Patent number: 9662430Abstract: The invention relates to a device and a method for conveying a fluid to a filter unit of a medical treatment apparatus, in particular for conveying a dialysing fluid to a treatment unit, in particular a dialyser or filter of an extracorporeal blood treatment apparatus. The device comprises a balancing unit and a recirculation unit, which comprises one or more chambers. With the balancing unit, it is possible to supply fresh fluid continuously to the recirculation circuit and to discharge used fluid from the recirculation circuit. The supply and discharge of fresh and used dialysing fluid can take place at a flow rate other than the flow rate at which the fluid circulates in the recirculation circuit via the filter unit.Type: GrantFiled: April 13, 2012Date of Patent: May 30, 2017Assignee: Fresenius Medical Care Deutschland GmbHInventors: Stefan Kreber, Manfred Weis

Patent number: 9603987Abstract: The present invention relates to a device and method for conveying fluids into the treatment unit of a medical treatment apparatus. The device and method according to the present invention are based on the fact that the fluid with which the treatment unit is supplied, circulates in a fluid circuit including the treatment unit. To balance fresh and used fluid fed to the treatment unit or conveyed from the treatment unit, a balancing unit with a balancing chamber is used, which can be incorporated into the fluid circuit including the treatment unit. It is thus possible to supply the fluid circuit continuously with fresh fluid or to carry away used fluid continuously from the fluid circuit. The supply and discharge of fresh and used fluid can take place at a different flow rate from the flow rate at which the fluid circulates in the fluid circuit via the treatment unit.Type: GrantFiled: June 14, 2011Date of Patent: March 28, 2017Assignee: Fresenius Medical Care Deutschland GmbHInventors: Matthias Brandl, Manfred Weis, Volker Nier, Gerhard Mager, Michael Herrenbauer

Publication number: 20160325034Abstract: The present invention relates to the field of regulating and presetting pump rates of blood pumps. It is directed at a device and a method in which the blood pressures are monitored upstream and/or downstream from the blood pump, and these values or another value formed from these values are compared with a limit value, which depends on an operating parameter or a pump parameter on the blood pump. In violation of the limit value, the pump rate of the blood pump is modified to such an extent or a new pump rate is determined so that the limit value is no longer violated or the degree of violation is reduced.Type: ApplicationFiled: January 21, 2015Publication date: November 10, 2016Applicant: Fresenius Medical Care Deutschland GmbHInventors: Christoph WIKTOR, Arne PETERS, Alexander HEIDE, Manfred WEIS
