Patent abstract
A vein thromboembolism (VTE) risk assessment system that includes a casing having a shape adapted to secure a plurality of components with the casing. The casing includes a microphonic sensor, a Photoplethysmography (PPG) sensor, an Inertial Measurement Unit (IMU) sensor, a diaphragm, and a microcontroller. The microphonic sensor captures VTE audio signals indicative of the VTE risk of the user. The PPG sensor measures blood volume changes in a skin area in response to venous hemodynamic changes in a lower limb. The IMU sensor captures seismic signals indicative of the VTE risk of the user. The diaphragm enhances auscultation signals. The microcontroller transmits data to a computing device.
