Foetal breathing movement (FBM) in utero has come to play an important role in foetal diagnosis. FBM may be monitored using real time ultrasound imaging of the foetus in utero. Foetal breathing activities can also be detected by monitoring maternal abdominal wall movement in the frequency range of 0.5-2.5 Hz. This paper presents a transducer which detects FBM non-invasively by monitoring maternal abdominal wall movements. Foetal heart sounds can also be monitored. The transducer presented uses piezo-electric film as the transducing medium. Results from preliminary clinical trials of prototype transducers on 10 patients are discussed.
子宫内的胎儿呼吸运动(FBM)在胎儿诊断中已发挥重要作用。可以使用子宫内胎儿的实时超声成像来监测FBM。胎儿呼吸活动也可以通过监测频率范围为0.5 - 2.5赫兹的孕妇腹壁运动来检测。本文介绍了一种通过监测孕妇腹壁运动以无创方式检测FBM的传感器。胎儿心音也可以被监测。所介绍的传感器使用压电薄膜作为传感介质。讨论了该原型传感器在10名患者身上进行的初步临床试验结果。
