[0028] Referring to Figure 3 , a pull ring 8 is fixedly connected to the bottom of the push-pull rod 6, and the pull ring 8 is used in cooperation with the push-pull rod 6.

[0029] As a technical optimization scheme of the present invention, by setting the pull ring 8, it is convenient for the user to push, pull or rotate the push plate 3, enhancing the comfort of the user.

[0030] Referring to Figure 3 , a limit sleeve 9 is arranged at the bottom of the collection bucket 1, and the top of the limit sleeve 9 extends into the collection bucket 1 and is slidably connected with the inner wall of the collection bucket 1.

[0031] As a technical optimization scheme of the present invention, by setting the limit sleeve 9, the push plate 3 can be limited to prevent the push plate 3 from detaching from the limit groove 2.

[0032] Reference Figure 3 On both sides of the inner wall of the limit sleeve 9, through grooves 10 are provided, and the through grooves 10 are used in cooperation with the pull ring 8.

[0033] As a technical optimization scheme of the utility model, by arranging the through grooves 10, it is convenient for the user to install the limit sleeve 9, and prevent the phenomenon that the inner diameter of the limit sleeve 9 is too small to quickly pass through the pull ring 8.

[0034] Reference Figure 3 A friction ring 11 is sleeved on the surface of the push plate 3, and the surface of the friction ring 11 contacts the inner wall of the limit groove 2.

[0035] As a technical optimization scheme of the utility model, by arranging the friction ring 11, the push plate 3 can be made to contact the inner wall of the limit groove 2 more closely, and the contact area between the push plate 3 and the limit groove 2 is increased.

[0036] Reference Figure 3 A plurality of collection grooves 12 are provided on the surface of the cotton sleeve 5, and the collection grooves 12 are used in cooperation with the cotton sleeve 5.

[0037] As a technical optimization scheme of the utility model, by arranging the collection grooves 12, the endometrial cells shed by the cotton sleeve 5 rubbing against the inner wall of the vagina can be collected, and the phenomenon that the endometrial cells are rubbed and dropped when the cotton sleeve 5 is retracted into the collection barrel 1 is avoided.

[0038] Reference Figure 3 A plurality of strengthening blocks 13 are fixedly connected to the bottom of the push plate 3, and the inner sides of the strengthening blocks 13 are fixedly connected to the surface of the push-pull rod 6.

[0039] As a technical optimization scheme of the utility model, by arranging the strengthening blocks 13, the push-pull rod 6 can be strengthened, and the phenomenon of easy fracture during use is avoided.

[0040] Working principle and usage process of the present utility model: When in use, first rotate the protective sleeve 71. The protective sleeve 71 drives the slider 72 to slide inside the L-shaped chute 73. After rotating to the extreme position, pull the protective sleeve 71 upward. The protective sleeve 71 drives the slider 72 to move upward, so that the protective sleeve 71 moves away from the collection barrel 1. After moving away, insert the front end of the collection barrel 1 into the vagina of the subject to be collected. After inserting two-thirds, push the push rod 6 forward through the pull ring 8. The push rod 6 drives the push plate 3 to move forward. The push plate 3 drives the connecting rod 4 and the cotton sleeve 5 to move forward, so that the front end of the cotton sleeve 5 moves outside the collection barrel 1 and contacts the inner wall of the vagina. After contact, rotate the push rod 6 and the push plate 3 through the pull ring 8. The push plate 3 drives the connecting rod 4 and the cotton sleeve 5 to rotate, so that the cotton sleeve 5 rubs against the inner wall of the vagina to collect menstrual blood endometrial cells. After collection, pull back the push rod 6. The push rod 6 drives the push plate 3, the connecting rod 4 and the cotton sleeve 5 back into the collection barrel 1. Then take out the collection barrel 1. After taking out, wipe the surface of the collection barrel 1. After wiping, reinstall the protective sleeve 71 to play a protective role. Finally, when it is necessary to extract the sample, remove the limit sleeve 9. After removal, pull the pull ring 8 backward to take out the cotton sleeve 5 for collection.

[0041] In summary, for the menstrual blood endometrial cell collection device, by rotating the protective sleeve 71, the protective sleeve 71 drives the slider 72 to slide inside the L-shaped chute 73. After rotating to the extreme position, pull the protective sleeve 71 upward. The protective sleeve 71 drives the slider 72 to move upward, so that the protective sleeve 71 moves away from the collection barrel 1. After moving away, insert the front end of the collection barrel 1 into the vagina of the subject to be collected. After inserting two-thirds, push the push rod 6 forward through the pull ring 8. The push rod 6 drives the push plate 3 to move forward. The push plate 3 drives the connecting rod 4 and the cotton sleeve 5 to move forward, so that the front end of the cotton sleeve 5 moves outside the collection barrel 1 and contacts the inner wall of the vagina. After contact, rotate the push rod 6 and the push plate 3 through the pull ring 8. The push plate 3 drives the connecting rod 4 and the cotton sleeve 5 to rotate, so that the cotton sleeve 5 rubs against the inner wall of the vagina to collect menstrual blood endometrial cells. After collection, pull back the push rod 6. The push rod 6 drives the push plate 3, the connecting rod 4 and the cotton sleeve 5 back into the collection barrel 1. Then take out the collection barrel 1. After taking out, wipe the surface of the collection barrel 1. After wiping, reinstall the protective sleeve 71 to play a protective role. Finally, when it is necessary to extract the sample, remove the limit sleeve 9. After removal, pull the pull ring 8 backward to take out the cotton sleeve 5 for collection. Thus, it has the advantage of being convenient for collection, and solves the problem that most existing collection devices collect menstrual blood by inserting a cotton swab into the vagina and scraping the inner wall of the vagina. However, because the cotton swab is small in volume, the operator needs to exert force to scrape the inner wall of the vagina, which may cause the subject to feel pain or be injured, reducing the practicality of the collection device.
