    摘要： A device and a process for determining the change in the functional residual capacity (FRC) in a simple manner. Based on a first respiration phase for mechanical respiration, a recruitment maneuver is performed for this during a second respiration phase, and respiration is switched back to mechanical respiration during a third respiration phase. Reference values Uref/1, Uref/3 are formed from the end-expiratory values of the impedance measured signals U during the first respiration phase and the third respiration phase, and the difference ΔU (ΔFRC) between the reference value Uref/3 of the third respiration phase and the reference value Uref/1 of the first respiration phase is an indicator of the change in the functional residual capacity of the lung of the test subject.

    摘要： 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. To further suppress interferences due to common-mode signals, provisions are made for the control and evaluating unit (20) to be set up, furthermore, for detuning the common-mode signal of the alternating current on the body against the ground by means of a common-mode signal measuring electrode (4) and, based on this, the symmetry of the symmetrical AC power source such that the common-mode signal on the body is minimized, and the corresponding detuning parameters are stored for each electrode pair.

    摘要： An electroimpedance tomograph is provided with a plurality of electrodes (1), which can be placed on the body of a patient and are connected to a control and evaluating unit (20) via a selector switch (60). The control and evaluating unit (20) cooperates with the selector switch (60) such that two electrodes each are supplied with alternating current from an AC power source (22). The detected analog voltage signals of the other electrodes are sent into the control and evaluating unit (20) via a measuring amplifier (62) and AD converter (64) and are processed there in order to reconstruct the impedance distribution of the body in the plane of the electrodes therefrom. A symmetrical AC power source (22) is used to reduce common-mode signals. To make it possible to suppress errors due to common-mode signals, provisions are made for the control and evaluating unit (20) to be set up for making available an additional common-mode signal at an output during an adjusting mode of operation and to send it to the body via common-mode signal electrodes (4, 90) that can be placed on the body. The control and evaluating unit (20) is prepared, furthermore, to adjust the measuring amplifier (62) according to value and phase for each electrode pair connected by the selector switch (60) such that the common-mode signal at the output of the measuring amplifier (62) is minimized, and the adjusted parameters are stored for each electrode pair.

    摘要： A compressed air respirator with prolonged operating time due to rebreathing. The compressed air reservoir includes a compressed air reserve with a connected demand air supply valve, a reversible breathing gas reservoir (4) with a registering device (5) detecting the filling level of the breathing gas reservoir (4), and with an inspiration and expiration line (7, 8) for the user of the apparatus. A valve (6) is connected with the inspiration and expiration line (7, 8) and, on the inlet side, with the compressed air reserve (1) with a demand air supply valve (2) and with the breathing gas reservoir (4) and, on the outlet side, with the ambient air (11) and with the breathing gas reservoir (4). The valve means (6) is cyclically reversed by the registering device (5) in two phases such that depending on the filling level of the breathing gas reservoir (4), the inspiration line (7) is first connected with the compressed air reserve (1) and the expiration line (8) with the breathing gas reservoir (4) during a first phase until the filling level of the breathing gas reservoir (4) reaches an upper reversing point for the valve means (6), so that the inspiration line (7) is connected with the breathing gas reservoir (4) and the expiration line (78) with the ambient air (11) during a second phase until the filling level of the breathing gas reservoir (4) reaches a lower reversing point for the valve means (6) and the latter is again reversed as in the first phase.

    摘要： An optical absorption measuring instrument for determining the percentage of a component in a fluid shall be improved such that changes in the measuring radiation caused by drift or temperature have only a limited effect on the measuring result. Provisions are made for deflecting the measuring beams (10, 11) from a radiation source (4) to a detector (5) by at least two plane mirrors (71, 72), which are positioned such that the measuring beams (10, 11) emitted by the radiation source (4) are deflected to the detector (5). The surface of each plane mirror (71, 72) is dimensioned to be such that its illuminated surface in the area of the detector (5) is larger than the receiving surface (12) of the detector (5).

    摘要： A codable gas detection system with at least one interchangeable gas sensor (2), which has standardized plug-type connections (5,6) between the gas sensor (2) and the measuring device (1), but is also able to prevent measured values of an unauthorized gas sensor (2) from being processed. Each gas sensor (2) contains a memory (3) with gas sensor-specific data and is connected via a line to the measuring device (1) with a first calculating and evaluating unit (7), to a downstream memory (8) and preferably to an alarm device (10). Via the second plug-type connection (5), the sensor element (4) proper is connected to a contacting unit (9) in the measuring device (1), and the contacting unit (9) is connected to the first calculating and evaluating unit (7), on the one hand, and to a downstream, second calculating and evaluating unit (11) for the measured value evaluation proper, on the other hand. Measured values from the gas sensor (2) are taken over only if the gas sensor-specific data are accepted by the calculating and evaluating unit (7).
