Description

Technical Field

[0001] This utility model relates to the field of biomedical experimental equipment technology, and in particular to a fixator for visual ear vein injection in rabbits. Background Technology

[0002] Rabbit marginal ear vein injection is a technique that injects drugs or solutions into the body through a vein in the rabbit's ear. It is widely used in animal experiments in biomedical research and experimental teaching. Currently, when performing rabbit marginal ear vein injection, a restraint device is usually used to stabilize the rabbit's body to facilitate the location of the vein in the ear. However, existing restraint devices mainly focus on stabilizing the rabbit's body, while the ear needs to be manually opened with the experimenter's fingers to expose the injection area, and then the injection is performed with the other hand. This manual restraint method is not stable enough, and the experimenter's hand may gradually loosen due to fatigue, thus affecting the accuracy and safety of the injection.

[0003] To improve this situation, it is necessary to design a fixator for rabbit visual marginal vein injection that can effectively assist in fixing the ear area. This would not only securely fix the rabbit's body during marginal vein injection but also effectively maintain the ear in an open position, reducing operational errors caused by hand fatigue and improving the stability and efficiency of the injection process. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a fixator for rabbit visual ear vein injection that can effectively assist in fixing the ear area.

[0005] The technical solution is as follows: A fixator for visual ear vein injection in rabbits includes a placement frame, a limiting plate, an adjusting plate, a fixing bolt, a rotating seat, a connecting seat, a mounting plate, a guide rod, and straps. A limiting plate is slidably installed on the rear side of the placement frame to restrict the position of the rabbit's rear end. The adjusting plate has two support rods with threaded ends on its front sides, which slide through the front end of the placement frame. A matching notch is opened on the side of the adjusting plate that is close to the placement frame, and the two notches are used to place the rabbit's head. A fixing bolt is also threaded onto the support rod and abuts against the front end of the placement frame to fix the position of the adjusting plate after sliding. A rotating seat is hinged to both sides of the adjusting plate, and a connecting seat is hinged to each rotating seat. A mounting plate is connected to each connecting seat, and a guide rod is installed on each mounting plate. A set of spaced straps is slidably installed on each guide rod to fix the position of the rabbit's ear.

[0006] Furthermore, it also includes a mounting base, a sliding rod, and a locking plate. One side of the connecting base has slots arranged at intervals along the circumference. A mounting base on the same side as the slots is provided on the rotating base. A sliding rod is slidably mounted through the mounting base. A locking plate that engages with the adjacent slot is provided on the sliding rod to fix the position of the mounting plate.

[0007] Furthermore, it also includes an elastic element, with an elastic element provided between the slide rod and the corresponding mounting base.

[0008] Furthermore, it also includes a grip bar, which is provided between the two rear sides of the placement frame for gripping operation.

[0009] Furthermore, it also includes a lighting fixture, with a lighting fixture for illuminating the rabbit ears located on the rear side of the mounting plate.

[0010] Furthermore, the mounting plate is made of a transparent material.

[0011] The beneficial effects are as follows: This invention, through the combination of a placement frame, a limiting plate, and an adjusting plate, can stably position the rabbit's body, effectively preventing movement during injection. This not only improves the safety of the injection process but also reduces stress on the animal. Furthermore, the device employs a rotating design with a connecting seat and a rotating seat, and the mounting plate angle is flexibly adjustable to accommodate the ear positions of different rabbits. Combined with the mounting plate and straps, the rabbit's ears can be precisely fixed, ensuring they can be properly unfolded for accurate location of veins, providing great convenience for researchers.

Detailed Implementation

[0017] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and to fully convey the scope of the invention to those skilled in the art.

[0018] Example: A fixator for visual marginal ear vein injection in rabbits, such as... Figures 1-4 As shown, the device includes a placement frame 1, a limiting plate 2, an adjusting plate 3, a fixing bolt 4, a rotating seat 5, a connecting seat 6, a mounting plate 7, a guide rod 8, and a strap 9. The placement frame 1 serves as the basic structure of the entire fixture. Its interior is hollow and primarily used to place the experimental rabbits. A limiting plate 2 is slidably installed on the rear side of the placement frame 1 to restrict the rabbit's rear end position. The limiting plate 2 slides forward and backward, allowing the space inside the placement frame 1 to be expanded or reduced, effectively adjusting the rabbit's movement space and restricting its tail position, thus achieving the effect of adjusting the overall position of the rabbit. The adjusting plate 3 has a support rod with a threaded front end on both the left and right sides of its front part (see details). Figure 3The support rods are arranged along the front and rear edges. The front end of the placement frame 1 has symmetrical slots along the top and bottom edges. Two support rods slide through these slots on the same side, allowing the adjustment plate 3 to slide up and down by pushing the support rods. The adjustment plate 3 has matching notches on the side closest to the placement frame 1. These notches are aligned and joined together to form a ring for placing the rabbit's head. This, combined with the limiting plate 2, fixes the rabbit's head and tail, ensuring stability and safety during the experiment. The support rods also have threaded fixing bolts 4 that abut against the front end of the placement frame 1 to secure the adjustment plate 3 after adjustment. Rotary seats 5 are hinged on both sides of the adjustment plate 3. Dampers are built into the hinges between the rotating seats 5 and the adjustment plate 3 to stabilize the position of the rotating seats 5 after rotation. The rotating seats 5 are located at the top of the adjustment plate 3. The rotating seat 5 rotates circumferentially in the left and right directions. Each rotating seat 5 is hinged with a connecting seat 6, which rotates in the front and back directions. A mounting plate 7 is fixedly connected to the end of the connecting seat 6. The mounting plate 7 is made of transparent material. The rotating seat 5 is first rotated to adjust the overall tilt position. Then, the mounting plate 7 is unfolded by rotating the connecting seat 6, so that the two sides of the mounting plate 7 are opened to form a shape similar to a rabbit ear and provide a platform for placement. Because the mounting plate 7 is made of transparent material, the subsequent ear vein injection operation can be visualized, which is convenient for observing the rabbit ear blood vessels and thus ensuring the implementation of the experimental operation. Each mounting plate 7 is provided with a guide rod 8, and a set of spaced straps 9 are slidably arranged on the guide rod 8. Velcro is provided on the back of the mounting plate 7 so that the straps 9 can be glued and fixed, thereby fixing the position of the rabbit ear.

[0019] Specifically, in conjunction with the above, the position of the mounting plate 7 used for placing the injection rabbit ear can be flexibly adjusted through the coordinated operation of the rotating seat 5 and the connecting seat 6. Furthermore, the binding and fixing with the strap 9 can securely restrict the injection site, reduce the operator's workload, and maintain the injection state of the rabbit ear to ensure the accuracy and safety of subsequent marginal ear vein injection.

[0020] like Figure 4 As shown, it also includes a mounting base 10, a slide rod 11, and a locking plate 12. One side of the connecting base 6 has slots 16 arranged at intervals along the circumference. The rotating base 5 is provided with a mounting base 10 on the same side as the slots 16. The slide rod 11 is slidably arranged through the mounting base 10. The slide rod 11 is provided with a locking plate 12 that engages with the adjacent slots 16 to fix the position of the mounting plate 7, thereby forming a stable locking mechanism so that the mounting plate 7 can be fixed by the locking plate 12 once the angle is adjusted.

[0021] like Figure 4As shown, it also includes an elastic element 13. An elastic element 13 is provided between the slide bar 11 and the corresponding mounting base 10. In this embodiment, the elastic element 13 is a spring, which can provide the elastic restoring force required for the reset of the card plate 12 and the slide bar 11.

[0022] like Figure 2 As shown, it also includes a gripping rod 14. The gripping rod 14 is provided between the two rear sides of the placement frame 1 for gripping operation, providing the operator with a convenient gripping point to assist in the overall positional movement of the placement frame 1.

[0023] like Figure 3 As shown, it also includes a lighting lamp 15. The lighting lamp 15 for illuminating rabbit ears is provided on the rear side of the mounting plate 7. It is used to illuminate rabbit ears to help the operator see the location of blood vessels more clearly, thereby improving the accuracy of injection.

[0024] When using this device, first gently place the rabbit into the placement frame 1, and adjust its rear end position by sliding the limiting plate 2 to ensure that the limiting plate 2 fits snugly against the rabbit's tail. Then, gently push the rabbit forward so that its head naturally moves between the adjusting plate 3 and the notch at the front of the placement frame 1. Next, slowly press down the adjusting plate 3, allowing it to slide along the front of the placement frame 1 until the notches on both sides accurately fit the rabbit's head. At this point, rotate the fixing bolt 4 on the support rod until the fixing bolt 4 contacts the front of the placement frame 1, thereby fixing the position of the adjusting plate 3 and ensuring that the rabbit's head remains stable. Subsequently, rotate the rotating seats 5 on both sides. Since the locking plate 12 and the connecting seat 6 are in a locked state, the connecting seat 6 remains fixed. As the rotating seat 5 rotates, the angle of its upper components along with the mounting plate 7 can be adjusted. After the rotating base 5 is adjusted to the appropriate position, the mounting plate 7 is unfolded. First, push the retaining plate 12 corresponding to one ear, causing the retaining plate 12 to slide away from the connecting base 6 on the mounting base 10 along with the connected sliding rod 11. At the same time, the elastic element 13 deforms, causing the retaining plate 12 to disengage from the slot 16 on the connecting base 6. Then, the connecting base 6 can be rotated to adjust the unfolded position of the mounting plate 7, allowing it to fit snugly against the back of the rabbit ear, ensuring the rabbit ear is placed stably on the mounting plate 7. After releasing the retaining plate 12, the elastic element 13 returns to its original shape, causing the sliding rod 11 and retaining plate 12 to reset and engage in the adjacent slot 16, thus fixing the relative position between the connecting base 6 and the rotating base 5. Next, use the straps 9 to secure the rabbit ear to the mounting plate 7. By sliding the straps 9 on the guide rod 8, the distance between the two straps 9 can be adjusted. The straps 9 are then fixed to the back of the mounting plate 7 using Velcro. Repeat the above steps to secure the other ear in the same way. Finally, prepare to perform intravenous injection on the rabbit's ear. Turn on the light 15, and let the light shine through the mounting plate 7 to illuminate the rabbit's ear, clearly showing the location of the blood vessels, so as to perform professional ear vein injection.

[0025] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
