Description

Technical Field

[0001] This utility model relates to the field of animal disease detection technology, specifically a fixed sampling device for animal disease detection. Background Technology

[0002] In the field of animal disease detection, animal sampling is necessary to obtain accurate results. Currently, animal disease detection sampling commonly uses restraints, nose clamps, and muzzles to immobilize animals and assist in the sampling process. When collecting blood samples, different animals have specific blood collection sites, such as the anterior vena cava and marginal ear veins in pigs, and the wing veins and heart in poultry. Collecting tissue samples, such as lymph nodes and liver, requires aseptic techniques. During the sampling process, tools such as sampling boxes, scalpels, and forceps are used. Overall, existing technologies cover a variety of immobilization methods and sampling techniques, laying the operational foundation for animal disease detection sampling.

[0003] Existing animal disease testing and sampling fixation equipment cannot sense clamping pressure. Overly tight fixation may cause excessive pressure on the animal's body, resulting in injuries such as bruises and fractures, or even triggering stress-related diseases that affect the animal's health. At the same time, because the animal cannot adjust its strength in time when struggling, the fixation is prone to loosening, causing the animal to move, affecting the accuracy of the sampling operation, and increasing the sampling difficulty and time cost. In addition, when the animal's limbs are not restricted, the existing animal disease testing and sampling fixation equipment will cause the body to shake through kicking, twisting and other movements, which will disperse the clamping force of the body fixation components and may cause the body fixation to loosen.

[0004] Therefore, this utility model provides a fixed device for animal disease detection and sampling to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fixation device for animal disease detection sampling. Through a dynamic adjustment component, it can adjust in real time according to the animal's struggles and other dynamic situations, maintaining a suitable clamping force at all times. This prevents injury to the animal's body due to excessive tightness. The four-leg fixation component can specifically fix the animal's limbs, adapting to limbs of different thicknesses, preventing the animal from moving its limbs during sampling and affecting the fixation effect. This provides stable limb restraint for the sampling operation, reduces the intensity of animal struggle, and solves the aforementioned problems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-3 A fixed device for sampling animal disease detection includes a support platform 10. Support plates 11 are fixedly connected to the bottom front and rear sides of the support platform 10. Anti-slip pads 12 are fixedly connected to the bottom of the front and rear support plates 11. A central controller 13 is fixedly connected to the front side of the front anti-slip pad 12. Two straight slot holes 14 with left and right orientation are opened in the middle of the top of the support platform 10. Pressure dynamic adjustment components 2 are provided on the upper and lower sides of the middle of the support platform 10. Four rectangular four-legged fixing components 3 are provided on the top of the support platform 10.

[0024] The pressure dynamic adjustment component 2 includes a fixed base plate 20. Ear seats 21 are fixedly connected to both the front and rear sides of the fixed base plate 20. The top of the front and rear ear seats 21 is fixedly connected to a fixing rod 22 that is fixedly connected to the bottom of the support platform 10. A motor 23 is fixedly connected to the middle of the bottom end of the fixed base plate 20. The output end of the motor 23 extends through to the top of the fixed base plate 20 and is fixedly connected to a gear 24.

[0025] The top front and rear sides of the fixed base plate 20 are fixedly connected to slide rails 25. The outer walls of the two slide rails 25 are slidably connected to two left and right symmetrical slide blocks 26. The rear side of the gear 24 is meshed with a rack 27, which is fixedly connected to the rear inner wall of the right slide block 26. The front side of the gear 24 is meshed with a rack 28, which is fixedly connected to the front inner wall of the left slide block 26.

[0026] Two movable rods 29 are fixedly connected to the top of each of the two left and right slides 26. The tops of the four movable rods 29 extend through to the top of the support platform 10 and their outer walls are slidably connected to the inner walls of the two straight slot holes 14 respectively. Two arc-shaped clamping blocks 290 are fixedly connected to the outer walls of the four movable rods 29. The two arc-shaped clamping blocks 290 are symmetrically arranged on the left and right sides and pressure sensors 291 are fixedly connected to their opposite faces. The central controller 13 is electrically connected to the motor 23 and the pressure sensors 291 respectively.

[0027] The pressure dynamic adjustment component 2 achieves adaptive fixation of the animal body through motor drive and pressure feedback. After receiving the start command, the central controller 13 outputs a control signal to the motor 23. The output shaft of the motor 23 drives the gear 24 to rotate. The gear 24 simultaneously meshes with rack 1 27 and rack 28. Rack 1 27 drives the right slide 26 to slide to the left along the slide rail 25, and rack 28 drives the left slide 26 to slide to the right along the slide rail 25. The two slides 26 move towards each other, and the moving rod 29 at the top of the slide 26 slides synchronously along the inner wall of the straight slot hole 14, pushing the two arc-shaped clamps 290 to close towards the animal body. When the arc-shaped clamps 290 contact the animal body, the pressure sensor 291 on its surface converts the mechanical pressure into an electrical signal, which is transmitted to the sampling port of the central controller 13 in real time. If the sensor detects the current signal, the central controller 13 will automatically adjust the pressure accordingly. When the pressure is below the preset threshold, the central controller 13 maintains the output power of the motor 23. When the pressure reaches the threshold, the controller immediately outputs a reverse pulse signal to decelerate the motor 23 and maintain the clamping state. If the animal struggles and the pressure exceeds the safety threshold, the controller triggers the motor 23 to reverse. Through the meshing transmission of the gear 24 and the rack, the arc-shaped clamp 290 moves in the opposite direction until the pressure returns to the safe range, realizing dynamic pressure closed-loop control. Through the set pressure dynamic adjustment component 2, it can adjust in real time according to the dynamic situation such as the animal's struggle, always maintaining a suitable clamping force to prevent the animal from moving due to loose fixation, ensuring the smooth progress of the sampling process, reducing the probability of sampling failure. At the same time, when the pressure approaches the threshold that may harm the animal, the force is automatically reduced to avoid injury to the animal's body due to excessive fixation.

[0028] Example 2:

[0029] Please see Figure 3 This embodiment provides a technical solution based on embodiment one: the four-legged fixing component 3 includes a cross slide groove 30, which is opened on the top of the support platform 10. A cross slider 31 is slidably connected inside the cross slide groove 30. A movable plate 32 is fixedly connected to the top of the cross slider 31. A fixed frame 33 is fixedly connected to the side of the movable plate 32 near the edge of the support platform 10. A threaded rod 34 is threadedly connected to the side of the fixed frame 33 near the edge of the support platform 10 through a threaded hole. An adjustment knob 35 is fixedly connected to the end of the threaded rod 34 away from the movable plate 32.

[0030] The threaded rod 34 is rotatably connected to an arc-shaped clamping block 36 near the moving plate 32. Limiting grooves 37 are provided on both the front and rear sides of the fixed frame 33. Limiting rods 38 are fixedly connected to both the front and rear sides of the arc-shaped clamping block 36, respectively slidingly connected to the inner walls of the two limiting grooves 37.

[0031] During the limb fixation stage, the operator places the animal in the central area of ​​the support platform 10 and fixes the animal's body using the pressure dynamic adjustment component 2. Then, the operator manually pushes the moving plate 32 to make the cross slider 31 slide along the cross groove 30 until the four four-leg fixation components 3 are aligned with the animal's forelimbs and hindlimbs respectively. At this time, the operator rotates the adjustment knob 35, and the threaded rod 34 is driven by the threaded hole on the fixing frame 33. The end of the threaded rod 34 near the moving plate 32 pushes the arc-shaped clamping block 36 to move linearly through the deep groove ball bearing. During the process, the limiting rod 38 is embedded in the limiting groove 37 to guide the sliding, ensuring that the arc-shaped clamping block 36 clamps the animal's limbs in a direction parallel to the moving plate 32. The clamping range can be precisely controlled by the number of rotations of the threaded rod 34. Through the four-leg fixation components 3, the animal's limbs can be fixed in a targeted manner, adapting to limbs of different thicknesses, avoiding the animal's body fixation effect due to limb movement during sampling, providing stable limb restraint for sampling operations, and reducing the intensity of animal struggle.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, the pressure dynamic adjustment component 2 first achieves adaptive fixation of the animal body through motor drive and pressure feedback. After receiving the start command, the central controller 13 outputs a control signal to the motor 23. The output shaft of the motor 23 drives the gear 24 to rotate. The gear 24 simultaneously meshes with rack 1 27 and rack 2 28. Rack 1 27 drives the right slide 26 to slide to the left along the slide rail 25, and rack 2 28 drives the left slide 26 to slide to the right along the slide rail 25. The two slides 26 move towards each other, and the moving rod 29 on the top of the slide 26 slides synchronously along the inner wall of the straight slot hole 14, pushing the two arc-shaped clamps 290 to close towards the animal body. When the arc-shaped clamps 290 contact the animal body, the pressure sensor 291 on its surface converts the mechanical pressure into an electrical signal, which is transmitted to the sampling port of the central controller 13 in real time. If the detected pressure is lower than the preset threshold, the central controller 13 maintains the output power of the motor 23. When the pressure reaches the threshold, the controller immediately outputs a reverse pulse signal to decelerate the motor 23 and maintain the clamping state. If the animal struggles and the pressure exceeds the safety threshold, the controller triggers the motor 23 to reverse. Through the meshing transmission of the gear 24 and the rack, the arc-shaped clamp 290 moves in the reverse direction until the pressure returns to the safe range, realizing dynamic pressure closed-loop control. Through the set pressure dynamic adjustment component 2, it can adjust in real time according to the dynamic situation such as the animal's struggle, always maintaining a suitable clamping force to prevent the animal from moving due to loose fixation, ensuring the smooth progress of the sampling process, reducing the probability of sampling failure. At the same time, when the pressure approaches the threshold that may harm the animal, the force is automatically reduced to avoid injury to the animal's body due to excessive fixation.

[0034] During the limb fixation stage, the operator places the animal in the central area of ​​the support platform 10 and fixes the animal's body using the pressure dynamic adjustment component 2. Then, the operator manually pushes the moving plate 32 to make the cross slider 31 slide along the cross groove 30 until the four four-leg fixation components 3 are aligned with the animal's forelimbs and hindlimbs respectively. At this time, the operator rotates the adjustment knob 35, and the threaded rod 34 is driven by the threaded hole on the fixing frame 33. The end of the threaded rod 34 near the moving plate 32 pushes the arc-shaped clamping block 36 to move linearly through the deep groove ball bearing. During the process, the limiting rod 38 is embedded in the limiting groove 37 to guide the sliding, ensuring that the arc-shaped clamping block 36 clamps the animal's limbs in a direction parallel to the moving plate 32. The clamping range can be precisely controlled by the number of rotations of the threaded rod 34. Through the four-leg fixation components 3, the animal's limbs can be fixed in a targeted manner, adapting to limbs of different thicknesses, avoiding the animal's body fixation effect due to limb movement during sampling, providing stable limb restraint for sampling operations, and reducing the intensity of animal struggle.
