Midwifery gel preparation method

Abstract

The present invention discloses a new midwifery gel preparation method, which is designed by referring bionics and comprises three parts such as a drawing mucilage, a gel skeleton, and gel microspheres. According to the present invention, the drawing mucilage refers a organism lubricating liquid, adopts sodium hyaluronate as a main component, is added with carbopol so as to increase skin affinity, and is added with hydroxyethyl cellulose so as to adjust viscosity; the whole formula is similar to the formula of the lubricating liquid in the human body, and the same viscosity, the same drawing ability and the same skin affinity are provided; the network skeleton gel provides strong compressibility and strong film-forming property for the system, such that about 30 kPa pressure is generated to squeeze the gel so as to form the flowing elastic viscous film with a thickness of about 0.24 [mu]m when the fetus enters the birth canal; and the system is added with 50-100 nm sodium alginate gel microspheres, such that the original interlayer sliding friction of the gel is changed into the rolling friction so as to reduce the sliding friction, effectively reduce the static friction, such that the residence time is reduced, the injury and the pain during parturient uterine contraction are reduced, and the delivery time is shortened.

Description

technical field [0001] The invention relates to a preparation method of midwifery gel, which belongs to the field of biochemical medicine. Background technique [0002] Vaginal delivery of a baby is a complicated process. Obstetrics and gynecology studies have proved that delivery is determined by three factors: the delivery product (fetus, amnion, placenta), birth canal (composed of bone and soft tissue ducts), and labor force. Obstetrics and Gynecology Studies have shown that the force that promotes childbirth is uterine contraction and gravity, while the force that inhibits childbirth is the tension of the cervix and birth canal. [0003] The birth of a human baby is divided into three stages: the opening period, the delivery period and the postpartum period. Normal labor lasts an average of 12 hours for primiparas and 8 hours for multiparas. The reason for the shorter duration of labor on average in multiparas compared with primiparous women is that the tension of the ...

Problems solved by technology

[0019] However, the disadvantage is that, on the one hand, because the puerpera will have physiological fluids such as amniotic fluid and blood to flow out from the birth canal during childbirth, the lubricating effect of the lubricant composition will often be weakened. It is easy to clean, but has a better affinity for natural ingredients with lubricating properties, and will not weaken its lubricating effect with physiological body fluids. Therefore, the lubricating effect of the composition provided by the above technical solution is not good; and on the other hand, the reality The sentiment is that, because the maternal and fetal immune levels are low during childbirth, the birth canal is bleeding and episiotomy is often performed, and the chances of local and systemic infection are very likely to increase during childbirth, therefore, it is important to make midwifery lubrication It is very important that the lubricant has high-efficiency lubricating effect, safety and antibacterial properties, but the use of antibiotic chemicals in midwifery lubricants is often harmful to babies, and even very dangerous
