基于连续光谱分析的微型生化分析仪及临床试验

Microbiochemical Analyzer Based on Continuous Spectrum and Its Test for Clinic Use

介绍了一种基于连续光谱分析的微型生化分析仪及其相应的临床试验。该微型生化分析仪采用后分光设计，具有杂散光小、连续光谱（340～770nm）实时测量、体积小、重量轻、样品和试剂消耗量小、检测快速直观等优点，在急诊、中小医疗机构和战地救护、医学研究中有很好的应用前景。试验中选取了临床检验中具有代表性的检测项目（如尿酸，总胆固醇和血清白蛋白等），以医院当日的检验标本为试验样本，与医院的标准生化分析仪器（OlympusAU2700全自动生化分析仪、美国雷杜公司半自动生化分析仪RT-1904C，Beckman公司LX-20全自动生化分析仪）进行对比测试和分析。试验结果表明，该微型生化分析仪器已达到临床应用的要求。

A microbiochemical analyzer based on continuous spectrum and its test for clinic use are introduced. The principle of splitting behind was adopted to design the micro biochemical analyzer, which has the characteristics of little disorder light, real time collection of continuous spectrum signal（340-770 nm）, small volume, light weight, small wastage of sample and reagent and rapidness and direct view of check. It has wide application in the emergency treatment, middling and small hospitals, rescue of battleground, and medicinal research. Representative items for clinic test were selected, such as uric acid, total cholesterin and albumin in our experiments. Comparative test and analysis o{ the daily check-up samples were made respectively by our microbiochemical analyzer and by the standard one of the hospital （Olympus AU2700, RT- 1904C, Beckman LX-20）. The test results show that our micro biochemical analyzer can meet the requirement of clinic use.
