Description
Technical field
This utility model relates to medical apparatus and instruments, relates in particular to a kind of infrared radiation thermometer.
Background technology
Infrared temperature-test technology is widely used in industrial circle with its untouchable characteristics, begins to be widely used in the human body thermometric in recent years.Existing infrared radiation thermometer is various in style, and function is similar, and the structure composition all adopts optical system, photodetector, signal amplifier and signal processing, demonstration output etc. partly to form.
The difference of normal human's temperature and improper human body temperature only has the several years, and being used for the thermometric infrared radiation thermometer of human body has certain requirement to precision, and the common infrared radiation thermometer that is used for commercial measurement can't meet the demands.Produced thus and be specifically designed to the degree of precision infrared radiation thermometer of measuring body temperature.
Because distance has direct influence to test result, require the operator need guarantee to test out patient's body temperature accurately, otherwise test result data can have artificial deviation in various degree at the optimum distance prescription, cause false clinical data, mislead the clinical diagnosis result.Be used for the thermometric infrared radiation thermometer of human body at present, all require the operator when test, will maintain a certain distance, but do not provide the reference or the means of testing of distance, single laser designator structure that it adopted, can only indicate the position of test for the operator, and can not determine the distance of test.In view of this, how for the operator provides one accurately apart from basis of reference, reducing the instructions for use to the operator, overcome the false measurement result that causes because of range deviation, is that problem to be solved is arranged.
Summary of the invention
Can not provide accurately apart from basis of reference in order to solve existing infrared radiation thermometer, false measurement result, the operator that existence causes because of range deviation uses inadequately not enough easily, this utility model provide a kind of can provide accurately apart from basis of reference, measurement result more accurately, the operator uses more convenient medical grade infrared radiation thermometer.
This utility model adopts following technical scheme:
The medical grade infrared radiation thermometer, comprise the Optical devices, photodetector, signal amplifier, the signal processor that are linked in sequence, an outfan of described signal processor connects display, and two outfans in addition of described signal processor connect first laser generator and second laser generator that the emission light beam becomes to converge angle.
Further, described first laser generator becomes angle to place with second laser generator.
Technical conceive of the present utility model is: the outfan at signal processor connects two laser generators that the emission light beam becomes to converge angle, and the meet of its emission light beam has promptly been indicated best measuring distance.Like this, the operator is as long as hand-held this infrared radiation thermometer moves, and when two emission light beams project hot spot on the human body and overlap, promptly indicated this to install desired optimum detection distance, and simultaneously, this hot spot has also been indicated the position of test.Like this, owing to provide accurately apart from basis of reference, the operator uses more convenient.
Operation principle is as follows: Optical devices focus on the radiating infrared ray in tested position on the receive window of detecting element photodetector, and the infrared ray that enters instrument is limited in the fixed range; Photodetector is converted to the signal of telecommunication with the infrared signal that receives, input signal amplifier; Signal amplifier amplifies the signal of telecommunication of input, obtain the signal of telecommunication that signal processor can discern, handle after, input signal processor carries out analysis, the processing of signal; Signal processor is analyzed, is handled the signal of telecommunication of input, obtains final temperature data, send display to show; Simultaneously, signal processor controls first laser generator and second laser generator promptly sends the optimum distance guidance light before test, and pilot operationp person is controlled at optimum state and test position with measuring distance.
The beneficial effects of the utility model are: can provide accurately apart from basis of reference, temperature-measuring results more accurately, the operator uses more convenient.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Fig. 2 is the fundamental diagram of first laser generator and second laser generator.
The specific embodiment
With reference to Fig. 1-2: the medical grade infrared radiation thermometer, comprise the Optical devices, photodetector, signal amplifier, the signal processor that are linked in sequence, an outfan of described signal processor connects display, and two outfans in addition of described signal processor connect first laser generator 1 and second laser generator 2 that the emission light beam becomes to converge angle.
2 one-tenth angles of first laser generator 1 described in the present embodiment and second laser generator are placed, and launch light beams to produce into two of converging angle.
Present embodiment becomes to converge two laser generators of angle at the outfan connection emission light beam of signal processor, and meet of its emission light beam has promptly been indicated best measuring distance.Like this, the operator is as long as hand-held this infrared radiation thermometer moves, and when two emission light beams project hot spot on the measured body surface 3 and overlap, promptly indicated this to install desired optimum detection distance, and simultaneously, this hot spot has also been indicated the position of test.Like this, owing to provide accurately apart from basis of reference, the operator uses more convenient.
The operation principle of this device is as follows: Optical devices focus on the radiating infrared ray in tested position on the receive window of detecting element photodetector, and the infrared ray that enters instrument is limited in the fixed range; Photodetector is converted to the signal of telecommunication with the infrared signal that receives, input signal amplifier; Signal amplifier amplifies the signal of telecommunication of input, obtain the signal of telecommunication that signal processor can discern, handle after, input signal processor carries out analysis, the processing of signal; Signal processor is analyzed, is handled the signal of telecommunication of input, obtains final temperature data, send display to show; Simultaneously, signal processor controls first laser generator 1 and second laser generator 2 promptly sends the optimum distance guidance light before test, and pilot operationp person is controlled at optimum state and test position with measuring distance.
The measurement result of infrared radiation thermometer is subjected to many factor affecting, and main is measurand radiance uncertainty, is not easy to measure the measurand actual temperature; Be used for the thermometric infrared radiation thermometer of human body at present, all be set to 0.95 with radiance is fixed, and the human body radiation rate is because individual variation, its radiance is substantially between 0.93～0.96, thus, the fixing practice of radiance is in the deviation that has fundamentally caused measurement result.In order to overcome the influence of radiance difference that individual variation causes to measurement result, present embodiment has adopted many radiances meansigma methods algorithm, promptly earlier result of detection is composed with the radiance in the human infrared radiation scope, draw a plurality of results, again a plurality of result's values of averaging are handled, finally provide measurement result, this result's accuracy is better than existing human body infrared radiation thermometer.
