Otoscope
Otoscope
An otoscope or auriscope is a medical device which is used to look into the ears. Health care providers use otoscopes to screen for illness during regular check-ups and also to investigate ear symptoms. An otoscope potentially gives a view of the ear canal and tympanic membrane or eardrum.
Uses[edit | edit source]
Because the eardrum is the border separating the external ear canal from the middle ear, its characteristics can give the healthcare professional a lot of information about what's happening on the other side of the eardrum.
Types[edit | edit source]
There are two types of otoscopes: pocket otoscope and standard otoscope. The pocket otoscope has a handle that uses batteries to light the viewing instrument. The standard otoscope is larger, has a cord, and is plugged into a wall for power.
Components[edit | edit source]
The otoscope consists of a handle and a head. The head contains a light source and a simple low-power magnifying lens, typically around 8 diopters (3x).
