Infrared Ear thermometers are developed using the latest infrared technology to develop. digital infrared ear thermometer can measure your temperature quickly (1 second) and easily by inserting the tip into your ear. Great for testing potential SARS patients.

Principle:
An infrared (IR) thermometer contains an optical sensor, usually a thermopile, which can detect the infrared emissions from any hot object. The magnitude and spectrum of infrared energy emitted depends on:
a.) internal temperature of the body
b.) temperature of the thermometer, which is also radiating IR energy
c.) emissivity, which describes the efficiency of the surface for radiating electromagnetic radiation and is a dimensionless number between 0 (smooth shiny surface) and 1 (dark rough surface)
d.) filtering effect of optical components, including the probe cover.
Infrared ear thermometers are designed to sense the temperature of the tympanic membrane within the ear. The measured temperature is an average across the visualised area. The field of view may encompass adjacent ear structures, approximately 2 Calsius cooler than the tympanic menbrane (typically 37.3 Calsius). An instrumentation offset is usually applied which incorporates information about the thermometer's temperature and filtering effect of the optical components. Some devices also try to correct for the effect of averaging( making assumptions about the relative size of the tympanic membrane in the field of view.)
Forehead thermometers repeatedly sample the skin temperature seeking peak values, caused by the presence of the temporal artery lying under the surface. Inftrumentation offset values and physiological offset values are then applied to predict the temperature at another site, usually oral. All these devices use computational software to rapidly predict the temperature but the algorithms will vary between different types as they are based on their own clinical trials.
Our advice on clinical use
The key issues covered in the user instructions for infrared eat thermometers are:
1.) Check the ear canal is clean, dry and normal in apparence and is not obstructed or containing vernix, inflammation, blood or excessive earwax. Bote the general angle of the ear canal.
2.) Ensuring the thermometer lens is clean.
3.) Straighten the ear canal, giving a clear view of the eardum and position the thermometer head so the sensor will be directed at the tympanic menbrance and not cooler eat structures. For children <1 year the ear lobe should be pulled straight back. For older patients pull the ear lobe up and back. Incorrect placing can give falsely low temperature readings.
4.) Failing to seal the ear canal opening may result in a lower reading.
5.) Do not use excessive force to insert the probe into the ear as this may injure the ear canal or ear drum.
6.) The patient should not exercise or talk during temperature taking.
7.) Do not take a patient reading within 30 minutes of a bath/shower or swimming.
8.) Always wait two minutes before repeating a measurement in the same ear.
9.)Always compare measurements from the same ear.
10.)Using the maximum of three repeated measurements is recommended for infants less than 100days old, children under three years with compromised immune sustem and when the user is learning to use the thermometer.
