Stethoscope
Binaural stethoscope
What is its use?
Transmits body sounds for cardiovascular, respiratory and other clinical examination.
Tap a number to locate its part. Zoom, drag or use full screen to inspect the reference. Models and graduations can differ; check the actual apparatus used in your laboratory.
How to recognise it.
- Paired earpieces connected to flexible tubing
- Chestpiece placed over the examination area
- Many models have a diaphragm and a bell or a tunable diaphragm
A tuning fork produces a known vibration; a stethoscope transmits sounds generated in the body.
Point them out.
Choose a part to bring its numbered marker into view.
The science behind the reading.
A chestpiece couples mechanical sound vibrations through the tubing to the examiner’s ears.
Think first. Then reveal.
Explain your answer aloud before opening it.
01What sounds are heard during manual BP measurement?+
Korotkoff sounds over the brachial artery, not the normal heart sounds.
02How do bell and diaphragm differ?+
In a conventional design, the bell favours low-frequency sounds with light contact and the diaphragm is useful for higher-frequency sounds. Tunable designs depend on contact pressure.
03Why should the eartips fit?+
A suitable acoustic seal improves transmission and reduces surrounding noise.
04What common artefact occurs during examination?+
Tubing movement or contact with clothing can generate misleading noise.
