A Welch Allyn otoscope is a diagnostic tool used by ear specialists to examine patients for infections or other ear-related problems. Their use is extensive as the incidence of ear disorders is high in the United States. As per the Hearing Loss Association of America (HLAA), nearly 14% of Americans suffer from some degree of hearing loss in 2024. This sums up to approximately 48 million people who have either partially or completely lost their ability.
In most of these cases, the damage could have been prevented if the ear diseases or infections were timely diagnosed. When used properly, diagnostic instruments for ear disorders, like a Welch Allyn otoscope, can detect the issues at the initial stages. Let us understand the right way of using it.
How to Correctly Use a Welch Allyn Otoscope?
The Welch Allyn otoscopes are so designed that their usage process is easy. One just has to follow the right procedure to get the best results. These steps have been given below:
Assemble the Otoscope
Take out the otoscope from its case. Select a suitable tip, also called a speculum, based on the patient’s ear canal. The specula with smaller diameters are for pediatric patients while those with larger diameters are suitable for adults.
Turn on the Light Source
After the initial assembly of its components, the light source of the otoscope is activated to visualize the internal structure of the ear. If the light source is halogen-based, the patient may feel heat and warmth during the examination. However, in the case of a Welch Allyn otoscope, this light source is a built-in LED which does not cause this warming sensation thus increasing the patient’s comfort.
Get the Patient Seated Properly
Ask the patient to stay calm and relaxed. If the patient keeps moving, not only the ear examination will become difficult but also the chances of acquiring an injury by getting hurt by the otoscope increase.
Insert the Otoscope
With one hand, gently hold the patient’s external ear. Move the patient’s head in a way that the ear canal is straightened. While holding the ear, insert the otoscope into the ear canal.
Avoid Too Much Pressure
Do not force the otoscope into the ear by applying high pressure. Rather gently move it inwards up to a point where the internal structures become visible.
Look for the Signs of Abnormalities
Once the visual is clear, notice the presence of the following in the ear:
● Redness
● Inflammation
● Lesions
● Bulging appearance
● Perforations
● Amber-colored fluid discharge
● Bubbles of the fluid in the ear
Adjust the Otoscope for Clarity
The otoscope can also be rotated for an even clearer picture. Moreover, its focus is also adjustable which results in increased clarity.
Disassemble the Otoscope
Once the examination has been done, gently remove the otoscope from the ear canal. Disassemble its parts. Remove the speculum and subject it to thorough cleaning and disinfection if it is reusable. However, in case of a disposable speculum, discard it immediately.
Let the Patient Stay Seated
During or after the otoscopy, the patient might feel dizzy. This is because our middle ear which maintains the balance of our body gets disturbed during the examination. Therefore, the patient should remain seated for a few minutes after the procedure. If the dizziness lasts longer than a few hours, refer to a healthcare professional.
Applications of a Welch Allyn Otoscope
The Welch Allyn otoscopes have the following uses in the medical field:
● A Welch Allyn otoscope can be used to detect ear-related issues such as ear pain, infections, trauma, tympanum damage, hearing loss, etc.
● These can also be employed to see if there is a wax buildup in the ear causing trouble in hearing.
● The physician can also check the flexibility of the eardrum simply by adjusting the air pressure using the Welch Allyn diagnostic system.
Advantages of a Welch Allyn Otoscope
The Welch Allyn otoscopes are great devices for ear examination owing to the following reasons:
● As the Welch Allyn otoscopes are portable and lightweight devices, they can be easily carried around by physicians.
● These otoscopes are smaller in size so are easy to handle by the physicians. The previous versions of the otoscopes came with charging points which were tough to handle and bulky.
Limitations
An otoscope cannot visualize the inner ear i.e. the deepest part of the human ear. Rather, it can only visualize the ear canal and the eardrum called the tympanic membrane. However, the condition of the inner ear can be estimated by the signs of the disease visible in the outer and milled ear.
Risks Associated With Otoscope Use
A Welch Allyn otoscope, if used incorrectly, can cause the following conditions:
● If the patient has an ear infection or inflammatory condition, the tip of the otoscope might irritate or puncture the eardrum. However, when used with care, this complication can easily be avoided.
● If the tip or the speculum of the otoscope is not changed or cleaned after use in a patient, it can become the cause of transferring infections to other patients by cross-contamination.
Maintenance of a Welch Allyn Otoscope
A Welch Allyn otoscope can be cleaned and maintained in the following way:
● The handle and head of the Welch Allyn otoscope should be wiped down properly using a lint-free cloth. For the lens, the use of a lens paper is recommended.
● For this purpose, 70% isopropyl alcohol (IPA) should can be used.
● Instead of IPA, EPA-registered hospital disinfecting/cleaning agents can also be used.
● The solution should be applied in a suitable concentration to prevent them from seeping into the Welch Allyn otoscope.
● If the solution is seeped into the system, visibility can be hampered.
● Store the otoscope in a dust-free place. The batteries should be removed for long-term storage.
Warning
● Do not use the device if it is damaged.
● Do not use the Welch Allyn otoscopes in the presence of flammable anesthetics.
● Do not use disinfecting chemicals like ethylene oxide gas and glutaraldehyde on the Welch Allyn otoscope.
● The use of steam should also be avoided as it can damage the device.
● Avoid contact with the eye.
