Embodiment 1
[0036] The dosage form of the biological dressing provided by the present embodiment is a gel, which includes the following components by weight percentage:
[0038] Component B: 89.15% ultrapure water, 0.05% disodium EDTA, 10% mass fraction of 2% carboxymethyl cellulose solution, 0.75% mass fraction of 20% sodium hydroxide solution and 0.05% nitric acid Parkin methyl ester;
[0039] The mass ratio of component A to component B is 1:2.
[0040] The preparation method is:
[0041] 1) Fully swell the carbomer in hot water at 80°C for 30 minutes to form a gel matrix. After cooling to room temperature, add other components in part A under the condition of stirring speed of 500r / min, stir for 15-25 minutes and mix evenly. Stirring can be stopped:
[0042] 2) Dissolve carboxymethyl ce...

Abstract
The invention discloses a biological dressing with a scar prevention function and a preparation method thereof.The biological dressing comprises a component A and a component B. The component A and the component B have the scar removal and itching relieving functions, the dosage form of the biological dressing comprises gel or cream, the component A comprises a mussel extract and an onion extract, the mussel extract contains an L Dopa group, the onion extract contains an L Dopa group, and the onion extract contains an L Dopa group. L Dopa is combined with an epidermal nerve ending receptor to seal epidermal nerve endings to achieve the itching relieving effect, meanwhile, lysine is contained, mussel mucoprotein becomes a very few basic protein, molecules carry a large number of positive charges in the physiological environment, sick cells are recovered in time, the itching relieving effect is achieved, nerve endings can be passivated through electrostatic interaction, and the effect of relieving itching is achieved. The itching relieving effect is achieved. The biological dressing disclosed by the invention not only can prevent the formation of scars, but also can relieve skin itch, and can improve the appearance, erythema and height of hyperplastic scars of patients when being used for the hyperplastic scars.
Description
technical field [0001] The invention belongs to the field of medical biomaterials, and relates to a biological dressing, in particular to a biological dressing capable of alleviating the itching of patients' scars, improving the appearance of hypertrophic scars, erythema and high degree of scar prevention, and a preparation method thereof. Background technique [0002] A wound is a breach of the integrity and continuity of the human skin. In daily life, there are many types of wounds, including cuts caused by mechanical factors, burns caused by factors such as electricity, heat, and chemicals, and chronic wounds caused by the patient's physiological morbidity. Various wounds on the surface of the human body are unavoidable common symptoms in life. The longer the healing of the wound is delayed, the harder it is for the scars to disappear after healing. Everyone has a desire for beauty, and for most women, they all hope to have smooth skin. Once scars appear, it will bring ...
