    • The present invention relates to a cup handling subsystem for an automated clinical chemistry analyzer system which includes a nestable sample cup for holding sample mixtures, a cup dispenser mechanism for holding and dispensing a supply of the cups into a sample shuttle for transporting them, and an incubator for controlling the temperature of the cup and its contents. In one embodiment, the cups include a conical lower portion and a cylindrical upper portion having a top flange, a bottom flange and a groove formed therebetween. An apparatus is provided for holding and dispensing a plurality of such cups including a supply tube for holding the cups in a stack wherein the stack has a bottom-most cup and a next-bottom-most cup located above the bottom-most cup. The apparatus also includes an escapement located at a lower end of the supply tube which includes a disk having an aperture formed therein, a first leaf attached to a top side of the disk and a second leaf attached to a bottom side of the disk. The disk is movable between a first position in which the second leaf engages the bottom flange of the bottom-most cup and a second position in which the first leaf is inserted into the groove of the next-bottom-most cup and engages the top flange of the next-bottom-most cup and in which the second leaf no longer engages the bottom flange of the bottom-most cup. In the second position, the bottom-most cup is free to fall through the aperture formed in the disk.
    • 本发明涉及一种用于自动临床化学分析仪系统的杯子处理子系统,其包括用于保持样品混合物的可嵌套样品杯,用于保持和分配杯子供应到用于运输它们的样品梭中的杯分配器机构,以及 用于控制杯子及其内容物的温度的培养箱。 在一个实施例中,杯包括锥形下部和具有顶部凸缘,底部凸缘和在其间形成的凹槽的圆柱形上部。 提供了一种用于保持和分配多个这样的杯子的装置,其包括用于将杯子保持在堆叠中的供给管,其中所述烟囱具有最底部的杯子和位于最下面的杯子上方的下一个最下面的杯子。 该装置还包括位于供应管的下端处的擒纵机构,其包括具有形成在其中的孔的盘,附接到盘的顶侧的第一叶片和附接到盘的底侧的第二叶片。 盘可以在其中第二叶片接合最底部杯的底部凸缘的第一位置和第二位置之间移动,第二位置中第一叶片插入下一个最下面的杯子的凹槽中并且接合顶部凸缘 的下一个最下面的杯子,其中第二个叶子不再接合最底部的杯子的底部凸缘。 在第二位置,最下面的杯子可自由地落入通过形成在盘中的孔。

    • Disclosed is an improved electrochemical sensor having a base bearing a working and counter electrode which provides a flow path for a fluid test sample. The working electrode has a reaction layer on its surface which contains an enzyme capable of reacting with an analyte to produce electrons which are received by the working electrode. The base is mated with a cover to form a capillary space into which the test fluid is drawn. The improvement involves configuring the working and counter electrodes so that a major portion of the counter electrode is located downstream on the flow path from the working electrode with the exception of a small sub-element of the counter electrode which is in electrical communication with the primary portion of the counter electrode and located upstream of the working electrode. This configuration provides the sensor with the capability of sending a greatly reduced electrical signal to the device's detecting element in the event that the capillary space is incompletely filled with test fluid. This reduced signal can be manipulated to produce an error signal which affirmatively apprises the device's user that such incomplete filling has occurred.
    • 公开了一种改进的电化学传感器,其具有承载工作和反电极的基座,其提供用于流体测试样品的流动路径。 工作电极在其表面上具有含有能够与分析物反应以产生由工作电极接收的电子的酶的反应层。 基座与盖子配合以形成毛细管空间,测试流体被拉入其中。 改进之处在于配置工作电极和对电极,使得对电极的主要部分位于来自工作电极的流动路径的下游,除了与电极电连接的对电极的小子元件之外 并且位于工作电极的上游。 这种配置使得传感器能够在毛细管空间不完全填充测试流体的情况下将大大减小的电信号发送到装置的检测元件。 该减小的信号可以被操纵以产生一个误差信号,该误差信号肯定地认识到设备的用户已经发生了这样的不完全填充。
