[0003] The existing authorized patent announcement number is: CN106680477B. The utility model is an integrated device for feces sampling and occult blood detection. When sampling, remove the cover, use the free head end of the feces collection stick to collect feces, let the feces stain the threaded part of the feces collection stick, insert the feces collection stick back into the circular tube cavity, shake the device to make the feces fully dissolved in the solution, remove the limit block, press the cover to the bottom, then push the piston down through the feces collection stick, so that the tip of the piston rod pierces the sealing piece, so that the quantitative mixed solution in the piston groove enters the receiving groove of the base, and the mixed solution flows into the groove of the base through the slope. The bottom of the groove just contacts the glass fiber end at the bottom of the test strip. The mixed solution starts to run on the plate through the glass fiber siphon effect of the test strip, and a color band appears. Wait for 10 minutes to check the quality control line and the detection line color of the test strip observation window, compare the color card, and determine the result.

[0004] Currently, there is only one test strip in the existing technology. A stool sample can only be tested for one test after multiple steps. To detect other pathogens, the corresponding test strip needs to be replaced. It is currently inconvenient to replace the test strip and cannot detect multiple pathogens at the same time.
