Abstract
An improved tamper evident end cap assembly for a drug loaded syringe which assembly includes a syringe cap to close the discharge port in the nozzle of the syringe and an indicator ring about the nozzle connected by chads or tabs to a tubular shield which chads or tabs are adapted to break freeing the ring from the shield to loosely wobble on the nozzle indicating tampering if an axial force of separation is applied to the syringe cap to remove it from the syringe and a one way drive mechanism engaging both the shield and syringe cap so the shield may be rotated to advance the assembly onto a syringe nozzle but which is not responsive to counter rotation to withdraw the syringe cap to open the discharge port and gain access to the drug.
Claims19
A tamper evident end cap assembly for a syringe having a nozzle with a discharge port, said assembly comprising
- a) an end cap member disposed in at least partially covering relation to the nozzle,
- b) an indicator member detachably secured to said end cap member exteriorly of the nozzle,
- c) a syringe cap movably disposed within said end cap member into a fluid restricting position relative to the discharge port,
- d) a drive assembly interconnecting said end cap member and syringe cap, said drive assembly structured to dispose said syringe cap into said fluid restricting position upon selective movement of said end cap member, and
- e) said end cap member detachable from said indicator member and removable from both said syringe cap and the nozzle upon a predetermined force being applied to said end cap member.
