  • Gauge device for hypodermic syringes
    Patent number: 4248225
    Abstract: A gauge device for a hypodermic syringe may be readily applied to the flanged end of the hypodermic syringe barrel. The gauge device includes a rigid bar which is spaced a predetermined distance from the free end of the plunger of the hypodermic syringe when the plunger is fully extended into the syringe barrel. The bar limits the retractive movement of the plunger from the barrel and therefore limits filling of the hypodermic syringe to a predetermined dosage.
