LUER CONNECTION ADAPTERS FOR RETRACTABLE NEEDLE SYRINGES

摘要

A connector mountable to a syringe barrel has a proximal barrel-engaging portion, a distal luer fitment portion, and a fluid aperture therethrough. The barrel-engaging portion of the connector includes an axial ledge configured to abut the axial distal edge of a glass syringe barrel. The connector facilitates mounting a luer assembly to the barrel. The luer assembly may be a tip cap having a complementary luer fitment for connection to the luer fitment portion of the connector. The luer assembly may be a luer needle assembly having a complementary luer fitment for connection to the luer fitment portion of the connector. The connector and syringe may further include an immobile, compressible needle seal. The needle seal is adjacent to or engageable with the barrel-engaging portion of the connector. The syringe may be configured with a plunger capable of engaging a retractable needle.

主权项

1. A syringe comprising:
a barrel; a plunger; a distal connector comprising a fluid aperture and a distal portion configured to engage a luer fitment; a needle seal, located at least partially proximal to the distal connector, having a fluid aperture therethrough; and a tip cap engaged with the distal connector, the tip cap comprising a proximal portion abutting the distal portion of the distal connector; wherein the tip cap is configured to provide evidence of tampering to a user upon removal of the tip cap from the distal connector.
