  • Publication number: 20240139390
    Abstract: The present invention relates to a dialysis machine comprising a balancing system that has at least one balancing chamber for a volumetrically exact supply and removal of dialysis solution to and from a dialyzer fluidically connected to the balancing system in operation; a water inlet system connected to the balancing system for the supply of fresh dialysis liquid, with the water inlet system having an apparatus for degassing water that is connected to an air separator of the dialysis machine, with a first subsection of the air separator serving as a mixing chamber and being connectable to at least one concentrate source via at least one concentrate line and being in fluid communication with the balancing system via at least one dialysate line, wherein the filling volume of a balancing chamber corresponds to or exceeds the sum of the volume of the mixing chamber and the inner volume of the dialysate line.

  • Patent number: 10729837
    Abstract: A dialysis machine has a dialyzer (D), a water inlet system for supplying the dialyzer (D) with fresh dialysis fluid which is connected to the dialyzer and an external water supply and with a line for used dialysis fluid, which is in communication with the dialyzer (D). The water inlet system includes a container for water or other liquid, in particular for RO water. The dialysis machine includes a heat exchanger connected with the line for used dialysis fluid and with the water inlet system so that heat is transferred from the used dialysis fluid to the liquid present in the water inlet system. The container includes means for physical separation of the external water supply and the downstream portions of the water inlet system, preferably a free-fall path for incoming liquid from the water supply, and the heat exchanger is arranged downstream of the container.

  • Patent number: 9782528
    Abstract: A container for dialysis concentrates, in particular acidic dry concentrates, has integral supporting elements. When these dry concentrates are dissolved directly by a dialysis machine to form liquid concentrates, the container must provide a volume of 4-12 liters. To impart the required stability to the container, the container includes the integral supporting elements, which manifest their supporting function only when the container is used on the dialysis machine.
