ABSTRACT:
A syringe apparatus is provided having a first control syringe with a hypodermic needle for injecting medication into a patient. A three-way stopcock interconnects the first syringe with the hypodermic needle and also interconnects the first syringe with a second reservoir syringe. A handle lever on the stopcock may be positioned to provide a first fluid flow path between the first syringe and the hypodermic needle to permit injection of medication into the patient. The handle lever of the stopcock may alternatively be positioned to provide a second fluid flow path to permit the first syringe to be refilled with medication from the second reservoir syringe for subsequent injection into the patient. The refilling of the first syringe from the reservoir syringe may be effected without removal of the needle from the patient and without disassembly of the first syringe.
