The Welch Allyn™ Model 9020 tympanic thermometer incorporates infrared optics with advanced microelectronics to quickly and efficiently register tympanic membrane-derived temperatures.
All matter emits thermally-generated electromagnetic waves. As the temperature of an object increases, it increased radiates infrared energy (heat rays) at amplitudes and wavelengths corresponding to its temperature.
The infrared sensing system of the 9020, co-developed with NASA’s Jet Propulsion Laboratory, employs state-of-the art technology to measure infrared radiation within the ear canal. The thermometer calculates the patient’s temperature from the highest level of infrared energy detected.
Clinical studies indicate that the temperature of the tympanic membrane correlates well with core body temperature.
The ergonomically-designed 9020 offers the most noninvasive approach to determine body temperature.
Tympanic site measurements enhance patient comfort and avoid contact with mucous membranes, substantially minimizing the risk of cross-contamination.
In addition, tympanic temperatures are not affected by patient-specific variables such as respiration, eating, drinking, and smoking.
The 9020 is ideal for intubated patients and others who cannot have their temperatures taken orally.
