Cervical/vaginal cast-off cell self-harvesting device

Abstract

The invention discloses a cervical / vaginal cast-off cell self-harvesting device. The device comprises a sample bottle and a sampler. The sample bottle comprises a bottle cap, a bottle body and solid-state filter paper. A cone part is arranged on the inner lower portion of the bottle body, and the solid-state filter paper is matched with the cone part in appearance and attached to the cone part in a lining mode. After the sampler harvests cervical / vaginal cast-off cells, the sampler is placed inside the sample bottle, the head portion of the sampler is placed inside the cone part, and the head portion of the sampler makes tight contact with the periphery of the solid-state filter paper. By means of the cervical / vaginal cast-off cell self-harvesting device, the DNA / RNA of the harvested cells can be reserved to the maximum degree, hence, HPV detection sensibility is greatly improved, and the screening mode that 'cervical / vaginal cell self-sampling high-risk HPV detection is turned into cervical cancer preliminary screening' can be improved; in addition, the cervical / vaginal cast-off cell self-harvesting device can also be used for storing the DNA / RNA of the cells at an indoor temperature, the self-harvesting device is small in size and can be sent, and thus central detection is facilitated.

Description

technical field [0001] The invention relates to a device for self-collecting exfoliated cells of the human body, in particular to a device for self-collecting and preserving exfoliated cells of the cervix and vagina. Background technique [0002] Endometrial cervical cancer is caused by human papillomavirus (Human PapillomaVirus, HPV). It is the only cancer with a clear etiology, which seriously threatens women's lives. Large-scale population screening is the most important preventive measure. The high cost of screening and insufficient medical resources have seriously restricted the screening of the entire population. Especially in poor areas where medical resources are scarce, the contradictions are more prominent and need to be resolved urgently. We have explored new technologies for cervical cancer screening and established a program of "preliminary screening of cervical cancer by detection of high-risk HPV in self-collected cervical and vaginal cells". This new screeni...

Problems solved by technology

However, the existing method is to simply apply the sampler to the solid filter paper and then discard the sampler, so that only a small amount of cells can be transferred to the filter paper, and 90% of the cells are discarded with the sampler, plus the cells obtained by the cervical vaginal self-sampling technology The number is small, which greatly reduces the sensitivity of self-collected specimens to detect HPV
