Description

Technical Field

[0001] The utility model relates to the technical field of rat experiments, and particularly relates to a rat experiment fixing device. Background Technique

[0002] The rat moxibustion experiment is an experimental method that uses moxibustion therapy to treat or study rats under laboratory conditions. In the rat moxibustion experiment, researchers can evaluate the effect and mechanism of moxibustion by observing the reactions and physiological changes of rats. When conducting a rat moxibustion experiment, in order to avoid the influence of the violent activities of rats on the moxibustion situation, a fixing device is needed to fix the rats.

[0003] The traditional fixing method is to fix the four limbs of the rat on the experimental table by using positioning ropes to ensure the smooth progress of the rat moxibustion experiment; however, due to the overly simple fixing structure and the long distance between the fixed end of the positioning rope and the pulling point, with a large degree of freedom of movement, it is difficult to effectively fix the four limbs of the rat during use; after retrieval, the patent number CN215080117U discloses a multifunctional rat fixator for experiments, including a partition board, and a fixing component is also provided at the rear side of the partition board. The fixing component includes: a left side board for fixing the left trunk of the rat, a right side board for fixing the right trunk of the rat, a rear partition board for fixing the abdomen of the rat, and a cover board for pressing the trunk of the rat; acupuncture holes corresponding to the acupoints of the rat are provided on the left side board, the right side board and the cover board; this fixator can make the rat lie on its back more easily, is easy to operate, has a lower stimulation to the rat, and the rat is easy to cooperate. Multiple moxa cones can be used simultaneously to moxibust different acupoints; acupuncture holes are provided on the left side board, the right side board and the cover board, which is convenient for acupuncture after fixation. At the same time, the acupuncture holes on different models of cover boards correspond to the acupoints of rats of corresponding body types, and the accuracy of the acupuncture position can be ensured through the acupuncture holes. However, in specific use, there are still:

[0004] 1. Since there are differences in the volumes of different experimental rats, and the above device needs to use cover boards of corresponding models to adapt to the acupoints of the rats, this not only requires the experimenter to prepare multiple groups of cover boards, but also the experimenter needs to check the acupoints of the rats correspondingly before using the cover board to select the cover board, which will undoubtedly increase the experimental burden of the experimenter and affect the efficiency of the rat moxibustion experiment;

[0005] 2. The above experimental device cannot adjust the fixing position of the rat according to the volume of the experimental rat when in use, so it cannot effectively fix the rat, affecting the experimental efficiency and experimental results.

[0006] Therefore, the utility model proposes a rat experiment fixing device to solve the above problems existing in the background technique. Summary of the Invention

[0017] Preferably, the vertical cross-sectional shapes of the inner side of the second sliding sleeve and the cross bar are both matching rectangles, which can prevent the moxibustion mold from rotating and make the operation of the moxibustion mold more stable.

[0018] Preferably, five second sliding grooves are formed in the top of the mounting plate. The structures of the head fixing device and the limb fixing device are the same. The head fixing device includes a threaded sleeve slidably connected inside the adjacent second sliding groove. A retractable tie strap is fixedly connected to the top of the threaded sleeve. The combined use of the head fixing device and the limb fixing device can fix the head and limbs of the rat, so as to facilitate the normal progress of moxibustion operation.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution: a rat experiment fixing device, including:

[0031] Mounting plate 1, on the surface of the mounting plate 1 is mounted a head fixing device 2, and on the surface of the mounting plate 1 are mounted four limb fixing devices 3;

[0032] Moxibustion auxiliary device 4, the moxibustion auxiliary device 4 is mounted on the surface of the mounting plate 1.

[0033] As a preferred embodiment, as Figure 2 , Figure 3 and Figure 4As shown in the figure, both ends of the mounting plate 1 are provided with first sliding grooves 11. The moxibustion assisting device 4 includes two sliders 41 that are respectively slidably connected to the interiors of the two first sliding grooves 11. The top of the slider 41 is fixedly connected with a sliding bar 42. The surface of the sliding bar 42 is slidably connected with a first sliding sleeve 43. A cross bar 44 is fixedly connected between the two first sliding sleeves 43. The surface of the cross bar 44 is slidably connected with a second sliding sleeve 45. The surface of the second sliding sleeve 45 is fixedly connected with a moxibustion mold 46. One end of the first sliding sleeve 43 is threadedly connected with a first threaded column 47. One end of the first threaded column 47 penetrates through the first sliding sleeve 43 and contacts the sliding bar 42. One end of the slider 41 is threadedly connected with a second threaded column 48. One end of the second threaded column 48 penetrates through the slider 41 and contacts the first sliding groove 11. The slider 41 and the first sliding groove 11 are both convex shapes that match each other. The top of the second sliding sleeve 45 is threadedly connected with a third threaded column 49. The bottom of the third threaded column 49 penetrates through the second sliding sleeve 45 and contacts the cross bar 44. The vertical cross-sectional shapes of the inner side of the second sliding sleeve 45 and the cross bar 44 are both rectangles that match each other.

[0034] As a preferred embodiment, as Figure 2 and Figure 3 shown in the figure, the top of the mounting plate 1 is provided with five second sliding grooves 12. The structures of the head fixing device 2 and the limb fixing device 3 are the same. The head fixing device 2 includes a threaded sleeve 21 that is slidably connected to the interior of an adjacent second sliding groove 12. The top of the threaded sleeve 21 is fixedly connected with a retractable tie 22. A threaded adjusting rod 23 that is rotationally connected to the second sliding groove 12 is threadedly connected to the interior of the threaded sleeve 21. One end of the threaded adjusting rod 23 penetrates through the second sliding groove 12 and extends to the outside of the mounting plate 1.

[0035] The staff can rotate the threaded adjusting rod 23 in the corresponding direction. The threaded adjusting rod 23 drives the threaded sleeve 21 to move along the interior of the second sliding groove 12. The threaded sleeve 21 drives the retractable tie 22 to move to the designated position. This enables the head fixing device 2 and the limb fixing device 3 to be applicable to rats of different sizes, further expanding the overall practicality of the rat experiment device.

[0036] When the rat experiment fixing device of the present utility model is in use, the experimenter first places the head and limbs of the rat into the corresponding retractable ties 22 respectively, and then tightens the retractable ties 22 to fix both the head and limbs of the rat. At this time, the rat is firmly locked on the top of the mounting plate 1. Then the experimenter can place the lit moxa into the moxibustion mold 46 to perform normal moxibustion operations on the rat.

[0037] When the experimenter needs to adjust the horizontal position of the moxibustion, the experimenter first externally rotates the second threaded column 48 so that the second threaded column 48 is separated from the first chute 11. At this time, the slider 41 loses resistance, and the experimenter can slide the slider 41. The slider 41 slides the moxibustion mold 46 to the corresponding position through the slide bar 42, the first sliding sleeve 43, the cross bar 44 and the second sliding sleeve 45. Then, the second threaded column 48 is rotated back until the second threaded column 48 abuts against the first chute 11. Then, the third threaded column 49 is externally rotated so that the third threaded column 49 is separated from the cross bar 44. At this time, the second sliding sleeve 45 loses the block, and the staff can drive the moxibustion mold 46 to slide to the corresponding position through the second sliding sleeve 45. Then, the third threaded column 49 is rotated back until the third threaded column 49 abuts against the cross bar 44;

[0038] When the experimenter needs to adjust the vertical position of the moxibustion, first externally rotate the first threaded column 47 so that the first threaded column 47 is separated from the slide bar 42. At this time, the first sliding sleeve 43 loses the block, and the staff can lift and lower the moxibustion mold 46 to the specified position through the first sliding sleeve 43, the cross bar 44 and the second sliding sleeve 45. Then, the first threaded column 47 is rotated back until the first threaded column 47 abuts against the slide bar 42;

[0039] In summary, the experimenter can adjust the spatial position of the moxibustion mold 46 according to the different volumes of the rats, without having to customize the molds with corresponding structures according to the volumes of the rats, which effectively reduces the experimental burden on the experimenter. At the same time, the overall rat experiment fixing device can also be applicable to rats of different volumes, thereby expanding the practicality of the rat experiment fixing device.

[0040] In addition, it should be understood that although this specification is described according to the embodiments, not every 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.
