Absorbent body consisting of a fluid-absorbing substance (1) which is enclosed in a jacket (2,5), and outside the jacket a fluid-absorbing layer (3), e.g. cellulose wadding, at least on the portion of the jacket intended to face the fluid-discharging region, and possibly outside this layer a wound-p

Absorbent body consisting of a fluid-absorbing substance (1) which is enclosed in a jacket (2,5), and outside the jacket a fluid-absorbing layer (3), e.g. cellulose wadding, at least on the portion of the jacket intended to face the fluid-discharging region, and possibly outside this layer a wound-protecting layer (4), at least a portion (2) of the jacket, which is in contact with the absorbent layer (3), being made of a semipermeable membrane film which is permeable to the fluid discharged from the fluid-discharging region but which is not permeable to the fluid-absorbing substance, the remainder of said jacket (5) consisting of a liquid-tight material.

An absorbent body for absorbing a fluid from a fluid-discharging region, comprising: an absorbent layer adapted to absorb said fluid; a jacket which is positioned immediately to contact with said absorbent layer, at least a portion of the jacket which is facing said absorbent layer been made of a micro-porous semi-permeable membrane film, which is permeable to said fluid discharged from said fluid-discharging region and absorbed by said absorbent layer, the remainder of said jacket being made of a liquid-tight material; a fluid absorbent substance causing osmotic activity being enclosed in said jacket and adapted to absorb said fluid, said membrane film being non-permeable to said fluid-absorbing substance; said semi-permeable membrane being liquid-tight when the osmotic pressure differential across said membrane is zero and being permeable to said fluid due to an osmotic pressure differential across said membrane.
