血液是一氧化碳中毒唯一重要检材。本文基于双波长检测法构建了一套微型化血液中CO含量检测专用仪。该装置以不同波长的LED为光源,PEEK管作为检测通路,辅以光电转换、数据处理、结果显示等组件,以锂电池为电源,整机重量小于500g,样品消耗量小于6μL,有效光程为27mm,可满足临床及刑侦对血中CO含量的现场快速检测需求。 Blood is the only important sample of carbon monoxide poisoning. In this paper, a dual-wavelength detection method to build a set of miniature blood CO content detection instrument. The device uses different wavelengths of LED as the light source, PEEK tube as the detection path, supplemented by photoelectric conversion, data processing, the results show that the components to lithium batteries as the power source, the whole weight less than 500g, sample consumption less than 6μL, the effective optical path For 27mm, to meet the clinical and criminal investigation on the CO content of blood in the field of rapid detection needs.
