Important - Braun WelchAllyn ThermoScan Mode D'emploi

Braun ThermoScan
The Braun ThermoScan thermometer has been carefully developed for accurate,
safe and fast human body temperature measurements in the ear. The shape of
the thermometer probe prevents it from being inserted too far into the ear canal
which could perforate the tympanic membrane.
However, as with any thermometer, proper technique is critical to
obtaining accurate temperatures. Therefore, please read all
instructions carefully and thoroughly before using this product.

Important

• Do not expose the thermometer to temperature extremes (below –4 ºF / – 20 ºC
or over 122 ºF / 50 ºC) nor excessive humidity (> 95 % RH).
• The probe window must be kept clean, dry, and undamaged at all times to
ensure accurate measurements. To protect the probe window, always keep the
thermometer in the storage cover while transporting or when not in use.
• This thermometer must only be used with genuine Braun ThermoScan
probe covers.
• To avoid inaccurate measurements, always attach a new, clean probe cover for
each temperature measurement.
How does Braun ThermoScan work?
The Braun PRO 4000 technology reads the infrared energy emitted by the
tympanic membrane and surrounding tissues to determine the patient's
temperature. To help ensure accurate temperature measurements, the sensor
itself is warmed to a temperature close to that of the human body. When the
Braun ThermoScan is placed in the ear, it continuously monitors the infrared
energy until a temperature equilibrium has been reached and an accurate
measurement can be taken. The thermometer displays a clinically accurate, oral
equivalent temperature that has been validated in clinical studies by comparing
IR measurements with the oral readings from afebrile and febrile patients of
various ages.
Why measure in the ear?
Clinical studies have shown that the ear is an excellent site for temperature
measurement because temperatures taken in the ear reflect the body's core
temperature . Body temperature is regulated by the hypothalamus

shares the same blood supply as the tympanic membrane
body temperature are usually seen sooner at the tympanic membrane than at
other sites, such as the rectum, mouth or under the arm.
Advantages of taking temperatures at the ear versus traditional sites:
• Axillary temperature measurements reflect skin temperature which may not
reliably indicate the internal body temperature.
• Rectal temperatures often lag significantly behind internal body temperature
changes, especially at times of rapidly changing temperatures. Also, there is a
risk of cross contamination.
• Oral temperatures are often influenced by eating, drinking, thermometer
placement, breathing through the mouth, or the inability of the person to
close their mouth completely.
