[0002] By testing the intestinal microecology, we can understand the health status of the human body, predict the risk of disease, provide effective guidance for disease treatment, and make the treatment of disease more targeted. . The detection of microorganisms in fecal samples has special significance for the health of human intestinal microecology. Feces is the source of intestinal microbial nucleic acid. In order to improve the accuracy of intestinal gene testing, fecal sample collection usually requires the use of a collection device. Some existing stool sample collection devices are inconvenient to use, cannot achieve quantitative collection of stool samples and are therefore not suitable for quantitative testing, and are inconvenient to store and transport the collected stool samples. Some other conventional stool sample samplers have the following defects and cannot meet the needs of clinical applications: (1) The handheld part of the traditional sampler is relatively short, which makes sampling inconvenient and easy to dirty hands; (2) Traditional samplers mostly use a small spoon structure to take samples, and multiple repeated collections are required to reach the required amount of stool for sampling. The operation process is complicated and easily causes psychological pressure on users; (3) The feces collected by the traditional sampler is not easy to separate and cannot fully react with the lysis solution, which is not conducive to subsequent testing; (4) Most traditional samplers are made of cheap transparent plastic, which is easy to break under stress and easily causes psychological pressure on users when used; (5) Traditional sampling is arbitrary and the collection amount cannot be guaranteed, resulting in too much or too little.
