Abstract

A physical head model and a test system are disclosed. The physical head model includes a skull model simulating a skull shape, a brain tissue model simulating a shape of brain tissue in the skull model, a meninges model used for wrapping the brain tissue model, a cerebrospinal fluid model used for filling a gap between the skull model and the meninges model and a skin model used for wrapping theskull model; the brain tissue model is made of hydrogel. The physical head model provided in this embodiment truly reflects a physiological structure of a head; via combination of the physical head model and a dynamic test system, research on related mechanisms such as craniocerebral injury and the like can be conducted, and biological protection performance of protective equipment such as helmetsand the like can be evaluated.

Description

technical field [0001] The invention relates to a physical head model, in particular to a physical head model and a testing system. Background technique [0002] It is a current research hotspot to study the damage mechanism of human cranial brain under the circumstances of collision and explosion. The current animal experiments and simple physical head models cannot truly reflect the dynamic response of the human brain under impact loads, while living experiments are against morality and ethics, and the number of samples for dead body experiments is small and the cost is too high. Therefore, it is particularly important to develop a high-fidelity physical head model. Contents of the invention [0003] At least one embodiment of the present invention provides a physical head model and testing system. [0004] One embodiment of the present invention provides a physical head model, including: a skull model simulating the shape of a skull, a brain tissue model located in th...
