Description

Non-contact intelligent human earplug temperature detector

Technical Field

The utility model relates to the field of temperature monitoring, in particular to a non-contact intelligent human body earplug thermodetector.

Background

Clinically, measuring the body temperature of a patient and observing the change of the body temperature has important significance for diagnosing diseases or judging the prognosis of certain diseases. In the past, clinical common thermometric devices mainly comprise mercury thermometers, electronic thermometers and non-contact infrared thermometers, and the three thermometric devices have the problem that real-time detection cannot be achieved in clinic and need a large amount of manual operation. The first kind of thermometric mercury columns has been out of use in europe, japan, etc. for their safety and metal contamination. The second type of human body thermometry is in-ear thermometry, which is located in the hypothalamus of the human ear, which is the regulatory center of human body temperature, and its blood vessels go through the eardrum region, so the eardrum is also the best position for assessing the true body temperature. The thermometer is directly placed in the ear, the body temperature can be measured in three or two seconds through the thermistor, the structure of the thermometer is generally a pen-type structure, a power supply adopts a miniature button cell, and a circuit structure adopts a traditional temperature sensitive resistor-signal processing circuit-temperature display structure. The third kind of human body temperature measuring technology is infrared temperature measuring technology, which irradiates the exposed parts of human face, hand, etc. with infrared ray to measure the temperature and reflected wave relationship and to measure body temperature in several seconds. The three temperature measurement technologies have several technical problems, one of which is that the battery capacity is very small, the measurement cannot be carried out continuously in real time, and the three temperature measurement technologies are not suitable for the long-time continuous monitoring of patients; errors of two circuit elements easily cause measurement errors, and elements are unstable; thirdly, because the thermometers adopt a power supply circuit, the thermometers cannot be disinfected in a full volume mode, and cannot be used by all people in hospitals and community environments. At present, the latest technology of human body temperature measurement, i, extracts the original text report of Xinhua society: the researchers of the university of Tokyo Japan university of Japan, 3.2019, 14 days of China, of Xinhua society newly invent a 'tablet type' thermometer for internal use, can be discharged out of the body along with excrement, and has been successfully tested on dogs. The news bulletin issued by northeast university of japan teaches that the thermometer for internal use is about 9 mm in diameter and about 7mm in thickness, and has a tablet size of only one piece, and contains a temperature sensor, a micro integrated circuit, and the like, and is externally made of a resin material. It does not use button cell harmful to human body, but uses gastric acid to contact electrode to generate electricity and store it in capacitor, and can measure internal temp. once every 30 min and transmit data. The group has successfully tested this thermometer on dogs, and will next also conduct a human suitability test. It is described that the temperature in the body of a person at rest is one of the important health indicators. When the general thermometer is used for measuring the body surface temperature, the error is large, and the rectal measurement is accurate but inconvenient to operate. In contrast, the disposable oral thermometer is easy to operate and is helpful for early disease discovery. The most accurate mode of medical measurement of the body temperature of a human body is an in-vivo measurement mode, the in-vivo measurement is very limited due to the prior technical barrier and cannot be used as the main clinical application, and hospitals and families can only adopt the body surface temperature measurement for disease prevention, epidemic prevention, prevention and control and temperature measurement.

At present, the technology of measuring the temperature in vivo and body surface still applies the structure of the traditional temperature sensor, the microprocessor and the battery, and the structure of the internal thermometer for measuring the temperature in vivo is also used in the above-mentioned "internal thermometer" of northeast university of japan. The known human body temperature measuring methods cannot simultaneously meet the requirements of real-time measurement of measuring time, wireless communication capacity, direct and accurate measurement of human bodies and flowing and intensive measurement of multiple people.
