A Design of High-Frequency Oscillatory Ventilator Using Phase Lock Loop system

Abstract

In this study, high frequency oscillatory ventilator was designed and constructed. Using designed by phase-lock loop system, in order to accurately and easily treat both the outlet volume and rpm. A system has been designed and is being evaluated using CD4046A PLL IC. We use this PLL IC for the purpose of motor controls. The device consists of PLL system, pumping mechanism, piston, cylinder, and special crank shaft are required. This system characteristics were as follows: 1) Frequency: 20-1800 rpm 2) Outlet air volume: 1-50 cc
