  • Device with a pumping device for testing the operational capability of a gas guide element of a gas-measuring system
    Patent number: 10712324
    Abstract: A device (1) includes a pumping device (7) and a control unit (70) and is configured to test the operational capability of a gas guide element (3) in a gas-measuring system (11) that includes a gas sensor (5). The control unit (70) carries out steps with two operating states including delivering a test gas (91) by the pumping device (7) through the gas guide element (3) to a remote measuring location (80) and is subsequently delivered from the measuring location (80) to the gas sensor (5). Measured values of a gas concentration are detected by the gas sensor (5) during the delivery from the remotely located measuring location (80) to the gas sensor (5) and analyzed to determine whether changes occurring in the detected gas concentration during the delivery from the measuring location (80) to the gas sensor (5) indicate whether the gas guide element (3) is capable of operating.

  • Method and device for automatic tube transposition detection in a ventilator or anesthesia device
    Patent number: 10702668
    Abstract: A ventilator or anesthesia device and method create a reference state and record a measured value as a reference value. A gas delivery unit is activated after the ending of the reference state to build up pressure in a breathing circuit. A comparison measured value is determined with a pressure or flow sensor. A deviation of the measured value from the reference value in relation to a predefined or predefinable expected value is monitored based on the comparison. A warning message is issued depending on a result of the comparison. A drop in pressure in the breathing circuit is caused after the recording of the comparison measured value and a further comparison measured value is recorded following the drop in pressure. A deviation of the further comparison measured value from the reference value leads to a further warning message when the deviation does not correspond to the further expected value.

  • Testing device for testing a gas guide element
    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).
