[0020] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides a cervical sampling swab through improvement. The technical solution of the utility model is:

[0022] like Figs. 1-3 As shown, a cervical sampling swab includes a protective tube 1, a handheld rod 2 is provided inside the protective tube 1, a cotton sleeve 3 is fixedly connected to the handheld rod 2, a protective component 4 is provided between the protective tube 1 and the handheld rod 2, the protective component 4 includes a magnetic block 41, the magnetic block 41 is fixedly connected to the bottom end of the protective tube 1, a threaded groove 42 is provided on the magnetic block 41, the internal thread of the threaded groove 42 is connected to a screw 43, the screw 43 is fixedly connected to the handheld rod 2, a positioning component 5 is provided on the protective tube 1, the bottom end of the protective tube 1 is made of iron, so the magnetic block 41 can be sucked onto the bottom end of the protective tube 1, in order to ensure hygiene and safety, the surfaces of the magnetic block 41 and the protective tube 1 can be made of medical plastic material, and the iron part of the protective tube 1 and the magnet in the magnetic block 41 can be wrapped inside the plastic material.

[0023] Furthermore, the positioning assembly 5 includes a sliding sleeve 51 , which is slidably connected to the protective tube 1 , and the surface of the sliding sleeve 51 is spherical.

[0024] Furthermore, the positioning assembly 5 also includes a limiting ring 52, which is slidably connected to the sleeve 51. The limiting ring 52 is ring-shaped and can be fixed at the vaginal opening, thereby controlling the sliding of the protective tube 1 on the sleeve 51. Since the surface of the sleeve 51 is spherical, it can slide at multiple angles on the limiting ring 52. Therefore, when the protective tube 1 is inserted into the reproductive tract, it can also adjust the direction or stir it to facilitate sampling.

[0025] Furthermore, the positioning assembly 5 also includes a scale 53, which is arranged on the surface of the protective tube 1. The scale 53 can be used to observe the relative sliding distance between the protective tube 1 and the limiting ring 52, that is, the depth of the protective tube 1 inserted into the reproductive tract.

[0026] Furthermore, the magnetic block 41 is hemispherical and has a smooth surface to prevent the magnetic block 41 from causing damage to the reproductive tract mucosa when the magnetic block 41 moves.

[0027] Furthermore, the cotton sleeve 3 is ring-shaped, and is sleeved on the handheld rod 2 , and the cotton sleeve 3 is located at one end of the handheld rod 2 close to the screw 43 .

[0028] The specific working method is: when taking a swab sample, if the sampling location is near the female's cervical opening, the limiting ring 52 can be placed against the female's vaginal opening, and then the magnetic block 41 together with the protective tube 1 can be inserted into the female's vagina. According to the required sampling location and depth, the protective tube 1 is inserted into the female's vagina to a sufficient depth. During this process, the insertion depth of the protective tube 1 can be known by observing the scale 53. During the insertion of the protective tube 1, the magnetic block 41 and the protective tube 1 will separate the cotton sleeve 3 inside the protective tube 1 from the mucous membrane in the reproductive tract, preventing the cotton sleeve 3 from contacting the internal environment of the reproductive tract before reaching the cervix, thereby preventing the cotton sleeve 3 from being contaminated in advance.

[0029] When the protective tube 1 is inserted to a sufficient depth, that is, when the magnetic block 41 reaches the vicinity of the cervical opening, the handheld stick 2 can be held by hand and pushed forward to push the magnetic block 41 adsorbed on the protective tube 1 away from the protective tube 1. At the same time, the handheld stick 2 can be stirred to make the magnetic block 41 stir near the cervical opening, and the edge of the magnetic block 41 can be used to scrape the mucus near the cervical opening, thereby soaking the cotton cover 3 and making enough mucus adhere to the cotton cover 3, thereby completing the sampling. After the sampling is completed, the handheld stick 2 is pulled back to make the magnetic block 41 re-adsorbed on the end of the protective tube 1, and the protective tube 1 together with the magnetic block 41 can be pulled out of the reproductive tract. After pulling out, the magnetic block 41 can be fixed and the handheld stick 2 can be rotated so that the screw 43 rotates and disengages from the magnetic block 41. Then the handheld stick 2 and the cotton cover 3 can be taken out of the protective tube 1.

[0030] The technical means disclosed in the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
