Description

Technical Field

[0001] The present invention relates to the technical field of animal experiments, and specifically to a small animal experiment operation platform. Background Art

[0002] In the field of biotechnology, small animal experiments are an indispensable part of scientific research and teaching, and play a crucial role in aspects such as new drug research and development, physiological function research, and disease model construction.

[0003] When conducting small animal experiment operations, to ensure the accuracy of experimental data and the safety of the experimental process, small animals (such as mice, rats, rabbits, etc.) need to be stably fixed on the experimental operation platform. Although the existing small animal experiment operation platforms are provided with fixing measures such as straps and jigs, the positions of these fixing measures are often non-adjustable, lacking flexibility and unable to be adjusted according to the body size of the small animals to be experimented. As a result, in actual operation, larger-sized small animals cannot be fully stretched for fixation, while smaller-sized small animals may not be able to reach the fixing measures at the fixing parts (such as the legs), with poor applicability. In addition, in small animal experiment operations, the fixing positions of small animals are not fixed. Depending on different experimental designs, it may be necessary to flexibly adjust different parts such as the limbs, head, or torso of small animals for specific experimental operations, physiological index monitoring, or behavioral tests. Due to the limitations of the positions and quantities of the existing fixing measures on the operation platform, it is obviously difficult to meet such diverse fixing requirements, thus restricting the flexibility and precision of experimental operations.

[0004] Therefore, the present invention proposes a small animal experiment operation platform to solve the above problems. Summary of the Invention

[0024] Please refer to Figures 1 to 5 , a small animal experiment operation platform, including a table body 1, the table body 1 includes an operation area 101 for placing small animals for experimental operations, the bottom side of the operation area 101 is evenly provided with vertical rods 2, each of the vertical rods 2 can be independently lifted, and the operation platform further includes a plurality of pressing sheets 8 for sleeving on the vertical rods 2 to press and fix small animals.

[0025] It should be noted that the pressing sheet 8 includes various size specifications to adapt to the fixation requirements of small animals with different body sizes and different parts of small animals. For example, for thinner parts such as legs and tails, a smaller size pressing sheet 8 is selected, and for the neck and waist parts, a larger size pressing sheet 8 is selected. The experimenter adaptively selects according to the actual fixation requirements of the small animals to be experimented.

[0026] In the initial state, the upper ends of all the vertical rods 2 are flush with the bottom side of the operation area 101, making the bottom side of the operation area 101 in an overall flat state. After placing the small animal to be experimented in the operation area 101, determine the fixation part according to the actual size of the small animal's body and the experimental design (such as the leg joint part, neck part, etc. of the small animal), and then sequentially select the vertical rods 2 near the fixation part and move them up a certain distance. Then, sequentially put on the pressing sheet 8 adapted to the fixation part on the moved-up vertical rods 2, and fix the small animal by pressing the fixation part with the pressing sheet 2. Using the vertically arranged rods 2 evenly distributed in a dot matrix as fixation anchor points, and then putting on the pressing sheet 8 for pressing and fixation, thus adapting to the fixation requirements of different body sizes and customizing the fixation part, greatly improving the flexibility and accuracy of small animal experiment operations.

[0027] Please refer to Figure 4 and Figure 5 In an embodiment of the present invention, a through hole 11 adapted to the vertical rod 2 is provided on the pressing sheet 8, and the pressing sheet 8 is sleeved on the vertical rod 2 through the through hole 11. A hand-tightening bolt 9 is further provided on the pressing sheet 8 to position the pressing sheet 8 by tightening the hand-tightening bolt 9.

[0028] In this embodiment, when sleeving the pressing sheet 8, align the through hole 11 on the pressing sheet 8 with the upper end of the vertical rod 2, then move the pressing sheet 8 downward so that the upper end of the vertical rod 2 passes through the through hole 11. Subsequently, continue to move the pressing sheet 8 downward and rotate it to adjust the pressing sheet 8 to press on the small animal fixation part with an appropriate pressure and angle. Finally, tighten the hand-tightening bolt 9 to position the pressing sheet 8.

[0029] Furthermore, in this embodiment, the pressing sheet 8 is arched.

[0030] Furthermore, in this embodiment, a soft pad 12 is further provided on the pressing sheet 8 to reduce the direct pressure of the pressing sheet 8 on the small animal and avoid causing pain to it.

[0031] Please refer to Figures 1 to 3 In an embodiment of the present invention, the table body 1 further includes a liquid dropping cavity 102 for collecting experimental waste liquid. The liquid dropping cavity 102 is located below the operation area 101, and liquid dropping holes 5 communicating with the liquid dropping cavity 102 are evenly distributed on the bottom side of the operation area 101. A liquid discharge port is further provided on one side of the liquid dropping cavity 102.

[0032] In this embodiment, the waste liquid (such as blood, flushing wastewater, etc.) generated during the small animal experiment operation falls into the liquid collecting cavity 102 through the lower liquid hole 5 for collection, and is then discharged and cleaned through the liquid discharge port.

[0033] Please refer to Figure 1 , in an embodiment of the present invention, the table body 1 further includes a sewage collecting cavity 105 communicated with the operation area 101 for collecting experimental garbage (such as cut small animal tissues, etc.). A cleaning port (not shown in the figure) is provided on one side of the sewage collecting cavity 105. After the experiment is completed, the experimental garbage in the operation area 101 is brushed into the sewage collecting cavity 105 through tools (such as a brush), and is then discharged and cleaned through the cleaning port.

[0034] Please refer to Figure 1 and Figure 3 , in an embodiment of the present invention, the table body 1 further includes a positioning cavity 103 and an installation cavity 104. The lower end of the vertical rod 2 penetrates through the upper side of the positioning cavity 103 and is located in the positioning cavity 103. The length of the vertical rod 2 is configured such that when the upper end of the vertical rod 2 is flush with the bottom surface of the operation area 101, the lower end of the vertical rod 2 abuts against the inner bottom side of the positioning cavity 103. Paraffin 3 is filled in the positioning cavity 103. A sealing rubber ring 6 is provided in the hole formed by the penetration of the upper side of the positioning cavity 103 by the vertical rod 2. A temperature control member 4 for heating / cooling the paraffin 3 is provided in the installation cavity 104. Preferably, the temperature control member 4 is a semiconductor refrigeration sheet, and the paraffin 3 is heated / cooled by changing the current. Of course, the temperature control member 4 can also be other combined structures with heating and cooling functions as long as the heating / cooling function of the paraffin 3 can be realized.

[0035] A limiting piece 10 is provided on the vertical rod 2 to prevent the lower end of the vertical rod 2 from detaching from the positioning cavity 103.

[0036] In this embodiment, when performing small animal experiment operations, first heat the paraffin 3 through the temperature control member 4 to melt it, so that the vertical rod 2 can move upward. Determine the fixing position according to the actual size of the small animal's body and the experimental design. Select the vertical rods 2 near the fixing position in sequence and move them upward by a certain distance (it should be noted that the sealing rubber ring 6 can apply a certain extrusion force to the vertical rod 2, so that after the vertical rod 2 moves upward, without external force, the vertical rod 2 will not move downward under its own gravity). After determining that all the vertical rods 2 have moved upward, then cool the paraffin 3 through the temperature control member 4 to solidify it. The solidified paraffin coats the rod section of the vertical rod 2 located in the positioning cavity 103 and the limiting piece 10 to position the vertical rod 2, so as to be able to perform the subsequent operation of fixing the small animal with the set pressing piece 8; it should be further noted that after the small animal experiment operation is completed, the upward-moved vertical rod 2 does not need to be reset, and it will be reset during the next small animal experiment (during the experiment, the paraffin 3 will inevitably be heated to melt first, and then the target vertical rod 2 will be selected and moved upward according to the actual size of the small animal's body and the experimental design), thereby reducing the heating of the paraffin 3 by the temperature control member 4 once and saving energy consumption.

[0037] Further, in this embodiment, the sealing rubber ring 6 is made of high-temperature resistant materials such as silicone rubber and fluororubber, so as to maintain stable sealing performance when the paraffin 3 is heated and melted.

[0038] Please refer to Figure 4 and Figure 6 , in an embodiment of the present invention, the operation platform further includes a pulling member 13 for pulling out the vertical rod 2. A first magnetic member 7 is embedded at the upper end of each vertical rod 2. The pulling member 13 includes a hand-held rod 1301 and a second magnetic member 1302 provided at one end of the hand-held rod 1301.

[0039] In this embodiment, the experimenter holds the hand-held rod 1301 by hand to make the second magnetic member 1302 dock and magnetically attract the first magnetic member 7 on the target vertical rod 2, and then pulls up the hand-held rod 1301 to pull out and move up the vertical rod 2. The operation is simple and convenient to use.

[0040] In addition, it should be understood that although this specification is described according to embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
