How is the contraceptive ring used for contraception? You should know these basic knowledge

Contraceptive ring, also called contraceptive ring, is a contraceptive device placed in uterine cavity, because the first device used is usually called pregnancy test ring. The intrauterine device has little interference to the whole body and does not affect the safety, effectiveness, reversibility and convenience of delivery. In China, the contraceptive rate of IUD is over 40%.

Introduction.

Use method 1.

Using a vaginal contraceptive ring is very simple. On the fifth day of menstruation, medical staff put it in the deepest part of the vagina (behind the vagina).

The front and back walls of the vagina are usually closed, so the vaginal contraceptive ring is usually not easy to take out from the vagina, but the family should go to the hospital regularly. Under the guidance of medical staff, learn to check and correct the position of the ring.

Because of the small size of the ring, there is no obvious foreign body sensation in the depths of the vagina. If the same room has any influence, will it affect the contraceptive effect?

Ring-taking factor 2.

Do you want to take the children out?

After the intrauterine device is placed in the uterine cavity, the endometrium produces wonderful non-bacterial inflammatory reaction due to its special local function. It interferes with the combination of sperm and eggs and the development and growth of fertilized eggs in uterus, thus achieving the purpose of birth control. Of course, it can't be fixed after wearing the ring. When Xiao Li planned to have an abdominal MRI, the imaging doctor asked the gynecology department to take out the IUD for MRI examination. Avoid the influence of metal on image quality. In addition, due to the failure of conservative treatment, some complications of Sheung Wan can be considered, so the use cycle or menopause of Sheung Wan should be cleaned up in time.

The purpose of the ring is to use its life span to prevent pregnancy, because it is menopause and does not need to stay in the body. In addition, when releasing the IUD, the doctor places the appropriate IUD according to the size of the uterine cavity. After menopause, ovarian function and estrogen level decrease. The genitals begin to contract and tighten the cervix, but the IUD will not become smaller if it is not taken out in time. This makes it difficult to remove the ring. Therefore, menopausal women should take the ring in time and don't leave foreign bodies (pregnant objects) in the body.

Can we only follow the x-ray?

Monitoring and monitoring the situation of IUD can better play the role of IUD. Because this line meets the requirements and is cheap, most of the traditional rings are X-rays. So, can the ring only be X-ray? After Chopin's irregular menstruation, the doctor advised her to have an ultrasound examination to see the gestational age. Chopin wiped the doctor's face when he turned on the ultrasound. Sisters said the ring was on the X-ray. Why did the doctor turn on the ultrasound? The doctor said that ultrasound can check the intrauterine devices in the body, and some of them can't be seen under X-ray. Chopin doesn't know what ring he is wearing. According to the ultrasound, look at the uterus and accessories. Chopin was glad to hear this explanation.

In recent years, more and more people suggest that X-ray examination should be replaced by ultrasound examination as far as possible for three reasons. First, X-rays do harm to human body many times, so they are not suitable for long-term use. Second, the size of human uterus varies greatly. X-ray fluoroscopy can not correctly identify the position of the ring and the adjacent relationship between the ring and the uterus. This kind of ultrasonic examination has a third advantage. With the development of high technology, many contraceptive rings that can't pass X-ray have led to the development of X-ray fluoroscopy. In view of this view, it is gradually replaced by ultrasound examination.

3. Correctly understand the breeding circle.

The family planning department said that it can achieve the purpose of birth control without affecting sexual life, so it is welcomed by many women. It is simple, safe, effective and has few adverse reactions, and has become an important measure for women's postpartum contraception.

Under what circumstances is not suitable for the ring.

Acute pelvic inflammatory disease, acute vaginitis, severe cervical erosion. Otherwise, inflammation will increase menstrual flow.

What to pay attention to before and after the ring.

Although circular operation is simple and safe, infection can be avoided 3 days before operation and 2 weeks after operation, and the operation is the last one. Avoid uterine infection. Pay attention to rest 1~2 days after operation, and don't do heavy physical labor and a lot of exercise, because the cervix is easy to fall off when it has just been removed.

It is important to check whether the incubation ring falls off.

W

Since 1960, it has been widely used clinically in China. Some people don't have a correct understanding of intrauterine devices. Pathological examination of women of different ages showed that most patients had normal mild local inflammatory lesions. This change has no adverse effects on the human body, let alone cancer.

Intrauterine devices can last for several years.

The results show that stainless steel metal rings can be stored for 15~20 years, and silicone or other types of contraceptive rings can be stored for 5~7 years. There are obvious discomfort symptoms after putting on the ring, so it is necessary to put on the ring or change the ring or plan to get pregnant. Take the ring 3-7 days after menstruation is clean, and the precautions are the same as taking the ring. Postmenopausal women are no longer pregnant, so they no longer need contraception. Generally, the ring is put on within 6-3 years after menopause. It may be too late to put on the ring in the early stage, because menopause is unstable and contractions will bring difficulties to the ring.

Can I have a baby after going to Sheung Wan?

After taking out the pond, the interference of sperm and eggs disappeared and the endometrium returned to normal. Research shows that 75% of women get pregnant within 6 months after receiving the ring, and 90% of women get pregnant within 1 year after receiving the ring. After the removal of the ring, it has no effect on the development of the pregnant fetus. However, in order to repair and remove the endometrium well, other contraceptive methods must be used in the first three months of pregnancy.

What about the ring if you are pregnant?

Previously, it was thought that the pregnancy ring would not affect the fetus, nor would it cause fetal malformation. At this time, there is no need to terminate pregnancy or ring, and the fetus can be excreted through the placenta after birth. In recent years, the probability of finding ectopic pregnancy is slightly higher than that of general pregnancy.

4 What intrauterine devices are there in the uterus?

Inert intrauterine device: made of stainless steel wire or plastic silicon, such as metal single-ring torsion ring and stainless steel uterine ring.

Copper uterine protector: one of the most widely used active uterine protectors, which uses copper to kill sperm or fertilized eggs.

Intrauterine devices that release progesterone: In order to improve the contraceptive effect, progesterone contained in the uterus is slowly released into the uterine cavity, significantly reducing blood.

Intrauterine devices that release hemostatic drugs: After placing intrauterine devices, the increase of menstrual flow can be effectively controlled.

The foreign body effect of intrauterine device can cause asexual inflammation of endometrium and affect the implantation of fertilized eggs. In addition to the above functions, the copper IUD also has the functions of spermicide and embryo killing.

Contraceptive rings containing progesterone can release a small amount of progesterone to the uterus for a long time, which makes the endometrium contract, which is not conducive to the implantation of fertilized eggs. These two aspects further enhance the contraceptive effect of active IUD.

The second effect.

Non-pressure ovulation does not affect the female endocrine system, thus avoiding the adverse reactions of general drug contraception. Long-term contraception is harmless to health.

Does not affect sex life: many people like to wear condoms when they share a room, but they are not so interested and troublesome. Seriously affect the life of husband and wife.

Does not affect women's fertility: the baby's removal of the ring has no effect on the body.

Precautions.

It is suitable for placing intrauterine devices in uterus.

Intrauterine devices are placed in the uterus of women of childbearing age to prevent ovulation from affecting women's endocrine system through mechanical stimulation and chemical interference. So as to avoid the adverse reactions of common contraceptive drugs.

Eight golden ages suitable for Sheung Wan.

1 menstrual cycle: generally speaking, 3~7 days after menstruation is clean is more appropriate. At this time, the possibility of pregnancy is small, and the endometrium is thin. It is unlikely to cause injury and bleeding after placement. In foreign countries, it will also be placed during the menstrual period. Before placement, the possibility of pregnancy can be ruled out, the cervix will be more relaxed, and the psychological burden of uterine bleeding after placement can be avoided.

Placement immediately after induced abortion: placing animals or forceps with loose cervix immediately after induced abortion can avoid secondary operation, but it is important to ensure that the uterine contents completely eliminate bleeding, not contraction. Such as irregular vaginal bleeding before operation. If there is more bleeding during operation, uterine contraction is bad or it is suspected that the contents of uterine cavity are not completely removed, wait for the next crossing.

Placem

After 42 days of lactation, the uterine contraction recovered well, and there was no intrauterine or perineal infection for more than 5 days. You can place an intrauterine device. Reduce breastfeeding pregnancy. However, when the myometrium is weak, please be careful not to puncture.

Patients with caesarean section should be placed within half a year.

At the end of the storage period, if there are no symptoms, it can be replaced immediately.

Placement of placenta during delivery and immediately after caesarean section has the advantage of avoiding a second operation. If water is cut off for more than 12 hours, vaginal surgery, such as surgery, placenta, etc. It is easy to cause infection, so it is not suitable to place intrauterine devices. If placental residue is suspected, it is best not to put intrauterine device, because it will bleed. Classical caesarean section, because the uterine incision is located in the uterus, it is easy to embed or penetrate the uterine wall from the incision to the abdominal cavity, even if it needs to be placed. It must also be carried out in hospitals above the county level.

It's behind house no.8. After the accident, women who are worried about pregnancy and ready to take long-term pregnancy measures are worried about pregnancy. Because they didn't take contraception and contraceptive measures. The active copper IUD can be placed within 72 hours.

The above storage time is generally within 3-7 days after menstruation is clean.

Side effects.

The mechanism of uterine perforation is not clear. Generally speaking, it may be caused by inconsistent uterus size or improper operation by doctors. In addition, when women are exercising vigorously, the pregnancy ring in the body may also cause damage to the uterus due to the sharp shape of body inertia. Unexplained uterine contraction may also lead to uterine perforation.

In a few cases, IUD will cause uterine perforation into the abdominal cavity, leading to ectopic IUD. IUD can be separated from pelvis and mesentery in bladder.

Intrauterine devices with heavy menstrual flow contain copper ions, which are cytotoxic and hemolytic, with heavy menstrual flow and much bleeding.

Ectopic pregnancy is an ectopic pregnancy in which the embryo is implanted into the fallopian tube and does not reach the uterus. The birth control principle of IUD is to change the intrauterine environment, which leads to abortion only playing a local role in the uterus. Therefore, it can only prevent normal pregnancy, not ectopic pregnancy.

Endometrial fibrosis is essentially a foreign body in human body. It is common medical knowledge that foreign bodies in the human body can cause mechanical damage, chronic inflammation and fiber damage to local tissues. Endometrial fibrosis after 10~ 12 years.
