Patent number: 8408312Abstract: A method of unloading liquid from a reservoir includes deploying a pumping system into a wellbore to a location proximate the reservoir using a cable. The pumping system includes a multi-section motor, an isolation device, and a pump. The method further includes supplying a power signal from the surface to the motor via the cable and sequentially operating each section of the motor to mimic a multi-phase motor, thereby driving the pump and lowering a liquid level in the tubular string to a level proximate the reservoir.Type: GrantFiled: June 7, 2010Date of Patent: April 2, 2013Assignee: Zeitecs B.V.Inventors: Lance I. Fielder, Christian Carstensen, Rik De Doncker, Helge Brauer, Holger Franz, Johannes Schmidt, Benjamin Eduard Wilkosz

Patent number: 8178040Abstract: A medical fluid management apparatus which includes a plurality of processor systems with respectively associated software programs. The fluid management apparatus has a fluid treatment component and/or a fluid source which can be connected to a patient via a fluid line. The processor systems are connected via a data transfer system to a data input apparatus via which an updating of the software programs belonging to the respective processor systems can take place. After actuation of an operating mode switch, a detection system, while taking into account the existing version of the software programs and/or the existing processor systems, determines which software programs have to be loaded via the data input apparatus. The medical fluid management apparatus allows a simple and user-friendly updating of the operating software even with a complex design of the apparatus.Type: GrantFiled: May 10, 2010Date of Patent: May 15, 2012Assignee: Fresenius Medical Care Deutschland GmbHInventor: Helge Brauer

Patent number: 7780620Abstract: A method for determining the hematocrit and/or blood volume during an extracorporeal blood treatment with an extracorporeal blood circuit, in which blood is taken with a blood pump via an arterial cannula and an arterial flexible-tube line and blood is fed back via a venous flexible-tube line and a venous cannula. Pressure is measured in the extracorporeal blood circuit and a change in the hematocrit is determined from a change in the pressure. The respective relationship between hematocrit HKT or blood volume RBV and pressure P in the extracorporeal circuit is stored for various cannula diameters and various blood-flow values. The respective relationship for a given cannula diameter and blood flow is selected. The hematocrit and/or blood volume is determined taking account of the selected relationship.Type: GrantFiled: March 13, 2007Date of Patent: August 24, 2010Assignee: Fresenius Medical Care Deutschland GmbHInventors: Wei Zhang, Helge Brauer, Reiner Spickermann, Carsten Müller

Patent number: 7125393Abstract: A device for carrying fluids for a medical treatment device with two balancing chambers, each having two partial chambers. The filling times of the partial chambers are initially determined using a monitoring device, and then the filling times of the first partial chambers of the first and second balancing chambers, are compared to the filling times of the second partial chambers of the first and second balancing chambers, respectively, to detect leakage or an incomplete filling or discharging of the respective partial chambers.Type: GrantFiled: August 21, 2003Date of Patent: October 24, 2006Assignee: Fresenius Medical Care Deutschland GmbHInventors: Helge Brauer, Walter Ehrenberger, Helmuth Ender, Joachim Noack

Patent number: 6187207Abstract: A method and a device for verifying the proper replacement of a used filter that is divided into two chambers by a membrane in a device for extracorporeal treatment of blood. The verification of whether the filter has been properly replaced with a new filter is performed by a pressure retaining test, which determines whether the membrane of the filter is permeable to gas. In the event the membrane is permeable to gas, it is concluded that the used filter has been replaced by a new filter.Type: GrantFiled: July 19, 1999Date of Patent: February 13, 2001Assignee: Fresenius Medical Care Deutschland GmbHInventor: Helge Brauer
