Description
Technical field
The present invention relates to a kind of biosensing device of medical instruments field, the optical signal transmission detection head on especially this biosensing device.
Background technology
When current photoelectricity biological sensing probes is combined with reagent test sheet and detects, color sensor normally covers red, green, basket optical filter through revising on independently photodiode, then output signal is processed accordingly, color signal could be identified; What have gathers both, but the simulating signal exported, need an A/D circuit to sample, to the further quantification treatment of this signal, just can identify, add the complicacy of circuit, and there is larger conversion and identification error, have impact on the effect of identification.On signal optical source, conventional light source uses thermal light source, and damping capacity is large, poor stability, will to light source calibration, to user bring great inconvenience before needing each use in actual use procedure.The inconvenience caused for above-mentioned reasons and latent instability hidden danger, therefore, be necessary to provide a kind of precision high, digitizing, possess excellent sensitivity and atopic, structure is simple, be convenient to produce, the digital photoelectric biological sensing probes be user-friendly to.
Summary of the invention
In view of the problem existing for existing biology sensor, the invention provides a kind of precision high, digitizing, possess excellent sensitivity and atopic, structure is simple, be convenient to produce, the optical signal transmission detection head of the biology sensor be user-friendly to.
Described biology sensor comprises the detection head on biology sensor reagent test sheet, circuit board, circuit board.
Institute of the present invention according to principle be: be provided with fixing color sensor on circuit boards and the LED of device in mechanical session transmitter, when detecting, by adding electroluminescence to LED, light focuses the light into test pieces through session transmission, color distortion is there is in test pieces owing to reacting with chemical substance (or enzyme), when focused light is irradiated on detection lug, different because of the color amount of refraction that produces of difference, optical transport after refraction is to color sensor, color sensor is converted to the frequency values of total digitalization after receiving Different lightwave, according to frequency values variable quantity just distinguishable go out variable concentrations test sample book and test pieces reaction result, by the microprocessor processes frequency variation signal on circuit board, just quantitative or semiquantitative mode the concentration results of test sample book can be calculated after analytic signal.The sample having color to change after the present invention's total digitalization photoelectricity bio-sensing pick-up unit can realize reacting to various chemical reagent, biology enzyme detects fast, has the features such as simple and efficient, measuring accuracy is high, good stability.
The present invention is achieved in that optical signal transmission detection head, comprises sensor, it is characterized in that, described sensor is color sensor; The one or both sides of described sensor are provided with transmission session, and described transmission session is certain angle of inclination relative to test pieces; Described transmission session upper end is provided with LED hole, the built-in LED in described LED hole.
Described LED and transmission session match each other, and quantity can be one or two.
Color sensor on this pick-up unit circuit board is embedded in the color sensor position on detection head, LED is arranged in LED hole, work is powered up to LED and color sensor by Single-chip Controlling, LED light is allowed to focus in test pieces through optical path, refract light in test pieces after testing head optic path to color sensor receive window, color sensor receives light signal after digital quantization, the color variable quantity on detection lug just can be demonstrated by single-chip microcomputer analyzing and processing, on detection lug, color variable quantity changes with test sample book concentration, the concentration value of test sample book can be drawn thus.
Digital photoelectric biological sensing probes is that a kind of color sensor of programmable digital compatibility interface and optical path detection head of utilizing combines the equipment analyzed reagent test sheet color characteristics.Because digital photoelectric biological sensing probes color sensor and test pieces are as detecting element, by the conversion of color of light to frequency, the color sensor of programmable digital compatibility is integrated in configurable silicon photoelectric diode and current frequency converter on a single cmos circuit, on one chip, be also integrated with RGB (RGB) three kinds of light filters simultaneously, it is the RGB color sensor having digital compatibility interface, the signal exported is digital quantity, can Direct driver standard TTL or CMOS logic input, therefore can directly be connected with microprocessor or other logical circuit.Due to output is digital quantity, and can realize the conversion accuracy of each color channel more than 10, thus no longer needs A/D change-over circuit, and make circuit become simpler, precision is high, possesses excellent sensitivity and atopic.Therefore, the combination of color sensor and test pieces can be widely used in various field, the process measurement of such as medical treatment/medicine (clinical-chemical analysis and disposal), biological industry, environment measurement, food security, the stability assessment of chemicals, colorimeter measure application, colour print, the calibration of computer color monitor and paint, textile, cosmetics and printing material and digital imagery etc., and its range of application constantly expands.Particularly, in medical diagnosis and food manufacture field, totally digitilized photoelectricity biological sensing probes is widely used for analyzing the biological sample comprising blood, urine, food additives.
Advantage of the present invention is that volume is little, and what detection head exported is digital information, and control circuit is simple, and LED is cold light source, stable performance, and its miniaturization easily realizes, and measuring-signal Absorbable organic halogens obtains, and easily realizes the combination with various electronic equipment.
Key point of the present invention is the unique design of optical path, controls reflection angle with regard to the size of adjustable focus point and distance.This pick-up unit design angle is controlled by 10 ° ~ 60 ° scope interior focusing roads, thus realizes the different design needs required, meets different using state.
To sum up telling, the present invention has following advantage:
Structure is simple, and die sinking injection mo(u)lding is easy, and Angle ambiguity is simple, is easy to miniaturization;
Focus on, light intensity is large, and refracted signal is strong;
Signal stabilization, total digitalization, possesses excellent sensitivity and atopic, by force anti-interference;
The combination of as easy as rolling off a log realization and various electronic equipment, that there is biology sensor to retrochromism identification and pick-up unit thereof, can be used for shades of colour discriminance analysis device, as various electronic equipments such as photoelectricity blood glucose meter, edible oil analyser, Urine Analyzer, blood analysers.
