As we move though the summer, back-to-school time is creeping up on us. Before you know it, the school year will begin. If you are in need of a good quality STETHOSCOPE, this blog is for you.
Wikipedia presents the roots of the stethoscope this way: “The stethoscope was invented in France in 1816 by René-Théophile-Hyacinthe Laennec. It consisted of a wooden tube and was monaural.”
It is hard to buy a stethoscope for others, so at Vitality Medical we have some tips that will make your stethoscope buying experience a rewarding one. Because, nobody wants an unwanted stethoscope sitting around.
Stethoscope School 101
The stethoscope is made of three main components: the Diaphragm, Acoustic Tubes, and the Headset.
The Diaphragm The part that is exposed to the patient’s body is the diaphragm.. Often times this chestpiece is two sided with a diaphragm on one side and a bell on the other.
When the diaphragm is used, the patient’s body sounds vibrate the diaphragm. The resulting sound waves travel through the tubing to the ear tips. When the bell is placed on the patient, the vibrations come from the skin to produce sound waves. The diaphragm is used for higher frequency sounds and the bell for low frequency sounds.
Some stethoscopes have detachable bells and diaphragms so that a Doctor, Nurse, or Student can switch between bell and diaphragm. They may also attach a pediatric diaphragm on one side and an Adult diaphragm on the other.
The Acoustic Tubes
Often overlooked, the tubing is a crucial part of the stethoscope. Because of latex allergies, the tubes are made of a non-latex synthetic rubber. The tubes should be dense in this construction so environmental noises don’t interfere with the examinations.
The two most common tube configurations are “Y” and “Dual.” A “Y” configuration is where one tube comes out of the chestpiece and splits with a tube going to each of the ear tips. A “Dual” tube configuration is where two separate tubes come from the chestpiece and go separately to the ear tips.
Perhaps the most important part of the stethoscope is the Headset. This is the part that will be the most comfortable or uncomfortable to the medical professional or student. The Headset is made of the ear tips, spring, and the lightweight metal frame that holds it all together.
The “spring” forces the headset to a closed position. A medical professional can wear the stethoscope around their neck or in their ears leaving their hands free. The ear tips go into the ears. They should be comfortable and provide a seal in the ear canal to block out noise.
