Title
(EN) LIQUID CLEANING AND STERILIZATION SYSTEM AND METHOD
(FR) SYSTEME ET PROCEDE DE NETTOYAGE ET DE STERILISATION PAR DES LIQUIDES
Abstract
(EN) A fluid delivery system (26) for an automated processor (A) delivers washing, microbial decontaminant, and rinse fluids to spray nozzles (102, 104, 106, 108, 110) in a chamber (12) for sequentially spraying the fluids over a lumened device (B), such as a n endoscope. The fluid delivery system also delivers the fluids to connection ports (150, 152, 154) which connect with internal passages (187) of the device for delivering the fluids thereto. Leaking connectors (184) connect the automated processor connection ports with inlet ports (196) of the device and allow a portion of the washing, decontaminant, and rinsing solutions to leak from each inlet port. The endoscope is supported on a rack which is agitated by an activation system (330). A computer control system (80) controls cleaning, decontamination, rinsing, and drying stages of a cycle, which are all carried out within the chamber, obviating the need for human contact with the device during processing. A door locking and latching mechanism (90) ensures that the door remains locked during the washing, decontamination, and rinse cycle to avoid accidental injury to an operator from strong chemicals used in the system.
(FR) L'invention concerne un système (26) d'apport de fluides pour processeur (A) automatisé, qui fournit des fluides de lavage, de décontamination microbienne et de rinçage à des buses (102, 104, 106, 108, 110) de pulvérisation situées dans une chambre (12) en vue de pulvériser les fluides sur un dispositif (B) comportant des lumières, tel qu'un endoscope. Le système d'apport de fluides amène aussi les fluides vers des orifices (150, 152, 154) de connexion reliés à des passages (187) internes du dispositif pour permettre un apport de fluides vers ceux-ci. Des connecteurs (184) d'écoulement relient les orifices de connexion du processeur automatisé à des orifices (196) d'entrée du dispositif, et permettent à une partie des solutions de lavage, de décontamination et de rinçage de s'écouler hors de chaque orifice d'entrée. L'endoscope repose sur un support qui est agité par un système d'activation (330). Un système (80) de commande informatique commande les étapes de nettoyage, de décontamination, de rinçage et de séchage d'un cycle, qui sont toutes mises en oeuvre dans la chambre afin d'éviter tout contact humain avec le dispositif pendant le traitement. Un mécanisme (90) de serrure et de verrou de porte permet d'assurer que la reste verrouillée pendant le cycle de lavage, de décontamination et de rinçage afin d'éviter à un opérateur de se blesser accidentellement avec les produits chimiques concentrés utilisés dans le système.
