Description

Technical Field

[0001] The utility model relates to a reagent tray, in particular to a reagent tray for a chemiluminescence immunoassay analyzer. Background Technique

[0002] Chemiluminescence-labeled immunoassay, also known as chemiluminescence immunoassay, is an immunoassay method that directly labels antigens or antibodies with chemiluminescent agents. It can detect data such as hormones, tumor markers, and drugs in the human body, and plays a crucial role in the diagnosis and treatment of diseases, helping doctors diagnose and treat diseases. It can also be used in clinical fields such as drug concentration monitoring and immuno-disease diagnosis.

[0003] A chemiluminescence immunoassay analyzer mainly consists of a sample tray, a reagent tray, an incubator, a detector, a control system, and a data processing system. Among them, the sample tray is used to place the samples to be tested, the reagent tray places the required chemiluminescence reaction solution, the incubator is where the samples and reagents react at an appropriate temperature, and the detector is where the chemiluminescence signal is captured. It is mainly based on the specificity of the antigen-antibody reaction. The target antigen or antibody is combined with a chemiluminescent label to form an antigen-antibody-luminescence label complex. By detecting the light intensity emitted by the complex, the concentration of the target antigen or antibody can be deduced.

[0004] When using the sample tray and the reagent tray, it is necessary to place the test tube holder containing test tubes into the accommodating grooves of the sample tray or the reagent tray. The sizes of the accommodating grooves of the existing reagent trays and sample trays are fixed and can only accommodate test tube holders of one specification. At the same time, due to the tight fit between the test tube holder and the accommodating groove, it is relatively difficult to take out and put the test tube holder into the accommodating groove. Especially when there is reagent in the test tube, it is easy to shake, causing the reagent to splash out and resulting in waste. Content of the Utility Model

Specific embodiments

[0028] The following describes the present utility model in detail with reference to the accompanying drawings and embodiments:

[0029] The reagent tray for a chemiluminescence immunoassay detector according to the present utility model includes a reagent tray 2 rotatably connected in a workbench 1. The upper end surface of the reagent tray 2 is provided with a plurality of receiving grooves 3 in the vertical direction. Each receiving groove 3 is uniformly arranged along the circumference on the upper end surface of the reagent tray 2. Two clamping plates 5 are slidably arranged in each receiving groove 3 along the length direction of the receiving groove 3. The lower end surfaces of the two clamping plates 5 are fixedly provided with sliding rods 6. The sliding rods 6 are located in sliding grooves 7 opened on the inner bottom wall of the receiving groove 3 along the length direction of the receiving groove 3. The sliding rods 6 are slidably arranged with the reagent tray 2 through the sliding grooves 7. A plurality of ejecting devices are arranged in the reagent tray 2. The ejecting devices are all connected to the corresponding two sliding rods 6. The ejecting devices are used to drive the corresponding two sliding rods 6 to move away from each other and upward to eject the test tube receiving body 4.

[0030] During use, first place the test tube receiving body 4 into the receiving groove 3 of the reagent tray 2, and then drive the corresponding two sliding rods 6 to move closer to each other through the ejecting device, thereby driving the clamping plates 5 to move closer to each other to clamp the test tube receiving body 4, achieving the purpose of fixing the test tube receiving body 4. The clamping of the test tube receiving body 4 by the clamping plates 5 can adapt to test tube receiving bodies 4 of various length specifications. When it is necessary to take out the test tube receiving body 4, drive the corresponding two sliding rods 6 to move away from each other through the ejecting device, thereby driving the two clamping plates 5 to move away from each other. At the same time, the ejecting device ejects the test tube receiving body 4 to a set height, facilitating the taking out of the test tube receiving body 4.

[0031] In order to achieve the purpose that when the two clamping plates 5 release the test tube accommodating body 4, the test tube accommodating body 4 is pushed upward by a set height. In this embodiment, a movable groove 8 is formed on the inner bottom wall of the sliding groove 7. The ejecting device includes a driving block 9 slidably arranged in the movable groove 8 in the up and down direction. Both side surfaces of the driving block 9 are hinged with a connecting rod 10, and the outer end of each connecting rod 10 is hinged with the corresponding sliding rod 6. During use, when the driving block 9 moves downward, it drives the two sliding rods 6 to move closer to each other in the sliding groove 7 through the two connecting rods 10, and then drives the corresponding two clamping plates 5 to move closer to each other to clamp the test tube accommodating body 4. When the driving block 9 moves downward, the upper end surface of the driving block 9 moves below the inner bottom wall of the accommodating groove 3, which does not prevent the test tube accommodating body 4 from being placed downward into the accommodating groove 3. When it is necessary to take out the test tube accommodating body 4, the driving block 9 is moved upward, so that the driving block 9 drives the corresponding two clamping plates 5 to move away from each other through the two connecting rods 10, releasing the test tube accommodating body 4. At the same time, when the driving block 9 moves upward, the upper end surface of the driving block 9 protrudes from the inner bottom wall of the accommodating groove 3 to push the test tube accommodating body 4 upward by a set height, facilitating the taking out of the test tube accommodating body 4.

[0032] When the length of the test tube accommodating body 4 is relatively long, the two driving blocks 9 move downward to drive the two clamping plates 5 to move closer to each other through the connecting rods 10 to clamp the test tube accommodating body 4. Due to the relatively long length of the test tube accommodating body 4, before the upper end surface of the driving block 9 moves below the inner bottom wall of the accommodating groove 3, the two clamping plates 5 have already clamped the test tube accommodating body 4, resulting in the upper end surface of the driving block 9 interfering with the downward placement of the test tube accommodating body 4 into the accommodating groove 3.

[0033] In order to solve the above technical problems and increase the applicable range of the two clamping plates 5, in this embodiment, springs 11 are fixedly arranged on one side surface of the two clamping plates 5 close to each other, and sliding plates 12 are fixedly arranged at the ends of the springs 11 close to each other. During use, when the driving block 9 moves downward, it drives the corresponding two sliding rods 6 to move closer to each other through the two connecting rods 10, and then drives the corresponding two clamping plates 5 to move closer to each other. The two sliding plates 12 first come into contact with the two side surfaces of the test tube accommodating body 4 to achieve preliminary clamping. As the driving block 9 continues to move downward, the two clamping plates 5 continue to move closer to each other to compress the springs 11 until the upper end surface of the driving block 9 moves below the inner bottom wall of the accommodating groove 3, realizing the clamping and fixing of the test tube accommodating body 4. By arranging the sliding plates 12 and the springs 11, the length of the accommodating groove 3 can be designed to be longer to adapt to the clamping of the test tube accommodating body 4 with a longer length, increasing the applicable range of the two clamping plates 5.

[0034] In order to achieve the purpose of driving each driving block 9 to move upward or downward synchronously, in this embodiment, a connecting body 13 is rotatably connected to the lower end surface of the reagent tray 2. A toothed ring 14 is fixedly arranged on the lower end surface of the connecting body 13. A plurality of internal teeth are uniformly and fixedly arranged on the inner side wall of the toothed ring 14, and a plurality of external teeth are uniformly and fixedly arranged on the outer side wall of the toothed ring 14. A threaded rod 15 is fixedly arranged on the lower end surface of each driving block 9 in the vertical direction. A first gear 16 is threadedly connected to the outer surface of each threaded rod 15. Each first gear 16 meshes with the toothed ring 14 through the internal teeth of the toothed ring 14; a plurality of L-shaped plates 17 are uniformly and fixedly arranged on the outer edge of the lower end surface of the reagent tray 2 in the circumferential direction. The horizontal part of each L-shaped plate 17 is located below the toothed ring 14. Each threaded rod 15 is slidably arranged in the horizontal part of the corresponding L-shaped plate 17 in the vertical direction. Each first gear 16 is rotatably connected to the horizontal part of the corresponding L-shaped plate 17; by rotating the toothed ring 14, each first gear 16 is driven to rotate self, and each first gear 16 rotates self to drive each threaded rod 15 to move up and down in the horizontal part of the L-shaped plate 17, thereby driving each driving block 9 to move upward or downward synchronously.

[0035] In order to achieve the purpose of driving the toothed ring 14 to rotate, in this embodiment, a servo motor 18 is fixedly arranged on the lower end surface of the horizontal part of one of the L-shaped plates. The output shaft of the servo motor 18 protrudes upward from the upper end surface of the L-shaped plate 17 and is fixedly provided with a second gear 19. The second gear 19 meshes with the toothed ring 14 through the external teeth of the toothed ring 14; when it is necessary to take out the test tube accommodating body 4, the servo motor 18 drives the second gear 19, the toothed ring 14, the first gear 16 and the threaded rod 15 in sequence to drive the driving block 9 to move upward, so that the driving block 9 drives every two corresponding clamping plates 5 to move away through the connecting rod 10 and the sliding rod 6, thereby driving the sliding plate 12 to disengage from the clamping of the test tube accommodating body 4. At the same time, the driving block 9 moving upward also pushes the test tube accommodating body 4 upward by a set height, facilitating the taking out of the test tube accommodating body 4; when fixing the test tube accommodating body 4, the test tube accommodating body 4 is placed in the accommodating groove 3 of the reagent tray 2, and then the servo motor 18 is started to drive each driving block 9 to move downward, thereby driving the clamping plate 5 to clamp the test tube accommodating body 4. At the same time, the driving block 9 moves downward below the inner bottom wall of the accommodating groove 3, so that the lower end surface of the test tube accommodating body 4 contacts the inner bottom wall of the accommodating groove 3; the installation and fixation of the test tube accommodating body 4 are completed.

[0036] In order to achieve the purpose of driving the reagent tray 2 to rotate relative to the workbench 1, in this embodiment, a vertical shaft 21 is coaxially and fixedly arranged inside the reagent tray 2. The bottom end of the vertical shaft 21 is rotatably connected with a bearing 22. A plurality of support frames 23 are uniformly and fixedly arranged on the outer surface of the bearing 22 in the circumferential direction. The top end of each support frame 23 is fixedly arranged with the lower end surface of the workbench 1; the rotation of the vertical shaft 21 drives the rotation of the reagent tray 2.

[0037] In this embodiment, a driving motor 24 is arranged below the workbench 1. The output shaft of the driving motor 24 is fixedly arranged with the bottom end of the vertical shaft 21, and the outer surface of the driving motor 24 is fixedly arranged with each support frame 23. The driving motor 24 drives the reagent tray 2 to rotate through the vertical shaft 21.

[0038] In order to achieve the purpose of sampling the reagent in the test tube in the test tube holder 4, in this embodiment, a sampling needle 20 is arranged on the upper end surface of the workbench 1. During operation, the sampling needle 20 can rotate and move up and down, and can achieve the purpose of extracting the reagent from the test tube.

[0039] In this embodiment, a sealing cover 25 is arranged on the upper end surface of the workbench 1, and a computer 26 is arranged on one side of the workbench 1. During use, after the test tube holder 4 is fixedly installed in the reagent tray 2, the sealing cover 25 is closed, and the sampling needle 20 is started through the control of the computer 26 to work, extracting the reagent to be tested or the chemiluminescent reaction solution from the test tube, putting it into the incubator for reaction, and then the detector captures the intensity of the chemiluminescent signal to calculate the concentration of the target antigen or antibody. The computer 26 controls the entire analysis process through the control system.

[0040] Working principle: When the test tube holder 4 needs to be placed in the reagent tray 2, first, each test tube holder 4 is placed in the placement groove 3 of the reagent tray 2. Then, the servo motor 18 drives the second gear 19, the toothed ring 14, the first gear 16, and the threaded rod 15 in sequence to drive the driving block 9 to move downward, so that the driving block 9 drives the corresponding two clamping plates 5 to move closer through the connecting rod 10 and the slide rod 6, thereby driving the slide plate 12 to clamp the test tube holder 4. At the same time, the driving block 9 moves downward below the inner bottom wall of the placement groove 3, so that the lower end surface of the test tube holder 4 contacts the inner bottom wall of the placement groove 3, completing the fixed installation of the test tube holder 4; during operation, the sampling needle 20 can rotate and move up and down, and can achieve the purpose of extracting the reagent to be tested or the optical luminescence reaction solution from the test tube; when the test tube holder 4 needs to be taken out, the servo motor 18 drives the second gear 19, the toothed ring 14, the first gear 16, and the threaded rod 15 in sequence to drive the driving block 9 to move upward, so that the driving block 9 drives the corresponding two clamping plates 5 to move away through the connecting rod 10 and the slide rod 6, thereby driving the slide plate 12 to disengage from the clamping of the test tube holder 4. At the same time, the upward movement of the driving block 9 also pushes the test tube holder 4 upward to a set height, facilitating the removal of the test tube holder 4; when the device is working normally, the reagent tray 2 rotates intermittently driven by the driving motor 24. When the reagent tray 2 rotates, the servo motor 18, the L-shaped plate 17, the second gear 19, the toothed ring 14, the first gear 16, and the threaded rod 15 rotate synchronously, which is a revolution and will not cause the threaded rod 15 to move up and down. Only when the servo motor 18 starts, the threaded rod 15 rotates, and the threaded rod 15 will move up and down. The servo motor 18 has a self-locking function when it stops, keeping the second gear 19 stationary. Since the second gear 19 meshes with the toothed ring 14, the toothed ring 14 also remains stationary. The toothed ring 14 meshes with the first gear 16, and the first gear 16 also remains stationary. Therefore, when the reagent tray 2 rotates, the threaded rod 15 will not move up and down.
