Title:
フローセンサのためのエラー検出器を備えた人工呼吸器
Document Type and Number:
Japanese Patent JP6840736
Kind Code:
B2
Abstract:
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).
