Embodiment 1

[0032] The preparation method of physiological maintenance solution, comprises the steps:

[0033] (1) Take 10 parts by mass of raw materials rhubarb and 10 parts by mass of Radix Notoginseng; add 70% ethanol aqueous solution with a volume concentration of 7 times the mass of raw materials, heat and reflux for extraction twice, each time for 1.5h, combine the extracts, and concentrate under reduced pressure to The mass ratio of the quality of the concentrate to the amount of raw material is 2:1;

[0034] (2) Take 2 parts by mass of the raw material Wulingzhi, add water 6 times the mass of the raw material, decoct twice for 1 hour each time, combine the decoction liquid, and concentrate under reduced pressure until the mass ratio of the mass of the concentrated solution to the amount of medicinal materials is 1 : 1;

[0035] (3) the concentrated solution that step (1) and step (2) are obtained is combined into total concentrated solution, mixes, add the 5% hydroxypropyl trimet...

Embodiment 2

[0037] The preparation method of physiological maintenance solution, comprises the steps:

Abstract

The invention discloses a scar recovery dressing and a preparation method thereof. The scar recovery dressing is formed via sequential stacking of such raw materials as pressure-sensitive adhesive plaster, an electret film, a water absorbent cotton compression film, a physical curing film, a PE (polyurethane) anti-sticking mesh film and isolating protective paper. The electret film is formed via a way that constant-voltage corona charging is carried out at a polytetrafluoroethylene porous film at the room temperature via an ME-TL type high-voltage static corona system until static charges on the surface reach 200-20000V; and the physical curing film is formed via full saturation, taking-out and drying of a dressing in physical curing solution, and is prepared with such raw materials as hydroxypropyl trimethyl ammonium chloride chitosan or carboxymethyl chitosan, ethanol-extracted concentrate of rheum officinale and pseudo-ginseng, water-extracted trogopterus dung and a film forming agent. The physical treatment and chemical treatment can be achieved via the scar recover dressing for a scar, the scar curing can be promoted, the size of the scar can be reduced, and the good recoveryeffect can be achieved on the formed scar. Therefore, the scar recovery dressing has dual functions.

Description

technical field [0001] The invention relates to a scar repair patch and a preparation method thereof. Background technique [0002] "Scar" is the damage of physical, biological, chemical and other factors on the human skin and soft tissue, resulting in serious damage to the skin and soft tissue, which cannot be fully repaired normally by itself, and is replaced by fibrous tissue. Local symptoms that affect both appearance and function . What "scars" bring to patients is huge physical pain and mental pain, especially the scars left over from burns, scalds, and severe trauma. The several years of scar hyperplasia almost made the patient miserable. The subsequent atrophy period made the patient's scar parts, especially the face, completely unrecognizable and dysfunctional, causing the patient's great physical and mental obstacles. [0003] Keloids are raised, the epidermis is tumor-like hyperplasia, the surface is smooth, the color is rosy and shiny, and dilated capillaries ...
