Adapter system for syringe pre-filled with liquid medicament and syringe pre-filled with liquid medicament
First Claim
1. An adaptor system comprised of a plastic syringe which is pre-filled with a liquid medicament, and a plastic flange adaptor which can be attached to said syringe;
- whereinsaid medicament-prefilled syringe comprises a nozzle, a cylindrical body and an end flange in this order;
said cylindrical body comprising a small outside diameter cylindrical body adjacent to said nozzle and a large outside diameter cylindrical body adjacent to said end flange;
said large outside diameter cylindrical body having a larger outside diameter than said small outside diameter cylindrical body and said small outside diameter body and said large outside diameter body together forming a common interior cylindrical chamber of uniform diameter; and
whereinsaid flange adaptor comprises;
a cylindrical base portion having an insertion hole whose diameter is such that the inner wall of the insertion hole does not make contact with said small outside diameter cylindrical body of said syringe and is in contact with said large outside diameter cylindrical body when said flange adaptor is inserted onto said syringe; and
a large diameter flange portion which surrounds said end flange of said syringe when said flange adaptor is inserted onto said syringe.

Abstract
An adaptor system includes a plastic syringe which is pre-filled with a liquid medicament, and a plastic flange adaptor which can be attached to the syringe. The medicament-prefilled syringe is provided with a cylindrical body having a small diameter cylindrical body to which a liquid medicament information label is adhered and a large diameter cylindrical body, and an end flange. The flange adaptor is provided with a cylindrical base portion having an insertion hole whose diameter is such that the inner wall of the insertion hole does not contact the small diameter cylindrical body of the syringe and is in contact with the large diameter cylindrical body when the flange adaptor is fitted to the syringe, and a large diameter flange portion which surrounds the end flange of the syringe. The invention is also directed to a medicament-prefilled plastic syringe itself.
