Embodiment Construction

[0041] Figure 1 to Figure 6 A first embodiment of the device of the invention for connecting a syringe to a container is shown. figure 1 with 2 A side view and a cross-sectional view of the device of the present invention are shown, with the syringe not yet attached to the device.

[0042] The device 1 according to the invention is designed as an injection part for injecting an active substance into a container containing a medical fluid, in particular an infusion or injection bag. The device of the invention thus relates to a connector 1 .

[0043] The connector 1 is an injection-molded part made of polypropylene and has a connection part 2 with a channel-shaped recess 3 which, in the use position, consists of a bag-side lower part 4 and a connection-side upper part 5 . The lower part 4 of the connection part 2 has a substantially cylindrical lower section 6 and an upper section 7 , the lower section 6 having a smaller outer diameter than the upper section 7 . The lower se...

Abstract

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.

Description

technical field [0001] The invention relates to a device for connecting a syringe to a container or a glue line, in particular for connecting a syringe to a container for containing infusion solution, injection solution or enteral nutrition solution and especially for connecting the syringe A hose line connected to the vascular system of an extracorporeal blood treatment device or to a hose line for accessing a vein. Furthermore, the invention relates to a container and a glue line with such a device. Background technique [0002] DE-A-197 28 775 discloses an infusion bag with an injection part and an extraction part. The injecting part is used for injecting medicine by means of the injection needle, and the extracting part is used for extracting the solution by means of a sharp needle. The injection part and the extraction part have a tubular connection part, which is closed by a protective cap designed as a disconnection part. [0003] For connecting medical instruments...
