CA 2527512

A drug delivery device (10) includes a pressurized reservoir (14) in communication with a flow path to an outlet (12). The flow path includes two normally-closed valves (16, 18) and a flow restriction (18). A pressure measurement arrangement (22) measures a differential fluid pressure between two points (24, 26) along the flow path which span at least part of the flow restriction (18), one of the points being between the valves (16, 18). A controller (28) selectively opens the valves (16, 18) to deliver a defined quantity of the liquid medicament to the outlet (12).

La présente invention concerne un dispositif d'administration de médicament (10) qui comprend un réservoir pressurisé (14) en communication avec une trajectoire d'écoulement menant à une sortie (12). La trajectoire d'écoulement comprend deux soupapes normalement fermées (16, 20) et un étranglement de débit (18). Un mécanisme de mesure de pression (22) mesure une pression de liquide différentielle entre deux points (24, 26) sur la trajectoire d'écoulement couvrant au moins une partie de l'étranglement de débit (18), l'un des points étant situé entre les soupapes (16, 20). Un contrôleur (28) ouvre sélectivement les soupapes (16, 20) pour libérer une quantité définie du médicament liquide jusqu'à la sortie (12).
