Claims for Patent: 7,857,802

Title:Connector for medical liquid-containing packages and medical liquid-containing packages
Abstract: The invention relates to a connector for medical liquid-containing packages, in particular to infusion or transfusion bags comprising a connection element (1) provided with a channel-shaped opening (1c) in which a self-sealing membrane (8) is arranged. A breakable part (17) which is connected to the connection piece closes the channel-shaped opening. Above the membrane (8), said connection element is embodied in the form a connection piece (13) comprising an internal cone (14) and external thread (15), the membrane (8) being sealed for receiving a syringe cone shaft. The inventive connector makes it possible to inject an active substance by means of a conventional Luer lock syringe devoid of an injection cannula (needle).

Assignee: Fresenius Kabi Deutschland GmbH (Bad Homburg V.D.H., DE)
Application Number:10/575,690
Patent Claims: 1. A connector for medical liquid-containing packages, in particular infusion or transfusion bags, comprising: a connection part, which has a channel-shaped recess in which a self-sealing membrane is arranged, whereby the channel-shaped recess has a package-side lower opening and a connection-side upper opening; a break-off part, which closes the channel-shaped recess and is connected to the connection part above the connection-side opening; wherein the connection part comprises a connection piece extending above the self-sealing membrane, whereby the self-sealing membrane is slit so as to receive the conical shaft of a syringe in a sealing fashion and wherein the connection piece and the self-sealing membrane of the connection part are designed and arranged in such a way that the conical shaft of a syringe inserted into the connection-side opening opens the slit membrane, but does not penetrate the slit of the self-sealing membrane.

2. The connector according to claim 1, wherein the connection piece of the connection part is designed as a female Luer connector with an internal cone.

3. The connector according to claim 2, wherein the Luer connector of the connection part is designed as a female Luer lock connector with an internal cone and an external thread.

4. The connector according to claim 1, wherein the break-off part is connected via an annular rupture zone to the connection part.

5. The connector according to claim 1, wherein the connection part comprises a lower section and an upper section, whereby the sections are fixed in a snap-in fashion.

6. The connector according to claim 5, wherein the self-sealing membrane is held clamped between the lower and upper section.

7. The connector according to claim 1, wherein the self-sealing membrane has a lower annular portion and an upper plate-shaped portion, which has a mould-shaped recess.

8. The connector according to claim 7, wherein the upper plate-shaped portion is followed by a middle intermediate piece, which transforms into the lower annular portion of the self-sealing membrane.

9. The connector according to claim 7, wherein the annular portion of the self-sealing membrane is clamped between the lower and upper section of the connection part.

10. The connector according to claim 7, wherein the connection part has a shoulder projecting inwards, on which the annular portion of the self-sealing membrane rests.

11. The connector according to claim 7, wherein the connection part has a shoulder projecting inwards, on which the plate-shaped portion of the self-sealing membrane rests.

12. The connector according to claim 11, wherein the plate-shaped portion of the self-sealing membrane is prestressed in a spring-like manner against the shoulder projecting inwards.

13. The connector according to claim 7, wherein the annular portion of the self-sealing membrane is connected in a keyed manner to the lower section of the connection part.

14. The connector according to claim 7, wherein the inner diameter of the annular portion of the self-sealing membrane is smaller than the inner diameter of the channel-shaped recess of the connection part.

15. The connector according to claim 1, wherein the break-off part is designed as a flat grip.

16. A package for medical liquids, in particular infusion or transfusion bags, with a connector according to claim 1.

17. A connector for medical liquid-containing packages, in particular infusion or transfusion bags, comprising: a connection part, which has a channel-shaped recess in which a self-sealing membrane is arranged, whereby the channel-shaped recess has a package-side lower opening and a connection-side upper opening; a break-off part, which closes the channel-shaped recess and is connected to the connection part above the connection-side opening; wherein the connection part comprises a connection piece having an internal cone and extending above the self-sealing membrane, whereby the self-sealing membrane is slit so as to receive the conical shaft of a syringe in a sealing fashion.
