Abstract
The invention relates to an ear thermometer capable of fast measuring and a measuring method thereof. The ear thermometer comprises an infrared ear temperature detection unit, a control unit, a display unit and a signal conversion unit, wherein the control unit and the display unit are respectively connected with a microprocessor; the infrared ear temperature detection unit is connected with the microprocessor by the signal conversion unit; the microprocessor is also in connection with an ambient temperature detection unit; the ambient temperature detection unit periodically detects the temperature of the external environment and stores the temperature information of external environment in order to compensate for the influence of the temperature of the external environment on the ear temperature detected by the infrared ear temperature detection unit through the processing of the microprocessor. When in measurement, the ear thermometer does not need to separately measure the temperature of external environment again before measuring the ear temperature every time, thereby being capable of measuring the ear directly and continuously, greatly reducing the waiting time for each measurement clearance, effectively improving the efficiency of ear temperature measurement and being more beneficial to use.
Description
Technical field
The present invention relates to a kind of body temperature measuring device and technology thereof, particularly a kind of quick measurement ear thermometer and measuring method thereof.
Background technology
Ear thermometer is a kind of contactless body temperature measuring device, its measuring principle is according to blackbody radiation theory, the radiating infrared spectrum difference of object of different temperatures, by measuring the infrared spectrum that tympanum gave off, utilize infrared ear temperature measurement unit to come take temperature, and convert numerical value to by pico computer and show.The hypothalamus that is arranged in human hypothalamic is being undertaken and is being regulated human body heat that produces and the heat that distributes and keep equilibrated task, it is the central point of body temperature, also be that human body is when fever, the place that body temperature rises the earliest, because the tympanum in the ear and arround tissue blood flow communicate with near the hypothalamus blood flow, so the temperature classes of the temperature behind the tympanum and body temperature central point is seemingly, equals to reflect the earliest in the body position of having a fever, therefore, adopt the ear thermometer take temperature can obtain more accurate body temperature value.
With reference to Fig. 1, ear thermometer on the market is when work at present, each ear temperature measurement all needs 3～10 seconds blanking time, promptly after each ear temperature measurement, for guaranteeing next measurement accuracy, ear thermometer all needs 3～10 seconds the measured temperature of time zero clearing, gets back to original state, and measures ambient temperature again, measure treating next time; For some specific occasions, for example in the more place of people, when the crowd is carried out the ear temperature measurement, need to adopt ear thermometer to carry out repeatedly successive measurement, and all need 3～10 seconds waiting time after each the measurement, accumulating to influence measurement efficient.
Summary of the invention
The object of the present invention is to provide a kind of continuous measurement fast, do not need quick measurement ear thermometer and the measuring method thereof waited at interval after each the measurement.
The technological means that the present invention is adopted for its technical problem of solution is:
A kind of quick measurement ear thermometer, comprise infrared ear temperature detecting unit, control unit, display unit and signal conversion unit, described control unit and display unit connect microprocessor respectively, described infrared ear temperature detecting unit connects microprocessor by signal conversion unit, described microprocessor also is connected with the ambient temperature detecting unit, described ambient temperature detecting unit regularly detects ambient temperature, and the ambient temperature information storage got off, through microprocessor processes, the ear temperature temperature that is detected with compensation infrared ear temperature detecting unit is subjected to the influence of ambient temperature.
A kind of ear temperature measurement method of quick measurement ear thermometer after measuring the ear startup temperature fast, comprises following job step:
The invention has the beneficial effects as follows: this product is provided with independent ambient temperature measurement unit, separately ambient temperature is measured, be subjected to the influence of ambient temperature with the measured ear temperature temperature in compensation infrared ear temperature measurement unit, when adopting this product to carry out the ear temperature measurement, need before each ear temperature measurement, not remeasure ambient temperature separately one time, therefore can direct, successive the ear temperature be measured, shortened the waiting time of each measurement clearance greatly, can effectively improve ear temperature measurement efficient, more help using.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the present workflow diagram of product on the market;
Fig. 2 is a theory diagram of the present invention;
