As shown in figure 1, the rapid sample adding detection device comprises a detection plate 1, a sample adding insertion sheet 2 and a sheath 3. A test paper placing groove 1-1 is formed in one side face of the detection plate 1. The bottom end of the test paper placing groove 1-1 is communicated with the bottom end face of the detection plate 1. A reagent strip is arranged in the test paper placing groove 1-1. The bottom end of the reagent strip extends out of the test paper accommodating groove 1-1.
As shown in FIGS. 1 and 2, the sample-adding insertion piece 2 is composed of a connection piece 2-1 and a capillary sheath 2-2. The capillary sleeve 2-2 is fixed with the inner side surface of the connecting sheet 2-1. The length of the connecting sheet 2-1 is greater than that of the capillary sleeve 2-2; the bottom end of the connecting sheet 2-1 is flush with the bottom end of the capillary sleeve 2-2. The inner side surface of the connecting sheet 2-1 is connected with the side surface of one side of the detection plate 1. The inner cavity of the capillary sleeve 2-2 is butted with the test paper placing groove 1-1 on the detection plate 1. The cross section of the inner cavity of the capillary sleeve 2-2 is rectangular. The reagent strip extends into the inner cavity of the capillary sleeve 2-2. The difference between the thickness of the inner cavity of the capillary sleeve 2-2 and the thickness of the reagent strip is equal to 2mm, so that the distance between the two side surfaces of the reagent strip and the two side walls of the inner cavity of the capillary sleeve 2-2 is 1mm, and a capillary seam is formed. When the capillary sleeve 2-2 is immersed in the liquid, the liquid quickly rises along the gap between the reagent strip and the capillary sleeve 2-2 under the action of capillary phenomenon.
The detection plate 1 is adhered with a self-adhesive label. The adhesive label covers the test paper placing groove 1-1 and sticks the connecting sheet 2-1 on the sample adding inserting sheet 2.
