A stethoscope is a medical instrument used to listen to sounds in the human or animal body, such as: heart, breathing, stomach and so on. The traditional acoustic stethoscope was invented in 1816 by the French doctor Renac. The traditional stethoscope simply transmits the biological sound without any processing, so the biological sound heard will be mixed with many noises, and it is difficult to capture some important but difficult to detect biological sounds, and the traditional stethoscope cannot do anything. The captured sound signal is amplified, so for a doctor who is deaf, it will seriously affect the doctor's auscultation judgment. In order to make up for the adverse effects of the lack of hearing of doctors, and with the high development of electronic technology, the electronic stethoscope was born.
The realization principle of the electronic stethoscope is to capture the body sound of the human body or animal through a special pickup sensor, convert the captured sound signal into an electronic signal, and then restore it to sound after a series of technical processing such as filtering. As a result, the electronic stethoscope can realize various applications such as amplifying, saving and sharing of in-body sounds such as the heart and lungs. Doctors can not only adjust the volume according to their own hearing level, but also use professional analysis tools to scientifically analyze and judge the patient's pathological sounds.
The electronic stethoscope can also be combined with modern wireless communication technology to realize remote real-time consultation and wireless auscultation. Especially during the new crown epidemic, the protective effect of wireless auscultation on front-line medical staff is still obvious.

At present, the price of electronic stethoscope on the market is about 500 yuan.
The cost of buying an electronic stethoscope to listen to your own heart sounds is still a bit expensive. In fact, the principle of the electronic stethoscope is very simple. You can make an electronic stethoscope yourself.
Material: Microphone of mobile phone's external microphone and hose of single-use stethoscope
Practice steps:
1. Remove the stethoscope's ear strap hose together
2. Fold the microphone off the casing and insert the microphone head into the stethoscope hose.
3. Wrap the exposed wires with tape or heat shrink tubing.
4. Connect the mobile phone to auscultate the heart.
5. Click on your phone to record your thoughts.
Self-made cannot be played in real time, it must be recorded and played again
The stethoscope has always been a standard tool for doctors. In the future, whether we can have a cost-effective electronic stethoscope, we can also hear our own heart sounds, and can record them. There is a reference sound, so that we can also feel our own heart sounds. the mystery!
The editor believes that the times have changed and technology has continued to improve. In the future, there will be a very cost-effective electronic stethoscope in the market. Guangdong Hanhong Medical Technology Co., Ltd. has been working hard in this direction, hoping to satisfy the public and let more people feel their voices. the mystery!
