Unitary withdrawal spike unit suitable for factory fitting

摘要

A withdrawal spike unit (200) comprises a withdrawal spike component (30') and an integrally formed adapter component (60') that is adapted to couple with a vial (10) in a safe and secure manner. The integral formation of the component parts (30', 60') makes fully automated manufacture and assembly of assemblies comprising such a withdrawal spike unit (200) coupled to a vial (10) possible. As such, human errors associated with the assembly at the point of use are mitigated.
