A stethoscope with a bell is a diagnostic tool used by physicians to listen to a person’s heartbeat, or other internal body sounds. This device works on the principle of acoustic impedance. The stethoscope is a long tube with an earpiece at one end. The earpiece is connected to a diaphragm that vibrates at varying frequencies. A doctor or nurse places the stethoscope around the chest and presses on the bell part of the stethoscope. The stethoscope then measures the vibrations or sounds in the tube.
Types of Stethoscopes
Acoustic Stethoscopes
An acoustic stethoscope is a medical device that amplifies the sound of the heart in order to detect abnormalities. This stethoscope has a diaphragm that alternates between two modes, one that transmits sound waves as well as one that blocks them. It is capable to channel more sound waves that are contained by the tubing. This causes more vibrations in air molecules.
Electronic Stethoscopes
An electronic stethoscope works by converting the sound picked up by the diaphragm of the stethoscope into electrical signals that are amplified, filtered, and stored for later analysis. The stethoscope’s sensor and amplifier get power from a single, replaceable battery.
Specific Uses of Stethoscope with Bell
Calculate Blood Pressure
A stethoscope can now accurately calculate a person’s blood pressure. The device consists of a sensor that the doctor places on the person’s skin to measure blood flow. Electrodes in the stethoscope measure the pulse and blood pressure and transmit the data wirelessly to a computer. The computer records the measurements as well as compares them to a standard reference.
Determine Lung Sounds
A stethoscope like Blue 3M Littmann Classic III is a tool, you can use for listening to and assessing heart, lung, and blood vessel function. Lung sounds reveal details about a person’s lungs and respiratory system. The three most common lung sounds are crackles, wheezes, and rhonchi. A doctor can identify the air blockage or breathing problem by comparing measured lung sounds with the standard rate of the patient.
Detect Heart Sounds
A stethoscope is good at detecting heart sounds. Sound waves travel along the arteries and veins in the blood. The stethoscope picks up these sound waves and translates them as vibrations. It turns vibrations into audible sounds, that the medical professional hears. This helps doctors in diagnosing pulmonic, aortic, tricuspid, as well as other heart problems.
Check Congestive Heart Failure
Stethoscopes like 3M Littmann Classic III offer the perfect way to find the cause of abnormal heartbeats. A doctor uses stethoscopes to detect congestive heart failure. Improper sounds in the heart and lungs can be because of congestive heart failure.
