Abstract
(EN)
An anisotropic wound drape (116) for treating a wound on a patient includes a flexible sheet (123) for placing over a tissue site. The flexible sheet includes a first isotropic zone (124), and a second isotropic zone (126). The first isotropic zone and the second isotropic zone are configured to provide the flexible sheet with anisotropic stretching properties. The anisotropic drape (116) may used as part of a reduced-pressure wound treatment system. Other systems and methods are also presented.

L'invention concerne un drapage de blessure anisotrope (116) destiné à traiter une blessure chez un patient. Le drapage selon l'invention comprend une feuille flexible (123) destinée à être placée sur un site de tissu. La feuille flexible comprend une première zone isotrope (124) et une seconde zone isotrope (126). La première zone isotrope et la seconde zone isotrope sont configurées pour conférer des propriétés d'étirement anisotropes à la feuille flexible. Le drapage anisotrope (116) peut être utilisé dans le cadre d'un système de traitement des blessures à pression réduite. D'autres systèmes et procédés sont également présentés.
