Abstract:
1. An absorptive body for attachment to the human body, particularly for the purpose of absorbing fluids exiting the human body from a wound, said absorptive body comprising: (a) an essentially flat material section of absorptive material having an absorptive surface area on at least one side, said absorptive material including an absorptive fleece with super-absorber particles embedded in it; and (b) a moisture-permeable shell having an external surface area covering the absorptive surface area of the absorptive material and forming a barrier against solid excretions from a wound while allowing liquid substances from the wound to penetrate into the absorptive material, said shell having a seam in the surface area thereof which surrounds the material section to seal the material section within the shell; the improvement wherein the absorptive surface area of the material section, in its unwetted state, is 3% to 75% smaller than the external surface area of the shell when laid flat, wherein the shell includes pores across its external surface area, each of which is smaller than the super-absorber particles, in an unwetted state, and wherein the external surface area of the shell has an overlap area extending outward, with respect to the absorptive material, beyond the seam at every point around the seam.
