  • Patent number: 10661042
    Abstract: An apparatus for supplying breathing air to a person includes a rebreathing system arranged in the air supply circuit, which removes CO2 at least in part present in the person's expiration air with a CO2 absorber, and treats the expiration air to supply treated air to the person again as inhalation air. The apparatus includes a condensate collection container (9) collecting water forming in the air supply circuit. The condensate collection container (9) is arranged at least in part below a reaction zone (17) of the CO2 absorber (1). At least one heat exchanger (10, 14) is provided in the CO2 absorber, via which heat from the air, which flows through the CO2 absorber and is heated as a result of the exothermic CO2 absorption reaction occurring in the reaction zone of the CO2 absorber, is dissipated.

  • Patent number: 10648963
    Abstract: A testing device (1) is configured for testing a gas guide element (3). A control unit (70) carries out a sequence of steps with two operating states. A test gas (91) is delivered by a pumping device (7) through the gas guide element (3) to a remotely located measuring location (80) and is subsequently delivered from the remotely located measuring location (80) to the gas sensor system (5). Measured values (77) are detected and analyzed during the delivery from the remotely located measuring location (80) to the gas sensor system (5) by a sensor (6, 90), which indicates a state of flow in the gas guide element (3) or an operating state of the pumping device (7). Changes occurring in the measured values (77) during the delivery from the remotely located measuring location (80) to the gas sensor system (5) indicate the operational capability of the gas guide element (3).

  • Patent number: 10542900
    Abstract: A device for detecting electric potentials of the body of a patient has measuring electrode inputs (Y1, . . . , Yn) connected with and a plurality of outputs (A1, . . . , An) via amplifiers (Op1, . . . , Opn). A summing unit (13) is connected with the outputs and outputs a mean value of the signals (E1, . . . , En) output by the amplifiers. Common mode signals are removed from the signals (E1, . . . , En) by a subtracting unit (19) which subtracts the output of the summing unit, amplified by an amplification factor (1/?), from at least a portion of the output of the subtracting unit. The output of the subtracting unit is connected with the inputs of the amplifiers. The subtracting unit amplification factor (1/?) and an amplification (??) of the amplifiers for the output of the subtracting unit are adapted, such that the reciprocal value of the amplification factor (1/?) corresponds to the amplifiers amplification (??).

  • Patent number: 10502682
    Abstract: A device (1) for determining the concentration of a gas component is configured with a radiation source (30) for emitting (31) a light radiation or heat radiation in an infrared wavelength range. A detector array (40) has at least two detector elements (50, 60), configured to detect the radiation generated by the radiation source (30), in an angular arrangement (52, 62) and with filter elements (51, 61). At least one of the two detector elements (50, 60) is oriented in an angular arrangement (52, 62) in relation to a vertical axis (32), so that a range of overlap (65) is obtained due to the angular arrangements (52, 62). The range of overlap (65) causes attenuations in the propagation of light, which attenuations may be due, for example, to gas molecules or moisture (400), affect both detector elements (50, 60) and are thus compensated concerning the concentration determination.
