Description

Technical Field

[0001] The invention relates to the technical field of gynecological sampling instruments, and in particular to a gynecological clinical leucorrhea sampling and testing device. Background Art

[0002] Leucorrhea is a mixture of mucus secreted by the vagina, Bartholin's glands, and cervical glands, which also contains bacteria, white blood cells, and epithelial cells inside the vagina and cervix. Women who undergo routine leucorrhea examinations need to have their doctor take samples. The doctor uses a sterilized scraper or a cotton swab soaked in saline to collect secretions from the vaginal opening, deep vagina, and posterior vaginal fornix.

[0003] After sampling, the doctor needs to prepare the collected leucorrhea into a saline smear and observe it. The doctor can also go to the laboratory to check the pH value, cleanliness, pathogen biology, exfoliated cytology, etc. The pH value of leucorrhea is 3.6-6, which is slightly acidic. There are no bacteria and white blood cells, and the cell morphology is normal. If there are abnormalities in the above aspects, it indicates that women may have lesions in the vagina or cervix.

[0004] Routine examination of leucorrhea is a relatively common examination in clinical practice. It can determine whether a woman has genital tract inflammation or infection, and can also assist in determining whether a woman has genital tract inflammation. In the sampling process, most samples are taken using a cotton swab or scraper after using a vaginal dilator. When taking samples with a cotton swab or scraper, the sampling technique is more challenging. Too much force will cause pain and discomfort to the patient, while too little force will result in too little sampling. Summary of the invention

[0047] The specific working process of the leucorrhea sampling and inspection device of the present invention is as follows:

[0048] After disinfecting the inner and outer surfaces of the right expansion arc plate 11 and the left expansion arc plate 19, apply medical human body lubricating grease on the outer surfaces of the right expansion arc plate 11 and the left expansion arc plate 19, screw the limit nut 16 to the frontmost position of the adjusting screw 15, and close the right expansion arc plate 11 and the left expansion arc plate 19. Insert the front end of the closed position of the right expansion arc plate 11 and the left expansion arc plate 19 into the patient's vagina, and after pinching the extension plate 17 and the pulling plate 12, slowly rotate the limit nut 16 to move it toward the rear end of the outer ring of the adjusting screw 15, so as to control the expansion amplitude of the right expansion arc plate 11 and the left expansion arc plate 19, and check the condition of the vaginal wall and the surface of the cervix by expanding the vaginal opening and using a vaginal endoscope.

[0049] After the observation and inspection is completed, the vaginal vault position is observed with the aid of a vaginal endoscope, and the front ports of the guide tube 21 and the bucket-shaped guide tube 22 are brought close to the area to be sampled. The servo motor 312 is controlled by a control button to operate, and the servo motor 312 drives the driving gear 311 to rotate rapidly. Since the gear ratio between the driving gear 311 and the driven gear 310 is 1:5, the driven gear 310 will drive the screw rod 35 to rotate rapidly, and allow the nut 37 to move backward on the outer thread of the screw rod 35, pulling the hollow movable tube 34 backward, and pulling the silicone piston 33 to move backward rapidly inside the mucus collection tube 32, so that negative pressure is generated inside the mucus collection tube 32 and transmitted to the bucket-shaped guide tube 22, so that the bucket-shaped guide tube 22 in contact with the vaginal mucus extracts the sample into the mucus collection tube 32 for storage.

[0050] Supplementary explanation about the leucorrhea sampling and testing device of the present invention:

[0051] Refer to the instruction manual Figure 1 As shown:

[0052] The side of the guide tube 21 that contacts the left expansion arc plate 19 can be made into a bevel opening, and the edge of the bevel opening can be chamfered. The bevel opening on the guide tube 21 is used to contact the inner wall of the vagina, so that the negative pressure generated by the suction sampler 3 can directly act on the inner wall of the vagina, allowing the vaginal mucus attached to the inner wall to be quickly and effectively adsorbed into the mucus collection tube 32.
