Device and method for monitoring thoracic and abdominal breathing patterns

A method for monitoring thoracic and abdominal breathing patterns, based on a device for monitoring thoracic and abdominal breathing patterns comprising a wearable vest internally covered with a layer of membrane pressure sensors, a micro control unit (MCU), and a liquid crystal display (LCD), wherein the MCU is connected to the membrane pressure sensors and the LCD separately;

• the membrane pressure sensors are disposed in chest, abdomen, and shoulder regions of the wearable vest, and configured to acquire pressure strain values generated by chest, abdomen, and shoulders of a wearer when the wearer is breathing and transmit the pressure strain values to the MCU;
• the MCU is configured to identify a breathing pattern of the wearer according to the pressure strain values;
• and the LCD is configured to display the pressure strain values generated by the chest, the abdomen, and the shoulders of the wearer and the breathing pattern of the wearer in real time three-dimensionally;
• the method comprising:
• receiving, by the MCU, the pressure strain values generated by the chest, the abdomen, and the shoulders of the wearer when the wearer is breathing and acquired by the membrane pressure sensors;
• calculating a thoracic breathing contribution ratio, an abdominal breathing contribution ratio, and a shoulder movement amplitude based on the pressure strain values;
• and
• identifying the breathing pattern of the wearer based on the thoracic breathing contribution ratio, the abdominal breathing contribution ratio, and the shoulder movement amplitude.
