Description

Technical Field

[0001] This utility model relates to medical teaching experiments, and more particularly to a fixed anesthesia cage for teaching experimental animals. Background Technology

[0002] Rabbits are commonly used laboratory animals in medical experiments. The rabbit anesthesia box is an indispensable tool in medical experiments, primarily used to immobilize rabbits during procedures such as intravenous injections via the ear vein, intravenous infusions, anesthesia, and blood sampling. In school teaching, the rabbit anesthesia box is also a necessary item.

[0003] Currently, traditional experimental anesthesia rabbit boxes have the following problems: 1. When fixing the rabbit's head, the traditional rabbit box's "guillotine" design can easily cause novice operators to lose control of their strength, compressing the rabbit's neck and leading to suffocation and death, thus affecting the experimental process. 2. Although traditional rabbit boxes are available in different sizes, the large individual differences among rabbits mean they cannot meet the personalized needs of fixing rabbits of various sizes. During operation, rabbits are often difficult to insert due to improper size, or their legs may kick out from behind, injuring the experimenter. 3. Traditional rabbit boxes expose the rabbit's entire head. When inserting the needle, the rabbit experiences pain stress, causing its head to sway from side to side, which in turn causes the ears to move, and the rabbit box cannot effectively fix the head. This often leads to novice operators' needles slipping out of the blood vessel or piercing the rabbit's ear, wasting a lot of experimental time. Summary of the Invention

[0017] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0018] Please refer to the reference. Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present invention provides a fixed anesthesia cage for teaching experimental animals, comprising a first box 100, a second box 200, and a head fixing device 300. The first box 100 has an opening on its upper side. A slide rail 410 is fixed on the front and rear sides of one end of the first box 100. A corresponding slider 420 is provided on the front and rear sides of one end of the second box 200 facing the first box 100. A fastening bolt 430 is provided on the slide rail 410. The first box 100 and the second box 200 are connected by the slide rail 410 and the slider 420. The slide rail 410 and the slider 420 are locked by the fastening bolt 430. This ensures that the first box 100 and the second box 200 are fixed together. The distance between the first box 100 and the second box 200 can be adjusted by sliding connection.

[0019] The first box 100 has a first through hole 101 on the side facing the second box 200, and the second box 200 has an open end on the side facing the first box 100. The first through hole 101 is larger than the size of the rabbit head, ensuring that when in use, the rabbit head is passed through the first through hole 101 and positioned facing the second box 200. When the second box 200 is fixed, the rabbit head is placed inside the second box 200, avoiding the head being exposed during puncture and causing the rabbit to experience pain and stress during needle insertion.

[0020] The head fixing device 300 is composed of clamping parts symmetrically arranged on both sides of the first through hole 101; the clamping part includes an elastic connecting piece 310, a fixing block 320 and a locking adjustment block 330; the elastic connecting piece 310 is a metal spring sheet, one end of the elastic connecting piece 310 is fixed to the first box 100, the other end of the elastic connecting piece 310 is connected to the fixing block 320, one end of the locking adjustment block 330 is fixed to the first box 100, the locking adjustment block 330 is arranged on the outside of the elastic connecting piece 310, and the locking adjustment block 330 is provided with a through threaded hole 331, and a locking bolt 340 is connected to the threaded hole 331 by thread. In use, the rabbit's head is positioned between the two clamping parts. The locking bolts 340 on both sides are rotated, pushing the fixing block 320 inward to clamp the rabbit's or other animal's cheeks, thus securing the rabbit's head. This invention, by fixing the rabbit's cheeks, avoids the suffocation and death caused by the traditional rabbit box pressing on the rabbit's neck, ensuring the experiment can proceed normally. Simultaneously, fixing the rabbit's cheeks also prevents stress and head swaying, ensuring effective head fixation, effective ear puncture, and reducing wasted experimental time.

[0021] In use, firstly, place the experimental rabbit or animal into the first box 100 through the upper side opening, with its head protruding through the first through hole 101, positioned between the two clamping parts. Next, using the head fixing device 300, tighten the locking bolt 340 to push the fixing block 320 inward, clamping the rabbit's or other animal's cheek to fix its head. Then, engage the slider 420 on the second box 200 with the slide rail 410, sliding the second box 200 closer to the first box 100, clamping the rabbit's ears between the opposite sides of the first box 100 and the second box 200. Finally, rotate the fastening bolt 430 to lock the slide rail 410 and the slider 420, fixing the first box 100 and the second box 200 in place. This ensures effective fixation of the rabbit's head during actual use, preventing the ears from wobbling and avoiding the risk of the needle slipping out of a blood vessel or puncturing the rabbit's ear.

[0022] Furthermore, the first box body 100 includes a front plate 110, a rear plate 120, and a telescopic frame 130; the telescopic frame 130 is a diamond-shaped telescopic frame formed by multiple connecting rods hinged together; a first hinge plate 111 is provided on the front plate 110, and a corresponding second hinge plate 121 is provided on the rear plate 120; the two ends of the telescopic frame 130 are respectively hinged and fixed to the first hinge plate 111 and the second hinge plate 121; the bottom of the front plate 110 is provided with an insert plate 112 extending towards the rear plate 120, and the bottom of the rear plate 120 is provided with a support plate 122 extending towards the front plate; the support plate 122 is provided with a corresponding insertion socket 123, and the insert plate 112 can slide within the insertion socket 123. The length of the first box 100 is adjustable to meet the individual needs of rabbits of various sizes. The length of the second box can be adjusted according to the size of the rabbit to ensure that the rabbit can be placed in the first box 100 during the operation. This avoids the rabbit being unable to fit due to an unsuitable size or its legs kicking out from behind and scratching the experimenter.

[0023] Furthermore, the side of the fixing block 320 away from the locking adjustment block 330 is an arc-shaped surface, and an elastic pad 321 is fixed to the arc-shaped surface. The elastic pad 321 can be made of rubber or sponge and can be fixed by adhesive or other means to ensure the comfort of the fixing block 320 when clamping the rabbit or animal's cheek, while increasing the friction between the fixing block 320 and the cheek to ensure a firm fixation and prevent slippage.

[0024] Furthermore, a first flexible protrusion 102 is provided above the first through hole 101. The first flexible protrusion 102 is horizontally arranged on the first box body 100. A side plate 210 is provided on the upper part of the side of the second box body 200 facing the first box body, and a corresponding second flexible protrusion 220 is provided on the side plate 210. The lower surface of the second box body 200 can also be made open, and the height of the second box body 200 is less than the height of the first box body 100. The bottom of the second box body is a certain distance from the table or test bench, etc., to ensure that the bottom of the second box body 200 is not rubbed by the plane when sliding and fixed, which facilitates installation and fixation, facilitates air circulation, and avoids discomfort caused by lack of oxygen in the closed space for rabbits or other test animals. When the rabbit ear is clamped between the first box body 100 and the second box body 200, the flexible protrusion makes flexible contact with the rabbit ear to avoid damage to the rabbit ear, improve the comfort and safety of rabbit ear clamping, and avoid stress response caused by hard contact when the rabbit ear is clamped.

[0025] Furthermore, the first flexible protrusion 102 and the second flexible protrusion 220 are made of rubber, and there is at least one of each. The first flexible protrusion 102 and the second flexible protrusion 220 can be fixed by adhesive bonding or groove embedding. This increases the surface friction between the flexible protrusion and the rabbit ear, ensuring stable and secure clamping of the rabbit ear. During actual operation, the rabbit ear will not swing, ensuring the normal conduct of the anesthesia experiment.

[0026] Furthermore, the length of the insert plate 112 is 10-50cm, and the length of the support plate 122 is the same as the length of the insert plate 112. This ensures that the length of the first box 100 is adjustable to meet the needs of rabbits or animals of different sizes, with an adjustment range of 10-100cm.

[0027] Furthermore, the slide rail 410 includes a body block 411 and a slide hole 412. One side of the body block 411 is fixed to the side of the front plate 110. The slide hole 412 passes through the left and right sides of the body block 411. The channel direction of the slide hole 412 is the same as the length direction of the first box 100. The side of the body block 411 away from the front plate 110 is provided with a first threaded hole 413. The first threaded hole 413 passes through the slide hole 412. The channel direction of the first threaded hole 413 and the slide hole 412 are perpendicular to each other. The fastening bolt is connected to the first threaded hole 413 by a thread. The slider 420 includes a slider body 422 and a fixing seat 421. The fixing seat 421 is fixed to the front and rear sides of the second box 200. The fixing seat 421 fixes one end of the slider body 422 to the side of the first box 100. The slider body 422 is inserted into the slide hole 412 and slidably engages with the slide hole 412. The slide rail 410 and the slider 420 are designed for easy use and are connected to the fastening bolt 430 through the first threaded hole 413. This allows the fastening bolt 430 to be easily tightened and loosened, making the slider body simple and convenient to use.

[0028] Furthermore, the slide hole 412 is a rectangular hole, and the slider body 422 is a strip-shaped block, with a correspondingly rectangular cross-section. This ensures that the contact surface of the locking bolt is flat, easy to lock, prevents slippage, and provides a firm and stable positioning.

[0029] Furthermore, both the fastening bolt 430 and the locking bolt 340 are wing bolts. The nut portion of the wing bolt has symmetrical wings, allowing for installation or removal by hand without tools, making it easy to operate and convenient for tightening and unlocking.

[0030] Furthermore, the first box body 100 is also provided with a second through hole 103, which is located below the first through hole 101. The second through hole 103 is a rectangular opening, and its lower side is flush with the inner bottom of the first box body 100. This allows the rabbit's legs to extend out through the second through hole 103, preventing the rabbit's legs from curling up and reducing its comfort. It also helps maintain the rabbit's or animal's lying posture, improving the rabbit's sense of security and comfort, preventing the rabbit from becoming agitated, and preventing the rabbit from standing up inside the first box body 100 and breaking free.
