Description

technical field

[0001] The present invention relates to a composition for lubrication of the birth canal, which can be administered during natural childbirth. Background technique

[0002] Childbirth is the period and process in which the fetus separates from the mother's body and exists as a separate entity. The natural delivery of the fetus through the birth canal is an extremely complicated process, which is usually accompanied by severe pain and different degrees of delivery injuries, especially for primiparous women. Therefore, assisted delivery has become the most necessary and most difficult and challenging work in the medical field.

[0003] The natural delivery of the fetus involves three main factors: childbirth, birth canal, and labor force. The childbirth includes the fetus, amniotic membrane, and placenta, etc. The birth canal is composed of two parts: the bony birth canal and the soft birth canal, and the labor force mainly comes from uterine contractions and ...
