II INTRODUCTION
The Visiomed Thermo Flash LX-26 thermometer without contact
has been developed using latest infrared technology This
technology allows temporal artery (TA) temperature to be taken at a
distance of about 5cm away from the forehead
Precise, Instantaneous and without Contact, the Thermo Flash
LX-26 is, to date, the most suitable thermometer for no risk
temperature measurement It has been demonstrated that this
method of TA temperature measurement is more precise than
tympanic thermometry and better tolerated than rectal
thermometry (1)
However, as with other types of thermometer, it is essential to use
the Thermo Flash LX-26 properly in order to obtain reliable and
stable results
You are therefore advised to read this instruction manual and the
safety precautions carefully before use

Use in Infants Arch Pediatr Adolesc Med 2001;155:376
III PRECAUTIONS BEFORE USE
The Thermo Flash LX-26 is pre-set at the factory.
It is not necessary to calibrate the device when
starting it up.
In order to obtain reliable and stable results, you are advised each
time there is a significant change in the ambient temperature due to
a change in environment, to allow the Thermo
Flash LX-26 to
acclimatise to this ambient temperature for 15 to 20 minutes before
using it
It is important to allow a one minute interval between two
measurements

ThermoFlash LX-26 User Manual – English V 15 200904 5
IV OPERATING PRINCIPLE
All objects, solid, liquid or gas, emit energy by radiation The
intensity of this energy depends on the temperature of the object
The Thermo Flash LX-26 infrared thermometer is therefore able to
measure the temperature of a person by the energy the person
emits This measurement can be taken thanks to an external
temperature probe on the device which permanently analyses and
registers the ambient temperature Therefore, as soon as the
operator holds the thermometer near the body and activates the
radiation sensor, the measurement is taken instantly by detection of
the infrared heat generated by the arterial blood flow Body heat
can therefore be measured without any interference from the heat
of the surrounding environment
T E DIFFERENT MET ODS OF TEMPERATURE MEASUREMENT
Core temperature
Core temperature is the most precise measurement and involves
measuring the temperature in the pulmonary artery by means of a
catheter equipped with a thermal probe which can read the
temperature in situ The same method is employed for probes
measuring the oesophageal temperature However, such invasive
temperature measurement methods require specific equipment and
expertise
Rectal thermometry
Rectal temperature adjusts slowly in comparison to the evolution of
the body’s internal temperature It has been demonstrated that
rectal temperature remains raised long after the internal
temperature of the patient has started to drop and vice versa
Furthermore, rectal perforations have been known to occur as a
result of this method and without appropriate sterilisation
techniques, rectal thermometry can spread germs often found in
faeces

ThermoFlash LX-26 User Manual – English V 15 200904 6
Oral thermometry
Oral temperature is easily influenced by recent ingestion of food or
drinks and by breathing through the mouth To measure oral
temperature, the mouth must remain closed and the tongue
lowered for three to four minutes which is a difficult task for young
children to accomplish
Axillary (armpit) temperature
Although it may be easy to measure axillary temperature, it has
been proven that it does not provide an accurate measurement of
the child’s internal temperature To take this type of temperature,
the thermometer must be wedged tightly over the axillary artery
Despite the low sensitivity and relative inaccuracy of axillary
temperature in detecting fever, this method is recommended by The
American Academy of Pediatrics
as a screening test for fever in
newborns
Tympanic thermometry
In order to obtain a precise temperature reading, good command of
the measurement technique is required The thermometer probe
must be placed as close as possible to the warmest part of the
external ear canal An incorrectly placed probe could lead to a false
temperature reading

The temperature of the human body varies throughout the day It
can also be influenced by numerous external factors: age, sex, type
and thickness of skin…

ThermoFlash LX-26 User Manual – English V 15 200904 7
ADVANTAGES OF TEMPORAL ARTERY ( TA ) TEMPERATURE
Infrared arterial temperature can be measured using a device
placed on the forehead, in the temporal artery region It has been
demonstrated that this relatively new method of measuring
temperature is more precise than tympanic thermometry and better
tolerated than rectal thermometry
The Thermo Flash LX-26 thermometer has been designed to
produce an instant forehead temperature reading without any
contact with the temporal artery As this artery is quite close to the
surface of this skin and therefore accessible and given the blood
flow is permanent and regular, it allows precise measurement of the
temperature This artery is linked to the heart by the carotid artery
which is directly linked to the aorta It forms part of the main trunk
of the arterial system The efficiency, speed and comfort of taking a
temperature from this area make it ideal compared with other
temperature measurements methods

P RACTICAL CONSIDERATIONS W EN TAKING A TEMPERATURE
-In order to ensure that precise and accurate temperature
measurements are obtained, it is essential that each user has
received adequate information on and training in the temperature
measurement technique when using such a device
-It is essential to remember that although procedures such as
taking a temperature may be simple they must not be trivialised
-Temperature should be taken in a neutral context The patient
must not have undertaken vigorous physical activity prior to

ThermoFlash LX-26 User Manual – English V 15 200904 8
taking his/her temperature and the room temperature must be
moderate
-Be aware of physiological variations in temperature which must
be taken into consideration when evaluating the results:
temperature increases by 0 5C° between 6am and 3pm Women
have a temperature that is higher, on average, by around 0 2C°
Their temperature also varies in accordance with their ovarian
cycle It rises by 0 5C° in the second half of the cycle and at the
early stages of pregnancy
-When sitting, temperature is lower by about 0 3 to 0 4C° than
when standing
OW TO TAKE A TEMPERATURE
Aim at the FORE EAD, over
the right temporal region,
from a distance of about
5cm, press the thermometer’s
measurement button and the
temperature is instantly
displayed
The reliability of the
measurement cannot
be guaranteed if the
temperature is measured over
another part of the body (e g
arm, torso…)
C ONSTRAINTS
Please observe the following before any temperature measurement
to ensure a stable and reliable result:
- Push back hair from the forehead
- Wipe away any perspiration from the forehead
- Avoid any drafts (e g from nasal specs, air conditioning…)
- Allow a 1 minute interval between two measurements
- Each time there is a significant change in the ambient
temperature due to a change in environment, to allow the
Thermo Flash LX-26 to acclimatise to this ambient
temperature for at least 15 minutes before using it

Advice
Temperature reading hampered
by hair, perspiration…
Make sure that there is no
obstruction prior to taking a
temperature
Temperature hampered by an
air flux
Make sure there is no air flux as
this could interfere with the
infrared system
Temperature readings too close
together, the ThermoFlash did
not have the chance to boot
itself
Respect the pause of 15
seconds minimum between two
readings – 1 minute pause is
advised
The measuring distance is too
far
Please respect the measuring
distance (between 5 and 8 cm –
2 in and 3 14 in)
