The core of the medical heating blanket is to maintain high-precision temperature monitoring and temperature protection through the EXSENSE medical NTC chip, so that the patient's body temperature can be stabilized within a safe range and prevent abnormal body temperature in perioperative period. Therefore, EXSENSE medical bare chips not only serve as temperature sensors in medical heating blanket, monitoring the temperature of heating blanket and patient skin in real time, but also serve as safety protection components to prevent the risk of overheating.

Patient’s stable body temperature is crucial for prognosis, and medical heating blanket mainly maintains patient’s normal body temperature through active heating. Multiple NTC chips are arranged in different heating areas of the heating blanket to measure the patient's body temperature. Then, this signal is stably fed back to the temperature data acquisition module of the controller through the transmission wire. The controller compares and analyzes the collected temperature data in real time according to the preset temperature threshold, and when the patient's abnormal body temperature changes are detected, it can respond in time and quickly adjust the temperature of the heating blanket, so that the patient's body temperature can be kept within the appropriate range.

The EXSENSE bare chips in the medical heating blanket are also the key components of the over-temperature protection of the medical heating blanket. When the junction temperature during the operating of heating blanket exceeds the safety critical value, the NTC resistance value changes sharply. This signal will quickly trigger the over-temperature alarm protection module of controller, alerting medical staff in time to avoid the risk of burns and equipment damage caused by overheating.

Whether it is the temperature monitoring of medical heating blanket or the over-temperature protection of patient, they all rely on the outstanding electrical characteristics of the EXSENSE high-accuracy NTC chip:

1. High accuracy to ensure the precision and consistency of temperature measurement of medical heating blanket

From the patient's point of view, medical heating blanket can provide double protection for patient safety with the assistance of high-accuracy bare chips. This is because if the heating blanket has "underheating", it cannot effectively maintain the patient's body temperature, which will lead to hypothermia and increase the risk of surgery; "Overheating" may directly cause burns to the patient. EXSENSE high-accuracy NTC accurately measures temperature to avoid such dangerous situations. From the perspective of medical heating blanket operation, accurate temperature data provide a reliable basis for its controllers. When the NTC chip accurately feeds back the temperature signal, the controller can better adjust the heating power and time based on these data, thereby improving the response speed of the temperature control system and ensuring the efficient operation of the heating blanket throughout the entire working process.

2. Fast response, improve the temperature control response speed and dynamic adaptation ability of medical heating blanket

During the perioperative period, the patient's body surface temperature is prone to fluctuations due to surgical operations, environmental changes and other factors. When the patient's local body temperature drops due to exposure to the surgical area, the fast response of the EXSENSE bare chip quickly captures this temperature change and transmits the signal to the controller. After receiving the signal, the controller immediately issues instructions to the heating module, adjusts the output power in time to quickly increase the temperature, realizes dynamic adaptation to temperature changes, and effectively avoids the continuous decrease of the patient's body temperature.
