Embodiment Construction
[0034] The present disclosure describes devices, systems and methods for sensing, tracking and / or processing usage conditions and parameters associated with drug delivery devices. These devices, systems and methods are described in the context of a breath-actuated inhalation device for delivering medicament to the lungs of a user. However, the described technical solutions are equally applicable to other drug delivery devices, such as syringes, metered dose inhalers, nebulizers, transdermal patches or implantable devices.
[0035] Asthma and COPD are chronic inflammatory diseases of the airways. They are all characterized by variable and recurring symptoms of airflow obstruction and bronchospasm. Symptoms include wheezing, coughing, chest tightness, and shortness of breath. Manage symptoms by avoiding triggers and by using medications, especially inhaled ones. Medications include inhaled corticosteroids (ICS) and bronchodilators.
[0036] Inhaled corticosteroids (ICS) are ...

A system may include an external device and an inhaler. The external device may include a processor, a communication circuit, and memory. The inhaler may include a mouthpiece, medicament, a mechanical dose counter, and an electronics module comprising a processor and a communication circuit. The electronics module may record a dosing event when the inhaler is actuated, such as when the mouthpiece cover is opened, and send a signal indicating the dosing event to the external device. The external device may receive a mechanical dose reading of the mechanical dose counter, determine an electronic dose reading based on the signal indicating the dosing event, determine that a discrepancy between the mechanical dose reading and the electronic dose reading exceeds a threshold, and notify the user of the discrepancy, for example, by providing a notification to the user by way of a mobile application residing on the external device.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 849,552, filed May 17, 2019, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Drug delivery devices facilitate the delivery of drugs into patients via various routes of administration. Typical routes of administration include oral, topical, sublingual inhalation, injection, and the like. The device can be used to deliver drugs to treat various diseases, ailments and medical conditions. For example, inhalation devices may be used to treat asthma, chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF). Although drug delivery devices are designed to deliver appropriate doses of drugs to patients as part of therapy, the effectiveness of a particular therapy can be affected by nonphysiological factors, such as patient persistence and compliance. [0004] In the context o...
