Embodiment 1

[0028] The device for establishing the rat spinal cord blast injury model in this example is as follows: figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 with Figure 7 As shown, the base plate 1, the pillar 2 fixed on the base plate 1, the explosion source pole 3 installed on the pillar 2 through the fixing clip 14, the animal box installed on the pillar 2 through the fixing clip 14 and the animal box pole 4 5. There is a groove 7 on the bottom plate 1, a gap 8 is opened in the groove 7, and a sensor probe is placed at the bottom of the gap 8, which is used to record the explosion shock wave value; The groove 7 and the gap 8.

[0029] A gap width adjusting piece 9 is arranged in the groove 7, a gap length adjusting piece 10 is installed on the bottom plate 1 and the box bottom 15, and a fixing strip 11 is arranged on the bottom plate 1 and the box bottom 15 for fixing the gap width adjusting piece 9 and the gap length The adjusting piece 10 and the fi...

Embodiment 2

[0033] The apparatus for establishing the rat spinal cord blast injury model in this example is the same as that in Embodiment 1 except that there is no gap width adjustment sheet 9, gap length adjustment sheet 10, fixing strip 11 and fixing screw 12.

Abstract

The invention relates to a device for building of a rat spinal cord explosion injury model in the field of medical experiment devices. The device comprises a bottom plate (1), a supporting column (2) fixed on the bottom plate (1), an explosion source supporting rod (3) arranged on the supporting column (2) and an animal box (5) arranged on the supporting column (2) through an animal box supporting rod (4). The bottom plate (1) is provided with grooves (7), a seam (8) is formed in the grooves (7), the bottom of the seam (8) is provided with a sensor probe, and the box bottom (15) of the animal box (5) is provided with grooves (7) and a seam (8) which corresponding to those of the bottom plate (1). The device overcomes the defects that an existing spinal cord explosion injury model can not achieve precise explosion of a target portion and is poor in experiment accuracy and control property. The device for the building of the rat spinal cord explosion injury model is simple to operate, good in practical control, and capable of achieving the precise explosion of an injury of the target portion.

Description

technical field [0001] The invention relates to the field of medical experiment devices, in particular to a device for establishing a rat spinal cord blast injury model. Background technique [0002] At present, there are many modeling methods in the field of animal experiments to establish spinal cord blast injury models, but there are not many methods that directly use explosives to generate shock waves to damage the spinal cord to simulate explosions in real military and life, and most modeling devices cannot To achieve precise blasting at the target site, it is impossible to achieve good control of the shock wave equivalent. Due to the uncontrollable blasting window, the resulting explosion is rough, often accompanied by damage to other parts of the tissue, which interferes with the experiment and even draws unreliable conclusions. Most devices The anatomical and physiological characteristics of the experimental animals are not considered, and the accuracy and overall co...
