Flow Power

The proposed ventilator does not require a mechanical pump. It uses the pipeline pressure of the medical ‎facility and regulates this pressure in order to deliver ventilations with certain Peak Inspiratory Pressure. ‎No mechanical pump, would facilitate the production, reduces the costs, reduces the failures and ‎maintenance requirements of the ventilator. ‎ The Ventilation Rate and I:E Ratio would be adjusted by a controller unit actuating the solenoid valves. The ‎cylinder provides a "reservoir" of Air/O2 mixture for SIMV mode (i.e. if patient takes a spontaneous breath ‎there is a ready-to-deliver mixture of Air/O2). ‎ A Hall Effect Sensor Position Measurement Device is attached to the cylinder and there is a magnet on the ‎piston. Movement of the piston, changes the position of the magnet in relation to the Hall Effect Sensor ‎Position Measurement Device. This allows said controller unit to determine the position of the piston, thus ‎adjusting the tidal volume delivered to the patient by actuating the solenoid valves. ‎ Details of the controller unit and its connections to the element of the proposed ventilator are not ‎illustrated at this stage so as not to obscure the main features. ‎
