The present invention provides novel polyurethane-based wound dressing foams, obtained by foaming and curing silane-terminated polyurethanes.

Production of polyurethane foams for wound management

The invention relates to a process for producing polyurethane foams, by frothing and drying mixtures of specific polyurethane dispersions and crosslinkers.

Production of polyurethane foams

The present invention relates to biomedical foam articles for the wound sector which are formed by spraying a polymeric dispersion onto a wound. The polymeric dispersion being sprayed onto a wound surface forms a three-dimensional body which conforms to the spatial shape of the wound and which, as well as covering the wound surface, ensures a complete and accurately fitted packing of the wound in the depth dimension as well as the other dimensions. The biomedical foam articles of the present invention are particularly useful for treating chronic wounds.

Biomedical foam articles

The present invention describes microbicidal hydrophilic polyurethane foams endowed with polyhexamethylenebiguanide (PHMB) and/or its hydrochloride and also a superabsorbent, wound contact materials obtainable therefrom and processes for producing the therapeutically endowed polyurethane foams and the wound contact materials obtainable therefrom.

Infection-resistant polyurethane foams, method for producing the same and use thereof in antiseptic wound dressings
