Abstract

Nouveaux procédé et système pour le traitement du sang et d'autres fluides organiques depuis un donneur jusqu'à un récipient ou un réceptacle de stockage ou dans un système de recyclage utilisant de nouvelles cuves de traitement électriquement conductrices pour le traitement du sang ou d'autres fluides organiques avec des forces de champ électrique d'une intensité appropriée pour assurer un flux de courant électrique à travers le sang ou d'autres fluides organiques. Ledit courant électrique doit être d'une intensité biologiquement compatible, mais suffisante pour rendre les bactéries, les virus, et/ou les champignons inopérants afin qu'ils ne puissent pas infecter des cellules normalement saines; l'intensité du courant doit en outre permettre de conserver l'utilité biologique du sang et d'autres fluides organiques. A cette fin, les potentiels électriques de faible tension appliqués à la cuve de traitement devraient être compris entre environ 0,2 et 12 volts et devraient produire des densités de flux de courant comprises entre un microampère par millimètre carré de la zone d'électrode en contact avec le fluide traité jusqu'à environ un milliampère par millimètre carré. La durée de traitement dans cet ordre de paramètres peut aller d'environ une minute jusqu'à environ 12 minutes.
