Abstract
A single-hand controlled syringe having a plunger slidably mounted within a barrel. The plunger and barrel are of double wall construction with the outer wall of the plunger being slidably mounted in the space between the inner and outer walls of the barrel. A spring is mounted in the space between the inner and outer walls of the plunger. By this construction and arrangement, the alignment of the plunger within the barrel is maintained; the spring is hidden from view and the syringe can be easily assembled and disassembled for cleaning.
