Patent number: 10729837Abstract: 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.Type: GrantFiled: September 28, 2016Date of Patent: August 4, 2020Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventors: Andreas Syfonios, Tilman Staeblein, Dirk Huemmer, Peter Kloeffel

Patent number: 9782528Abstract: 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.Type: GrantFiled: June 3, 2013Date of Patent: October 10, 2017Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventors: Klaus Balschat, Alfred Gagel, Dirk Huemmer, Peter Kloeffel, Olaf Nicholas, Tilman Staeblein
