The invention relates to a device for connecting a syringe to a container or tubing, particularly for connecting a syringe to a container for receiving infusion-, transfusion-, or enteral nutrition solutions and particularly for connecting a syringe to tubing of a blood tube system of an extracorpor
The invention relates to a device for connecting a syringe to a container or tubing, particularly for connecting a syringe to a container for receiving infusion-, transfusion-, or enteral nutrition solutions and particularly for connecting a syringe to tubing of a blood tube system of an extracorporeal blood treatment device or to tubing for a venous portal. The invention also relates to a container and tubing with such a device. The device according to the invention has a connecting part (2) which connects to the container or the tubing, the connecting part having a recess (3) in which a membrane (12) is arranged, the membrane closing the channel-shaped recess. A hollow body (22) having a syringe (23) is arranged in the recess (3) of the connecting part (2) in such a manner that the membrane (12) is pierced upon connection of the syringe to the connecting part. The device according to the invention is characterized in that the membrane (12) is arranged above the hollow body (22) in the connecting part (2) recess (3), such that upon connection of the syringe to the connecting part, the membrane is pressed onto the tip of the hollow body.

1. An apparatus comprising a connector for connecting a syringe to a container or tubing, wherein the connector comprises a connecting part having an upper end, wherein the connecting part is to be connected to the container or the tubing,wherein the connecting part has a recess in which a membrane
1. An apparatus comprising a connector for connecting a syringe to a container or tubing, wherein the connector comprises a connecting part having an upper end, wherein the connecting part is to be connected to the container or the tubing,wherein the connecting part has a recess in which a membrane is arranged;a break-off part that closes the recess of the connecting part and is connected to the upper end of the connecting part;wherein the break-off part comprises a tamper-evident closure, and a hollow body with a point that is arranged in the recess of the connecting part,wherein the membrane and the hollow body are arranged in the recess of the connecting part in such a manner that the membrane is pierced when the syringe is connected to the connecting part,wherein the membrane is arranged above the hollow body in the recess of the connecting part and therefore, when the syringe is connected to the connecting part, the membrane is pressed by the syringe onto the point of the hollow body, andwherein the membrane and the hollow body are arranged at a non-zero distance from each other in the recess of the connecting part,wherein the break-off part has an unbroken state and a broken state,wherein in the unbroken state the break-off part is an unbroken break-off part,wherein in the broken state the break-off part is a broken break-off part,wherein the break-off part is configured to transition from the unbroken state to the broken state,wherein a transition from the unbroken state to the broken state permits a liquid connection between the syringe and the connector. 2. The apparatus of claim 1, wherein the hollow body comprises a cannula that comprises a ground section. 3. The apparatus of claim 2, wherein the hollow body in the recess of the connecting part is fastened to a disk-shaped body that comprises openings. 4. The apparatus of claim 3, wherein the connecting part consists of a lower subsection and an upper subsection that are fixed by clicking into place, wherein the disk-shaped body is arranged at an upper end of the lower subsection. 5. The apparatus of claim 4, wherein the membrane has an upper, plate-like portion that is adjoined by an annular, lower portion. 6. The apparatus of claim 5, wherein the lower, annular portion of the membrane is held clamped between the lower subsection and the upper subsection of the connecting part. 7. The apparatus of claim 3, wherein the openings in the disk-shaped body comprise bores that are distributed circumferentially around the hollow body. 8. The apparatus of claim 4, wherein the membrane is held clamped between the lower subsection and the upper subsection of the connecting part. 9. The apparatus of claim 1, further comprising a container for medicinal liquids, wherein the connecting part of the connector is connected to the container. 10. The apparatus of claim 9, wherein the container comprises a bag, wherein the bag is selected from the group consisting of an infusion bag, a transfusion bag, and a bag for holding an enteral nutrient solution, wherein the connecting part of the connector comprises a closure part that is welded to the bag. 11. The apparatus of claim 9, wherein the container comprises a bag, wherein the bag is selected from the group consisting of an infusion bag, a transfusion bag, and a bag for holding an enteral nutrient solution, wherein the connecting part of the connector comprises a closure part that is adhesively bonded to the bag. 12. The apparatus of claim 1, wherein the membrane is slit in order to receive a tapered shaft of the syringe in a manner that maintains a seal around the tapered shaft of the syringe. 13. The apparatus of claim 1, wherein the connecting part has an external thread for the connection of a Luer Lock syringe. 14. The apparatus of claim 1, wherein an upper side of the membrane comprises a trough-shaped depression. 15. The apparatus of claim 1, wherein the break-off part as comprises a flat gripping piece that is connected to the upper end of the connecting part via an annular breaking zone. 16. The apparatus of claim 1, further comprising the syringe, wherein the syringe further comprises a tapered shaft. 17. The apparatus of claim 1, wherein the non-zero distance is sufficient to prevent unintentional piercing of the membrane. 18. The apparatus of claim 1, wherein the non-zero distance is selected to define a gap within the recess, wherein the gap within the recess extends across a portion of the recess that is between the hollow body and the membrane. 19. The apparatus of claim 1, wherein, as a result of having made a transition from the unbroken state to the broken state, the break-off part is precluded from making another transition from the unbroken state to the broken state.
