What is a dual stethoscope?

The stethoscope is a medical device for listening to the inner sounds and rhythms of the body such as lungs and hearts. It can also be used to listen to blood flow in veins and intestines. A single stethoscope of the head is usually used to listen to the heart. The dual stethoscope has two listening surfaces. The larger side is generally used to listen to high -frequency sounds in the heart and the smaller side listens to lower frequencies in the lungs.

There are many types of dual stethoscopes to buy and are manufactured for use in adults and infants. The common dual stethoscope is Littman Stettoscope. The individual stethoscope is sometimes called a "heart stethoscope" and tends to have a clearer and more focused sound. The dual stethoscope is usually made of medical stainless steel of high quality and has resistant inner tubing. The membrane side has a tight surface similar to a drum that increases the sounds of the inner functioning of the body.

double -sided steakSkop was developed in the 40s of the 20th century and quickly became a measure that was designed by all other dual stethoscopes. The side of the membrane or side used for the listening of the heart is a party composed of a thin drum film and the smaller side is actually concave, hollow shape and used to listen to breathing and lungs of the patient. The surface of the diaphragm is used to listen to the inner vibration waves that travel to the ear stethoscope. The smaller, bell side works to listen to vibrations from the skin and then sent them to the stethoscope to diagnose the doctor. Some of the dual stethoscopes are designed to rotate without actually overturning the device and must be regularly lubricated to prevent the equipment and can affect the acoustics.

While dual stethoscope does not have as wide listening range as the only stethoscope of the head, or as a sharp sound, is more versatile and doctors often choose this device as their primary stethoscope. The wider side of the dual stethoscope withIt calls the side of the membrane mode and the smaller side is called the bell side. The wider end is useful in listening to irregularities in the heart. The smaller end of the dual stethoscope is usually used to listen to breathing irregularities. The doctor is able to simply overturn the head of the stethoscope to listen to different parts of the body.
