Abstract
A multi-component dressing (100) for treating wounds of the human or animal body, using a reduced pressure, comprising a wound-covering element (4) for mounting the dressing (100) at the surface of the skin and the mucous membrane having at least one connecting site (5) through which material 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.
Claims10
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 connector configured to connect to a pressure reducing device and through which only gases in the wound space can be evacuated,
- the improvement wherein
- the dressing has super-absorbing polymers which absorb the wound secretions in the wound space;
- wherein the absorbed wound secretions, bound to the polymers, remain in the wound space until the polymers are removed;
- and
- wherein the polymers, due to their bonding capacity, support reciprocal synergies with the sub-atmospheric pressures.
A 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 sealed wound space, said wound covering element having at least one connector configured to connect to a pressure reducing device and through which only gases in the wound space can be evacuated whereby a sub-atmospheric pressure environment is provided in the wound space,
- a pressure reducing device connected to the at least one connector;
- and
- super-absorbing polymers which absorb wound secretions in the wound space;
- wherein
- 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 together with the sub-atmospheric pressure environment of the wound space, promote movement of secretions to the polymers.
