[0002] When collecting human saliva, nasal discharge and the like in medical detection, sampling is carried out through a cotton swab, and then the collected sample is placed in a solution in a sample storage tube for storage. In order to facilitate the capping operation of the sample storage tube cap, the cotton swab also needs to be broken. This method first separates the cotton swab and the sample storage tube for packaging. In actual application, the cotton swab may be discarded or dropped, and after sampling, the cotton swab needs to be broken, thereby increasing the risk of contamination of the sample storage solution. When the sample is taken out, the storage solution needs to be poured out or extracted through an extraction tube.
