Abstract

The invention relates to a multi-component dressing (100) for treating wounds of the human or animal body using a reduced pressure, having a wound-covering element (4) for mounting the dressing (100) at the surface of the skin and the mucous membrane and at least one connecting site (5), which is in contact with the wound space (10) and over which the materials in the wound space (10) can be evacuated. The multi-component dressing has super-absorbing polymers, the absorbed wound secretions remaining bound to polymers in the wound space until the latter are removed from the wound space and the polymers, due to their binding capacity, supporting reciprocal synergies with the sub-atmospheric pressures. Wound exudate, promoted by the reduced pressure, is also stored and controlled by polymerized granulates.

Claims

1. A multi-component wound dressing for treating a wound on a human or animal body using a reduced pressure, said dressing comprising a wound covering element adapted to be applied to the surface of the skin to cover the wound, thereby forming a wound space, said wound covering element having

at least one connected through which material in the wound space can be evacuated,

wherein

the dressing has super-absorbing polymers, which absorb secretors in the wound space

the absorbed wound secretions, bound to the polymers, remain in the wound space until the polymers are removed;

and

the polymers, due to their bonding capacity, support reciprocal synergies with the sub-atmospheric pressures.
