Title:
DRUG DELIVERY DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO2004105827
Kind Code:
A3
Abstract:
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).
