Jet ventilator control system
First Claim
Patent Images
1. A control system for a jet ventilator having means for controllably providing jet ventilation gas pulses to a patient, the control system comprising:
- means for producing periodic pulses;
pulse-duration means for adjusting duration of the periodic pulses within the period thereof;
pulse-delay means for adjusting delay of the periodic pulses within and proportionally to the period thereof; and
control means responsive to the duration and delay adjusted pulses for correspondingly controlling the means for controllably providing the jet ventilation gas pulses to the patient.

Abstract
A jet ventilator control system produces a periodic pulse signal either asynchronous or synchronous with a patient'"'"'s pulse rate. It is proportional in frequency to the number of jet ventilation pulses to be applied to the patient per unit time and is digitally programmable to adjust the delay and duty cycle of the pulse signal within the period defined by the produced pulse. The duration and duty cycle adjusted pulse signals effect the application of jet ventilation pulses corresponding thereto to the patient.
