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.
Claims17
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 with a major axis and a minor axis,
- one or more incisions or perforations which together form a plurality of arc-shaped lines and 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 arc-shaped 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 the segments, which in each case are enclosed by one of the arc-shaped lines and the respective portion of the outer edge, are each arranged asymmetrically with respect to the major axis and/or to the minor axis, and in each case have 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 the arc-shaped lines are arranged at regular intervals from one another and extend at least approximately parallel to one another and to a further portion of the outer edge of the wound dressing, such that a mussel-shaped division of the wound dressing into the segments is obtained.
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 oval outer shape of the wound dressing with a major axis and a minor axis,
- one or more incisions or perforations which together form a plurality of arc-shaped lines and 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 arc-shaped 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 the segments, which in each case are enclosed by one of the arc-shaped lines and the respective portion of the outer edge, are each arranged asymmetrically with respect to the major axis and/or to the minor axis,
- and in each case have 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 or segments, and
- wherein the arc-shaped lines are arranged at regular intervals from one another and extend at least approximately parallel to one another and to a further portion of the outer edge of the wound dressing, such that a mussel-shaped division of the wound dressing into the segments is obtained.
