摘要：
The purpose of the notification is how to obtain dressings for the treatment of diabetic foot injuries and dressings obtained in this way. This means that a polyacrylonitrile solution containing silver nanoparticles is prepared to receive a prophylactic dressing by adding 20-30-nm-diameter 3% silver nanoparticles to the dimethylsfultolene and dispersing by ultrasonic homogeniser for a period of five minutes. After the solution has been obtained, it is supplemented with a granulated polyacrylonitrile and left to be completely dissolved for a period of 24h, resulting in the total concentration of the solution at level 7%,and then the solution is introduced into the chamber of the device to be transformed into micro and nano-fibers in an electrostatic field and subject to process conditions of 1 kV/cm, 1 ml/h, at eye temperature. 25oC, having obtained an antimicrobial material from which a shape of a certain size is cut and joins together in such a way as to surround the entire foot surface with material. constructed of four essential and interconnected layers,it is constructed of hydrophobic microfibres and/or a net to prevent adherence to the surface of the tissue of the first layer, placed above it a second layer with different properties and sometimes influences dependent on the introduced antimicrobial, antioxidative, angiogenic and a painkiller layer of a third layer of microfibres containing a water binding agent and finally a fourth layer of nanofibres with protective properties against mechanical agents and protection against microorganisms originating from the outside world.Przedmiotem zgłoszenia jest sposób otrzymywania materiałów opatrunkowych do zastosowania w leczeniu ran zespołu stopy cukrzycowej oraz materiały opatrunkowe otrzymane tym sposobem. Sposób ten polega na tym, że dla otrzymania opatrunku profilaktycznego przygotowuje się roztwór poliakrylonitrylu zawierający nanocząstki srebra, poprzez dodanie 3% nanocząstek srebra o średnicy 20 - 30 nm do di
