ABSTRACT:
A syringe, particularly for epidural anesthesia, has an elastomeric driver in the form of a single elastic band perforated for mounting onto the tip of the syringe between the barrel and the needle hub. The elastic band is stretched into engagement with the thumbrest of the plunger to drive the plunger to full depression into the syringe barrel. The elastic band extends symmetrically on either side of the barrel to apply balanced force. Various configurations for the elastic band are disclosed.
