基于智能手机的普及现状,研制一种低成本、便携式的心电监测设备对于随时检查健康状况和实现远程医疗具有重要意义。本论文中设计的装置采用双极胸导联方式,同时采集心电和呼吸两个通道的信号,经放大和A/D转换,再由单片机将数据发送到手机,具有成本低、体积小、低功耗、方便携带等特点。 Based on the popularity of smart phones, developing a low-cost, portable ECG monitoring device is of great significance for checking health status and implementing telemedicine at any time. In this paper, the device designed by bipolar lead chest way, while collecting ECG and respiratory signals of the two channels, amplified and A / D conversion, and then by the microcontroller to send data to the phone, with low cost, small size, Low power consumption, easy to carry and so on.
