Systems and methods for removing a contaminant from a fluid like blood, regardless of whether the contaminant is carried free within the fluid or entrained within cellular matter carried within the fluid. The systems and methods rely upon photodynamic processes to remove free contaminants from the fluid. The systems and methods rely upon separation processes to remove the cellular matter and, with it, the contaminants it entrains from the fluid. The system (10) includes a treatment device (12) that receives the fluid from a source container (14) and conveys the fluid after treatment to a collection container (16). Treatment device (12) includes housing (18) that encloses an interior chamber (20) which has an inlet (22) for receiving a blood suspension from source container (14) and an outlet (24) for discharging the blood suspension. Device (12) also comprises first element (26) for separating cellular components from the blood, and second element (28) which employs photodynamic therapy to remove the free biological contaminants.
Systèmes et procédés d'élimination d'un contaminant dans un fluide tel que le sang, que le contaminant soit porté libre dans le fluide ou entraîné à l'intérieur de matières cellulaires portées par le fluide. Les systèmes et procédés utilisent des processus photodynamiques pour enlever du fluide les contaminants libres, et des processus de séparation pour enlever les matières cellulaires entraînant des contaminants. Ledit système (10) comprend un dispositif de traitement (12) recevant le fluide provenant d'un récipient d'alimentation (14), et envoyant le fluide traité vers un récipient collecteur (16). Ledit dispositif de traitement (12) comporte un boîtier (18) doté d'une chambre intérieure (20) possédant un conduit d'entrée (22) pour une suspension sanguine provenant du récipient d'alimentation (14), ainsi qu'un conduit de sortie (24) permettant la décharge de ladite suspension sanguine. Ledit dispositif (12) comporte également un premier élément (26) de séparation des constituants cellulaires du sang, et un second élément (28) employant la thérapie photodynamique pour éliminer les contaminants biologiques libres.
