Title (EN) AUGMENTED PRESSURE THERAPY FOR WOUNDS
(FR) TRAITEMENT DES PLAIES PAR PRESSION AUGMENTÉE
Abstract:
(EN) The apparatus for wound therapy disclosed herein may include a wound interface that sealingly defines a fluid-tight enclosed space surrounding a wound bed. The pressure p0 within the enclosed space may be varied periodically in a pressure cycle between a minimum pressure pmin and a maximum pressure pmax where pminpambpmax, the pressure pamb being the ambient pressure, by consecutive withdrawal of fluid from the enclosed space and input of fluid into the enclosed space through a port of the wound interface. The enclosed space may be evacuated to a pressure pmin less than ambient pressure pamb and a condition of essentially no fluid passing through the enclosed space. The fluid communicated into the enclosed space may be either a liquid or a gas having an O2 concentration greater than atmospheric air.
(FR) La présente invention concerne un appareil de traitement des plaies pouvant comprendre une interface de plaie qui définit de façon étanche un espace fermé étanche aux fluides entourant un lit de plaie. La pression p0 à l'intérieur de l'espace fermé peut être modifiée périodiquement dans un cycle de pression entre une pression minimale pmin et une pression maximale pmaxpminpambpmax, la pression pamb étant la pression ambiante, par retrait consécutif de fluide de l'espace fermé et entrée de fluide dans l'espace fermé par l'intermédiaire d'un orifice de l'interface de plaie. L'espace fermé peut être évacué pour atteindre une pression pmin inférieure à la pression ambiante pamb et une condition dans laquelle sensiblement aucun fluide ne traverse l'espace fermé. Le fluide communiqué dans l'espace fermé peut être soit un liquide soit un gaz ayant une concentration en O2 supérieure à celle de l'air atmosphérique.
