technical field

The invention relates to the technical field of body temperature monitoring, in particular to a LORA-based multi-point body temperature continuous monitoring system.

Background technique

At present, mercury thermometers are mostly used for daily temperature monitoring in hospitals. Medical staff often need to measure each patient on the spot. After the measurement, they need to manually record the temperature. Each mercury temperature measurement takes 5 to 10 minutes. This measurement method has cumbersome steps, long measurement time, heavy workload, manual reading is required, temperature errors exist, and the mercury thermometer is prone to breakage during the measurement process, resulting in mercury pollution. At present, the World Health Organization is implementing the "Global Medical Mercury Elimination Plan". my country's "Minamata Convention on Mercury" has come into effect since August 16, 2017, which clearly stipulates that from January 1, 2026, the production of mercury containing Thermometers and mercury sphygmomanometers. Moreover, the common ear thermometers and forehead thermometers on the market all use infrared non-contact measurement, and the measurement accuracy is low, which cannot meet the clinical needs. Therefore, the means and methods of measuring body temperature need to be transformed and upgraded urgently.
