Description

Technical Field

[0001] This utility model relates to the field of detection card holders for animal disease chromatography, specifically a detection card holder for animal disease chromatography that can be quickly installed on a machine. Background Technology

[0002] A chromatography test card holder is a device used to install test strips, making it easier for staff to inspect the test strips on animal disease test cards; However, current multi-test cards on the market only support visual interpretation and cannot be determined by instruments. Visual interpretation has significant limitations because it relies heavily on the subjective recognition ability of the human eye and is easily affected by various factors such as ambient lighting conditions, individual color vision differences, and the experience level of the operator. This makes it easy to miss or misjudge weak positive results or ambiguous signals such as low concentrations of biomarkers during the testing process. In view of this, there is an urgent need to develop a test card holder device for animal disease chromatography that can be quickly installed on the instrument. This device integrates multiple test cards into a card holder, enabling accurate and rapid multi-testing, effectively improving the accuracy and efficiency of the test. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a rapid instrument-reading device for animal disease chromatography detection cards, in order to solve the technical problems of current multi-part detection cards on the market that rely solely on visual interpretation and cannot be determined by instrument readings. Furthermore, visual interpretation is easily affected by ambient lighting conditions, individual color vision differences, and the experience level of the operator, leading to missed or misjudged results for weak positive results or ambiguous signals such as low-concentration biomarkers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a card holder device for animal disease chromatography that can be quickly loaded into a machine, comprising a card holder device and a test card. The card holder device includes multiple sets of card holders, and a first magnetic surface and a second magnetic surface are respectively provided on both sides of the multiple sets of card holders. Two inserts are provided on the first magnetic surface, and two slots are provided on the second magnetic surface. The first magnetic surface and the second magnetic surface of the multiple sets of card holders are magnetically attracted to each other, and the two inserts are engaged with the two slots. Multiple sets of the first magnetic surface and the second magnetic surface can be magnetically attracted to each other and spliced ​​into an integrated structure, which facilitates joint inspection.

[0005] By adopting the above technical solution, and by setting up multiple card holders with first and second magnetic surfaces, along with inserts and slots, rapid and stable splicing of multiple card holders is achieved. This integrated structure significantly improves the convenience of parallel operation of the test cards and the overall structural stability, facilitating efficient batch sample inspection and simplifying the process.

[0006] Furthermore, a spring sleeve is provided on the top of the card holder, a spring groove is provided inside the spring sleeve, and a pressure plate is slidably connected inside the spring groove.

[0007] By adopting the above technical solution, the spring sleeve set on the top of the card holder, along with its internal spring groove and slidingly connected pressure plate, provides precise installation and movement space for the subsequent card locking mechanism, ensuring smooth and reliable locking action. This is a key basic structure for realizing convenient card fixing and release.

[0008] Furthermore, a spring is abutted on one side of the pressure plate, and a connecting rod is provided at the axis of the pressure plate, extending to the top of the spring sleeve and provided with a lever. A locking block is provided on the other side of the pressure plate, and the locking block extends into the slide groove.

[0009] By adopting the above technical solution, a complete locking and unlocking mechanism is formed by connecting the pressure plate, spring, connecting rod, lever, and locking block. The spring provides pre-pressure, causing the locking block to automatically engage with the detection card. Pushing the lever upwards will cause the pressure plate to retract against the spring force, thus unlocking the locking block. The operation is simple and quick.

[0010] Furthermore, the detection card includes a card body, and a card hole is provided at the top rear end of the card body.

[0011] By adopting the above technical solution, the detection card is defined to include the card body and the card hole set at its top and rear ends. The card hole is a key structure that cooperates with the locking mechanism block of the card housing device, providing the necessary interface for the accurate positioning and reliable fixation of the detection card in the card holder.

[0012] Furthermore, the card hole engages with the card block, and the upward movement of the lever can be used to unlock the detection card from the card housing device.

[0013] By adopting the above technical solution, the engagement of the card hole and the card block provides a mechanical locking point for the detection card, while the upward flicking of the lever provides a clear unlocking method. The operator only needs to perform a simple and clear "flicking" action to quickly release the locked state, which greatly improves the efficiency and convenience of loading and unloading the detection card.

[0014] Furthermore, the front end of the card holder is provided with a sliding groove, in which a detection card is engaged and slidably moved.

[0015] By adopting the above technical solution, a sliding groove is opened at the front end of the card holder, providing a clear and smooth sliding channel and precise positioning guidance for the insertion of the test card, ensuring that the test card can easily, quickly and accurately slide into the designated position of the card holder and maintain a stable posture.

[0016] Furthermore, a viewing port is provided at the top center of the card body, and the viewing port is a rectangular structure.

[0017] By adopting the above technical solution, a rectangular viewing port is opened in the middle of the top of the card body, providing the operator with a centrally located and regularly shaped observation window, ensuring that the reaction area of ​​the chromatography detection can be clearly and completely exposed in the field of view, which is convenient for accurate reading or automatic identification of the detection results by the instrument.

[0018] Furthermore, the top front end of the card body is provided with a drip inlet, and the edge of the drip inlet is provided with a chamfered structure.

[0019] By adopting the above technical solution, a drop inlet with a chamfered edge is set at the front end of the top of the card body. The chamfered design can significantly improve the flow characteristics of the droplet liquid, reduce the residue, hanging or splashing of the added sample at the edge of the inlet, and help the sample flow smoothly and completely into the interior of the test card, thereby improving the accuracy of the test.

[0020] In summary, the present invention has the following main advantages: This invention features a first magnetic surface, a plug, a second magnetic surface, a slot, a spring sleeve, a spring groove, a spring, a pressure plate, a locking block, a connecting rod, a lever, and a locking hole. Multiple card holders are magnetically connected via the first and second magnetic surfaces and securely linked by the plug and slot, forming an integrated structure for easy multi-unit testing. Simultaneously, the spring, pressure plate, and locking block within the spring sleeve engage with the locking hole on the top of the test card, enabling rapid card engagement and disengagement. The installation or removal of the test card can be easily accomplished by manipulating the lever. This solves the technical problems of traditional multi-unit test cards, which cannot quickly adapt to instrument readings, and whose installation and removal operations are cumbersome and lack stability, failing to meet the demands for efficient and accurate animal disease testing.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] A rapid-access detection card holder for animal disease chromatography, such as... Figure 1-4 As shown, the device includes a card holder 1 and a detection card 2. The card holder 1 includes multiple card holders 101. The multiple card holders 101 have a first magnetic surface 103 and a second magnetic surface 105 on both sides. The first magnetic surface 103 has two inserts 104, and the second magnetic surface 105 has two slots 106. The first magnetic surface 103 and the second magnetic surface 105 of the multiple card holders 101 are magnetically attracted to each other, and the two inserts 104 are engaged with the two slots 106. Multiple sets of first magnetic surfaces 103 and second magnetic surfaces 105 can be magnetically attracted and spliced ​​into an integrated structure, facilitating joint inspection. Utilizing the magnetic attraction of the first magnetic surfaces 103 and second magnetic surfaces 105 respectively located on both sides of the card holder 101, and with the physical snap-fit ​​formed by the two inserts 104 on the first magnetic surface 103 being inserted into the two slots 106 on the second magnetic surface 105, multiple card holders 101 can be quickly, accurately, and firmly spliced ​​into a single structure. This splicing ensures the structural strength and stability for joint use, providing an extremely convenient platform for batch sample loading and synchronous inspection. Operators can process multiple test cards 2 at once, significantly improving the efficiency of animal disease chromatography detection and simplifying the operation process.

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4A spring sleeve 107 is provided on the top of the card holder 101. A spring groove 108 is provided inside the spring sleeve 107. A pressure piece 110 is slidably connected inside the spring groove 108. The spring sleeve 107 on the top of the card holder 101 and the spring groove 108 inside it create a restricted movement path for the slidable pressure piece 110. The rigid structure of the spring sleeve 107 and the inner wall of the spring groove 108 play a precise guiding role for the movement of the pressure piece 110, ensuring that the pressure piece 110 can only slide in a straight line along a predetermined direction, usually perpendicular to the slide groove 102. This precise and stable movement channel is the key prerequisite for the subsequent spring 109 to drive the card block 111 to extend and engage the detection card 2, and for external force to drive the pressure piece 110 to retract and unlock through the lever 113. It fundamentally ensures the smooth execution of the locking and unlocking functions and the reliability of the operation.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 One side of the pressure plate 110 abuts against a spring 109, and a connecting rod 112 is provided at the axis of the pressure plate 110. The connecting rod 112 extends to the top of the spring sleeve 107 and is provided with a lever 113. A locking block 111 is provided on the other side of the pressure plate 110, and the locking block 111 extends into the slide groove 102. Under the continuous force of the spring 109, the pressure plate 110 naturally tends to push the locking block 111 connected to it toward the slide groove 102. When the detection card 2 is inserted into place, the locking block 111 automatically engages. Hole 204 forms a firm mechanical lock, effectively preventing the detection card 2 from accidentally slipping out. When it is necessary to remove the detection card 2, the operator only needs to push the lever 113 at the top of the connecting rod 112 upwards. This action is transmitted through the connecting rod 112 and directly drives the pressure plate 110 to overcome the elastic force of the spring 109 and slide along the spring groove 108, thereby completely pulling the card block 111 away from the card hole 204 and achieving instant unlocking. The entire unlocking process can be completed with one hand and the action is intuitive, simple and quick, which greatly facilitates the rapid replacement of the detection card 2.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4The detection card 2 includes a card body 201, and a card hole 204 is provided at the top rear end of the card body 201. The card hole 204 located at the top rear end of the card body 201 is a cleverly designed locking structure. Its position and size precisely correspond to the end point of the travel of the card block 111 near the end of the slide groove 102 on the card holder 101. When the detection card 2 is correctly and completely inserted into the card holder 101 along the slide groove 102, the card block 111 can be perfectly embedded in the card hole 204 under the drive of the spring 109. Through the physical interference between the edge of the card block 111 and the card hole 204, a reliable rigid connection point is established between the two, which firmly locks the detection card 2 in the working position of the card holder 101, effectively preventing the detection card 2 from shifting or loosening due to vibration or shaking during subsequent operations or equipment operation, and ensuring continuous and stable detection.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The card hole 204 engages with the card block 111, and the upward movement of the lever 113 can be used to unlock the detection card 2 from the card housing device 1. The successful engagement of the card hole 204 with the card block 111 indicates that the detection card 2 has been securely locked by the card holder 101 and is ready. This locking relationship ensures the stability of the detection process. When the detection card 2 needs to be replaced, the upward movement of the lever 113 located on the top of the spring sleeve 107 provides a clear, intuitive, and ergonomic unlocking operation command. This action directly acts on the drive mechanism connecting rod 112 and the pressure plate 110, instantly releasing the engagement between the card block 111 and the card hole 204, thus releasing the detection card 2. This design makes the unlocking action simple and easy to learn, requiring no complicated tools or great force, and can be easily completed with a single finger, making the disassembly process of the detection card 2 extremely efficient and user-friendly.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The front end of the card holder 101 is provided with a slide groove 102, in which the detection card 2 is engaged and slidably moved. The slide groove 102 at the front end of the card holder 101 serves as a dedicated track for accommodating and guiding the detection card 2. Its cross-sectional shape is highly matched with the relevant parts of the detection card 2, providing a clear and unobstructed sliding path for the insertion of the detection card 2. The inner wall of the slide groove 102 effectively limits and guides the detection card 2 in the left, right and up and down directions, ensuring that the detection card 2 can slide smoothly, quickly and accurately to its final working position with only a straight pushing action. At this position, it is held in a fixed posture by the constraint force of the slide groove 102 itself, without tilting or shaking, making the installation process simple and the positioning accurate and reliable.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The card body 201 has a viewing port 203 in the center of its top, and the viewing port 203 is rectangular. The rectangular viewing port 203, located in the center of the top of the card body 201, can fully and clearly expose the key chromatographic reaction area inside the test card 2, which usually includes the test line T and the control line C. Its rectangular structure means that the edges are straight, which maximizes the use of surface area to expose the effective interpretation area and provides a distortion-free field of view compared to circular or irregularly shaped windows. The central position design conforms to the visual focus position, which can easily and efficiently capture the complete reaction signal color lines whether it is manual visual interpretation or scanning by optical detection instruments, avoiding the interference of edge shadows or parallax on observation, and providing excellent visual interface support for the rapid and accurate judgment of animal disease detection results.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The card body 201 has a drop inlet 202 at its top front end. The edge of the drop inlet 202 is chamfered. The drop inlet 202 is located at the top front end of the card body 201. Its inlet edge is chamfered, such as a bevel or rounded. When liquid samples such as blood, serum, or tissue fluid are added, the chamfered structure can effectively eliminate the sharp edge effect and guide the falling or added liquid. This allows the droplets or liquid flow to flow more smoothly and without obstruction from the upper surface of the drop inlet 202 into the internal chromatography channel. This greatly reduces the risk of liquid adhering to the wall, accumulating, forming droplets, or even splashing at the inlet edge due to surface tension and other factors. It ensures that the predetermined volume of sample can be almost completely and quickly introduced into the core of the detection card 2 for reaction, avoiding poor chromatography effect or detection error caused by sample loss or insufficient addition, and improving the reliability and accuracy of animal disease chromatography detection.

[0032] The implementation principle of this embodiment is as follows: First, the operator brings multiple card holders 101 close to each other through the first magnetic surface 103 and the second magnetic surface 105, and uses the magnetic attraction to achieve adsorption connection. At the same time, the two inserts 104 on the first magnetic surface 103 are accurately inserted into the two slots 106 on the second magnetic surface 105 to lock them in place, thereby quickly splicing multiple sets of card holders 101 into a stable integrated structure, which is convenient for row inspection. Next, the test card 2 is slid into the slide groove 102 at the front end of the card holder 101. When the test card 2 is fully inserted, the pressure plate 110 in the spring sleeve 107 at the top of the card holder 101 is automatically pushed out by the sliding mechanism of the spring groove 108 under the pre-compression of the spring 109, and accurately inserted into the card hole 204 at the rear end of the test card 2, so as to achieve reliable fixation of the test card 2. When the test is completed or the test card 2 needs to be replaced, the operator moves the lever 113 upwards. The lever 113, through the connecting rod 112, causes the pressure plate 110 to slide inwards within the spring groove 108, compressing the spring 109. This causes the card block 111 to retract and exit from the card hole 204, unlocking the test card 2, which can then slide out along the slide groove 102 for subsequent processing. The entire process, through the coordinated action of the magnetic attraction, insertion, and spring locking mechanisms, ensures convenient installation, fixation, and removal of the test card 2. It also supports the parallel operation of multiple card holders 101, improving the efficiency and stability of animal disease chromatography testing.
