Description

TECHNICAL FIELD

[0001] The present application relates to the field of reagent detection kit structure, and particularly relates to a multi-association detection kit. BACKGROUND

[0002] Multi-association detection technology is widely used in medical diagnosis, environmental monitoring, food safety and other fields due to its high efficiency and convenience. Traditional multi-association detection kits usually adopt a fixed test paper array design, that is, multiple test papers are pre-installed on the same carrier, and sample loading and result reading are completed through a single detection port. However, the existing technology has the following key problems:

[0003] Insufficient test paper positioning accuracy: traditional card slots or adhesive fixing methods cannot guarantee the position stability of test papers during transportation or detection. Especially in environments such as vibration, temperature and humidity changes, test papers are prone to micro-displacement (offset of more than 0.3 mm), which causes misalignment between the detection port and the sample loading area of the test paper, affecting detection accuracy.

[0004] Poor modularity and scalability: Most test kits have a one-time integrated design of test papers, which cannot be flexibly replaced or increased or decreased in test paper types according to detection needs, limiting the adaptability of multi-index detection. For example, in infectious disease screening, if new detection items need to be added, the user must replace the entire test kit, causing resource waste.

[0005] Weak anti-interference ability: The existing test paper fixing structure (such as plastic buckles) is prone to fatigue failure after being opened and closed multiple times, causing the test paper to loosen, especially in the POCT (point-of-care testing) scene, the shaking of handheld devices may further exacerbate this problem.

[0006] In view of the above problems, the industry attempts to optimize by improving the test paper carrier material or adding auxiliary positioning structures, but often sacrifices the compactness or cost-effectiveness of the test kit, therefore, there is an urgent need for a multi-association detection kit design scheme with high-precision positioning, modular expansion and simple operation.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0042] Specifically, such as Figures 1-7 As shown in the embodiment of this application, a multi-unit test kit is provided. This test kit is injection molded from high-strength engineering plastic (such as ABS or polycarbonate), and has an overall rectangular structure with dimensions of 200mm × 150mm × 50mm (length × width × height). An internal accommodating cavity 110 is provided, which is a rectangular cavity with dimensions of 180mm × 130mm × 40mm (length × width × height) to accommodate the multi-unit test device 200 and the abutment member 300. A detection port 130 and an observation window 120 are provided at the top of the accommodating cavity 110. Both the detection port 130 and the observation window 120 are connected to the accommodating cavity 110. The detection port 130 is used to load test samples (such as blood, saliva, etc.), and the observation window 120 is covered with a transparent acrylic plate to facilitate the user's reading of the test results after the test strip is applied.

[0043] The detection port 130 has a removable sealing cap on its outer edge, which is connected to the detection box 100 via a snap-fit ​​structure to prevent external contaminants from entering. The acrylic plate edge of the observation window 120 is coated with a waterproof rubber ring to ensure that the interior of the cavity is isolated from the outside. In addition, the bottom of the receiving cavity 110 is provided with a drainage channel to collect any liquid that may overflow during the detection process and discharge it through the drain hole at the bottom to avoid liquid residue affecting the detection accuracy.

[0044] In the embodiment of the present application, the multi-union detection device 200 is arranged in the accommodating cavity 110, and the multi-union detection device 200 comprises a supporting assembly 220 and a plurality of supporting frames 210. The supporting assembly 220 mainly comprises an elastic member 221 and a supporting plate 222. The elastic member 221 is arranged at the bottom of the accommodating cavity 110 and is fixedly connected with the bottom of the accommodating cavity 110. In the embodiment of the present application, the elastic member 221 is provided with two, and preferably, the elastic member 221 can be provided with a plurality according to actual conditions. The supporting plate 222 is supported on one end of the elastic member 221 away from the bottom of the accommodating cavity 110. The supporting plate 222 is arranged at a position corresponding to the observation window 120, so that the elastic member 221 can conveniently support the supporting plate 222 and realize linear motion. The supporting frame 210 provided with a detection test paper 212 is arranged on the supporting plate 222, and the supporting frame 210 is supported by the elastic member 221.

[0045] In the embodiment of the present application, the elastic member 221 is a compression spring.

[0046] In the embodiment of the present application, the supporting frame 210 is a supporting frame 211, and the detection test paper 212 is fixedly arranged in the supporting frame 211, so that the detection test paper 212 is fixed by the supporting frame 211. Each detection test paper 212 has a length of 80 mm and a width of 5 mm, and a detection line (T line) and a quality control line (C line) are arranged on the surface of the detection test paper 212, which are used for multi-index detection.

[0047] The first matching position 213 is arranged on the supporting frame 210, and the first matching position 213 mainly comprises a limiting strip. The second matching position 223 is arranged on the supporting plate 222 at a position corresponding to the first matching position 213. The second matching position 223 is a first limiting groove in the embodiment of the present application. The cross section of the first limiting groove is the same as that of the limiting strip, so that the limiting strip can be well clamped into the first limiting groove, and the supporting plate 222 can conveniently support and limit the detection test paper 212.

[0048] The first matching position 213 on the supporting frame 210 and the second matching position 223 on the supporting plate 222 are arranged in the direction along the long strip shape of the detection box 100.

[0049] In order to realize multi-union detection, a plurality of detection test papers 212 need to be arranged in the accommodating cavity 110 in the embodiment of the present application. Specifically,

[0050] As shown in Figure 7 The third matching position 214 is arranged on one side of the supporting frame 210 relative to the first matching position 213. The third matching position 214 is a second limiting groove. The cross section of the third matching position 214 is the same as that of the limiting strip, so that the limiting strip is clamped into the second limiting groove.

[0051] In the above structure, when the plurality of support frames 210 are assembled, the third matching positions 214 on the adjacent support frames 210 are connected with the first matching positions 213, and the adjacent support frames 210 are assembled together to assemble the plurality of test papers 212 to be placed into the accommodating cavity 110.

[0052] In order to facilitate the plurality of support frames 210 to enter the accommodating cavity 110, in the embodiment of the application, a feeding port 140 is formed at one side of the accommodating cavity 110, the feeding port 140 communicates with the accommodating cavity 110, and the width of the feeding port 140 is equal to the width of the support frame 210, so that the support frame 210 is positionally limited by the feeding port 140, and the first matching position 213 on the support frame 210 is just butted against the second matching position 223 on the support plate 222.

[0053] Since the bottom of the support plate 222 is supported by the elastic member 221 in the embodiment of the application, in order to facilitate the support frame 210 to be placed on the support plate 222, a transition surface 224 is arranged on the support plate 222 at a position facing the feeding port 140, as shown in Figures 3-4 When the test paper 212 enters the accommodating cavity 110 through the feeding port 140, the test paper 212 enters the support plate 222 through the transition surface 224.

[0054] In the embodiment of the application, the transition surface 224 is mainly arranged as an inclined surface, one end of the inclined surface facing the feeding port 140 abuts against the bottom position of the feeding port 140, and the support frame 210 with the test paper 212 is facilitated to enter the support plate 222 along the transition surface 224.

[0055] In the above structure, since the elastic member 221 is arranged, in order to facilitate the transition surface 224 to abut against the feeding port 140, as shown in Figures 1-2 The adjusting member 225 is arranged on the two side positions of the support plate 222, and the adjusting groove 150 corresponding to the adjusting member 225 is formed on the detection box 100, the adjusting member 225 is located in the adjusting groove 150, so that when the adjusting member 225 moves in the adjusting groove 150, the transition surface 224 on the support plate 222 moves up and down at the position of the feeding port 140, when the adjusting member 225 moves to a position in the adjusting groove 150, one end of the transition surface 224 on the support plate 222 abuts against the bottom position of the feeding port 140, and the plurality of support frames 210 with the test papers 212 are facilitated to enter the support plate 222 through the transition surface 224, as shown in Figure 2

[0056] ​When the test strip 212 is located on the support plate 222, the test strip 212 needs to be moved from the position of the observation window 120 to the position of the detection port 130, so that the test strip 212 can be tested at the detection port 130. The specific structure is as follows:

[0057] In this embodiment, the detection box 100 has a sliding groove 160, and an adjustment device 400 is provided in the sliding groove 160. There are two sliding grooves 160, respectively located on both sides of the observation window 120, and the sliding grooves 160 are positioned along the first mating position 213, such that the adjustment device 400 in the sliding groove 160 abuts against the first mating position 213. The adjustment device 400 is mainly configured as a pressing member 410, such as... Figure 2 As shown, when the test paper 212 is located on the support plate 222, the test paper 212 is clamped by the elastic member 221 and the pressing member 410, which facilitates the fixing of the test paper 212.

[0058] In this device, the end of the pressing member 410 facing the test paper 212 abuts against the third mating position 214 on the support frame 210. At the same time, the third mating position 214 corresponds to the slide groove 160 in position, so that the pressing member 410 can push the support frame 210 facing the slide groove 160, making it convenient to move the outermost support frame 210 to the position of the detection port 130 for detection.

[0059] To prevent other support frames 210 from being moved to the detection port 130 position during movement, an abutment 300 is provided in this embodiment, such as... Figure 5 As shown, the abutment 300 is positioned at the corresponding detection port 130. The height of the abutment 300 is equivalent to the height of the support frame 210 that abuts against the pressing member 410. This allows the support frame 210 to move above the abutment 300 when the pressing member 410 moves the support frame 210. The lower support frame 210 is blocked by the side of the abutment 300, facilitating the testing of only one test strip 212. After the test is completed, the pressing member 410 can push the test strip 212 back into the observation window 120 for easy observation of the test results.

[0060] Among the above, the abutting part 300 is provided with a fourth matching position 310 corresponding to the first matching position 213 and the third matching position 214 in the direction towards the support frame 210, when the support frame 210 is above the abutting part, the support frame 210 is abutted by the abutting part 300 at the position of the detection port 130, the support frame 210 is limited by the fourth matching position 310, the structure of the fourth matching position 310 in the application is adapted with the third matching position 214, which facilitates the fourth matching position 310 to limit the support frame 210.

[0061] The above embodiments are only used to illustrate the technical method of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical method of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the present application.
