Abstract
Abstract In order to stimulate the formation of new tissues in extensive and deep wounds, the tissues are eased by exerting a traction force on the tissue with a vertical force component in relation to the plane of the wound. If the wound is vacuum sealed by a plastic foil (F), traction may be exerted through the foil (F). If a distractor that acts in the plane of the wound is set at the wound edges, the vertical traction component may be exerted on the edges of the wound by this distractor. The vertical traction component is generated through turnbuckles (70).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
Process for stimulation of formation of new tissue in large surface area and deep wounds, said process comprising exerting a negative pressure upon the tissue, wherein for attaining the negative pressure mechanical draw a pull force acting at an angle to the plane of the wound field is exercised upon the tissue, wherein the wound field is covered over by an air tight plastic foil, which is sealingly secured to the wound edge, and wherein the mechanical draw pull force engages in the area of the wound field on the plastic foil.
Claim 2
Dependent Claim
92 words
Process for stimulation of formation of new tissue in large surface area and deep wounds, said process comprising exerting a negative pressure upon the tissue, wherein for attaining the negative pressure mechanical draw a pull force acting at an angle to the plane of the wound field is exercised upon the tissue, wherein the wound field is covered over by an air tight plastic foil, which is sealingly secured to the wound edge, and wherein the mechanical draw pull force engages in the area of the wound field on the plastic foil.
Claim 3
Dependent Claim
26 words
Process according to claim 1, wherein at least one drainage tube connected to a suction source is introduced into the wound field under the plastic foil.
Claim 4
Dependent Claim
26 words
Process according to claim 2, wherein at least one porus foam material layer is laid in the wound field, into which the drainage tube is introduced.
Claim 5
Dependent Claim
56 words
Process according to claim 1, wherein the wound field is covered over by an air tight plastic foil, which is sealingly secured to the wound edge, and at least a porous foam material layer is laid in the wound field under the plastic foil, wherein the pull force engages on one of the foam material layers.
Claim 6
Dependent Claim
69 words
Process for stimulation of formation of new tissue in large surface area and deep wounds, extending through cut is said process comprising exerting a negative pressure upon the tissue, wherein for attaining the negative pressure a pull force acting at an angle to the plane of the wound field is exercised upon the tissue, via at least one element which engages the cutis near the edge of the wound.
Claim 7
Dependent Claim
69 words
Process for stimulation of formation of new tissue in large surface area and deep wounds, extending through cut is said process comprising exerting a negative pressure upon the tissue, wherein for attaining the negative pressure a pull force acting at an angle to the plane of the wound field is exercised upon the tissue, via at least one element which engages the cutis near the edge of the wound.
Claim 8
Dependent Claim
57 words
Process according to claim 5, wherein a pull force is exercised acting horizontally on the plane of the wound field and additionally also a vertical pull force is exercised acting at an angle to the plane of the wound via at least two elements positioned on opposite sides of the wound edge and engaging in the cutis.
