Description

Technical Field

[0001] The utility model relates to a female vaginal sample autologous collector, belonging to the technical field of sample collectors. Background Art

[0002] Cervical cancer is the main killer of women's health and life. The original intention of this study is to develop safe, convenient, disposable sterile female vaginal self-sampling swabs that meet the requirements of medical examinations, protect women's privacy, and improve the detection rate of cervical cancer pathogenic viruses in my country.

[0003] After searching, a Chinese patent with announcement number CN208769838U discloses a cervical sample collector, the technical highlights of which are: it includes a swab head and a sampling rod, the swab head is fixed at the end of the sampling rod, the sampling rod is provided with a breaking point near the swab head, the collector also includes an outer sleeve, the outer sleeve is movably mounted on the sampling rod, the inner diameter of the outer sleeve is smaller than the radial width of the swab head; preferably, the length of the outer sleeve is less than or equal to the length of the sampling rod.

[0004] In the above scheme, an outer sleeve is put on the sampling rod. When sampling, the outer sleeve is put on the breaking point on the sampling rod to prevent the sampling rod from breaking at the breaking point, thereby preventing the swab head from falling into the vagina. However, the swab head needs to be manually broken after sampling, which increases the risk of sample contamination and has low efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
