Abstract: A padlock is provided with a multi-layer protective metal shell having non-aligned, alternating seams among the various layers, primary and secondary key-operable locks attached to the shackle of the padlock by a drive linkage that will fail before the primary and secondary locks to maintain the integrity of the lock, an ergonomic shape, an offset shackle for facilitating use of the lock in close-quarters applications, and a modular cushioned bumper for attachment to the outside of the lock body that is color-coded to correspond to a key and includes a protective cover over the keyway accessing the lock cylinder which is moveable to facilitate insertion of the key into the padlock.

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 An amplified or enhanced readout capability visually indicates the dosage of fluid withdrawn from the vial.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.
