Abstract
Abstract Disclosed is an apparatus which automatically charges a hypodermic syringe or the like, with a predetermined metered amount of medicinal solution such as insulin or the like. A pedestal or base member carries the syringe and the container for the medicinal solution in a precisely spaced relationship such that retraction of the plunger of the syringe against an adjustable stop bar draws the precise predetermined amount of solution into the syringe.
