Title (EN) DOSING SAFETY ARRANGEMENT IN A DELIVERY APPARATUS FOR PRESSURISED MEDICAL LIQUIDS
(FR) DISPOSITIF DE SECURITE DE DOSAGE DANS UN APPAREIL DE DISTRIBUTION DE LIQUIDES MEDICAUX SOUS PRESSION
Abstract:
(EN) A delivery apparatus for pressurised medical liquids comprising: a primary reservoir (1) configured for pressurising medical liquid (2) in the primary reservoir to a driving pressure; a secondary reservoir (22) having an inlet connected to receive pressurised liquid from the primary reservoir (1) via a controllable intermediate valve (8), and an outlet (25) for egress of the received medical liquid via a controllable dosing valve (26); a pressure measuring means (30) configured to measure the pressure in the secondary reservoir (22); and a control unit (40) configured to control the intermediate valve (8) and the dosing valve (26), wherein the control unit (40) is configured to monitor the function of the intermediate valve (8) and the dosing valve (26) dependent on measured pressure values from the pressure measuring means (30) and to generate a status signal dependent on predetermined rules for measured pressure changes compared with calculated pressure changes.
(FR) L'invention concerne un appareil de distribution de liquides médicaux sous pression comprenant un premier réservoir (1) configuré pour mettre sous pression un liquide médical (2) selon une pression de commande; un second réservoir (22) présentant une entrée connectée destinée à recevoir un liquide sous pression du premier réservoir (1) au moyen d'une valve intermédiaire réglable (8), et une sortie (25) pour le liquide médical reçu au moyen d'une valve de dosage réglable; un moyen (30) de mesure de la pression configuré pour mesurer la pression dans le second réservoir (22); et une unité de commande (40) configurée pour commande la valve intermédiaire (8) et la valve (8) de dosage, l'unité (40) de commande étant configurée pour contrôler la fonction de la valve intermédiaire (8) et de la valve (26) de dosage en fonction des valeurs de pression mesurées par le moyen (30) de mesure de pression, et pour générer un signal d'état en fonction de règles prédéterminées des changements de pression mesurés par rapport aux changements de pression calculés.
