Stethoscope: A Handy Medical Device To Hear Your Body Sounds

Do you know, according to FoxNews, your body makes 13 different wired sounds and every of this sound means something about your body? Those wired sounds mean is your body A-okay? Or you have to schedule an appointment with your doc? But first, you need a medical device to hear those sounds, right? In this article, we are going to talk about this.

The stethoscope is a medical diagnostic device used for listening to sounds produced by the different body parts like lungs, heart, and intestinal tract of humans and animals. Stethoscopes are mainly of four types, namely acoustic, electronic, recording and fetal stethoscopes.

A basic acoustic device consists of two earpieces, a metallic binaural that connects the earpieces to the tube, a tubing, and a chest piece. The chest piece usually contains a combination of a diaphragm and a bell to transmit higher or lower sound frequencies, respectively.

An electronic amplifies the body’s sound waves using magnetic transducers. The overall make and design of the elements contribute to its value and performance. Thus it is vital to choose the top-rated stethoscope for the desired function.

What are the Different Types of Stethoscopes?

Stethoscopes come in different designs, and they differ in materials too. The majority of these devices are made of rubber tubing of Y-shape. This tube allows the device to catch the sound at its one end, and let the sound travel to the earpieces at the other end. There are many stethoscopes available with a sound-detecting device that is two-sided.

Acoustic stethoscopes

The original stethoscope model, acoustic stethoscope, operates by using a chest piece with hollow tubes that transmit sounds to the listener’s ears. The medium of transmission for the sound is the air inside the hollow tubes. The chest piece has two sides, a diaphragm and a bell. The diaphragm creates high-frequency sounds, while the bell creates low-frequency sounds. Rappaport and Sprague designed this model. The only disadvantage of the acoustic stethoscope is that the sound level is extremely low.

Electronic stethoscopes

Electronic stethoscope, also known as stethophone, amplifies body sounds using electronic transducers. These transducers convert sound waves of the body to electrical signals that are amplified and provide more transparent and louder sounds. Thus electronic stethoscopes overcome the drawback of an acoustic stethoscope of low sound levels.

An electronic stethoscope can be a wireless device because the sound is transmitted electrically. Due to this, it can even enhance and record the signals, provide noise reduction and display audio and visual outputs. Owing to these features an electronic stethoscope can be used from a distance for remote monitoring and diagnosis.

Recording stethoscopes

A recording stethoscope is a particular type of electronic stethoscope that connects the audio output to a recording device. This allows the audio output to be recorded for evaluation and consultation at a later examination. The recordings can even be shared, thus allowing for remote diagnosis as well as fast and efficient consultations.

Fetal stethoscopes

A fetal stethoscope is also known as a fetoscope. It is shaped like a trumpet and is placed against the abdomen of a pregnant woman to hear the heartbeats of the foetus. This stethoscope was invented by a French obstetrician, Adolphe Pinard and is therefore also known as “Pinard’s stethoscope’ or the ‘Pinard’ too.

How to Choose the Best Stethoscope?

For quick and correct diagnostic evaluation must possess certain qualities. It must be light in weight for ease while carrying around the neck or on the shoulder. The tube should be of adequate length, neither too long nor too short, for final patient examination. The two tubes and a large internal diameter also improve the acoustics; however, the tubes must not rub against each other to prevent unwanted sound.

The stethoscope is the basic but great tool that can diagnose severe diseases of heart or lung only by auscultating the chest of your patient, so it is important to have a top-quality stethoscope. It is good to invest some amount of money in buying this valuable lifetime assistant. The tubing should also be thick and adequately insulated to filter out external ambient noise.

The diaphragms should be made of high-quality film and be approximately 45mm in diameter for adults and 25mm for pediatric patients. The width of the chest piece, as well as its weight, affects the acoustics. It must have a non-chill ring fixated on the diaphragm from both sides to prevent contact of cold metal parts with the patient’s body.

The earpieces should be comfortable, aligning with the shape of the ear canal, and comfortable to replace and clean. Lastly, while maintaining quality, the Doctor’s stethoscope should also be cost-effective.

Benefits of Using a Good Quality Stethoscope

There are various benefits while using a Best and recommended stethoscope, for the physician as well as for the patients. It is the primary tool for which a physician starts examining the patient.

Therefore, stethoscope aids in identifying and diagnosing the symptoms faster. A real acoustic stethoscope with superior earpieces, thick insulation and tunable head within the chest piece will omit all surrounding sounds and catch every breath or heart sound.

With the help of this instrument, the physician can hear normal and abnormal sounds of the respiratory, cardiac, pleural, arterial, venous, uterine, fetal and intestinal systems.

A right stethoscope rating will help to catch a ‘whooshing’ sound in between the ‘lub- dub’ sounds of a heartbeat. The ‘lub-dub’ sounds are made by the closing of the atrioventricular valves and aortic and pulmonic valves, respectively, of the heart.

The presence of the ‘whooshing’ sound, called a murmur indicates that there is an irregularity in the flow of blood through the heart. The abnormal crackles and wheezes of the lungs or the gurgling of the stomach can all be heard and identified by a high-quality stethoscope.
