Abstract

The invention relates to a plug for placing on a connection element (1) of a medical syringe, which is connectable to the connection element (1), the plug (2) comprising a through-duct (3) and being formed free of further connectivity or connection elements.

Claims

1. A plug for placing on a connection element of a medical syringe, wherein said plug is connectable to the connection element, wherein said plug comprises:

a through-duct and is formed free of further connectivity or connection elements.

2. The plug according to claim 1, wherein said plug comprises an inner cone of a Luer cone, which is formed to cooperate with an outer cone of said Luer cone of said medical syringe

3. The plug according to claim 1, wherein said plug comprises an external thread of a Luer lock connection, which is formed to cooperate with an internal thread of a Luer lock connection of said medical syringe.

4. The plug according to claim 1, wherein said plug comprises latch or clip elements which cooperate with counter latch or counter clip elements of the connection element in such a way that the plug can be attached to the connection element in an irreversible manner.

5. The plug according to claim 1, wherein said plug comprises barb-like elements by means of which the plug can be attached to the connection element in an irreversible manner.

6. The plug according to claim 1, wherein said plug comprises a first portion and a second portion, and said second portion is connected to the first portion in a releasable manner by means of at least one predetermined breaking point.

7. The plug according to claim 6, wherein said at least one predetermined breaking point is in the form of a web.

8. The plug according to claim 6, wherein said first portion is formed in such a way that it is completely received in and/or depressed into the connection element when the plug is connected to the syringe.

9. The plug according to claim 1 further comprising at least one marking element, wherein said at least one marking element labels a said medical syringe provided with the plug for a particular type of application.

10. The plug according to claim 1, wherein said plug comprises at least in part a plastic material.

11. The plug according to claim 1, further comprising a sealing element formed as a valve, configured so that a medium can only pass through the through-duct in a direction out of the medical syringe.

12. The plug according to claim 11, wherein said valve is a non-return valve, a ball non-return valve, a poppet non-return valve, or a non-return flap.

13. The plug according to claim 7, wherein said first portion is formed in such a way that it is completely received in and/or depressed into said connection element when said plug is connected to said syringe.

14. The plug according to claim 1, wherein said plug comprises at least in part a thermoplastic elastomer, a rubber, a silicon or a combination thereof.
