  • a generally cylindrical hollow body shaped to receive a carpule, said body comprising a head portion on the upper end thereof;

    an axially movable clamping element rotatable about its longitudinal axis within the head portion of said body and engageable with an associated carpule to securely immobilize the carpule within the body of the syringe holder, said clamping element having a bore therethrough and comprising a handle portion and a barrel portion sized to rotate and translate within said head portion of said body;

    a plunger element having a rod portion which bears on its lower end a piston engaging means, said rod portion being axially and slidably receivable within the bore of said clamping element;

    a pair of pivotable jaws disposed on pivots on opposite sides of said body; and

    a sleeve element for opening and closing the jaws slidably disposed around the body of the holder and slidable between a downward position and an upward position, such that said sleeve element in the downward position closes the jaws around the carpule and in the upward position opens the jaws, thereby permitting the carpule to be received within, and then later ejected from, the holder in an axial direction.
