摘要： The time duration of the inflation and deflation cycles for a syringe assembly for an inflation system are measured and displayed. An inflation cycle is initiated when a increase-pressure switch is depressed. A timer will begin timing the inflation cycle when the increase-pressure switch is released and a predetermined initial pressure is detected in a tube of the syringe assembly. A deflation cycle is initiated when a decrease-pressure switch is depressed. The timer will stop measuring the inflation cycle and then begin timing the deflation cycle when the decrease-pressure switch is released and a predetermined neutral pressure is detected in a tube of the syringe assembly. Rapid deflation can be achieved by depressing a rapid-decrease-pressure switch. Upon actuation of the rapid-decrease-pressure switch, the timer immediately stops measuring the inflation cycle and begins timing the deflation cycle.

摘要翻译： 测量和显示用于充气系统的注射器组件的充气和通气周期的持续时间。 当按压增压开关时，启动充气循环。 当释放升压开关并且在注射器组件的管中检测到预定的初始压力时，定时器将开始定时充气循环。 当降压开关被按下时，启动放气循环。 定时器将停止测量充气循环，然后当降低压力开关被释放并且在注射器组件的管中检测到预定的中性压力时开始计时放气循环。 通过按下快速减压开关即可实现快速放气。 在启动快速减压开关时，定时器立即停止测量充气循环，并开始计时放气循环。
