    • A sampling valve comprises two fixed elements, and a movable element held between these fixed elements, in which a flow-in passage (Q) is provided at one fixed element so as to communicate with at least one of the metering passages (P1) , . . . . Plural flow-out passages (R1), (R2), . . . are provided at the other or one fixed element so as to communicate with different metering passages individually. Relay passages (S1), . . . are also provided at the one or other fixed element so as to mutually connect the metering passages (P1), (P2), . . . in specified combinations. In such a construction, plural sampling routes are formed in the sampling valve. In the sampling valve for aspirating and pushing liquid specimens such as blood in cylindrical shape and removing it quantitatively, only the portion necessary for measurement may be selected and sampled.

    • An apparatus for analyzing liquid specimen comprising a sampling valve (11) consisting of two fixed elements (10), (14), and a movable element (12) held between these fixed elements, sample aspiration means (C0), diluent liquid dispensing means (Ci), and chamber (Bi) for receiving diluent liquid and sample, which further comprises measuring item setting means (30), control means (28) for selectively operating the dispensing means, and driving means (26) for driving each dispensing means according to its control signal. By composing in this manner, in the apparatus for analyzing liquid specimen for aspirating and pushing liquid specimen such as blood in cylindrical shape by means of a sampling valve, taking out quantitatively, treating as required, and analyzing, only a sample necessary for measurement is selected, and is diluted or otherwise treated.
    • 一种用于分析液体试样的装置,包括由两个固定元件(10),(14)和保持在这些固定元件之间的可移动元件(12)组成的取样阀(11),样品抽吸装置(C0),稀释液分配装置 (Ci)和用于接收稀释剂液体和样品的室(Bi),其还包括测量物品设定装置(30),用于选择性地操作分配装置的控制装置(28)和用于驱动每个分配装置 根据其控制信号。 通过这样构成,在利用取样阀对液体样品如血液进行抽取和推压的液体试样分析装置中,定量取出,根据需要进行处理,分析只需要测定的样品为 选择,并进行稀释或以其他方式处理。

    • Apparatus for reading an identification code from a blood sample container includes an elastic member (42) which engages the upper side (34) of the sample container. A rotary device rotates the elastic member bidirectionally. An up-and-down moving device moves the elastic member up and down. A rotating/up-and-down moving control device (56) controls the movement of the container. An identification code reader (19) reads the sample code from the container, and a reading controller (57) permits the identification code reader to read from the container as it rotates in either forward or reverse direction. The elastic member abuts the upper part of the sample container and rotates it. If the identification code reader cannot read the identification code when the container rotates in the forward direction, the elastic member rotates the sample container in the reverse direction for the identification code to be read again.
    • 用于从血液样本容器读取识别码的装置包括与样本容器的上侧(34)接合的弹性构件(42)。 旋转装置双向旋转弹性构件。 上下移动装置上下移动弹性件。 旋转/上下移动控制装置(56)控制容器的运动。 识别码阅读器(19)从容器读取样本代码,并且读取控制器(57)允许识别码阅读器在向前或相反方向旋转时从容器读取。 弹性构件邻接样品容器的上部并使其旋转。 如果识别码阅读器在容器沿向前方向旋转时不能读取识别码,则弹性构件反向旋转样品容器,以便再次读取识别码。
