[Development and application of T-type thermocouple acupoint thermometer].

To address the limitations of existing acupoint temperature measurement, such as susceptibility to environmental interference, inability to perform dynamic monitoring, and invasive operation, a non-invasive acupoint thermometer based on T-type thermocouple has been developed. The instrument consists of multi-channel data collector,miniature thermocouple sensor, temperature-sensitive patch, and Toprie data processing software, offering the advantages including long-term dynamic monitoring of multiple acupoints, stable, rapid and accurate data acquisition, non-invasive portability, and ease of operation. Based on the Seebeck effect, the instrument uses a T-type thermocouple with the diameter ≤1 mm and thermal equilibrium time ≤1 s as the temperature sensing element. It enables long-term dynamic monitoring of multiple acupoints, thereby providing the objective quantitative data for diagnosis of traditional Chinese medicine. With the aid of miniaturization and wireless transmission technologies, the instrument is expected to be extended to clinical application scenarios such as chronic disease management, sports medicine monitoring, and health intervention of"preventive treatment of disease" in traditional Chinese medicine.
