The liquid crystal forehead thermometer is best used at home.��� In 2012, Healthcare Improvement Scotland produced a technology scoping report that found: Evidence from a range of adult and paediatric patient groups suggests that temporal artery thermometers are insufficiently accurate for clinical use in inpatient settings ATI’s liquid crystal temperature labels use color change to indicate temperatures or temperature ranges. Mon - Fri: 8 AM - 5:30 PM CST Sat: 9 AM - 1 PM CST. 2005 Aug;12(8):1292-300. doi: 10.1016/j.arcped.2005.01.034. The mean rectal temperature was 38.0 +/- 0.91 degrees C; forehead, 37.83 +/- 0.94 degrees C; tympanic, 37.77 +/- 0.95 degrees C, and axillary, 37.71 +/- 0.86 degrees C. Compared to the rectal temperature, all values were significantly lower (p < 0.05). The infrared tympanic thermometer may be a preferable option for the uncooperative patient. Temperature indicators are generally located near food, medical or pharmaceutical products and efficiently monitor that temperatures stay within certain levels. For recording body temperature, several different types of thermometers are used, such as mercury thermometers, digital thermometer, liquid crystal forehead thermometer, and infrared tympanic thermometer . Sensitivity of the three devices was 67-83 per cent in detection of fever and 64-77 per cent in detection of high fever. The comprehensive directory provides access to full contact and ability information for sourcing professionals, engineers and researchers wishing to get information on Thermometers: Liquid Crystal. Variations on user technique, such as holding the scanner too far away from the forehead, also may affect accuracy. However, they are not usually quite as accurate as are electrical devices, and you cannot easily record the temperature value as with electrical devices like thermocouples or RTDs; but portability is a definite advantage for the right application. The earliest paper we found was “An Evaluation of a Plastic Strip Thermometer” which reports “We conclude that the Clinitemp is unacceptable as a substitute for the mercury/glass thermometer.” In the same year, a smaller study (n=134) reported: “Parents who rely on these strips to identify a fever in their children may be misled by an erroneous afebrile reading.”, A 1996 study with 120 patients (20 in each of six age groups: < 1 month, 1 to 5 months, 6 to 11 months, 12 to 23 months, 2 to 14 years, and adults concluded: that previous studies have all used inappropriate methods of analysis….. Forehead strip thermometers are easy to use, but they do not estimate the rectal Temperature as accurately as the axillary Temperature does.”. Color-temperature-response calibration of the TLC is done by subjecting the TLC to … Differences between core and skin temperatures defined the accuracy of liquid-crystal thermography under each study circumstance.

A 2015  systematic review of  75 studies (n = 8682) on the accuracy of Peripheral Thermometers for Estimating Temperature reported that most studies at high or unclear risk of bias. Accuracy in detection of fever was 79 per cent for forehead, 85.5 per cent for tympanic and 84 per cent for axillary thermometry. The Clinitemp identified as febrile nine (28%) of 33 children who had fever verified by a glass thermometer. 2014 Feb;103(2):e80-3. But adults can use any type of fever thermometer -- the only considerations are accuracy and convenience. They can be used to observe how heat flows, and in medical applications they may be used to read body temperature through placement on the forehead.  |  Our wide range of Liquid Crystal thermometer labels change colour as the temperature rises and falls. The main results were: Limitations: High-quality data for some temperature measurement techniques are limited. A clinical appraisal. The liquid crystal forehead thermometer gave the least concordance (limits of agreement -1.14–0.98°C). Forehead, tympanic and axillary temperature differed from rectal temperature by at least 0.5 degrees C in 33.33 per cent, 23.5 per cent and 31.5 per cent of subjects, and at least 1 degrees C in 22 per cent, 1 per cent and 6 per cent of subjects respectively. When a specimen cup is filled with a warm fluid, the heat must be conducted through the cup wall to the outside wall onto which the label is … Presentation.
