摘要： A hypodermic syringe with a snap fitted handle grip retained on the syringe by a cam lug. A spring biased plunger of the syringe is attached to a metering rod extending longitudinally along side the plunger and through a guide passage in the handle grip. This metering rod has a circumferentially gripping spring stop that is manually slidable along the metering rod to set a particular dosage for the pumping syringe. A dispensing end of the syringe is connected to a double check valve system which is in turn connected to a reservoir container. This syringe pumping system is useful in hospital pharmacies for filling a series of smaller syringes or vials with metered dosages of diluent of medicament from a larger bulk reservoir container. It is also useful for hospital procedures, such as a thoracentesis, or other industrial or laboratory uses.
