Abstract

A unique clinical chemistry analyser is described which processes 90 mul of whole blood (fingerstick or venous) into multiple aliquots of diluted plasma and reports the results of 12 tests in 14 min. To perform a panel of tests, the operator applies the unmetered sample directly into a single use, 8 cm diameter plastic rotor which contains the required liquid diluent and dry reagents. Using centrifugal and capillary forces, the rotor meters the required amount of blood, separates the red cells, meters the plasma, meters the diluent, mixes the fluids, distributes the fluid to the reaction cuvettes and mixes the reagents and the diluted plasma in the cuvettes. The instrument monitors the reagent reactions simultaneously using nine wavelengths, calculates the results from the absorbance data, and reports the results.

离心和毛细管集成到一个多分析全血分析仪。
描述了一种独特的临床化学分析仪,它将90多毫升全血(手指或静脉)处理成多个等分稀释血浆,并在14分钟内报告12项测试的结果。为了执行一系列测试,操作员将未计量的样品直接放入一次性使用的直径8厘米的塑料转子中,转子中包含所需的液体稀释剂和干试剂。转子利用离心力和毛细力,计量所需的血量,分离红细胞,计量血浆,计量稀释剂,混合液体,将液体分配到反应试管中,并将试剂和稀释后的血浆混合在培养皿中。仪器使用9个波长同时监测试剂反应,从吸光度数据计算结果,并报告结果。
