A craniocerebral trauma model system under the action of bullet impact or shock wave

Abstract

The invention discloses a craniocerebral trauma model system under the action of bullet impact or shock wave. The adopted technical scheme is that the model used in the invention includes the preparation of a cranial brain model and is applied to the injury of the brain under the action of bullet impact or shock wave. analyze. The brain model includes the basic structures of the scalp, skull, brain tissue, and cerebrospinal fluid. At the same time, the model is implanted with brain tissue acceleration sensors, intracranial pressure sensors, and skull stress and strain sensors. The sensor is connected to the data acquisition module through the data line in the sensor connection base, and is processed by the data processing module and sent to the data evaluation module. The craniocerebral trauma model can be used in the field of protective equipment effectiveness evaluation, to quantify the protective effectiveness of protective equipment, and to conduct research on human head injury and protection from the perspective of simulating human mechanical indicators. It makes up for the deficiency of biological experiments, and improves the reliability of data close to real people.

Description

technical field [0001] The invention relates to the technical field of trauma models, in particular to a craniocerebral trauma model system under the impact of bullets or shock waves. Background technique [0002] With the widespread use of modern high-energy weapons and explosive devices, bulletproof helmets impacted by high-speed projectiles / explosive fragments will cause BFD (back face deformation) on the back of the helmet without penetration, and the impact kinetic energy will exert a short-term, short-term impact on the brain. The high-velocity, low-mass impact loads and shock waves are transmitted to the brain through the back of the helmet to cause non-penetrating injuries. Due to ethical constraints, it is not possible to conduct a large number of cadaver experiments for research on traumatic brain injury under high load. With the increasing maturity of 3D printing technology and the continuous development of sensors, physical models can be widely used in research....
