The medical stethoscope is already very familiar to doctors, medical staff and people. However, when used for a long time, it will be very painful to the ears, cannot be used in a loud noise environment. So we started our project to make a smart medical stethoscope which is much more comfortable for doctors and medical staffs. Our smart medical stethoscope is made by 01 max9821 module (microphone amplifier), 01 xh-m802 module (frequency filter), 01 XPT8871 module (audio amplification), 01 Arduino Micro kit (smart processing) and 01 0.96 inch OLED screen. The entire circuit is powered by a 3.7V - 2000 mAh Lithium battery. The stethoscope uses the vibrating diaphragm of a traditional stethoscope and is converted into an electrical signal by the max9821 and tuned to the desired sound frequency by the xh-m802 then amplified by the XPT8871 and delivered to the user's ear by a high-quality headset. Moreover, the audio signal is sent to the Arduino Micro for analysis, displaying on the Oled screen the heart rate index and diagnostic suggestions for the patient's condition. Our equipment can replace all traditional stethoscopes with the same usage. But the advantage here is that it is comfortable, safe and more useful for users. Our smart medical stethoscope has the ability to filter frequencies and noises, and can display heart rate indicators. Especially can be used for a long time without ear pain, can be suitable for high-end headphones. Current technology is using sound transmission in the air, cannot be used in environments with loud noise, especially causing ear pain due to being clamped in the ear. Our devices can be used in noisy environments, can filter frequencies, can display heart rate and provide hazard alerts.
