ABSTRACT:
A dosage control device, particularly suited for use by persons with impaired vision who from time to time may give themselves injections such as diabetic. The dosage control device is a sheet like, elongated plastic member having a transverse slot for snapping over the finger projections on the end of a standard hypodermic syringe. A scale is provided in a predetermined disposition with respect to the slot so that when the device in conjunction with the outer end of the plunger duplicates the normal scale on the syringe. In use, a doctor or other person would cut off the outward extending end of the device at the scale marking for the desired dosage, so that the diabetic could control his dosage by feel rather than sight.
