HPV is a common sexually transmitted infectious virus that is closely related to the occurrence of various cancers, including cervical cancer, anal cancer, oropharyngeal cancer, etc. In particular, the risk of anal HPV infection significantly increases in immunocompromised populations, such as HIV-infected individuals. This infection not only affects the quality of life of patients but also can lead to serious health consequences.

[0003] Although the incidence of anal HPV infection is high, due to insufficient social awareness and limitations of detection methods, many infected individuals fail to receive timely diagnosis and treatment. Traditional methods of anal HPV detection usually require professional medical personnel to use anal swabs to sample exfoliative cells from the anus and place them in a sampling tube for preservation to facilitate subsequent detection. Patients themselves are difficult to operate independently, which not only increases the burden on medical resources but also may lead to patients' reluctance to accept detection due to privacy concerns. Moreover, the anal swab in reality may cause an unsmooth collection process, causing discomfort to patients. In addition, the sampling tube cap and sampling tube are usually connected by threads, and the sampling tube cap may become loose and cause sample leakage when used for a long time or subjected to external impact.
