A stethoscope is a form of acoustic medical device used for listening to internal sounds of the human or animal body. It is also known as a phonendoscope. It is used to hear the heart, lungs, intestines and blood flow of arteries and veins. It is mainly used by doctors while measuring the patient's blood pressure.
Pediatric Stethoscope – It has a tiny section of the chest that the doctor can place precisely over the infant body. One of its benefits is it looks like a toy for infants.
Electronic Stethoscope is suitable for people with hearing problems by amplifying the sound generated from the chest component. This sound is then translated into electric waves. An electronic stethoscope delivers a broader spectrum of sound frequencies than ordinary stethoscopes.
Digital Stethoscope allows the user to switch between digital and analogue amplification. The device enables the detection of various diagnostic sounds. A digital stethoscope works on rechargeable batteries as a power source.
Neonatal Stethoscope – It is the smallest Stethoscope used on newborn babies. The neonatal Stethoscope has the smallest diameter that performs functionality without disturbing surrounding noise.
Chest Piece is mainly made up of high-density materials like steel or titanium.
Headset – Ideally, it is suggested to have a headset made up of the same material as the chest piece. It is placed at a 15-degree angle. The acoustic waves are first entered in a chest piece and then transferred to the headset.
Diaphragm – It is made up of high-quality PVC material that improves the device's durability. The diaphragm is used for the detection of high-frequency sounds.
Ear Tips – It is good to have proper fit ear tips for experiencing clear sound effects and filtering out unwanted sounds.
Stem – A durable stethoscope must have a stem made of the same material as the chest piece and headset. The dual-headed device has a rotating valve that allows the selection of one side of the chest piece.
Tubing is usually made up of PVC material and is used to transmit the sound from the chest piece to the ear tube.
Bell – It is used for the detection of low-frequency sounds.
It helps detect normal versus abnormal heart sounds and diagnose valve functions.
It can also diagnose different respiratory diseases like bronchitis and pleurisy.
This device is used to compare the movements in the normal versus abnormal intestinal tract.
