The present invention provides an absorbent wound dressing assembly that can be used to stanch, seal, or stabilize a site of tissue injury, tissue trauma, or tissue access. The wound dressing assembly is flexible so that it can be adapted and used to fit in narrow and small wound sites. Generally the wound dressing assembly comprises a flexible carrier material that is impreg-nated with a non-mammalian material for control of severe bleeding. The preferred non-mammalian material is poly [(.beta.- (1-.fwdarw.4) -2- amino-2-deoxy-D-glucopyranose] more commonly referred to as chitosan.

La présente invention concerne un ensemble pansement absorbant qui peut être utilisé pour arrêter les saignements, fermer hermétiquement ou stabiliser un site de lésion tissulaire, de traumatisme tissulaire ou daccès à un tissu.

Dune manière générale, lensemble pansement comprend un matériau porteur souple qui est imprégné dun matériau non-mammifère destiné à contrôler les hémorragies graves. Le matériau non-mammifère préféré est le poly[ß-(1?4)-2-amino-2-déoxy-D-glucopyranose], plus communément appelé chitosane.
