论文摘要
脉搏波的测量已被证明是医学诊断中的重要工具。因此，大多数脉搏波测量是在四肢进行的，这项工作提出了一个用于测量脉冲波和脉冲到达时间（PAT）的系统。开发的测量设备基于电池供电的微控制器系统。测量设备可以同时获得单个通道心电图（ECG），双波长光清理图（PPG），两只耳朵的压力，体内核心温度以及受试者运动。获得的测量数据可以保存在微型SD卡上，也可以通过蓝牙传输无线或通过USB连接到主机PC以进行进一步分析。在蓝牙通信模式下，设备可以操作最多8小时的电池。除了系统描述外，还将提出对系统进行的首次测量。
The measurement of the pulse wave has proven to be a vital tool in medical diagnosis. Whereby most pulse wave measurements are carried out at extremities, this work proposes a system for measuring the pulse wave and the Pulse Arrival Time (PAT) in the interior of the ear. The developed measurement device is based on a battery powered microcontroller system. The measurement device can simultaneously acquire a single channel Electrocardiogram (ECG), a dual wavelengths Photoplethysmogram (PPG), the pressure in both ears, the body core temperature, as well the subjects motion. The acquired measurement data can either be saved on a micro SD-card or can be transmitted wireless via Bluetooth or wired via USB to a host PC for further analysis. In Bluetooth communication mode the device can operate battery powered up to 8 hours. In addition to the system description, first measurements carried out with the system will be presented.
