Description

Technical Field

[0001] This utility model belongs to the field of biochemical analyzer technology, specifically a pipetting detection device for a fully automated biochemical analyzer. Background Technology

[0002] A biochemical analyzer, also known as a biochemical instrument, is an instrument that uses photoelectric colorimetry to measure specific chemical components in body fluids. Due to its fast measurement speed, high accuracy, and low reagent consumption, it is now widely used in hospitals, epidemic prevention stations, and family planning service stations at all levels. The pipetting and detection device is one of the core components of a biochemical analyzer, responsible for accurately transferring and detecting liquid samples.

[0003] In existing technologies, the detection probes of biochemical analyzers are installed in relatively fixed positions. During detection, the test tube rack rotates, causing the test tubes to rotate and allowing multiple test tubes to be tested. However, when the test tube rack rotates too quickly or the liquid level in the test tubes is high, liquid can easily spill out during rotation, contaminating the analyzer. To address this, we provide a pipetting detection device for fully automated biochemical analyzers. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that liquid can easily spill out during rotation when the test tube rack rotates too fast or the liquid level in the test tube is too high, thus contaminating the analyzer, a pipetting detection device for a fully automated biochemical analyzer is proposed.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Specific implementation examples are given below.

[0039] Example 1:

[0040] Please see Figures 1 to 4 This utility model provides a pipetting detection device for a fully automated biochemical analyzer, comprising:

[0041] The base 1 and the fixing plate 2 fixedly installed on the upper end of the base 1, with a support plate 3 fixedly installed at the front end of the fixing plate 2;

[0042] Adjustment component 4 is installed at the front center of the fixed plate 2 and is used to adjust the detection position;

[0043] Detection component 5, installed at the rear end of adjustment component 4, is used to detect liquid;

[0044] Placement component 6 is installed on the upper end of support plate 3 and is used to place the liquid to be tested;

[0045] Locking component 7 is installed on the upper end of placement component 6 to improve stability during liquid detection.

[0046] In this embodiment, the liquid to be tested is placed in the placement component 6 to facilitate liquid testing. At the same time, the locking component 7 improves the stability of the liquid placement. Then, the adjustment component 4 is activated to drive the detection component 5 to slide and adjust the position of the detection component 5. Subsequently, the liquid is tested through the detection component 5, which facilitates the testing of multiple liquid tubes, improves the testing efficiency, reduces the shaking of the liquid to be tested, and avoids spillage that could contaminate the analyzer.

[0047] Example 2:

[0048] Based on Example 1, the adjustment component 4 and the detection component 5 are further disclosed.

[0049] like Figure 1 , Figure 3 and Figure 4As shown, the adjusting assembly 4 includes: a first rotating shaft 401 rotatably connected to the left and right sides of the fixed plate 2; a first gear 402 fixedly mounted on the outer side of the first rotating shaft 401; a first transmission belt 403 meshing with the outer side of the first gear 402; a first locking platform 404 meshing with the upper end of the first transmission belt 403; a second locking platform 405 fixedly mounted on the upper end of the first locking platform 404; a stabilizing platform 406 fixedly mounted at the rear end of the second locking platform 405; and the front end of the fixed plate 2 fixedly located above the second locking platform 405. The detection assembly 5, equipped with a slide bar 407, includes: a second rotating shaft 501 rotatably connected to the right side of the rear end of the stabilizer 406; a second gear 502 fixedly mounted on the outside of the second rotating shaft 501; a second transmission belt 503 meshing on the outside of the second gear 502; a slide table 504 meshing on the left side of the second transmission belt 503; an adjusting block 505 fixedly mounted on the left side of the slide table 504; a detection arm 506 fixedly mounted on the front side of the upper end of the adjusting block 505; and a detection needle 507 fixedly mounted on the lower end of the detection arm 506.

[0050] In this embodiment, after the liquid to be tested is placed into the placement component 6, the motor is started to drive the first rotating shaft 401 to rotate. The rotation of the first rotating shaft 401 drives the first gear 402 to rotate, thereby driving the meshing first transmission belt 403 to rotate, which in turn drives the first locking platform 404 to slide. The first locking platform 404 simultaneously drives the second locking platform 405 to slide, and the second locking platform 405 will slide synchronously on the slider 407 to ensure the stability of the second locking platform 405 during sliding. The stabilizing platform 406 will also slide synchronously with the second locking platform 405, thereby driving the detection component 5 to move to the test tube to be tested. The upper part of the instrument facilitates the testing of multiple liquid tubes while preventing liquid spillage and contamination of the analyzer due to test tube movement. The motor is then activated, driving the second rotating shaft 501 to rotate. The rotation of the second rotating shaft 501 drives the second gear 502, which in turn drives the meshing second transmission belt 503. The slide table 504 moves along with the second transmission belt 503, causing the adjusting block 505 to slide up and down. This allows the detection needle 507 on the detection arm 506 to be inserted into the test tube for liquid testing. This facilitates biochemical analysis and allows for adjustment of the insertion depth of the detection needle 507 into the test tube, preventing the deposition of elements inside the liquid from affecting the test results.

[0051] Example 3:

[0052] Based on Embodiment 1, the placement component 6 is further disclosed.

[0053] like Figure 1 and Figure 2As shown, the placement component 6 includes: a placement platform 601 fixedly installed on the upper end of the support plate 3, a detection platform 602 snapped onto the upper left side of the placement platform 601, a cleaning cylinder 603 snapped onto the upper right side of the placement platform 601, an installation groove 604 is provided inside the detection platform 602, and a test tube rack 605 is slidably connected inside the installation groove 604.

[0054] In this embodiment, the test tubes to be tested are placed in the test tube rack 605, and then the test tube rack 605 is inserted into the mounting slot 604 on the testing stage 602. The test tube rack 605 has placement openings of different diameters to facilitate the placement of test tubes of different sizes. After the detection needle 507 has completed the test, the detection needle 507 is moved and inserted into the cleaning cylinder 603. Clean water is circulated into the cleaning cylinder 603 to clean the detection needle 507, so as to avoid corrosion of the detection needle 507 by residual substances on the surface of the detection needle 507, and at the same time to avoid the residual substances of the detection needle 507 affecting subsequent tests.

[0055] Example 4:

[0056] Based on Embodiment 1, a locking component 7 is further disclosed.

[0057] like Figure 1 and Figure 2 As shown, the locking assembly 7 includes: a fixed post 701 attached to the upper left side of the testing table 602, a roller 702 rotatably connected to the outside of the fixed post 701, an adjusting nut 703 rotatably connected to the upper end of the fixed post 701, a spring 704 sleeved on the outside of the adjusting nut 703, and the lower end of the adjusting nut 703 threadedly connected to the testing table 602.

[0058] In this embodiment, when the test tube rack 605 is inserted into the mounting slot 604, the spring 704 pushes the fixing post 701 downward, so that the roller 702 on the fixing post 701 is in close contact with the upper end of the test tube rack 605. Then, the test tube rack 605 is pushed into the mounting slot 604, and the roller 702 presses the test tube rack 605 to ensure the stability of the test tube rack 605. At the same time, when installing test tube racks 605 of different heights, the adjusting nut 703 is rotated to drive the adjusting nut 703 to rise or fall, thereby adjusting the downward pressure on the test tube rack 605. This allows the tension of the spring 704 to be adjusted as needed to adapt to different test tube racks 605.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
