Abstract

A compression bandage includes a bandage strip with an absorbent layer on one side. A pressure piece of slightly deformable and slightly absorbent molded material is attached to the other side of the strip opposite the absorbent layer. When the bandage is applied and the strip wound around the injured part, the pressure pad exerts pressure through the strip and absorbent layer onto the wound, and cannot slip from the correct position.

Claims

1. A compression bandage comprising a bandage strip having first and second sides, a pressure piece consisting of a molding of slightly deformable and slightly absorbent material firmly attached to said first side, and an absorbent layer fixed on said second side of said bandage strip in the region of said pressure piece whereby when the bandage is applied and the strip wound around the injured part, the pressure pad exerts pressure through the strip and absorbent layer onto the wound.

2. A compression bandage as claimed in claim 1, wherein, in area of cross-section parallel to said sides, the molded piece increases outwardly from said strip.

3. A compression bandage as claimed in claim 1, wherein said molded piece is of foamed plastics material.

4. A compression bandage as claimed in claim 1, wherein said molded piece is of polystyrene foam.

5. A compression bandage as claimed in claim 1, wherein in the longitudinal section and cross-section, the molded piece is approximately trapezoidal in shape, the trapezia having two parallel edges of which the shorter are in contact with said bandage strip.

6. A compression bandage as claimed in claim 1 and having, on said molded piece a top surface remote from the bandage strip which is of convex curvature.

7. A compression bandage as claimed in claim 1, wherein edges of the molded piece are rounded off, at least on the side of said moulding which is attached to said strip.

8. A compression bandage as claimed in claim 1, wherein corners of the molded piece are rounded off, at least on the side of said moulding which is attached to said strip.

9. A compression bandage as claimed in claim 1, wherein said molded piece is adhered to said bandage strip.

10. A compression bandage as claimed in claim 1, wherein said absorbent layer is adhered to said bandage strip.

11. A compression bandage as claimed in claim 1, wherein said bandage strip is elastically extendable in its longitudinal direction.

12. A compression bandage as claimed in claim 1, and having a self-adhesive finish to said bandage strip.
