Description
Technical field
The present invention relates to a kind of bluetooth clinical thermometer, be based on bluetooth microcontroller, thermometric thermometer, the Real-Time Monitoring to body temperature can be realized, relate to electronic clinical thermometer, armarium industry field.
Background technology
Human body keeps normal body temperature, is the essential condition ensureing that metabolism and vital movement are normally carried out.Therefore to the monitoring of body temperature, analyze there is certain medical significance, can be used for the sign state judged, location human body is different.The temperature of body temperature normally body interior thoracic cavity, abdominal cavity, nervus centralis, has and is called core temperature, is characterized in relatively stable and comparatively skin temperature is high.The instrument that current measurement of bldy temperature uses and classification can be divided into following several:
Mercury clinical thermometer or glass thermometer, it is made up of glass, inside has the mercury column of satellite temperature rise.Mercury clinical thermometer is widely used at medical field and average family, and mercury clinical thermometer just can have been bought by some pharmacies.But consider the hydrargyrum harm in mercury clinical thermometer, many countries all take denial measure to it, such as, as far back as 1992, Sweden has just forbidden selling all mercuric armarium.Do not prohibit the use mercury clinical thermometer in China, mercury clinical thermometer is widely used at medical field and average family.Data from medical device industry association of China show, and within 2008, the whole nation produces mercury clinical thermometer consumption hydrargyrum 109.25 tons, is equivalent to the mercury use of 218.5 hundred million standards containing hydrargyrum energy-saving lamp.Domestic annual approximately production 1.2 hundred million mercurous clinical thermometers, and China regards refuse process every year hydrargyrum because mercury clinical thermometer is damaged just has more than 10 tons.
Electronic clinical thermometer is by temperature sensor, and liquid crystal display, button cell, special IC and other electronic devices and components form.Body temperature can be measured rapidly and accurately, compared with traditional mercury glass clinical thermometer, there is convenient reading, Measuring Time is short, certainty of measurement is high, can remember and the advantage having buzzing to point out, and especially electronic clinical thermometer is not containing hydrargyrum, to human body and surrounding harmless, be particularly suitable for the occasion such as family, hospital and use.
Infrared thermometer can be divided into again contact infrared thermometer and non-contact infrared body temperature meter.Contact clinical thermometer common are ear temperature meter, volume temperature meter, if general one second acquisition time, just can record accurate body temperature from ear.During measurement, temperature measuring head is inserted auditory meatus, the thermometric according to upper end continues a second, just can be accurate to the accurate body temperature of after base point one from liquid crystal display screen reading.Non-contact infrared body temperature meter is modal is volume temperature rifle, can realize the measurement to human body temperature at a distance.Only by alignment probe forehead, measurement button need be pressed, only just can obtain measurement data 2 to 3 seconds, be applicable to the uses such as anxious severe case, old man, infant.But at the use initial stage, user, owing to not being familiar with this mode of operation, may obtain several different measurement data, namely survey maximum is in general wanted data.
In addition, disposable type clinical thermometer, temperature-sensitive film, it is all the temperature characterisitics utilizing thermo-responsive chemical material, and under different temperatures, color difference realizes temperature survey, but generally can only realize tentatively judging body temperature whether within normal range, cannot Measurement accuracy body temperature.
In sum, in above measurement device, method, at present, mercury clinical thermometer, electronic clinical thermometer two kinds use comparatively extensive at medical treatment, domestic, mainly have some superiority with its certainty of measurement, cost.But these two kinds of gauges cannot realize the real-time measurement to body temperature, in medical industry, mainly rely on the collection that medical personnel carry out collection in worksite, the mode of manual entry carries out information.Therefore along with electronic technology, mobile terminal function abundant, a kind of realize body temperature Real-Time Monitoring, data analysis electronic clinical thermometer demand also more and more strong.
Summary of the invention
The technical problem to be solved in the present invention is just following 3 points: (1) can realize the accurate measurement of body temperature automatically in real time; (2) analysis to temperature data, memory function can be realized; (3) small product size is small and exquisite, when carrying out temperature survey collection, does not affect the normal work of tested personnel, study.
For solving the problems of the technologies described above, the following technical scheme that the design adopts:
A kind of bluetooth clinical thermometer, it comprises housing, and housing is built-in with the microcontroller of radio communication function, and temperature sensor is connected with the microcontroller of radio communication function;
The client modules of mobile device is connected by wireless blue tooth signal with microcontroller.
Described temperature sensor is LMT70 type temperature sensors of high precision.
The microcontroller of described radio communication function is CC2541 microcontroller.
Microcontroller is powered by button cell.
Clinical thermometer indoor design has 16 CC2541 microcontrollers, and as master controller, the measurement of management and actuation temperature sensor, completes data management, transmission simultaneously automatically.Correspondence automatic drainage pattern is set under, system can realize automatic collection.
CC2541 is a real sheet loading system solution of power optimization for low energy consumption and the application of 2.4GHz Bluetooth communication, and the enhancement mode 8051MCU of the outstanding performance of Bluetooth RF transceiver and an industrywide standard, In-System Programmable flash memories, 8kBRAM and other functional characteristic and peripheral hardware are combined by CC2541.CC2541 is applicable to the system being applied to needs super low energy consumption very much.It contains 12 analog-digital converters (ADC) of 8 passages and configurable resolution, for the signals collecting of temperature sensor.
In GB " JJF1226-2009 " to the required precision of clinical thermometer in 35.5 ~ 42 DEG C of measuring ranges, clinical thermometer indicating value allowable error is ± 0.1 DEG C.Therefore according to temperature measurement accuracy requirement, select temperature-measuring element LMT70, its certainty of measurement is ± 0.05 ° of C(representative value within the scope of 20 ° of C to 42 ° of C).Its output signal is analog voltage signal, and output characteristics is-5.19mV/ DEG C, and because CC2541 is built-in with 12 bit pattern transducers, the analog digital conversion port that therefore directly can be outputed signal access CC2541 carries out data acquisition.
Power Management Design, because clinical thermometer belongs to Wearable product, for improving security performance, the operating voltage range of parametric device, intending choosing and selecting button cell, needing periodic replacement, as 90 days change once (every day works 8 hours).
Design realization has following functions: (1) display gathers the essential information of client: sex, age, menstrual cycle, childbearing history etc., and product is main in the face of women; (2) temperature data (24 hours, 1 month, 2 months) in specific period is shown; (3) some anomalous body temperature value, abnormal menstruation situation are reported to the police; (4) information stores, uploads, downloads; (5) can for the interface of follow-up other functions of increase.
In sum, clinical thermometer of the present invention, by monolithic CC2541 microcontroller, can realize temperature signal collection, function of Bluetooth communication, and transmitted by bluetooth, the function of real-time daytime measurement can be realized, and analyzed by special-purpose software, compensate for the deficiency of traditional temperature monitoring.
