  • Automatic syringe filling system
    Patent number: 4501306
    Abstract: An automatic syringe filling system includes a pump for supplying liquid under pressure to a manifold that distributes the liquid to each of a plurality of syringes. Microswitches disposed at predetermined positions detect when the plunger of each syringe connected to the manifold has been extended a particular distance determined by the desired fill volume. When all of the plungers are extended this distance, the supply of liquid to the manifold is discontinued by closing a valve and deactuating the pump.
