Abstract

A ventilator device for artificial ventilation use in infant and pediatric wards, and which may be adapted for use with adult patients as well. The ventilator device comprises a pressure control system having at least two parallel connected exhalation valves, a pressure monitoring system having bar display, optical sensors attached to the bar display, and an alarm system with a 'no break' system including a rechargeable battery. One of the exhalation valves is connected at the beginning of the inspiratory airway and this valve is coupled with a moisturizing system. An inspiratory tube connected to the moisturizing system is connected to one branch of a 'Y' connector where the other branch of the 'Y' connector is connected to an expiratory tube leading to the other exhalation valve at the end of the expiratory airway. These exhalation valves are controlled by electronic control modules and pneumatic control through 3-way 2-position solenoid valves. These devices are capable of controlling pressure, controlling inspiratory and expiratory times, and regulating and monitoring the ratio between the inspiratory and the expiratory times. The ventilator is particularly effective in that it is capable of controlling pressure in the event of an obstruction which often increases the pressure above a safe limit, thus possibly resulting in rupturing of the lungs. The device is capable of providing a continuous flow with timed cycles and pressure control in order to guard against a sudden increase or decrease of pressure in the ventilator.
