Abstract
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.
