摘要
个体化医疗事业的发展对微型、低成本医疗诊断产品的需求日益增加。为实现对人体呼吸率的长时监测从而对睡眠、呼吸障碍等加以评估,本文基于将数据记录与解读环节完全分离的飞机黑匣子理念,研制出采用廉价T型热电偶记录温度以反映人体呼吸率的超低成本记录卡,可以更方便、更长时间的对呼吸温度数据及时间信息进行采集和事后评估。通过与商业化Agilent数据采集仪的呼吸频率对比监测实验表明,该记录卡可以较好地获取呼吸频率信息,且易于通过USB接口再现于计算机屏幕。本文工作为建立低成本化呼吸诊断提供了重要而现实的技术途径。
Along with the development of personalized health care, the demand for miniturized or low cost medical devices is increasing. In order to realize a long term monitoring of breathing rate and thus diagnose the sleeping or breathing disorders, an ultra low cost breathing rate recording card (BRC) adopting the easily available type-T thermocouple as temperature sensor was developed, following the concept of dark casket in flight so as to separate the data recording and unscrambling procedures. The BRC system allowed to record and evaluate afterwards the breathing temperature data and time information via a more convenient and durable way. Through the contrast experiment on breathing rate detection between BRC and commercial Agilent Data Acquisition System, it was demonstrated that the breathing rate information could be easily obtained by the BRC and displayed on the computer screen via the USB interface. This study provides a significant and realistic technical approach for low cost breathing diagnostics.
