As an Orthopedist I have found that if I have to hold both the vial and the syringe while I draw up medications it poses numerous problems. The first problem is that when I was aiming the needle towards the small vial in my hand, if my aim were to be off there was a likelihood that I would end up sticking my hand. Another problem was that having only one free hand to draw up the syringe (while the other hand was holding the vial) required me to contort my fingers in such a way that led to fatigue. Another problem that came up was that in certain situations administering injections had to be done under aseptic conditions which became more difficult when I had to handle the vial at the same time. The Hands-free medicine vial holder solves all these problems.
