Description

Technical Field

[0001] The utility model relates to the technical field of reaction cup displacement, in particular to a reaction cup displacement device for an immunoassay analyzer. Background Art

[0002] At present, in vitro diagnosis is one of the most commonly used diagnostic methods in the medical field. According to the detection principle or detection method, in vitro diagnosis is mainly divided into biochemical diagnosis, immunological diagnosis, molecular diagnosis, microbiological diagnosis, urine diagnosis, coagulation diagnosis, blood and flow cytometric diagnosis, etc. Among them, biochemical and immunological are the main methods of in vitro diagnosis in my country. These diagnostic methods all use fully automatic or semi-automatic instruments to add samples, analyze and give diagnostic reports.

[0003] During the test, a reaction cup is needed to hold the reaction reagent and body fluid sample and mix them. After a period of reaction in a heated and heat-insulating environment, the reaction cup is transported to the detection position for photoelectric conversion detection.

[0004] Immunoassay analyzers often use disposable cuvettes. As test consumables, cuvettes need to be replenished and removed (loaded and unloaded). Usually, cuvettes are placed in cuvette receiving grooves distributed along the circumference of the reaction disk. Due to the ratio of the diameter of the cuvette and the reaction disk, the number of cuvettes that can be accommodated in a single row of reaction disks is limited. To increase the number of cuvettes, the diameter of the reaction disk must also be made larger, which is not conducive to the miniaturization of the equipment.

[0005] In addition, a robot or other mechanism is required to automatically load and unload the reaction cup, so it is necessary to design a reaction cup displacement device with a compact structure, fast action and low cost to realize automatic loading and unloading of the reaction cup.

[0006] Furthermore, high-speed immunoassay analyzers require an efficient testing rhythm, but the reaction disk has large inertia, and each start and stop will affect the test speed. The reaction cup loading position and discard position of common equipment are arranged separately, which not only makes the mechanism repetitive and complicated, increasing the size and cost of the equipment, but also reduces operating efficiency. Utility Model Content

[0007] The utility model provides a reaction cup displacement device for an immunoassay analyzer, which solves the above-mentioned technical problems.

[0008] The utility model solves the above-mentioned technical problems as follows:

[0009] A reaction cup displacement device for an immunoassay analyzer comprises a reaction cup, a tray, a base and a reaction disk, wherein a discarding catheter is arranged inside the reaction disk, a tray is rotatably mounted inside the reaction disk, a reaction cup is supported on the tray, a base is mounted on one side of the reaction disk, a stepping motor is mounted on one side of the base, a driving gear is mounted on the output end of the stepping motor, a rack is mounted on the base through the meshing of the driving gear, a push-pull electromagnet is mounted on one end of the rack facing the reaction disk, a slope is arranged on one side of the base, and the slope is used to store the reaction cup.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the rack is slidably mounted on the base via a guide rail and a slider.

[0012] The beneficial effects of adopting the above further scheme are:

[0013] Smooth movement: The design of the guide rails and sliders ensures that the rack slides smoothly on the base, thus ensuring the stability and smoothness of the reaction cup during the movement inside the device. This helps to avoid the situation where the reaction cup is not positioned correctly or moves smoothly due to friction or unstable movement.

[0014] Accurate positioning: Through the design of the guide rail and the slider, the movement trajectory of the rack can be accurately controlled, thereby ensuring the accurate positioning of the reaction cup inside the device. This is especially important for experiments that require precise control of the reaction process, because the accurate position of the reaction cup directly affects the accuracy of the experimental results.

This is especially important for experiments that run for a long time or are used frequently, because a stable device can ensure the continuity and consistency of the experiment.

[0016] Easy to maintain and adjust: The structure of the guide rail and slider is relatively simple, easy to maintain and adjust. If the device needs to be maintained or adjusted, the operator can easily adjust the position of the guide rail and slider or replace the damaged parts without complicated operations or disassembly of the device.

[0017] Furthermore, a chopper is installed on the rack, an electro-optical switch is provided on the base, and the moving distance of the rack is limited by the electro-optical switch and the chopper.

[0018] The beneficial effects of adopting the above further scheme are:

[0019] Precise control of the moving range: The combination of the electro-optical switch and the chopper can achieve precise control of the rack moving distance. The electro-optical switch can sense the position of the chopper to determine the current position of the rack, and control the rack to stop or move according to the preset parameters to ensure that the reaction cup stays at a specific position or moves to a specified position.

[0020] Preventing out-of-range: The electro-optical switch and chopper can effectively prevent the rack from exceeding the set range during movement. Once the electro-optical switch detects that the position of the chopper reaches the preset limit point, it will send a signal to stop the movement of the rack, thus avoiding damage or errors caused by the device exceeding the design range.

[0021] Improve safety: Limiting the range of movement of the rack can reduce the occurrence of unexpected situations and improve the safety of the device. Especially in automated operations, ensuring that the movement of the reaction cup is within a safe range can reduce the risk to operators and equipment and ensure the safety of the laboratory.

[0022] Ensure experimental accuracy: Precisely controlling the range of movement and preventing it from exceeding the range can ensure the accuracy and repeatability of the experiment. In experiments that require precise control of reaction conditions, it is very important to ensure that the reaction cup stays in the correct position or moves to the specified position, so as to avoid errors in experimental results caused by inappropriate reaction conditions.

[0023] Furthermore, the tray is provided with a guide groove, and the reaction cup enters the tray through the guide groove.

[0024] The beneficial effects of adopting the above further scheme are:

[0025] Accurate positioning: The guide groove can ensure that the reaction cup has an accurate position and direction when entering the tray. This can avoid the loading failure or poor movement of the reaction cup due to inaccurate position, ensuring the smooth progress of the experiment.

[0026] Prevent collision and damage: The guide groove can effectively guide the reaction cup into the tray, avoiding collision or friction between the reaction cups or other parts of the device, thereby reducing the risk of damage to the reaction cup and the device.

[0027] Improve loading efficiency: Through the design of the guide groove, operators can load the reaction cup onto the tray more easily without spending too much time and energy to adjust the position of the reaction cup, thereby improving loading efficiency.

[0028] Increased stability: The guide grooves can increase the stability of the reaction cup on the tray, ensuring that the reaction cup remains stable during the movement inside the device. This is especially important for experiments that require long-term operation or high-frequency use, which can ensure the continuity and consistency of the experimental process.

[0029] Reduce misoperation: Through the guidance of the guide groove, the operator can reduce the possibility of incorrect or failed cuvette loading due to misoperation, thereby improving the accuracy and reliability of the experiment.

[0030] Furthermore, the discarding conduit is located on a side of the reaction disk close to the rack.

[0031] The beneficial effects of adopting the above further scheme are:

[0032] Simplified discharge process: Placing the discard tube on the side close to the rack can simplify the discharge process of the reaction cup. Because the rack is usually responsible for driving the reaction cup to the next stage or position, placing the discard tube near the rack can directly discharge the reaction cup from the rack, eliminating additional movement steps and complex pipe design, and improving discharge efficiency.

[0033] Space saving: Placing the discard tube on the side close to the rack can effectively utilize the space inside the device. This design can avoid taking up too much space in other positions of the reaction disk to place the discard tube, making the overall structure of the device more compact, which is conducive to conducting more experiments in a limited space.

[0034] Convenient operation: The discard tube is located near the rack, so the operator can more conveniently discharge the reaction cup to the designated location. This design can reduce the operator's operating steps and actions, simplify the operation process, and improve the convenience and efficiency of the operation.

[0035] Increased stability: Placing the discard tube close to the rack can increase the stability of the device. Because the position of the reaction cup is closely related to the rack during the discharge process, this design can ensure the stability of the discharge process and reduce the risk of misoperation or damage caused by unstable discharge process.

[0036] Reduce the complexity of the device structure: Placing the discarding catheter on the side close to the rack can simplify the structural design of the device. This design can reduce additional pipeline connections and device components, reduce the manufacturing cost of the device, and improve the reliability and practicality of the device.

[0037] Furthermore, there are two push-pull electromagnets in total, and the reaction cups on the slope are sent to the tray through the push-pull electromagnets.

[0038] The beneficial effects of adopting the above further scheme are:

[0039] Double protection: The use of two push-pull electromagnets can provide double protection, increasing the stability and reliability of cuvette loading. Even if one of the push-pull electromagnets fails, the other can still continue to work, ensuring the smooth loading of the cuvette and reducing interruptions and failures during the loading process.

[0040] Increase loading efficiency: Using two push-pull electromagnets can speed up the loading of the reaction cup. The two electromagnets can work at the same time to quickly and efficiently send the reaction cup to the tray, which improves the loading efficiency and reduces the time required for the loading process.

[0041] Reduce the instability of the reaction cup movement: Two push-pull electromagnets are used to send the reaction cup to the tray, which can more stably control the movement of the reaction cup. The two electromagnets work together to ensure that the reaction cup maintains a smooth movement trajectory during the loading process, reducing the shaking and instability during the loading process, which is conducive to the stable operation of the device.

[0042] Enhanced reliability of the device: The design of the dual push-pull electromagnet enhances the reliability and robustness of the device. The two electromagnets can work together to ensure the stability and reliability of the device during long-term operation or high-frequency use, and reduce the risk of downtime caused by single-point failure.

[0043] Operational flexibility: The use of two push-pull electromagnets can increase the operational flexibility of the device. The operator can choose a single electromagnet or use two electromagnets at the same time for loading according to needs to adapt to different experimental requirements and the loading conditions of the reaction cup, which improves the applicability and flexibility of the device.

[0044] Furthermore, a limiting pin is provided at the end of the rack.

[0045] The beneficial effects of adopting the above further scheme are:

[0046] Precisely control the position: The limit pin can ensure that the rack stops at the predetermined position during the movement. By setting the limit pin, the movement distance and position of the reaction cup can be accurately controlled to ensure that the reaction cup accurately enters the specified position or stays at a specific position, which helps to ensure the accuracy and repeatability of the experiment.

[0047] Prevent excessive movement: The limit pin can prevent the rack from excessive movement during the movement process, which may cause unnecessary damage or failure. Once the rack reaches the predetermined position, the limit pin will limit its further movement, avoiding the adverse effects that excessive movement may bring, such as damage to the device structure or errors in experimental results.

[0048] Improve safety: The setting of the limit pin can improve the safety of the device. It can ensure that the reaction cup moves within the safe range, avoid the potential safety hazards caused by the reaction cup moving beyond the design range, and ensure the safety of operators and equipment.

[0049] Enhanced stability: The stability of the device can be enhanced by setting the limit pin. The limit pin can ensure that the reaction cup maintains a stable position during the movement inside the device, reducing the shaking and instability during the operation of the device, which is conducive to the smooth progress of the experiment and the accuracy of the results.

[0050] Extend the life of the device: The limit pin can effectively protect the key components of the device and extend the service life of the device. It can avoid damage or wear of device components caused by excessive movement or incorrect operation, reduce the maintenance cost and repair frequency of the device, and improve the reliability and durability of the device.

[0051] The beneficial effects of the utility model are:

[0052] High degree of automation: The device realizes automatic processing of reaction cups through mechanical structures such as motors and gear rack transmission, and can complete the recovery and loading of reaction cups without human intervention. This highly automated design greatly improves laboratory work efficiency, saves human resources, and reduces human errors during operation, which is conducive to improving the accuracy and repeatability of experimental data.

[0053] High space utilization: The tray is designed with guide grooves and recovery holes, which can effectively accommodate multiple reaction cups, and the multi-ring storage design makes full use of the space inside the device, improving the storage density of the reaction cups. This is especially important for laboratories, because laboratories usually have limited space. Being able to accommodate more reaction cups in a limited space can increase the scale and output of the experiment.

[0054] Precise control: The device precisely controls the movement of the reaction cup through components such as electro-optical switches, choppers and electromagnets. The electro-optical switches and choppers can ensure the accurate position of the reaction cup during movement, and the electromagnets can accurately control the insertion and ejection of the reaction cup, making the entire device highly stable and controllable during operation, which helps the smooth progress of the experiment and the accurate recording of data.

[0055] Strong stability: The device is designed with limit pins and other structures, which can effectively prevent the device from accidentally detaching or becoming unstable during use, ensuring the safety and stability of the experimental process.

[0073] Embodiment 1

[0074] A reaction cup displacement device for an immunoassay analyzer comprises a reaction cup 1, a tray 2, a base 12 and a reaction disk 13. A discarding conduit 14 is arranged inside the reaction disk 13. The discarding conduit 14 is located on a side of the reaction disk 13 close to a rack 7. Placing the discarding conduit 14 on a side close to the rack 7 can simplify the discharge process of the reaction cup 1. Because the rack 7 is usually responsible for driving the reaction cup 1 to enter the next stage or position, the discarding conduit 14 is placed near the rack 7, and the reaction cup 1 can be directly discharged from the rack 7, eliminating additional moving steps and complex pipeline design, and improving the discharge efficiency. Placing the discarding conduit 14 on a side close to the rack 7 can effectively utilize the space inside the device. This design can avoid taking up too much space at other positions of the reaction disk 13 to place the discarding conduit 14, making the overall structure of the device more compact, which is conducive to conducting more experiments in a limited space. The discarding conduit 14 is located near the rack 7, and the operator can more conveniently discharge the reaction cup 1 to the designated position. This design can reduce the operating steps and actions of the operator, simplify the operating process, and improve the convenience and efficiency of the operation. Placing the discarding conduit 14 on the side close to the rack 7 can increase the stability of the device. Because the position of the reaction cup 1 is closely related to the rack 7 during the discharge process, such a design can ensure the stability of the discharge process and reduce the risk of misoperation or damage caused by the instability of the discharge process. Placing the discarding conduit 14 on the side close to the rack 7 can simplify the structural design of the device. Such a design can reduce additional pipeline connections and device components, reduce the manufacturing cost of the device, and improve the reliability and practicality of the device. The tray 2 is rotatably installed inside the reaction disk 13, and the tray 2 is supported by the reaction cup 1. The tray 2 is provided with a guide groove, and the end of the guide groove is provided with a recovery hole. The position of the recovery hole corresponds to the position of the discarding conduit 14. While loading the reaction cup 1, the old reaction cup 1 is pushed into the recovery hole position, and then falls into the discarding conduit 14 for recovery. The reaction cup 1 enters the tray 2 through the guide groove. The tray 2 can accommodate multiple reaction cups 1 to achieve multi-ring storage of the reaction cup 1. The guide groove can ensure that the reaction cup 1 has an accurate position and direction when entering the tray 2. This can avoid the situation where the reaction cup 1 fails to load or moves smoothly due to inaccurate position, ensuring the smooth progress of the experiment. The guide groove can effectively guide the reaction cup 1 into the tray 2, avoiding collision or friction between the reaction cups 1 or other parts of the device, thereby reducing the risk of damage to the reaction cup 1 and the device. Through the design of the guide groove, the operator can load the reaction cup 1 onto the tray 2 more easily, without spending too much time and energy to adjust the position of the reaction cup 1, thereby improving the loading efficiency. The guide groove can increase the stability of the reaction cup 1 on the tray 2, ensuring that the reaction cup 1 remains stable during the movement inside the device. This is especially important for experiments that require long-term operation or high-frequency use, which can ensure the continuity and consistency of the experimental process.Through the guidance of the guide groove, the situation of incorrect loading or loading failure of the reaction cup 1 due to operator misoperation can be reduced, thereby improving the accuracy and reliability of the experiment.

[0075] A base 12 is installed on one side of the reaction disk 13, a stepper motor 10 is installed on one side of the base 12, a driving gear 5 is installed on the output end of the stepper motor 10, a rack 7 is installed on the base 12 through the meshing of the driving gear 5, and a low-cost gear rack transmission device is used to push the reaction cup 1 to move quickly along the radial direction of the reaction disk 13. The rack 7 is slidably installed on the base 12 through the guide rail 6 and the slider. The design of the guide rail and the slider can ensure that the rack 7 slides smoothly on the base 12, thereby ensuring the stability and smoothness of the reaction cup 1 during the movement inside the device. This helps to avoid the situation where the reaction cup 1 is inaccurately positioned or moves poorly due to friction or unstable movement. Through the design of the guide rail and the slider, the moving trajectory of the rack 7 can be accurately controlled, thereby ensuring the accurate positioning of the reaction cup 1 inside the device. This is particularly important for experiments that require accurate control of the reaction process, because the accurate position of the reaction cup 1 directly affects the accuracy of the experimental results. The guide rail and the slider provide additional support and stability, which can prevent the rack 7 from shaking or falling off during the movement, thereby increasing the reliability and stability of the device. This is particularly important for experiments that run for a long time or are used frequently, because a stable device can ensure the continuity and consistency of the experiment. The structure of the guide rail and the slider is relatively simple and easy to maintain and adjust. If the device needs to be maintained or adjusted, the operator can easily adjust the position of the guide rail and the slider or replace damaged parts without complicated operations or disassembly of the device. A chopper 11 is installed on the rack 7, and an electro-optical switch 9 is provided on the base 12. The rack 7 limits the moving distance by the electro-optical switch 9 and the chopper 11. Through the combination of the electro-optical switch 9 and the chopper 11, the moving distance of the rack 7 can be accurately controlled. The electro-optical switch 9 can sense the position of the chopper 11, thereby determining the current position of the rack 7, and control the stop or movement of the rack 7 according to the preset parameters, ensuring that the reaction cup 1 stays at a specific position or moves to a specified position. The electro-optical switch 9 and the chopper 11 can effectively prevent the rack 7 from exceeding the set range during the movement process. Once the electro-optical switch 9 detects that the position of the chopper 11 reaches the preset limit point, it will send a signal to stop the movement of the rack 7, thereby avoiding damage or errors caused by the device exceeding the design range. Limiting the movement range of the rack 7 can reduce the occurrence of unexpected situations and improve the safety of the device. Especially in automated operations, ensuring that the movement of the reaction cup 1 is within a safe range can reduce the risks to operators and equipment and ensure the safety of the laboratory. Accurately controlling the movement range and preventing it from exceeding the range can ensure the accuracy and repeatability of the experiment.In experiments that require precise control of reaction conditions, it is very important to ensure that the reaction cup 1 stays at the correct position or moves to the specified position, so as to avoid errors in experimental results caused by inappropriate reaction conditions. A push-pull electromagnet 3 is installed at one end of the rack 7 facing the reaction tray 13. There are two push-pull electromagnets 3. The rack 7 is driven by the active gear 6 to move, and the reaction cup 1 on the base 12 is pushed forward by one cup position, and the reaction cup 1 on the slope 4 supplements the empty position. After that, the push-pull electromagnet 3 extends and inserts the cup mouth of the reaction cup 1, and the active gear 5 drives the rack 7 to extend, thereby pushing the two reaction cups 1 into the guide groove. The reaction cup 1 on the slope 4 is sent to the tray 2 by the push-pull electromagnet 3. The use of two push-pull electromagnets 3 can provide double protection, which increases the stability and reliability of the loading of the reaction cup 1. Even if one of the push-pull electromagnets 3 fails, the other can still continue to work, ensuring the smooth loading of the reaction cup 1 and reducing interruptions and failures during the loading process. Using two push-pull electromagnets 3 can speed up the loading speed of the reaction cup 1. The two electromagnets can work at the same time to quickly and efficiently send the reaction cup 1 to the tray 2, thereby improving the efficiency of loading and reducing the time required for the loading process. The two push-pull electromagnets 3 are used to send the reaction cup 1 to the tray 2, so that the movement of the reaction cup 1 can be controlled more stably. The two electromagnets work together to ensure that the reaction cup 1 maintains a smooth moving trajectory during the loading process, reducing the shaking and instability during the loading process, which is conducive to the stable operation of the device. The design of the double push-pull electromagnet 3 enhances the reliability and robustness of the device. The two electromagnets can cooperate with each other to ensure the stability and reliability of the device during long-term operation or high-frequency use, and reduce the risk of downtime caused by single-point failure of the device. The use of two push-pull electromagnets 3 can increase the operational flexibility of the device. The operator can choose a single electromagnet or use two electromagnets at the same time for loading as needed to adapt to different experimental requirements and the loading conditions of the reaction cup 1, thereby improving the applicability and flexibility of the device. A limit pin 8 is provided at the end of the rack 7 to prevent the guide rail 6 from detaching from the slider during assembly. The limit pin 8 can ensure that the rack 7 stops at a predetermined position during movement. By setting the limit pin 8, the moving distance and position of the reaction cup 1 can be accurately controlled to ensure that the reaction cup 1 accurately enters the specified position or stays at a specific position, which helps to ensure the accuracy and repeatability of the experiment. The limit pin 8 can prevent the rack 7 from excessively moving during the movement process and causing unnecessary damage or failure. Once the rack 7 reaches the predetermined position, the limit pin 8 will limit its further movement, avoiding the adverse effects that may be caused by excessive movement, such as damage to the device structure or errors in the experimental results. The setting of the limit pin 8 can improve the safety of the device. It can ensure that the reaction cup 1 moves within a safe range, avoid safety hazards that may be caused by the movement of the reaction cup 1 beyond the design range, and ensure the safety of operators and equipment.The stability of the device can be enhanced by setting the limit pin 8. The limit pin 8 can ensure that the reaction cup 1 maintains a stable position during the movement inside the device, reducing the shaking and instability during the operation of the device, which is conducive to the smooth progress of the experiment and the accuracy of the results.
