In above fetch equipment, because these elements that obtain figure are all in the box in a sealing, in image in obtaining test-strips or proving installation, usually all need first to have a light source to be radiated in testing element and/or proving installation, and then obtain image and image is analyzed.This is just necessary to providing the system of illumination that a kind of improvement is provided, and reduces the impact of light-source system on image.
Summary of the invention
On the one hand, the utility model provides a kind of illuminator being included in immune fetch equipment, this illuminator comprises: a box, in the bottom of box, comprise the supporting plate of depositing test-strips or containing test strip, it is characterized in that, at the top of box, above the supporting plate in the face of described, the plastic septum that comprises a light-permeable arranges one or more LED lamps near the back side of dividing plate.
In some preferred modes, this plastic septum is PE material.Preferred, dividing plate journey groove shape arranges one or more LED lamps in groove.
In some preferred modes, LED lamp is fixed and is placed in a cover plate is upper, and wherein, LED lamp is between cover plate and the back side of plastic septum.In other preferred modes, described cover plate and plastic septum chain connection.In other preferred modes, LED lamp equably branch at the back side of plastic septum.Like this, the some light that these lamps send entered after the refraction of plastic septum, became uniform irradiation in test-strips, and the image obtaining by optical element is like this even, there will not be the part that light and shade is different.
In a preferred mode, described supporting plate is movable supporting plate, and this supporting plate is the bottom back and forth movement of box again.
In other preferred modes, immune fetch equipment comprises the element that obtains testing element image, and wherein said element is CCD or COMS photograph component.
In some preferred modes, test-strips is immunochromatography reagent bar.Preferably, immunochromatography reagent bar comprises surveyed area, fixing one deck antibody on surveyed area.
In some preferred modes, the section of box is right-angled trapezium, and dividing plate is trapezoidal minor face, and supporting plate is trapezoidal long base.In some preferred modes, box also comprises the mirror of inclination, and the angle of the supporting plate of the mirror of inclination is 45 degree, and dividing plate is parallel with supporting plate, and the length of dividing plate is less than the length that is exposed to the supporting plate in cavity simultaneously.
beneficial effect
The point light that these LED lamps send, after the refraction of plastic septum, becomes uniform irradiation in test-strips, and the image obtaining by optical element is like this even, there will not be the part that light and shade is different.Avoid the light of LED lamp direct projection to enter minute surface and disturbed test result simultaneously.
