Abstract

L'invention concerne un dispositif de retraitement d'endoscope 1 comprenant : un réservoir de traitement 21 ; une section contenant un liquide chimique 101 ; une buse de liquide chimique 111 ayant à son extrémité avant une ouverture de décharge 112 ouverte vers le réservoir de traitement 21 ; une pompe 121 ; un premier conduit 131 ayant une première section d'étanchéité à l'eau Ws1 et reliant la section contenant un liquide chimique 101 et la pompe 121 ; un deuxième conduit 141 ayant une seconde section d'étanchéité à l'eau Ws2 et reliant la pompe 121 et la buse de liquide chimique 111 ; un troisième conduit 151 pour relier la deuxième conduite 141 et la première conduite 131 ou la section contenant un liquide chimique 101 et la première section d'étanchéité à l'eau Ws1 et la seconde section d'étanchéité à l'eau Ws2 ; et une section de résistance à la vitesse d'écoulement pour réduire la vitesse d'écoulement à travers le troisième conduit jusqu'à un niveau inférieur à celui de la vitesse d'écoulement à travers le second conduit.
