An automated system is developed to monitor cardiopulmonary functions during sleep using electrically conductive textiles. The system obviates the need to attach transducers or electrodes to the body surface, and the subject can follow his or her normal daily routine, wearing regular pajamas to bed. Part of the bed sheet consists of electrically conductive textiles under the positions of the head, torso and legs. Respiratory activity and electrocardiograms of diagnostic quality are observed by means of the electrodes while the subject is sleeping. Respiration is sensed by means of electrical capacitance in/around the thorax. Data acquisition and storage are fully automated; thus, the subject's awareness of being monitored is greatly reduced. This system could detect disorders of cardiopulmonary functions at an early stage, if used daily in the home with the concept of chronodiagnosis.
开发了一种自动化系统,利用导电纺织品在睡眠期间监测心肺功能。该系统无需将传感器或电极附着在身体表面,受试者可以像往常一样正常生活,穿着普通睡衣上床睡觉。床单的一部分由位于头部、躯干和腿部位置下方的导电纺织品组成。在受试者睡眠时,通过电极观察到具有诊断质量的呼吸活动和心电图。通过胸部内/周围的电容感应呼吸。数据采集和存储完全自动化;因此,受试者被监测的意识大大降低。如果在家中每天使用并采用时间诊断的概念,该系统可以在早期阶段检测到心肺功能障碍。
