Description

Technical Field

[0001] The invention relates to the technical field of pain assessment, in particular to an instrument for assessing pain in rabbit lower limbs. Background Art

[0002] In the field of pain research, pain assessment of animal models is an important basis for understanding pain mechanisms and developing new analgesics. As one of the commonly used experimental animals, the establishment and evaluation of rabbit lower limb pain models is of great significance for pain research. However, traditional methods for assessing rabbit lower limb pain often rely on observing the behavioral responses of rabbits or manual touch judgment. These methods are highly subjective, inaccurate, and difficult to quantify. Therefore, it is particularly important to develop an instrument that can objectively, accurately, and quantitatively evaluate rabbit lower limb pain.

[0003] Although there are some pain assessment instruments on the market, these instruments are often designed for specific types of animals or pain sites, and are not completely applicable to the assessment of rabbit lower limb pain. In addition, these instruments may be complicated to operate, requiring professional personnel to operate, and are expensive, which is not conducive to widespread application. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a rabbit lower limb pain assessment instrument, which implements rabbit lower limb pain assessment by limiting the rabbit through a limiting component and combining the balance load detection to solve the problems that traditional equipment assessment is not applicable, the operation and use are complicated, the cost is high, and it cannot be widely used.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A rabbit lower limb pain assessment instrument comprises a base plate, and also comprises: mounting plates fixedly arranged on both sides of the base plate, the inner side walls of the mounting plates are fixedly connected to a support plate, the support plate is an L-shaped structure, a limit assembly is arranged above the support plate, a left balance and a right balance are respectively arranged on both sides of the base plate below the support plate, and a balance tray is arranged on the left balance and the right balance.

[0007] As a preferred technical solution of the present invention, the limiting assembly includes mounting blocks fixedly arranged on the front and rear sides of the support plate, the limiting enclosures are rotatably connected between the mounting blocks, baffles and inclined covers are respectively arranged between the limiting enclosures, movable grooves are opened on both sides of the inner wall of the limiting enclosure, the baffles and inclined covers are arranged in the movable grooves on both sides and are slidably connected with the enclosures to adjust the size of the limiting space to adapt to rabbits of different sizes.

[0008] As a preferred technical solution of the present invention, the left balance and the right balance are connected to a data processing unit via precision sensors. The data processing unit can receive the readings of the balance in real time and calculate the difference between the readings of the balances on both sides to evaluate the pain level of the rabbit's lower limbs.

[0009] As a preferred technical solution of the present invention, the surface of the balance tray is provided with anti-skid patterns to increase the friction between the balance tray and the rabbit's limbs and prevent the rabbit from sliding or falling during the experiment.

[0010] As a preferred technical solution of the present invention, the instrument also includes a display screen for displaying balance readings and data processing results. The display screen is connected to the data processing unit and can display the pain assessment results of the rabbit's lower limbs in real time.

[0011] As a preferred technical solution of the present invention, support feet with adjustable height are arranged under the bottom plate, and the height of the support feet can be adjusted by a knob so as to adjust the overall height of the instrument according to experimental requirements.

[0012] The present invention has the following benefits:

[0013] The rabbit lower limb pain assessment instrument of the present invention realizes an objective, accurate and quantitative assessment of rabbit lower limb pain through the following technical schemes, and has significant beneficial effects: Improving assessment accuracy: The present invention places a rabbit on a balance tray and limits the rabbit using a limit assembly to ensure stability during the assessment process.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] Example 1, please refer to Figure 1-Figure 2 , a rabbit lower limb pain assessment instrument, comprising a base plate 1, and also comprising: mounting plates 3 fixedly arranged on both sides of the base plate 1, the inner side walls of the mounting plates 3 are fixedly connected to support plates 5, the support plates 5 are L-shaped structures, a limiter assembly is arranged above the support plate 5, a left balance 2 and a right balance 9 are arranged on both sides of the base plate 1 below the support plate 5, and a balance tray 4 is arranged on the left balance 2 and the right balance 9;

[0019] During actual use, the rabbit that needs to be assessed for pain is placed between the limit components. The limit components serve as a limit fence for the rabbit, which can ensure that the pain assessment measurement is more stable and accurate. During the measurement process, if the rabbit has pain in one limb, the rabbit's leg is in a contracted state, and the balance reading on the corresponding side will be very small or even no data. Almost all of the rabbit's weight falls on the other side of the balance. By observing the indication of the corresponding balance and the changes in the indication, the operator can understand which specific limb of the rabbit is injured, and thus can accurately and quickly evaluate the rabbit's injury.

[0020] Example 2, please refer to Figure 1-Figure 2 The limiting assembly includes mounting blocks 6 fixedly arranged on the front and rear sides of the support plate 5, and the limiting enclosure plates 7 are rotatably connected between the mounting blocks 6. A baffle plate 8 and an inclined cover 10 are respectively arranged between the limiting enclosure plates 7. Active grooves 11 are provided on both sides of the inner wall of the limiting enclosure plates 7. Both sides of the baffle plate 8 and the inclined cover 10 are arranged in the active grooves 11 and are slidably connected with the enclosure plates 7 to adjust the size of the limiting space to adapt to rabbits of different sizes. When actually used, since the rabbit may have an unstable body shape, the limiting enclosure plates 7 can be rotated and adjusted during actual use, thereby achieving better limiting of the rabbit, making the device more flexible to use. At the same time, under the action of the inclined cover 10, the surrounding limiting of the rabbit can be achieved.

[0021] The left-side balance 2 and the right-side balance 9 are both connected to a data processing unit via precision sensors. The data processing unit can receive the readings of the balances in real time and calculate the difference between the readings of the balances on both sides to evaluate the pain level of the rabbit's lower limbs.

[0022] The surface of the balance tray 4 is provided with anti-skid patterns to increase the friction between the balance tray 4 and the rabbit's limbs to prevent the rabbit from sliding or falling during the experiment. The instrument also includes a display screen for displaying the balance readings and data processing results, which is connected to the data processing unit and can display the pain assessment results of the rabbit's lower limbs in real time.

[0023] Support feet with adjustable height are arranged under the base plate 1 , and the height of the support feet can be adjusted by a knob so as to adjust the overall height of the instrument according to experimental requirements.

[0024] In summary, the actual working principle of the present invention is that the operator places the rabbit that needs to be evaluated for pain between the limiting components. Due to the enclosure effect of the limiting components, the rabbit can stand stably on the support plate 5. When pain occurs in one lower limb, the rabbit will instinctively contract the limb on that side to relieve the pain. This contraction behavior will cause the pressure on the balance tray 4 corresponding to the limb on that side to decrease, and the balance reading will decrease accordingly. If the pain is severe, there may even be a situation where the balance has no reading. At the same time, almost all of the weight of the rabbit falls on the balance tray 4 on the other side, which significantly increases the reading of the balance on that side; by observing the readings of the two balances and the changes in the readings, the operator can accurately determine which side of the rabbit's lower limb is in pain. This evaluation method is not only fast and intuitive, but also has high accuracy.

[0025] In summary, the rabbit lower limb pain assessment instrument of the present invention realizes effective assessment of the rabbit lower limb pain degree by utilizing the precise measurement function of the balance system and combining the stable support function of the limit assembly. The instrument not only has the characteristics of simple structure and convenient operation, but also has accurate and reliable assessment results, providing a powerful tool support for pain research.
