Abstract
A device or arrangement for a carpule for a dental syringe permits the harpoon on the distal end of the plunger rod to engage the rubber or rubber-like plug or piston of the carpule, but blocks the piston from being pulled out the open proximal end of the tubular glass body of the carpule. A preferred version has an apertured cap that fits onto the proximal end of the carpule, a retaining neck ring that fits onto the penetrable seal at the proximal end of the carpule, and a bar connecting them. The bar also serves as a grip to assist in handling the carpule.
