Animal blast injury experiment simulation tool

Abstract

The invention belongs to the field of animal experiments, provides an experiment mold which can control the strength of explosive shock waves and avoid interference factors, and particularly relates to an animal blast injury experiment simulation tool. The animal blast injury experiment simulation tool is easy and convenient to operate and more meets requirements of actual use. The main structure of the animal blast injury experiment simulation tool is made of stainless steel, wherein the selected thickness of the stainless steel ranges from 0.7cm to 1.0cm, the stainless steel can bear the pressure of 30MPa, the applicable temperature of the stainless steel ranges from -195DEG C to 850 DEG C, and the stainless steel is high in safety. A high pressure adjustment valve is arranged at the top end of an experiment animal containing cavity on the left and can control impact pressure borne by animals inside the cavity, wherein a low-pressure gear and a high-pressure gear are arranged on the high pressure adjustment valve. A middle filtering film is made of high-strength and high-permeability ceramic materials and NPC hole forming agents, the bending strength of the middle filtering film is 251MPa, and therefore the purpose of filtering blasting waste is achieved. Because a catalyst hole is formed, operation safety and blasting synchronization are improved. A left and right integrated sealing cover serves as a mold top cover, and silicone rubber sealing strips are embedded in the interior edge of the cover in an annular mode. The animal blast injury experiment simulation tool is easy to process and manufacture, low in cost, strong in practicability and wide in market prospect.

Description

Technical field [0001] The invention belongs to the field of animal experiments, and in particular relates to experimental equipment for explosion impact injuries. Background technique [0002] At present, local wars and terrorist attacks in the world mainly rely on explosive weapons. There are two main ways of causing injury by explosive weapons. One is that the fragments produced by the explosion directly act on the human body to cause damage; Thereby forming a kind of supersonic high-pressure wave acting on the damage produced by the human body, that is, shock wave injury. The damage caused by the shock wave directly acting on the human body is called blast injury. Thoracic trauma is the main cause of trauma and death in war, and the most common thoracic injuries are closed wounds, blast injuries, rather than traditional penetrating wounds, and the resulting deaths are higher. Due to the wide coverage of the shock wave, a large number of wounded can be generated in an ...

AI Technical Summary

Problems solved by technology

Although the experimental model of fragment injury caused by the shock wave composite bullet can meet the requirements of shock wave injury, it cannot truly simulate the injury characteristics of shock injury due to its complicated synchronous control: using a biological shock tube to cause shock injury, this method has The positioning is accurate and repeatable, but the impact injury is limited to a certain part or organ, which does not fully conform to the actual injury situation: the blast wave generated by the synchronous electric detonator explosion is used to simulate the explosion impact of explosive weapons to establish an impact injury model, which is consistent with the actual situation. The explosion injury parameters are very close, but the explosion parameters are not easy to determine, and the explosion energy is not easy to control
