Hypodermic dosage measuring device
First Claim
1. A hypodermic dosage measuring device to be utilized with a hypodermic syringe of the type including a needle, a dosage holding area, a flanged handle portion, and a plunger element slidably disposed therein, and a conventional drug vial having a body, a neck, and a head portion through which the needle is inserted into the body of the vial;
- said hypodermic dosage measuring device comprising;
a vial holding portion connected to a syringe holding portion by a dose adjustment portion;
said vial holding portion comprising a recess adapted to hold the head of the drug vial non-slidably therein,said syringe holding portion including at least one channel member for receiving a side of the flanged handle portion of the syringe non-slidably therein, and being sufficiently spaced from said vial holding portion such that the needle of the syringe is disposed within the vial upon the vial being positioned in said vial holding portion and the handle portion of the syringe being positioned in said channel member;
said dosage adjustment portion including an elongate, generally L-shaped plunger holder;
said plunger holder including an elongate, toothed track segment slidable in a longitudinal direction parallel to a length of the syringe,said plunger holder further including a plunger engagement segment extending perpendicular from a proximal end of said toothed track segment so as to engage the plunger such that longitudinal movement of said track segment results in corresponding longitudinal movement of the plunger of the syringe,said dosage adjustment portion further including a gear element, said gear element including a plurality of teeth thereon such that movement of said gear element results in corresponding movement of said track segment,handle means extending from and fixed to said gear element to facilitate movement of said gear element, anddosage indicating indicia on said measuring device to visually indicate an amount of drug drawn into the syringe based on the position of said handle means relative to said dosage indicating indicia, wherein a position of said handle means relative to said indicating indicia visually indicates a relative position of said plunger engagement segment with respect to said vial holding portion.

Abstract
A hypodermic dosage measuring device to be utilized with a hypodermic syringe and a conventional drug vial, the dosage measuring device including a vial holding portion adapted to hold a head of the drug vial non-slidably therein, a syringe holding portion adapted to hold the syringe in a non-slidable position with a needle of the syringe disposed within the drug vial, and a dose adjustment portion, the dose adjustment portion including an elongate plunger holder and gear element, the plunger holder and gear element each including a plurality of teeth thereon such that movement of the gear element results in an elongate track segment of the plunger holder sliding in a longitudinal direction parallel to a length of the syringe. The plunger holder further including a plunger engagement segment extending perpendicularly from a proximal end of the track segment, the plunger engagement section being adapted to engage a plunger of the syringe such that longitudinal movement of the plunger holder results in corresponding longitudinal movement of the plunger of the syringe relative to a dosage holding area of the syringe, the precise dosage measure being indicated by dosage indicating indicia on the dose adjustment portion.
