ABSTRACT:
A new and improved visual magnification apparatus for a syringe includes a base portion, a lens support portion attached to the base portion, and a magnifying lens attached to the lens support portion, wherein a syringe can be placed on the base portion and magnified by the magnifying lens. The base portion may include an internally concave cross-sectional contour that has a bottommost valley portion, such that a generally cylindrically-shaped syringe tends to rest in the valley portion under the influence of gravity. The base portion includes an ampule-supporting portion. The base portion also includes a slot portion capable of supporting a top portion of a syringe placed on the base portion. The base portion, the lens support portion, and the slot portion are in the form of a unified, integrated structure. The lens support portion may include an extension portion capable of retaining an ampule on the ampule-supporting portion of the base portion. An ampule alignment assembly may be connected to the base portion. An illumination assembly may be supported by the base portion. The location of the illumination assembly on the base portion is in opposition to the magnifying lens, such that the illumination assembly provides backlighting for the syringe when the syringe is positioned between the magnifying lens and the illumination assembly. An audible signalling assembly may be connected to either the base portion or to the lens support portion for providing an audible signal relating to syringe volume.
