The Prodigy Count-A-Dose allows a blind or visually impaired person with diabetes to fill an insulin 1/2cc syringe without assistance. Using Count-A-Dose is much less expensive than insulin pens and pre-filled reservoirs. The Count-A-Dose lets you safely fill insulin syringes with one or two bottles of insulin. The bottle holder is marked to identify bottles for easy mixing—one raised dot for the first bottle, two raised dots for the second.
With the click dial starting all the way down toward the raised minus (-) sign, the user simply moves the click dial the number of times, or clicks, per unit of insulin needed. Each click of the dial toward the plus sign (+) will draw one unit of insulin into the syringe.
