摘要：
The present disclosure relates to a device (10) and method for measuring theresistance of inhalers (20) to air flow.In particular, the device and method can be used to measure the resistance toair flow of dry powder inhalers (20), which are usedfor pulmonary drug delivery. The device (10) has a pair of chambers (12, 18)to mount and enclose an inhaler (20) within. Eachchamber (12, 18) has a respective valve. The device (10) has further apressure controller (22), a flow controller (24) and pressureand flow sensors and microprocessors configured to control opening and closingof the valves and to detect and analyze the correspondingsignals.
