Description

Technical Field

[0001] This invention relates to the field of detection instrument technology, specifically a chemiluminescence immunoassay analyzer detection device. Background Technology

[0002] Chemiluminescence immunoassay is an analytical technique that combines highly sensitive chemiluminescence assay with highly specific immunoassay.

[0003] Chemiluminescence immunoassay primarily relies on an immunoreaction system and a chemiluminescence analysis system. The immunoreaction system utilizes the specific binding between antigens and antibodies to form antigen-antibody complexes, thereby recognizing and capturing the analyte. In chemiluminescence immunoassay, luminescent substances are typically attached as labels to antigens or antibodies. When antigens and antibodies bind to form complexes, the luminescent substances also aggregate. Under specific conditions, these luminescent substances undergo a chemical reaction, releasing energy and generating a light signal. The intensity of the light signal is directly proportional to the concentration of the analyte; therefore, the concentration of the analyte can be indirectly determined by measuring the intensity of the light signal. Based on the different chemiluminescent substances labeled on antigens and antibodies and their corresponding excitation substrates, chemiluminescence is divided into two main types: direct luminescence and indirect luminescence. Direct luminescence typically involves labeling antigens and antibodies with chemicals such as acridinium esters and luminol, requiring a corresponding substrate for excitation. Indirect luminescence typically involves labeling antigens and antibodies with alkaline phosphatase or horseradish peroxidase, requiring their corresponding substrates for excitation.

[0004] Currently, commercially available chemiluminescence immunoassay analyzers typically use only one type of luminescence, either direct or indirect. This makes it impossible to perform simultaneous detection of both types on a single instrument, requiring two separate machines, which is extremely inconvenient for clinical use and significantly increases equipment costs. Therefore, there is a strong need to improve existing instruments to enable simultaneous detection of both direct and indirect luminescence types on a single machine. Current instruments use a single device for substrate dispensing, only capable of dispensing substrates for one type of luminescence, and cannot automatically switch between substrates for both methods. This limits the current technology to only one type of detection. Therefore, an improved device is needed to address these issues. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides a chemiluminescence immunoassay analyzer detection device.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: a chemiluminescence immunoassay analyzer detection device, comprising a base plate, a motor base plate fixedly installed at the top of the base plate, a motor fixedly installed at the bottom of the motor base plate, a waste liquid multi-channel substrate tube connector installed at the bottom of the motor base plate away from the motor, a multi-channel substrate dispensing arm fixedly installed at the top of the motor, a light-shielding multi-channel substrate tube connector fixedly installed at the top of the multi-channel substrate dispensing arm near the top of the motor, a multi-channel substrate pressure plate installed on the light-shielding multi-channel substrate tube connector, a panel installed at the top of the multi-channel substrate pressure plate, a trigger plate fixedly installed at the end of the multi-channel substrate dispensing arm near the light-shielding multi-channel substrate tube connector, and a slotted photoelectric sensor installed at the top of the motor base plate.

[0007] Specifically, the motor base plate also includes a displacement device, which is fixedly installed at the rear end of the motor base plate. The displacement device includes a connecting square rod, a side end support plate, and a magnetic suction plate. The side end support plate is fixedly installed on the left side of the connecting square rod, and the magnetic suction plate is fixedly installed on the top end of the side end support plate. An iron plate is slidably inserted into the side end of the side end support plate away from the connecting square rod. A plastic disc is fixedly installed at the rear end of the iron plate, and an alignment plate is fixedly installed at the top end of the iron plate.

[0008] When the connecting rod drives the alignment plate to contact the limiting partition, the iron plate can be displaced on the side end of the side support plate.

[0009] Specifically, a transmission gear is fixedly installed on the top of the motor, a first rack and a second rack are slidably inserted into the bottom of the motor base plate, a second connecting rod is fixedly installed at the end of the first rack away from the transmission gear, a third connecting rod is fixedly installed at the rear end of the second rack, a hexagonal rod is slidably inserted into the rear end of the third connecting rod, a first connecting rod is fixedly installed on the side end of the hexagonal rod, and a return spring is fixedly installed between the first connecting rod and the third connecting rod, with the return spring located on the outer ring of the hexagonal rod.

[0010] When the motor starts, it can drive the transmission gear to rotate, so that the first rack and the second rack can be displaced simultaneously.

[0011] Specifically, the base plate includes a conveying device, an alignment device, an extension top frame, and a limiting partition. The alignment device is fixedly installed at the bottom rear end of the base plate, the conveying device is rotatably installed inside the alignment device, the extension top frame is symmetrically fixedly installed at the top end of the alignment device, and the limiting partition is fixedly installed at the front end of the extension top frame.

[0012] Specifically, the conveying device includes a rotating disk, a plastic ring, and a support shaft. The support shaft is fixedly installed at the bottom center of the rotating disk, and the plastic ring is fixedly installed on the outer ring of the rotating disk.

[0013] Specifically, the alignment device includes a support base, a conveying pipe, and a support chassis. The support base is fixedly installed at the rear end of the base plate, the conveying pipe is fixedly installed at the rear end of the support base, and the support chassis is fixedly installed at the top rear end of the support base, with the support chassis located below the conveying pipe. A guide cavity is fixedly installed at the bottom right side of the support chassis. A push plate is slidably inserted into the left side of the guide cavity, and a movable rod is fixedly installed on the left side of the push plate.

[0014] When the first connecting rod is displaced, it can drive the push plate to move inside the guide cavity through the movable rod.

[0015] Specifically, the support shaft is rotatably mounted on the top of the support base, and the bottom end of the rotating disk is in contact with the inner bottom end of the support chassis. The rear end of the first connecting rod is connected to the front end of the movable rod, and the rear end of the second connecting rod is connected to the front end of the connecting square rod away from the alignment plate.

[0016] Specifically, both ends of the alignment plate are inclined at 45° and are aligned with the limiting partitions. The front-to-back distance between the two limiting partitions is 5 cm. The width of the alignment plate is 5 cm. Insert rods are symmetrically fixed between the push plate and the movable rod, and the insert rods penetrate the interior of the guide cavity.

[0017] Specifically, the iron plate is fixedly equipped with keying on the side end near the side support plate and the top of the first and second racks. The bottom end of the motor base plate and the side end of the side support plate away from the connecting square rod are provided with slots. The first and second racks mesh with the transmission gears. The top of the rotating disk is in contact with the bottom of the inner end of the conveying pipe.

[0018] Specifically, the supporting chassis has a square groove on the side near the guide cavity, the rotating disk has a circular hole inside, the circular holes are arranged in a ring, the push plate is L-shaped, and the conveying pipe has a through hole inside.

[0019] The beneficial effects of this invention are:

[0020] First, this invention allows plastic storage bottles to be stacked and placed inside the conveying pipe, enabling them to accurately enter the rotating disk. Simultaneously, when the multi-channel substrate dispensing arm rotates, it drives the transmission gear, causing the first rack to displace. This allows the plastic tray to pass over the surface of the plastic ring, causing the rotating disk to rotate. Furthermore, when the rotating disk is not receiving plastic storage bottles, it can block the bottom of the conveying pipe, preventing the plastic storage bottles from falling prematurely, thus completing the cyclical supply of plastic storage bottles.

[0021] Second, when the transmission gear rotates, it can drive the second rack to move, so that the second rack can drive the movable rod to move towards the guide cavity through the third connecting rod and the first connecting rod. When the rotating disk rotates, the plastic storage bottle can fall into the interior of the guide cavity. When the movable rod moves, it can drive the push plate to push the plastic storage bottle that has fallen into the guide cavity to the end away from the supporting base, thus completing the work of discharging the plastic storage bottle one by one.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] The invention will be further described below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1 As shown, a chemiluminescence immunoassay analyzer detection device of the present invention includes a base plate 7, a motor base plate 1 fixedly installed at the top of the base plate 7, a motor 9 fixedly installed at the bottom of the motor base plate 1, a waste liquid multi-channel substrate tube connector 5 installed at the bottom of the motor base plate 1 away from the motor 9, a multi-channel substrate dispensing arm 2 fixedly installed at the top of the motor 9, a light-shielding multi-channel substrate tube connector 8 fixedly installed at the top of the multi-channel substrate dispensing arm 2 near the top of the motor 9, a multi-channel substrate pressure plate 3 installed on the light-shielding multi-channel substrate tube connector 8, a panel 6 installed at the top of the multi-channel substrate pressure plate 3, a trigger plate 4 fixedly installed at the end of the multi-channel substrate dispensing arm 2 near the light-shielding multi-channel substrate tube connector 8, and a slotted photoelectric sensor 10 installed at the top of the motor base plate 1.

[0038] The working principle of Example 1 is as follows: During use, the pump body is connected to the light-proof multi-channel substrate tube connector 8 through an external pump body pipe, and the slotted photoelectric sensor 10 is electrically connected to the external pump body. An external storage bottle can be placed at the rear end of the base plate 7. Then, the motor 9 is started, driving the multi-channel substrate dispensing arm 2 to rotate. When the multi-channel substrate dispensing arm 2 rotates, it can move the trigger plate 4 into the groove inside the slotted photoelectric sensor 10, thus triggering the slotted photoelectric sensor 10 to start the external pump body. At this time, the pump body can deliver substrate into the interior of the light-proof multi-channel substrate tube connector 8. When the trigger plate 4 enters the slotted photoelectric sensor... When the electric sensor 10 is inside, the multi-channel substrate dispensing arm 2 can be vertically aligned with the top of the storage bottle at the rear end of the base plate 7. This allows the multi-channel substrate dispensing arm 2 to drip substrate into the storage bottle when the pump is started, completing the substrate input into the storage bottle. Subsequently, when the motor 9 is started again, it can drive the multi-channel substrate dispensing arm 2 to rotate in the opposite direction, so that the outlet at the bottom of the multi-channel substrate dispensing arm 2 is vertically aligned with the waste liquid multi-channel substrate pipe connector 5, allowing the waste liquid to be discharged from the waste liquid multi-channel substrate pipe connector 5. At the same time, when the trigger piece 4 is moved out of the inside of the slot-shaped photoelectric sensor 10, the external pump can be de-energized, the substrate dispensing stops, and the work is completed.

[0039] Example 2

[0040] Based on Example 1, such as Figure 2 , Figure 3 and Figure 4 As shown, the motor base plate 1 also includes a displacement device 11, which is fixedly installed at the rear end of the motor base plate 1. The displacement device 11 includes a connecting square rod 18, a side end support plate 17, and a magnetic suction plate 13. The side end support plate 17 is fixedly installed on the left side of the connecting square rod 18, and the magnetic suction plate 13 is fixedly installed on the top end of the side end support plate 17. An iron plate 14 is slidably inserted into the side end of the side end support plate 17 away from the connecting square rod 18. A plastic disc 15 is fixedly installed at the rear end of the iron plate 14, and an alignment plate 16 is fixedly installed at the top end of the iron plate 14.

[0041] When the connecting rod 18 drives the alignment plate 16 to contact the limiting partition 30, the iron plate 14 can be displaced on the side end of the side support plate 17.

[0042] like Figure 5 , Figure 6 and Figure 7A transmission gear 21 is fixedly installed on the top of the motor 9. A first rack 22 and a second rack 12 are slidably inserted into the bottom of the motor base plate 1. A second connecting rod 20 is fixedly installed at the end of the first rack 22 away from the transmission gear 21. A third connecting rod 25 is fixedly installed at the rear end of the second rack 12. A hexagonal rod 23 is slidably inserted into the rear end of the third connecting rod 25. A first connecting rod 19 is fixedly installed on the side end of the hexagonal rod 23. A return spring 26 is fixedly installed between the first connecting rod 19 and the third connecting rod 25. The return spring 26 is located on the outer ring of the hexagonal rod 23. By setting the limiting rod 24, when the third connecting rod 25 moves to the left, it can drive the limiting rod 24 to squeeze the first connecting rod 19 to move.

[0043] When the motor 9 starts, it can drive the transmission gear 21 to rotate, so that the first rack 22 and the second rack 12 can be displaced at the same time.

[0044] like Figure 8 The base plate 7 includes a conveying device 27, an alignment device 28, an extension top frame 29, and a limiting partition 30. The alignment device 28 is fixedly installed at the bottom rear end of the base plate 7. The conveying device 27 is rotatably installed inside the alignment device 28. The extension top frame 29 is symmetrically fixedly installed at the top of the alignment device 28. The limiting partition 30 is fixedly installed at the front end of the extension top frame 29. The two limiting partitions 30 are both set in an arc state at opposite ends, and the right limiting partition 30 is located in front of the left limiting partition 30, so that when the second connecting rod 20 moves left and right, the iron plate 14 can be driven forward or backward by the alignment plate 16.

[0045] like Figure 9 The conveying device 27 includes a rotating disk 31, a plastic ring 32, and a support shaft 33. The support shaft 33 is fixedly installed at the bottom center of the rotating disk 31, and the plastic ring 32 is fixedly installed on the outer ring of the rotating disk 31. When the rotating disk 31 rotates, it can drive the round hole inside the rotating disk 31 to be vertically aligned with the top of the guide cavity 36, so that the plastic storage bottle can fall into the interior of the guide cavity 36.

[0046] like Figure 10The alignment device 28 includes a support base 39, a conveying pipe 34, and a support chassis 37. The support base 39 is fixedly installed at the rear end of the base plate 7, the conveying pipe 34 is fixedly installed at the rear end of the support base 39, and the support chassis 37 is fixedly installed at the top rear end of the support base 39, with the support chassis 37 located below the conveying pipe 34. A guide cavity 36 is fixedly installed at the bottom right side of the support chassis 37. A push plate 35 is slidably inserted into the left side of the guide cavity 36, and a movable rod 38 is fixedly installed on the left side of the push plate 35. When the rotating disk 31 drives the circular hole to rotate until it aligns with the through hole inside the conveying pipe 34, the plastic storage bottle will fall into the circular hole inside the rotating disk 31. The height of each plastic storage bottle is the same as the height of the circular hole inside the rotating disk 31, so that the rotating disk 31 can only take away one plastic storage bottle when it rotates.

[0047] When the first connecting rod 19 is displaced, it can drive the push plate 35 to move inside the guide cavity 36 through the movable rod 38.

[0048] The support shaft 33 is rotatably mounted on the top of the support base 39, and the bottom end of the rotating disk 31 is in contact with the inner bottom end of the support base 37. The rear end of the first connecting rod 19 is connected to the front end of the movable rod 38, and the rear end of the second connecting rod 20 is connected to the front end of the connecting square rod 18 away from the alignment plate 16. Both ends of the alignment plate 16 are inclined at 45°, and both ends of the alignment plate 16 are aligned with the limiting partition 30. The front-to-back distance between the two limiting partitions 30 is 5 cm, and the width of the alignment plate 16 is 5 cm. Insert rods are symmetrically fixed between the push plate 35 and the movable rod 38, and the insert rods penetrate the guide cavity. Inside 36, the iron plate 14 near the side end of the side support plate 17 and the top of the first rack 22 and the second rack 12 are all fixedly installed with key. The bottom end of the motor base plate 1 and the side end of the side support plate 17 away from the connecting square rod 18 are both provided with slots. The first rack 22 and the second rack 12 are both meshed with the transmission gear 21. The top of the rotating disk 31 is in contact with the bottom of the inside of the conveying pipe 34. The side end of the support base 37 near the guide cavity 36 is provided with a square groove. The inside of the rotating disk 31 is provided with round holes, and the round holes are distributed in a ring. The push plate 35 is L-shaped. The inside of the conveying pipe 34 is provided with through holes.

[0049] In implementing this embodiment, external plastic storage bottles can be stacked and placed inside the delivery pipe 34. The bottom end of the delivery pipe 34 is aligned with the top end of the rotating disk 31. When the circular hole in the rotating disk 31 is not rotated to align with the through hole inside the delivery pipe 34, the rotating disk 31 can prevent the plastic storage bottles inside the delivery pipe 34 from falling downwards. Subsequently, other plastic storage bottles are placed into the circular hole inside the rotating disk 31 in sequence. When the multi-channel substrate filling arm 2 rotates away from the end of the waste liquid multi-channel substrate pipe connector 5, the transmission gear 21 can drive the first rack 22 and the second rack 12 to rotate synchronously. At this time, the first rack 22 will move to the right and connect to the connecting square rod 18 through the second connecting rod 20, so that the connecting square rod 18 can drive the alignment plate. The alignment plate 16 contacts the right-side limiting partition 30. Through the blocking action of the right-side limiting partition 30, the alignment plate 16 can move rearward, causing the rear end of the plastic disc 15 to adhere to the front surface of the plastic ring 32. Furthermore, it adheres to the iron plate 14 through the magnetic suction piece 13, preventing temporary displacement of the iron plate 14. Then, the motor 9 is turned on, driving the multi-channel substrate filling arm 2 to rotate towards the end near the waste liquid multi-channel substrate pipe connector 5. At this time, the first rack 22 can move in the reverse direction. At this time, through the plastic disc 15 adhering to the front surface of the plastic ring 32, the plastic disc 15 can drive the plastic ring 32 to rotate when it moves to the right. Furthermore, when the connecting square rod 18 is halfway through the displacement of the first rack 22, the right side of the alignment plate 16 can contact the right-side limiting partition 30. When the partition plate 30 contacts the connecting rod 18 and it continues to move to the right, the alignment plate 16 can move forward along the surface of the right-side limiting partition plate 30, allowing the iron plate 14 to disengage the plastic disc 15 from the plastic ring 32. At the same time, the rotating disc 31 can drive the circular hole to align perpendicularly with the multi-channel substrate dispensing arm 2, which has been rotated to the designated position. When the external pump is turned on, the substrate can be delivered into the plastic storage bottle inside the rotating disc 31, completing the task of receiving the substrate in the plastic storage bottle. Meanwhile, when the first rack 22 moves to the right, the second rack 12 can move to the left, allowing the third connecting rod 25 to drive the limiting rod 24 to press the first connecting rod 19 and the movable rod 38 back to their original positions. At this time, the push plate 35 can engage with the circular hole inside the rotating disc 31. The misalignment allows the plastic storage bottle containing the substrate to fall into the guide cavity 36 when the rotating disk 31 rotates again. The above steps can then be repeated. When the multi-channel substrate dispensing arm 2 rotates towards the end near the waste liquid multi-channel substrate connector 5, the transmission gear 21 drives the second rack 12 to move to the right. At this time, the third connecting rod 25 can drive the first connecting rod 19 and the movable rod 38 to move to the right via the limiting rod 24, allowing the push plate 35 to push the plastic storage bottle containing the substrate inside the guide cavity 36. Furthermore, the reset spring 26 allows the third connecting rod 25 to continue moving to the right, facilitating the full movement of the third connecting rod 25 and completing the single discharge of the plastic storage bottle from the guide cavity 36. When using this device…With the multi-channel substrate dispensing arm 2 initially aligned perpendicularly to the waste liquid multi-channel substrate connector 5, and the plastic disc 15 and plastic ring 32 in contact, the motor 9 drives the multi-channel substrate dispensing arm 2 to rotate away from the waste liquid multi-channel substrate connector 5. The plastic disc 15 passes over the surface of the plastic ring 32, causing the plastic storage bottle inside the rotating disk 31 to align with the multi-channel substrate dispensing arm 2 after a 90° rotation. Simultaneously, the second rack 12 can shift to the left, causing the third connecting rod 25 to drive the first connecting rod 19 and the movable rod 38 to shift to the right. This allows the push plate 35 to be misaligned with the circular hole inside the rotating disk 31, facilitating the movement of the previous plastic storage bottle containing substrate above the guide cavity 36 as the rotating disk 31 rotates. The plastic storage bottle then falls into the guide cavity 36. Subsequently, the multi-channel substrate dispensing arm 2 moves closer to the waste liquid multi-channel substrate connector. When one end of connector 5 rotates, the transmission gear 21 drives the first rack 22 to move to the left, and the second rack 12 to move to the right. When the first rack 22 moves to the left, it drives the second connecting rod 20 to reset. When the second connecting rod 20 resets, the plastic disc 15 will not pass over the surface of the plastic ring 32, thus preventing the plastic disc 15 from driving the rotating disc 31 to rotate again. Furthermore, when the connecting rod 18 resets, the plastic disc 15 can again contact the surface of the plastic ring 32. Simultaneously, when the second rack 12 moves to the right, the third connecting rod 25 drives the first connecting rod 19 and the movable rod 38 to move to the right, allowing the push plate 35 to push the plastic storage bottle located at the bottom of the guide cavity 36 to the right, completing the work of transferring a single plastic storage bottle. Moreover, the reset spring 26 allows the second rack 12 to continuously move the third connecting rod 25, completing the work.

10. The detection device of a chemiluminescence immunoassay analyzer according to claim 9, characterized in that: In use, this chemiluminescence immunoassay analyzer typically uses luminescent substances as markers attached to antigens or antibodies. When the antigen and antibody bind to form a complex, the luminescent substances also aggregate. Under specific conditions, these luminescent substances undergo a chemical reaction, releasing energy and generating a light signal. The intensity of the light signal is directly proportional to the concentration of the analyte. The concentration of the analyte is indirectly determined by measuring the intensity of the light signal. Based on the different chemiluminescent substances labeled on the antigens and antibodies and their corresponding excitation substrates, chemiluminescence is divided into two main types: direct luminescence and indirect luminescence. Direct luminescence generally uses chemical substances such as acridinium esters and luminol labeled on antigens and antibodies, requiring corresponding substrates for excitation. Indirect luminescence generally uses alkaline phosphatase or horseradish peroxidase labeled on antigens and antibodies, requiring their corresponding substrates for excitation. By using multiple substrate pipelines to deliver different chemiluminescent substrates, a single instrument can simultaneously detect both direct and indirect luminescence types.
