    摘要： A reflection plate for a biochemical measuring instrument which is adapted to evaluate a biochemical value by obtaining a reflective property of a reflection surface of the reference reflection plate, obtaining a reflective property of test paper impregnated with biochemical sample and mounted on a test stick, and comparing the two reflective properties, wherein: the reflection surface of the reference reflection plate is depressed from the periphery thereof. Thereby, even though the test stick is required to be placed adjacent to the reflection surface to achieve a uniformity the optical arrangement in obtaining the two reflective properties, the contamination of the reflection surface from the sample can be prevented. Preferably, the reference reflection plate itself may be provided with a depression to defined the reflection surface at the bottom of this depression.

    摘要： A test strip adapted to receive a sample and detect an analyte therein is provided. The test strip comprises a sample addition zone to which a sample may be added; an absorbent zone proximal to the sample addition zone; one or more test zones distal to the sample addition zone, at least one of the test zones including a first analyte binding agent immobilized therein which is capable of binding to the analyte to be detected; and a terminal sample flow zone distal to the one or more test zones, the absorbent zone being positioned relative to the sample addition zone and having an absorption capacity relative to the other zones of the test strip such that a distal diffusion front of a sample added to the sample addition zone diffuses from the sample addition zone to a distal diffusion point within the terminal sample flow zone and then reverses direction and diffuses proximal relative to the one or more test zones.

    摘要： A test sample color comparison device is disclosed which has a casing unit with an insertion slot for inserting a color test sample therein, and a display section for displaying the color test sample adjacent at least one of a plurality of reference color shades, as the reference color shades are successively moved into position adjacent the color test sample by a manipulation wheel. When an operator determines that a reference color shade adjacent the test sample corresponds in color to the color of the test sample, he pushes a switch to cause a readout of stored information corresponding to the reference color shade then adjacent the test sample. Readout of the stored information is based on a bit pattern set by a plurality of converter switches which are turned on and off in different patterns which correspond to the different color shades as the reference color shades are moved into position by the manipulation wheel. An uneven pattern code section moves in association with the manipulatable wheel and actuates the converter switches. A preferred uneven pattern code section is arranged so that all of the converter switches are actuated roughly equally during a full rotation of the manipulatable wheel, and so that only one of the converter switches is switched on or off during incremental movement of the manipulable wheel.
