[0002] Stool testing can be used to assist in the diagnosis of a variety of diseases. For example, gastrointestinal bleeding can be caused by a variety of diseases. By testing hemoglobin or transferrin in the stool, it can be used to check whether the subject has gastrointestinal bleeding.

[0003] During the feces sampling process, it will contain many large particles of dietary fiber, food residues, etc., which will affect the efficiency of the extraction of the test substances and increase the difficulty of the testers' work. Therefore, the feces need to be diluted. The dilution process is to add the feces to water and stir it continuously, and finally filter the residue and extract the diluted feces liquid, which is time-consuming and labor-intensive.

[0004] As for stool samples, they are usually collected by the patients themselves and placed in a specified stool collection tube, which is then handed over to the relevant personnel for testing. Currently, the sampling of stool samples basically relies on manual operation by the patients themselves, which is not only inconvenient, but also often causes sampling difficulties due to the patients' unfamiliarity with the operation, or causes the samples to be contaminated and affect the test results.

[0005] Therefore, it is necessary to propose a stool sampling valve and a healthy toilet to dilute and sample the stool after the patient has defecation, so as to improve the efficiency of stool sampling. Utility Model Content

The front end of the main body 1 is close to the toilet bowl. The main body 1 has a columnar structure, and its rear end is fixedly connected to the water pipe 3 through a threaded connection, so that the bottom flushing channel 11 is connected to the water pipe 3.

[0028] In this embodiment, the ventilation sampling and cleaning integrated part 12 is arranged in parallel with the bottom flushing channel 11. The ventilation sampling and cleaning integrated part 12 has a blowing function, a negative pressure sampling function, and a backwashing function connected to the toilet water supply. The rear end of the ventilation sampling and cleaning integrated part 12 is connected to the vacuum pump and the blowing pump, and a switching valve is provided between them for switching between blowing and absorbing water. When the toilet is in normal use, the position of the water cover is kept at a certain height. After the patient has finished defecating, the feces is soaked in the position below the water cover, and then the ventilation sampling and cleaning integrated part 12 is cleaned. 2. Blow air into the water to stir the feces in the form of turbulent airflow in the water, so that the feces are loosened. After the feces are fully stirred, the ventilation sampling and cleaning integrated part 12 absorbs a preset amount of feces, and the absorbed feces will be stored in a storage tank or storage bottle. After the absorption is completed, the feces sampling is completed, which is convenient and fast. After the sampling is completed, the ventilation sampling and cleaning integrated part 12 can be backflushed and cleaned, that is, the ventilation sampling and cleaning integrated part 12 is cleaned by reversely delivering the cleaning liquid, and finally the bottom flushing channel 11 is flushed with water to flush away the feces.
