INTRODUCTION 1
About the System
This manual is a guide for using the CORE•CHECK
®
Tympanic
Thermometer System Model 2090. The CORE•CHECK
®
Thermometer is designed to measure infrared energy emitted
from the tympanic membrane. Infrared energy is generated by
the vibration and movement of molecules in all matter. As
temperature increases so does molecular activity, causing an
increase in the radiation of infrared energy.
Infrared energy emitted from the tympanic membrane in the ear
canal provides an excellent measurement of the body's core
temperature. The blood supply for the tympanic membrane is
common with the hypothalamus, the area of the brain that
regulates body temperature.
The CORE•CHECK
®
Thermometer is positioned in the external
auditory canal. The thermometer senses infrared radiation
emitted from the surface of the tympanic membrane and
surrounding tissue. This reading is quickly processed through
the CORE•CHECK
®
Thermometer technology to provide an
accurate measurement of core body temperature.
The CORE•CHECK
®
Tympanic Thermometer System includes
the thermometer, Probe Cover Dispenser - Model 2992, Home
Base - Model 2993, and Probe Cover Bracket - Model 2994. The
thermometer uses ALARIS Medical Systems
®
Disposable Probe
Covers, Model P90.
For additional information, contact your ALARIS Medical
Systems
®
representative.
