A stethoscope is a medical device which is used to listen to the internal sounds of human beings or even of animal body. It is one of the most essential piece medical instruments. A stethoscope can also be put in work to listen to the sounds made by lungs, intestines, heart and as well as the flow of the blood in veins and arteries.
Since stethoscope made it’s entrance in the medical field, it has evolved a lot in terms of technology and also in terms of what the professional specialists and doctors actually look for when they listen through it.

What all parts does a Stethoscope consist of ?

A stethoscope consist of eight ( 8 ) important parts:

  1. Chest piece

    Chest piece is also known as the as the head of the stethoscope. It is round in shape. It is the part which is put against the chest of a patient’s body in order to hear the internal sounds. Works best when put directly to the patient’s skin. The responsibility of a stethoscope is to detect, capture and transferring sound to the headset. Also, it is the most important part amongst all the other parts of the stethoscope.
    It totally depends on the model that a stethoscope would either have a one-sided or two-sided chest piece.

  2. A Diaphragm

    The circular end and the round part of the chest piece is known as a diaphragm. It is the large size of it which allows you to listen to the wider area of the patient’s body. It’s speciality is that it can detect sounds of higher frequencies.
    These days, the diaphragm are designed in such a way that the patient does not feel chill of it when put directly to the skin of patient.

  3. A Bell

    A bell is a circular end of a chest piece. Because of it being smaller in size, It can detect sounds with lower frequencies in comparison to the diaphragm and is totally ideal for, what are to be known as the smaller body parts.

  4. A Stem

    The part which connects the chest piece to the tubing of the stethoscope is known as the Stem. It is usually made up of steel or metal, It also ensure a secure link for the optimum performance. It can also allow you to switch between the bell and diaphragm or vise a versa.

  5. A Tubing

    The tubing is a PVC material pipe or a rubber that simply connects the chest piece to the stethoscope. Its’s natural function is to transfer the sound waves picked up by the diaphragm and the bell to the headset with minimum quality loss, It all basically depends on the type or the quality of the tube.

  6. A Headset

    The headset is considered to be the upper half part of the stethoscope. It makes sure that there’s a efficient flow of the sound that goes to the ear canal with least disturbance possible.

  7. An Ear Tube

    The hollow metal tubes that connect the acoustic tubes to the ear tips is known as an ear tube. The tension springs usually rest between the ear tubes which helps you to decide and adjust how tight your stethoscope should sit on your ears.

  8. And Ear Tips

    The part that goes inside the ear is known as a ear tip. Ear buds are usually made out of silicone or rubber. They are normally placed on the ends of a ear tubes and further have a hole in the middle for letting out the sound. The ear tips should generally be soft and yet should be quite hard to create a seal in your ears and eliminate all the external sound.

What all are the types of Stethoscope ?

Just like technology everything has changed even the way how stethoscopes used to work earlier. The main types of stethoscopes are:

  1. Acoustic Stethoscope

    It works by focusing more sound waves towards the ear than it would normally be reaching. The sound waves must produce certain kind of vibrations in air molecules that cause changes in air pressure which make our eardrum vibrate in turn and in order to hear a voice. Sounds like stomach gurgling or a heart beating cause sound wave naturally, which hits the metal chest piece the moment you place it on the patient.
    The sound waves are then channelled further through a rubber tube towards a specific direction until they hit the metal piece and then finally the ears. Because tubing is responsible for carrying the sound waves, a lot of them would reach your ears than it would naturally / otherwise, while amplifying the sound. That is the reason why listening to a patient’s heart beat on stethoscope is way much clear and louder than you usually would hear while putting your head directly to their chest.

  2. Electronic Stethoscope

    Electronic stethoscopes are also known as digital stethoscope. They have limitation as to how much they can amplify the sounds, unlike acoustic stethoscope. Electronic stethoscope picks up the physical vibrations of the sound, and changes them into an electronic signal and further optimize them for enhanced diagnosis and listening. Some of the electronic stethoscopes also carries the ability to diminish the background noises in addition to simply increase the volume accordingly.
    Most of the electronic stethoscope are designed just like any other stethoscope available. These kind of stethoscopes are either rechargeable or battery powered, so if you have not charged it or if the battery is dead, it won’t work at all.

  3. Stethoscopes for Hearing Impaired

    There are ample amount of options available for medical professionals who are hearing impaired. These kind of stethoscopes increases the volume in order to make the more audible. If you don’t wear any kind of hearing aid then you can use these kind stethoscope very normally and conveniently. And if you do wear any kind of hearing aid then you can try a special kind of adapters known as stethomate tips. These tips allows / helps you to use the stethoscope along with your hearing aid.
    If you get uncomfortable with wearing your traditional stethoscope along with your hearing aid, another option is of using a digital stethoscope that gives you the access to plug in headphones.

  4. Cardiology Stethoscope

    Cardiology stethoscopes are used in the cardiac assessments, as the title suggests. These kind of stethoscope are used to differentiate between different types of sounds of the heart in order to get the most precise diagnosis.

  5. Pediatric Stethoscope

    Little patients need equally small medical instruments as per the convenience / requirement. The pediatric stethoscope looks just like any other stethoscope but only the head of the it is scaled down till the time it’s about an inch in diameter. Infant stethoscopes are available too which consist of smaller chest pieces for every tiniest infants.

  6. Veterinary stethoscope

    Veterinary stethoscopes should be considered by doctors or medical specialists, who treat animals. It’s specially designed for mammals other than human beings. Sometimes, some veterinarians can be using an infant stethoscope / pediatric stethoscope in order to check smaller animals or pets like a hamster or birds.

  7. Sprague Rappaport Stethoscope

    This particular type of stethoscope have two ( 2 ) tubes that reaches directly from the stethoscope’s piece to the ear piece which is metal curved. The tubes are held together with metal clips in order so that they don’t separate. The double barrelled design is calculated to boost the sound quality.

  8. Select/Lightweight Stethoscope

    175-180 grams of speciality stethoscope is the heaviest that could be put in use but even the smallest increase in weight on your neck can end up being awful if you’re already having issues with neck or having a back pain. Specially, if it’s what you have to keep wearing all day long. Company like Littman do generally make couple of select and lightweight models that can weigh more in the range of 115 grams-120 grams. These kind of stethoscopes might not be able to provide you same kind of precision level that other stethoscopes offer in comparison of it.

What all types of heads are usually available in Stethoscopes ?

Traditional acoustic stethoscopes can even offer plenty of options when it turns to design of the head.
There are three ( 3 ) general types of models which are available for you to choose from:

  • Single Head Stethoscope: Just one flat, circular surface for general purpose use like hearing the heart, vital sings and lungs is offered by the single head stethoscope. These kind of stethoscopes can offer rich variety of sound frequencies and simply allow the user of it to focus either higher or the lower end of the spectrum.
  • Dual Head Stethoscope: It offer two heads in total, one on each side of the chest piece. The larger one which is known as the diaphragm, is generally flatter and works better than other stethoscopes in comparison to the other stethoscopes in terms of capturing better high frequency sounds. The smaller bell looks more like a widened up cup and surely works better with lower frequencies sounds. Some physicians or doctors who generally look after patients of all the ages, prefer to carry a dual headed stethoscope with them so that the diaphragm part should works nicely for the adult patients and the bell part is more effective for the smaller / little pediatric patients.
  • Triple Head Stethoscope: Triple head stethoscope is the most uncommon stethoscope amongst the other. It generally features three ( 3 ) heads attached to a single chest piece, as suggested by the name / title. If you look at the design of it, it is heavy and feels awkward while you use it. That’s the reason why it’s only used while performing critical cardiac assessments.
    Standard or dual head stethoscopes are commonly / mostly used by the nurses, doctors or other medical professionals.

  • What are the top ten ( 10 ) essential uses of stethoscope ?

    The following are the most important uses of a stethoscope:

  • It can be easily used to check congestive heart failures.
  • Bowel sounds can also be used to measure.
  • Can check the recovery rate from the surgeries.
  • Can detect sounds produced by a heart.
  • Size of a liver can be measured too.

    Which type of a stethoscope is better, Single or Double lumen Stethoscope ?

    Double lumen stethoscopes are comparatively considered to be more sensitive than the single because double lumen stethoscopes can provide an individual sound to each of the ear. This further helps in listening to the subtle characteristics of heart sounds and also murmurs in a more distinct way. Mostly, the companies produce a dual-channelled stethoscopes with two ( 2 ) lumens just inside a single tube.

    What is the actual difference between a Littmann and other Stethoscopes ?

    Littmann is proved to be four ( 4 ) times louder in a 3M test conducted which showed that the sound of a heart of an adult’s diaphragm was comparatively louder 20db ( decibel ) than that of the different brand’s stethoscope.
