Abstract
A sample loading bottom plate (300,600, 810, 820, 831) and an immunochromatography detection apparatus (10) containing the sample loading bottom plate (300, 600, 810, 820, 831). During design of the sample loading bottom plate (300, 600, 810, 820, 831), a sample loading portion (310, 833) having a multistage-step structure is additionally provided on a sample loading region and comprises multistage steps having different heights, wherein a base surface (311) is used for carrying a sample solution. After a cover plate (100, 500, 834) is covered, the sample solution falls on the base surface (311) and then flows upwardly, and by means of the flow-intercepting and buffering effects of the multistage-step structure, the sample solution which finally flows to a top surface (342, 642) of the highest step (340, 640) can basically flow to sample loading regions of immunochromatography detection members synchronously, so that the multiple immunochromatography detection members can basically receive the sample solution synchronously, the unifying problem of time and sample horizontal lines is solved, and the test accuracy is high; moreover, only one-time sample adding is needed, the detectio…
