Background

In the body of a pregnant woman, amnion is used as the inner membrane of the fetal membrane, and the fetus is wrapped in the amniotic sac cavity which is filled with amniotic fluid. In the gestation period, the amniotic fluid has multiple effects on the fetus, not only is the natural protective barrier of the fetus, relieves the damage of external impact on the fetus, protects the fetus and prevents the joint fixation, the limb deformity and the limb adhesion of the fetus; the development and the activity of the fetus are facilitated, sufficient amniotic fluid can provide sufficient activity space and nutrition requirements for the fetus, and the fetus can do proper breathing movement and limb movement in the uterine cavity; meanwhile, the amniotic fluid has the function of heat preservation, can keep the constant temperature in the uterus, and enables the fetus to grow in a constant-temperature and stable environment; it can provide nutrition for fetus, and in the body of pregnant woman, the nutrition of fetus can be obtained from placenta, and also can be taken from amniotic fluid. Therefore, adequate and normal quality amniotic fluid is essential for the development of the fetus. Under normal conditions, the pregnant woman can maintain sufficient and normal amniotic fluid, but the quality of the amniotic fluid in the pregnant woman is gradually reduced along with the prolongation of the pregnancy period, and the quality of the amniotic fluid is also changed to a certain extent; if the condition that the amniotic fluid in the body of the pregnant woman is too little or the amniotic fluid is polluted due to diseases occurs, the umbilical cord and the placenta are directly pressed between the uterine wall and the tyre body when the uterus contracts, so that the fetal distress, insufficient blood supply and oxygen supply are caused, and even the fetal deformity and the life risk in the delivery of the fetus are caused. At present, patients with oligohydramnios and pollution are generally treated by intravenous fluid infusion, and the treatment speed is low and the effect is poor. The symptoms are severe, and generally, amniotic fluid perfusion is adopted, namely warm saline is slowly injected into an amniotic cavity through a puncture needle. This method is faster than intravenous infusion, but less safe. During the perfusion, the puncture needle head is inserted into the amnion cavity, when a fetus and a pregnant woman move, the fetus is easy to be damaged, and the use is unsafe.
