Technical Field

[0001] The utility model relates to the technical field of sampling brushes for HPV detection, in particular to a sampling brush for HPV detection. Background Art

[0002] When conducting an HPV test, doctors will use a sampling brush to gently scrape cell samples from the vaginal wall of female patients for HPV testing. However, the existing sampling brushes for HPV testing still have certain defects when used, such as;

[0003] For example, an HPV sampling stick with publication number CN217244498U, when in use, the brush head and the cover are connected to the cervix, and the end of the cover remains outside the body. The stick body is pushed to make the brush head pass through the cover. After the brush head is rotated for sampling, the stick body is pulled to make the brush head return to the cover to save the sampling liquid and cells, and then the cover is taken out. Since the outside of the cover is smooth, the discomfort is greatly reduced, and it is convenient and quick to use.

[0004] However, the HPV sampling stick still has the following disadvantages in actual use:

[0005] The brush head needs to be connected with the cover to enter the cervix, so the tester will feel uncomfortable when taking samples, and when the brush head is extended outside the cover, the depth and direction of the brush head may not be accurately controlled, resulting in insufficient or inaccurate sampling, and when the brush head rotates, the cover may be affected, causing the cover to rotate inside the body, resulting in overall inconvenience in operation and possible damage to the tissue structure of the inner wall of the cervix.

[0006] In view of the above problems, it is urgently necessary to carry out innovative design based on the original sampling brush for HPV testing. Therefore, we proposed a sampling brush for HPV testing that can well solve the above problems. Utility Model Content
