Smart Inhaler Flow Sensor

Modern dry-powder inhalers embed a flow sensor that watches the patient's own breath do the work a propellant would otherwise do — deriving flow rate from the pressure drop across a fixed internal resistance and gating dose release on a minimum trigger flow. This simulator models that pipeline end to end: pick an inspiratory effort and a ramp time, choose a low, medium or high resistance device, and press Inhale to watch the sensor's Q = √ΔP / R equation play out as a live flow ramp in a real 3D device model. The resulting peak flow then drives a physically grounded split between turbulent powder deaggregation and inertial throat impaction, and you can watch the individual powder particles animate from the reservoir into either the throat, the lungs, or straight back out as exhaled, undeposited dose — with live sensor readouts for peak flow, lung deposition and oropharyngeal deposition updating on every breath.
