A stethoscope is a medical instrument used for listening to sounds (auscultation) produced within the body. It is primarily used to listen to the sounds made in the heart, lungs, gastrointestinal, and to hear the sounds of developing a fetus in a pregnant woman. To check blood pressure, the stethoscope is often combined with a sphygmomanometer to listen to sounds in blood vessels. A stethoscope has a small disc-shaped resonator that is placed against the skin on the area of the body where you want to auscultate.
It also has one or two tubes that are connected to two earpieces. René Laennec, a French Doctor, and musician, invented the stethoscope in 1816 at the Necker-Enfants Malades Hospital in Paris, France. René Laennec was motivated to create this piece because he was not comfortable placing his ear directly on a woman’s check to listen to hear sounds.
Stethoscopes are medical devices, used to listen to the sounds of the human body. They are also used to listen to the body of an animal. These sounds include the heart and bowel. Doctors use them in a medical setting. René Laënnec, who was a French doctor, invented the stethoscope in 1816.
When it was first made, it was created from wood. As time and technology progressed, stethoscopes are now made from metal. Before the stethoscope, doctors would put their head against the patient's chest and listen. This method is still used today, but it is not as effective as using a stethoscope.
