Title (EN) FLOW DETECTOR
(FR) DÉBITMÈTRE
Abstract:
(EN) Disclosed is a flow detector (1) for releasable coupling with a flow channel ( 20) in a channel coupling area and detecting a flow of liquid drug in the flow channel (20), the flow detector including: ∙ an upstream thermoelectric element (10a) and a downstream thermoelectric element (10b), wherein the upstream thermoelectric element (10a) and the downstream thermoelectric element ( 1 0b) are arranged spaced apart from each other and movable independent from each other; ∙ an upstream biasing element (15a) and a downstream biasing element (15b), wherein the upstream biasing elements (15a) acts on the upstream thermoelectric element (10a), thereby biasing the upstream thermoelectric element (10a) towards the channel coupling area, and the downstream biasing element (15b) acts on the downstream thermoelectric element (10b), thereby biasing the downstream thermoelectric element (10b) towards the channel coupling area independently from the upstream biasing element (15a).
(FR) La présente invention concerne un débitmètre (1) couplé de façon amovible avec un canal d'écoulement (20) dans une zone de couplage de canal et la détection d'un débit de médicament liquide dans le canal d'écoulement (20), le débitmètre comprenant : ∙ un élément thermoélectrique en amont (10a) et un élément thermoélectrique en aval (10b), l'élément thermoélectrique en amont (10a) et l'élément thermoélectrique en aval (10b) sont espacés l'un de l'autre et mobiles indépendamment l'un de l'autre; ∙ un élément de sollicitation en amont (15a) et un élément de sollicitation en aval (15b), où l'élément de sollicitation en amont (15a) agit sur l'élément thermoélectrique en amont (10a), sollicitant ainsi l'élément thermoélectrique en amont (10a) en direction de la zone de couplage de canal, et l'élément de polarisation en aval (15b) agit sur l'élément thermoélectrique en aval (10b), sollicitant ainsi l'élément thermoélectrique en aval (10b) vers la zone de couplage de canal indépendamment de l'élément de polarisation en amont (15a).
