Description

Technical Field

[0001] The utility model belongs to the technical field of allergen detection cards, and specifically relates to an allergen-specific IgE detection plate. Background Art

[0002] Allergen-specific IgE generally refers to an allergen-specific IgE antibody present in human serum, which can mediate the occurrence of allergic reactions. Detecting allergen-specific IgE can help determine whether a patient has an allergic reaction to certain allergens. In case of abnormal allergen-specific IgE, contact with related allergenic substances should be avoided.

[0003] For general allergen blood tests, serum and red blood cells need to be separated first, and then serum and allergen sample reagents are added to detect the final result. However, existing detection structures do not separate serum from red blood cells and directly perform reactions with allergen reagents. Although this reduces operating costs, it affects the accuracy of the final detection. In addition, there is no protective structure on the detection card, resulting in inaccurate detection results when foreign objects accidentally fall into the sample addition hole. Content of the Utility Model

[0004] The purpose of the utility model is to provide an allergen-specific IgE detection plate to solve the technical problem that existing detection structures do not separate serum from red blood cells and directly perform reactions with allergen reagents, thus affecting the accuracy of the final detection.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An allergen-specific IgE detection plate, comprising:

[0007] A bottom plate, on which a cover plate is hingedly installed, and the bottom plate is respectively connected with equidistantly corresponding large notches and small notches, and the large notches and small notches are connected by an inclined notch with an opening downward;

[0008] A sealing film, on the outer wall edge of the large notch near the inclined notch, a sealing film is adhesively fixed, and a lifting ear adapted to it is connected to the sealing film;

[0009] A protection component, the protection component includes a block integrally formed on the cover plate, and the block is connected with a bayonet on the bottom plate in a limiting manner.

[0010] Further, the protection component further includes a rotating ring movably connected to the bottom plate, one end of the rotating ring is connected to a reciprocating lead screw extending into the bottom plate through a movable shaft, and both ends of the reciprocating lead screw are helically driven with blocks symmetrically centered on the block.

[0011] Further, one end of the stopper extends to the bayonet, and a strip groove is connected along the width direction of the bottom plate. As the rotating ring rotates, the stopper and the block on the cover plate are clamped or separated from each other.

[0012] Further, a rotating cavity is provided on the outer wall of the reciprocating lead screw and is placed inside the bottom plate.

[0013] Further, a socket for inserting and connecting with an external sampling straw is opened on the bottom plate.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] (1) A sealing film connected by a large notch is provided. Through natural precipitation, serum and red blood cells will naturally separate. For the coagulated serum, the sealing film is torn off by lifting the ear. In this way, due to the action of gravity, the serum slides into the small notch through the inclined opening, thereby obtaining the serum, avoiding the influence of red blood cells on the detection of allergen characteristics, and improving the accuracy of detection data.

[0016] (2) A protection component is provided. When the detection board is not in use, the block on the cover plate is connected to the bayonet on the bottom plate in a limiting manner, and then the rotating ring is pushed to rotate to make the reciprocating lead screw move. With the help of the action of screw drive, the stopper further clamps and limits both ends of the block, ensuring the stability of the connection of the connecting piece, and thus improving the safety of the structure when not in use.
