  • Dialysis machine with a device for preparing dialysis solutions
    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.

  • Patient connector for peritoneal dialysis
    Patent number: 6482189
    Abstract: A connector for use in peritoneal dialysis, includes a base body having a first tube for attachment of a container for dialysis solution, and a second tube for attachment of a peritoneal catheter. Positioned in a passageway between the first tube and the second tube is a closure piece which so interacts with an actuator that an operation of the actuator causes the closure piece to move in a linear direction from a first position into a second position in which the fluid flow between the first tube and the second tube is closed while the first tube is sealed off.
