Absorption Body For Attachment To The Human Body
Patent #: 7,335,809
Inventor(s): Birgit Riesinger
An absorptive body for attachment to the human body has been patented. The item is designed particularly for the purpose of absorbing fluids exiting the human body from a wound. The absorptive body comprises an essentially flat material section of absorptive material with an absorptive surface area on at least one side. The absorptive material includes an absorptive fleece with superabsorbent particles embedded in it. A moisture-permeable shell has an external surface area covering the absorptive surface area of the absorptive material and forms a barrier against solid excretions from a wound while allowing liquid substances from the wound to penetrate into the absorptive material. The shell has a seam in the surface area that surrounds the material section to seal the material section within the shell. The improvement of 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. The shell includes pores across its external surface area, each of which is smaller than the superabsorbent particles in an unwetted state. 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.
