A METHOD AND A DEVICE FOR ESTIMATING AN AMOUNT OF A POWDER SHAPED MATERIAL PASSING A BEND IN A FLOW CHANNEL

The present invention provides a method for estimating an amount of a powder shaped material passing a bend in a flow channel, such as how much drug from an inhaler reaches the lungs of a person. The estimation is based on both the flow rate of the inhalation as well as the rate of release of the dr...

Beschreibung
Zusammenfassung:	The present invention provides a method for estimating an amount of a powder shaped material passing a bend in a flow channel, such as how much drug from an inhaler reaches the lungs of a person. The estimation is based on both the flow rate of the inhalation as well as the rate of release of the drug into the flow channel, where the rate or release itself depends on the flow.
