A medical equipment such as a stethoscope is necessary for medical persons to assess the internal functions of the body by hearing the areas on the body parts. Internal sounds such as wheezing of the lungs or the beatings of the pulses can be heard using a stethoscope.
Stethoscope is a classic instrument in the medical fields. It symbolizes the medical profession and it is the common medical equipment carried around by medical professionals. Hearing the internal sounds is possible because of the bell and the diaphragm, which are two sides of the stethoscope, in the chest-piece part.
The stethoscope bell is a hollow cup-shaped side attached to the flat-disc shaped diaphragm. The former is used to hear to low-frequency sound, while the latter for high-frequency sound.
Stethoscope bell causes the skin to vibrate when applied directly and then which the acoustic pressure is produced and will be transmitted to the earpiece. When using this side, make sure that you use it to patients wearing light garments.
When and where to use the stethoscope bell?
Stethoscope is used to hear the sound parts of the internal systems of the body. A stethoscope bell is used to hear intestinal sounds.
How to use the stethoscope bell?
- Tilt the ear pieces forward when worn.
- Make sure the stethoscope bell is open by rotating the chest-piece part connecting to the tubing.
- To test, tap lightly the diaphragm. If it produces a sound, then it is still open. If it does not, then the bell is open and you don’t have to worry hurting your ears. Make sure that when you do this, the earpiece is connected to your ears.
