Abstract
An irrigation syringe is provided which includes a barrel having an axially extending annular groove open at the proximal end for receiving the connector portion of a resilient compressible syringe bulb in tight frictional fitting relation. The syringe barrel is adapted to receive, instead of the bulb, a plunger having a piston that may be inserted into the barrel to provide a piston-type syringe so that the barrel can be used either with a syringe bulb or a syringe plunger. The inner wall of the groove has a plurality of slots so that if the syringe barrel is employed as a funnel, liquid will flow from the groove into the barrel.
