Technical description
The Elisée 350 is a volumetric and barometric ventilator. The air flow is generated by a turbine
from ambient air flowing through the air inlet. The Elisée 350 can therefore operate without a
pressurised air supply. Closed-loop control between the turbine and a valve allows the pressure
and the volume of air delivered to the patient to be monitored accurately.
An oxygen port enables the enrichment of the insufflated air up to an FiO
The ventilator body consists of a printed circuit board and a pressurised air assembly connected
to a turbine.
Printed circuit board
Controls the operation of the ventilator through the main microcontroller. The main
microcontroller controls:
•
Power supply switching
•
Ventilation measurements and controls
•
Temperature measurements of the ambient air, insufflated air and internal battery
•
The alarms
•
The user interfaces.
A second microcontroller monitors the activity of the main microcontroller.
Pressurised air assembly
The pressurised air assembly consists of:
•
A main turbine for ventilation
•
A PEEP microturbine to maintain positive end expiratory pressure
•
A rotary slide valve providing closed-loop control of flow rates and pressures
•
An I/E solenoid valve which controls the inspiratory and expiratory phases
•
A spontaneous inspiration valve
•
An electromagnet dedicated to the P0.1 function
•
Solenoid valves dedicated to cleaning the double circuit support
•
A regulator monitored by a proportional solenoid valve which controls the high-pressure
oxygen flow.
