Body temperature is one of the important vital signs of the human body. Hypothalamus and temperature receptors monitor the temperature regulation. Normally, the human body will regulate the temperature within the normal body temperature range through its own thermoregulatory system. However, there are many events (anesthesia, surgery, first aid, etc.) in the hospital that will disrupt the thermoregulatory system of the human body, and if not treated in time, it may cause damage to multiple organs of the patient and even lead to death, which requires real-time continuous monitoring of the patient 's body temperature by medical staff.

Under what circumstances, the body temperature probe needs to be used? 

Generally, such as the body temperature measurement of adults and children at home or the simple temperature monitoring of the hospital, we can use mercury thermometer or electronic thermometer to measure the body temperature through the contact with the body surface of the mouth, armpits, rectum, forehead, etc., so as to determine whether the body is in the normal temperature range. 

For surgical patients, ICU patients and some special care patients need more stable and accurate body temperature monitoring, and body temperature probe (body temperature probe is also called medical temperature sensor) can be used in combination with monitor. The body temperature probe is used in combination with the monitor, which can more accurately, safely and comfortably perform continuous body temperature management for the patients, and this body temperature probe plays an increasingly important role in the prognosis period during anesthesia and after perioperative period. 

Because the reusable temperature probe is used for a long time, the accuracy will be reduced and the risk of cross infection will be increased. At present, most ICU wards of many large hospitals or departments requiring real-time monitoring of the patient 's body temperature in China use disposable medical temperature sensor as an important tool for the patient' s body temperature management.

The working principle and advantage of the temperature probe

The temperature sensor is a sensitive element, which is usually composed of one or several high-precision rapid-response thermistors (NTC chips), and it is directly related to the accuracy and response speed of the output temperature. The disposable medical temperature probe composed of this temperature sensor can read the patient 's body temperature within 4 seconds, which is several orders of magnitude higher than the traditional mercury thermometer, and its advantage is quite obvious.

Compared with mercury thermometer and infrared thermometer, medical temperature sensor has the following advantages: 

● shorter reaction time, real-time monitoring; 

● no repeated measurement, reducing the cumbersome work of medical staff and improving the nursing efficiency; 

● the accuracy of measurement is higher, the accuracy of Yixinda body temperature probe can achieve ± 0.01℃ 

● disposable use, no cumbersome disinfection, avoiding cross infection of patients; 

● the core body temperature of patients is monitored, which is more accurate than the body surface temperature;

Disposable medical temperature sensor has been used in combination with monitor at home and abroad for more than 30 years. It is safer, simpler and more sanitary for temperature measurement. It can continuously and accurately provide body temperature data, eliminating the complex procedure of repeated disinfection and avoiding the risk of cross infection between patients. Especially in the operating room, ICU, special care room, real-time, continuous, stable, safe and accurate monitoring of patient body temperature changes is helpful for doctors to confirm the diagnosis, determine the condition and analyze the efficacy, which has very important clinical significance.
