Abstract:
A pre-filled syringe, comprising:a syringe body, said syringe body having a partially open end;a needle:a hollow needle cover;said needle selectively retained within said needle cover;a storage attachment means selectively sealingly attaching said needle cover to said body through said body open end so that at least a portion of said needle cover is located within said syringe body;said storage attachment means thereby defining a storage position for said syringe when said storage attachment means is engaged;an operational attachment means selectively attaching said needle to said syringe body for operation of said syringe;said operational attachment means thereby defining an operative position for said syringe when said operational attachment means is engaged;the majority of said needle cover located within said syringe body when said syringe is in said storage position;wherein said needle includes a needle puncture end and a needle attachment end;said needle cover includes a closed needle cover first end and an open needle cover second end;said needle cover first end corresponds to and selectively houses said needle puncture end when said needle is retained within said needle cover;said needle cover second end corresponds to and selectively houses said needle attachment end when said needle is retained within said needle cover;said needle cover first end located within said syringe body when said syringe is in said storage position;said needle cover second end located exterior to said syringe body when said syringe is in said storage position;said syringe body further includes a syringe body opening on said syringe body partially open end;said syringe body further includes a syringe body neck extending from the perimeter of said syringe body opening in a direction away from said syringe body;said needle cover further includes a needle cover shoulder and a needle cover outer surface;said needle cover shoulder located proximate said needle cover second end;said needle cover outer surface having a cross-sectional area;said needle cover outer surface cross-sectional area being generally uniform from said needle cover second end to said needle cover shoulder;said needle cover outer surface cross-sectional area decreasing at said needle cover shoulder;said needle cover outer surface cross-sectional area gradually decreasing from needle cover shoulder to said needle cover first end;said syringe body neck includes a front surface located distal to said syringe body; andsaid needle cover shoulder abuts said body neck front surface when said syringe is in said storage position.
