Claims20
A medical compress comprising:
- at least 8 layers of a textile web material, wherein each layer is connected to a further layer by at least one folded edge, and at least two folded edges are perpendicular to each other, the compress constructed from a rectangular material section of a web material, said rectangular material section having two parallel first cut edges located opposite each other and two parallel second cut edges located opposite each other, wherein a first edge length of said first cut edges is greater than a second edge length of said second cut edges, the compress being folded to generate an enclosing edge formed from at least one first folded edge and one second folded edge, wherein said first folded edge directly connects adjacent layers or partial sections of directly adjacent layers and is parallel to said second cut edges, said second folded edge connecting outer layers forming contact surfaces of the compress.
A method for manufacturing a medical compress having at least 8 layers of a textile web material, the method comprising the steps of:
- a) providing a rectangular material section of the web material with two first cut edges lying opposite each other and two second cut edges lying opposite each other, wherein a first edge length of the first cut edge is larger than a second edge length of the second cut edge;
- b) folding in the second cut edges of the rectangular material section along a first fold line parallel to the second cut edge and along a second fold line parallel to the second cut edge to generate two first folded edges;
- c) folding in at least one of the folded edges generated in step b) along a third fold line lying parallel to the second cut edge to generate a further folded edge;
- d) folding in the folded edge or the enclosing edge generated in step c) along a fourth fold line lying parallel to the second cut edge to generate an enclosing edge that comprises at least a first folded edge and a second folded edge;
- and
- e) further folding in of cut edges, formed folded or folded in edges to generate abutting edges, further folded or folded in edges, wherein each layer of the compress is connected to a further layer by at least one folded edge and at least two folded edges are perpendicular to each other.
