ASTHMA DIAGNOSIS AND MANAGEMENT SYSTEM
An asthma diagnosis and management system including a valved holding chamber defining an interior cavity, a backpiece having an opening configured to receive a pressurized metered dose inhaler and a user interface. A microphone is coupled to the valved holding chamber and is in communication with an interior of the valved holding chamber and is configured to capture a sound of a user's lungs.
1 . An asthma diagnosis and management system comprising:
a valved holding chamber defining an interior cavity, a backpiece having an opening configured to receive a pressurized metered dose inhaler and a user interface; and
a microphone coupled to the valved holding chamber and in communication with an interior of the valved holding chamber, wherein the microphone is configured to capture a sound of a user's lungs.
2 . The asthma diagnosis and management system of claim 1 wherein the microphone is attached to the backpiece.
3 . The asthma diagnosis and management system of claim 2 wherein the valved holding chamber comprises a valve assembly longitudinally spaced from the backpiece, wherein the microphone faces the valve assembly.
4 . The asthma diagnosis and management system of claim 3 wherein the microphone comprises an ECM microphone.
5 . The asthma diagnosis and management system of claim 1 wherein the valved holding chamber comprises a valve assembly longitudinally spaced from the backpiece, wherein the microphone is coupled to the valve assembly.
6 . The asthma diagnosis and management system of claim 5 wherein the valve assembly comprises a baffle, wherein the microphone is coupled to the baffle.
7 . The asthma diagnosis and management system of claim 1 wherein the microphone is releasably coupled to the valved holding chamber.
8 . The asthma diagnosis and management system of claim 1 further comprising a protective element covering the microphone.
9 . The asthma diagnosis and management system of claim 1 further comprising a sound emitting device coupled to the valved holding chamber and disposed adjacent the microphone, wherein the sound emitting device is configured to emit a sound for calibration of the microphone.
10 . The asthma diagnosis and management system of claim 1 further comprising at least one secondary microphone coupled to the valved holding chamber.
11 . The asthma diagnosis and management system of claim 10 wherein the secondary microphone is in communication with an exterior ambient environment of the valved holding chamber.
12 . The asthma diagnosis and management system of claim 1 further comprising an ambient lung sound breath lung recording device comprising a microphone and configured to autonomously and actively record respiratory sounds, wherein the ambient lung sound breath lung recording device may be paired with the valved holding chamber.
13 . An asthma diagnosis and management system comprising:
a valved holding chamber defining an interior cavity, a backpiece having an opening configured to receive a pressurized metered dose inhaler and a user interface; and
an electronic stethoscope coupled to the smart valved holding chamber and configured to capture a sound of a user's lungs.
14 . A method of diagnosing and managing a user's asthma comprising:
actuating a pressurized metered dose inhaler coupled to a backpiece of a valved holding chamber;
inhaling through a user interface component of the valved holding chamber;
capturing a sound of the user's lungs while inhaling with a microphone in communication with an interior of the valved holding chamber;
waiting a predetermined period of time; and
breathing through the valved holding chamber without actuating the pressurized dose inhaler after the predetermined period of time and capturing a second sound of the user's lungs while breathing through the valved holding chamber.
