[0072] (chromatographic measuring equipment)

[0073] First, the arrangement of the chromatography measurement apparatus 1 according to the first embodiment is described. figure 1 is a schematic perspective view illustrating the appearance of the chromatography measuring apparatus 1 of this embodiment, and, figure 2 is along figure 1 A schematic diagram of the interior of the chromatographic measurement device 1 , in which the immunochromatographic device 20 is loaded, is shown in a cross section taken by line I-I. Figure 3A with Figure 3B is a schematic plan view and a schematic bottom view illustrating the appearance of the device 20, and, Figure 3C is shown along the Figure 3A A schematic cross-sectional view taken on line II-II.

[0074] Such as figure 1 with 2As shown in , the chromatographic measurement device 1 includes: a housing 10; a screen display unit 11 arranged on the surface of the housing 10; a menu operation part 12 for operating the menu displayed...

[0164] Figure 7 is a schematic sectional view illustrating a measuring device 2 according to a second embodiment of the present invention. The difference between the measuring device 2 and the measuring device of the first embodiment is that the information obtained by the image sensor(s) of the first measuring unit 40 and / or the second measuring unit 50 is displayed on the screen in real time. unit 11, and can store information in the form of images. Other points are the same as those of the first embodiment, and therefore will not be described in detail unless otherwise required.

[0165] In addition to the components of the measuring device 1, the measuring device 12 includes: a storage unit 36 ​​for storing information received from the measuring units 40 and 50; an image forming unit 37 for forming an image based on the above information; and an image processing unit 38 for applying image processing to the image formed by the image forming unit 37.

Abstract

A chromatographic measurement apparatus (1) for measuring a color development state of an insoluble carrier (21) with a sample solution and a label solution developed thereon to test a test article, the insoluble carrier (21) including a test detection area (A, B) where a material that binds specifically to a test article is immobilized and a control detection area (C) used for determining an end of measurement. The chromatographic measurement apparatus (1) includes : a determining unit (32) for carrying out determination of validity and determination of necessity of amplification of a test result of the test article; and an amplifying unit (60) for amplifying the color development state according to the result of the determination of necessity of amplification by the determining unit (32) . The amplification is carried out only when it is determined that amplification is necessary.

Description

technical field [0001] The present invention relates to a chromatographic measuring device that uses chromatographic methods to perform measurements of analytical devices. Specifically, the present invention relates to a chromatographic measurement device for testing a test article by measuring the color development state of a test line and a control line in which a material specifically binding to the test article is immobilized, and the control line is used to determine the end of the measurement. Background technique [0002] In recent years, many analytical devices have been developed for testing test articles in a simple and rapid manner using analytical methods such as immunoassays in which a sample (sample solution) possibly containing a test article is fed onto the carrier. Various analytical devices for testing in vitro diagnostic agents, toxic substances, etc. are now commercially available. An example of such a device is an example disclosed in Japanese Unexami...
