- Abstract
- Head trauma model is important and essential to development of new therapeutic modality. We present a upgraded head trauma model for experimental animals. Methods：Using pneumatic cylinder, solenoid valve, linear variable differential transformer(LVDT) and load cell, we developed "Chung-Ang University Hospital Model 1.0(CAUH-1)" based on controlled cortical impact model. Results：Changing pressure, impact velocity could be controlled up to 4m/sec. Using solenoid valve, we could control dwell time precisely. Real time impact force could be measured with load cell. Conclusion：Controlling dwell time, impact velocity, depth of deformation, this model would reproduce variable degrees of head injury. This model is so precise and versatile that it would be useful in diverse animal experimental researches. Key words:Upgraded cortical impact model;Impact velocity;Pneumatic cylinder.
