ABSTRACT:
A syringe actuation device comprises an elastomeric element that is removably attachable to the outlet tip of a syringe, and to a grip member that allows the elastomeric element to be pulled distally along the syringe barrel to seat against the distal end of the syringe plunger. In first and second embodiments, the elastomeric element is attached between a grommet that fits around the outlet tip, and an end cap that engages the distal end of the plunger. When the grommet is seated around the outlet tip, and the end cap engages the distal end of the plunger with the plunger in its withdrawn position, the elastomeric element is stretched along the syringe, biasing the plunger toward its inserted position. As the elastomeric element restores itself to its unstretched configuration, it pushes the plunger into the syringe barrel. In the first embodiment, the elastomeric element comprises one or two elastic straps having first and second ends removably secured to the grommet, each strap having an intermediate portion secured to an end cap. If two straps are used, a first end cap engages the plunger, and a second end cap engages the first end cap. In the second embodiment, the elastomeric element is a continuous elastic band removably secured to the grommet and the end cap. In a third embodiment, the elastomeric element has a hole that receives the outlet tip, and the grip member is removably engageable with the elastomeric element for pulling the elastomeric element distally.
