The inspection principle and the using method of the embodiment are as follows:

firstly, vertically placing the whole device on a horizontal plane, taking out a sampling device part from a carrier, and firmly combining a screw cap, a spring, a fixed ring and a sampler together to form the sampling device; the screw cap of the sampling device is pinched by fingers, the threaded end at the front end of the excrement sampling device is gently inserted into five different places of excrement, the screw thread is just buried by paying attention to the insertion depth, and the sampling device cannot be inserted too deeply or too shallowly. After excrement and urine sampling, insert the solid fixed ring of above-mentioned sampling device oral area on the carrier to fixed, sealed through the first sealing washer of first funnel mouth department this moment, during sample thief front end screw thread department submerges the sample diluent this moment, pick up whole detection device, control and fully rock 10 times, let the diluent fully vibrate, make the collection on the sampling rod screw thread excrement and urine fully dissolve in the diluent. Then the screw cap is unscrewed to expose the tail part of the sampler wound by the spring, and the tail part pressing part of the excrement sampler is pressed down by thumb until the pressing part is not pressed. In the pressing process, the front end of the excrement sampling device descends, the rubber plug at the second hopper opening is pushed open firstly, so that diluent in the carrier begins to flow downwards, after a certain amount of liquid flows downwards, the second sealing ring continues to descend along with the excrement sampling device, and when the second sealing ring reaches the hopper opening at the lower end, sealing is achieved, so that more liquid is prevented from flowing downwards. And part of the liquid flowing down stays in a cuboid sample cell of the lower cover plate, at the moment, a sample buffer solution permeates from the bottom end of the detection reagent strip to the upper end under the capillary action and the capillary action, and a target substance (human hemoglobin) in the buffer solution is combined with the colloidal gold-labeled mouse anti-human hemoglobin antibody and is captured by the capture antibody on the NC membrane and the quality control line antibody, so that the whole detection process is completed. If the position of the T line and the C line on the detection reagent strip have color reaction, the reaction is positive; if only C line is colored and T line position is colorless, then it is negative; if the C line position also has no color reaction, no matter whether the T line has reaction, the detection is invalid.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
