摘　　要：呼吸率是呼吸功能的一个重要参数,实时监测呼吸率对发现和预防呼吸疾病有着重要意义。设计了一种基于电磁感应自驱动呼吸气流传感器的呼吸率监测系统,该系统将传感器置于口腔/鼻下通过监测呼吸气流的变化来监测人体的呼吸率。实验测得传感器在呼吸缓慢、呼吸正常、呼吸急促时周期分别为3.8,2.3,1.6 s,小于人呼吸周期时间(3~6 s),系统采用蓝牙通信技术传输数据,方便测试者移动。该系统实现了对人体呼吸率稳定、实时、准确的采集,为后续呼吸疾病的预防和诊断提供了一定的研究价值。Respiratory rate is an important parameter of respiratory function,real-time monitoring of respiratory rate is of great significance for the detection and prevention of respiratory diseases.A self-driven respiratory airflow sensor based on electromagnetic induction is designed.The sensor is placed under the mouth/nose to monitor the respiratory rate of the human body by monitoring the changes of respiratory airflow.The sensor has a period of 3.8 s,2.3 s and 1.6 s respectively in slow breathing,normal breathing and rapid breathing,which is less than the human breathing cycle time(3~6 s).The system uses Bluetooth communication technology to transmit data,which is convenient for the test subjects to move.The system realizes stable,real-time and accurate collection of human respiratory rate,which provides certain research value for the prevention and diagnosis of subsequent respiratory diseases.
