TECHNICAL FIELD
[0001] The utility model belongs to the field of medical cosmetology, and particularly relates to a freeze-dried collagen dressing. BACKGROUND
[0002] Collagen is the main component of animal extracellular matrix protein, accounting for 25%-30% of total human body protein. Collagen is composed of three polypeptide chains, and each polypeptide chain is a left-handed helical structure. The three left-handed helical chains are intertwined into a right-handed helical structure, and the three-helix structure has high tensile strength. Collagen has biodegradability, low cytotoxicity and low antigen activity. As a dressing, it can promote cell growth and adhesion, and can be used for wound repair after laser surgery, reduce postoperative pain and shorten the duration of pain, reduce pigmentation, accelerate wound repair, and also achieve the effects of nourishing the skin and improving the skin.
[0003] At present, the collagen protein paste dressing on the market is mainly composed of collagen stock solution and non-woven fabric. Its functions include repairing damage, moisturizing, reducing scar formation, reducing pigmentation, pain relief and hemostasis. Its clinical applications mainly include treatment of acne vulgaris, facial allergic dermatosis, facial burn wound healing treatment and nursing, facial laser, postoperative repair treatment after photon therapy, etc.
[0004] However, the existing collagen paste dressing on the market has the following deficiencies: 1. The common composition form is to mix collagen solution and non-woven fabric together for packaging and storage. During long-term storage, the dissolution of non-woven fabric greatly reduces the stability of collagen. Once the structure of collagen changes, the performance of the product will be reduced, and further more, it may cause an increase in the allergic rate; 2. Such products are usually recommended to be stored in a cold place or a cool place, and the storage and transportation process may also cause collagen degradation; 3. Most products are outsourced for radiation sterilization. In order to reduce the proliferation of microorganisms in this process, some preservatives are usually added. These preservatives may enter the human body and cause irritation and other adverse reactions during contact with the wound.
[0005] Freeze-drying technology uses low temperature and vacuum conditions to remove most of the water, thus preserving the natural structure and biological activity of biological materials such as collagen. It has important roles in many aspects: 1. Improve biocompatibility: maintaining the natural structure of the material helps it better compatible with human tissues in medical applications, reducing immune rejection, increasing safety and effectiveness of use; 2. Enhance therapeutic effect: the preservation of biological activity makes collagen better in promoting cell growth, tissue repair and regeneration, such as in wound healing, tissue engineering and regenerative medicine; 3. Optimize functionality: collagen with biological activity can more effectively penetrate the skin, promote collagen synthesis, and achieve anti-wrinkle, moisturizing and skin tightening effects; 4. Prolong product stability: biological materials treated by freeze-drying technology have enhanced stability and can be stored at room temperature, making transportation and storage easier and prolonging the shelf life; 5. No need to add preservatives, etc., the product is more pure, reducing the risk of potential irritation, allergy, etc. Practical new type content
