瞳孔的大小是由虹膜内瞳孔肌的活动所决定的,瞳孔肌接受植物神经系统的调节控制,副交感神经兴奋,瞳孔括约肌收缩,瞳孔直径缩小,交感神经兴奋,瞳孔扩大肌收缩,瞪孔直径扩大,故瞳孔的动态变化可反映植物神经系统和大脑皮层的功能状态。基础和临床医学往往都以瞳孔大小的变化作为判断中枢神经系统机能状态的参考指标之一。以往用瞳孔定标孔肉眼观察和标定瞳孔大小,不能做客观的直接记录并难以进行精确的定量分析。本组研制成电脑控制的TK-1型瞳孔测试仪,采用红外光闭路电视技术,可
The size of the pupil is determined by the activity of the pupil muscle in the iris. The pupil muscle is regulated by the autonomic nervous system. The parasympathetic nerve is excited. The pupil sphincter is constricted. The pupil diameter is reduced. Sympathetic excitement. The pupil is enlarged. Muscle diameter is increased. , So the dynamic changes of the pupil can reflect the functional status of the autonomic nervous system and cerebral cortex. Fundamentals and clinical medicine often use the change of pupil size as one of the reference indexes for judging the functional status of the central nervous system. In the past with the pupil calibration hole naked eye observation and calibration of pupil size, can not be objective and direct record and difficult to carry out accurate quantitative analysis. The group developed a computer-controlled TK-1-type pupil tester, the use of infrared light closed-circuit television technology,
