Abstract
A hand held device for loading a hypodermic syringe from a medicine vial is configured for easy placement of the syringe into a closely conforming channel in the proximal end of the device, with the needle end pointing towards the other end. The other end of the device is configured for easy placement of a standard vial into a closely conforming chamber with its penetrable cap facing the needle tip. Closing the device causes or permits the further action required for piercing the vial with the syringe needle. A sliding pull tab engages the syringe plunger so that gripping and pulling on the tab withdraws the plunger from the syringe, thus drawing fluid from the vial. An amplified or enhanced readout capability visually indicates the dosage of fluid withdrawn from the vial. An auxiliary needle mounted so as to be slightly offset from the syringe, provides for a supplemental piercing of the vial so that make-up air is available when large dosages are drawn from the vial with a single pull of the plunger.
