Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments and equipment, and particularly relates to a rat head and limb fixing device for acupuncture of rats. Background Art

[0002] Rats are animals that are frequently used in experiments on the mechanism of acupuncture. Common methods of fixation of rats include binding fixation, instrument fixation, and hand grasping fixation. At present, the commonly used method of fixation of rats for acupuncture is restraint fixation, including fixation in a small space and binding fixation. However, restraint fixation can cause restraint stress effect in rats, which is superimposed on the acupuncture effect and seriously interferes with the objective analysis of the acupuncture effect. Therefore, how to choose an appropriate rat fixation method during acupuncture to minimize the interference of stress effect on acupuncture effect is a key issue faced in acupuncture research.

[0003] For example, the Chinese utility model patent with patent number CN201620043881.X discloses a rat acupuncture fixator, including a chassis, two brackets, a body fixing tube, a hind limb fixing fork, a forelimb fixing fork and two neck fixing rods. The two brackets are fixed on the chassis in parallel with each other, and the body fixing tube is placed horizontally on the two brackets. The body fixing tube is a mesh cylindrical shape. When the rat is placed in the body fixing tube and the rat's limbs extend from the mesh of the body fixing tube, the hind limb fixing fork passes through the tail of the body fixing tube from top to bottom and the plane where the hind limb fixing fork is located intersects with the axis of the body fixing tube, the forelimb fixing fork passes through the body fixing tube vertically downward and the plane where the forelimb fixing fork is located is parallel to the axis of the body fixing tube, and the two neck fixing rods cross and pass through the body fixing tube along the cross-sectional direction of the body fixing tube, and the intersection is in the body fixing tube, so that the head of the rat is fixed by the cooperation of the body fixing tube and the neck fixing rod. In this way, any part of the rat can be acupunctured, and the rat can be prevented from struggling during the acupuncture process, thereby facilitating the acupuncture operation.

[0004] However, the device has the problem that it takes advantage of the fact that rats like to burrow holes. When the rats burrow into the body fixing tube and stop moving, the rats' limbs will naturally curl up or semi-curl up. When the rats' limbs are fixed using the hind limb fixing forks, forelimb fixing forks and two neck fixing rods, the rats' limbs are simply fixed, and the rats' limbs cannot be changed from a curled up state to a naturally extended state. The acupuncture site is mainly the abdomen of the rats, resulting in a small acupuncture range for the abdomen of rats in a curled up state and the existence of a blind spot for acupuncture.

[0029] Please see Figures 1 to 5A rat head and limb fixing device for rat acupuncture includes an arch tube 10, a rat back fixing piece 20, a rat head fixing piece 30 and a limb fixing piece 40. A screen 111 is arranged on the plane of the arch tube 10. The rat back fixing piece 20 and the rat head fixing piece 30 are arranged on the curved surface of the arch tube 10 and can move up and down in the vertical direction. The limb fixing piece 40 is arranged at both ends of the arch tube 10. Taking advantage of the characteristic of rats that they like to burrow holes, after catching a rat, the rat is placed at the entrance of the arch tube 10, and the rat will burrow into the arch tube 10. When all the limbs of the rat enter the arch tube 10, the back of the rat corresponds to the curved surface of the arch tube 10, and the abdomen of the rat corresponds to the plane of the arch tube 10. At this time, the rat back fixing member 20 and the rat head fixing member 30 are moved downward, and the rat back fixing member 20 presses the back of the rat, so that the abdomen of the rat and the screen 111 of the arch tube 10 fit each other to prevent the abdomen of the rat from curling up. The rat head fixing member 30 fixes the rat's head in the arch tube 10 to prevent the rat's head from swinging left and right. At this time, the limbs of the rat are exposed outside the arch tube 10, and the limb fixing member 40 is used to tie the limbs of the rat and stretch them so that the limbs and abdomen of the rat are in a naturally stretched state, and the arch tube 10 is changed from a horizontal state to an upright state (see Figure 4 ), exposing the mesh 111. At this time, the mesh 111 can expose the abdomen of the rat and perform acupuncture.

[0030] Effect achieved: The device can fix the head and limbs of the rat, so that the limbs of the rat are in a naturally extended state, and acupuncture is performed on the abdomen of the rat. The acupuncture range is large and the blind spot of the acupuncture in the abdomen of the rat can be greatly reduced.

[0031] In one possible embodiment, see Figure 2 The arched tube 10 includes a flat plate 110 and an arc plate 120. Both ends of the flat plate 110 are connected to the limb fixing member 40. The screen 111 is arranged on the flat plate 110 and can slide parallel to the flat plate 110. When the abdomen of the rat is attached to the screen 111, when acupuncture is performed on the abdomen of the rat, since the screen 111 uses a screen 111 with a larger mesh number, most of the area of ​​the abdomen of the rat can be exposed. However, since the screen 111 itself blocks the abdomen of the rat, it has a blind spot for acupuncture. It is necessary to fine-tune the screen 111 to expose the blind spot for acupuncture, and a sandwich is provided in the flat plate 110, and the screen 111 is clamped in the sandwich. The screen 111 can slide parallel in the sandwich to achieve the effect of fine-tuning the screen 111. At the same time, it can also prevent rats from escaping. The arc plate 120 is provided on the flat plate 110, and the rat back fixing part 20 and the rat head fixing part 30 are provided on the arc plate 120. The arc plate 120 can be similar to the arc-shaped back of the rat, which is suitable for the characteristic that the rat likes to dig holes.

[0032] In one possible embodiment, see Figure 4 The flat plate 110 is detachably provided with a closing plate 112, and the closing plate 112 is fitted with the screen 111. Before acupuncture or when not in use, the closing plate 112 is fitted with the screen 111 to seal the arch tube 10 and prevent the screen 111 from rusting. When acupuncture is required for rats, the closing plate 112 is opened to expose the screen 111.

[0033] In a possible embodiment, the arch tube 10 further includes a dark cover 130, which can be rotatably disposed on the arc plate 120, and the dark cover 130 is disposed near the side of the rat head fixing member 30. The dark cover 130 is similar to the rat head, and the dark cover 130 is first partially opened. When the rat head is just exposed from the arc plate 120, the rat back fixing member 20 and the rat head fixing member 30 are used to fix the rat. After the fixation is completed, the dark cover 130 is rotated and buckled on the rat head, and the rat head is covered in the dark cover 130. Rats like darkness and can remain calm in a dark environment without violent shaking of the body. The main functions of the dark cover 130 are: (1) fix the rat head; (2) keep the rat calm.

[0034] In one possible embodiment, see Figure 3 The arcuate tube 10 is provided with a first threaded hole 121, see Figure 6 The rat back fixing member 20 includes a first threaded column 210, a curved plate 220 and a first rotating ring 230. The first threaded column 210 is sleeved in the first threaded hole 121. The curved plate 220 is arranged at one end of the first threaded column 210 and is located in the arched tube 10. The first rotating ring 230 is fixedly sleeved at the other end of the first threaded column 210. When the rat drills into the arched tube 10, the first rotating ring 230 is screwed to rotate the first threaded column 210 along the first threaded hole 121. The first threaded column 210 moves vertically downward, pushing the curved plate 220 to move vertically downward. The curved plate 220 is more likely to fit the back of the rat, and has the function of limiting and fixing, preventing the rat from shaking violently in the arched tube 10.

[0035] In one possible embodiment, see Figure 3 The arcuate tube 10 is provided with a second threaded hole 122, see Figure 7The rat head fixing member 30 includes a second threaded column 310, an L-shaped plate 320 and a second rotating ring 330. The second threaded column 310 is sleeved in the second threaded hole 122. The L-shaped plate 320 is arranged at one end of the second threaded column 310 and is located in the arch tube 10. The L-shaped plate 320 is provided with a bayonet 340. The second rotating ring 330 is fixedly sleeved at the other end of the second threaded column 310. When the rat drills into the arch tube 10, the second rotating ring 330 is screwed to rotate the second threaded column 310 along the second threaded hole 122. The second threaded column 310 moves vertically downward, pushing the L-shaped plate 320 to move vertically downward. The L-shaped plate 320 can fit the back of the rat and has a fixing effect. The bayonet 340 of the L-shaped plate 320 clamps the neck of the rat and has a limiting and fixing effect to prevent the rat's head from shaking in the arch tube 10.

[0036] In one possible embodiment, see Figure 3 The arch tube 10 is provided with a forelimb limiting opening 123 and a hindlimb limiting opening 124. The limb fixing part 40 includes a forelimb fixing part 410 and a hindlimb fixing part 420. The forelimb fixing part 410 is fixedly connected to one end of the arch tube 10, and the forelimb fixing part 410 is arranged on a side close to the rat head fixing part 30. The hindlimb fixing part 420 is fixedly connected to the other end of the arch tube 10, and the hindlimb fixing part 420 is arranged on a side close to the rat back fixing part 20. The forelimb limiting opening 123 and the hindlimb limiting opening 124 are arranged in a gourd-shaped shape, so that the forelimbs and hindlimbs of the rat can be buckled in the forelimb limiting opening 123 and the hindlimb limiting opening 124.

[0037] In one possible embodiment, see Figure 2 The forelimb fixing member 410 includes a first extension plate 411, a first tightening column 412 and a first binding rope 413. The first extension plate 411 is arranged at one end of the bow tube 10, and the first tightening column 412 is arranged at both ends of the first extension plate 411. The first tightening column 412 can rotate in one direction, and the first binding rope 413 is wound around the first tightening column 412. The first extension plate 411 can be freely retracted and driven to move the tightening column to a reserved position, which is a position that does not block the doctor from acupuncturing the abdomen of the rat. The first tightening column 412 rotates in one direction to tighten the first binding rope 413, such as a ratchet. When tightened to the maximum position, the first tightening column 412 stops rotating. At this time, the first tightening column 412 will stretch the forelimbs of the rat, driving the rat's limbs to be in a naturally stretched state. After the rat is acupunctured, the first tightening column 412 is retracted, such as opening the one-way valve of the ratchet to achieve reverse rotation, thereby making the first binding rope 413 in a relaxed state.

[0038] Specifically, one end of the first binding rope 413 is provided with a retractable ring, which can be used to bind the limbs of the rat, is easy to use, and is simple to unbind.

[0039] In a possible embodiment, the hind limb fixing member 420 includes a second extension plate 421, a second tightening column 422 and a second binding rope 423, wherein the second extension plate 421 is arranged at one end of the arch tube 10, the second tightening column 422 is arranged at both ends of the second extension plate 421, the second tightening column 422 can rotate in one direction, and the second binding rope 423 is wound around the second tightening column 422. The use steps of the hind limb fixing member 420 are the same as the use steps of the forelimb fixing, but the fixing function of the hind limb fixing member 420 is more important, because the forelimbs of the rat will enter the arch tube 10 first, and when the rat is small, the forelimbs of the rat are not easy to be pulled out from the forelimb limiting opening 123, and the rat head fixing member 30 can only be used to fix the rat head and forelimbs, but it is easy to pull the hind limbs of the rat, and the hind limbs of the rat are more likely to shake, therefore, stretching and fixing the hind limbs of the rat will greatly make the rat limbs naturally stretched, which is convenient for acupuncture.

[0040] In a possible embodiment, the rat head and limb fixation device for rat acupuncture further includes a support plate 50, and the support plate 50 is hinged to the limb fixation member 40. The support plate 50 is rotated to change the arched tube 10 from a horizontal state to an upright state, so that the doctor can directly see the abdomen of the rat, which is convenient for acupuncture.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
