preparation example Construction

[0051] The preparation process of the biological nutritional dressing of embodiment 1-9 is the same, as follows:

[0052] First dissolve chitosan and polyvinyl alcohol with water respectively to obtain the aqueous solution of the two, take the aqueous polyvinyl alcohol solution, gradually add nano-silk fibroin, minerals, vitamins, peppermint oil, etc. to dissolve it while stirring, mix well, and then Add the chitosan solution and stir to mix well. It is poured on the mold with non-woven fabric laid on the bottom, and the thickness is controlled at 0.1-0.5cm. Put it in a low-temperature environment for a period of time, freeze it to form a gel / non-woven fabric, take it out and freeze-dry (the temperature used is the same as the freezing temperature), and then the biological nutritional dressing is obtained.

[0053] The freezing temperature, time and freeze-drying time of each embodiment are shown in Table 2.

Abstract

The invention provides a biological nutrition dressing for thoroughly treating skin injury and a preparation method thereof. The biological nutrition dressing is a gel which is mainly prepared from the following components in percentage by weight: 0-5.0% of nanometer silk fibroin, 0.15-8.0% of mineral substance, 0.01-0.2% of vitamin, 0.1-0.5% of peppermint oil, 1.0-3.0% of chitosan, 1-5% of polyvinyl alcohol and balance of water. The preparation method comprises the steps of mixing and dissolving all the raw materials according to the formula, and then carrying out freeze drying under -20-0DEG C to obtain the product. The biological nutrition dressing for thoroughly treating skin injury solves the technical problems of single treatment approach and poor healing effect on hard-to-heal wounds.

Description

technical field [0001] The invention relates to the field of skin wound repairing drugs, in particular to a biological nutritional dressing for comprehensively treating skin wounds and a preparation method thereof. Background technique [0002] The skin is an important organ of the human body and plays a protective role for the human body. Skin damage will cause a series of problems in the body, such as bacterial infection, increased metabolism, excessive loss of water and protein, endocrine and immune system dysfunction, etc., which may be life-threatening in severe cases. Therefore, after skin injury, it is usually necessary to use medical dressings to protect the wound, prevent wound infection and severe dehydration, provide an environment conducive to wound healing, and promote wound healing. Especially in the field of chronic difficult-to-heal wounds, the role of medical dressings that can promote wound repair is very important. [0003] An ideal medical wound dressin...
