Abstract
Description
Technical Field
[0001] This utility model relates to the field of test strip boxes, specifically to an immunochromatographic test strip box with a pop-out test strip. Background Technology
[0002] Currently, most immunochromatographic test strips are stored in sealed boxes for long-term preservation. A new immunochromatographic test strip box includes a box body with a test strip cavity for holding stacked test strips. A paper outlet communicating with the test strip cavity is located on one side of the box body. A roller is rotatably mounted on the top of the test strip cavity, and a spring is fixed at the bottom. The spring pushes the stacked test strips upwards until they are firmly against the roller. To remove the strips, simply rotate the roller manually; the friction between the roller and the test strips will rotate and pull each strip out of the outlet, eliminating the need to open the box lid and significantly improving sealing to prevent moisture absorption. However, this immunochromatographic test strip box has the following technical problems in use:
[0003] The test strip box uses a spring and roller to separate the test strips smoothly. However, the separated test strips tend to deviate from the paper outlet and are difficult to move out of the narrow paper outlet smoothly. Furthermore, if the separated test strips cannot be completely moved out of the paper outlet, they are easily pushed and blocked by the next separated test strip, causing the test strip box to become clogged and the test strips to be damaged. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] This invention provides an immunochromatographic test strip cartridge with a pop-out test strip, which solves the problem of existing immunochromatographic test strip cartridges where it is difficult to smoothly remove the separated test strip from the paper outlet.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an immunochromatographic test strip cartridge with a pop-out test strip, comprising:
[0008] The box body has a test strip cavity inside, which is used to stack several test strips; and the box body has a paper outlet that communicates with the test strip cavity.
[0009] A test strip separation mechanism is provided inside the test strip cavity and is used to separate the test strips inside the test strip cavity one by one;
[0010] The paper outlet is movably disposed within the test paper cavity and can move between a closed position and a paper outlet position toward the paper outlet. The paper outlet is provided with a receiving groove for accommodating a single test paper.
[0011] An elastic element is disposed between the paper output board and the inner wall of the test paper cavity, and is used to drive the paper output board to move toward the paper output position.
[0012] A stop plate is located at the paper outlet of the box body;
[0013] In the closed position, the stop plate closes the paper outlet and abuts against the paper outlet plate, and the receiving groove connects with the paper outlet end of the test paper separation mechanism; in the paper outlet position, part of the paper outlet plate is located inside the test paper cavity and the other part is located outside the box, so as to move the test paper part in the receiving groove out of the paper outlet.
[0014] In a further configuration, the aforementioned test strip separation mechanism has symmetrical guide plates at the paper output end, and a guide channel is formed between the two guide plates that communicates with the receiving tank. The guide channel is used to guide the separated test strips into the receiving tank.
[0015] Further, the aforementioned test strip separation mechanism includes a roller, a lifting plate, and a lifting drive component. The roller is rotatably located at a right angle inside the test strip cavity and is positioned above one end of the lifting plate. An arc-shaped protrusion is integrally provided at the right angle inside the test strip cavity. The arc-shaped protrusion and the roller form an arc-shaped channel communicating with the guide channel. The lifting plate is movably located inside the test strip cavity, and the lifting drive component is fixed inside the test strip cavity and connected to the lifting plate. It is used to drive the lifting plate to rise, so as to push the stacked test strips inside the test strip cavity upward until they are in close contact with the roller.
[0016] Further configuration: the aforementioned roller includes a rigid body and an elastic ring block, the elastic ring block being sleeved on the outside of the rigid body, and the surface roughness of the elastic ring block being greater than the surface roughness of the rigid body.
[0017] Further, the aforementioned guide plate includes a first limiting part, a second limiting part, and a third limiting part. The first limiting part is axially fixed to one end of the roller to limit the left and right position of the test paper on the roller. The third limiting part is movably disposed on one side of the paper output board to limit the test paper from accurately entering the receiving groove. The two ends of the second limiting part are integrally connected to the first limiting part and the third limiting part, respectively.
[0018] Furthermore, a transparent observation plate is embedded in the top of the aforementioned box. When the cardboard is in the closed position, the transparent observation plate is positioned opposite the receiving slot.
[0019] (III) Beneficial Effects
[0020] Compared with the prior art, the immunochromatographic test strip cartridge with pop-out test strip provided by this utility model has the following beneficial effects:
[0021] 1. When using the immunochromatographic test strip cartridge with pop-out test strips provided by this utility model, the paper outlet is in the closed position. The test strip separation mechanism separates the stacked test strips in the test strip cavity one by one and inputs the separated test strips into the receiving groove that is connected to it. Then, the paper outlet is opened by the stop plate. At this time, the elastic element drives the paper outlet to move towards the paper outlet position so as to move the test strip part in the receiving groove out of the paper outlet, thereby smoothly removing the separated test strips from the paper outlet. In this way, the immunochromatographic test strip cartridge can solve the problem of existing immunochromatographic test strip cartridges that make it difficult to smoothly remove the separated test strips from the paper outlet.
[0022] 2. The immunochromatographic test strip box with pop-out test strips provided by this utility model can seal the paper outlet through the stop plate, thereby ensuring the airtightness of the test strip cavity and facilitating the long-term preservation of the test strips in the test strip cavity; and while the stop plate seals the paper outlet, the stop plate can also press tightly against the paper outlet plate, thereby restricting the paper outlet plate to the closed position and ensuring that the receiving groove is connected to the paper outlet end of the test strip separation mechanism.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Figure 4 This is a perspective view of the rollers, paper output plate, guide plate, and limiting plate in the embodiment.
[0030] An immunochromatographic test strip cartridge with pop-out test strips is provided to solve the problem of difficulty in smoothly removing the separated test strips 10 from the paper outlet 12 in existing immunochromatographic test strip cartridges 10.
[0031] The immunochromatographic test strip cartridge with pop-out test strips includes a cartridge body 1, a test strip separation mechanism 2, a paper dispensing plate 3, an elastic element 4, and a stop plate 5.
[0032] The box body 1 has a test strip cavity 11 inside, and a paper outlet 12 communicating with the test strip cavity 11 is opened on one side of the box body 1.
[0033] The test strip cavity 11 is used to stack multiple test strips 10.
[0034] The test strip separation mechanism 2 is installed inside the test strip cavity 11.
[0035] The test strip separation mechanism 2 is used to separate the test strips 10 in the test strip cavity 11 one by one and output the separated single test strips 10.
[0036] The paper output board 3 is movably installed inside the test paper cavity 11 and can move between the closed position and the paper output position towards the paper output port 12. The top of the paper output board 3 has a receiving groove 31.
[0037] The aforementioned receiving groove 31 is used to receive a single test strip 10 separated by the test strip separation mechanism 2.
[0038] The elastic element 4 is installed between the paper output plate 3 and the inner wall of the test paper cavity 11.
[0039] The aforementioned elastic element 4 can be a spring, which is elastic and can automatically drive the paperboard 3 to move toward the paper output position.
[0040] The stop plate 5 is installed at the paper outlet 12 of the box body 1.
[0041] The aforementioned stop plate 5 can seal the paper outlet 12, thereby ensuring the airtightness of the test paper cavity 11, which is beneficial for the long-term preservation of the test paper 10 in the test paper cavity 11; at the same time, the stop plate 5 can also restrict the paper outlet 3 to a closed position, ensuring that the receiving groove 31 is connected to the paper outlet end of the test paper separation mechanism 2.
[0042] When the paper output plate 3 is in the closed position, the stop plate 5 closes the paper output port 12 and abuts against the paper output plate 3. The receiving groove 31 is connected to the paper output end of the test paper separation mechanism 2 so that the test paper 10 separated by the test paper separation mechanism 2 is located in the receiving groove 31. When the paper output plate 3 is in the paper output position, part of the paper output plate 3 is located in the test paper cavity 11 and the other part is located outside the box body 1 so as to move part of the test paper 10 in the receiving groove 31 out of the paper output port 12.
[0043] The above-described immunochromatographic test strip cartridge with pop-out test strips separates the stacked test strips 10 in the test strip cavity 11 one by one through the test strip separation mechanism 2, and inputs the separated test strips 10 into the receiving groove 31 that is connected to it. Furthermore, the elastic element 4 and the stop plate 5 cooperate to control the displacement of the paper outlet 3 from the closed position toward the paper outlet position, so as to move part of the test strips 10 in the receiving groove 31 out of the paper outlet 12, thereby smoothly removing the separated test strips 10 from the paper outlet 12. In this way, the immunochromatographic test strip cartridge with pop-out test strips can solve the problem of existing immunochromatographic test strip cartridges having difficulty in smoothly removing the separated test strips 10 from the paper outlet 12.
[0044] To ensure that the test strips 10 separated by the test strip separation mechanism 2 can be smoothly moved into the receiving tank 31, guide plates 6 are symmetrically installed at the paper output end of the test strip separation mechanism 2, and a guide channel 7 is formed between the two guide plates 6. When the paper output plate 3 is in the closed position, the paper output end of the guide channel 7 is connected to the receiving tank 31. The guide channel 7 is used to guide the separated test strips 10 into the receiving tank 31.
[0045] In one embodiment of the test strip separation mechanism 2, the test strip separation mechanism 2 includes a roller 21, a lifting plate 22, and a lifting drive 23. The roller 21 is rotatably mounted at a right angle inside the test strip cavity 11 and is located above one end of the lifting plate 22. One end of the roller 21 extends out of the housing 1 and can be manually driven to rotate. An arc-shaped protrusion 111 is integrally formed at the right angle inside the test strip cavity 11. The arc-shaped protrusion 111 and the outer surface of the roller 21 form an arc-shaped channel 8. The arc-shaped channel 8 and the outer surface of the roller 21 form an arc-shaped channel 8. The paper feed end of the guide channel 7 is connected to guide the separated test strips 10 into the guide channel 7; the lifting plate 22 is movably installed in the test strip cavity 11, and the lifting drive 23 can use a spring. The bottom end of the spring is bonded to the inner wall of the test strip cavity 11, and the top end of the spring is bonded to the bottom surface of the lifting plate 22. In this way, the lifting drive 23 drives the lifting plate 22 to rise through the elastic force, and at the same time pushes all the test strips 10 in the test strip cavity 11 upward, so that the stacked test strips 10 in the test strip cavity 11 can be pushed upward until they are in close contact with the roller 21. When the test strip separation mechanism 2 is in use, the roller 21 is rotated, and the roller 21 separates the top layer of test strip 10 from the other test strips 10 through friction. At the same time, the separated test strip 10 is fed into the guide channel 7 through the arc-shaped channel 8. When the roller 21 separates and moves the test strip 10 through friction, the arc-shaped protrusion 111 can ensure that the separated test strip 10 smoothly enters the guide channel 7 through the arc-shaped channel 8, avoiding the test strip 10 from getting stuck at the right angle in the test strip cavity 11 during the movement.
[0046] In one embodiment of the roller 21, the roller 21 includes a rigid body 211 and an elastic ring block 212. The rigid body 211 is in the shape of a stepped shaft and can be made of metal. The elastic ring block 212 is tightly fitted around the outer side of the middle part of the rigid body 211 and can be made of elastic rubber material, so that the surface roughness of the elastic ring block 212 is greater than the surface roughness of the rigid body 211. In this way, the elastic ring block 212 can increase the surface friction of the roller 21, so that the roller 21 can easily drive the test paper 10 that it is in contact with during rotation, thereby achieving the function of separating the test paper 10, and driving the separated test paper 10 into the arc-shaped channel 8 and the guide channel 7 in sequence, and finally fall into the receiving groove 31.
[0047] In one embodiment of the elastic ring block 212, a plurality of protrusions (not shown in the figure) are evenly distributed on the outer peripheral wall of the elastic ring block 212, or complex patterns may be distributed on the outer peripheral wall of the elastic ring block 212 to make the outer surface of the elastic ring block 212 rougher, thereby further increasing the surface friction of the roller 21.
[0048] In one embodiment of the guide plate 6, the guide plate 6 includes a first limiting part 61, a second limiting part 62, and a third limiting part 63. The first limiting parts 61 of the two guide plates 6 are axially fixed to both ends of the roller 21 by square limiting blocks. The third limiting parts 63 of the two guide plates 6 are located on both sides of the paper output plate 3 to restrict the test paper 10 from accurately entering the receiving groove 31. The two ends of the second limiting part 62 are integrally connected to the first limiting part 61 and the third limiting part 63, respectively. In this way, the first limiting parts 61 of the two guide plates 6 cooperate to restrict the left and right position of the test paper 10 on the roller 21, ensuring that the test paper 10 can smoothly enter the guide channel 7 from the arc-shaped channel 8. The third limiting parts 63 of the two guide plates 6 cooperate to restrict the test paper 10 in the guide channel 7 to fall completely into the receiving groove 31.
[0049] When the paperboard 3 is in the closed position, it is located on one side of the roller 21. To ensure that the test strip 10 enters the guide channel 7 from the arc-shaped channel 8, a limiting plate 9 is welded between the two guide plates 6. One end of the limiting plate 9 is tangent to the outer peripheral wall of the elastic ring block 212, and the other end is parallel and located above the paperboard 3. In this way, the limiting plate 9 can prevent the test strip 10 from rotating with the roller 21 into the space between the roller 21 and the paperboard 3, and guide the test strip 10 to move directly along the limiting plate 9 towards the guide channel 7. In addition, the limiting plate 9 does not block the opening of the receiving groove 31, so as to prevent the test strip 10 from falling completely into the receiving groove 31.
[0050] To facilitate the movement of the paper dispenser 3 between the closed position and the paper dispensing position along the test paper cavity 11, symmetrical sliding recesses 32 are provided on both sides of the paper dispenser 3. The side walls of the test paper cavity 11 are integrally formed with sliding protrusions 112 that slide in conjunction with the sliding recesses 32. Thus, through the sliding engagement of the sliding protrusions 112 and the sliding recesses 32, the paper dispenser 3 can smoothly slide along the test paper cavity 11 to either the closed position or the paper dispensing position, making it convenient to use.
[0051] To ensure that users can observe whether the test strip 10 separated by the test strip separation mechanism 2 has completely fallen into the receiving groove 31, a transparent observation plate 13 is embedded in the top of the box body 1. When the dispensing plate 3 is in the closed position, the transparent observation plate 13 is opposite to the receiving groove 31. In this way, the transparent observation plate 13 allows users to easily observe the separation process and ensure that the test strip 10 has completely fallen into the receiving groove 31 before switching the dispensing plate 3 to the paper dispensing position. This prevents the test strip 10 from being moved out of the paper outlet 12 with the dispensing plate 3 before it has completely fallen into the receiving groove 31, which could cause the test strip 10 to block the paper outlet 12.
[0052] To prevent the stop plate 5 from detaching from the tray 1 at the paper output position, one side of the stop plate 5 is rotatably connected to the tray 1 via a pivot, while the other side is detachably connected to the tray 1. This ensures that the stop plate 5 is always connected to the tray 1, preventing it from being lost after the paper output port 12 is opened, and also facilitating opening and closing.
[0053] In one detachable installation method of the stop plate 5 and the box body 1, the box body 1 has a slot 14 communicating with the paper outlet 12, and a locking part 51 that engages with the slot 14 is integrally connected to one side of the stop plate 5. Thus, when the stop plate 5 rotates to the closed position, the locking part 51 rotates and moves into the slot 14, engaging with the slot 14, thereby quickly and detachably connecting the stop plate 5 and the box body 1. Conversely, when the locking part 51 disengages from the slot 14, the connection between the stop plate 5 and the box body 1 on one side is released, and the stop plate 5 is driven by the paper outlet 3 to rotate outward to the paper outlet position.
[0054] How to use:
[0055] When using the immunochromatographic test strip cassette with pop-out test strips provided by this utility model, the original position of the dispensing plate 3 is in the closed position. First, manually rotate the roller 21. The roller 21 drives the uppermost test strip 10, which is in contact with it, to move through friction. The uppermost test strip 10 enters the arc-shaped channel 8 and the guide channel 7 in sequence, separates from the other test strips 10, and falls completely into the receiving groove 31. Then, disengage the locking part 51 from the locking slot 14. The elastic member 4 pops the dispensing plate 3 out of the cassette 1 to the paper dispensing position, and the paper is dispensed. As plate 3 slides, stop plate 5 rotates outward to open paper outlet 12, allowing test paper 10 in receiving slot 31 to move out of paper outlet 12 along with part of paper outlet plate 3. Then, the user completely pulls the test paper 10 out of paper outlet 12 through the part of the test paper 10 that has moved out of paper outlet 12. After the test paper 10 in receiving slot 31 is pulled out, compression elastic element 4 moves paper outlet plate 3 back into box 1, returning paper outlet plate 3 to the closed position. Finally, stop plate 5 is rotated to engage locking part 51 with locking slot 14 to close test paper cavity 11. This process is repeated to eject test paper 10 one by one from paper outlet 12.
