基于 Android 的血氧饱和度和脉率检测系统设计

摘要

The measurement of blood oxygen saturation and pulse rate has great significance in people’s routine inspections,but the hospital physicals cost a lot of manpower and material resources.In view of this,the paper proposes an Android platform-based blood oxygen saturation and pulse rate parameters detection system.By analysing the pulse wave data of fingertip it is able to obtain multiple physiological parameters,the control of Bluetooth module by microcontroller is employed to achieve the communication with Android mobile devices and to implement the reception and display of physiological parameters,and in further the data exchange with Baidu cloud database is completed through 3G/4G network.This design overcomes the drawbacks of traditional wired devices in inconvenient moving,brings convenience to patients for their inspection.Experimental results show that to use this method can effectively improve the efficiency,realises remote inspection,and creates conditions for home monitoring and remote medical treatment.%血氧饱和度和脉率的检测在人们常规检查中有着重要意义，医院体检耗费大量人力物力。针对这种情况，提出一种基于Android 平台的血氧饱和度、脉率参数检测系统。通过分析指端脉搏波数据得出多项生理参数，利用单片机对蓝牙模块的控制，实现与 Android 移动设备通信，完成生理参数的接收、显示，并进一步通过3G／4G 网络，完成与百度云端数据库的数据交换。克服了传统有线设备移动不便的缺点，给病人检测带来便利。实验结果表明，采用该方法可以有效提高效率，实现远程监测，为家庭监护、远程医疗创造了条件。
