Background

Human Papillomaviruses (HPV) are a genus of papillomavirus A belonging to the family of papovaviridae, and are spherical DNA viruses that cause squamous epithelial proliferation of the human skin mucosa, and over 130 have been isolated.

When HPV detection is carried out on a human body, human body cells need to be collected and collected into a sampling tube, then the sampling tube is placed on a vortex mixer to be oscillated, and then liquid uniformly mixed in the sampling tube is guided into a detection tube for detection on a computer to carry out detection on the computer.

In order to avoid transferring larger tissues, mucus and other impurities of the human body into a detection tube used for loading, so that the instrument is blocked by sample suction during loading. Therefore, a filter screen is required to be arranged inside the sampling tube to filter out larger tissue mucus and impurities.

Because the sampling tube used in the hospital is separated from the detection tube used on the computer at present, the liquid in the sampling tube needs to be moved to the detection tube used on the computer by an experimenter before the computer is operated, the time consumed in the process is about 1.5 hours, the hydraulic transfer process is easy to make mistakes, and the liquid is easy to be polluted.
