Abstract
A multi-layered wound care product includes an upper liquid-absorbing layer, an intermediate occlusive layer; and an active agent-releasing bottom layer. The latter two layers have common pores or perforations that enable the passage of wound exudate through the two layers to reach the liquid-absorbing layer. A use of the multi-layered wound care product for treatment of acute and chronic wounds and a method of producing the multi-layered wound care product are also provided.
Claims19
A multilayered wound care product comprising:
- an upper liquid-absorbing layer;
- an intermediate occlusive layer;
- and
- a bottom active agent-releasing layer;
- wherein the occlusive layer and the active agent-releasing layer are sheet-like layers with pores or perforations, wherein each pore or perforation is a common pore or perforation that extends through a whole thickness of both the intermediate occlusive layer and the active agent-releasing layer that enable a passage of wound exudate through the common pores or perforations of such two layers to reach the liquid-absorbing layer and simultaneously enable a release of an active agent from an area between the pores or perforations to enter a wound site, and
- wherein the occlusive layer is impermeable for fluids and prevents the active agent from spreading to the upper liquid-absorbing layer.
