[0002] Moxibustion is a traditional external treatment method in Traditional Chinese Medicine (TCM). Its core principle is to use moxa sticks made from mugwort leaves, generating a photothermal effect when burned, to target specific acupuncture points or areas on the body surface for therapeutic and health-improving purposes. Moxibustion, due to its excellent performance in disease prevention and treatment, is widely used in folk and modern TCM clinical practice.

DETAILED DESCRIPTION

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] like Figure 1-8 The intelligent device for temperature-controlled moxibustion of the limbs of experimental animals shown in the figure includes a base 3, on which is provided an acquisition control system, which includes a control module, an acquisition module and a display module. The control module can clamp the moxa stick and control its lifting position; the acquisition module includes a monitor 22 with body temperature monitoring and pulse monitoring functions; the display module includes a computer display interface, which can display the body temperature monitoring information and pulse monitoring information collected by the acquisition module.

[0020] A plurality of limb fixing plates 14 are installed on the top of the base 3, and auxiliary slide rails 6 are installed through both ends of the limb fixing plates 14. Both ends of the two auxiliary slide rails 6 are slidably connected with auxiliary sliders 16. Since the limbs of mice are of different lengths, in order to facilitate the limb fixing buckles 18 to fix mice with different limb lengths, the auxiliary sliders 16 slide on the auxiliary slide rails 6, and the auxiliary sliders 16 adjust the size between the limb fixing buckles 18 and the limb fixing plates 14, so that the limb fixing buckles 18 can be adjusted to the position according to the different lengths of the mice's limbs.

[0021] A monitor 22 is embedded on the top of each of the four auxiliary sliders 16. An intelligent temperature sensing chip and a pulse sensing chip are installed in the monitor 22. The monitor 2 is electrically connected to the display module via a data line. The intelligent temperature sensing chip is in direct contact with the limbs of the experimental animal. The temperature signal is fed back to the controller. The controller transmits the signal to the display screen of the PC through a data line or a wireless module and displays it on the computer display interface, making it convenient to view the real-time data of the mice during the experiment.

[0022] The surfaces of the four sub-sliders 16 are connected with limb fixing buckles 18, which are used to fix the limbs of the mouse. One end of the limb fixing buckle 18 is movably connected to one end of the sub-slide 16 through a pin, and the other end of the limb fixing buckle 18 is connected to the other end of the sub-slide 16 through a stud. When fixing the limbs of the mouse, it is only necessary to insert the mouse's limbs deep between the limb fixing buckle 18 and the sub-slide 16, and then thread the stud between the other end of the limb fixing buckle 18 and the other end of the sub-slide 16. The limb fixing buckle 18 is pressed on the top of the mouse's limbs, and the bottom of the mouse's limbs is pressed on the top of the sub-slide 16 to fix the mouse's limbs.

[0023] Electric clamps 2 capable of clamping moxa sticks are provided above the four auxiliary sliders 16 , and the movable ends of the electric clamps 2 clamp the moxa sticks 13 to fix the position of the moxa sticks 13 .

[0024] The outer shells of the four electric clamps 2 are all connected to the movable end of the lifting motor 1. As the moxa stick 13 burns, the length of the moxa stick 13 becomes shorter and shorter. Therefore, the temperature of the mouse limbs gradually decreases during the moxibustion of the mouse limbs by the moxa stick 13 through the flue gas. The monitor 22 feeds back the collected temperature information to the PID controller. The PID controller compares the transmitted data with the preset temperature data, and controls the movable end of the lifting motor 1 to drive the electric clamp 2 to move downward, so that the burning end of the moxa stick 13 is always in a preset position close to the mouse limbs; the lifting motor 1 is connected by a drive motor, a ball screw, a sliding block and a mounting concave part. The two ends of the ball screw are installed in the concave part through bearings. The PID controller controls the rotation of the movable end of the lifting motor 1, and the drive motor controls the rotation of the ball screw. The movable end on the ball screw drives the sliding block to move, and the sliding block drives the electric clamp 2 to move.

[0025] The lifting motor 1 and the base 3 are movably connected. Two main slide rails 4 are installed on the top of the base 3. The two main slide rails 4 are symmetrically distributed on both sides of the base 3. Main sliders 5 are installed at the bottom ends of multiple lifting motors 1. Multiple main sliders 5 are respectively slidably installed on the surfaces of the two main slide rails 4. The main sliders 5 slide on the surfaces of the main slide rails 4, which facilitates the synchronous movement of the lifting motor 1 and is used to drive the moxa stick 13 to be adjusted horizontally through the electric clamp 2, so as to facilitate the control of the moxa stick 13 to move to the appropriate position in the horizontal direction.

[0026] One end of the limb fixing plate 14 is provided with a mouse neck positioning mechanism. The mouse neck positioning mechanism includes a mounting frame 8, the bottom of the mounting frame 8 is placed on the top of the limb fixing plate 14, and a fixing block 19 is installed at one end of the limb fixing plate 14. Two first screw holes are provided on the side of the fixing block 19, and position adjustment screws 21 are threadedly inserted into the interior of the two first screw holes. One end of the two position adjustment screws 21 is embedded in the bottom end of the mounting frame 8 through a bearing. Two symmetrically arranged limit rods 11 are provided inside the mounting frame 8, and the upper part 10 of the neck fixer and the lower part 12 of the neck fixer are respectively sleeved between the two limit rods 11 from top to bottom. A second screw hole is provided at the top of the mounting frame 8, and a neck adjustment screw 9 is threadedly inserted into the interior of the second screw hole, and one end of the neck adjustment screw 9 is against the top of the upper part 10 of the neck fixer. The upper part 10 of the neck fixator and the lower part 12 of the neck fixator are both arc-shaped. In order to facilitate the upper part 10 and the lower part 12 of the neck fixator to fit the neck of the mouse, the stability of the upper part 10 and the lower part 12 of the neck fixator in fixing the mouse's neck is increased; when fixing the mouse's neck, first pass the mouse's head through the space between the upper part 10 and the lower part 12 of the neck fixator, place the mouse's neck in the lower part 12 of the neck fixator, and then turn the neck adjusting screw 9. While the neck adjusting screw 9 is spirally rotated, it pushes the upper part 10 of the neck fixator downward, and the upper part 10 of the neck fixator moves to the top of the mouse's neck. The height of the neck adjusting screw 9 is appropriately adjusted to ensure that the mouse's neck is fixed while protecting the mouse's neck.

[0027] The ash tray 7 with a filter is provided above both ends of the two auxiliary slide rails 6. Support rods 17 are connected between the four corners of the bottom of the four ash trays 7 and the two ends of the two auxiliary slide rails 6. The positions of the ash tray 7 and the electric clamp 2 correspond vertically. The movable end of the electric clamp 2 clamps the moxa stick 13. The ash produced after the moxa stick 13 burns falls on the filter on the top of the ash tray 7, preventing the high temperature remaining in the ash from scalding the experimental mice and preventing the mice from struggling due to high temperature burns. The medicinal moxa smoke can pass through the filter and act on the mouse body, ensuring the stability of the mouse during the moxibustion experiment; the support rod 17 is set to support the ash tray 7, and the space between the ash tray 7 and the auxiliary slide rail 6 can be used for the installation of the limb fixing buckle 18 and circular motion at a certain angle, which facilitates the placement of the mouse limbs in the space between the ash tray 7 and the auxiliary slide rail 6 and fixation through the limb fixing buckle 18. It should be noted that the dust collecting tray 7 with the filter installed is detachably mounted on the support rod 17, so that it can be disassembled and cleaned in a timely and convenient manner after use.

[0028] A through cavity 15 is provided on the side of the limb fixing plate 14 , and the two auxiliary slide rails 6 are inserted into the cavity. The two auxiliary slide rails 6 are fixedly installed at both ends of the cavity 15 , which facilitates the installation operation of the two auxiliary slide rails 6 .

[0029] The two symmetrical sides of the limb fixation plate 14 are provided with corresponding trunk fixing mechanisms, which include a mounting rod 24, one end of which is mounted on the side of the limb fixation plate 14, and the top of the mounting rod 24 extends to the top of the limb fixation plate 14. A third screw hole is provided at the top of the mounting rod 24, and a trunk positioning screw 23 is inserted into the internal thread of the third screw hole. One end of the trunk positioning screw 23 is mounted with a trunk fixing part 20 through a bearing. Two sliding rods 25 are installed on the top of the mounting rod 24. The two sliding rods 25 are distributed on both sides of the body positioning screw 23. One end of the two sliding rods 25 is installed on the outer arc surface of the body fixing piece 20. The two body fixing pieces 20 are both arc-shaped, and a silicone pad is adhered along the inner arc surface of the body fixing piece 20. When fixing the mouse's body, the two body positioning screws 23 are rotated in sequence, and the body positioning screws 23 spirally rotate in the third screw hole. One end of the body positioning screw 23 pushes the body fixing piece 20 to move, so that the body fixing piece 20 moves toward the mouse's body. When the two body fixing pieces 20 are moved to the surface of the mouse's body, the two body positioning screws 23 are slightly rotated to fix the mouse's body position and protect the mouse at the same time; the setting of the silicone pad increases the comfort of contact between the mouse and the body fixing piece 20; the setting of the two sliding rods 25 improves the stability of the body fixing piece 20 during horizontal movement.

[0030] In this solution, the monitor 22 is also provided with a pulse monitoring sensor, which is a small animal pulse oximeter, which is convenient for detecting the blood oxygen saturation, pulse rate, respiratory rate, pulse amplitude and respiratory amplitude of mice during the moxibustion experiment, and is convenient for providing mice with more monitoring data in the moxibustion experiment, which is convenient for the reference of the staff. The small animal pulse oximeter is connected to the PID controller through a wire.

[0031] Working principle: When conducting moxibustion experiments on multiple mice, the multiple mice are first placed on multiple limb fixing plates 14 in turn, and the mouse's head is first passed through the mounting frame 8, and then the neck adjusting screw 9 is rotated. The neck adjusting screw 9 pushes the upper part 10 of the neck fixer to press on the top of the mouse's neck, and the bottom of the mouse's neck is pressed on the lower part 12 of the neck fixer to fix the position of the mouse's neck; then the mouse's limbs are passed through the four limb fixing buckles 18 in turn, and the mouse's limbs are fixed by the limb fixing buckles 18; finally, the mouse's body is fixed. During operation, the two body positioning screws 23 are rotated in turn. The two body positioning screws 23 push the two body fixing parts 20 to clamp on the surface of the mouse's body during spiral motion to fix the mouse's body.

[0032] After the position of the mouse is fixed, multiple moxa sticks 13 are clamped and fixed in sequence by multiple electric clamps 2, and ignited from the bottom end of the moxa sticks 13, and the limbs of multiple mice are moxibustioned. During the moxibustion process, the temperature of the mouse limbs gradually changes. The monitor 22 detects the temperature of the mouse limbs and feeds the signal back to the controller through the wireless module. The controller sends the collected signal to the computer, and the computer displays the signal data on the display screen, which is convenient for the staff to check the temperature of multiple mouse limbs; As the moxa stick 13 burns, the length of the moxa stick 13 becomes shorter and shorter. Therefore, the temperature of the mouse's limbs gradually decreases during the moxibustion of the mouse's limbs by the moxa stick 13 through the smoke. The monitor 22 feeds back the information to the PID controller, and the PID controller controls the movable end of the lifting motor 1 to drive the electric clamp 2 to move downward, so that the burning end of the moxa stick 13 is always in a position close to the mouse's limbs, which facilitates the completion of the mouse limb moxibustion experimental operation.
