20110313377REDUCED PRESSURE THERAPY DEVICES - Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.12-22-2011

The liquid-permeable envelope has pores, the size of which does not exceed that of the super-absorbing particles. The absorption body, inserted in the wound space, has an initial volume, which enlarges in the course of the absorption process, and a final volume, so that, due to the size of the pores of the envelope, the absorbed wound secretions remain within the absorption body and, with that, below the wound-covering element, until the absorption body is removed from the wound space.12-22-2011
