Patent number: 8858493Abstract: A cap, especially a disinfectant cap, is for protecting and/or closing off the abdominal connector used in peritoneal dialysis, and to a detection device for peritoneal dialysis. There is a bag set for peritoneal dialysis and use thereof. In view of the sometimes serious consequences of an incorrect sequence of fluids in the patient's abdominal cavity, it is desirable to prevent an incorrect sequence of fluids during peritoneal dialysis. This is achieved by providing the cap, especially a disinfectant cap, with information about the medium contained at any one time in the patient's abdominal cavity. In this way it is always possible—even after the fluid has been dispensed into the abdominal cavity and the bag disposed of—to determine which medium is currently in the patient's abdominal cavity and/or to record other details, such as the amount, the concentration, the manufacturer, etc.Type: GrantFiled: June 3, 2005Date of Patent: October 14, 2014Assignee: Fresenius Medical Care Deutschland GmbHInventor: Wolfgang Biesel

Patent number: 8523799Abstract: A method for priming a blood tubing set having a venous line and an arterial line whose connections at the patient side are in communication with two separate inlets of a chamber of, in particular, a bag and whose connections at the machine side are in communication with a dialyzer. The method includes the steps of parallel filling of both the venous and the arterial lines via a feed line so that priming liquid flows through both inlets into the chamber; and circulation of the priming liquid in the circuit of the lines, the dialyzer and the chamber via a pump so that one of the inlets of the chamber acts as an inlet and the other as an outlet.Type: GrantFiled: December 19, 2007Date of Patent: September 3, 2013Assignee: Fresenius Medical Care Deutschland GmbHInventors: Wolfgang Biesel, Maria Millan Galante

Patent number: 8038643Abstract: The invention relates to a device for loading a patient connector for peritoneal dialysis with a closure plug. To permit an arbitrary number of disconnection/connection procedures with patient connectors that insert a sterile closure plug into the patient's abdominal connector during disconnection, a device for loading a patient connector for peritoneal dialysis with a closure plug is suggested, said device consisting of a housing containing a closure plug and of means for transferring the closure plug out of the device and into a patient connector. This permits loading, under sterile conditions, of a patient connector whose closure plug has already been used with a new closure plug. By loading a new closure plug, the push-button with which the closure plug is inserted is returned to its starting position, so that the patient connector is again available for a connection/disconnection procedure.Type: GrantFiled: January 27, 2005Date of Patent: October 18, 2011Assignee: Fresenius Medical Care Deutschland GmbHInventors: Wolfgang Biesel, Reinhold Reiter, Alain Veneroni

Patent number: 6964646Abstract: A device for autologous blood transfusion includes a centrifuge unit with an autotransfusion set rotatably mounted thereto. The autotransfusion set includes a separation unit for concentrating a cell fraction by centrifugation and a tubing system for providing a connection to a blood supply. The tubing system includes a blood supply line leading to the separation unit for supplying blood to be processed and a return line leading away from the separation unit. A filter is integrated into the autotransfusion set in order to eliminate leukocytes and/or tumor cells, thereby yielding greater safety in autotransfusion.Type: GrantFiled: August 10, 2000Date of Patent: November 15, 2005Assignee: Fresenius HemoCare GmbHInventor: Wolfgang Biesel

Patent number: 5814279Abstract: A centrifuge has a drive unit, a separation chamber which can be inserted into the drive unit, and a scanning device for recognizing the position of the separation chamber which is rotated by the drive unit. The separation chamber is constructed as a disposable chamber and is provided with a marker element which is arranged in a scanning region extending annularly around the rotation axis of the chamber. The position of a phase boundary window is detected by sensing the position of the marker with a phase boundary detector portion of the scanning device whereby the chamber can be inserted into the drive unit in any position.Type: GrantFiled: February 2, 1996Date of Patent: September 29, 1998Assignee: Fresenius AGInventors: Wolfgang Biesel, Stefan Kreber, Henning Brass, Friedrich Witthaus, Artur Meisberger

Patent number: 5350514Abstract: The invention relates to a centrifuge comprising a separation chamber, with which a duct is permanently connected, a main rotor, on which the separation chamber is able to be bearinged in a relatively rotatable manner with respect to it, by means of a bearing arrangement, and a guide means on the main rotor for guiding the duct from the middle lower part of the separation chamber into a part at a higher level than the centrifuge. In order to be able to introduce the separation chamber into the main rotor in a simple and controlled manner the bearing arrangement has, within the main rotor, a part which is open or is able to be opened in a radial direction for the introduction of the duct into the main rotor.Type: GrantFiled: June 18, 1993Date of Patent: September 27, 1994Assignee: Fresenius AGInventors: Friedrich Witthaus, Wolfram Weber, Wolfgang Biesel, Carlo Lay
