Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a cervical cell sampling device that can independently collect cervical exfoliated cells under the guidance of a doctor or after an individual reads the instructions. Background technique

[0002] Cervical cancer is caused by the infection of cervical epithelial cells by human papillomavirus HPV, especially the persistent infection of high-risk HPV. According to literature reports, more than 97% of female cervical cancers are caused by HPV infection. HPV infection leads to abnormal growth of cervical epithelial cells, especially the epidermal cells in the cervical canal and cervical os. If persistent infection is not detected and treated in time, it will develop into cervical exfoliated cell lesions, and after several years of infection, it will develop into malignant cervical cancer. Therefore, collecting cervical exfoliated cells for cytological detection and HPV-DNA detection ha...
