The device comprises a dressing made from a porous material (11) intended for placing against tissues, for example skin, the material being synthetic or organic and being distinguished by communicating cavities in the form of open pores, interdigitating gaps in particle material or communicating cavities in capillary structures. The dressing (11) can, by layers, have different cavity qualities and is provided with a dense, sealing shell (10) or layer in which is disposed at least one fluid supply connection (12) and at least one fluid removal connection (13) in spaced apart relationship. Conduits are coupled to the connections (12, 13) and permit the establishment of treatment fluid flow from the supply connection (12), through the cell material dressing (11) in contact with the tissue, to the removal connection (13). Fluid supply can be effected under pressure and/or fluid removal under suction. Electrodes can be disposed in the cell material dressing (11) for sensing the fluid saturation degree, and with the possibility of registering and/or regulating this saturation degree by means of valves. Temperature sensors may be provided in the supply conduit or in the cell material dressing (11) and may be connected to a temperature regulator. Fluid-impervious walls may be provided in the cell material dressing (11) for guiding the treatment fluid flow. The cell material dressing may have one or several replaceable layers.

1. A device for treatment of tissue, comprising: a dressing formed of a porous material having first and second opposed major surfaces; said first major surface being exposed; a fluid supply pipe delivering fluid supplied thereto directly to only a first portion of said dressing; a fluid removal pipe directly receiving fluid exiting said dressing at a second portion of said dressing only, said second portion being spaced from said first portion; the internal structure of said dressing causing fluid entering said fluid supply pipe to migrate from said first portion to said second portion of said dressing as a result of the capillary action of said porous material. 2. A device according to claim 1, wherein said first and second portions are at opposite ends of said dressing. 3. A device according to claim 2, wherein said first and second major opposed surfaces are substantially planar and parallel to each other and wherein said fluid migrates in a direction substantially parallel to said surfaces. 4. A device according to any one of claims 1, 2 or 3, further including means for introducing fluid into said fluid supply pipe under pressure. 5. A device according to any one of claims 1, 2 or 3, further including means for removing fluid from said fluid removal pipe by suction. 6. A device according to any one of claims 1, 2 or 3, further including means for sensing the degree of fluid saturation in said dressing. 7. A device according to claim 6, wherein said means includes electrodes disposed in said dressing. 8. A device according to claim 6, further including means for registering said second degree of fluid saturation. 9. A device according to claim 6, further including means for regulating the flow of fluid through said dressing as a function of said sensed degree of fluid saturation. 10. A device according to any one of claims 1, 2 or 3, wherein said dressing includes fluid impervious walls for guiding the flow of fluid between said fluid supply pipe and said fluid removal pipe. 11. A device according to claim 1, wherein said dressing includes a replaceable micropore layer defining said first major surface. 12. A device according to claim 1, wherein said dressing comprises at least one cellular material having open pores. 13. A device according to claim 1, wherein when said exposed major surface of said dressing is placed against injured tissue, said dressing influences said injured tissue by sorptive processes. 14. A device according to claim 1, further including means for supplying fluid to said fluid supply pipe and temperature regulating means for regulating the temperature of said fluid before it is supplied to said fluid supply pipe. 15. A device according to claim 14, wherein said temperature regulating means includes sensors disposed in said dressing. 16. A device according to any one of claims 1, 2 or 3, wherein the internal structure of said dressing causes said fluid to distribute through substantially the entire area of said dressing due to capillary action. 17. A device according to claim 1, further including a fluid impervious layer located on said second major surface. 18. A device according to claim 17, wherein said fluid supply pipe includes a first opening formed in said fluid impervious layer and said fluid removal pipe includes a second opening, spaced from said first opening, formed in said fluid impervious layer.
