AI Technical Summary

Technical Problem

Automatic syringe systems in existing drug delivery systems are difficult to ensure safe handling and disposal when removing the end cap and needle shield.

Method used

An end cap assembly is designed including a central axis and at least two clamping members. The clamping member extends in the direction of the central axis to form a circular segment and bends at the distal end toward the central axis to form a hook for wedging into the distal edge of the needle shield.

Benefits of technology

Safe and reliable needle shield removal is achieved, ensuring that the needle shield is removed along with the end cap assembly and can be retained in the end cap assembly for disposal or reattachment.

Abstract

The present disclosure relates to a drug delivery system comprising: a drug delivery device comprising a needle and a needle shield wherein a proximal end of the drug delivery device faces an injection site and a distal end of the drug delivery device faces away from the injection site; and an end cap assembly (1) wherein the end cap assembly comprises: a central axis and at least two clamping members (11). The at least two clamping members extend in the direction of the central axis and are arranged about the central axis to form a circular segment. The distal end of each of the at least two gripping members is curved toward the central axis to form a hook, wherein each hook (12) is configured to wedge into a distal edge of the needle shield. The invention also relates to a corresponding end cap assembly and a corresponding method.
