II. Intended use
The device is an infrared thermometer intended to measure the forehead temperature of infants and adults without contacting the human body. It can be used by consumers in household environments and doctors in clinics as a reference.
III. Introduction
The JXB-178 Non-contact Infrared thermometer has been developed by using the latest infrared technology. This technology allows temporal artery (TA) temperature to be taken at a distance of about 3cm-5cm away from the forehead. Precise, Instantaneous, and without Contact, the JXB-178 is, up to now, the most suitable thermometer for no risk on temperature measurement. It has been demonstrated that this method of TA temperature measurement is more precise than the tympanic thermometry and better tolerated than rectal thermometry (1). However, as with other types of thermometers, it is essential to use the JXB-178 properly in order to obtain reliable and stable results. You are therefore advised to read this instruction manual and the safety precautions carefully before use. (1)Greenes D, Fleisher G. Accuracy of a Noninvasive Temporal Artery Thermometer for Use in Infants. Arch Pediatr Adolesc Med 2001;155:376.
IV. Precautions before use
The JXB-178 is pre-set at the factory. It is not necessary to calibrate the device when starting it up.
In order to obtain reliable and stable results, you are advised each time there is a significant change in the ambient temperature due to a change in environment, to allow the JXB-178 to acclimatize to this ambient temperature for 15 to 20 minutes before using it. It is important to allow 3-5 seconds intervals between two measurements.
V. Operating principle
All objects, solid, liquid, or gas, emit energy by radiation. The intensity of this energy depends on the temperature of the object. The JXB-178 infrared thermometer is, therefore, able to measure the temperature of a person by the energy the person emits. This measurement can be taken thanks to an external temperature probe on the device which permanently analyses and registers the ambient temperature. Therefore, as soon as the operator holds the thermometer near the body and activates the radiation sensor, the measurement is taken instantly by the detection of the infrared heat generated by the arterial blood flow. Body heat can therefore be measured without any interference from the heat of the surrounding environment.

THE DIFFERENT METHODS OF TEMPERATURE MEASUREMENT

Core temperature
Core temperature is the most precise measurement and involves measuring the temperature in the pulmonary artery by means of a catheter equipped with a thermal probe that can read the temperature in situ. The same method is employed for probes measuring the oesophageal temperature. However, such invasive temperature measurement methods require specific equipment and expertise.

Rectal thermometry
Rectal temperature adjusts slowly in comparison to the evolution of the body’s internal temperature. It has been demonstrated that rectal temperature remains raised long after the internal temperature of the patient has started to drop and vice versa. Furthermore, rectal perforations have been known to occur as a result of this method and without appropriate sterilization techniques, rectal thermometry can spread germs often found in feces.

Oral thermometry
Oral temperature is easily influenced by recent ingestion of food or drinks and by breathing through the mouth. To measure oral temperature, the mouth must remain closed and the tongue lowered for three to four minutes which is a difficult task for young children to accomplish.

Axillary (armpit) temperature
Although it may be easy to measure axillary temperature, it has been proven that it does not provide an accurate measurement of the child’s internal temperature. To make this type of temperature, the thermometer must be wedged tightly over the axillary artery. Despite the low sensitivity and relative inaccuracy of axillary temperature in detecting fever, this method is recommended by The American Academy of Pediatrics as a screening test for fever in newborns.

Tympanic thermometry
In order to obtain a precise temperature reading, good command of the measurement technique is required. The thermometer probe must be placed as close as possible to the warmest part of the external ear canal.

The temperature of the human body varies throughout the day.

It can also be influenced by numerous external factors: age, sex, type, and thickness of skin…
Advantages of temporal artery (ta) temperature Infrared arterial temperature can be measured using a device placed on the forehead, in the temporal artery region. It has been demonstrated that this relatively new method of measuring temperature is more precise than tympanic thermometry and better tolerated than rectal thermometry. The JXB-178 thermometer has been designed to produce an instant forehead temperature reading without any contact with the temporal artery. As this artery is quite close to the surface of this skin and therefore accessible and given the blood flow is permanent and regular, it allows precise measurement of the temperature. This artery is linked to the heart by the carotid artery which is directly linked to the aorta. It forms part of the main trunk of the arterial system. The efficiency, speed, and comfort of taking a temperature from this area make it ideal compared with other temperature measurements methods.

Practical considerations when taking a temperature

– In order to ensure that precise and accurate temperature measurements are obtained, it is essential that each user has received adequate information on and training in the temperature measurement technique when using such a device.
– It is essential to remember that although procedures such as taking a temperature may be simple they must not be trivialized.
– Temperature should be taken in a neutral context. The patient must not have undertaken vigorous physical activity prior to taking his/her temperature and the room temperature must be moderate.
– Be aware of physiological variations in temperature which must be taken into consideration when evaluating the results: temperature increases by 0.5°C between 6 am and 3 pm. Women have a temperature that is higher, on average, by around 0.2°C. Their temperature also varies in accordance with their ovarian cycle. It rises by 0.5°C in the second half of the cycle and at the early stages of pregnancy.
– When sitting, the temperature is lower by about 0.3°C to 0.4°C than when standing.

How to take a temperature

Brrcom Non-Contact Infrared Thermometer JXB-178 User Manual  & troubleshooting 9

Aim at the middle of the forehead, from a distance of about 1.2in-2.0in, press the thermometer’s measurement button and the temperature is instantly displayed.

Brrcom Non-Contact Infrared Thermometer JXB-178 User Manual  & troubleshooting 10The reliability of the measurement cannot be guaranteed if the temperature is measured over another part of the body (e.g.arm, torso…)

Constraints

Please observe the following before any temperature measurement to ensure a stable and reliable result:
– Push back the hair from the forehead.
– Wipe away any perspiration from the forehead.
– Avoid any drafts (e.g. from nasal specs, air conditioning…)
– Allow a 3-5 seconds interval between two measurements.
– Each time there is a significant change in the ambient temperature due to a change in environment, to allow the JXB-178 to acclimatize to this ambient temperature for at least 15 minutes before using it.
