Electronic stethoscope

Use Electronic stethoscope

Innovation in medical technology has led to the invention of the electronic stethoscope. It is the digital stethoscope which is used for amplifying the low body sound levels. This enables healthcare practitioners like doctors, nurses and lab technicians to diagnose the condition of the patients precisely. Electronic stethoscope makes use of advanced technology to hear the low sounds of the body. The acoustic sound waves are converted into the digital signals which are more amplified to make it audible through the earpieces.

Methods used in the electronic stethoscope

The simplest way to use the electronic stethoscope for detecting the body sound is placing the microphone in the chest piece. Another technique which is popularly used in the electronic stethoscope is putting the piezoelectric crystal in the metal shaft head. This shaft is then taken into contact with the diaphragm to listen to the body sound.

In addition to this, there are some manufacturers of electronic stethoscope who use the electromagnetic diaphragm to make the capacitive sensor. This type of diaphragm has the conductive inner surface which makes it easier to respond to the body sound waves just like the conventional acoustic stethoscope. The changes in the electrical field are replaced with the changes in air pressure, and hence it gives the more amplified sound of the acoustic stethoscope.

Wireless experience of using the stethoscope

An electronic stethoscope is wireless which makes it more convenient to use. This type of stethoscope doesn’t have auditory conduit. Therefore, it enables the doctors or nurses to listen to the body sound of the patients more clearly even from a distance. This feature of electronic stethoscope makes it suitable for diagnosing the patients suffering from the infections. Another feature of this stethoscope is that you don’t need to back up it's functioning by supplying the electricity. It runs on batteries and hence it is more portable and easy to use. The powerful batteries of this stethoscope last up to a month because such stethoscope has the auto power shut off feature which makes it easier to save energy.
Record and replay feature of the Electronic stethoscope
Record and replay is another exciting feature of the electronic stethoscope. It is helpful in recording the data in their external or internal storage space. Hence, it is more convenient for the medical professionals to analyze the body sounds by replaying it later. The records can also be attached with the detailed medical file of the patients.
