便携式睡眠呼吸暂停血氧监护系统的设计

Design of portable blood-oxygen monitor system on sleep apnea syndromes

目的设计一套可以直接佩戴在患者身上的睡眠呼吸血氧监护系统,监测在呼吸暂停间隙患者是否伴有缺氧和心血管疾病发生。方法以台湾友晶科技公司推出的FPGA开发系统DE2为硬件平台,采用ALTERA公司的可编程片上系统开发工具SOPC Builder完成系统搭建,并在NiosII IDE集成开发环境下完成系统软件开发。采用ALTERA公司的SOPC技术,以DE2开发板为核心,通过检测并收集患者在睡眠过程中的呼吸、血氧饱和度、脉搏以及打鼾次数等信息,判断患者是否存在睡眠呼吸暂停症状。结果经过检测,系统能够确定患者睡眠过程中身体是否出现异常,并在紧急状况时给与告警和刺激。结论该系统具有操作简单、轻便低功耗等特点,采集和检测的所有数据可以同步显示和存储,方便后期跟踪与处理。

Objective A portable blood？oxygen monitor system is design to detect the incidental hypoxia and cardiovascular diseases apnea, which can be adorned on the patients with sleep apnea. Methods With the FPGA developing system DE2 produced by Jingyou Technology Company of Taiwan as the hardware platform,he system is set up using the development tool SOPC Builder, and the systems software is developed in the integrated development environment of NiosII IDE. The SOPC technology of ALTERA Company is adopted, and with the DE2 development board at the core, the system can judge whether there exist sleep apnea by detecting and recording the respiration,oxyhemoglobin saturation, pulse and the frequency of snore. Results The system can determine whether the body is normal or not during sleep, and give an alarm and stimulation in a critical condition. Conclusions The system has the features of simplicity of operator, portability, low power consumption and so on. All the data can be synchronously displayed and saved, it is convenient to tail after and process later.
