OG exemplary drawing
 
1. A porous wound dressing for use in negative-pressure therapy of wounds, comprising:
an outer edge which defines an oval outer shape of the wound dressing, the wound dressing comprising a major axis and a minor axis;
a plurality of arc-shaped pre-cut lines, the pre-cut lines configured to serve for cutting the wound dressing to size in order to adapt the wound dressing to the size of a wound;
wherein each of the pre-cut lines extends asymmetrically with respect to the major axis and/or to the minor axis and encloses, 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,
wherein individual segments are arranged asymmetrically with respect to the major axis and/or to the minor axis and comprise an oval outer shape which corresponds to the oval outer shape of the wound dressing, such that an observer is able to readily recognize the oval outer shape of the wound dressing in the oval outer shape of the segment, and
wherein individual arc-shaped pre-cut lines are arranged at regular intervals from one another and individual arc-shaped pre-cut lines extend at least approximately parallel to one another, individual arc-shaped pre-cut lines extending from a first position on the outer edge of the wound dressing to a second position on the outer edge of the wound dressing, such that an oval-shaped division of the wound dressing into the segments is obtained.
 
12. A wound cover kit for use in negative-pressure therapy of wounds, comprising:
a wound contact layer configured to be placed directly against a wound;
a wound cover configured to be cover and seal the wound; and
a wound dressing comprising:
an outer edge which defines an oval outer shape of the wound dressing, the wound dressing comprising a major axis and a minor axis,
a plurality of arc-shaped pre-cut lines, the pre-cut lines configured to serve for cutting the wound dressing to size in order to adapt the wound dressing to the size of a wound,
wherein each of the pre-cut lines extends asymmetrically with respect to the major axis and/or to the minor axis and encloses, 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,
wherein individual segments are arranged asymmetrically with respect to the major axis and/or to the minor axis and comprise an oval outer shape which corresponds to the oval outer shape of the wound dressing, such that an observer is able to readily recognize the oval outer shape of the wound dressing in the oval outer shape of the segment, and
wherein individual arc-shaped pre-cut lines are arranged at regular intervals from one another and individual arc-shaped pre-cut lines extend at least approximately parallel to one another, individual arc-shaped pre-cut lines extending from a first position on the outer edge of the wound dressing to a second position on and to a further portion of the outer edge of the wound dressing, such that an oval-shaped division of the wound dressing into the segments is obtained.
