Device for manufacturing craniocerebral explosion injury models for small animals

Abstract

The invention discloses a device for manufacturing craniocerebral explosion injury models for small animals, which comprises a supporting plate, four upright posts arranged on the surface of the supporting plate, longitudinal guide rails, longitudinal sliding blocks, transverse guide rails, transverse sliding blocks, a vertical sliding block and a charging cabin, wherein the longitudinal guide rails are arranged at the top ends of the two upright posts adjacent with each other on the longitudinal direction; the longitudinal sliding block is movably arranged on each longitudinal guide rail; the two transverse guide rails are fixedly arranged between the two longitudinal guide rails; the vertical sliding block is arranged between the two transverse guide rails; the charging cabin is arranged in the vertical sliding block; and the bottom end of the charging cabin penetrates through the bottom surface of the vertical sliding block. Controllable precise explosion on any specific part of a testing animal can be realized through the free adjustment in the longitudinal, transverse and vertical directions so as to obtain the animal explosion injury model through shock waves.

Description

Technical field: [0001] The invention relates to a device for making a small animal craniocerebral injury model, in particular to a device for making a blast injury model for research on the mechanism of blast injury and related treatment methods. Background technique: [0002] At present, in the field of animal model production of small animal models of craniocerebral blast injury, there are already a variety of model production methods. However, there are not many ways to directly use explosive blasting to make models, and none of the existing methods can achieve controllable and precise blasting of explosives at any specific part of the experimental animal, and it is impossible to use shock waves to cause accurate and repeatable animal explosions. damage model. Invention content: [0003] The invention discloses a device for making a craniocerebral injury model of a small animal. An appropriate amount of explosives is pressed and filled in a charge chamber of a vertica...
