Problems solved by technology
These devices use LED light sources to illuminate the detection area of the test paper, obtain the reflected light intensity through the photosensitive device, and judge the color of the detection area by the microprocessor. Therefore, it is necessary to avoid the interference of ambient light. Light treatment, such as adding light shielding agent, will have some restrictions on the color of the shell, making the color of the shell monotonous, affecting the market competitiveness of the product

Embodiment Construction
[0014] The present invention will be further described below in conjunction with embodiment:
[0015] Such as Figure 1 ~ Figure 3 As shown, a colloidal gold test pen light-proof bracket includes a base 3 and a cover plate 1. The base 3 is provided with a test paper cavity 2 for accommodating the color development area of the test paper. The cover plate 1 is detachably fixed on the base 3, the cover plate 1 is arranged above the test paper cavity 2, and the base 3 and the cover plate 1 are made of black light-proof material.
[0016] Described base 3 comprises base plate 6 and two side plates 4, and two described side plates 4 are parallel to each other and are fixedly arranged on base plate 6, and the area enclosed by described base plate 6 and side plate 4 is test paper cavity 2, so Two baffles 7 are fixed under the cover 1 , the two baffles 7 are parallel to each other, and the inner surfaces of the two baffles 7 are attached to the outer surfaces of the two side panels ...

Abstract
The invention relates to a light-shielding bracket for a colloidal gold test pen. The bracket comprises a base and a cover plate. A test paper cavity for accommodating a test paper developing region is formed in the base, the cover plate is detachably and fixedly arranged on the base, the cover plate is arranged above the test paper cavity, and the base and the cover plate are made from a black light-shielding material; the base comprises a bottom plate and two side plates, wherein the two side plates are parallel to each other and are fixed on the bottom plate, a region formed by encircling of the bottom plate and the side plates is the test paper cavity, two baffle plates are fixedly arranged under the cover plate, the two baffle plates are parallel to each other, and the inner side faces of the two baffle plates are attached to the outer side faces of the two side plates separately. The developing region of the detection test paper is shielded, so that the influence of environmental light on a testing process is eliminated, and the light-shielding effect is good; the light-shielding function is no longer accomplished by a housing of the test pen, and a light-shielding agent needs not to be added into the housing, so that the color and luster of the housing are prevented from being limited by adding the light-shielding agent, and a harmful effect of a single color on the product competitiveness is eliminated; and the bracket is simple to assemble and firm to connect.
Description
technical field [0001] The invention belongs to a detection device for colloidal gold test paper, and relates to a test pen for early pregnancy and ovulation detection, in particular to a light-proof support for the colloidal gold test pen. Background technique [0002] Colloidal gold, also known as gold sol, refers to a gold sol with a diameter of dispersed phase particles between 1-150nm, which belongs to a heterogeneous heterogeneous system. Colloidal gold can be used as a marker for immunohistochemistry. Labeling has developed into an important immunolabeling technique. Early pregnancy detection is an important application of colloidal gold labeling technology. At present, the in vitro diagnostic test strips used for early pregnancy detection on the market usually use the naked eye to judge the color development result after loading the test sample, and then draw a diagnostic conclusion. The digital test pen or test stick uses a light detection device to test the test a...
