【Product Description】
Sidaiyi is a disposable medical biological sterile wound dressing made from natural silk fibroin. It adopts a unique double-layer structure design, with the upper layer of silicone rubber membrane, which can block bacteria and maintain the wet environment of the wound, and the lower layer of porous silk fibroin membrane, which can guide the regeneration of tissues and absorb the wound exudate. The product has excellent flexibility and compliance. Under the wet state, it can be very good compliance with the wound tissue, and can be used for a variety of clinical wound tissue repair.

【Core Advantages】
•The 18 kinds of amino acids that make up silk fibroin are similar to the composition of human skin. The internal structure of silk has 87% similarity to human skin, which makes the film less irritating to human skin, non-toxic side effects, and good biocompatibility.
•The natural porous structure of silk fibroin biomaterials can guide the adhesive,growth and migration of newborn cells, and promote faster wound healing.
•The natural porous structure of silk fibroin provides abundant accommodation space, has strong water absorption capabilities, effectively absorbs wound exudate and prevents infection.
•Silk fibroin biomaterial has good water-holding properties, provides a moist microenvironment for the wound while sealing it and promotes wound healing.
•The dense porous structure of silk fibroin biomaterial can guide the regular growth of cells while avoid the growth of new granules and tissues into the pore space of the dressing, so that it can be easily removed or naturally dislodged when changing the dressing in the clinic, thus reducing the patient's pain.
•Silk fibroin biomaterial has a light transmittance of over 90% in the visible light range of wavelengths 380-780nm, which facilitates dynamic observation of wound healing.
•The outer medical silicone membrane structure effectively prevents bacterial invasion and reduces excessive loss of protein, moisture and ions.
•The two spatial conformations of silk fibroin structures can be converted by different physical and chemical conditions, which makes silk fibroin have good mechanical strength and ductility along its long axis, possessing good compliance and facilitating the coverage of wounds at different angles.

【Intended Usage】
Used for non-chronic wound care, such as clinical I degree and superficial Ⅱ degree burns, wound care in trauma surgery, wound repair department, and cosmetic plastic surgery department.
•Burns department: For adjuvant treatment of I degree and superficial Ⅱ degree burn wounds.
•Wound repair department:  For adjuvant treatment of diabetic foot, pressure sores, ulcers, and iatrogenic wounds.
•Trauma surgery department: For adjuvant treatment of non-chronic wounds such as superficial wounds, post-surgical sutured wounds, mechanical trauma, minor cuts, abrasions, incision wounds, puncture sites from puncture instruments.
•Aesthetic plastic surgery department: For adjuvant treatment of postoperative wounds from procedures such as laser treatment, photo skin rejuvenation, fruit acid resurfacing, and micro-plastic surgery.
