Wearable multi-modal system for remote monitoring of patients with chronic obstructive pulmonary disease
A system of networked sensors designed to predict the onset of chronic obstructive pulmonary disease (COPD) symptoms is disclosed. The system is worn by an individual and the sensors collect data correlated with COPD symptoms. The collected sensor data is transmitted from the device to the user's mobile device for analysis. The results of the analysis may be forwarded to a health care provider.
1. A system for predicting onset and severity of Chronic Obstructive Pulmonary Disease (COPD) symptoms in a user comprising:
an apparatus wearable by the user having a housing with an exterior surface and an interior cavity, the apparatus including:
a battery disposed in the interior cavity and configured to provide electrical power;
a universal serial bus connection port;
one or more lights in electrical connection with the battery, wherein at least one of the one or more lights are visible from the exterior surface;
a power actuation switch accessible from the exterior surface, the power actuation switch in electrical connection with the battery;
a radio in electrical connection with the battery wherein the radio is configured to transmit sensor data over a wireless communications channel; and
sensors configured to generate the sensor data, the sensors including:
a digital microphone array in electrical connection with the battery,
a digital stethoscope in electrical connection with the battery,
an electrocardiogram sensor in electrical connection with the battery,
a thermometer in electrical connection with the battery, and
a goniometer in electrical connection with the battery,
wherein the sensor data comprises electrocardiogram data, user motion data, and user temperature data; and
a server configured to:
receive the sensor data;
apply a match filter to data from the user's left lung and right lung;
extract features from data from the user's left and right lungs to form feature data;
augment the feature data with additional data to form augmented data, the additional data comprising
user motion data, and
user temperature data;
generate a machine learning model, and
train the machine learning model using the augmented data;
wherein the machine learning model is configured to make a prediction on the
onset and severity of COPD symptoms in the user based on incoming sensor data.
2. The system of claim 1 , wherein the housing comprises connection points for one or more straps.
3. The system of claim 1 , further comprising a mobile device configured to receive the sensor data over the wireless communications channel and to forward the sensor data to the server over a second wireless communications channel.
4. The system of claim 1 , wherein the server is further configured to transmit the prediction to a medical provider.
5. The system of claim 1 , wherein the server is further configured to generate a questionnaire comprising one or more questions, automatically answer at least one of the questions based on the received sensor data, display the questionnaire to the user, the receive answers to at least one of the one or more questions from the user.
6. The system of claim 3 , wherein the mobile device further comprises a user interface configured to generate a digital avatar.
