What is a Welch Allyn Otoscope and How to Use One
Also known as an auriscope, an otoscope is a medical instrument that allows doctors to look inside the ear. Otoscopes can be used to screen for a variety of illnesses and conditions and are commonly used both in general checkups and specialist consultations. They are also available in a wide range of designs, with additional functionality that extends to examining the nasal canal and the throat.
First described in the 14th century and modified in the 19th, diagnostic otoscopes are one of the most recognisable and commonly used medical instruments around, and the technology has made significant advances since those early designs. Investing in high quality otoscopes, alongside other diagnostic equipment such as ophthalmoscopes, retinoscopes, stethoscopes, and sphygmomanometers will help doctors and other medical professionals to accurately assess and diagnose their patients. This in turn allows hospitals and clinics to provide patients with high-quality medical care that covers a broad range of areas.
What is a Welch Allyn Otoscope?
A Welch Allyn otoscope is standard diagnostic tool produced by well-known medical manufacturer Welch Allyn. The US-based company is one of the most well-established names in the world of medical tools and accessories. Known for the quality of its products, its consistently high standards, and its innovative instruments, Welch Allyn is a trusted source for diagnostic sets and tools of all kinds.
The otoscopes produced by the brand offer a number of useful functions and features. The company’s most affordable model is the Welch Allyn Pocket LED Otoscope. The device comes in four bright colours, making it ideal for use with younger patients and on paediatric wards. The instrument comes with either halogen HPX lighting or SureColour LED technology to allow doctors to accurately see all parts of the ear. It offers 2.5x magnification, increased battery life and a compact, lightweight design.
The Welch Allyn 3.5V otoscope is a more advanced tool with a wider choice of functions. Six different heads are available for the otoscope, giving doctors a precise, specialist tool that’s ideal for their needs. Otoscope heads available include models with throat illuminators, models that feature lithium-ion or nickel-cadmium rechargeable handles, reusable ear specula and tools for pneumatic otoscopy.
The Welch Allyn MacroView otoscope 3.5V offers doctors even better optics and magnification than other models. The instrument offers 30% higher magnification than traditional otoscopes and delivers almost twice the field of view at high magnifications compared to standard devices through the use of fiber-optic cool light technology. This can make it a lot easier to visualise the auditory canal and tympanic membrane. MacroView otoscopes are often used to enhance learning opportunities, aid decision making and boost patient outcomes.
How to Use a Welch Allyn Otoscope
Welch Allyn otoscopes are designed to be easy and intuitive to use, helping make diagnostics in patients more efficient. Adjustments can be made using the switches and dials on the head of the device, and with some instruments, you will also have the option of changeable heads. This provides the user with improved functionality and specialist features that suit a variety of examinations.
Before using the otoscope, you’ll need to check that it’s charged and the bulb is working properly. You can find out how to charge a Welch Allyn otoscope and how to change a Welch Allyn otoscope bulb by reading the instructions or FAQs that came with your device. If you need to know how to open a Welch Allyn otoscope in order to change the bulb and check the batteries, take a look at the instructions or check the information on the manufacturer’s website.
When the device is charged and the bulb is in full working order, your otoscope is ready to go. Before carrying out an ear exam, it’s important to check the ear canal for any pus or debris that could interfere with visualisation and diagnosis. Select the largest speculum that can comfortably fit in the patient’s ear canal. Make sure the focus wheel is in the default setting and then gently insert the otoscope head into the ear.
When using an otoscope, it’s essential to ensure you’re holding it correctly. When otoscopes are held incorrectly, any flinches or sudden movements from the patient can result in damage to the ear canal. Resting a finger against the patient’s neck should help to brace the otoscope and prevent the instrument causing any injuries. If the area of the ear that needs to be examined isn’t clearly visible on the first attempt, the focus of the otoscope can be adjusted for better clarity. You may need to do this multiple times to find the best setting during the examination.
If doctors want to assess the tympanic membrane, they can use a pneumatic otoscope. These use changes in pressure to move the membrane, allowing diagnosis of issues in this part of the ear. Assessing this movement allows doctors to check for conditions including middle ear effusions, vascular lesions and inner ear fistulas.
When the exam is complete, the used speculum should be removed from the otoscope to be cleaned and disinfected thoroughly before being returned. Additionally, proper storage of the specula and other accessories associated with your otoscope will help to extend their working life.
Can an Otoscope See the Inner Ear?
An otoscope allows doctors to see the ear canal and tympanic membrane. During an ear examination, an otoscope can be used to check for signs of infection, swelling, injury and other abnormalities.
Otoscopes can’t be used to check the inner ear, however, they can provide doctors with useful information about the overall health of the ear and its various components, allowing a diagnosis of the inner ear based on the results.
How Much Does an Otoscope Cost?
The price of an otoscope varies according to its functionality, design, and the range of accessories included in the specific diagnostic kit. Standard otoscopes are available for less than $150 while more advanced models can cost over $200. More advanced otoscopes are often used by specialists while standard models are commonly used for check ups and other routine procedures. The Welch Allyn PocketScope Otoscope is the most affordable in our collection, while the MacroView and Welch Allyn 3.5V otoscopes are at the top end of the range.
Welch Allyn produces a selection of accessories and parts for their otoscope range, although in many cases you will receive at least some of the accessories you need as part of your otoscope set.
