Technical Field

[0001] The utility model belongs to the technical field of reagent detection equipment, and more specifically, relates to a reagent card identification device. Background Art

[0002] A handheld reagent card analyzer is a portable, low-cost, compact card reader ideal for rapid qualitative and quantitative analysis of test cards in medical departments. Existing handheld reagent card analyzers require inserting a reagent card into a slot on the housing. A camera then scans the QR code on the card to capture the card's data. To enhance the interior brightness, a light is installed inside the housing. However, this light creates a bright spot on the QR code, making it difficult to read. Utility Model Content

[0003] The purpose of the utility model is to provide a reagent card identification device, aiming to solve the problem that the lighting lamp of the existing reagent card identification device is too bright, resulting in the inability to identify the QR code on the reagent card.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a reagent card identification device, including: a shell, a lampshade, a camera and a lighting lamp; a card slot is provided on the side wall of the shell, the lampshade is fixedly installed in the shell and faces the card slot, the camera and the lighting lamp are both installed on the side of the lampshade away from the card slot, and a camera hole corresponding to the camera is provided on the lampshade.

[0005] In a possible implementation, a light blocking plate is provided on a side of the lampshade facing the slot.

[0006] In a possible implementation, the light baffle and the lampshade are integrally formed.

[0007] In a possible implementation, the camera includes a base and a camera body; the base is detachably connected to the lampshade, and the camera body and the lighting lamp are both fixedly mounted on the base.

[0008] In a possible implementation, a seal is installed between the camera body and the camera hole.

[0009] In a possible implementation, there are multiple lighting lamps, which are evenly arranged along the outer circumference of the camera body.

[0010] In a possible implementation, the lampshade is a plastic lampshade or an acrylic lampshade.

[0011] In a possible implementation, the lampshade is connected to the housing via screws.

[0012] In a possible implementation, the lampshade is provided with an oblong hole for installing the screw.

[0013] In a possible implementation, a slot for the wiring harness to pass through is formed on a side surface of the lampshade.

[0014] Compared with the prior art, the solution shown in the embodiment of the present application is a reagent card identification device of the utility model, in which a lampshade is installed in the shell, and the camera and the lighting lamp are both installed on the side of the lampshade away from the card slot. The camera scans the reagent card in the card slot through the camera hole, and the light emitted by the lighting lamp becomes softer after passing through the lampshade, thereby avoiding the generation of bright spots on the QR code of the reagent card and ensuring that the camera can accurately identify the QR code on the reagent card.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Please also refer to Figure 1 、 Figure 3 and Figure 5 The present invention now provides a reagent card identification device. The device comprises a housing 1, a lampshade 2, a camera 3, and a lighting lamp 4. A card slot 101 is defined on a sidewall of the housing 1. The lampshade 2 is fixedly mounted within the housing 1 and faces the card slot 101. The camera 3 and lighting lamp 4 are both mounted on a side of the lampshade 2 facing away from the card slot 101. The lampshade 2 has a camera hole 201 corresponding to the camera 3.

[0024] Compared with the prior art, the present embodiment provides a reagent card identification device in which a lampshade 2 is installed in a housing 1, and a camera 3 and an illuminating lamp 4 are both installed on the side of the lampshade 2 facing away from the card slot 101. The camera 3 scans the reagent card in the card slot 101 through the camera hole 201, and the light emitted by the illuminating lamp 4 becomes softer after passing through the lampshade 2, thereby avoiding the generation of highlights on the QR code of the reagent card and ensuring that the camera 3 can accurately identify the QR code on the reagent card.

[0025] In some embodiments, see Figures 1 to 3 A light shield 202 is provided on the side of the lampshade 2 facing the card slot 101. In this embodiment, the outer contour of the lampshade 2 is circular. The light shield 202 is arranged around the outer circumference of the lampshade 2. The light shield 202 can effectively focus the light softened by the lampshade 2, so that a large portion of the light is emitted in the direction of the reagent card.

[0026] In some embodiments, see Figure 2 , the light shield 202 is integrally formed with the lampshade 2. In this embodiment, the lampshade 2 and the light shield 202 are integrally formed by injection molding. The integrally formed structure has higher strength and is more solid and durable.

[0027] In some embodiments, see Figure 5 The camera 3 includes a base 301 and a camera body 302. The base 301 is detachably connected to the lampshade 2, and the camera body 302 and the illuminating lamp 4 are both fixedly mounted on the base 301. In this embodiment, the base 301 is detachably connected to the lampshade 2 via fasteners. The camera body 302 and the illuminating lamp 4 are both fixed to the base 301. Since the illuminating lamp 4 is integral with the camera 3, it is easy to assemble it to the lampshade 2.

[0028] In some embodiments, see Figure 3 A seal 303 is installed between the camera body 302 and the camera hole 201. In this embodiment, one end of the camera body 302 passes through the camera hole 201. The seal 303 is a rubber ring. The seal 303 is used to improve the sealing between the camera body 302 and the lampshade 2, preventing strong light from passing through the camera hole 201.

[0029] In some embodiments, see Figure 5 The number of the illuminating lamps 4 is multiple and evenly arranged along the outer circumference of the camera body 302. In this embodiment, the illuminating lamps 4 are LED lamp beads. The multiple illuminating lamps 4 are evenly distributed around the outer circumference of the camera body 302, thereby ensuring that the light emitted by the illuminating lamps 4 is more evenly distributed.

[0030] In some embodiments, the lampshade 2 is made of plastic or acrylic. In this embodiment, the plastic lampshade 2 offers advantages such as high light transmittance, high diffusion, aging resistance, flame retardancy, UV resistance, flexible processing, and pure color. The acrylic lampshade 2 has excellent optical properties, good transparency, and excellent weather resistance, maintaining its optical and mechanical properties even after long-term exposure to outdoor environments.

[0031] In some embodiments, see Figure 1 , the lampshade 2 is connected to the housing 1 by screws 203. In this embodiment, both sides of the lampshade 2 are fixedly connected to the housing 1 by screws 203, which makes it convenient to disassemble and assemble the lampshade 2.

[0032] In some embodiments, see Figure 2 and Figure 3 The lampshade 2 is provided with an oblong hole 204 for mounting a screw 203 . In this embodiment, the position of the lampshade 2 on the housing 1 can be adjusted along the length direction of the oblong hole 204 .

[0033] In some embodiments, see Figure 2 , the side of the lampshade 2 is provided with a slot 205 for the wiring harness to pass through. In this embodiment, the slot 205 is opened on the side of the lampshade 2, and the wires connected to the camera body 302 and the illuminator 4 pass through the slot 205 and are connected to the power supply.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
