Patent ID: 11083403

Abstract:
A pulmonary health assessment system for use with a handheld electronic device (HED) that includes a casing having a shape adapted to secure the HED with the casing. The casing includes a plurality of electrodes and a circuit board. The electrodes capture data indicative of the pulmonary health of the user. The circuit board includes a microphonic sensor, a diaphragm, a Photoplethysmography (PPG) sensor, an Inertial Measurement Unit (IMU) sensor, and a microcontroller. The microphonic sensor captures pulmonary audio signals indicative of the pulmonary health of the user. The diaphragm enhances the pulmonary audio signals. The PPG sensor measures pulmonary capillary blood flow. The IMU sensor captures seismic and auscultation signals indicative of the pulmonary health of the user. The microcontroller transmits pulmonary health data to the handheld electronic device and a computing device.
