(EN) SYSTEMS AND METHODS FOR ONSITE SORBENT MATERIAL REUSE
(FR) SYSTÈMES ET PROCÉDÉS DE RÉUTILISATION DE MATÉRIAU SORBANT SUR SITE
Abstract
(EN)
Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H+ZP within a casing for a treatment; and after the treatment, refurbishing the H+ZP while maintained within the casing via (i) regenerating the non-disinfected H+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H+ZP while maintained within the casing. Multiple batch sorbent refubishing implementations are also disclosed.

L'invention concerne des procédés, des cartouches de sorbant et des dispositifs de nettoyage pour la remise en état de matériaux sorbants. Dans un mode de réalisation parmi de multiples modes de réalisation, un procédé de distribution de fluide médical comprend les étapes consistant à: placer une cartouche de sorbant comprenant du H+ZP à l'intérieur d'un boîtier pour effectuer un traitement; et après le traitement, remettre en état le H+ZP tandis qu'il est maintenu à l'intérieur du boîtier par l'intermédiaire (i) d'une régénération du H+ZP non désinfecté par l'écoulement d'une solution acide à travers le boîtier, (ii) du rinçage du H+ZP régénéré tandis qu'il se trouve dans le boîtier, (iii) de la désinfection du H+ZP régénéré et rincé par écoulement d'un agent désinfectant à travers le boîtier, et (iv) du rinçage du H+ZP régénéré et désinfecté tandis qu'il se trouve dans le boîtier. L'invention concerne également de multiples mises en oeuvre de remise en état de sorbant par lots multiples.
