    • A single sampling tube is inserted into a whole blood sample contained in a sample cup, and the blood introduced into a switch-valve and a first channel without being diluted. The switch-valve has a volumetric section. In the first channel are arranged a plurality of ion-sensing electrodes, and downstream from these electrodes, a sample position sensor. The blood is led up to where the sample position sensor is located, at which point it fills the volumetric section and the ion sensing electrode channels. The sample Na.sup.+, K.sup.+, Cl.sup.-, and Ca.sup.++ are detected in this state. After the switch-valve switches, the flow within the volumetric section is forced towards a photometer positioned in a second channel by a reagent solution. The blood is diluted while passing through a reaction coil, during which time enzymes in the blood give rise to enzyme reactions with the reagents. The absorbance of the reaction solution is measured by the photometer.
    • 将单个采样管插入到包含在样品杯中的全血样品中,并且将血液引入开关阀和第一通道而不被稀释。 开关阀具有容积部分。 在第一通道中布置有多个离子感测电极,并且在这些电极的下游布置有样品位置传感器。 血液被引导到样品位置传感器所在的位置,此时它将填充体积部分和离子感测电极通道。 在该状态下检测到样品Na +,K +,Cl-和Ca ++。 在开关阀切换之后,容积部分内的流量被试剂溶液强制位于第二通道中的光度计。 血液在通过反应线圈时被稀释,在此期间,血液中的酶会与试剂引起酶反应。 通过光度计测量反应溶液的吸光度。

    • An automatic analyzer capable of performing analysis in terms of a number of analysis items with high reliability through a simple operation. The automatic analyzer comprises a probe adapted to be moved on a circular arc path and capable of sucking or discharging a sample or reagent, a plurality of sample containers disposed at different positions on the path of the probe and containing different analyte samples, and a rotor capable of carrying a plurality of reagent cartridges. Each of the reagent cartridges comprises a photometric cuvette that is empty when not in use, and a reagent cuvette in which a reagent used for a particular analysis item is hermetically sealed. A two-dimensional code with information regarding the analyte type and analysis conditions, for example, is affixed to the reagent cartridge. The two-dimensional code information is read by a reading unit. Based on the information read from the reagent cartridge, a control unit identifies the sample container in which a analyte sample required by a particular reagent cartridge is contained, and causes the probe to be moved to that sample container. The sample in the sample container is sucked and then discharged into the photometric cuvette of the reagent cartridge. The control unit also causes the probe to suck the reagent in the reagent cuvette of the reagent cartridge and then causes the reagent to be discharged into the photometric cuvette.
    • 一种能够通过简单的操作以高可靠性对多个分析项进行分析的自动分析装置。 自动分析仪包括适于在圆弧路径上移动并能够抽吸或排出样品或试剂的探针,设置在探针路径上的不同位置并包含不同分析物样品的多个样品容器和转子 能够携带多个试剂盒。 每个试剂盒包括不使用时为空的测光反应杯,其中用于特定分析项目的试剂被密封的试剂试管。 例如,具有关于分析物类型和分析条件的信息的二维码被附加到试剂盒。 二维码信息由读取单元读取。 基于从试剂盒读取的信息,控制单元识别其中容纳特定试剂盒所需的分析物样品的样品容器,并使探针移动到该样品容器。 将样品容器中的样品吸入,然后排出到试剂盒的测光反应杯中。 控制单元还使探针吸取试剂盒的试剂池中的试剂,然后使试剂排出到测光反应杯中。
