Peak Select System
The Genius™ 2 Tympanic Thermometer and Base uses the patented Peak Select System. This system is well known from our
Genius™ Thermometer. It reduces technique errors by taking multiple readings and automatically selecting the most accurate
temperature for display. Whereas the Genius™ only used 32 readings for Peak Select, the new and improved Genius™ 2 Tympanic
Thermometer and Base uses 100 readings.
Equivalence Modes
Genius™ 2 Tympanic Thermometer and Base is an ear canal thermometer for neonates, newborns, children, and adults.
Prior to the introduction of tympanic thermometry, patient temperatures were measured in the mouth (oral), in the rectum
(rectal), or in special cases with an indwelling Swan-Ganz™* catheter (core). If a patient's temperature was measured
simultaneously with each of these methods, different absolute temperatures would be obtained. The Genius™ 2 Tympanic
Thermometer and Base compensates for the average difference in temperature at each of these sites by adjusting the
displayed temperature.
A checker / calibrator is available for this device. The device should be checked if it is dropped or if it is stored at less than -25°C or
above 55°C.
"ASTM laboratory accuracy requirements in the display range of 37 to 39°C (98 to 102°F) for Infrared thermometers is ± 0.2°C (±
0.4°F), whereas for mercury-in-glass and electronic thermometers, the requirement per ASTM Standards E 667-86 and E 1112-86 is
± 0.1°C (± 0.2°F). "
The following equivalence modes are available on the Genius™ 2 Tympanic Thermometer and Base. Data is available from
Covidien llc on request.
Ear: In ear (EAR) mode, the display will indicate the absolute temperature without adjustment.
Oral: In oral (ORL) mode, the tympanic temperature is adjusted to display an oral temperature equivalent.
Oral Mode = Ear Mode + 0.60°C.
Core: In core (CORE) mode, the tympanic temperature is adjusted to display the core temperature equivalent.
Core Mode = Ear Mode + 1.04°C.
Rectal: In rectal (REC) mode, the tympanic temperature is adjusted to display the rectal temperature equivalent.
Rectal Mode = Ear Mode + 1.16°C.
Probe Covers
The Genius™ 2 Tympanic Thermometer and Base utilizes a single use disposable probe cover during temperature measurement.
The probe cover was designed especially for use with the Genius™ 2 Tympanic Thermometer and Base. The use of probe covers
produced by any company except Covidien llc will result in erroneous temperature measurement. In order to aid in infection
prevention and control, always install a new probe cover prior to taking a temperature. The probe covers are contained in a
cassette that is located in the thermometer base. To load a probe cover on the thermometer, firmly insert the probe tip into the
probe cover. When installed on the thermometer, the probe cover membrane should be smooth with no holes, tears, or wrinkles.
After the patient temperature has been taken, eject the probe cover by pressing the eject button and then dispose of properly.
