ABSTRACT:
A magnifying cylinder for insulin syringe utilizes a tubular body having at least a portion thereof transparent and configured to reside along the liquid containing portion of a hypodermic syringe. The transparent portion of the body extends along the length thereof and has the property of magnifying the scale on the length of the liquid containing portion of the syringe. A band is clasped frictionally on the outside surface of the tubular portion and carries a magnifying lens thereon positioned over the transparent portion of the tubular body. The lens apparatus is provided with an indicia line indicating the level to which liquid is to filled within the syringe. In one embodiment a pair of semi-annular grooves are disposed in the body portion so as to fix the band at a preferred location. In another embodiment the band may be positioned selectively along the length of the body portion. The body portion is provided with a longitudinal slit insuring grasping thereof to the cylindrical surface of the syringe.
