Abstract
A porous wound dressing for use in negative-pressure therapy is proposed. The wound dressing has an outer edge which defines a substantially oval or rectangular outer shape of the wound dressing with a major axis and a minor axis. The wound dressing has one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound. The one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing.

A porous wound dressing for use in negative-pressure therapy of wounds, comprising an outer edge which defines an outer shape of the wound dressing with a major axis and a minor axis, one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound, wherein the one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing and for subsequent use in the negative-pressure therapy of wounds.
The wound cover kit for use in negative-pressure therapy of wounds, having
- a wound-side contact sheet designed to be placed directly on a wound;
- a covering which serves to cover and seal off the wound area from the outside;
- and
- a porous wound dressing comprising
- an outer edge which defines an outer shape of the wound dressing with a major axis and a minor axis,
- one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound,
- wherein the one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing and for subsequent use in the negative-pressure therapy of wounds.
