Description

Technical Field

[0001] The utility model belongs to the technical field of mouse tongue image collection, and particularly relates to an experimental mouse tongue image collection operation and fixing device. Background Art

[0002] In biomedical research, mice play an indispensable role as model organisms because mice and humans share approximately 90% homology in their genes and there are many genetic strains. Disease research can be well replicated in mice. At the same time, mice have low breeding costs and easy breeding conditions. They are widely used in many fields such as disease mechanisms, drug development, and genetic research.

[0003] Tongue diagnosis in traditional Chinese medicine belongs to the category of visual diagnosis. The changes in tongue images can be used as an important basis for diagnosing diseases and differentiating syndromes. By using experimental mice to compare and evaluate tongue images and symptoms, it plays an extremely important role in assisting syndrome diagnosis and exploring the molecular mechanism of diseases. At present, when taking tongue images of mice, it requires the collaboration of multiple people, some to hold the mice, some to open their mouths with tools, and some to shoot with cameras. This is time-consuming and laborious, and the results of data collection are easily affected by human factors, which increases the workload of the experimenters. Utility Model Content

[0028] The two sides of the lower part of the upper body support plate 3 are horizontally and symmetrically fixed with shaft rods 20, and a first slotted hole 21 is opened on the side wall of the operating platform 1 on one side of the groove 2, and a limiting ring 22 corresponding to the position of the first slotted hole 21 is fixedly set on the side wall of the operating platform 1 on the other side of the groove 2, which can block the upper body support plate 3 and prevent the upper body support plate 3 from escaping from the groove 2. One end of the shaft rod 20 is arranged in the first slotted hole 21, and the other end of the shaft rod 20 passes through the center hole of the limiting ring 22 and is vertically fixedly connected to the center of the first gear 23, which can not only ensure the reliable connection between the upper body support plate 3 and the operating platform 1, but also enable the upper body support plate 3 to flip along the shaft rod 20. A connected through hole 24 and a second slotted hole 25 are horizontally opened on the side wall of the operating platform 1 near the limiting ring 22, and a ball head 26 is arranged in the second slotted hole 25. The ball head 26 has the same shape and size as the second slotted hole 25, which ensures the smooth rotation of the ball head 26 in the second slotted hole 25 and reduces friction. The diameter of the head 26 is larger than the aperture of the through hole 24 to prevent the ball head 26 from being separated from the second slot 25.

When the second gear 29 rotates one circle, the first gear 23 rotates a quarter circle, which is convenient for adjusting the flip angle of the upper body support plate 3 so that it is turned to an angle suitable for operating the experimental mice.

[0029] A third slot 46 is provided on the operating platform 1 at one end of the second slot 25 away from the through hole 24. The cross section of the third slot 46 is a regular octagon, which is convenient for blocking the plug rod 47 to prevent the plug rod 47 in the third slot 46 from rotating. The end of the ball head 26 away from the rotating rod 27 is fixedly provided with a plug rod 47. The plug rod 47 corresponds to the position of the third slot 46 and the size is matched. The cross section of the plug rod 47 is also a regular octagon, which ensures that the plug rod 47 is reliably connected to the operating platform 1 after being inserted into the third slot 46. The depth of the second slot 25 is greater than that of the ball head 26. The sum of the diameter of the head 26 and the length of the insertion rod 47 ensures that when the ball head 26 is pulled to the through hole 24, the insertion rod 47 disengages from the third slot 46. The thickness of the second gear 29 is greater than the thickness of the first gear 23 to avoid the first gear 23 and the second gear 29 being separated when the rotating rod 27 is pulled. When the knob 28 needs to be turned, the rotating rod 27 is pulled outward and the insertion rod 47 disengages from the third slot 46. When the upper body support plate 3 is flipped to an appropriate angle, the rotating rod 27 is pushed inward to insert the insertion rod 47 into the third slot 46 to ensure the stable and reliable position of the upper body support plate 3.

When the operator opens the mouth opener 11 with fingers, the upper and lower incisors of the mouse are fixed through the tooth holes 36, thereby opening and fixing the upper and lower jaws of the mouse, providing a good field of view for collecting the tongue image of the mouse.

[0031] The operating platform 1 is provided with an opener placement rack 37, a natural light collector 38 and a fill light 39. The opener 11 is placed through the opener placement rack 37. The upper end of the opener placement rack 37 has a slot for placing the front end support rod 15 of the opener 11. When there is sufficient natural light in the experimental site, the natural light collector 38 can be rotated to make the natural light reflected by the natural light collector 38 hit the mouse head. When natural light cannot meet the collection requirements, the fill light 39 can be used for fill light. The support arm of the fill light 39 can be movable, and the irradiation angle of the fill light 39 can be adjusted according to the position of the mouse head. The operating platform 1 is provided with three second slide grooves 40, and the lower ends of the opener placement frame 37, the natural light collector 38 and the fill light 39 are fixedly provided with a bottom block 41, and the middle position of the lower end of the bottom block 41 is fixedly provided with a slider 42, and the slider 42 is arranged in the second slide groove 40, and the lower end of the slider 42 is threadedly connected with a bolt fixing knob 43, and the slider 42 moves in the second slide groove 40, thereby making the opener placement frame 37, the natural light collector 38 and the fill light 39 move along the second slide groove 40, and the outer diameters of the bottom block 41 and the bolt fixing knob 43 are larger than the width of the second slide groove 40, so as to prevent the opener placement frame 37, the natural light collector 38 and the fill light 39 from detaching from the operating platform 1.
