When women treat vaginitis, they usually use vaginal medication, which is mostly done by intravaginal insertion of medication. Usually when vaginal medication is placed, it needs to be placed in the posterior vaginal fornix, the circular cavity between the cervix and the vaginal wall, so as to avoid expelling the medication while standing and to improve the absorption of the medication. The posterior wall of the vagina is 10-12 cm long and the vaginal fornix is the deepest. If it cannot be plugged in any more, it means that the medicine has reached the fornix. 1. Wash your hands before giving the medicine; 2. Pull out the piston of the medicine injector as far as possible and put the medicine into the injector; 3. Lie on your back with your knees bent; 4. Gently insert the injector deep into the vagina and press down the piston to push the pill into the vagina; 5. Pull out the piston from the injector after use and wash it with warm water and soap to keep it clean. 1. Pay attention to the time of vaginal plugs: vaginal plugs should be administered at night so that the medication can be fully decomposed during sleep and act directly on the local area; 2. Pay attention to cleanliness: during the medication period, keep the vulva as clean and dry as possible, wear cotton breathable underwear and change them daily; 3. : improve the resistance of the whole body.
