Abstract
An inhalation system including a metered dose inhaler and a separate computing device. The inhaler includes a flow rate sensor for detecting an inhalation flow through the actuator housing upon patient inhalation and a transmitting unit for transmitting a signal of the at least first switch as well as of the flow rate sensor to the computing device. The computing device generates visual and/or acoustic messages independently of the signals of the at least one switch and the flow rate sensor in order to guide the patient through multiple steps. The computing device further evaluates the use of the inhaler by comparing the transmitted signals of the at least first switch and of the flow rate sensor with the visual and/or acoustic messages. The transmitting unit transmits the signals of the at least first switch and the flow rate sensor to the computing device after the use of the inhaler.
