Product Description

Chitosan wound dressing

The chitosan dressings is a high-tech wound dressing which use chitosan fiber as raw material, the fiber is
extracted from the crabs, shells and others materials, the dressing not only has natural antibacterial,
hemostatic, promoting wound healing effect, but also has good bio-compatibility, biodegradability and
biological function.


Mechanism of action
Antibacterial and anti-inflammatory
It is the only efficient broad-spectrum biological dressing which doesn't contain any drug ingredient.
Promote healing:1. Promote growth of cells which related to wound healing, such as promote normal fibroblasts,
epithelial cells and keratinocytes growth; promote macrophages to produce the activity factor which contribute
to wound healing, thereby promote wound healing; 2. Promote microvascular regeneration of skin wound tissue,
improve blood circulation, thus speed up wound healing; 3. Chitosan dressing and cell interstitial mucopolysaccharide
matrix has similar molecular structure, it has good cell compatibility, provides a favorable environment for the
skin cell growth, it is conducive to wound healing.
Hemostasis:Chitosan is the only positive ion alkaline polysaccharide in nature, and act with the anion from the
surface of red blood cells, produce red blood cell aggregation. In addition, chitosan amino has adsorbed lipids
ability, the proportion of lipids on the red blood cell membrane is very big, through the adsorption of chitosan
amino to cell membrane lipid, it promotes its aggregation to achieve hemostasis purposes. Chitosan can also
promote platelet's PDGF-AB and TGF-β1 expression, and ultimately achieve the purpose of promoting platelet
adhesion and aggregation.
 Hygroscopicity and moisture retention:
Chitosan dressing is rich in amino group and a hydroxyl group; it is a natural substance of high hydrophilicity,
and its electrical charge and polar group density is very large, thereby it has superior moisturizing ability,
giving a comfortable feeling of wetness and softness to touch.
Analgesia:
Chitosan can absorb the wound inflammatory substances bradykinin in the blood (the bradykinin lead to pain),
then play an analgesic effect,
Inhibit scar's formation.
Chitosan can promote the growth of epithelial cells; inhibit abnormal overgrowth of fibroblasts to prevent scar
formation.
