Comparing Principle and Advantages between Disposable Temperature Probe and Mercury Thermometer
The disposable temperature probe generally uses Negative Temperature Coefficient （NTC） thermistor as the temperature sensor, the change of temperature will affects the change of resistance.
When a constant current passed in the temperature measurement circuit, the change of the temperature sensor resistance will be directly in the form of voltage changes, and then the generated signals are amplified and transformed by software, that’s the temperature data.
Mercury thermometers are the principle of using mercury to expand. When the temperature rises, the mercury rises and the temperature date does not fall on its own without exerting external forces, it’s easy for us to record the temperature degree.
Due to the temperature data are greatly influenced by ambient temperature, so should be avoided due to tilt the quilt, the patient raised his arm and so on influence local temperature drop, thus affect the detected temperature readings.
The temperature probe of Exsense-Medical can continuously and dynamically reflect the patient's actual body temperature. In particular, some patients who are under anesthesia and high fever have not been able to take the temperature for many times.
The disposable temperature probe can reduce the temperature deviation and the negative psychological impact of the patient, and it can also reduce the workload of the nurses.
If the placement of mercury thermometers not appropriate, sometimes the thermometer may be difficult to contact with the skin. But the disposable temperature probe can effectively avoid this disadvantage, and it is not easy to be affected by the movement of the hand.
We also found that the temperature data monitored by the mercury thermometer had to be placed for 10 minutes before record. The disposable temperature probe reflects the real-time temperature, which reduces unnecessary waiting time, and then the medical workers can provide more timely treatment for patients.
