Abstract

An arrangement for storing, transporting and administering a liquid, such as a medical liquid, comprises a syringe barrel. The proximal end of the syringe barrel is closed with a proximal closure element. At the distal end, there is a distal closure element. The two closure elements are connected to one another in a clip-like fashion via a connection element. At least one predetermined breaking point is provided between the two closure elements and the connection element. Thus, a tamper-evident closure for a syringe is formed.

Claims

1. An arrangement for storing, transporting and administering a liquid, comprising

a syringe barrel for receiving the liquid, said syringe barrel having a proximal end and a distal end,

a proximal closure element for closing the proximal end of the syringe barrel,

a distal closure element for closing the distal end of the syringe barrel, and

a connection element which connects the proximal and distal closure elements to one another in a clip-like fashion,

wherein at least one predetermined breaking point is provided between the two closure elements and the connection element.

2. The arrangement of claim 1, wherein the proximal closure element comprises a plunger stopper arranged in the syringe barrel, and a backstop preventing proximal removal of the plunger stopper from the syringe barrel.

3. The arrangement of claim 2, wherein the backstop is secured as a separate structural part on the proximal end of the syringe barrel.

4. The arrangement of claim 1, wherein the distal closure element and the connection element are connected integrally to one another.

5. The arrangement of claim 1, wherein the distal closure element and the connection element are two separate structural parts, the connection element engaging at least partially around the distal closure element.

6. The arrangement of claim 5, wherein the connection element surrounds the syringe barrel in a sleeve-like or pot-like fashion.

7. The arrangement of claim 6, wherein the connection element has at least one window-like recess in the area of the syringe barrel.

8. The arrangement of claim 1, wherein the connection element has wing-like projections on its outside.

9. The arrangement of claim 1, wherein the proximal closure element and the connection element are designed as two pieces but are connected to one another in an irreversible manner.

10. The arrangement of claim 9, wherein the proximal closure element and the connection element are connected to one another with a form fit.

11. The arrangement of claim 10, wherein the connection element has a ring portion which surrounds the syringe barrel and engages irreversibly in a groove formed on the proximal closure element.

12. A tamper-evident closure for a syringe barrel having a proximal and a distal end, the tamper-evident closure comprising a proximal closure element designed to be arranged on the proximal end of the syringe barrel, comprising a distal closure element designed to be arranged on the distal end of the syringe barrel, and comprising a connection element designed to connect the proximal and distal closure elements to one another in a clip-like fashion, wherein at least one predetermined breaking point is provided between the two closure elements and the connection element.

13. The tamper-evident closure of claim 12, wherein the proximal closure element comprises a plunger stopper to be arranged in the syringe barrel, and a backstop for preventing proximal removal of the plunger stopper from the syringe barrel.

14. The tamper-evident closure of claim 13, wherein the backstop is designed to be secured as a separate structural part on the proximal end of the syringe barrel.

15. The tamper-evident closure of claim 12, wherein the distal closure element and the connection element are connected integrally to one another.

16. The tamper-evident closure of claim 12, wherein the distal closure element and the connection element are two separate structural parts, the connection element engaging at least partially around the distal closure element.

17. The tamper-evident closure of claim 12, wherein the connection element surrounds the syringe barrel in a sleeve-like or pot-like fashion.

18. The tamper-evident closure of claim 17, wherein the connection element has at least one window-like recess in the area of the syringe barrel.

19. The tamper-evident closure of claim 12, wherein the connection element has wing-like projections on its outside.

20. The tamper-evident closure of claim 12, wherein the proximal closure element and the connection element are designed as two pieces adapted for connection to one another in an irreversible manner.

21. The tamper-evident closure of claim 20, wherein the proximal closure element and the connection element are designed to be connected to one another with a form fit.

22. The tamper-evident closure of claim 21, wherein the connection element has a ring portion adapted to surround the syringe barrel and the proximal closure element has a groove, the ring portion being adapted to engage irreversibly in the groove.
