Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological experimental device technology, and in particular to a sample labeling mechanism for a biological analysis plate. Background Technology
[0002] Bioanalytical well plates, also known as microplates, are experimental instruments commonly used in biological, chemical, and pharmaceutical research. They consist of multiple wells (holes), each of which can be used to place reagents, samples, or reactants, facilitating high-throughput, multi-sample experiments. Bioanalytical well plates are usually made of polypropylene, but special materials are also available to suit different detection methods. However, most existing bioanalytical well plates still have problems that need to be solved.
[0003] Most existing bioanalytical well plates lack a mechanism for identifying and recording reagent information during sample loading. This can easily lead to confusion between samples or reagents in different wells, resulting in misplacement or mix-up of samples and affecting the accuracy of experimental results. In subsequent data analysis or validation, the lack of identification makes it difficult to trace the history of a particular sample, thereby affecting the traceability and verifiability of the entire experiment. Therefore, it is necessary to design a sample loading identification mechanism for bioanalytical well plates to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sample labeling mechanism for bioanalytical well plates.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sample labeling mechanism for a bioanalytical well plate includes a bioanalytical well plate with a plurality of sample wells. Side plates are fixedly connected to the top of both ends of the bioanalytical well plate. A sliding groove is formed on the top of each side plate on its adjacent side. A slider is disposed within the groove and is adapted to fit the groove. The slider is slidably connected to the side plate. A common movable plate is fixedly connected to the two sliders on their adjacent sides. The movable plate has a plurality of circular holes, the distance between which is the same as the distance between the sample wells on the bioanalytical well plate. A plurality of L-shaped fixing shafts are fixedly connected to one side of the movable plate, and the L-shaped fixing shafts are disposed on one side of the circular holes. A rotating shaft is rotatably connected to the L-shaped fixing shaft, and a label cap is fixedly connected to one side of the rotating shaft. By setting the label cap, a label with sample reagent information can be affixed to the top of the label cap for labeling and recording. Samples are added through the circular orifice to the sample well. The position of the movable plate can be adjusted to position the circular orifice and label cap so that they are positioned at the top of the sample well. A label with reagent information is affixed to the top of the label cap, making the reagent and sample information of each well clear at a glance, reducing human error, and ensuring the accuracy of experimental data. This effectively solves the problem mentioned in the background art that most existing bioanalytical well plates lack a mechanism for identifying and recording reagent information, which easily leads to confusion of samples or reagents in different wells, resulting in sample misplacement or confusion and affecting the accuracy of experimental results. In subsequent data analysis or verification, the lack of identification makes it difficult to trace the history of a sample, thus affecting the traceability and verifiability of the entire experiment. Therefore, this technology effectively enhances the visibility and accuracy of identification. Complete identification records ensure that each experimental step is traceable, which helps with subsequent analysis and verification and enhances the reliability of experimental data.
[0007] As a further embodiment of this utility model, a lever is fixedly connected to the top of the label cover at the end away from the rotating shaft.
[0008] As a further embodiment of this utility model, a baffle is fixedly connected to the top of the L-shaped fixed shaft on the side away from the moving plate, and the baffle is inclined.
[0009] As a further embodiment of this utility model, two L-shaped plates are fixedly connected to the top of both ends of the movable plate. A round rod is passed through the L-shaped plate, and a pin is fixedly connected to the bottom of the round rod. A ring is fixedly connected to the outer wall of the bottom end of the round rod, and a spring is provided at the top of the ring. The spring is sleeved on the round rod, and the ring is located at the top of the side plate. Several slots are provided on the side plate, and the slots are adapted to the pins. The slots and the pins are coaxial.
[0010] As a further embodiment of this utility model, the slot and the sample feeding hole are on the same horizontal line, and the round rod is slidably connected to the L-shaped plate.
[0011] As a further embodiment of this utility model, a handle is fixedly connected to the top of the round rod.
[0012] The beneficial effects of this utility model are as follows:
[0013] By setting a label cap, a label with sample reagent information can be affixed to the top of the cap for identification and recording. Samples can be added to the sample wells through a circular hole. The position of the circular hole and label cap can be adjusted by moving the plate to ensure they are positioned on top of the sample wells. The label with sample reagent information is affixed to the top of the cap, making the reagent and sample information for each well clearly visible, reducing human error, and ensuring the accuracy of experimental data. This effectively solves the problem mentioned in the background art that most existing bioanalytical plates lack a mechanism for identifying and recording sample reagent information, easily leading to confusion of samples or reagents in different wells, resulting in sample misplacement or mix-up, affecting the accuracy of experimental results. In subsequent data analysis or verification, the lack of identification makes it difficult to trace the history of a sample, thus affecting the traceability and verifiability of the entire experiment. This invention effectively enhances the visibility and accuracy of identification, and complete identification records ensure the traceability of each experimental step, facilitating subsequent analysis and verification, and enhancing the reliability of experimental data.

[0020] 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.
[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] Reference Figure 1 - Figure 5A sample labeling mechanism for a bioanalytical plate includes a bioanalytical plate 1 with several sample wells 2. Side plates 3 are fixedly connected to the top of both ends of the bioanalytical plate 1. Each side plate 3 has a groove 4 on its adjacent side, and a slider 5 is installed within the groove 4. The slider 5 is adapted to the groove 4 and slidably connected to the side plate 3. A single movable plate 6 is fixedly connected to the two sliders 5 on their adjacent sides. The movable plate 6 has several circular holes 7, the distance between which is the same as the distance between the sample wells 2 on the bioanalytical plate 1. Several L-shaped fixing shafts 8 are fixedly connected to one side of the movable plate 6, and the L-shaped fixing shafts 8 are located on one side of the circular holes 7. A rotating shaft 9 is rotatably connected to the L-shaped fixing shaft 8, and a label cover 10 is fixedly connected to one side of the rotating shaft 9. By providing the label cover, a label with sample reagent information can be affixed to the top of the label cover for labeling and recording. Samples can be added to the sample wells through the circular orifice. The position of the movable plate can be adjusted to position the circular orifice and label cap so that they are located at the top of the sample well. A label with reagent information is affixed to the top of the label cap, making the reagent and sample information of each well clear at a glance, reducing human error, ensuring the accuracy of experimental data, and effectively solving the problem mentioned in the background art that most existing bioanalytical plates lack a mechanism for identifying and recording reagent information, which easily leads to confusion of samples or reagents in different wells, resulting in sample misplacement or confusion, affecting the accuracy of experimental results. In subsequent data analysis or verification, the lack of identification makes it difficult to trace the history of a sample, thus affecting the traceability and verifiability of the entire experiment. Therefore, this technology effectively enhances the visibility and accuracy of identification. Complete identification records ensure that each experimental step is traceable, which helps subsequent analysis and verification and enhances the reliability of experimental data.
[0023] In this embodiment, a lever 11 is fixedly connected to the top of the label cover 10 at the end away from the rotating shaft 9. By moving the lever 11, the label cover 10 can be flipped up, exposing the round hole 7, and the sample can be added into the sample hole 2 through the round hole 7.
[0024] In this embodiment, a baffle 12 is fixedly connected to the top of the L-shaped fixed shaft 8 on the side away from the moving plate 6. The baffle 12 is inclined. When the label cover 10 is opened, the label cover 10 is leaned against the baffle 12.
[0025] In this embodiment, two L-shaped plates 13 are fixedly connected to the top of both ends of the movable plate 6. A round rod 14 is passed through the L-shaped plate 13. A pin 15 is fixedly connected to the bottom of the round rod 14. A ring 16 is fixedly connected to the outer wall of the bottom end of the round rod 14. A spring 17 is provided on the top of the ring 16 and is sleeved on the round rod 14. The ring 16 is located on the top of the side plate 3. Several slots 19 are provided on the side plate 3. The slots 19 are adapted to the pins 15. The slots 19 and the pins 15 are coaxial. Through the cooperation of the pins 15 and the slots 19, the position of the movable plate 6 can be restricted to ensure that the position of the movable plate 6 will not shift when adding samples later, and to ensure that the round hole 7 and the sample adding hole 2 can remain coaxial.
[0026] In this embodiment, the slot 19 and the sample feeding hole 2 are on the same horizontal line. When the round rod 14 slides to connect the L-shaped plate 13 and inserts the pin 15 into the slot 19, the round hole 7 and the sample feeding hole 2 can be made coaxial.
[0027] In this embodiment, a handle 18 is fixedly connected to the top of the round rod 14. By pulling the handle 18, the round rod 14 is raised, thereby removing the pin 15 from the slot 19, which allows the moving plate 6 to be moved, and the round hole 7 to be moved to the top of the sample feeding hole 2.
[0028] Working principle: In use, slide block 5 is inserted into slide groove 4, allowing slide block 5 to move within slide groove 4. Pulling handle 18 raises handle 18, which in turn raises round rod 14. Round rod 14 then raises pin 15 and ring 16. The rising ring 16 compresses spring 17, causing spring 17 to contract, raising pin 15 until it is above side plate 3. This allows the lateral movement handle 18 to be moved, which in turn moves round rod 14, which in turn moves L-shaped plate 13, which in turn moves moving plate 6. Adjusting the position of moving plate 6, when pin 15 is moved to slot 19, release handle 18. The contracted spring 17 will then extend, allowing ring 16 to descend. Ring 16 then moves round rod 14, which in turn moves pin 15, allowing pin 15 to be inserted into slot 19 for restraint. The bottom of pin 15 is conical. With its shaped design, when the pin 15 descends, the tapered bottom surface of the pin 15 will first contact the side plate 3, allowing the pin 15 to smoothly insert into the slot 19. After the pin 15 is inserted into the slot 19, it can restrict the position of the moving plate 6. At this time, the round hole 7 is coaxial with the sample dispensing hole 2. Move the lever 11 to make the lever 11 drive the label cover 10 to rotate. The label cover 10 will drive the rotating shaft 9 to rotate on the L-shaped fixed shaft 8. Flip the label cover 10 open, and the sample can be added to the sample dispensing hole 2 through the round hole 7. Then move the label cover 10 again to cover the moving plate 6, blocking the round hole 7. At the same time, stick the label paper on the label cover 10 for identification, indicating the sample dispensing information, to avoid the experimenter forgetting the sample dispensing position and causing missed, wrong, or repeated sample dispensing. More sliders 5 can be installed on the side plate 3 so that each sample dispensing hole 2 has a round hole 7 and a label cover 10 at the top, so that more information can be marked.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
