  • Patent number: 9592341
    Abstract: The present invention relates to an arrangement for use in a drug delivery device comprising a cartridge holder, the cartridge holder comprising an opening at its distal end, a needle holder and one or more intermediate elements, wherein when the needle holder is mounted to the cartridge holder and the one or more intermediate elements are arranged in the opening of the cartridge holder whereby the size of the free space within the opening is reduced. Furthermore, it relates to a drug delivery device which is comprising such an arrangement and to a method for stabilizing a septum located at the distal end of a medicament cartridge.

  • Patent number: 6743201
    Abstract: A cassette for delivering fluids, especially dialysis fluids, with connecting elements for connecting solution bags and lines leading to the patient for to the dialysis machine, with at least one delivery chamber with an inlet and outlet, with lines for carrying the fluids supplied and delivered, with the walls of the lines being designed at least in some sections so that the lines can be closed by applying a compressive force acting on the walls. Heating and delivery of fluids, in particular dialysis fluids, can be performed effectively and simply by providing at least one area in the cassette where the lines are arranged in such a way that the medium in the lines can be heated to a predetermined set point by means of a heating device arranged outside the cassette.

  • Patent number: 6685831
    Abstract: The present invention relates to a dialysis machine with a device for preparing dialysis solutions. Simple and reliable preparation of dialysis fluids of different concentrations is achieved by the fact that the device has a detector device, at least two connections and at least two interchangeable storage containers to hold the solution ingredients to be metered, each being connected to at least one connector, and with the connectors being connectable to the connections, and with the connectors or the areas of a connecting tube near the connectors having identification means which can be detected by the detector device. The present invention also relates to a connector for connecting a storage container with solution ingredients to a medical apparatus, where the connector or areas of a connecting tube near the connector has identification means. The present invention also relates to a method of detecting a connection of a solution ingredient storage container.

  • Patent number: 6672841
    Abstract: The present invention relates to a pumping device for delivering and metering fluids, in particular medical fluids such as dialysis fluids, with a piston unit having a driving device and a piston and with a membrane unit which has a membrane and a first chamber bordered by the membrane. The pumping device also has a hydraulic unit which has a space to accommodate a hydraulic fluid which is connected to the piston of the piston unit and to the first chamber of the membrane unit. The reliability of metering by such a pumping device is increased by providing a control unit for guaranteeing a predefinable metering rate and/or quantity and also providing a measuring device by means of which the axial position of the piston unit can be determined directly and which can be connected to the control unit.
