Syringe tip cap

摘要

A tip cap is provided comprising a base portion having an upper surface and a lower surface, a body having a top wall with a non-circular cross-section extending from the upper surface, and a shaft extending from the lower surface. A syringe assembly is provided comprising a syringe comprising a barrel, and a syringe tip, extending through the barrel and a connector provided on the syringe tip. The syringe assembly further comprises a tip cap for sealingly covering the syringe tip and comprising a base portion having an upper surface and a lower surface, a body having a top wall with a non-circular cross-section extending from the upper surface, and a shaft extending from the lower surface having connection means for attaching to the syringe tip.

1. A syringe assembly comprising:
a syringe having a barrel with an open proximal end and an opposed distal end with a cylindrical wall extending therebetween, and a luer tip formed at said distal end; and a unitary thermoplastic tip cap securable to said luer tip and comprising: a base portion having an upper surface and a lower surface, a body having a top wall extending from said upper surface and self-maintained in having a substantially non-circular cross-section in an unstressed condition when viewed at an angle substantially perpendicular to said upper surface, and a shaft extending from said lower surface, said shaft being shaped internally to releasably receive and contact the luer tip of the syringe and shaped externally to cooperate with a connector on the syringe, wherein said tip cap defines a continuous and uninterrupted sealing surface which continuously seals the luer tip of the syringe and contains the medicament within the syringe when said luer tip is releasably received in said shaft of said tip cap and until said tip cap is removed from said syringe, the medicament within the syringe being accessible through the luer tip of the syringe with removal of said tip cap, wherein said top wall has a non-circular elliptical shape.
