  • 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: 11207513
    Abstract: The invention relates to a connecting piece for establishing a fluid connection between fluid-conducting lines for installation in a cut-out in a housing part of a medical device, in particular a dialysis unit. Furthermore, the invention relates to a medical device, in particular a dialysis unit, comprising a housing that comprises a housing part having a cut-out into which a connecting piece of this type is inserted. The connecting piece 13 according to the invention comprises a tubular body 18 that is made of an electrically conductive material and can be inserted into the cut-out 23 in the housing part 1A, the end pieces 19, 20 of which body are designed for the attachment of the fluid-conducting lines. The connecting piece 13 is distinguished by a terminal part 16 for attaching an electrical protective conductor or equipotential bonding system, the terminal part 16 being electrically conductively connectable or connected to the tubular body 18.
