Vertical striking device for traumatic brain injury of large animals

Abstract

The invention discloses a vertical striking device for traumatic brain injury of large animals. The vertical striking device comprises a sewage collection box, the sewage collection box facilitates collection of sewage in the experiment process, a mesh plate is arranged on the upper surface of the sewage collection box, the sewage can quickly enter the sewage collection box through the mesh plate, the mesh plate is fixedly connected with the sewage collection box through a stud with a head, the mesh plate is convenient to detach through the stud with the head. The device is stable in structure, simple to operate and capable of being repeatedly operated; an animal head sample clamp is easy and convenient to use and high in impact precision, impact force directly acts on the meninx of an animal model, skull fragments are avoided, the experiment precision is effectively improved, dirty liquid collection in the experiment process is facilitated due to the arrangement of the sewage collection box, the mesh plate is arranged, so that the sewage can quickly enter the sewage collection box.

Description

technical field [0001] The invention relates to the technical field of rodent models for simulating traumatic brain injury, in particular to a vertical striking device for large animal traumatic brain injury. Background technique [0002] As we all know, head injuries have a high fatality rate, and head injuries often occur in situations of traffic accidents, falling objects, falls, falls from heights, and beatings. In the process of research on the protection of the human head, it is often necessary to obtain data such as injury criteria and mechanical responses of head injuries. Doing experiments under specific working conditions is a very effective way to obtain data. Of course, we cannot achieve trauma experiments on human heads, but it is a good way to use animal head samples such as pigs and dogs as substitutes. [0003] In the prior art, a free-fall brain injury model striker is usually used to simulate blows on the animal's head. Currently, the free-fall brain inju...

Problems solved by technology

The diameter of the striker is 4.5mm, the height is 20mm, the weight of the striker is 40g and 20g, and the height of the metal sleeve is 30cm. The brain locator includes the bottom plate, the rat adapter, the rat ear rod, etc. Both strength and precision are difficult to control, and brain tissue damage is uneven

[0004] At the same time, the percussion device used in craniocerebral injury modeling in the prior art directly acts on the skull of the animal head during use. During the percussion process, more bone fragments will be generated, and these bone fragments should be cleaned. It is very inconvenient, and bone fragments can easily damage the model during cleaning
