| 目的：研制一种在正加速度作用下能实时观测大鼠行为状态的实验视频采集装置，为研究正加速度导致脑损伤的病理生理
机制和防治措施提供新的方法。方法：依据正加速度对大鼠体位的要求和离心机特殊的环境，通过特制的大鼠座舱和无线视频采
集单元来实现对动物离心机中正加速度作用下大鼠行为状态的实时观测；固定大鼠的座舱主要由胸部固定圈、身长调节圈、头部
运动限制框构成；无线视频采集单元由2.4 G 无线摄像头、无线信号接收器、信号放大器、计算机以及视频采集软件组成。结果：座
舱特殊的大鼠固定方式，既满足了正加速度对体位的要求，又不影响对大鼠行为状态的观测，2.4 G 无线视频采集技术保证视频
信号在离心机高速旋转环境下的实时传输和观测，视频画面清晰流畅，并且能保存视频供回放分析。结论：动物离心机无线视频
采集装置可用于正加速度作用下大鼠行为状态的实时观测与研究。 |

| Objective: To develop a kind of experimental video recording device to instantly observe rats behavior under positive
acceleration, provide the new methods to study the pathophysiological mechanisms of brain injury induced by positive acceleration as
well as for prevention and treatment brain injury. Methods: According to the requirement for rats body status under positive acceleration
and special environment of centrifuge machine, through specialized-made rats cabin and placement of wireless video recording device to
realize the instantly monitor of rats behavior under positive acceleration. Fixed rats cabin is made of chest fastening circle, body length
modulator and head fixed frame; while wireless video recording device is composed by 24G wireless video recorder, wireless signal
receiver, signal amplifier, computer and software for video signal collection. Results: The specialized fixed methods of rats cabin not only
satisfy the demand for body status under positive acceleration, but also not affect the observation of rats behavior. 24G wireless video
recording device guarantee transmission of video signal, provide the high quality-video pictures and video replaying for future analysis.
Conclusion: Wireless video recording device implemented on the high velocity animal centrifuge could instantly obverse and study the
rats behavior under positive acceleration. |
