Description

A device for raising reptile models in an upright state

technical field

The invention belongs to the field of animal feeding devices, in particular to a fixing device for fixing crawling experimental animals to move freely in an upright state.

Background technique

Intervertebral disc degeneration (IVDD) is the premise and basic pathological process of a series of spinal degenerative diseases. Clinically, it often manifests as neck and shoulder pain, waist and leg pain and other symptoms. produce a series of corresponding symptoms. At present, the etiology and pathogenesis of IVDD have not been fully elucidated. Through the study of animal models of intervertebral disc degeneration, establishing a reliable animal model can provide a good research object and experimental carrier for the study of the etiology and pathogenesis of IVDD. Although, many studies have established animal models of intervertebral disc degeneration through various methods, including: animal models of spontaneous intervertebral disc degeneration, animal models of intervertebral disc degeneration caused by stress changes, spinal instability-induced intervertebral disc degeneration models, and chemical methods. Animal models, animal models prepared by gene modification or knockout, and surgical injury animal models, etc., but so far, there is still no recognized and reliable modeling method that has been widely used.

At present, the more common animal species used to construct animal models of intervertebral disc degeneration include mice, rabbits, sheep, dogs, and pigs. These species have a common feature that they are all reptiles, and the physiological structure of their spine is completely opposite to that of upright humans. After the animal model is established, its crawling life habits are an important factor affecting the experimental results; in addition, monkeys and baboons, which are closely related to humans, are also ideal model animals. They can walk upright on two feet, have a spine structure similar to humans, The biomechanical factors carried by the spine are similar, so it is the most authentic and reliable to establish animal models of monkey intervertebral disc degeneration to study the pathological process of human intervertebral disc degeneration. This limits its application as a model animal.

Based on the above reasons, the following points should be met in the selection and preparation of animal models of intervertebral disc degeneration: (1) The process of model animal and human intervertebral disc degeneration is similar and comparable; (2) Has good repeatability ; (3) It is easy to operate and economical. Therefore, if reptiles can be changed into upright living habits, then such experimental animals will become our primary choice for establishing animal models of intervertebral disc degeneration. However, large mammals such as pigs, dogs, and sheep have the disadvantages of being expensive and inconvenient to raise, so these animals have not been widely used to prepare animal models of intervertebral disc degeneration; and are currently widely used in the experimental research of IVDD to prepare intervertebral discs. The experimental animals of the degeneration animal model are rats and rabbits.

In order to overcome the defects in the anatomical structure and biomechanics of these two animals, some scholars use artificial methods to force them to stand up, such as amputating the upper limbs of rats to establish a biped animal model; Maintain an upright position and apply longitudinal pressure to establish an animal model. By adopting corresponding measures to establish an upright animal model, the diseased intervertebral disc can withstand the stimulation of mechanical factors to further study its pathological occurrence and development mechanism. However, this method is cruel to experimental animals and is not conducive to promotion.

Further, the fixed cylinder is made of a PVC pipe with a diameter equal to that of the reptile’s torso, assembled from two arc-shaped blades, and the PVC pipe is equipped with a hinge at half the pipe diameter, which is convenient for opening and closing for crawling Keep the animal in an upright position.

Further, the moving cylinder is assembled from four arc-shaped blades, and an adjustment knob mechanism is installed between the gaps between the two blades, and the gap distance is adjusted by adjusting the knob to achieve the effect of adjusting the diameter of the moving cylinder. The moving cylinder is connected with the longitudinal and transverse slideways, and by adjusting the diameter of the moving cylinder, it can accommodate the fixed cylinder, thereby realizing the 360° rotation between the fixed cylinder and the moving cylinder.

Further, there are lifting adjustment knobs on the drinking cylinder and feeding cylinder fixed on the overall device, and the lifting and rotating can adjust the height of the drinking cylinder to facilitate the feeding of animals of different heights, or to grow with the body of reptiles And adjust its height, guarantee the normal eating, drinking water of reptile.

In another preferred embodiment, the fixed cylinder can make the reptile in an upright state through the switch of the hinge, and the inner diameter of the fixed cylinder should be equivalent to the trunk diameter of the reptile, so that the fixed cylinder can The inner diameter will not cause damage to the reptile torso.

In another preferred embodiment, the four adjustment knobs around the moving cylinder can ensure that the diameter of the moving cylinder is slightly larger than that of the fixed cylinder and there is a proper gap, so that the distance between the fixed cylinder and the moving cylinder is 360°. ° Rotation activity. In addition, there are slip rings on both sides of the moving cylinder to connect the transverse slideways, so that the fixed cylinder and the moving cylinder can move left and right as a whole. Moreover, there are slip rings at both ends of the transverse slideway to connect the longitudinal slideway, so that the fixed cylinder, the moving cylinder and the transverse slideway can move forward and backward as a whole.

Further, the longitudinal slideway is fixed on the two side walls of the breeding cage through adjustment knobs, and the overall height of the moving cylinder, the containment and fixing cylinder, the connecting horizontal slideway and the longitudinal slideway can be adjusted according to the growth rate of the reptile.

The present invention has following beneficial effect:

(1) The rearing device makes the reptiles stand in an upright state, overcomes the defects of reptiles in anatomical structure and biomechanics, and makes the erect animal models established by relevant experimental researches more in line with the experimental requirements. For example, the animal model of intervertebral disc degeneration can enable the diseased intervertebral disc to withstand the stimulation of mechanical factors and further study its pathological occurrence and development mechanism.

(2) Reptiles can achieve 360° rotation and all-round movement forward, backward, left and right with the help of fixed cylinder, moving cylinder, horizontal slideway and longitudinal slideway, which makes the established animal model closer to the biomechanical mechanism of Mechanical bearing mechanisms of the human spine.

(3) The breeding device can not only be used for the reptile model in an upright state required for related experiments, but also can increase the autonomous activities of reptiles and minimize the damage to experimental animals.
