Abstract
A tissue dressing material for being applied in contact with a tissue of a patient. The tissue dressing material's main component is deacetylated native chitosan. Moreover, a liquid tissue dressing material for being applied in contact with a tissue of a patient, the tissue dressing material being an aqueous mixture. The main component of the constituent(s) of the mixture other than water is deacetylated native chitosan.
Claims16
A tissue dressing material for being applied in contact with a tissue of a patient comprising at least 50% by weight native chitosan having a degree of acetylation below 2.5%, wherein the water uptake capacity of a solid phase of the tissue dressing material is less than 100% by weight.
A liquid tissue dressing material for being applied in contact with a tissue of a patient, the tissue dressing material being an aqueous mixture comprising at least 50% by weight of the combination of all constituents other than water native chitosan having a degree of acetylation below 2.5%, wherein the tissue dressing material has a pH above 4.5.
A method of treating a tissue of a patient, comprising a step of applying a tissue dressing material in contact with the tissue of the patient,
- the tissue dressing material comprising at least 50% by weight native chitosan having a degree of acetylation below 2.5%,
- wherein the water uptake capacity of a solid phase of the tissue dressing material is less than 100% by weight.
A method of treating a tissue of a patient, comprising a step of
- applying a liquid tissue dressing material in contact with the tissue of the patient, the tissue dressing material being an aqueous mixture, the tissue dressing material comprising at least 50% by weight of the combination of all constituents other than water, native chitosan, having a degree of acetylation below 2.5%, wherein the tissue dressing material has a pH above 4.5.
