger, which aligns the ratchet mechanism on the syringe. The ratchet mechanism includes a pair of handles releasably attached to the opposed ends of the collar and a sharp detent which digs into and grips one of the opposed aligned vanes of the plunger, to telescope the plunger into the syringe reservoir and dispense a metered volume of fluid through the restricted syringe outlet.
