Description

Technical Field

[0001] The utility model relates to the technical field of experimental rat fixation, in particular to an acupuncture and moxibustion fixation device for the lower limbs of experimental rats. Background Art

[0002] Acupuncture is a general term for both acupuncture and moxibustion. In Traditional Chinese Medicine, acupuncture or moxibustion is used to treat illnesses through the application of acupuncture points on the body. Acupuncture involves inserting needles (usually filiform needles) at specific angles, guided by TCM theory. The needles are then applied using techniques such as twisting and lifting to stimulate specific areas of the body, thereby treating illness. These insertion points are known as facial acupuncture points, or simply acupoints. Moxibustion involves burning and stimulating specific acupuncture points on the body using pre-prepared moxa sticks or moxibustion herbs, using the heat to prevent and treat illness. Mugwort is the most commonly used herb, hence the name moxibustion.

[0003] Basic scientific research on acupuncture requires the use of experimental animals and relevant disease models to explore the mechanisms of acupuncture effects and acupoint specificity. Currently, the most commonly used experimental animals include dogs, cats, rabbits, guinea pigs, rats, and mice. Rodents such as rats and mice share a high degree of genetic homology with humans, have strong reproductive capacity, a rapid growth and maturation cycle, and are small and easy to breed, making them the most commonly used animals in basic acupuncture research. In animal acupuncture experiments, precise acupoint positioning is essential for effective treatment. This precise positioning relies on a stable fixture, which not only requires sufficient exposure of the mouse's acupuncture site but also ensures that the mouse remains quiet during the treatment, as the acupuncture process takes time.

[0004] Unlike humans, rats are upright animals whose knees are straight when standing. Rats, on the other hand, are quadrupeds that need to support their entire body weight and propel their bodies forward with their hind legs. Therefore, rats' knees are bent backwards in daily situations. This knee structure allows them to better distribute their body weight, provide greater support and stability, and more effectively utilize force to accelerate and jump. However, this characteristic makes it difficult to expose the lower limb acupoints during fixed acupuncture in rats, especially those on the posterior part of the lower limbs, such as Weizhong (the midpoint of the popliteal fossa), Yanglingquan, and Housanli.

[0005] Today's rat fixators are suitable for exposing the rat's lower limbs for acupuncture. Most of the time, the rat's knee joint remains in its original flexion angle. The flexed knee joint makes the acupuncture points on the back of the leg basically unexposed, making acupuncture difficult. Even if the lower limb is pulled out for acupuncture, the rat's knee joint will flex again after relaxation, causing the needle to shift or fall off over time, making it even more difficult to target the acupuncture points. In addition, the exposed fixator makes the rat easily anxious in a bright environment, affecting the experiment. Summary of the Invention

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an acupuncture and moxibustion fixation device for the lower limbs of experimental rats.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An acupuncture fixation device for the lower limbs of an experimental rat comprises a breathable sleeve and a base plate. The experimental rat is placed in the breathable sleeve, and holes are provided on both sides of the lower end of the breathable sleeve for allowing the lower limbs of the experimental rat to pass through. The upper part of the base plate is provided with multiple pairs of spaced fixing belts, and the free ends of each pair of fixing belts are detachably connected to fix the upper body of the experimental rat. The lower part of the base plate is provided with four limiting columns, and a space for the lower limbs of the experimental rat to pass through is formed between two limiting columns on the same side.

[0009] Furthermore, the bottom plate is formed of PC material.

[0010] Furthermore, the free ends of each pair of fixing straps are connected by Velcro.

[0011] Furthermore, the distance between the two limiting posts in the upper row is greater than the distance between the two limiting posts in the lower row.

[0012] Furthermore, a plurality of connection holes arranged in a matrix are provided on both sides of the lower portion of the base plate, and the lower ends of the four limiting columns are detachably connected to the corresponding connection holes.

[0013] Furthermore, the lower end of the limiting column is connected to the connecting hole via a threaded connection.

[0014] Furthermore, the four limiting columns are all formed of rubber material, and a rope hole is provided at the upper end of each limiting column. The locking rope passes through the rope hole on each limiting column in sequence, and the locking rope is tightened according to the body size of the experimental rat.

[0015] The utility model adopts the above technical solution, which has the following beneficial effects:

[0016] 1. The fixation device of the utility model can fully expose the lower limbs of experimental rats, helping scientific research experiments to complete acupuncture on the lower limb acupoints, or perform other operations such as knee joint surgery;

[0017] 2. The fixation device of the utility model does not use the closed fixation of the traditional PC material fixator, but is different from the exposed type. The rat is wrapped in socks, which makes the rat quieter and does not affect the treatment process.

[0018] 3. The position of the limiting column for fixing the lower limbs of the experimental rat on the chassis can be flexibly adjusted. At the same time, the limiting column is made of rubber material and combined with the tightening effect of the locking rope, the limiting column can be changed into an arc shape according to the body shape of the experimental rat, thereby better fitting the curvature of the rat's body and fixing it more firmly. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0020] Figure 1 This is a top view of the fixing device of the utility model;

[0021] Figure 2 This is a schematic diagram of an embodiment of the preferred structure of the bottom plate of the utility model;

[0022] Figure 3 This is a schematic diagram of the utility model for fixing experimental rats. DETAILED DESCRIPTION

[0023] like Figure 1-3 As shown, the present invention provides an acupuncture fixation device for the lower limbs of experimental rats, comprising a breathable cover 1 and a base plate 2. The experimental rat is placed within the breathable cover 1, and holes are provided on both sides of the lower end of the cover 1 for the rat's lower limbs to pass through. The breathable cover 1 provides a relatively stable position for the experimental rat, and the cover allows for ventilation, preventing suffocation. Furthermore, the breathable cover 1 can be made of everyday socks, making it convenient to obtain.

[0024] The base plate 2 is formed from PC. Multiple pairs of spaced-apart fixing straps 3 are provided on the upper portion of the base plate 2. An appropriate number of fixing straps 4 are selected based on the size of the experimental rat to secure the rat. One end of each pair of fixing straps 3 is fixed to the base plate 2 by screws, and the other free end of each pair of fixing straps 3 is detachably connected to secure the upper body of the experimental rat. The free ends of each pair of fixing straps 3 are connected via Velcro, with the inner surface of one fixing strap 3 being a Velcro sub-surface and the outer surface of the other fixing strap 3 being a Velcro main surface. This design allows the fixing straps 3 to adapt to different sizes of experimental rats and stably secure their upper bodies.

[0025] Four limiting posts 4 are provided at the bottom of the base plate 2. Two limiting posts 4 on the same side form a space for the rat's lower limbs to pass through. The distance between the two limiting posts 4 in the upper row is greater than that between the two limiting posts 4 in the lower row. This design allows for a better fit around the rat's thigh. The four limiting posts 4 above and below also help the rat extend its knee joint, effectively exposing the rat's lower limb acupuncture points.

[0026] The four limiting columns 4 are all made of rubber material, and the upper end of each limiting column 4 is provided with a rope hole. The locking rope 5 passes through the rope holes on each limiting column 4 in sequence, and the locking rope 5 is tightened according to the body shape of the experimental rat, so that the four limiting columns 4 are bent to fit the body curvature of the experimental rat, making the experimental rat more stably fixed.

[0027] Preferably, Figure 2As shown, a plurality of connection holes 6 can be designed on both sides of the lower portion of the base plate 2 in a matrix arrangement. The lower ends of the four retaining posts 4 are removably connected (threaded) to corresponding connection holes 6. The four retaining posts 4 are inserted into and locked into the connection holes 6 at appropriate locations according to the size of the experimental rat, thereby better fitting the rat's body. Of course, the retaining posts 4 can also be designed as a track-type structure, with the retaining posts 4 locked when they are moved to a position around the rat's legs, thereby better fitting the rat's body.

[0028] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
