Understanding the anatomy of a stethoscope

 

Stethoscopes are an essential element in the life of medical professionals. It allows healthcare professionals to listen to and identify problems that patients may be suffering from. Although the device is very important for work purposes, having an understanding of different parts and names of the stethoscope will provide you with extra knowledge of how it works and how it is assembled.

Who Needs a Stethoscope?

Cardiologists, the EMT, general practitioner, medical student, pediatricians, and others need reliable stethoscopes based on their needs. For example, pediatricians need a stethoscope which is specifically designed for smaller & younger patients.  Pediatricians also need to ease the often deterring atmosphere of the hospital or clinic and thus choose colorful stethoscopes so that it adds a fun element for the kids and keeps them calm. You can shop for Littmann pediatric stethoscope and other medical products, equipment, & instruments by SMB, India's Largest Online Medical & Hospital Products Store.

How do stethoscopes work?

The stethoscope’s parts include the ear tips, ear tubes, tubing, headset, stem, chest-piece, diaphragm, and bell. When arranged together, all the parts create a functional stethoscope that helps to listen to a wide range of sounds to quickly identify and treat potential medical conditions that a patient may have.

Let’s understand the operation of these components in little detail.

Eartips

This part of the stethoscope goes into the user’s ear where they hear the sounds that come from the chest-piece. The ear tips are usually made of rubber or silicone and are designed in a way that all the unwanted sounds stay outside.

Ear tips are very important for users who spend a lot of time checking their patients’ health with their stethoscopes as they can make all the difference between a comfortable experience and an irritating experience. It should therefore be comfortable and soft.

 Because of their small size and inexpensive price, ear tips can be easily replaced on a stethoscope to have a much better experience, and it can also add a little more sound quality to the stethoscope.

Ear tubes

Ear tubes are made of metal or steel material that is attached to the ear tips and the synthetic/PVC tubing, which further connects to the stem of the chest-piece. They are designed in such a manner that it separates and transfers sound to the user with minimum quality loss.

Its function is that it is used to listen to patient sounds by placing the diaphragm or bell end of the chest-piece on the patient’s chest, back, or stomach. It works best when applied to the patient’s skin, but some stronger, high-quality stethoscopes may be able to pick up sounds through fine layers of clothing.

Diaphragm

The diaphragm is the big circular end of the chest-piece. This part of the device allows health care professionals to listen to a larger part of the patient’s body and pick up sounds of higher frequency. Some diaphragms have a non-chill, hypoallergenic diaphragm in order to provide maximum comfort to the patient.

Bell

The smaller circular end of the chest-piece is known as the bell. It focuses on a limited range, listens for lower-frequency sounds that may or may not be detected by the diaphragm. As with the diaphragm, the bell may also have a feature of a non-chill, hypoallergenic design to provide patients with extra comfort while their check-up is going on.

A stethoscope is a medical device that has many important parts that enable it to listen and transfer the internal sounds of a patient's body to the ears of healthcare professionals so that they can diagnose and treat their patients' problems with ease.

During critical medical conditions or surgeries, breathing properly becomes a strenuous activity for the patients. Providing a support for maintaining a regular breathing pattern becomes necessary. That is when the practice of endotracheal intubation started. Endotracheal intubation is a procedure in which a tube is inserted through the mouth and is slowly slid into the trachea. The flexible plastic tube that is slipped into the trachea is known as the endotracheal tube. The procedure is mostly done when the patient is under deep sedation. Endotracheal intubation was important to serve the patients a free airway passage to breathe. Air can easily pass through the endotracheal tube all the way to the lungs and keep them ventilated. They can also be connected to ventilation machines to support artificial respiration. In critical conditions, artificial respiration helps patients immensely to breathe comfortably a rhythm that is regularly monitored by Littmann stethoscopes in In...
