Publication number: 20140349146Abstract: A battery (100) has first accumulator cells (111 . . . 114) connected in series to form at least one cell string (110), and second accumulator cells (121 . . . 124) are arranged so that cells can be connected in parallel to individual cells of the first accumulator cells (111 . . . 114) by switching elements (131 . . . 133?, 134, 134?). To compensate the charge between the cells, the switching elements (131 . . . 133?, 134, 134?) can establish two-way connections (A, B) between the first and second accumulator cells. Each second accumulator cell (121) can be connected in parallel alternately either to a first accumulator cell (111) within the cell string (110) or to another adjacent first accumulator cell (112). The switching elements (131 . . .Type: ApplicationFiled: October 16, 2012Publication date: November 27, 2014Applicant: Albright Deutschland GmbHInventor: Ralf Dittmann

Patent number: 7856978Abstract: An anesthesia apparatus with a breathing circuit (1) has improved initiation of anesthesia for the patient. The gas mixture dispensed into the breathing circuit (1) is circulated in a first operating state without release to a patient until a preset anesthetic concentration is set in the breathing circuit (1). The respiration of the patient connected to the anesthesia apparatus takes place in a subsequent second operating state with the gas mixture set in the first operating state.Type: GrantFiled: July 14, 2005Date of Patent: December 28, 2010Assignee: Dräger Medical GmbHInventor: Ralf Dittmann

Patent number: 7703455Abstract: An apparatus for supplying respiratory gas to a patient in which respiratory gas components are metered with great accuracy and sources of error are detected early. The apparatus has metering devices for respiratory gas components which are connected, on the leading side of a mixing chamber volume, to a ring line; a first respiratory gas analyzer on the trailing side of the mixing chamber volume; a second respiratory gas analyzer at a patient connection; a regulating device for the respiratory gas components which controls the delivery of respiratory gas components, as a function of the concentration measured with the second respiratory gas analyzer, in such a way that the difference between a predetermined concentration and a measured concentration at the patient connection is minimized; and means for performing a plausibility comparison between the measured values of the first respiratory gas analyzer and the second respiratory gas analyzer.Type: GrantFiled: August 26, 2004Date of Patent: April 27, 2010Assignee: Dräger Medical AG & Co.

Patent number: 6691705Abstract: An arrangement with a control circuit for controlling a numerical value for patient respiration as well as to a process for controlling the numerical value. The numerical value is controlled on the basis of an evaluation of the EEG (electroencephalogram) of the patient (1) by an EEG sensor (2), e.g., by determining the so-called BIS (bispectral index). A control of the inspiratory gaseous anesthetic concentrations is cascaded to the control of the EEG value in the manner of a cascade circuit. This has the advantage that a metering device (6) belonging to the arrangement meters a gaseous anesthetic mixture directly according to the patient's needs. As an alternative, the control of the numerical value is performed on the basis of an evaluation of the expiratory gaseous anesthetic concentrations resolved for individual breaths at the Y-piece (19) of the respiration circuit (12) by a gaseous anesthetic sensor (8a), preferably an infrared optical gas sensor.Type: GrantFiled: March 22, 2001Date of Patent: February 17, 2004Assignee: Dräger Medizintechnik GmbHInventors: Ralf Dittmann, Swen Grünitz-Post, Steffen Leonhardt, Andrea Gentilini, Adolph Glattfelder, Manfred Morari, Thomas Schnider, Alexander M Zbinden
