If you have ever been affected with an ear infection? If yes, you must be familiar with otoscopes, the ear examination tools that help visualize the interior ear by shining a bright light into the ear canal. These otoscopes also have a magnifying lens to increase the image size as well as a reusable or disposable tip called a speculum. In the case of reusable tips, cleaning the otoscope specula becomes essential to reduce the risk of infection transmission.
Otoscope specula are available in both disposable and reusable options
In this article, let us learn about the cleaning and maintenance of otoscope specula. Moreover, for the reader’s convenience, some of the top otoscopes available in the US have also been linked.
What are Otoscope Specula?
A speculum (pl. specula) of an otoscope is the cone or funnel-shaped tip that is inserted into the ear canal during examination. It is a detachable component of the device that allows the healthcare provider to look into the ear and observe if there are any signs of a disease or infection.
These reusable or disposable specula are lightweight and easy to attach and detach from the otoscope head. Moreover, their construction material is food-grade plastic that is non-toxic and free from natural rubber latex to minimize the risk of irritation.
Functions of Otoscope Specula
Disposable ear specula push the ear tissue to the sides gently so that the ear canal can widen and thus visualization is improved.
Why is the Sterilization of Otoscope Specula Necessary?
The used otoscope specula as well as the otoscope heads harbor microbes that can get transferred from one person to another. Studies have confirmed the presence of bacteria like Pseudomonas and Staphylococcus on these components of the otoscopes.
In addition, Aspergillus species of fungi are also likely to be present in most cases. Some instruments can also have Candida albicans. These pathogenic organisms can be removed from the otoscope specula if they are subjected to thorough cleaning and sterilization.
Disposable specula can be easily mounted and dismounted on the otoscope head
Sterilization of Otoscope Specula
To sterilize the otoscope specula, the following steps serve as a guide. However, if your healthcare facility has preset guidelines about cleaning and sterilizing otoscope specula, consult them first. Moreover, the otoscope manufacturers also provide cleaning instructions with the products that are also often helpful.
1. Removal of Visible Debris
The first step in cleaning the used otoscope specula is the removal of the visible debris. A soft brush can be used for this purpose. The specula can also be held under running water to allow the cleaning of the debris. However, the use of fresh hot water and detergent is also recommended if the running water is not enough.
2. Soaking in Disinfectant Solution
Once the visible debris has been cleaned, the next step is to soak the otoscope specula in a suitable disinfectant solution for at least 20 minutes. This helps clear out all the microbes that can potentially cause an infection.
Disinfectant Solutions
The disinfectant solutions used for wiping the otoscope specula have the following active chemical agents:
- 70% isopropyl alcohol
- Chlorhexidine gluconate
- Cetrimide
- Sodium hypochlorite
- Dichlorometaxylenol
- Diluted bleach solution
It is important to remember that all of these solutions are not suitable for metal items.
Specula of different sizes help accommodate patients from different age groups
3. Rinsing and Drying
After thorough cleaning and sterilization, the otoscope specula should be washed with a running stream of water. This will allow the removal of disinfectant solution from the otoscope specula. Once cleaned, these should be put on a clean and dry cloth until they are completely air-dried.
4. Storage
Once the otoscope specula have been dried, store them in a clean and dry container until future use.
Caution
While cleaning and sterilizing the otoscope specula, always remember the given instructions:
- Never sterilize the otoscope head as it has several electrical components. Rather, just wipe it with a lint-free cloth dipped in a suitable disinfectant solution. Apart from this, commercially available disinfectant wipes can also be employed.
- Dipping the plastic-based otoscope specula for too long in the disinfectant solution can result in the deterioration of the product.
- If the disinfectant solution is stale, it might have become ineffective against microorganisms. As a result, there may be microbial buildup that could increase the risk of infections rather than decrease it.
- If cleaning and maintaining otoscope specula is difficult, opt for disposable ones that can be discarded after a single use.
- The use of gloves must be ensured while handling used otoscope specula.
Most otoscope brands provide multiple specula with the product
