A stethoscope is a must-needed equipment for your medical journey starting from MBBS the first year of your professional career. The first step before buying a suitable stethoscope should be understanding its parts and specifications. In this blog, we will help you understand all you need to know about a stethoscope.
A stethoscope and its eight parts:
- Chest Piece
- Diaphragm
- Bell
- Tubing
- Stem
- Headset
- Ear tubes
- Ear tips
Chest Piece:
The device's core component is a circular piece called the chest piece, which is also referred to as the head. This is the device component that is in contact with the patient's body. It is composed of a diaphragm, bell, and stem.
Diaphragm:
The diaphragm is the chest piece rounded and circular end. You can listen to a greater portion of the patient's body thanks to its size. It can pick up higher-frequency noises in large areas of the patient.
Bell:
The bell is the term for the chest pieces' circular end. It is perfect for small body parts because, due to its smaller size, it can detect lower-frequency sounds than the diaphragm. The edges of the bell also have a non-chill ring.
Stem:
The component known as the stem joins the stethoscope tubing to the chest piece. It ensures a secure connection for the best performance and is composed of steel or metal. You can also choose between the bell and the diaphragm.
Tubing:
The flexible PVC or rubber pipe that joins the chest piece to the headset is known as the stethoscope tubing. This stethoscope component efficiently transmits the sound waves captured by the diaphragm and bell to the headset.
Headset:
The headset is located on the upper half of the stethoscope. It is made of ear tips, tension springs, and two ear tubes. It makes sure that sound enters the ear canal effectively, causing the least amount of disruption possible.
Ear Tubes:
Acoustic tubes and ear tips are joined by ear tubes, which are hollow metal tubes. They offer sound waves through the left and right channels to go through. You may modify how tightly your stethoscope is resting on your ears by adjusting the tension spring, which is located between the ear tubes.
Ear Tips:
The components that fit into the ears are the ear tips, which are manufactured of silicone or rubber. They fit on the ends of the ear tubes and feature a hole in the center for sound release. To seal your ears and block out all external noise, ear tips should be both soft and solid.
