| 摘要 |
In one embodiment, the present invention is a multi-layered bandage including a wound-contacting first layer which is porous, fluid-permeable, biodegradable, and capable of accelerating hemostasis and wound healing, and a second layer formed from an absorbent material which is releasably secured to the first layer. The first layer includes a porous, fluid-permeable, biodegradable lattice structure formed from a homogeneous mixture of collagen and a clotting enzyme which, as healing occurs, may be replaced by new tissue. The second layer may be detached at a time deemed safe, usually immediately after hemostasis occurs, without disturbing the healing process. |

1. A multilayer bandage comprising
a first layer for contacting a wound comprising a porous, fluid-permeable, biodegradable lattice structure formed from a homogeneous mixture of collagen and a clotting enzyme; and a second layer releasably secured to the first layer comprising an absorbent material, wherein the bandage is adapted to allow flow of a fluid from the wound into the first layer to interact with the clotting enzyme to promote clot formation and, optionally, through the first layer and into the second layer. |
