As one of the medical equipment that saves the life of patients with respiratory failure and assists respiratory function, the precise control of airway gas temperature by medical breathing machine is related to the safety of diagnosis and treatment and rehabilitation effect of patients. To ensure that patients receive humid air at the appropriate temperature, the medical breathing machine is equipped with EXSENSE high-sensitivity NTC thermistor to help improve treatment effectiveness.

Combined with the structural design of medical breathing machine and temperature measurement requirements, the installation positions of EXSENSE thermistors are mainly concentrated in two areas. First, the core installation area is inside the heating humidifier, and the NTC is usually close to the heating plate of the humidifier to monitor the heating temperature of the humidification liquid. Secondly, thermistor is installed in the airway pipeline to monitor the temperature of the output gas in real time. Specifically, after the EXSENSE medical NTC thermistor senses the temperature, its resistance value will change accordingly, and the voltage at the voltage divider will change accordingly. The main control unit of the medical breathing machine collects the voltage signal through the ADC and calculates the accurate temperature data. When the monitoring temperature deviates from the preset threshold, the main control unit immediately adjusts the heating power or activates the heat dissipation mechanism to avoid low-temperature dry gas irritation of the patient's respiratory tract or high-temperature gas burning the airway mucous membrane, which fully reflects the importance of EXSENSE thermistors in ensuring the safe and stable work of medical breathing machine.

As the "temperature guardian" in medical breathing machine, EXSENSE medical NTC thermistor can improve breathing machine operation reliability and accurate temperature monitoring with their excellent electrical characteristics:

1. High-accuracy temperature measurement is the basis of treatment safety

The accuracy requirement for temperature monitoring in medical breathing machine is much higher than those in the industrial and consumer electronics fields, the ± 0.5% tolerance of EXSENSE medical NTC thermistor is the key to accurate temperature sensing. This feature can avoid the temperature control adjustment deviation caused by the temperature measurement error of the breathing machine, so that the output gas temperature is always stable in the preset range, ensure the matching of the humidification effect and gas humidity, help the medical breathing machine achieve effective diagnosis and treatment auxiliary functions.

2. Small-dimension encapsulating is the prerequisite for design optimization

With the development of medical technology, breathing machine is developing in the direction of miniaturization, portability, and high-density integration, especially home breathing machine and emergency transport breathing machine, which put forward extremely high requirements for the size of internal components. EXSENSE Medical NTC thermistor has a small temperature sensing head and can be easily embedded in breathing machine heating humidifier, airway line interface, etc., without occupying too much design space, providing support for the integration and optimization of other breathing machine components. In addition, the small-dimension EXSENSE thermistor has a faster thermal response speed, which can obtain temperature changes faster than conventional NTC, further improving the regulation efficiency of the breathing machine temperature control system and helping the equipment achieve efficient and stable operation.

EXSENSE medical NTC Thermistor is the core sensing carrier for temperature monitoring of medical breathing machine, and its highly sensitive temperature collection capability is the cornerstone of the normal operation of the temperature control system. The application of EXSENSE medical NTC thermistors in medical breathing machine not only promotes the upgrading of its temperature control technology, but also builds a solid safety defense line for the clinical application of breathing machine, which is of great significance for improving the therapeutic effectiveness of medical breathing machine.
