ABSTRACT:
A portable and hand held syringe filling device, having a frame that forms a curved channel, and one or more bulkheads fixed to the frame, that grip the barrel and flanges of a hypodermic syringe. A double acting air cylinder is fixed to one of the bulkheads, and is positioned within the frame channel, with the moving rod portion fixed to a slider having a thumb plate gripper that grips the thumb plate and plunger of a hypodermic syringe. The amount of air pressure and flow rate of the air pressure is specifically tailored to actuate the double action air cylinder, to provide an exact draw and dispense force on the syringe plunger. An adjustable stop is used to allow the syringe filling device to act as a pump, that delivers metered portions of liquid to target containers.
