Summary of the invention

The technical problem to be solved is to provide and a kind of can gather the detected multiple conversion zone of medical science sample simultaneously The device that test paper is detected by the employing color sensor of color value one to one.

The technical solution adopted in the present invention is: a kind of device using color sensor to detect test paper one to one, including: It is provided with the test strips of several indicator paper blocks, the circuit board of the acquisition component of reflection intensity data for gathering indicator paper block is installed, The number of described acquisition component is identical with the number of described indicator paper block, and one_to_one corresponding arrange, each acquisition component be all by One LED and a color sensor are constituted, and are additionally provided with for locating circuit board between described test strips and circuit board Each LED and color sensor and prevent the light-illuminating of LED to color sensor every tabula rasa.

Described be respectively formed with on tabula rasa corresponding with each LED on described circuit board described for embedding The through hole of LED and corresponding with each color sensor on described circuit board for embedding described color sensor Draw-in groove, described through hole and the number of draw-in groove are identical with the number of the acquisition component on described circuit board.

The described periphery of through hole of corresponding same group of acquisition component and the base of draw-in groove on tabula rasa are separated by nearest distance and are 0.5～5mm.

Ultimate range between described acquisition component and corresponding indicator paper block is:

$X=\frac{T/2}{\tan \mathrm{\θ}/2}$

Wherein, X is the distance between LED and test strips；T is the minimum dimension in the length of test strips or width； θ is the lighting angle of LED.

A kind of device using color sensor that test paper is detected one to one of the present invention, it is possible to simultaneously gather detected medical science The color value of the multiple conversion zone of sample, and reduce the volume of medical science sample so that its structure becomes simple, obtains exactly Take the inspection result of urine examination.In the present invention, each reagent block message is by independent LED and color sensor one to one, Shortening test paper reaction time difference causes measurement result the possibility of error occur.In order to eliminate white led lamps and color sensor Between otherness, adjust LED light intensity in scope of design, after having adjusted light intensity, reusable sensor read RGB data, Store whole LED light intensity value and adjust after sensor rgb value, then during official testing use.Urine sample color may be to inspection Survey result and produce impact, therefore add the correcting process of each reagent block.The present invention reduces the volume of medical science sample simultaneously, Solve miniaturization difficulty, a difficult problem for poor user experience.

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, test paper detected by the employing color sensor of the present invention one to one device and detection side Method is described in detail.

As it is shown in figure 1, a kind of of the present invention uses color sensor that test paper detects device one to one, including: it is provided with The test strips 2 of several indicator paper blocks 1, is provided with the circuit board 4 of acquisition component 3 for gathering indicator paper block 1 reflection intensity data, The number of described acquisition component 3 is identical with the number of described indicator paper block 1, and one_to_one corresponding is arranged, each acquisition component 3 It is all to be made up of a LED 31 and a color sensor 32, is additionally provided with between described test strips 2 and circuit board 4 Each LED 31 on locating circuit board 4 and color sensor 32 and prevent the light-illuminating face of LED 31 Colour sensor 32 every tabula rasa 5.

As shown in Figure 2 and Figure 3, described it is respectively formed with on tabula rasa 5 and each LED on described circuit board 4 31 corresponding through holes 51 for embedding described LED 31 and with each color sensor on described circuit board 4 The 32 corresponding draw-in grooves 52 for embedding described color sensor 32, the number of described through hole 51 and draw-in groove 52 is with described Circuit board 4 on the number of acquisition component 3 identical.

The described LED 31 distance away from described color sensor 32 is enough near, makes the color sensor 32 will not again Receive the light of LED 31.Therefore, the described periphery of the through hole 51 of corresponding same group of acquisition component 3 on tabula rasa 5 with It is 0.5～5mm that the base of draw-in groove 52 is separated by nearest distance, i.e. each LED 31 and adjacent color sensor 32 it Between thickness to be passed through be 0.5～5mm separate every tabula rasa.

Ultimate range between described acquisition component 3 and corresponding indicator paper block 1 is:

$X=\frac{T/2}{\tan \mathrm{\θ}/2}$

Wherein, X is the distance between LED and indicator paper block 1；T is the minimum dimension in the length of test paper or width；θ is LED Lighting angle.So that the light that LED 31 is got impinges upon on indicator paper block 1 completely.According to LED 31 rising angle With the big I of indicator paper block 1 calculates the ultimate range between indicator paper block 1 and LED 31 and color sensor 32.

If LED 31 lighting angle is 30 degree, indicator paper block 1 size is 4*4mm, its LED 31 and color sensor Distance between 32 and indicator paper block 1 is calculated as 7.5mm by above-mentioned formula.
