Summary: | The invention relates to a collagen biomaterial for treating the skin infections produced by the bacteria S. aureus and P. aeruginosa and to a process for preparing the same. According to the invention, the biomaterial consists of a natural polymer - fibrillar collagen type I - as gel, with native triple helix structure, a natural tribomechanically activated zeolite - clinoptilolite, an Origanum or Thymbra spicata L. essential oil and a cross-linking agent. According to the invention, the process consists in treating the zeolite with essential oil, the resulting suspension is added to the collagen gel, is homogenized, the pH is adjusted to 7.4 and there is added distilled water until the final composition contains 1.2% collagen as dry substance and then it is cross-linked, after which the resulting composition as suspension is frozen immediately, is dried by lyophilization, there resulting a spongy collagen biomaterial.
Invenţia se referă la un biomaterial colagenic, pentru tratarea infecţiilor pielii, produse de bacteriileşi, şi la un procedeu de obţinere a acestuia. Biomaterialul conform invenţiei este constituit dintr-un polimer natural - colagen fibrilar tip I - sub formă de gel, cu structură nativă de triplu helix, un zeolit natural - clinoptilolit activat tribomecanic, un ulei esenţial desauşi un agent de reticulare. Procedeul conform invenţiei constă din tratarea zeolitului cu ulei esenţial, suspensia rezultată se adaugă peste colagenul gel, se omogenizează, se ajusteazăH-ul la 7,4 şi se adaugă apă distilată, până când compoziţia finală conţine 1,2 % colagen substanţă uscată şi apoi se reticulează, după care, compoziţia rezultată sub formă de suspensie se îngheaţă imediat, se usucă prin liofilizare, din care rezultă biomaterialul colagenic spongios. |
