ABSTRACT:
An elastomerically-actuated syringe actuation device comprises a grommet that fits around the outlet tip of a syringe; an end cap, having a finger grip, that engages the distal end of the plunger of the syringe; and an elastomeric element that connects the grommet and the end cap. When the grommet is seated around the outlet tip, and the end cap is engaged against the distal end of the plunger with the plunger in its withdrawn position, the elastomeric element is stretched along the syringe, between the grommet and the end cap, thereby biasing the plunger toward its inserted position. As the elastomeric element restores itself to its unstretched configuration, it provides a driving force against the plunger to push the plunger into the barrel of the syringe, thereby expressing the fluid contained in the barrel out of the outlet tip. In one embodiment, the elastomeric element is an elastic strap having first and second ends removably secured to the grommet so as to be length-adjustable, and an intermediate portion secured to the end cap. In a second embodiment, the elastomeric element is a continuous elastic band removably secured to both the grommet and the end cap. In both embodiments, the elastomeric element is secured to the end cap so that it is spaced away from the barrel of the syringe.
