Patent ID: 6976281

Claim:
A medical cushion ( 1 , 7 ), which is a multicellular anti-decubitus cushion, comprising a cushion which is equipped, where skin contact ( 6 , 13 ) occurs, with an active membrane ( 8 , 9 ) based on a skin-compatible matrix ( 4 , 10 ) into which a molecular sieve is mixed, said molecular sieve being charged with at least one active substance (Z, Z 1 , Z 2 , Z 3 , Z 4 ), and a molecular sieve/active substance adduct ( 5 , 11 , 12 ) releases the active substance when the active membrane comes into skin contact ( 6 , 13 ) in conjunction with the transpiration of the skin, and wherein the molecular sieve/active substance adduct ( 5 , 11 , 12 ) additionally contains crystallization water, such that the molecular sieve is partially dehydrated in relation to a sufficient base mol quantity (m) of crystallization water, and said molecular sieve containing the reduced mol quantity (m′) of crystallization water is charged with the active substance (Z, Z 1 , Z 2 , Z 3 , Z 4 ) such that, when the active membrane ( 3 , 9 ) comes into skin contact ( 6 , 13 ), adsorption of water takes place during desoroption of the active substance and the crystallization water content of the molecular sieve increases.
