Description

Technical Field

[0001] This utility model relates to the field of animal experimental anatomy technology, and in particular to a laboratory rabbit operating table. Background Technology

[0002] Rabbits are frequently used as experimental subjects in pharmacology and biomedical experiments. During these experiments, a dissection table, also called a worktable, is indispensable. Traditional rabbit dissection tables are typically simple in design and have limited functionality, providing only basic animal restraint (limbs and teeth restraints) to ensure animal stability during the procedure.

[0003] Therefore, how to provide a practical laboratory rabbit operating table has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a laboratory rabbit operating table, which overcomes the shortcomings of the existing dissection table in terms of its single function and poor practicality. At the same time, this utility model also solves some other technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A laboratory rabbit operating table includes an operating panel. Unlike existing technologies, one end of the operating panel is provided with a rabbit ear-shaped groove for placing rabbit ears. The ear groove is made of a transparent or semi-transparent material, and a light source is provided at the bottom. The brightness of the light source is adjustable.

[0007] An infrared display is provided on the edge of the operation panel; the infrared display includes a display body, a bracket, and a fixing base; the display body is rotatably connected to the bracket, and the display body can rotate around the bracket in a horizontal plane; the bracket is a telescopic structure, erected on one side of the operation panel, and the bottom of the bracket is fixedly connected to the fixing base; the fixing base is detachably fixed to the operation panel.

[0008] In laboratory settings, when performing ear injections on rabbits, the small size of the ear veins and their visibility, which varies greatly among rabbits, especially in those with indistinct veins, make accurate visual location difficult. This can lead to repeated needle insertions due to inaccurate positioning, increasing the rabbit's pain and stress, potentially causing unstable results, and even complications such as local bleeding and tissue damage. To address this issue, this invention incorporates a rabbit-shaped ear recess, allowing the rabbit's ear to be placed within it. Combined with a bottom-mounted light source and an infrared imaging device, this provides rapid assistance in vascular localization. By integrating the ear recess design, bottom light source, and vein imaging device onto the dissection table, this invention helps researchers locate ear veins more quickly and accurately, avoiding repeated insertions and unnecessary manipulations, thereby reducing the error rate, minimizing rabbit pain, and ensuring stable experimental results.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, there are two ear recesses, arranged side by side at the same end of the operation panel.

[0011] Furthermore, two "F"-shaped locking blocks are slidably connected to the upper edge of the ear groove, the two locking blocks are arranged opposite to each other, and the upper surface of the locking blocks is flat.

[0012] Furthermore, the ear recess is detachably embedded in the operation panel, and the ear recess is available in various sizes. When in use, the appropriate ear recess is selected according to the size of the experimental rabbit's ears and connected to the operation panel.

[0013] Furthermore, the operation panel is equipped with a limb fixation device for fixing the experimental rabbit. The limb fixation device includes a strap and a slider. A groove is opened on the operation panel. The strap is connected to the slider. The slider is slidably connected to the groove. The slider can slide within the groove.

[0014] Furthermore, a heating device is provided at the bottom of the ear recess, and a temperature control panel is provided on the operation panel to control the temperature of the heating device.

[0015] Furthermore, the bottom of the control panel is equipped with a height-adjustable support device.

[0016] Furthermore, the support device is a multi-link scissor lift structure.

[0017] Furthermore, the scissor lift structure includes an upper scissor lift, a lower scissor lift, a middle connecting rod, an adjusting screw, and a base;

[0018] The upper scissor lift is a scissor lift structure, with its upper part connected to the bottom of the operation panel and its lower part hinged to the lower scissor lift.

[0019] The lower scissor fork is a scissor fork structure, with its upper part hinged to the upper scissor fork and its lower part connected to the base;

[0020] There are two intermediate connecting rods, located between the upper scissor fork and the lower scissor fork;

[0021] The two intermediate connecting rods have screw holes with opposite directions of rotation. The adjusting screw has an external thread that matches the screw holes. The adjusting screw is screwed to both intermediate connecting rods. By rotating the adjusting screw, the upper and lower scissor forks are driven to retract or open.

[0022] Furthermore, the base is equipped with casters at its bottom.

[0023] The laboratory rabbit operating table disclosed in this utility model has the following beneficial technical effects compared with the prior art:

[0024] 1. Improved accuracy: By integrating a vein imaging device into the dissection table, medical staff can quickly and accurately locate the veins on the rabbit's ear margin, thereby improving the success rate of injection.

[0025] 2. Improved stability: The ear groove design ensures that the rabbit's ears are fixed and stable, reducing the rabbit's movement during operation and thus reducing the risk of misoperation.

[0026] 3. Improved visibility: The integrated bottom light source system enhances the visibility of the auricular vein, enabling clear operation even in low-light environments and reducing visual stress on experimenters.

[0027] 4. Simplified operation process: Through integrated design, the imaging equipment, light source and fixing device are combined on one platform, which reduces the need for experimental personnel to use multiple devices, simplifies the operation steps and improves work efficiency.

[0028] 5. The ear groove has a sliding clip on the edge, which can help to stick and fix the tape to the needle. It is simple to operate and highly practical.

[0029] 6. The ear canal is equipped with a heating device to keep the ear warm, which is conducive to vein dilation and is suitable for operation in cold environments, making injection easier.

[0030] 7. The bottom is equipped with a height-adjustable support device, which can accommodate operators of different heights, reduce fatigue during long-term operation, and improve operational accuracy. Attached Figure Description

[0037] The principles, features, and beneficial technical effects of this utility model are described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The examples given are only for explaining this utility model and are not intended to limit its scope. Furthermore, the omission of some components does not indicate a design defect or unclear principle description, but rather reflects that such parts are feasible under existing technology.

[0038] Please refer to Figures 1 to 4 , Figure 1 A three-dimensional structural schematic diagram of a specific embodiment of a laboratory rabbit operating table provided by this utility model; Figure 2 for Figure 1 A partially enlarged structural schematic diagram of a specific embodiment is shown below; Figure 3 This is a partially enlarged structural schematic diagram of a specific embodiment of the ear groove portion shown.

[0039] Figure 4 This is a three-dimensional structural diagram of a specific embodiment of the support device.

[0040] A laboratory rabbit operating table includes an operating panel 1. Unlike the prior art, one end of the operating panel 1 is provided with a rabbit ear-shaped ear groove 2 for placing rabbit ears. The ear groove 2 is made of transparent or semi-transparent material. A light source 3 is provided at the bottom, and the brightness of the light source 3 is adjustable.

[0041] An infrared imager 4 is provided on the edge of the operation panel 1. The infrared imager 4 includes an imager body 41, a bracket 42, and a fixing base 43. The imager body 41 is rotatably connected to the bracket 42, and the imager body 41 can rotate around the bracket 42 in a horizontal plane. The bracket 42 is a telescopic structure, such as a telescopic rod, and is erected on one side of the operation panel 1. The bottom of the bracket 42 is fixedly connected to the fixing base 43. The fixing base 43 is detachably fixed to the operation panel 1. The fixing base 43 can be a snap-fit ​​structure or a flexible clip.

[0042] The connection between the ear recess 2 and the operating panel 1 can be achieved in various ways, such as a magnetic structure. The operating panel 1 has a groove, and the ear recess 2 is made of transparent acrylic material, which is lightweight and low-cost. Soft materials such as silicone or rubber are added to the edges and bottom of the ear recess 2 to ensure that the rabbit ear is not compressed by hard materials when placed. The ear recess 2 is semi-open in an "()" shape, allowing the distal end of the ear to be exposed during placement, facilitating angle adjustment during injection.

[0043] The ear recess 2 has a double-layer structure, with the upper layer for the ear and the lower layer for the light strip, which can be LED or other types of LEDs.

[0044] The ear groove 2 consists of two parts, which are arranged side by side at the same end of the operation panel 1.

[0045] The two ear recesses 2 allow operators to choose different positions for ear placement, or to perform injections on both ears simultaneously.

[0046] Two "F"-shaped locking blocks are slidably connected to the upper edge of the ear groove 2. The two locking blocks are arranged opposite each other, and the upper surface of the locking blocks is flat. The "F" shape makes it easy for the operator to move the block.

[0047] Specifically, the two locking blocks are respectively secured at the top edges of the ear recess 2 and can slide. The flat surface of the top of the locking blocks can be used to attach and fix the adhesive tape. During operation, first move the locking block to one end, attach the fixing tape, leaving some slack to accommodate the need for the locking block to move towards the center and increase its relative position. After inserting the needle into the ear rim, move the locking block to the appropriate position, and then cut the tape. This will fix the needle, rabbit ear, and ear recess 2 into one unit, ensuring that the needle will not slip out of the rabbit ear. This structure not only improves accuracy but, more importantly, frees up the operator's hands, greatly enhancing convenience.

[0048] The ear recess 2 is detachably embedded in the operation panel 1, and the ear recess 2 is available in various sizes. During use, the appropriate ear recess 2 is selected according to the size of the experimental rabbit's ear and connected to the operation panel 1. The ear recess 2 is detachable, which not only allows for selection of a suitable ear recess 2 according to the size of the rabbit's ear, but also facilitates cleaning and can even be used for injections in other small animals.

[0049] The operation panel 1 is provided with a limb fixation device 6 for fixing the experimental rabbit. The limb fixation device 6 includes a strap 61 and a slider 62. The operation panel 1 has a groove 7. The strap 61 is connected to the slider 62. The slider 62 is slidably connected to the groove 7. The slider 62 can slide within the groove 7.

[0050] The design of slider 62 and groove 7 allows for adjustment of the position of the limb fixation device 6 to ensure it can accommodate the limb positions of rabbits of different sizes. The groove 7 can be either straight or curved.

[0051] A heating device is provided at the bottom of the ear groove 2. A temperature control panel 8 is provided on the operation panel 1. The temperature of the heating device is controlled by the temperature control panel 8.

[0052] In terms of control, the control switches for the lighting source 3, infrared imager 4, and heating device can be integrated on the temperature control panel 8 for easy operation and quick adjustment.

[0053] The heating device can be in the form of a heating wire or in the form of blowing hot air; this utility model does not limit either option.

[0054] At the bottom of the operation panel 1, a height-adjustable support device 9 is provided. Specifically, the support device 9 is a multi-link scissor lift structure. Figure 4 As shown, the scissor lift structure includes an upper scissor lift 91, a lower scissor lift 92, a middle connecting rod 93, an adjusting screw 94, and a base 95.

[0055] The upper scissor fork 91 is a scissor structure, that is, a scissor-like structure. Through the hinge of the connecting rod, a multi-link scissor structure is realized. Its upper part is connected to the bottom of the operation panel 1, and its lower part is hinged to the lower scissor fork 92.

[0056] The lower scissor fork 92 is a scissor fork structure, with its upper part hinged to the upper scissor fork 91 and its lower part connected to the base 95;

[0057] Two intermediate connecting rods 93 are located between the upper scissor fork 91 and the lower scissor fork 92. The two intermediate connecting rods 93 have screw holes with opposite directions of rotation. An adjusting screw 94 has an external thread that matches the screw holes. The adjusting screw 94 is screwed to both intermediate connecting rods 93. By rotating the adjusting screw 94, the upper scissor fork 91 and the lower scissor fork 92 are driven to retract or open. The screw holes with opposite directions of rotation on the two intermediate connecting rods 93 ensure that when the screws rotate in one direction, the two screws can simultaneously move inwards or away from each other, thus realizing the retraction or opening of the scissor fork structure. The base 95 has rollers 10 at its bottom.

[0058] The height-adjustable dissection table support device 9 adds a height adjustment function to the overall structure of the dissection table, making it suitable for operators of different heights, reducing fatigue during long-term operation, and improving operational accuracy. The base 95 bracket 42 is designed as a telescopic bracket 42, and the table height can be controlled by tightening the screws.

[0059] The core of the lifting platform is the central "scissor" structure, which consists of two sets of intersecting metal arms. This structure keeps the lifting platform smooth and stable during extension and retraction. When the screw rotates, the scissor structure is pushed, causing the upper and lower metal plates of the lifting platform to move relative to each other, thereby changing the height of the platform. Due to the self-locking property between the screw and the nut, the platform will remain at the current height and will not automatically slide down due to gravity after the knob stops rotating. This self-locking property ensures that the platform is stable after the position is adjusted.

[0060] In addition, casters 10 are provided at the bottom of the support device 9 to facilitate the movement of the dissection table.

[0061] In summary, the laboratory rabbit operating table disclosed in this utility model integrates vein imaging technology and auxiliary light source, solving the problems of difficult injection and increased experimental error caused by indistinct ear veins in rabbits during experiments. The technical solution mainly includes the following parts:

[0062] 1. Dissection table design

[0063] Ear recess design: The head of the dissection table is equipped with a special ear recess for securing the rabbit's ears. The recess is designed according to the shape of the rabbit's ears to ensure that the rabbit's ears can be stably and comfortably fixed on the dissection table during injection, avoiding interference from ear movement during the injection procedure.

[0064] Bottom Light Source: An adjustable brightness light source is embedded beneath the dissection table, with the light directed towards the rabbit's ear margin area within the ear canal. This uniform illumination improves the visibility of the ear margin veins and reduces operational difficulties caused by insufficient light. The brightness and angle of the light source can be manually adjusted to suit different experimental conditions.

[0065] 2. Vein imaging device

[0066] Vein imaging technology: An infrared vein imaging device is integrated above or beside the dissection table. This device illuminates the marginal ear vein area of ​​rabbits with near-infrared light, utilizing the absorption characteristics of blood in the vessels to enhance the imaging effect of the marginal ear veins. During the injection procedure, the experimenter can clearly see the morphology and location of the marginal ear veins through the display screen or projector of the imaging device, facilitating precise positioning and injection.

[0067] Display and Adjustment Functions: The imaging system is equipped with a high-definition display for real-time display of vein images. Researchers can adjust the position, angle, and imaging parameters of the imaging system based on the characteristics of the rabbit's ear and the desired imaging effect to ensure optimal vein visualization. Furthermore, the display has zoom and contrast adjustment functions, facilitating injection procedures under varying lighting conditions.

[0068] 3. Bottom support device

[0069] The control panel is raised and lowered using a scissor mechanism to accommodate operators of different heights.

[0070] 3. Operating Procedures

[0071] 1) The experimenters placed the rabbit on the dissection table, used ear grooves to fix the rabbit's ears, and adjusted the limb fixation devices to ensure that the rabbit did not move around.

[0072] 2) Turn on the bottom lighting source and adjust the light angle and brightness to optimize the lighting in the ear vein area.

[0073] 3) Turn on the vein imaging device and adjust the imaging angle of the device so that the rabbit's ear vein is clearly displayed on the screen.

[0074] 4) Based on the vein location provided by the vein imaging device, the experimenter uses a catheter holder to fix the injection needle and performs an auricular vein injection. The image displayed on the imaging device allows for precise guidance of the needle into the vein, reducing the risks associated with repeated punctures.
