2.3.3 Operation of EOVE-70 SMD module
The operation of the EOVE-70 secretion management device is based on a closed control loop of the
proximal pressure. There are two distribution mode, automatic and manual. In both modes, a pressure
set point is send to the main actuator, the turbine. This pressure set point affectsdirectly turbine speed
which is proportional to pressure evolution. A high pressure set point will increase the turbine speed.
This pressure is measured by the proximal pressure sensor. Thus, the determination of distribution
parameters, especially the flow ramp rate affects the level of the turbine acceleration at the start of
each phase of respiratory cycle.
At the same time, the two solenoid valves control the four valves to manage phases of respiratory
cycles. A solenoid valve controls two valves during inhalation phase and the other one, the two others
during exhalation phase.
The measurement of inspiratory flow completes the system to calculate the peak flow and the tidal
volume on each respiratory cycle.
NOTE: When the EOVE-70 SMD is switched on but the ventilation is off, the turbine stills operate to
remain cool. There are two speeds for cooling during standby. Below 45°C the turbine speed is low,
and above the temperature threshold, the speed is higher. That is why there is always a low ambient
noise when the device is on.

Technical Manual –EOVE-70 MANAGEMENT
18
Operation of EOVE-70 SMD during inspiratory phase
During inspiratory phase, the EOVE-70 secretion management device provides positive pressure to the
patient. This pressure value depends on the set point configurated by the user and is proportional to
the turbine speed.
The air is inhaled through valve 1, and flows toward the turbine, then the valve 3 and the inspiratory
flow sensor.
During inspiratory phase, the low pressure (blue circuit on the drawing below) is equal to the
atmospheric pressure. The high pressure (orange circuit)provided by the turbine is equal to the
proximal pressure received by the patient. The difference of pressure between the two circuits is
positive.
Meanwhile, the pump enables to provide additional pressure to the two solenoid valves to control the
four valves. The solenoid valve A switches on to close valve 2 and valve 4. The solenoid valve B is turned
off, so the valves 1 and 3 are opened to permit the air to flow toward the patient.

Technical Manual –EOVE-70 MANAGEMENT
19
Operation of EOVE-70 SMD during expiratory phase
During the expiratory phase, the EOVE-70 secretion management device creates a suction to assist the
patient when he coughs. The air flows through the inspiratory flow sensor, the valve 4, then the turbine
and is exhaled by the valve 2.
During the expiratory phase, the low pressure is equal to the proximal pressure and the high pressure
is equal to atmospheric pressure. The difference of pressure between the two circuits is negative.

Technical Manual –EOVE-70 MANAGEMENT
20
The pump still provides additional pressure to the two solenoid valves to control the four valves.
However, during the expiratory phase, the solenoid valve B turns on to close the valve 1 and the valve
3 and the solenoid valve A switches off to open the valve 4 and the valve 2 to permit the exhalation.
