Description

Technical Field

[0001] The utility model relates to the technical field of test paper card boxes, in particular to a test paper card box stabilizing device. Background Art

[0002] Colloidal gold immunochromatography analyzer needs to be used in conjunction with colloidal gold test strips. Immunochromatography technology is a rapid diagnostic technology that emerged in the 1990s as the colloidal gold preparation technology stabilized and was combined with immunoassays. Its essence is still the immune reaction of antibodies and antigens, but traditional immunoassay methods such as enzyme-linked immunosorbent assay (ELISA) place the reaction of antibodies and antigens in a 96-well plate, while immunochromatography technology places the immune reaction in a porous nitrocellulose membrane, so it is also called test strip detection. It is a major form of bedside diagnosis. Immunochromatography detection is mainly completed on chromatography test strips, which are generally loaded in chromatography test strip cartridges. With the development of machine vision technology, cameras are currently used to shoot test strip cartridges, and then image recognition software is used to identify and analyze the grayscale value of the reaction color block of the chromatography test strip in the test strip cartridge, and then the test results are obtained based on the grayscale value.

[0003] However, the existing method is to manually place the test paper into the test paper card box. The size structure of test papers from different manufacturers is different. The test paper card box cannot fix and limit test papers of different sizes, resulting in the position of the test paper being unstable and prone to deviation, making it impossible for the image recognition software to correctly find the position of the color block, resulting in blurred photos. Therefore, we propose a test paper card box stabilizing device to solve the above problem. Utility Model Content

The same spring 13 is fixedly connected between the fixed block 9 and the corresponding connecting rod 11. The test paper is inserted into the upper box cover 1 and the lower box cover 2 from the rear side, and the test paper is tested on the two elastic plastic rods 6. The test paper is squeezed, and the two arc-shaped spring pieces 7 are compressed. The round rod 15 drives the rubber ring 16 to move in the round tube 17 and generates negative pressure in the round tube 17. The connecting rod 11 stretches the spring 13. The arc-shaped spring piece 7 generates a continuous reaction force on the test paper. The elastic force of the first spring piece 4 generates a continuous squeezing force on the test paper, so that the test paper is fixed, and the test paper card box can fix and limit test papers of different sizes, so that the position of the test paper is fixed and not prone to deviation, so that the image recognition software can correctly find the position of the color block to avoid blurring in the photo.

[0022] In this embodiment, specifically: the spring 13 is movably sleeved on the outer side of the corresponding positioning rod 10, and the inner side of the arc-shaped spring piece 7 is fixedly connected with the connecting seat 14, and the setting of the positioning rod 10 plays a positioning effect;

[0023] In this embodiment, specifically: a round rod 15 is fixedly connected to the two sides of the corresponding connecting seats 14 that are away from each other, and a round tube 17 is fixedly connected to the inner walls of both sides of the upper box cover 1;

[0024] In this embodiment, specifically: a rubber ring 16 is fixedly sleeved on the outer side of the round rod 15, and the outer side of the rubber ring 16 is slidably connected to the side wall of the round tube 17;

[0025] In this embodiment, specifically: a first limit block 18 is fixedly connected to the bottom inner wall of the lower box cover 2, and two second limit blocks 19 are fixedly connected to the bottom inner wall of the lower box cover 2;

[0026] In this embodiment, specifically: two third limit blocks 20 are fixedly connected to the top inner wall of the upper box cover 1;

[0028] The utility model is in operation: when in use, the test paper is inserted into the upper box cover 1 and the lower box cover 2 from the rear side, the test paper passes through between the two second limit blocks 19, and the two sides of the test paper squeeze the two elastic plastic rods 6. At this time, the elastic force of the elastic plastic rods 6 generates a reaction force on the test paper, and the test paper compresses the two arc-shaped spring pieces 7. The arc-shaped spring pieces 7 drive the corresponding round rods 15 to move through the connecting seat 14, and the round rods 15 drive the corresponding rubber rings 16 to move. The round rods 15 drive the rubber rings 16 to move in the circular tube 17 and generate negative pressure in the circular tube 17. The arc-shaped spring pieces 7 drive the two rectangular blocks 8 to move, and the rectangular blocks 8 rotate with the corresponding connecting blocks 12.

The connecting rod 11 stretches the spring 13 during the movement. At this time, under the action of negative pressure and the elastic force of the spring 13 itself, the arc-shaped spring piece 7 produces a continuous reaction force on the test paper. At the same time, the bottom of the test paper compresses the first spring piece 4. At this time, under the reaction of the first spring piece 4, the elastic force of the first spring piece 4 produces a continuous squeezing force on the test paper, so that the test paper is fixed, thereby forming a test paper card box stabilizing device, which enables the test paper card box to fix and limit test papers of different sizes, so that the position of the test paper is fixed and not prone to deviation, so that the image recognition software can correctly find the position of the color block to avoid blurry photos.
