DETAILED DESCRIPTION
[0028] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.
[0029] It should be noted that the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above drawings are intended to cover non-exclusive inclusion, for example, a process, method, device, product or equipment containing a series of steps or units does not have to be limited to the clearly listed steps or units, but can include other steps or units that are not clearly listed or inherent to the process, method, product or equipment.
[0030] The following will be described in detail in combination with the drawings Figures 1-4 The present application will be further described in detail.
[0031] Reference Figures 1-3 As shown in the figure, the four-in-one detection kit comprises a box body 1, four detection modules are arranged side by side on the box body 1, the detection module comprises a sample hole 2 opened at the top of the box body 1, a flow guide assembly arranged at the bottom of the sample hole 2, an observation window 3 arranged at the top of the box body 1, and a reagent strip fixing assembly arranged in the inner cavity of the box body 1;
[0032] The flow guide assembly comprises a first flow guide ring 4 and a second flow guide ring 5, the second flow guide ring 5 is sleeved on the side of the first flow guide ring 4, the top end opening of the second flow guide ring 5 is consistent in size with the bottom end opening of the sample hole 2, and the annular flow guide channel 6 is formed between the first flow guide ring 4 and the second flow guide ring 5;
[0033] The reagent strip fixing assembly is used for fixing the reagent strip directly below the sample hole 2 and the observation window 3.
[0034] Based on the above structure, during use, the reagent strip is fixed in the box 1 by the reagent strip fixing assembly, and then the sample solution is dripped into the first guide ring 4 from the sample dispensing hole 2. When the sample solution overflows from the first guide ring 4, it will enter the guide channel 6 between the first guide ring 4 and the second guide ring 5. Since the bottom outlet of the guide channel 6 is also located directly above the reagent strip, the sample solution that enters the guide channel 6 is finally absorbed by the reagent strip at the bottom, reducing the occurrence of sample solution overflow.
[0035] like Figure 3 As shown, both the first guide ring 4 and the second guide ring 5 are conical, and the larger opening ends of the first guide ring 4 and the second guide ring 5 face upwards to maximize the size of the sample solution inlet, making it easier to drip the sample solution in. The smaller opening ends of the first guide ring 4 and the second guide ring 5 face downwards to reduce the size of the sample solution outlet, ensuring that the sample solution flows to the reagent strip. Furthermore, the bottom of the first guide ring 4 is higher than the bottom of the second guide ring 5 to facilitate the flow of the sample solution below the first guide ring 4.
[0036] Further optimizations include, for example Figure 3 As shown, a plurality of connecting ribs 7 are provided between the first guide ring 4 and the second guide ring 5 to fix the first guide ring 4. In this embodiment, the first guide ring 4 and the second guide ring 5 are coaxially arranged.
[0037] like Figure 4 As shown, to facilitate the fixing of the test strips, the test strip fixing assembly includes two U-shaped clamping plates 8 (the U-shaped clamping plates 8 of the four detection modules are arranged side by side) which are arranged opposite each other at the bottom of the inner cavity of the box 1. The bottom end of the second flow guide ring 5 is suspended directly above one of the U-shaped clamping plates 8. When installing the test strip, the two ends of the test strip are placed in the U-shaped clamping plates 8 respectively to complete the positioning of the test strip. Since the four-in-one detection requires multiple different test strips, in order to avoid the test strips being placed in the wrong position, the test strip fixing assembly also includes a limiting block 13 set in one of the U-shaped clamping plates 8. The limiting block 13 of each test strip fixing assembly is located at a different position of the corresponding U-shaped clamping plate 8. In this way, notches can be set at different positions on different test strips, and the test strips can be installed to fit the corresponding limiting block 13, ensuring that the test strips are installed accurately.
[0038] Further optimizations include, for example Figure 2 As shown, in order to avoid unevenness inside the reagent strip box 1, several pressure plates 9 are set inside the box. The pressure plates 9 are respectively set on the side of the observation window 3 near the flow guiding component and the side away from the flow guiding component. The pressure plates 9 press down on the reagent strip from top to bottom to ensure that the reagent strip is flat. The bottom of the pressure plate 9 is U-shaped and will not interfere with the normal use of the reagent strip.
[0039] Further optimizations include, for example Figure 2 andFigure 4 As shown, the box body 1 specifically comprises a lower bottom plate and an upper shell arranged on the lower bottom plate, the flow guide assembly is arranged on the upper shell, and the reagent strip fixing assembly is arranged on the lower bottom plate; in order to facilitate assembly of the box body 1, a plurality of positioning sleeves 10 are arranged on the lower bottom plate, and a plurality of positioning rods 11 corresponding to the positioning sleeves 10 are arranged on the upper shell; in this way, during installation, the positioning rods 11 are aligned with the positioning sleeves 10, the alignment of the lower bottom plate and the upper shell can be completed, and after the positioning rods 11 are completely inserted into the positioning sleeves 10, the upper shell is fixed on the lower bottom plate.
[0040] As shown in the drawings, Figure 1 As shown, the top surface of the box body 1 is provided with an information column 12, which can be used for attaching a convenient sticker with information of a sample liquid and the like.
[0041] In summary, during use, the reagent strip is fixed in the box body 1 by the reagent strip fixing assembly, and then the sample liquid is dropped into the first flow guide ring 4 from the sample adding hole 2, when the sample liquid overflows from the first flow guide ring 4, it will enter the flow guide channel 6 between the first flow guide ring 4 and the second flow guide ring 5, and since the bottom outlet of the flow guide channel 6 is also located directly above the reagent strip, the sample liquid finally enters the flow guide channel 6 and is absorbed by the reagent strip at the bottom, thereby reducing the occurrence of sample liquid overflow.
[0042] The above is only the preferred embodiment of the application, and the utility model is not limited to the above embodiments. It can be understood that other improvements and changes directly derived or thought of by those skilled in the art without departing from the spirit and concept of the utility model should be considered to be included in the protection scope of the utility model.
