Mobile front-end system for comprehensive cardiac diagnosis

摘要

A stethoscope front-end recorder device (also referred to as Sleeve) for the chest piece of a stethoscope, which is easily installed and removed. The Sleeve is attached to the chest piece of a stethoscope for comprehensive diagnosis of heart issues. The Sleeve contains sensors for acquiring biosensor parameters such as electrocardiogram, body temperature, heartbeat, heart rhythm, heart rate variability, heart rate turbulence, heart sounds, respiration, cardiac index and blood flow. The Sleeve has Bluetooth interface communicating with a mobile device with software component, interfacing with a back-end server with the capability to capture, analyze and save patient information.
