Syringe for Direct Use with Medical Ampoules and Vials

Abstract

A kit for the direct use of a variety of medical ampoules of differing sizes, with a syringe, the kit having: a syringe body; a syringe plunger having a hollow interior volume; and a plurality of ampoule interface elements, each one being interchangeably received within the hollow interior volume and configured for deployment between an outer surface of the medical ampoule and a surface of the hollow interior volume so as to hold the medical ampoule therein, each of the plurality of ampoule interface elements having an outside diameter sized to fit an inside diameter of the hollow interior volume, wherein a first of the ampoule interface elements has an inside diameter for receiving a medical ampoule of a first size, and a second of the ampoule interface elements has an inside diameter different from the first inside diameter for receiving a medical ampoule of a second size.

What is claimed is: 
     
         1 . A kit for the direct use of a variety of medical vials of differing sizes, with a syringe, the kit comprising:
 (a) a syringe body;   (b) a syringe plunger configured for insertion into said syringe body, said syringe plunger having a hollow interior volume which is open at one end; and   (c) a plurality of vial interface elements, each one of said plurality of vial interface elements being interchangeably received within said hollow interior volume and configured for deployment between an outer surface of the medical vial and a surface of said hollow interior volume so as to hold the medical vial in said hollow interior volume, each of said plurality of vial interface elements having an outside diameter sized to fit closely against an inside diameter of said hollow interior volume of said syringe plunger, wherein a first of said vial interface elements has a first inside diameter for receiving a medical vial of a first size, and wherein a second of said vial interface elements has a second inside diameter different from said first inside diameter for receiving a medical vial of a second size.   
     
     
         2 . The kit of  claim 1 , wherein said vial interface is configured for deployment on the medical vial and said hollow interior volume is configured to accept insertion of the medical vial with said vial interface element deployed thereon.
