电子颅脑损伤仪(ecc

电子大脑皮质挫伤撞击仪( electric Cortical Contusion Impactor)主要针对脑皮质挫伤模型是神经损伤研究

机构最受欢迎的损伤模型制作工具。动物平台可以和驽种立体定位仪掊配使用。

由vCU大学设计制作的电子大脑皮质挫伤撞击仪,主要针对脑皮质挫伤模型。其组件有:坚固的铝架

物平台、撞击控制器和撞击头。动物平台可以和督种立体定位仪掊配使用。由高级线性马达驱动的撞击

可以由控制器来控制撞击参数,实现不同程度的损伤。撞击头含有感应器,可以确定谏率、撞击深度

与传統 Feeney's自由落体硬膜外撞击方法相比有以下优点可精确连续地控制撞击速度并获得实际撞击深

度和停留时间等参数而非重量差异很大的撞击。可精确重复制作挫伤损伤模型减少动物死亡,使实验过程

更加直观,可控

Celectric Cortical Contusion Impactor

The eccl is constructed with a sturdy aluminum frame to maximize rigidity, thereby ensuring impact

accuracy. The support base, animal platform and impactor head are anodized to prevent oxidation and

assure equipment longevity

Product assembly includes the base and support frame, and adjustable animal positioner with an

aluminum animal platform to be used in conjunction with a variety of stereotactic mounts. This model

utilizes the enhanced linier motor driven impactor and controller. The enhanced impact head also houses

a photo-optic sensor to determine velocity, impact depth and dwell, and is extremely reproducible.

Depending on the cell type, the degree of injury and the culture conditions, the injured cells may die

epair. Therefore, the system can be employed to study the responses to trauma, including cell injury

epair, death or pharmacologic intervention

The CIC ll has been designed for use with a patented, commercially available tissue culture system from

Flexcell Intemational Corp in Hillsborough, N.C. Tissue cultures are grown in culturing wells with

stretchable Silastic membrane bottoms. The CIC ll regulates the flow of compressed gas to rapidly

pressurize individual culture wells, causing a radial stretch injury to the culture. Injury severity is

ermined by controlling t

gas in and out of the sealed culture well and the peak pressure

captured to provide an accurate indicator of radial stretch

The CIC ll accepts both the Flex l@ 29.45cm2 culturing trays, which were used with the earlier CIC

Model 94A, and the BioFlex@e 57.75cm2 culturing trays
