  • Patent number: 10743818
    Abstract: Reducing noise in a signal is provided. A first filter includes a selectively definable passband for filtering a first signal used in determining at least one patient parameter. A characteristic analyzer detects a characteristic of a second signal and generates a variability measurement value using a series of data values within the second signal over a previously occurring window of time. A filter controller coupled to the characteristic analyzer uses the variability measurement value to define a characteristic of the passband for the first filter and selectively tunes the passband of the first filter according to the defined characteristic. Related apparatus, systems, techniques, and articles are also described.

    Abstract: A device, for the pressure-supported or pressure-controlled ventilation of a patient with reduced spontaneous breathing, has a ventilator unit to supply a breathing air flow composed of cyclical ventilation strokes and a control unit generating a control signal to set a pressure and/or a volume flow of the breathing air flow. An EMG unit generates an EMG signal, which may be used as a basis for generating the control signal as a function of a breath of the patient. A unit for analyzing an EMG signal is provided, which analyzes at least one EMG signal recorded during an already concluded breath of the patient. The control unit is configured such that the ventilator unit control signal can be generated, at least at times, by taking into account the analysis of the EMG signal recorded during an already concluded breath of the patient.

  • Patent number: 10713921
    Abstract: A control device, controlling an alarm output, includes a data network interface, with a signaling interface for outputting a control signal indicating a request for an acoustic and/or optical alarm signal a memory unit and a processor. The data network interface is configured to receive a group message indicating a sender identity and a presence of an alarm state. The memory unit provides a first data set, which indicates a list with potential sender identities, as well as further a second data set, which indicates one or more alarm output time periods. The processor is configured to operate a timekeeping function, and to output the control signal via the signaling interface as a function of an agreement between the sender identity with one of potential sender identities, and as a function of a comparison of a current value of the timekeeping function with data of the second data set.

  • 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.

  • 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.
