Abstract: The invention relates to a biodegradable graphene oxide biocomposite fibrous membrane and a preparation method and uses thereof. The composite fibrous membrane comprises biodegradable graphene oxide biocomposite fibers, each fiber has an outer layer consisting of graphene oxide-biodegradable polymer nanofibers and an inner layer consisting of sodium alginate/polyvinyl alcohol nanocomposite fibers. The biodegradable graphene oxide biocomposite fibrous membrane of the invention has the advantages of good biocompatibility, biodegradability, swellability, bacteriostasis and good mechanical properties and chemical stability.

Abstract: The present invention discloses a patella forming device and a using method thereof, the patella forming device comprising a connecting member, a base, a milling member and a central shaft pin, wherein the connecting member is disposed on the top of the base, and one end of the central shaft pin is disposed on the connecting member, The other end extends vertically downwardly and extends into the hollow structure of the base, the milling member is disposed on the surface of the base, and the base is rotatable around the central shaft to remove unwanted bone tissue through the milling member; The invention rapidly rotate on the surface of the patella which needs to be formed, and removes the skeletal hypertrophy bone and the bone tissue which is not matched with the femoral side prosthesis by cutting, honing, etc., forming a smooth and regular in a short time.

Abstract: The present invention provides an antibacterial wet wipe for skin care, which is prepared by adding an antibacterial skin care additive solution to a spunlaced non-woven fabric which is used as a base material, wherein the antibacterial skin care additive solution is prepared from the following components by mass fraction: Tea tree essential oil 5-10%, Nano silver 2-4%, Neroli essential oil 3-5%, Ceramide 1-1.5%, Glycerin 1-3%, Water-soluble vitamin E 0-3%, Emulsifier 0.1-0.5%, Deionized water balance. The preparation method of the antibacterial wet wipes for skin care is simple. And as adding the fungicides of tea tree essential oil and nano silver, and adding neroli essential oil, ceramide, glycerin, water-soluble vitamin E as moisturizing components, the antibacterial wet wipes for skin care of the invention not only have excellent antibacterial and disinfection effect, but also have whitening and moisturizing functions for skin care.
