Abstract

The invention discloses a craniocerebral trauma model system under the action of bullet impact or shock waves. According to the adopted the technical scheme, the model used in the craniocerebral trauma model system comprises preparation of a craniocerebral model and is applied to analysis of craniocerebral trauma conditions under the action of bullet impact or shock waves. The craniocerebral modelcomprises basic structures of scalp, skull, brain tissue and cerebrospinal fluid, and meanwhile, a brain tissue acceleration sensor, an intracranial pressure sensor and a skull stress strain sensor are implanted in the model. The sensors are connected with a data acquisition module through data lines in sensor connecting bases and data is transmitted to a data evaluation module after being processed by a data processing module. The craniocerebral trauma model can be used in the field of effectiveness evaluation of protection equipment, quantifies the protection effectiveness of the protectionequipment, and can carry out research on the injury and protection of the human head from the view point of simulating human mechanical indexes. The defects of biological tests are overcome, and thecredibility of data approaching a real person is improved.

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....
