Title (EN) VACUUM ASSISTED TISSUE TREATMENT SYSTEM
(FR) SYSTEME DE TRAITEMENT DE TISSU A DEPRESSION
Abstract:
(EN) A system (10) for stimulating the healing of tissue comprises a porous pad (11) positioned within a wound cavity (12), and an airtight dressing (13) secured over the pad, so as to provide an airtight seal to the wound cavity (12). A proximal end (16a) of a conduit (16) is connectable to the dressing (13). A distal end (16b) of the conduit (16) is connectable to a negative pressure source (14), which may be an electric pump housed within a portable housing (32), or wall suction. A canister (18) is positioned along the conduit (16) to retain exudates suctioned from the wound site (12) during the application of negative pressure. A first hydrophobic filter (20) is positioned at an opening of the canister (18) to detect a canister full condition. A second hydrophobic filter (22) is positioned between the first filter (20) and the negative pressure source (14) to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter (23) is positioned between the first and second hydrophobic filters (20, 22) to aid in the reduction of malodorous vapors. A securing means (34) is supplied to allow the portable housing (32) to be secured to a stationary object, such as a bed rail or intravenous fluid support pole. A means for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A means for varying pump drive frequency and a means for managing a portable power supply are provided to increase battery life and improve patient mobility.
(FR) L'invention concerne un système (10) destiné à accélérer la cicatrisation du tissu et comprenant un tampon poreux (11) introduit dans une plaie (12) ainsi qu'un pansement étanche à l'air (13) fixé sur ce tampon, d'où l'obtention d'une fermeture hermétique sur la plaie (12). Une extrémité proximale (16a) d'un conduit (16) peut être raccordée au pansement (13), une extrémité distale (16b) de ce conduit (16) pouvant être raccordée à une source de dépression (14), telle qu'une pompe électrique logée dans un boîtier portatif (32), ou à une prise murale de vide. Un collecteur (18) installé sur le conduit (16) permet de retenir les exsudats aspirés à partir de la plaie (12) pendant l'application d'une dépression. Un premier filtre hydrophobe (20) disposé au niveau d'une ouverture du collecteur (18) permet de détecter si ce dernier est rempli. Un second filtre hydrophobe (22) installé entre le premier filtre (20) et la source de dépression (14) empêche une contamination de la partie non jetable du système par les exsudats extraits de la plaie. Un filtre à odeur (23) disposé entre lesdits premier et second filtres hydrophobes (20, 22) permet de réduire les vapeurs malodorantes. Un organe de fixation (34) sert à fixer le boîtier portatif (32) sur un objet fixe, tel qu'un côté de lit ou un support pour intraveineuse. On utilise une unité faisant osciller automatiquement la pression au fil du temps en vue d'améliorer et d'accélérer la cicatrisation d'une plaie ouverte. Une unité faisant varier la fréquence d'entraînement de la pompe ainsi qu'une unité de gestion d'alimentation portative permettent d'augmenter la durée de vie de la batterie et d'améliorer la mobilité du patient.
