Dressing assemblies for wound treatment using reduced pressure

摘要

A dressing assembly (30) for use with a reduced pressure treatment system, the dressing assembly develops a directed force under reduced pressure. The directed force may be a radial force or a closing force. The dressing assembly includes a shaped dressing bolster (32) having a shaped extremity that is operable to evenly deliver the radial force and to distribute reduced pressure. Numerous shapes may be used for the shaped extremity. The dressing assembly may further include an over-drape (62) to assist in creating a seal over the shaped dressing bolster and against a portion of a patient's epidermis.
