Fact #1. The stethoscope was invented in France in 1816 by a physician. Its original design was monaural, and consisted of a long wooden tube. The physician felt uncomfortable placing his ear directly against the chests of his patients. The wooden tube allowed him to listen to a patient's heartbeat without making physical contact.
Fact #2. The design of the binaural model was perfected in 1852. This was more durable than the previous design. It had individual earpieces so that the sound could reach both ears simultaneously. This became the standard for the medical stethoscope that is still in use today.
Fact #3. The stethoscope is closely associated with a trip to the doctor's, particularly for kids who need regular checkups. Regardless of the situation, it's a necessary part of the medical tool arsenal. It's an acoustic medical device for listening to the internal sounds of a person or animal's body parts. A doctor or nurse will often use them to listen for abnormal rhythms of a person's heartbeat, breathing irregularities, compromised lung functions, and to monitor blood pressure.
Fact #4. When choosing an option to buy, the particular profession you have in mind is an important consideration. A cardiologist, for example, would benefit from one that can easily detect both high and low-pitched sounds. One must also be sure that the earpieces fit snugly and comfortably in the ears for the best accuracy. The tubing should also be durable and well insulated in order to prevent external noise interference.
Fact #5. The best stethoscopes feature high-density chest pieces made from either steel or titanium. This allows for the best sound conduction. The chest piece should also be hand-polished on both its inside and outside for producing the most crisp sound possible. The device is also available in an array of different colors. This is useful for pediatricians who may be working with a lot of young kids.
