Embodiment Construction

[0031] The connector according to the invention is designed as an infusion for injecting an active substance into a package containing a medical fluid, in particular an infusion bag or a blood transfusion bag. The connector 20 has a connection part 1 with a channel-shaped notch 1c, which in the use state is composed of a lower part part 2 on the packaging side and an upper part part 3 on the connection side. Therefore, the connector 1 has an upper opening 1a and a lower opening 1b. The connector is an injection molded part made of polypropylene.

[0032] The lower part 2 of the connector part 1 has a cylindrical lower part 4 and a cylindrical upper part 5, wherein the inner diameter of the lower part is slightly larger than the inner diameter of the upper part, and the outer diameter of the lower part is slightly smaller than the outer diameter of the upper part . The lower part 4 can be inserted into a tube connection of a film bag and can be welded or glued to the tube con...

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).

Description

technical field [0001] The invention relates to a connector for a package containing a medical fluid, in particular an infusion bag or a blood transfusion bag, for injecting the fluid into the bag. Furthermore, the invention also relates to a packaging for medical liquids, in particular an infusion bag or a blood transfusion bag, having such an infusion. Background technique [0002] WO 96 / 23545 discloses an infusion bag with an injection part and an extraction part. The infusion part is used to infuse medication by means of a syringe with a thin cannula (needle). The injection part comprises a tubular connection part, which is closed by a protective cap designed as a disconnection part. A self-sealing sealing membrane is fitted in the opening region of the connection part. A pierceable septum in the connector prevents the seal from contacting the solution prior to use of the infusion bag. The extraction part for extracting the solution by the lancing element does not ha...
