Device for creating rat spinal-cord blast injury model

Abstract

The invention relates to a device, for creating a rat spinal-cord blast injury model, in the field of medical experimental apparatus. The device comprises a baseplate (1), support columns (2), a blast source support rod (3) and an animal box (5). The support columns (2) are fixed on the baseplate (1), the blast source support rod (3) is mounted on the support columns (2), and the animal box (5) is mounted on the support columns (2) through an animal box support rod (4). A groove (7) is formed in the baseplate (1), and a gap (8) is formed in the groove (7). A sensor probe is arranged at the bottom of the gap (8). A groove (7) and a gap (8) corresponding to the baseplate (1) are formed in the box bottom (15) of the animal box (5). By the device, the defects that accurate blasting of target positions cannot be realized by existing spinal-cord blast injury models and experiment accuracy and overall controllability are poor are overcome; the device is simple to operate, good in actual control and capable of accurately controlling injuries of the target positions.

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...
