Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory equipment, and particularly relates to a multi-color light source light and shadow type centrifuge tube fixing device. Background Art

[0002] In experimental science, particularly in biochemistry and molecular biology, centrifuge tubes are commonly used laboratory vessels, and the addition and mixing of liquids within them is extremely frequent and important. These operations often involve the addition of minute amounts of liquid, such as just a few microliters, and often require multiple additions of different reactants. Furthermore, due to the continuous and repetitive nature of scientific research, experimenters often need to perform multiple batches of the same experimental procedure.

[0003] However, in existing experimental procedures, due to various reasons such as sudden interruption of the experiment, forgetfulness or lack of concentration of the experimenter, operational errors such as omission, over-addition, and mistaken addition often occur. These errors may not only lead to deviations in experimental results, but in serious cases, they may even completely undermine the correctness of the experiment, resulting in waste of drugs and loss of time.

[0004] To avoid these issues, experimenters often employ supplementary methods, such as using pen and paper to record sample additions or using electronic devices for reminders. However, these methods still have limitations. For example, pen and paper recording requires the experimenter to frequently shift their gaze and attention, increasing the risk of operational errors. While electronic devices can provide more convenient reminders, they can also malfunction due to complex operation or battery depletion.

[0005] In the existing technology, there are also some attempts to improve the centrifuge tube sampling operation. For example, application number CN201921326566.8 discloses a centrifuge tube rack that is convenient for observing the sample addition liquid level. The centrifuge tube rack is designed with an observation groove and a reflector so that the experimenter can observe the liquid level in the centrifuge tube. However, this design still has certain difficulties in judging the accuracy of micro-sampling, and cannot provide an accurate record of the number of sample additions. In addition, application number CN201921109467.4 discloses a modular centrifuge tube rack with a UV ultraviolet lamp, which is equipped with a UV ultraviolet lamp to disinfect and sterilize the centrifuge tube to reduce the risk of contamination by miscellaneous bacteria. However, this type of design also cannot solve the problems of mis-addition, omission, and over-addition during the sampling process.

[0006] Therefore, it is necessary to design a new type of centrifuge tube rack at this stage, which can not only meet the basic use needs of experimenters for centrifuge tubes, but also provide functions to prevent accidental addition, missed addition, and over-addition, and provide reminders through sensory feedback, so as to reduce errors in experimental operations and improve the accuracy and reliability of experimental results. Utility Model Content

[0007] To address the potential for experimental errors such as mis-addition, omission, and over-addition during multiple sample additions by researchers conducting large-scale, multi-batch experiments using centrifuge tubes, we utilize a push-button switch at the bottom of the centrifuge tube to activate the color change of a ring-shaped, multi-color LED light. This allows for accurate monitoring of sample addition times and monitoring of sample volume, ultimately avoiding experimental errors and improving precision and accuracy.

[0010] As a further supplement to the above technical solution, an engaging groove is provided on the side wall of the porous placement box, and an engaging block corresponding to the engaging groove is provided on the side wall of the light source support box. The engaging groove and the engaging block are embedded in each other to realize the assembly of the porous placement box and the light source support box, thereby preventing relative slippage of the two during assembly and causing operational errors.

[0011] As a further supplementary explanation of the above technical solution, a first slot is provided on both sides of the master control switch circuit board, and a second slot is provided on both sides of the array light source circuit board.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. This utility model uses a push-button switch at the bottom of the centrifuge tube to trigger the color change of a ring-shaped multi-color LED light. This allows the experimenter to indicate the number of sample additions by changing the light color, providing intuitive progress feedback. Furthermore, the ring-shaped multi-color LED light not only illuminates the sample liquid, but also allows for clear observation of changes in the liquid volume within the centrifuge tube, reducing sample addition errors. Therefore, this utility model enables monitoring of the number of sample additions and observation of sample liquid volume, avoiding experimental errors and thus improving the detection precision and accuracy of experimental samples.

[0018] 2. The support tube design of this utility model creates space between the array light source circuit board and the master control switch circuit board.

At the same time, this design also makes cleaning the device simpler and more effective, improving the efficiency of use.

[0020] 4. The setting of the first notch and the second notch of the utility model and the coordinated use of the bite groove and the bite block greatly simplify the installation and disassembly process of the circuit board, and also enhance the connection stability between the porous placement box and the light source support box, making the operation of the entire device easier and more reliable.

DETAILED DESCRIPTION

[0027] In order to further illustrate the technical solution of the present invention, Figures 1 to 5 According to the design scheme and specific implementation process, we further illustrate the utility model through four embodiments.

[0028] Example 1

[0029] As attached Figures 1 to 5As shown, a multi-color light source light and shadow type centrifuge tube fixing device includes a porous placement box 1 and a light source support box 2, wherein the porous placement box 1 is arranged on the light source support box 2, and a battery compartment box 3 and a corresponding battery box cover 5 are arranged on the light source support box 2, and cylindrical batteries 4 are arranged in the battery compartment box 3. A master control switch circuit board 9 and an array light source circuit board 12 are installed in the light source support box 2 by bolts, and a plurality of push-type switches 10 and a power switch 11 for controlling the on and off of the entire circuit are arranged in an array on the master control switch circuit board 9, a through hole 6 is provided on the light source support box 2, and the power switch 11 is embedded in the through hole 6, and the plurality of push-type switches 10 are electrically connected to the battery compartment box 3 through the power switch 11, and a porous contact box cover 15 is provided on the array light source circuit board 12. A metal shrapnel 16 is provided in each hole of the porous contact box cover 15, and a plurality of ring-shaped multi-color LED lights 14 are provided on the array light source circuit board 12 located directly below each of the metal shrapnel 16 through a tube sleeve 13. The button of the push-type switch 10 passes through the tube sleeve 13, and its wiring terminal is electrically connected to the ring-shaped multi-color LED light 14. A first embedding groove 20 is provided on the array light source circuit board 12, and a second embedding groove 21 is provided on the porous contact box cover 15. The first embedding groove 20 and the second embedding groove 21 are both used to embed the power switch 11. Support tubes 17 are provided at the bottom of the four corner mounting holes of the array light source circuit board 12. The array light source circuit board 12 leaves space with the master control switch circuit board 9 through the support tube 17 for accommodating the push-type switch 10.

[0030] As a preferred implementation of this embodiment, snap blocks 18 are respectively provided on both sides of the array light source circuit board 12, and snap grooves 19 corresponding to the snap blocks 18 are provided on the porous contact box cover 15, and the porous contact box cover 15 is snap-mounted on the array light source circuit board 12.

[0031] In this embodiment, the multi-well storage box 1 is made of a translucent material and can be configured in various sizes, including 32, 60, and 90 wells. It is used to store 1.5ml and 2ml microcentrifuge tubes, as well as 200ul centrifuge tubes. Furthermore, the light source holder 2, battery compartment 3, and battery compartment cover 5 are preferably constructed of transparent acrylic plastic.

[0032] It should be noted that the above solution is a preferred solution and cannot be regarded as the only solution by those skilled in the art. Therefore, without departing from the spirit or basic features of the present invention, the inventive ideas and design concepts of the present invention can be implemented in other specific forms and should be equally included in the scope of protection disclosed in the technical solution of the present invention.

[0033] The experimenter places the centrifuge tube 24 in the porous placement box 1. After each operation, the metal spring 16 can be pressed downward by the bottom of the centrifuge tube 24 to trigger the push-type switch 10 to change the light color of the ring-shaped multi-color LED light 14. It is used to indicate the number of sample additions, remind the experimenter of the sample addition progress, and observe the volume change of the liquid in the test tube, which helps to reduce the error of sample addition. At the same time, the ring-shaped multi-color LED light 14 facilitates direct observation of the sample liquid by providing light, increasing the error feedback path. If the indicator light is not uniform after the sample liquid is added, it can remind the operator to review the sample addition process, reducing errors.

[0034] Example 2

[0035] As attached Figure 3 As shown, first notches 22 are provided on both sides of the master switch circuit board 9, and second notches 23 are provided on both sides of the array light source circuit board 12. When installing or removing the master switch circuit board 9 or the array light source circuit board 12, the user only needs to insert or remove the circuit board from the light source holder 2 through the corresponding first notch 22 or second notch 23. This design makes it easier to remove the circuit board.

[0036] Example 3

[0037] As attached Figure 3 As shown, in order to ensure a stable connection between the porous placement box and the light source support box. A bite groove 8 is carefully designed on the side wall of the porous placement box 1, and correspondingly, a bite block 7 is set on the side wall of the light source support box 2. When assembly is required, the user only needs to accurately embed the bite block 7 into the bite groove 8. Through this mutual embedding cooperation, the porous placement box 1 and the light source support box 2 can be firmly assembled together. This design not only improves the convenience of assembly, but more importantly, it effectively prevents the relative slippage that may occur between the two during the assembly process, thereby avoiding errors caused by improper operation.

[0038] Therefore, this matching structure of the bite groove and the bite block not only simplifies the assembly process, but also greatly improves the stability and accuracy of the assembly, bringing users a more convenient and reliable use experience.

[0039] Example 4

[0040] Based on the above embodiment, an anti-corrosion layer is provided on the surface of the porous contact box cover 15, and the anti-corrosion layer covers the metal shrapnel 16. The anti-corrosion layer is made of high-quality materials such as PE or PTFE. Both materials have good chemical stability and corrosion resistance, and can effectively resist the erosion of foreign pollutants, thereby protecting the metal shrapnel from damage.

[0041] Because metal domes are a crucial component of lighting systems such as push-button switches, power switches, and ring-shaped multi-color LED lights, protecting them is crucial to maintaining the proper functioning of the entire device. Adding an anti-corrosion layer effectively prevents corrosion on the metal domes, ensuring stable operation of the entire lighting system.

[0042] This anti-corrosion coating also offers another benefit: it prevents residual liquid from accumulating in the centrifuge tube placement holes. During experimental operations, some liquid often remains in the centrifuge tubes or placement holes. If the porous contact box lid lacks an anti-corrosion coating, this residual liquid could corrode the metal dome. However, with the protection of the anti-corrosion coating, even some residual liquid will not damage the metal dome.

[0043] More importantly, the presence of the anti-corrosion layer makes cleaning the centrifuge tube placement device faster and more effective. After each experiment, a simple rinse of the device is all that is needed to completely remove residual liquid, without the worry of residual liquid causing long-term damage to the metal shrapnel.

[0044] The above shows and describes the main features and advantages of the present invention. It will be apparent to those skilled in the art that the specific embodiments of the present invention are not limited to the details of the above exemplary embodiments. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing description, and all variations that come within the meaning and range of equivalents of the claims are intended to be included within the present invention.

[0045] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
