亲水性多孔材料作为头盔衬垫预防创伤性脑损伤的研究
Hydrophilic Porous Materials as Helmet Padding Able to Prevent Traumatic Brain Injuries
摘要:
由于他/她的头盔与表面或另一运动员的碰撞,参与诸如足球或曲棍球的碰撞运动的运动员的头部的平均减速度的最小可能值与头盔衬垫厚度成反比。由于其最大厚度存在实际限制,因此难以显著降低平均加速度。然而,有证据表明,峰值加速度而不是平均加速度是脑损伤的最重要原因。这里提出,由于撞击而发生的脑损伤可以通过使用用流体溶胀的亲水性多孔材料作为衬垫来减少。当流体在冲击中被挤出多孔材料时所经历的摩擦可以“调整”颅骨的加速度,使得其在冲击期间不会显著高于其平均值。
英文摘要:
The minimum possible value of the average deceleration of the head of a player engaged in an impact sport such as football or hockey, as a result of an impact of his/her helmet with a surface or another player, is inversely proportional to the helmet padding thickness. Since there are practical limits to its maximum thickness, it is difficult to significantly reduce the average acceleration. There is evidence, however, that the peak, rather than the average, acceleration is the most significant cause of brain injury. It is proposed here that brain injuries that occur as a result of an impact, could be reduced by using as padding a hydrophilic porous material swollen with fluid. The friction experienced by the fluid as it is squeezed out of the porous material in an impact can "tune" the acceleration of the skull so that it is never significantly higher than its average during the impact.
