We have a bench-top prototype that's fully operational, running with a commercial test lung. It demonstrates our sensor and valving technology works. Also, the airway can be simply and quickly removed.
The airway contains any and all of the air that might come from a patient: it never touches the base unit. The airway is removed in one piece and replaced easily. In a matter of seconds, the ventilator is sterile.
The key to making a disposable airway work at reasonable cost is the innovation in our patent-pending sensors and valves. The disposable contains no electronics, yet we can sense pressure and flow and adjust the flow.
The disposable airway is easy to change. It simply pops out, and a new one is put in its place. It can literally be changed in seconds.
We set out to drive down the cost of the ventilator as part of the design. We attacked the most expensive components in a vent: the valves and sensors. And the disposable is just plastic parts.
