Abstract
A syringe for controlled discharge and collection of fluids. The syringe includes a body having a hollow barrel, a first end with an opening for receiving a piston, and a second end having a nozzle. Flanges protrude from the first end of the body for manual engagement by a user. A piston having a longitudinal shaft is slidably received within the barrel. A first end of the piston has a gasket for slidably engaging the barrel to form a low pressure seal. A ring extends from the second end of the piston and defines a hollow receptacle for engagement by a user's thumb so that the piston may be urged into or withdrawn from the barrel. The ring has a broad flattened segment for supporting the syringe in an inverted position when the ring is placed on a horizontal surface. A tube adapter is provided on a frangible mounting on arms between the ring and piston shaft. A hole is provided in the piston for storing the tube adapter when it is not in use.
