Pulmonary health management device

An inhalation device comprising:

• a housing including a mouthpiece and defining an air flow channel;
• a piezoelectric driven ejector assembly positioned in fluid communication with the air flow channel and configured to eject droplets of a fluid into the air flow channel;
• a pressure sensor assembly configured to measure air flow within the air flow channel;
• a controller electrically coupled to the piezoelectric driven ejector assembly and the pressure sensor assembly;
• and a memory storing instructions executable by the controller to:
• (i) determine, during a user initialization phase comprising a set number of deep breaths taken on the device, a trigger point during user initialization inhalation;
• (ii) actuate the piezoelectric driven ejector to dispense a dose of the fluid when the trigger point is reached during a dosing inhalation by the user;
• and
• (iii) generate pulmonary health management information including a pulmonary health profile based on (a) a peak inspiratory flow measurement generated from a minimum pressure measured during inhalation and (b) a pulmonary output determined by measuring a maximum flow achieved during exhalation.
