During ambulatory monitoring, physiological signals and other parameters are measured and stored in a portable recorder. To optimise subsequent interpretation, additional information is provided by the subject pressing a button at the onset of any relevant symptoms or events, simultaneously noting these in a personal diary. To distinguish between different events, the subject is instructed to press the event button a specific number of times. Confusion arises when the subject fails to press the button correctly or to record the event accurately on paper. The device described overcomes these problems by providing the subject with separate switches on a single remote unit. Depending on the button pressed, the unit automatically sends a coded signal to the recorder, allowing unequivocal identification of events during data playback and analysis. Although primarily used in urodynamics, this simple device can be used in many other similar recording systems with little or no modification.
在动态监测期间，生理信号和其他参数被测量并存储在便携式记录器中。为了优化后续的解读，当任何相关症状或事件开始时，受试者按下一个按钮，同时在个人日记中记录这些情况，从而提供额外信息。为了区分不同的事件，受试者被指示按特定次数按下事件按钮。当受试者未能正确按下按钮或未在纸上准确记录事件时，就会产生混淆。所描述的设备通过在单个远程单元上为受试者提供单独的开关来克服这些问题。根据按下的按钮，该单元会自动向记录器发送编码信号，从而在数据回放和分析期间能够明确识别事件。尽管该设备主要用于尿动力学，但这个简单的设备几乎无需修改就可用于许多其他类似的记录系统。
