Animal fragment injury device

Abstract

The invention relates to an animal fragment injury device, and belongs to the technical field of animal test devices. The animal fragment injury device comprises a base, a compression chamber, a fragment generator, a supercharger and a protective cover, wherein the compression chamber is a closed shell, and openings are formed in the two ends of the shell; the fragment generator comprises an energy accumulation pipe and a fragment generation mechanism, and the fragment generation mechanism comprises a cover body, a sheet and a plurality of fragments; the supercharger is a high-pressure air compressor; the sheet is provided with cracks; and the protective cover at least comprises a framework layer, a heat absorption layer stacked outside the framework layer and an energy absorption layer arranged outside the heat absorption layer in a sealed mode, and the energy absorption layer is a membrane made of elastic materials. According to the animal fragment injury device, the air pressure mode is used for replacing a traditional mode that fragments are generated by means of shell explosion, safety is remarkably improved, cost is remarkably reduced, pressure is released at the moment whenworking pressure is reached, namely that high pressure and release are completed at the same time, and the requirement for equipment is lowered.

Description

technical field [0001] The invention relates to the technical field of animal test devices, in particular to a device for instantaneously injuring experimental animals by fragments. Background technique [0002] On the battlefield, splinter injuries usually refer to projectile injuries caused by accelerated throwing of bullets and shell fragments and hitting the human body. This type of injury directly affects the human body, with strong force and great damage, and is an important topic of battlefield rescue. In the scientific research on this type of injury, the human body is not directly used for research. Without exception, similar research is first carried out on animals and then extended to the human body. Relatively satisfactory results can often be obtained through this kind of research on life-like organisms. [0003] However, the existing technology does not propose a good method for the generation of fragments. Instead, a real shell explosion is used to carry out ...
