ABSTRACT:
A dispensing device comprises a metering assembly adapted to be coupled to a conventional syringe, which metering assembly includes a long length of capillary tubing through which the fluid must pass into a flexible hose which delivers the fluid and means for applying a uniform force to the plunger to provide fluid flow through the capillary tube at a slow, steady rate over a long period of time. The metering assembly includes parts moveable between a metering position at which fluid flowing through the metering assembly must pass through the capillary tubing, and a purging position at which fluid propelled by manual operation of the syringe can bypass the capillary tube and flow rapidly through the metering assembly to purge the hose.
