| titleOfInvention | Gel for midwifery and preparation method thereof |
| abstract | The invention discloses a novel preparation method of midwifery gel. The invention refers to the bionic design and is composed of wire-drawing mucus, a gel framework and gel microspheres 3. The drawing mucus is prepared from sodium hyaluronate as main component, carbomer for improving skin affinity, and hydroxyethyl cellulose for regulating viscosity. The whole formula is similar to the lubricating liquid in human body, and has the same viscosity, the same stringiness and skin-friendly ability. The network skeleton gel provides strong compressibility and film forming property for the system. When the fetus enters the birth canal, a pressure of about 30kPa is generated, and the extruded gel forms a flowing elastic mucosa with a thickness of 0.24 μm. The sodium alginate gel microspheres with the particle size of 50-100nm are added into the system, so that the original interlayer sliding friction of the gel is changed into rolling friction, the sliding friction is reduced, the static friction force can be effectively reduced, the residence time is reduced, the damage and pain of the puerpera during uterine contraction are reduced, and the delivery time is shortened. |
