Abstract
An absorbent structure comprising a silicone foam having pore walls and a plurality of hydrophilic particles anchored to the pore walls of the foam. Some of the hydrophilic particles have an anchored portion firmly anchored to the pore walls and an exposed portion extending outwardly away from the pore walls upon which the anchored portion is secured.
Claims15
An absorbent structure for a prosthetic device comprising:
- a porous substrate in the form of an inner sleeve and having pore walls;
- and
- a plurality of hydrophilic particles anchored to the pore walls of the porous substrate, wherein a portion of the plurality of the hydrophilic particles have an anchored portion anchored to the pore walls and an exposed portion extending outwardly away from the pore wall upon which the anchored portion is anchored.
An absorbent structure comprising:
- a hydrophobic, polymeric porous substrate;
- and
- a plurality of hydrophilic particles anchored to the pore walls of the porous substrate, wherein a portion of the plurality of the hydrophilic particles have an anchored portion anchored to the pore walls and an exposed portion extending outwardly away from the pore wall upon which the anchored portion is anchored.
