Description
Technical field
This utility model relates to a kind of bluetooth clinical thermometer, is based on bluetooth microcontroller, thermometric thermometer, it may be achieved the real-time monitoring to body temperature, relates to electronic clinical thermometer, armarium industry field.
Background technology
Human body keeps normal body temperature, is to ensure that the essential condition that metabolism and vital movement are normally carried out.Therefore the monitoring of body temperature, analysis are had certain medical significance, can be used for judging, positioning the sign state that human body is different.Body temperature is usually the temperature of body interior thoracic cavity, abdominal cavity, nervus centralis, has and is called core temperature, is characterized in relatively stable and relatively skin temperature is high.Instrument and classification that current measurement of bldy temperature uses 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 some pharmacies are just commercially available mercury clinical thermometer.But considering the hydrargyrum harm in mercury clinical thermometer, it was all taken denial measure by many countries, for instance as far back as 1992, Sweden has just forbidden selling all mercuric armarium.Not prohibitting the use of 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, within 2008, the whole nation produces mercury clinical thermometer consumption hydrargyrum 109.25 tons, is equivalent to 218.5 hundred million standards mercury use containing hydrargyrum energy-saving lamp.Domestic annual 1.2 hundred million the mercurous clinical thermometers that about produce, and the hydrargyrum that China regards refuse process every year because mercury clinical thermometer breakage just has more than 10 tons.
Electronic clinical thermometer is by temperature sensor, liquid crystal display, button cell, special IC and other electronic devices and components composition.Body temperature can be measured rapidly and accurately, compared with traditional mercury glass clinical thermometer, there is convenient reading, the measurement time is short, certainty of measurement is high, the advantage can remembered and have buzzing to point out, and especially electronic clinical thermometer is without hydrargyrum, human body and surrounding is harmless, it is particularly suitable for the occasion such as family, hospital and uses.
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, as long as general one second acquisition time, just can record accurate body temperature from ear.During measurement, temperature measuring head is inserted auditory meatus, continue one second according to the thermometric of upper end, so that it may read from liquid crystal display screen and be accurate to the accurate body temperature of one after base point.Non-contact infrared body temperature meter is most commonly that volume temperature rifle, can realize the measurement to human body temperature at a distance.Only by alignment probe forehead, measurement button need to be pressed, only within 2 to 3 seconds, just can obtain measurement data, be suitable for anxious severe case, old man, infant etc. and use.But at the initial stage of use, user is not owing to being familiar with this mode of operation, it is possible to can obtain several different measurement data, namely actual measurement maximum is wanted data in general.
It addition, disposable type clinical thermometer, temperature-sensitive film, it is all the temperature characterisitic utilizing thermo-responsive chemical material, and under different temperatures, color difference realizes temperature survey, but generally can only realize tentatively judging that body temperature is whether within normal range, it is impossible to accurately measure body temperature.
In sum, in above measurement device, method, before at present, mercury clinical thermometer, electronic clinical thermometer two kinds use wide at medical treatment, domestic, mainly have some superiority with its certainty of measurement, cost.But both measures instrument cannot realize the real-time measurement to body temperature, in medical industry, rely primarily on that medical personnel carry out collection in worksite, the mode of manual entry carries out the collection of information.Therefore along with electronic technology, mobile terminal function abundant, a kind of realize body temperature monitor in real time, the electronic clinical thermometer demand of data analysis also more and more strong.
Summary of the invention
The technical problems to be solved in the utility model is that following three points: (1) can realize in real time the accurate measurement of body temperature automatically；(2) analysis to temperature data, storage function can be realized；(3) small product size is small and exquisite, when carrying out temperature survey collection, does not affect the normal operation of tested personnel, study.
For solving above-mentioned technical problem, the techniques below scheme that the design adopts:
A kind of bluetooth clinical thermometer, it includes 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 equipment 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, simultaneously completes data management, transmission automatically.Arranging under automatic drainage pattern corresponding, system can realize automatic collection.
CC2541 is the real sheet loading system solution of a power optimization applied for low energy consumption and 2.4GHz Bluetooth communication, and the outstanding performance of Bluetooth RF transceiver and the enhancement mode 8051MCU of an industrywide standard, In-System Programmable flash memories, 8kBRAM and other functional characteristic and peripheral hardware are combined by CC2541.CC2541 is highly suitable to be applied for needing the system of super low energy consumption.It is containing 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 within the scope of 35.5 ~ 42 DEG C of measurements, clinical thermometer indicating value allowable error is ± 0.1 DEG C.Therefore according to temperature measurement accuracy requirement, selecting 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 can directly output it 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, intend choosing and select button cell, need 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) interface of follow-up other functions of increase it is available for.
In sum, clinical thermometer of the present utility model passes through monolithic CC2541 microcontroller, it may be achieved temperature signal collection, function of Bluetooth communication, and be transmitted by bluetooth, the function of real-time daytime measurement can be realized, and be analyzed by special-purpose software, compensate for the deficiency of tradition temperature monitoring.
