Suzhou Soho Biomaterials Co., Ltd. has made about 10g of raw silk dressing for about 20g of raw silk in the past 7 years, replacing the allogeneic and xenogeneic skin graft for the repair of burn wounds, which can reduce pain and shorten Wound healing time. The advent of this product means that silk was first used in the field of medical devices. It is reported that the "silk" device has also obtained the registration certificate for the first time product issued by the Food and Drug Administration.
The reporter saw that this silk protein wound dressing is not very different from ordinary medical tape, but careful observation reveals that there are small pores on it. R & D, production company - Suzhou Soho Biomaterials Technology Co., Ltd. General Manager Chen Liming told reporters that the dressing is not as simple as ordinary tape, it is composed of two layers, the upper layer in contact with air is a transparent medical silicone rubber film, Direct contact with the wound surface is made of natural silk fibroin as a raw material, and the technology content is very high. The company has obtained a number of national invention patents. It is understood that after the successful development of the product, in accordance with the provisions of the State Food and Drug Administration, the clinical application of silk protein wound dressings was verified at the clinical laboratory bases of Ruijin Hospital affiliated to Shanghai Jiaotong University Medical College and Nantong University Affiliated Hospital. The results showed that silk protein Wound dressing has reliable safety, promotes wound healing, improves wound healing rate, and relieves pain in patients.
According to Chen Liming, there are three types of burns, and this silk protein wound dressing is mainly suitable for deep second degree burns and shallow second degree burns. Originally, these two types of burns were generally transplanted with allogeneic skin or xenogenic skin. However, allogeneic There are a small number of skins and the risk of carrying viruses. The heterologous skin is mainly pig skin, and there are religious ethnic limitations during use. In addition, the price of silk protein wound dressings is only half the price of xenogenic skin and allogeneic skin. If burn patients use pig skin grafts, they should be replaced about every three days, but silk protein wound dressings can be cured once in most cases until the silk protein wound dressing falls off from the wound surface, reducing the patient's pain and financial burden. Compared with allogeneic skin and xenogeneic skin grafting, silk protein wound dressing can shorten the healing time of burns. "The healing time of shallow second degree burn can be shortened by 5-7 days, and deep second degree burn can be shortened by 3-4 days." Chen Liming said.
It is understood that the silk protein wound dressing only entered the sales field at the beginning of this year. As an emerging product, it has achieved gratifying sales results in half a year, and has passed the tender of dozens of hospitals. Chen Liming said that this silk protein wound dressing will replace allogeneic skin and xenogenic skin grafts and become the mainstream dressing for the treatment of burns. In addition, Chen Liming revealed that the company has developed a high-tech human skin that can replace autologous dermal grafts for deep burns and trauma-induced dermal defect wounds. It will be marketed after obtaining relevant registration certificates.
At present, this dressing has been certified by relevant departments and entered 34 hospitals nationwide through bidding. At present, the company's annual production capacity is 10,000, and it is likely to increase to about 50,000 in the future. “Bringing silk from the traditional textile industry into the bio-pharmaceutical industry and making medical materials directly applied to the human body is very rare in the industry. At present, we are working with Suzhou University, Shanghai Ruijin Hospital and other units to develop silk protein. New artificial skin, this artificial skin can be used to treat dermis defects caused by deep burns and trauma, and future silk will have a greater role in biomedicine," said Chen Liming.
