Description

Technical Field

[0001] This utility model relates to the field of biomedical technology, specifically to a multifunctional experimental tool board. Background Technology

[0002] In daily life and biomedical experimental work, the reproducibility of experimental results is one of the core indicators for measuring the scientific rigor and reliability of an experiment. It is influenced by a variety of factors, including the experimental environment, instrument precision, experimental time control, the effects of gravity, and the level of operational standardization by the personnel. To obtain ideal and reproducible experimental results, researchers need to frequently adjust to these influencing factors and conduct multiple parallel experiments. Therefore, in this process, researchers rely on various experimental auxiliary tools to ensure the smooth progress of experimental operations and the accuracy of experimental data. For example: When adjusting instrument accuracy, pipette repair tools are required for pipette calibration and maintenance. To ensure the experimental platform is level and eliminate the interference of gravity, a level is necessary. When handling experimental consumables or setting up experimental apparatus, cutting tools may be needed for trimming, or Allen wrenches may be required for disassembling and securing components. Furthermore, as experimental scale expands, in large-scale experiments, researchers often need to manually open and close the caps of consumables such as eight-tube strips and centrifuge tubes. This operation is not only extremely labor-intensive and time-consuming, but also prone to causing finger fatigue, wear, and even injury due to repetitive actions, negatively impacting the health of the researchers' hands. However, most of the experimental auxiliary tools mentioned above are designed independently and separately. During the experiment, the experimenters need to carry, find and use the corresponding tools according to different experimental needs. This not only increases the burden of carrying and the complexity of operation for the experimenters, but may also affect the experimental efficiency and progress due to the omission of tools or the excessive time spent in finding them.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: In this invention, the design of the three protruding wrench and the internal hex socket on the tool plate makes it convenient for laboratory personnel to engage the three protruding wrench or tighten the internal hex socket in accordance with the maintenance operation specifications of the single-channel pipette, thereby completing the installation, fixing, accuracy calibration and component unloading of the single-channel pipette, thus ensuring the accuracy of the single-channel pipette during use, saving time and effort.

[0015] In this invention, a small cylindrical level is placed in the leveling slot on the tool plate, which makes it easier for the experimenter to observe the levelness according to the level and correct the multichannel split pipette to a horizontal state, thereby improving the accuracy of the split pipette when in use.

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figures 1-4 As shown, this utility model provides a multifunctional experimental tool board, including a tool board body 1. The tool board body 1 has four side segments, which are integrally enclosed to form the outline of the tool board body 1. The middle part of the tool board body 1 is hollow, and a handle section 2 is provided in the middle part of the tool board body 1, which is integrally connected to the corresponding two side segments. The hollow shape is divided into a first cavity 12 and a second cavity 13 by the handle section 2. The design of the first cavity 12 and the second cavity 13 makes it easy for the experimenter to grasp the handle section 2, so as to facilitate the experimenter to use the multifunctional experimental tool board efficiently and accurately. A support area 3 is provided at one end of the surface of the handle section 2, and a thermometer placement slot 4 is provided on the other side of the surface of the handle section 2 corresponding to the support area 3.

[0033] The tool board 1 has four sides: a first side, a second side, a third side, and a fourth side. Several protruding wrenches 5 are connected to the outer edge of the first side. A level placement slot 6 is provided on the surface of the first side. This level placement slot 6 allows the multi-functional experimental tool board to mount a commercially available small cylindrical level, ensuring the relative level of multi-channel pipettes when calibrating them in the laboratory, thus improving the accuracy of experimental results. A blade placement area 7 is provided on the surface of the second side, and a calibration tool is provided on the outer edge of the third side. The fourth side section has a three-protruding wrench 9 and an internal hex socket 10 integrally connected to its surface. The dimensions of the three-protruding wrench 9 and the internal hex socket 10 are adapted to commercially available single-channel pipettes. The design of the three-protruding wrench 9 and the internal hex socket 10 is mainly to facilitate the adjustment and calibration of commercially available single-channel pipettes. Specifically, the experimenter can complete the installation, fixation, accuracy calibration, and component unloading of the single-channel pipette by engaging the three-protruding wrench 9 and unscrewing the internal hex socket 10, ensuring the accuracy of the single-channel pipette during use. The surface of the fourth side section also has several internal hex sockets 11.

[0034] Specifically, the calibration wrench 8 is used to assist in the calibration of experimental instruments. It is designed to be compatible with precision instruments commonly used in biomedical experiments (such as pipettes and multi-channel dispensing devices), addressing the pain point of researchers needing to find additional specialized calibration tools during instrument calibration. Furthermore, the calibration wrench 8 complements other components such as the three-protruding wrench 9 and the internal hexagonal socket 10 on the tool plate 1, jointly ensuring the convenience and accuracy of instrument calibration. Its specific operation is as follows: Preliminary preparation: Place the experimental instrument to be calibrated on a stable experimental platform and ensure that the instrument is in a state of need of calibration.

[0035] Wrench usage and positioning: Hold the experimental tool board firmly at the handle section 2, and then align the calibration wrench 8 with the calibration interface or adjustment component of the instrument to be calibrated. Its size and shape are designed to fit the calibration points of common experimental instruments, and precise engagement can be achieved without additional adjustments.

[0036] Calibration Operation: According to the instrument calibration specifications, the instrument parameters are gradually adjusted by rotating, prying or pushing the calibration wrench 8 to finely operate the instrument's precision adjustment components (such as the piston positioning component of the pipette and the flow adjustment plug of the diversion device). During this process, the instrument's horizontal status can be observed in conjunction with the small cylindrical level in the leveling slot 6 on the tool plate 1 to ensure the stability of the instrument's reference during calibration and improve calibration accuracy.

[0037] Post-operation storage: After calibration, there is no need to store the calibration wrench 8 separately, as it is integrated with the tool board body 1. The multi-functional experimental tool board can be placed directly in the designated area of ​​the experimental table to avoid the wrench being lost or confused, achieving immediate storage after use.

[0038] As a further step, the first side segment is arranged opposite to the third side segment, and the second side segment is arranged opposite to the fourth side segment. One end of the grip segment 2 is integrally connected to the second side segment, and the other end of the grip segment 2 is integrally connected to the fourth side segment. The support area 3 on the grip segment 2 is close to the second side segment. The support area 3 is composed of a front baffle 31 and a rear back plate 32. Both the front baffle 31 and the rear back plate 32 are inclined, and a placement cavity is provided between the front baffle 31 and the rear back plate 32.

[0039] Specifically, the placement cavity in the support area 3 allows for the tilting of mobile phones or tablets, increasing the practicality of the experimental tool board proposed in this invention. Specifically, it facilitates the support of mobile phones or tablets during experiments, allowing experimenters to view relevant materials or observe experimental steps simultaneously, reducing the error rate. Furthermore, the placement of the support area 3 near the second side avoids interference with other functional components on the tool board and also facilitates operation via the grip section 2. It should be noted that the grip section 2, in actual production, must be designed according to the physiological characteristics of an adult hand, including its curvature, length, and width, to improve user comfort and reduce the risk of finger injury and fatigue during prolonged operation. This production technology can be achieved using commercial equipment, which will not be elaborated upon here. This paper aims to protect the physical structure of the multifunctional experimental tool board.

[0040] As a further step, the blade placement area 7 includes a blade placement groove 71 formed on the outer edge of the second side section and a blade fixing hole 72 extending through the surface of the second side section, the blade fixing hole 72 communicating with one end of the blade placement groove 71.

[0041] Specifically, the blade placement slot 71 is designed based on commercially available utility knife blades. The size of the blade placement slot 71 is slightly larger than the size of the utility knife blade so that it can accommodate one commercially available utility knife blade. This allows for convenient cutting and trimming of commercially available suction tips or silicone tubes. After the operation is completed, when no longer needed, the commercially available utility knife blade can be simply inserted into the blade placement slot 71 with the blade facing inward to store it, thus reducing safety hazards.

[0042] As a further step, the support area 3, the three-protruding wrench 9, and the internal hex socket 10 are respectively located on the opposite side of the tool plate 1, opposite to the surface where the thermometer placement slot 4 is located. The thermometer placement slot 4 is used to accommodate a commercially available thermometer, which allows researchers to easily measure the ambient temperature. The specific reason for this design is that fluid pressure and flow rate are significantly affected by temperature. Therefore, it is necessary to read the ambient temperature in real time during the experiment and adjust the experimental conditions based on the temperature data to ensure the normal conduct of the experiment.

[0043] The bracket area 3, the three-protruding wrench 9, and the hex socket 10 are positioned on the opposite side of the surface where the thermometer placement slot 4 is located. This makes the side of the tool board 1 facing the thermometer placement slot 4 a flat surface. All the protruding components, including the bracket area 3, the three-protruding wrench 9, and the hex socket 10, are concentrated on the other side of the tool board 1, facilitating the stable placement of the tool board 1. At the same time, the distribution of the bracket area 3, the three-protruding wrench 9, and the hex socket 10 on the protruding surface of the tool board 1 ensures that the various functional components do not interfere with each other during use, making it highly practical.

[0044] Furthermore, several hexagonal socket wrench sockets 11 are located on one side of the hexagonal sleeve 10, and the inner diameters of the hexagonal socket wrench sockets 11 are all different. Specifically, at least two hexagonal socket wrench sockets 11 are provided to ensure that the multifunctional experimental tool board proposed in this utility model can be used to screw various specifications of hexagonal screwdriver bits. Moreover, the attached drawings of this solution propose five specifications of hexagonal socket wrench sockets 11, which can increase the practicality of the experimental tool board when making reasonable use of space layout. The inner cavity of the hexagonal sleeve 10 is opened through the surface of the fourth side section, and the hexagonal sleeve 10 is located between the three-protruding wrench 9 and the hexagonal socket wrench 11. It is worth noting that there is an area left between the three-protruding wrench 9 and the hexagonal sleeve 10 on the tool board body 1 for printing the brand logo, so as to meet the needs of manufacturer brand logo display, product recognition enhancement and brand communication and promotion.

[0045] As a further step, several protruding wrenches 5 are arranged in a row along the outer edge of the first side segment, and the spacing between each pair of adjacent protruding wrenches 5 is equal. Specifically, the design dimensions of the several protruding wrenches 5 correspond to the dimensions of the commercially available eight-tube connector, which makes it easy for experimental personnel to pry off the matching and commercially available eight-tube connector switch cover during the experiment, which is simple, quick, and indirectly improves the experimental efficiency.

[0046] Working principle and usage process of this utility model: First, install the commercially available small cylindrical spirit level into the spirit level placement slot 6, and the thermometer into the thermometer placement slot 4 at the bottom of the tool board 1. Place the utility knife blade into the blade placement slot 71 and secure it through the blade fixing hole 72 to prevent it from slipping out. Specifically, because the utility knife blade has a hole, after placing it into the blade placement slot 71, a binding thread (such as a cable tie) can be passed through the blade fixing hole 72 and simultaneously through the hole on the utility knife blade to secure it firmly within the blade placement slot 71. It should be noted that because the inner cavity of the blade placement slot 71 is slightly larger than the utility knife blade, once the utility knife blade is retracted into the blade placement slot 71, simply restricting the hole on the utility knife blade will prevent it from slipping out. It is worth noting that the blade fixing hole 72 in this diagram is a strip-shaped hole, which is mainly to accommodate the use of flexible cable ties. When using flexible cable ties, the cable tie size is one that can pass through the hole on the utility knife blade, i.e., a small cable tie. The length of the small cable tie can be trimmed during use, which satisfies the need for fixing without affecting the overall operation and use of the experimental tool board. This article will not explain this further.

[0047] For single-channel pipettes: When it is necessary to install, calibrate, or remove a single-channel pipette, the experimenter holds the handle section 2 and uses the three-pronged wrench 9 and the internal hex socket 10 to engage the three-pronged wrench 9 or loosen the internal hex socket 10 according to the pipette maintenance operation specifications to complete the installation, fixation, accuracy calibration, and component removal of the pipette. This ensures the accuracy of the single-channel pipette during use and saves time and effort.

[0048] For multichannel pipettes: When using the multifunctional experimental tool board to operate the multichannel pipette, the level can be observed first using the small cylindrical spirit level in the leveling slot 6 to adjust and correct the multichannel pipette to a horizontal state; when it is necessary to remove the switch cover on the eight-tube connector, the experimenter can hold the handle section 2 and use the multiple protruding wrenches 5 to align with the corresponding position of the eight-tube connector, and gently pry open the switch cover, which is simple and quick, avoiding the problem of finger injury from opening a large amount of the cover.

[0049] For trimming the suction tip and silicone tube: Researchers can first remove the adjustable cable ties to access the utility knife blade in the blade holder 71, allowing for trimming. After trimming, insert the blade blade into the holder 71 with the blade facing inwards and secure it again with the adjustable cable ties to complete storage, preventing the blade from being exposed and posing a safety hazard. It is important to emphasize that trimming the suction tip and silicone tube is not necessary for every experiment; the utility knife blade is stored as a precaution.

[0050] For tightening hex screwdriver bits: According to the specifications of the hex screwdriver bit, the experimenter holds the handle section 2 and selects the corresponding hex socket 10 or hex wrench socket 11 to tighten the bit. This can assist in completing the instrument assembly or maintenance, and meet the needs of integrated multi-functional experimental tool boards for instrument assembly, component fixation, etc.

[0051] For use with electronic devices: By attaching the flat surface of the tool board 1 to the desktop, a mobile phone or tablet can be placed in the support area 3, so that the experimenter can easily view relevant information or perform experimental operations according to the experimental steps provided on the electronic device during the experiment, which has a certain degree of practicality.

[0052] Regarding the experimental environment: During the experiment, the experimenters can read the ambient temperature in real time through the thermometer at the bottom of the tool board 1, which provides data support for analyzing the correlation between fluid pressure, flow rate and temperature, and helps to control the experimental conditions to ensure the normal conduct of the experiment.
