    • An apparatus for diluting and mixing specimen is an apparatus for mixing luquid specimen such as blood and a reagent, which is designed to prepare a mixed solution of a specimen and a reagent at a specific ratio by discharging the reagent in the passage (P2) for quantitative determination in the sampling valve (10) by a specified amount of the reagent. In this apparatus for diluting and mixing specimen, when discharging the specimen by the reagent, it is designed to discharge the specimen at low speed by the reagent discharge means until it comes out of the sampling valve (10), and then discharge at usual speed thereafter. As the reagent discharge means, syringe (C2), pump (C'2) having thin film such as diaphragm and others may be used. By thus constituting, the specimen is free from damage due to fluid pressure.
    • 用于稀释和混合样品的装置是用于混合诸如血液和试剂的液体试样的装置,其被设计成通过将通道(P2)中的试剂排出以特定比例制备样品和试剂的混合溶液,用于 在取样阀(10)中用一定量的试剂进行定量测定。 在这种用于稀释和混合试样的装置中,当通过试剂排出试样时,其被设计成通过试剂排放装置以低速排出试样,直到其从取样阀(10)中排出,然后以通常的速度放出 其后。 作为试剂排出装置,可以使用具有膜等薄膜的注射器(C2),泵(C'2)等。 通过这样构成,样品不会因流体压力而损坏。
