DETAILED DESCRIPTION

[0030] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.

[0031] Moxibustion is one of the mainstream therapies in traditional Chinese medicine. Before clinical research and application, a large number of animal experiments must be conducted. Animal experiments are an important part of modern science and technology, and are the basis and important supporting conditions for the research of life sciences. Animal moxibustion experiments require animals to be fixed. Currently, related experiments often use mice as research subjects.

[0032] At present, the rat moxibustion experiment includes an experimental table, a support rod set on one side of the experimental table, and a long tail clip is set on the support rod. During moxibustion, the long tail clip is used to clamp the moxa stick and hang it on a homemade frame.

[0033] In current experiments on moxibustion on rats, the moxa sticks gradually become shorter as they burn, or the rats struggle and can easily cause the moxa sticks to deviate from the target acupuncture points, which often affects the transfer of heat from the moxa sticks and the release of medicinal effects, thus resulting in failure to achieve the expected moxibustion experimental results.

[0034] The present invention discloses an auxiliary fixing device for rodent experiments, such as Figure 1-Figure 5As shown, it includes a body 1 and a moxa stick fixing structure; wherein the body includes a box body 1 and a loading board 2 horizontally arranged in the box body 1, a rodent fixing structure is arranged on the loading board 2, and the experimental mouse is fixed on the loading board 2 by the rodent fixing structure, and the loading board 2 is long and adopts a perforated board; the moxa stick fixing structure includes a first slide rail 4, a telescopic bracket 5, a fixing block 8 and a moxa stick fixing needle 7, the first slide rail 4 is arranged on the loading board 2, the lower end of the telescopic bracket 5 is slidably connected with the first slide rail 4, the upper end of the telescopic bracket 5 is provided with the fixing block 8, and the moxa stick fixing needle 7 is arranged on the fixing block 8 and faces the experimental mouse. The telescopic bracket 5 includes a first connecting rod connected to the first slide rail 4, and the end of the first connecting rod away from the first slide rail 4 is also hinged with a second connecting rod, and the fixing block 8 is connected to the second connecting rod. The height of the telescopic bracket 5 can be adjusted by adjusting the angle between the first connecting rod and the second connecting rod.

[0035] Therefore, when the auxiliary fixing device for rat experiments disclosed in the present invention is used, the rat is fixed by the rat fixing structure, and then the moxa stick fixing needle 7 is inserted into the tail end of the moxa stick. During moxibustion, the telescopic bracket 5 can slide along the length direction of the straight track 4, and when the length of the moxa stick becomes shorter, the height of the moxa stick can be adjusted by the telescopic bracket 5. Therefore, during moxibustion, the auxiliary fixing device for rat experiments disclosed in the present invention drives the telescopic bracket 5 to slide along the first track 4, or adjusts the telescopic bracket 5 so that the moxa stick on the fixing needle 7 can be aimed at the target acupuncture point at any time, thereby ensuring the expected experimental effect.

[0036] In order to ensure the moxibustion effect when the mouse is not fixed well and struggles to move in the width direction, a swing motor 6 is also provided at the upper end of the telescopic bracket 5 disclosed in the present embodiment. The output shaft of the swing motor 6 is vertically upward, and the fixed block 8 is connected to the output shaft of the swing motor 6, and cooperates with the swing motor 6 to drive the fixed block 8 to rotate, which can drive the moxa stick fixing needle 7 set on the fixed block 8 to rotate a certain angle. Therefore, in this way, the position of the moxa stick is also rotated a certain angle, thereby effectively ensuring that the moxa stick is aligned with the moxibustion acupuncture point.

[0037] The moxa stick telescopic bracket 5 disclosed in this embodiment adopts a universal arm, which can perform moxibustion more flexibly.

[0038] In order to enable the telescopic bracket 5 to automatically slide along the first slide rail 4, a driving motor 38 is further provided in the fixing base 3 disclosed in the present embodiment, and the output shaft of the driving motor 38 is connected to the lower end of the telescopic bracket 5 through a belt transmission assembly. The specific belt transmission assembly includes a transmission belt 36 arranged on the inner side of the first slide rail 4, and pulleys 37 and a support shaft for supporting the rotation of the pulley 37 are respectively provided at both ends of the inner side of the transmission belt 36. A driving motor 38 is also provided in the fixing base 3, and a driving gear is provided on the output shaft of the driving motor 38, and a driven gear meshing with the driving gear is also provided on one of the support shafts, and the lower end of the telescopic bracket 5 is fixedly connected to the transmission belt 36; therefore, when the driving motor 38 is working, it drives the driving gear, the driven gear, the support shaft, the pulley and the transmission belt 36 to rotate in sequence, so that the telescopic bracket arranged on the driving belt 36 moves with the transmission belt, thereby realizing the automatic sliding of the telescopic bracket 5 along the first slide rail 4.

[0039] An ash hopper 9 is also provided on the fixed block 8, and the ash hopper 9 is located below the moxa stick fixing needle 7; the ash hopper can be installed on the telescopic bracket and below the front of the moxa stick burning section, and can collect the fallen moxa ash to prevent scalding the animal. A certain inclination angle is designed to make the moxa ash roll backwards to prevent the accumulation of moxa ash and affect the temperature of the moxa stick. There are several small holes in front of the ash hopper for the moxa stick to pass heat, so it can achieve the expected experimental effect.

[0040] like Figure 2 As shown, a hollow fixer base 3 is also provided on the loading plate 2, a first slide rail 4 is provided on the side of the fixer base 3, and a mouse fixing structure is also provided on the fixer base 3. The mouse fixing structure includes a head fixing unit, a trunk fixing unit and a tail fixing unit which are sequentially arranged along the length direction of the fixer base 3. Therefore, the mouse fixing structure disclosed in the present invention can fix the head, trunk and tail of the mouse respectively. When fixing, the mouse body is fixed first, and then the head and tail are fixed respectively.

[0041] like Figure 6As shown, the skull fixation unit includes a support plate 14, a support rod 15, a tooth fixing rod 16, a head fixing plate 17, a head clamping plate 36 and a connecting rod 18. The support plate 14 is vertically arranged at one end of the fixer base 3, the support rod 15 is horizontally arranged and one end thereof is rotatably connected to the support plate 14, the head fixing plate 17 and the tooth fixing rod 16 are respectively arranged in parallel on the upper and lower sides of the support rod 15, and the ends of the head fixing plate 17 and the tooth fixing rod 16 away from the support plate 14 extend beyond the support rod 15, and the end of the head fixing plate 17 away from the support plate 14 is also provided with a head clamping plate 36 facing the tooth fixing rod 16, and the head fixing plate 17, the support rod 15 and the tooth fixing rod 16 are connected by a connecting rod 18. Therefore, when fixing mice, the head of the mouse can be fixed by the head fixing unit; when fixing specifically, the head of the mouse is fixed by the head clamping plate 36 and the tooth fixing rod 16, the tooth fixing rod 16 is clamped at the mouse's teeth, and then the head is clamped by the head clamping plate, and because the support rod 15 is rotatably connected to the support plate 14, when the tooth fixing rod 16 is at the bottom and the head fixing plate 17 is at the top, the mouse is fixed in a prone position, and when the tooth fixing rod 16 is at the top and the head fixing plate 17 is at the bottom, the mouse is fixed in a supine position. According to different acupuncture point locations, a suitable body position is selected.

[0042] The trunk fixing unit includes a rope fixing pipe 19, a rope 20 and a rotating lock 21. The rope fixing pipe 19 is fixedly arranged inside the fixing base 3. After the rope 20 passes through the rope fixing pipe 19, both ends of the rope 20 pass through the fixing base 3, and the ends of the rope 20 are connected by the rotating lock 21. When fixing the body, the rotating lock 21 is used to fix the rope to fix the mouse. The fixing structure composed of the pipe 19, the rope 20 and the rotating lock 21 can be set in three groups, and the body of the mouse can be effectively fixed by three groups of ropes.

[0043] like Figure 7As shown, the tail fixing unit includes a second slide rail 22, a tail fixing slider 23, a tail fixing outer ring 24, a U-shaped steel 25 and an adjusting knob 26. The tail second slide rail 22 is arranged at the other end of the fixture base 3, and the tail second slide rail 22 is arranged along the length direction of the fixture base 3. The tail fixing slider 23 is slidably arranged on the tail second slide rail 22. The tail fixing outer ring 24 is fixed on the tail fixing slider 23. The upper side of the tail fixing outer ring 24 is provided with a mounting hole penetrating the inner side thereof. The adjusting knob 26 passes through the mounting hole and is threadedly connected to the mounting hole. The U-shaped steel 25 is connected to the lower end of the adjusting knob 26, and the opening of the U-shaped steel 25 faces the inner side of the tail fixing outer ring 24. When the mouse tail is fixed by the tail fixing unit, the tail fixing slider 23 can be moved on the second slide rail 22 to adjust it to suit mice of different sizes. Then, the mouse tail is placed between the tail fixing outer ring 24 and the U-shaped steel 25. The adjusting knob 26 is turned inward to make the U-shaped steel 25 move inward to shrink the space, and cooperate with the outer ring of the tail fixing outer ring 24 to clamp the mouse tail.

[0044] When the temperature of the moxa stick is too high, it will cause a stress reaction in the mice and cause them to struggle. Therefore, the moxibustion temperature should be kept within a reasonable temperature range. Therefore, the fixture base 3 disclosed in this embodiment is also provided with a temperature monitoring unit for monitoring the temperature of the acupuncture points of the experimental mice. The temperature monitoring unit includes a temperature sensor 10, an electronic display screen 11, a controller 12 and a cable 13. The electronic display screen 11 is arranged at one end of the fixture base 3, the controller 12 is arranged on the inner side of the fixture base 3, the temperature sensor 10 is arranged on the outer side of the fixture base 3 and is located around the moxibustion acupuncture points of the experimental mice. The temperature sensor 10 and the electronic display screen 11 are connected to the controller 12 through the cable 13. The controller 12 is connected, and the temperature at the acupoint detected by the temperature sensor 10 is displayed on the electronic display screen 11, which is convenient for the experimenter to adjust the height of the telescopic bracket 5. The cable 13 has a certain telescopic ability; when moxibustion is performed on mice, the temperature sensor 10 can be placed at the target acupoint first. The temperature sensor 10 is used to monitor the temperature change of the acupoint during moxibustion treatment in real time, and transmits data to the electronic display screen 11 through the retractable cable and displays the real-time temperature on the electronic screen 11, which is convenient for the experimenter to adjust the distance between the moxa stick and the acupoint at any time to ensure a safe distance, prevent the animal from being burned due to being too close or too far below the preset temperature, and fail to achieve a good experimental effect. At the same time, a temperature alarm program can be set in the controller 12, and an alarm will be issued in time when the temperature exceeds the preset temperature range to remind the experimenter; the temperature sensor electronic display screen button can be used to set the warning temperature.

[0045] Furthermore, excessive moxa smoke may irritate the respiratory tract of animals, causing discomfort or anxiety, thereby affecting their acceptance of moxibustion; when animals are nervous or uncomfortable, they may resist treatment and fail to achieve the expected experimental effect. Therefore, the top of the box body 1 disclosed in this embodiment is provided with a top cover structure with a semicircular cross-section, and the top cover structure includes a fixed cover body 28 fixed to the top of the box body 1. The cross-section of the fixed cover body 28 is fan-shaped. A sliding cover body 27 is also slidably provided on the fixed cover body 28. The fixed cover body 25 and the sliding cover body 27 both include a transparent outer top cover and an inner top cover, so as to observe the animals in the treatment chamber. A handle is provided on the outer transparent sliding cover body 27 to pull down the sliding cover body 27, and the rubber frame together with the inner fixed cover body 28 forms a closed transparent top cover that plays a sealing role, thereby preventing moxa smoke from overflowing the treatment chamber. The closing effect is shown in Figure 8. The sliding cover body 27 is also provided with an air inlet hole, and the size of the air inlet hole can be adjusted as needed, such as Fig. 9 As shown, when the moxa smoke is inhaled, a sufficient amount of fresh air is ensured to enter without affecting the breathing of the animals.

[0046] A smoke removal unit is also provided in the box 1, and the smoke removal unit includes a smoking pipe 29, an exhaust fan 30 and a hose 31. The exhaust fan 29 is provided at the bottom of the carrier plate 2. A plurality of smoking ports for fixing the smoking pipe are provided on both sides of the carrier plate 2. The smoking pipe 29 is provided through the smoking port. One end of the smoking pipe 29 is located on the upper side of the carrier plate 2, and the other end is located on the lower side of the carrier plate 2. The lower ends of the plurality of smoking pipes 29 are all connected to one end of the hose 31. The other end of the hose 31 is connected to the outside after passing through the smoke outlet provided on the outer wall of the box 1. A three-way catalytic converter 33 is also connected to the hose. An air inlet 32 ​​is also provided on the sliding cover 27. Therefore, the exhaust fan 30 is turned on to generate suction, and the moxa smoke is sucked out of the closable transparent top cover through the smoking pipe 29, and fresh air is sucked in from the air inlet 32 ​​with the help of suction to ensure the breathing of the animal. The moxa smoke sucked out from the mouth is discharged through the hose 31, which also helps to achieve the expected experimental effect.

[0047] A sandbox 34 is also provided on one side of the loading plate 2 for storing moxa sticks to prevent fire and ensure safety.

[0048] A storage bin 35 is provided at the bottom of the loading plate 2, and the internal structure of the storage bin 35 is shown.
