Wearable body temperature monitoring intelligent temperature sensor and monitoring method thereof

Abstract

The invention provides a wearable body temperature monitoring intelligent temperature sensor and a monitoring method thereof. The sensor comprises an MCU control unit, a temperature signal processingunit, a temperature probe group switch unit, a temperature probe group, a voltage dividing unit, a display unit and a voltage stabilizing unit; the temperature probe group comprises multiple NTC temperature probes and a fixing device used for fixing the temperature probes, and the NTC temperature probes are fixed to the fixing device according to a certain order, and the temperature probe group isplaced under the human axilla to measure the body temperature; the MCU control unit is used for controlling the temperature probe group switch unit, driving the probes in the temperature probe groupin sequence, and collecting temperature probe signals of all positions in sequence; the voltage stabilizing unit is used for providing precise voltage, temperature probe group signals are calculated through MCU, and a temperature value of a monitored body is obtained and displayed in the display unit. Accordingly, the temperature measurement precision is high, the heating up time is short, the temperature compensation function is achieved, a temperature measurement value is not affected by the environment temperature, and whether or not the intelligent temperature sensor makes good contact with the monitored body can be accurately judged.

Description

technical field [0001] The invention relates to the technical field of wearable body temperature monitoring, in particular to an intelligent temperature sensor for wearable body temperature monitoring and a monitoring method thereof. Background technique [0002] Body temperature is one of the important vital sign parameters. According to the national clinical medical care requirements, all hospitalized patients must measure body temperature parameters on time. At present, clinical body temperature measurement mainly uses traditional mercury thermometers for manual measurement and recording. This method not only consumes a lot of manpower, and cannot realize large-scale real-time monitoring, but also has great risks in using mercury thermometers, which is easy to cause cross-infection, and does not meet the technological requirements of high efficiency, energy saving, hygiene, and safety. On October 11, 2013, the World Health Organization in Geneva and Health Care Without H...

Problems solved by technology

Relevant studies believe that infrared ear thermometers have the advantages of safety and convenience, but after investigation and comparison of the readings of 3 different brands of infrared ear thermometers at home and abroad with mercury thermometers during the same period, it was found that the 3 brands of infrared ear thermometers were in the same period of time. After two months of clinical use, there will be an error of 0.3~0.5°C, which leads to low trust in the measurement results for patients and their families

The monitor carries a temperature monitoring probe, which is expensive. One end of the temperature probe is connected to one end of the monitoring module, which restricts the patient's activities and is not conducive to the recovery of the patient's condition.

[0004] The temperature measurement value of the existing wearable body temperature monitoring equipment is affected by the ambient temperature and cannot be compensated according to the actual situation

In addition, since the wearing position and wearing comfort (tightness) will affect the measurement accuracy and cause measurement errors, it will affect the clinician's accurate judgment of the patient's actual body temperature, which in turn will affect the formulation of treatment measures and treatment plans.

In addition, due to the existing products, it is easy to cause the product and the measured human body to not fit tightly during the wearer's activities, thereby causing certain measurement errors; at the same time, due to the characteristics of the NTC thermistor itself, its heating time is relatively slow
