At present, the collection of clinical fecal samples is completed by a collection tube, which is composed of a tube cover, a sampling rod and a processing tube. The tube cover is connected with the sampling rod, and the sample rod in the processing tube can be taken out for sampling by unscrewing the tube cover. After the sampling is finished, put it back into the processing tube to process the sample. The shortcoming of the feces collection tube is that the tube body is short and the sampling rod is short. This reduces the comfort when taking stool samples. If the length of the tube body and the sampling rod is increased, the detection cost is increased to a certain extent. At the same time, in the current stool sample collection and detection, the collection step and the detection step are separate. This requires the sampling tube and the detection card to be marked separately. When the sample volume is large, it is not easy to match the sampling tube and the detection card one by one, resulting in confusion testing result. In addition, the stool sample dripped from the sampling tube to the test card during the test. This process is exposed to the environment, which can easily cause the sample to pollute the environment and the operator, and also reduce the operator's comfort accordingly.
