  • the invention relates to a container and a hose line with such a device.
  • DE-A-197 28 775 describes an infusion bag with an injection part and a removal part.
  • the injection part is intended for supplying a medicament by means of a syringe, while the extraction part serves to remove the solution by means of a spike.
  • the injection and removal part have a tubular connection part which is closed by a protective cap designed as a break-off part.
  • conical connections with a conical shaft and a conical sleeve are known in medical technology whose conical surfaces are normalized.
  • the non-lockable conical connections with normalized conical surfaces are referred to as Luer connectors and the lockable conical connections as Luer-Lock connectors.
  • the conical luer or luer lock connectors are referred to as male connectors and cones with conical hulls as female connectors.
  • An infusion bag with connectors for supplying and removing liquids is also known from DE-A-103 48 016.
  • the connector for supplying a liquid allows the connection of a conventional syringe with a conical connection, in particular a luer-lock conical connection, which does not have a hypodermic needle. Since an injection needle with a small cross-section is not required, agents of greater viscosity can be injected quickly. For the nursing staff there is no risk of injury. There is also no risk that the infusion bag is injured. The possibility of screwing the syringe and connector ensures that the connection does not break loose.
  • the connector has a self-sealing, slotted membrane that is pierced by the cone shank of the syringe. After pulling out the conical shank, the membrane closes again and thus prevents leakage of the liquid from the bag.
  • the connector has proven itself in practice. Proper functioning of the known connector requires, however, that the membrane can be opened easily and safely.

L'invention concerne également un contenant et un tuyau flexible doté d'un tel dispositif. Le dispositif selon l'invention dispose d'un élément de raccordement (2) qui se raccorde au contenant ou au tuyau flexible et qui présente un évidement (3) dans lequel est placée une membrane (12) qui permet de fermer l'évidement de type canal. Dans l'évidement (3) de l'élément de raccordement (2), un corps creux (22) doté d'une pointe (23) est disposé de telle façon que la membrane (12) est percée lors du raccordement de la seringue à l'élément de raccordement. Le dispositif selon l'invention est caractérisé en ce que la membrane (12) située dans l'évidement (3) de l'élément de raccordement (2) est disposée au-dessus du corps creux (22) de telle façon que lors du raccordement de la seringue à l'élément de raccordement, la membrane est appuyée sur la pointe du corps creux.
