摘要： The present artificial respiration ventilator (10) comprises, inter alia, a flow sensor arrangement (44, 48) for quantitatively detecting a gas flow in a breathing line arrangement (30), comprising a distal flow sensor (48) located farther from the patient end of the ventilation line arrangement (30). and a proximal flow sensor (44) located closer to the patient end of the ventilation line arrangement (30), and has a control device (18) at least for processing measurement signals of the flow sensor arrangement (44, 48), wherein the control device (18) is designed for error detection based on the measurement signals of the distal (48) and/or the proximal sensor (44). According to the invention, the control device (18) is designed to detect an error of the flow sensor arrangement (44, 48) on the basis of a comparison of a change value (62, 76) of a measurement signal (54, 58, 68, 72) of the one flow sensor (44) with a change value (60, 74) of a measurement signal (52, 56, 66, 70) of the respective other flow sensor (48) or/and with a measurement signal (54, 58, 68, 72) of the one flow sensor (44).

摘要： A control system of a respiratory device for the at least supportive-partial artificial respiration of patients, in particular human patients, comprising a respiratory gas conduit arrangement, a pressure changing arrangement for changing the pressure of respiratory gas in the respiratory gas conduit arrangement during the respiratory operation of the respiratory device, and the control system for controlling the respiratory operation of the respiratory device. The control system has a data input for transmitting operational or/and patient data to the control system. The control system is configured to determine a respiratory operating parameter for the operation of the respiratory device selectively by means of a predetermined first data relationship or by means of a predetermined second data relationship that is different from the first data relationship.

摘要： A non-dispersive multi-channel radiation sensor assembly includes a beamsplitter assembly, a first band-pass filter, which has a predefined first bandwidth and has a transmission maximum at a predefined first useful-signal wavelength, a first measurement-radiation useful-signal sensor, which is arranged downstream of the first band-pass filter in the beam path, a second band-pass filter, which has a transmission maximum at a predefined first reference-signal wavelength, a first measurement-radiation reference-signal sensor, which is arranged downstream of the second band-pass filter in the beam path. The beamsplitter assembly has a first irradiation region and a second irradiation region, in which irradiation regions the beamsplitter assembly is irradiated with measurement radiation. The irradiation regions are optically designed in such a way that the beamsplitter assembly deflects, in the first irradiation region, a first part of the measurement radiation onto the first band-pass filter and a second part of the measurement radiation onto the second band-pass filter.
