Description
A contusion device specifically designed for medical research using rats and mice.
PSI engineers developed a contusion device designed specifically for research using rats and mice. The system provides researchers specializing in spinal cord injuries with a unique tool to evaluate the mechanisms underlying injury to spinal cord structures.
This instrument enables the application of computer controlled standard-force injuries to the spinal cords of small rodents. Force levels are user-selectable between 30 and 300 kilodynes. The impact tip can also be halted to dwell at a specific force level to model extended compression injuries.
Real-time probe force and displacement graphs provide the operator with a precise detailed record of the kinematics of each impact. Combined with a Windows 10 PC, tip force and position are plotted as a function of time and displayed on the PC. The data can be recorded in a log file along with any other experiment parameters specified by the user. The experiment data and impact curves can be recalled to review experiments. The system is ready to use out of the box and requires minimal training to achieve precise, consistent impacts.
