Abstract
An injection assisting apparatus for use with a disposable syringe includes a primary support attachable to the syringe barrel, a plunger head retainer connected to the primary support by a sliding shaft, and a plurality of finger rings attached to the support and retainer for moving one relative to the other to produce a corresponding movement of the plunger relative to the barrel of the syringe. In one preferred form, the primary support forms a clasp capable of snap-fitting about a portion of the barrel. In another preferred form, the primary support includes an alignment body pivotally connected to a barrel support frame. A thumb ring attached to the retainer is rotated with respect to the plane of the finger rings attached to the primary support, to conform closely to the natural orientation of the thumb with respect to the index and the middle fingers.
