System and method for controlling inhaler dosage

An inhaler based data collection system, the system comprising:

• a physiological sensor configured to be coupled to a user to sense physiological data from the user at a first base sampling rate;
• an inhaler mateable with a drug container, the inhaler including a dosing mechanism operable to aerate a dose from the drug container, the dosing mechanism providing the aerated dose to the user, the aerated dose configured to stimulate a physiological response of deepening a breath shape and slowing a breath rate of the user;
• a sensor interface coupled to the physiological sensor to sense a response to the dose;
• a controller coupled to the sensor interface to increase the sample rate of the physiological sensor from the first base sampling rate to a second sampling rate for a predetermined period of time to collect physiological data from the user corresponding to the predetermined period of time after a time that the aerated dose is delivered to the user, and a transceiver;
• a data server to receive the collected physiological data from the transceiver;
• and
• an analysis module operable to determine an effectiveness of the dose based on the collected physiological data in deepening breath shape and slowing breath rate based on determining whether a plurality of breath shapes of the physiological data taken in the predetermined period of time is within range of a baseline physiological response of a deeper breath shape and a slower breath rate.

A dosage control unit for installation on an inhaler, the inhaler having an actuator holding a drug container containing a drug, a dosing mechanism coupled to the drug container to aerate a dose from the drug container, the dosing mechanism providing the aerated dose to a user, the dosage control unit comprising:

• an interface attaching the dosage control unit to the inhaler;
• a dosing sensor configured to detect the dosing mechanism aerating the dose, the aerated dose configured to stimulate a physiological response of deepening a breath shape and slowing a breath rate of the user;
• a sensor interface configured to be in communication with a physiological sensor configured to be attached to the user of the inhaler, wherein the physiological sensor is configured to sense physiological data from the user at a first base sampling rate;
• and
• a controller coupled to the dosing sensor and the sensor interface, the controller operable to increase the sample rate of the physiological sensor from the first base sampling rate to a second sampling rate for a predetermined period of time to collect physiological data from the user corresponding to the predetermined period of time after a time that the aerated dose is delivered to the user, wherein the time that the aerated dose is delivered is determined from the dosing sensor, and wherein the controller is operable to determine an effectiveness of the dose in deepening breath shape and slowing breath rate based on determining whether a plurality of breath shapes of the physiological data taken in the predetermined period of time is within range of a baseline physiological response of a deeper breath shape and a slower breath rate.
