Abstract
Description
Technical Field
[0001] This utility model relates to the field of antigen detection technology, and in particular to a rapid antigen detection reagent platform with multiple parallel channels. Background Technology
[0002] Currently, vaccination has become an important means of controlling diseases in the aquaculture industry, and routine monitoring of antibodies produced after vaccination has also become an important means of detecting disease incidence.
[0003] Chinese utility model patent CN220584229U discloses a saliva detection device for swine disease antigens. In use, this device uses multiple sets of dropper tubes mounted on a fixed base. With the help of multiple soft pads, the solvent in each dropper tube is squeezed onto the corresponding test strip below, thus achieving multi-channel parallel detection and improving detection efficiency. However, this device has certain drawbacks in practical use. For example, the dropper tubes need to be removed and replaced one by one after use, significantly reducing efficiency. Therefore, this paper proposes a multi-channel parallel rapid antigen detection reagent platform to address these issues. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-channel parallel rapid antigen detection reagent platform.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-channel parallel rapid antigen detection reagent platform includes a base. The upper end of the base has a placement slot, and a detection plate is slidably connected inside. Multiple test strip placement slots are formed on the end face of the detection plate. A rotating rod is rotatably connected to the upper end of the base. A side plate is fixedly connected to the upper end of the base, and a top seat is fixedly connected to the end of the side plate. The end of the rotating rod is rotatably connected to the top seat. Two sets of fixing seats are fixedly connected to the outer wall of the rotating rod, with an included angle of 90 degrees between the two sets of fixing seats. Multiple placement holes are formed through the end face of the fixing seats, corresponding one-to-one with the positions of the test strip placement slots. Multiple insertion holes are formed on the side wall of the fixing seats, extending into each placement hole. A fixing plate is slidably connected to the outside of the fixing seat, and multiple top rods are fixedly connected to the outer wall of the fixing plate, each inserting into a corresponding insertion hole. A movable mechanism is installed on the upper end of the top seat to drive the fixing plate to move up and down.
[0007] Preferably, the movable mechanism includes a reciprocating screw rotatably connected to the upper end of the top seat and fixedly connected coaxially with the rotating rod. A slider is threadedly connected to the threaded section of the reciprocating screw. A connecting rod is fixedly connected to the outer wall of the slider, and a sliding plate is fixedly connected to the end of the connecting rod. Two sets of sliding rods are slidably connected to the outer wall of the sliding plate, and the ends of both are fixedly connected to the fixed plate.
[0008] Preferably, a connecting plate is fixedly connected to the end of each set of sliding rods away from the slide plate, and a spring is sleeved on the outer wall of each set of sliding rods, with the two ends of the spring being fixedly connected to the slide plate and the connecting plate, respectively.
[0009] Preferably, a limiting rod is fixedly connected to the upper end of the top seat, and the slider is slidably connected to the outer wall of the limiting rod.
[0010] Preferably, a limiting block is fixedly connected to the end of the reciprocating lead screw, and the radius of the limiting block is larger than the radius of the reciprocating lead screw.
[0011] Preferably, a servo motor is fixedly connected to the lower end face of the base, and the output shaft of the servo motor is fixedly connected to the rotating rod coaxially.
[0012] This utility model has the following beneficial effects:
[0013] 1. This utility model sets up two sets of fixed seats and rotating rods with a 90-degree included angle. After one set of fixed seats completes the dripping, the servo motor drives the rotating rod to rotate 90 degrees to quickly switch to another set of fixed seats with pre-installed drip heads, realizing uninterrupted continuous detection. This avoids the inefficiency caused by the need to disassemble and assemble drip heads one by one in traditional devices, and improves the speed of large-scale sample detection.
[0014] 2. This utility model uses a reciprocating screw to drive the slide plate and the top rod to rise and fall synchronously, avoiding conflict with the rotation of the slide plate. Combined with the elastic buffering effect of the spring, multiple sets of top rods can apply force to squeeze the dripping head evenly, ensuring that the dripping volume of each channel is consistent.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-3 A multi-channel parallel rapid antigen detection reagent platform includes a base 1, with a placement slot at the upper end of the base 1 and a detection plate 6 slidably connected inside. Multiple test strip placement slots 7 are opened on the end face of the detection plate 6. A rotating rod 4 is rotatably connected to the upper end of the base 1. A side plate 2 is fixedly connected to the upper end of the base 1, and a top seat 3 is fixedly connected to the end of the side plate 2. The end of the rotating rod 4 is rotatably connected to the top seat 3. Two sets of fixing seats 5 are fixedly connected to the outer wall of the rotating rod 4. The included angle between the two sets of fixing seats 5 is 90 degrees. Multiple placement holes 14 are opened through the end face of the fixing seat 5, and they correspond one-to-one with the positions of the test strip placement slots 7. Multiple sets of insertion holes 13 are opened on the side wall of the fixing seat 5 and extend into each set of placement holes 14. A fixing plate is slidably connected to the outside of the fixing seat 5, and multiple sets of top rods 16 are fixedly connected to the outer wall of the fixing plate and are inserted into the corresponding insertion holes 13. An active mechanism for driving the fixing plate to move up and down is installed on the upper end of the top seat 3.
[0021] Furthermore, by rotating the two sets of fixed seats 5 alternately to the detection position, after one set of fixed seats 5 has finished dispensing, the other set of fixed seats 5 can be pre-installed with a new drip head module, realizing continuous and rapid replacement and avoiding the efficiency reduction caused by disassembling and assembling each set of drip heads one by one.
[0022] The moving mechanism includes a reciprocating screw 8 rotatably connected to the upper end of the top seat 3 and coaxially fixedly connected to the rotating rod 4. A slider 10 is threadedly connected to the threaded section of the reciprocating screw 8. A connecting rod 15 is fixedly connected to the outer wall of the slider 10, and a slide plate 12 is fixedly connected to the end of the connecting rod 15. Two sets of slide rods 17 are slidably connected to the outer wall of the slide plate 12, and the ends of both sets of slide rods 17 are fixedly connected to the fixed plate. A connecting plate 18 is fixedly connected to the end of the two sets of slide rods 17 away from the slide plate 12. A spring 19 is sleeved on the outer wall of the two sets of slide rods 17, and the two ends of the spring 19 are fixedly connected to the slide plate 12 and the connecting plate 18, respectively.
[0023] Furthermore, by rotating the reciprocating screw 8 to drive the push rod 16 to rise and fall synchronously, the positions of the slide plate 12, connecting plate 18 and fixing plate can be avoided from affecting the rotation of the fixing seat 5. When one set of fixing seats 5 rotates to 45 degrees, the slider 10 slides to the top of the reciprocating screw 8 and then slides down to the bottom, ensuring that the push rod 16 can be aligned with the position of the insertion hole 13.
[0024] A limiting rod 9 is fixedly connected to the upper end of the top seat 3, and a slider 10 is slidably connected to the outer wall of the limiting rod 9. A limiting block 11 is fixedly connected to the end of the reciprocating screw 8, and the radius of the limiting block 11 is larger than the radius of the reciprocating screw 8.
[0025] Furthermore, the limiting rod 9 constrains the movement path of the slider 10 to prevent the slider 10 from deviating when the reciprocating screw 8 rotates.
[0026] A servo motor 20 is fixedly connected to the lower end face of the base 1, and the output shaft of the servo motor 20 is fixedly connected to the rotating rod 4 coaxially.
[0027] In this invention, the device is used as follows: When the operator uses the multi-channel parallel rapid antigen detection reagent platform, the detection plate 6 is pre-inserted into the placement slot of the base 1, and multiple sets of test strips are placed in the test strip placement slot 7. After the servo motor 20 is started, the rotating rod 4 drives the two sets of fixed seats 5 to rotate synchronously, and the reciprocating screw 8 rotates coaxially with the rotating rod 4. When the fixed seat 5 rotates to the detection position, the multiple sets of top rods 16 are now aligned with the multiple sets of insertion holes 13. Then, the connecting plate 18 is pulled outward, the spring 19 is compressed and then released. After the spring 19 is subjected to the restoring force, it drives the fixed plate to slide towards the insertion hole 13, so that the top rod 16 is inserted into the insertion hole 13 and squeezes the bottom of the dropper, so that the liquid is evenly dripped onto the test strip in the test strip placement slot 7 below, completing the multi-channel parallel liquid dripping.
[0028] After the dripping is completed, the servo motor 20 continues to drive the rotating rod 4 to rotate 90 degrees, causing the other set of fixed seats 5 in the idle position to switch to the detection position. During this process, the limit block 11 of the reciprocating screw 8 restricts the stroke of the slider 10, ensuring that the slider 10 automatically slides in the reverse direction when it moves to the highest point. After the fixed seat 5 in the original detection position rotates to the designated position, the operator can quickly remove the used dripping head module and replace it with a new module. The newly positioned fixed seat 5 can immediately perform the next round of dripping operation, realizing the alternating and continuous use of the two sets of dripping head modules.
[0029] In summary, this device effectively solves the problem of low efficiency in the prior art of replacing droppers one by one by alternating detection with dual fixed seats 5 and the up-and-down movement of the reciprocating screw 8 and sliding plate 12, while ensuring the consistency and accuracy of multi-channel dispensing. It is suitable for rapid antigen detection scenarios with large-scale samples.
[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
