Chitin-based
Non-woven material manufactured from chitin. Available
in Japan since 1982.
Favours early granulation, no retractive scar formation.
For traumatic wounds, surgical tissue defects
Beschitin
Unitika
Made of chitin microi brils from the centric diatom
h alassiosira l uviatilis
grown under aseptic conditions
It is claimed to be 7 times faster in achieving haemostasis
than i brin glue, because it agglutinates red blood cells,
activates platelets whose pseudopodia make a robust
contact with chitin and promotes i brin gel formation
within the patch, thus acting in a redundant way even
on heparinised patients

Chitosan-based
Chitosan powder with adsorbed elementary iodine
For the disinfection and cleaning of wounded skin and for
surgical dressing
Chitodine
IMS
Antibacterial, biocompatible wound dressing designed to be
stuf ed into a wound track
Foe controlling moderate to severe bleeding. It adheres
strongly to tissue surfaces forming a l exible barrier that
seals and stabilises the wound surface. Easily removed
with saline or water
ChitoFlex
HemCon
Cotton-like chitosan obtained by spinning chitosan acetate
salt into a coagulating bath of ethylene glycol, ice and
NaOH; i bers washed with water and methanol
Complete reconstruction of body tissue, rebuilding of
normal subcutaneous tissue and regular regeneration
of skin
