A stethoscope is an instrument used by healthcare professionals to detect and study heart, lung, and stomach sounds in adults, children, and animals.
It is a lightweight device with two earpieces and a chest piece attached at the ends. The earpieces are designed to rest comfortably in the ear canal, so the doctor can hear everything they need to make an accurate diagnosis by placing the chest piece on the patient’s body.
A stethoscope has two main heads (dual-head stethoscope), the bell and the diaphragm. The bell head detects lower-frequency noises, such as heart murmurs or breath sounds, and the diaphragm picks up high-frequency noises, such as crackles in the lungs or wheezes.
You can use this device to listen for normal breath sounds in the upper and lower lobes of the lungs, as well as on the front and back of your patient’s chest. It can also help you to check heart rate, heartbeats, blood pressure as well as bowel sounds.
The History and Origin of the Stethoscope
The stethoscope was invented in the 18th century by French physician Rene Laennec. He was tired of putting his ear on a female patient’s chest to pick up her heartbeat, so he came up with the idea of rolling up a tube and using it as a funnel to amplify the sounds inside her body.
In the 1820s, a series of physicians began to experiment with the idea of making the stethoscope more durable and easier to use. A British doctor named Golding Bird created a flexible tube version of the stethoscope in 1840. A decade later, Irish doctor Arthur Leared invented a binaural (two-ear) single head stethoscope model that was made of gutta-percha and displayed at the Great Exhibition in London in 1851.
In the 1960s, Harvard Medical School professor and cardiologist David Littmann designed a modern double headed stethoscope that was light, had improved acoustics, and had the ability to be tunable, or adjustable, for lower or higher-pitched sound. This was a major breakthrough for stethoscopes and has been adopted by hospitals and physicians around the world.
How Does a Stethoscope Work?
The stethoscope is a medical instrument that allows doctors to hear the sounds of a patient’s heart and lungs. It’s often used in hospital settings and during physician visits.
A stethoscope’s working process is called auscultation. Doctors use it to listen to body sound waves and to identify problems and abnormalities that require further investigation.
Traditional stethoscopes transmit sound from the chest piece, through air-filled hollow tubes, to the ears of the physician. These acoustic stethoscopes have two parts to detect sound, the bell that transmits low-frequency sounds and the diaphragm that transmits high-frequency sounds.
