Summary of the invention

Technical problem to be solved in the utility model be to provide one shorten reagent paper response time difference cause measure Result occurs that the color sensor that uses of the probability of error is acquired the device of detection to reagent paper.

This utility model be the technical scheme is that a kind of dress using color sensor that reagent paper is acquired detection Put, including: it is provided with the test strips of several indicator paper blocks, the acquisition component for gathering indicator paper block reflection intensity data is installed Circuit board, each acquisition component is all by a color sensor and to lay respectively at two of described color sensor both sides LED is constituted, adjacent two indicator paper blocks in the corresponding described test strips of each acquisition component, described test strips and circuit board Between each LED of being additionally provided with on locating circuit board and color sensor and prevent the light-illuminating of LED On color sensor every tabula rasa.

Described be respectively formed with on tabula rasa corresponding with each LED on described circuit board for embedding State the through hole of LED, and corresponding with each color sensor on described circuit board be used for embedding described color and pass The through draw-in groove of sensor, the number of described through hole and through draw-in groove and the LED on described circuit board and color sensor Number correspondence identical.

The periphery phase of the described periphery of the through draw-in groove of corresponding each acquisition component on tabula rasa and adjacent through hole It is 0.5～5mm every nearest distance.

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 length or the minimum dimension of alleviating distention in middle-JIAO of test strips；θ is The lighting angle of LED.

A kind of device using color sensor that reagent paper is acquired detection of the present utility model, each reagent block is believed Breath is all by independent LED and color sensor one to one, shortens indicator paper block response time difference and causes measurement result The possibility of error occurs.This utility model reduces the volume of medical science sample, solves miniaturization difficult, a difficult problem for poor user experience. This utility model not only reduces cost, it is also possible to freely regulate the distance between LED and indicator paper block.

Detailed description of the invention

It is acquired examining to reagent paper to a kind of employing color sensor of the present utility model below in conjunction with embodiment and accompanying drawing The device surveyed is described in detail.

As shown in Figure 1, Figure 2, Figure 3 shows, of the present utility model a kind of use color sensor reagent paper is acquired detection Device, including: it is provided with the test strips 2 of several indicator paper blocks 1, is provided with for gathering adopting of indicator paper block 1 reflection intensity data The circuit board 4 of collection assembly 3, each acquisition component 3 is all by a color sensor 33 and to lay respectively at described color sensing Two LED 31 of device 33 both sides and LED 32 are constituted, adjacent two in the corresponding described test strips 2 of each acquisition component 3 Indicator paper block 1, each LED 31 He being additionally provided with on locating circuit board 4 between described test strips 2 and circuit board 4 LED 32 and color sensor 33 and prevent the light-illuminating of LED 31 and LED 32 to color sensor 33 every light Plate 5.Form each two indicator paper block and corresponding two LED of color sensor.

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 test strips；T is length or the minimum dimension of alleviating distention in middle-JIAO of test strips；θ is The lighting angle of LED.

As shown in Figure 4, described be respectively formed with on tabula rasa 5 with each LED 31 on described circuit board 4 and The through hole 51 for embedding described LED 31 and LED 32 that LED 32 is corresponding, and each with on described circuit board 4 Individual color sensor 33 corresponding for embedding the through draw-in groove 52 of described color sensor 33, described through hole 51 and through The number of draw-in groove 52 is corresponding identical with the number of the LED 31 on described circuit board 4 and LED 32 and color sensor 33.
