Patent number: 9089664Abstract: A medical device has a fluid port (2), a tube (20), a socket (4), which can be connected to the fluid port and to the tube with freely selectable rotation positions. The tube is provided with a transponder (22) and with a writing and reading device for communication with the transponder, which has an antenna (24) in the area of the fluid port. The socket is provided with a coil (5, 6) each, whose axis of rotation is directed essentially coaxially to the axis of rotation about which the relative rotation position of the socket is variable. The two coils are connected by electric lines (8), to which at least one capacitor (9) is connected as a circuit component. The coils, the electric lines and the circuit component form an electric oscillatory circuit for transmitting signals between the writing and reading device and the transponder.Type: GrantFiled: October 26, 2007Date of Patent: July 28, 2015Assignee: Dräger Medical GmbHInventors: Olaf Schermeier, Gerd Wotha, Markus Steeger, Ludger Tappehorn

Patent number: 8099044Abstract: A radio frequency detection system is provided that includes at least two radio frequency detection devices, which have an antenna each with a detection range for a radio frequency identification and detect the radio frequency identification information provided in the detection range. The radio frequency detection system is designed to attenuate a detection range of a detecting radio frequency detection device in the detection range of the at least one other radio frequency detection device by means of a compensation member such that the radio frequency identification cannot be detected by the detecting radio frequency detection device in the detection area of the at least one other radio frequency detection device.Type: GrantFiled: August 23, 2007Date of Patent: January 17, 2012Assignee: Dräger Medical GmbHInventors: Olaf Schermeier, Markus Steeger

Patent number: 7941210Abstract: An electroimpedance tomograph with a plurality of electrodes (1) is provided, which can be placed on the body of a patient and are connected via a selector switch (60) with a control and evaluating unit (20). The control and evaluating unit (20) cooperates with the selector switch (60) such that two electrodes each are supplied with an alternating current from an AC power source (22) and the detected analog voltage signals of the other electrodes are processed in order to reconstruct therefrom the impedance distribution of the body in the plane of the electrodes, wherein a symmetrical AC power source is used to reduce common-mode signals.Type: GrantFiled: June 29, 2006Date of Patent: May 10, 2011Assignee: Dräger Medical GmbHInventors: Hans Matthiessen, Dieter Weismann, Jianhua Li, Yvo Gärber, Arndt Pöcher, Markus Steeger

Patent number: 7711418Abstract: An electroimpedance tomograph including a plurality of electrodes placed on a body, measuring circuits processing voltage signals recorded by the electrodes, and a control unit supplying two electrodes each with an alternating current. The control unit has a preset feed frequency. The control unit processes the processed voltage signals of all other electrodes to reconstruct the impedance distribution of the body in the electrode plane. The control unit provides for an automatic setting of the current feed frequency/frequencies to record a background frequency spectrum by detecting the electrode voltage signals over a preset period of time and record them as a voltage time series and transform them into a frequency spectrum. The control unit searches in the background frequency spectrum for a frequency (different states) or frequencies (different frequencies) that leads to a useful signal to background ratio above a preset threshold value when used as a feed frequency.Type: GrantFiled: June 30, 2004Date of Patent: May 4, 2010Assignee: Dräger Medical AG & Co.

Publication number: 20080173308Abstract: A medical device is provided with a fluid port (2), a tube (20), a socket (4), which can be connected to the fluid port (2), on the one hand, and to the tube (20), on the other hand, with freely selectable rotation positions, in order to establish a fluid connection between the fluid port (2) and the tube (20). The tube (20) is provided with a transponder (22) at its end at which it is connected to the socket (4), and with a writing and reading device for communication with the transponder (22), which has an antenna (24) in the area of the fluid port (2). The socket (4) is provided, in the area of its two connection ends, with a coil (5, 6) each, whose axis of rotation is directed essentially coaxially to the axis of rotation about which the relative rotation position of the socket (4) is variable. The two coils (5, 6) are connected by electric lines (8), to which at least one capacitor (9) is connected as a circuit component.Type: ApplicationFiled: October 26, 2007Publication date: July 24, 2008Applicant: DRAGER MEDICAL AG & CO.

Publication number: 20050059901Abstract: An electroimpedance tomograph is provided with a plurality of electrodes placed on a body, measuring circuits that process the voltage signals recorded by the electrodes, and a control unit that supplies two, preferably adjacent electrodes each with an alternating current. The control unit has a preset feed frequency performed in different states and different preset feed frequencies performed at different frequencies. The control unit processes the processed voltage signals of all other electrodes to reconstruct the impedance distribution of the body in the electrode plane. To make the EIT more insensitive to electromagnetic interferences, the control unit provides for an automatic setting of the current feed frequency/frequencies to record a background frequency spectrum by detecting the electrode voltage signals over a preset period of time and record them as a voltage time series and transform them into a frequency spectrum.Type: ApplicationFiled: June 30, 2004Publication date: March 17, 2005Inventors: Yvo Garber, Markus Steeger, Jianhua Li, Steffen Leonhardt, Jan Ruterbories, Rainer Goldau
