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 a major killer of women's health and life. In 2020, there were about 110,000 new cases of cervical cancer in my country, and about 60,000 deaths. We call on women to undergo accurate screening. At present, the screening rate in my country is less than 30%, far lower than 80% in Europe and the United States. The accuracy rate of vaginal self-sampling detection is as high as 99%, which has been recognized by Chinese experts. The original intention of this study is to study safe and convenient disposable sterile female vaginal self-sampling swabs that meet the requirements of medical examinations, protect women's privacy, and increase 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.

[0032] Specifically, a first positioning ring groove 16 is formed at the rear end of the inner wall of the second cylinder 8 , and a first clamping ring 17 rotatably connected to the first positioning ring groove 16 is fixedly connected to the front end of the outer wall of the driving ring 13 .

[0033] The driving ring 13 is provided with a track groove 18 extending in the vertical direction, the rear end of the push rod 2 extends into the driving ring 13, and the rear end of the push rod 2 is fixedly connected with a driving column 19 that passes through the track groove 18 and extends into the thread groove 11. The middle part of the thread groove 11 is provided with a plurality of limiting edges 20 extending along the length direction of the main body 1. When the driving column 19 is clamped between the limiting edges 20, the sampling head 3 extends out of the main body 1 and the breaking groove 6 is located inside the main body 1.

[0034] A first limiting groove 21 is opened on one side of the tail end of the track groove 18, and a second limiting groove 22 is opened on the other side of the track groove 18 near the front end. When the driving column 19 is located in the first limiting groove 21, the sampling head 3 is located inside the main body 1.
