A safety interlock system (11) for a flow control apparatus (12) is disclosed that permits operation when a magnet-less administration feeding set (14) is properly mounted to recess (29) formed along the housing (20) of the flow control apparatus (12). The administration feeding set (14) comprises flexible patient tubing having a support member (18) at one end and a mounting member (30) including a magnetically-susceptible metallic component (21) at the other end thereof. A sensing arrangement (33)is provided by the flow control apparatus (12) for sensing the proper engagement of the metallic component (21) to the recess (29) of the flow control apparatus (12). A control means (40) permits operation of the flow control apparatus (12) when the metallic member (21) is properly engaged to recess (29), while terminating operation when the metallic member (21) is improperly engaged to recess (29).

L'invention concerne un système de verrouillage de sécurité (11) destiné à un dispositif de commande de flux (12), pouvant fonctionner lorsqu'un ensemble d'alimentation d'administration sans aimant (14) est monté correctement sur une cavité (29) formée le long du boîtier (20) du dispositif de commande de flux (12). L'ensemble d'alimentation d'administration (14) comporte une tubulure flexible présentant un élément support (18) sur une extrémité et un élément de montage (30) pourvu d'un composant métallique magnétique (21), sur l'autre extrémité. Ledit dispositif de commande de flux (12) comporte un système de détection (33) destiné à détecter l'encastrement correct du composant métallique (21) dans la cavité (29) dudit dispositif de commande de flux (12). Un élément de commande (40) permet le fonctionnement du dispositif de commande de flux (12) lorsque l'élément métallique (21) est correctement encastré dans la cavité (29), et interrompt son fonctionnement lorsque l'élément métallique (21) est mal encastré dans la cavité (29).
