Abstract

Przedstawiony na schemacie sposób wytwarzania protezy ucha srodkowego z tworzywa polimerowego technologia wtryskowa, polega na wysuszeniu granulatu polimeru termoplastycznego, korzystnie polietylenu o wysokiej gestosci lub poliamidu lub polisulfonu, w temperaturze od 60 do 150°C przez okres od 2 do 8 godzin, uplastycznieniu go oraz wtrysku w temperaturze od 180 do 400°C, do ogrzanej do temperatury od 60 do 150°C formy. Uzyskana ksztaltka jest chlodzona, zas w koncowym etapie poddana prózniowemu foliowaniu hermetycznemu i sterylizacji. Dodatkowo jako granulat polimeru termoplastycznego stosuje sie granulat kompozytowy, uzyskany przez wprowadzenie do granulatu polimeru termoplastycznego bakteriobójczego dodatku modyfikujacego, korzystnie proszku srebra o rozmiarach czastek od 15 do 100 nm, w ilosci 0,1-3% wagowych.
