The conventional closed collection method is that a patient adopts a common open cup to sample excrement by himself. The collection mode is easy to cause pollution to the environment in use; if pathogens exist in the excrement of the person to be tested, the medical staff are easily injured. In addition, the collection mode is inconvenient to operate, and ordinary personnel cannot collect enough and uniform samples by themselves. In addition, when the sample is extracted, the operation is complicated, and the rapid sampling and detection are inconvenient.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a stool sampler [200520063737.4], which comprises a bottle body, a bottle cap correspondingly screwed on the top of the bottle body, a drip nozzle installed on the bottle cap, a drip nozzle cover equipped on the drip nozzle, a stool residue filter screen installed in the bottle cap corresponding to the through hole of the drip nozzle, a fork-shaped sampling spoon installed on the main body of the drip nozzle in the bottle cap, the sampling spoon extending into the bottle body at its front end, and a specimen preservative solution contained in the bottle body.
