Frequently asked questions:
What type batteries do Dr
use, and will re-chargable's also work?
with 2 readily available and easily replaceable AAA batteries.
Rechargeable AAA batteries can be
purchased separately and also work well with our otoscopes.
Will disposable specula
work with Dr Mom Otoscopes
Yes, most disposable specula brands found in the
USA and Europe work well with our otoscopes. We also sell them
on our website.
What is the difference
between the LED Dr Mom Otoscope® and the Original Dr Mom
Otoscope® that uses a krypton bulb?
The Dr Mom LED is the first otoscope to ever make
use of a LED light source. The biggest advantage of an LED light
source over all the other otoscopes on the market which use
incandescent light sources is that the LED bulb contains no
fragile filament that can be easily damaged and or burn out over
time. The LED light source lasts essentially forever and will
not be damaged by rough handling, dropping, or sudden movement.
The LED light source is also brighter and consists of full
spectrum light instead of the yellowish light found in all
incandescent light sources.
What color is the light from
the LED otoscope?
The LED emits a full spectrum
light color. This appears as a white light with a slight bluish
tint. Full spectrum light is the the same spectrum of light that
is emitted by sunshine. Full spectrum light will give you the
most true appearance of an object viewed under it. There is a
very good explanation about the advantages of full spectrum
light on the OTT-LITE®
http://www.ott-lite.com The OTT-LITE® was
specifically developed for hobbyist who needed full spectrum
light similar to sunshine to get the most accurate and truest
color from the objects they were working with.
You will notice the
difference in the color of the board that the lights above are
shining down on. The true color if taken out in sunshine is what
you see under the OTT light on the left and not that of the
yellowish light produced by an incandescent bulb in the lamp on
How does the brightness of the LED light compare to the halogen
light in the larger professional type otoscopes?
Surprisingly our LED light source
is actually brighter when measured with a photometer than the
halogen light source on our Professional model otoscope yet
burns cool and uses 1:20th the amount of power. If you darken a
24' by 24' room and stand at one end of it you can literally
throw a bright beam of light onto the opposite wall through the
specula tip of this otoscope.
Bottom line is that there will
never be an issue with needing more light in an ear canal.
How long will the LED light
last before it will need replacing?
If you left the LED light source turned on and running
continuously it would burn for 25 years before it would need
replacing. It would also maintain its same brightness during
these 25 years of continuous use before it finally died and went
Will rough handling or
dropping of the LED light cause it to burn out prematurely?
LED light source does not contain a fragile filament as does all
the incandescent light sources found on all other
otoscopes on the market today. We hold the patent and are the
only company that offers an LED otoscope. One of the greatest
advantages of having an LED light source is that the LED bulb is
almost indestructible when it comes to dropping the otoscope or
handling it roughly in any way. This is not the case with all
other otoscopes on the market because they all use incandescent
bulbs. Incandescent bulbs contain a fragile filament that burns
hot. These bulbs are easily damaged with any rough handling or
sudden movements. These bulbs also need routine replacement over
time similar to the bulb in your table lamp at home which is
also an incandescent bulb. The bulbs are also very expensive to
replace, costing over $30 for the most common and well known
brand of otoscope found in the US today.
What is the magnification of
the otoscope lens?
Our otoscope lens uses between a
3x- 4x magnification. We use the same magnification and focal
length as the standard Welch Allyn®
otoscope. We actually used their lens as our prototype when
developing our otoscope. We figured they have been around for
over 100 years and are the leading manufacturer of otoscopes in
the world today and would be our best guide to what the optimum
magnification and focal length should be.
Is higher magnification
Bigger is not always better when
it comes to looking in the ear at the eardrum. The key to
finding the proper magnification is to deliver enough
magnification that you are able to get a clear picture of the
eardrum as a whole yet at the same time magnify it enough to see
the details that are important when doing your exam. If you over
magnify you can see very clear details of a small area but you
are unable to get a clear picture of the entire eardrum. Again,
we allowed Welch Allyn®
to decide what is the optimum magnification and focal length to
use and then had our lens manufacturer use these same values
when creating the Dr Mom Otoscope® lens.
Does the smaller viewing window of a pocket otoscope make it
more difficult to see the eardrum than it would with the larger
professional otoscopes that have a larger viewing window?
Even though the viewing window is
smaller on our pocket otoscope than it is on larger professional
models it does not limit what you see in the ear canal. The
limiting factor on an otoscope is not the viewing window size
but the diameter of the specula tip that is being inserted into
the ear canal. Since the specula tip size is the same for our Dr
as it is for the professional models the view of the eardrum is
exactly the same.
What is the size and weight
of the Dr Mom Pocket otoscopes?
are around 7 inches long and
weigh 4oz with batteries. They are much lighter and easier to
hold in your hand than the heavier professional models. This
becomes especially important if you are using the otoscope to do
an exam on an uncooperative child. They also fit nicely in a
coat pocket and come standard with a pocket clip to make sure it
stays in place when clipped in your pocket.
Is it difficult for parents
to learn to do ear exams?
This is one of those questions
that has two answers....yes and no. The key to doing ear exams
is practice. It is important to begin doing otoscope exams on a
willing adult as opposed to a child. The ear canals are larger
and the eardrum is easier to see in an adult. The key is to look
into as many adult ear canals as possible to get a feel for what
normal eardrum looks like. When you visualize an eardrum that is
red, has fluid behind it, or is simply abnormal you will quickly
The old saying practice makes
perfect could not apply more to any situation than it does to
doing ear exams.
It is also always important to
always go slow and never ever force or pry the otoscope in an
ear canal in any way shape or form. Always look to see what is
in front of you through the viewing window of the otoscope
before advancing it into an ear canal. Never push the specula
tip into the ear canal unless you have a clear view that there
is nothing in front of you.
Realize that in some children and
even adults it is impossible to see the eardrum. Some children
and even adults have very small ear canals and/or also filled
with earwax and debris which make it impossible to see the
eardrum. Even as a physician it is impossible to see into some
It is also advisable especially
with pediatric exams to get the help of your local pediatrician.
Many pediatricians today are very supportive of home ear exams
and recognize the value of parents being able to monitor for the
earliest signs of ear infection. Pediatricians also recognize
the importance of the early recognition of earwax occlusions that can
cause hearing loss. If not recognized early this hearing loss
can go on to affect the speech
development in young children.
