Latest Patents

Dack holds a patent for a ventilator exhalation valve. This valve is designed to control the exhalation flow rate and pressure effectively. The invention features a free-floating diaphragm that is biased against a fixed valve seat in an inhalation configuration. This design prevents reverse flow through the valve. As forward flow passes through, the diaphragm separates from the valve seat, allowing for efficient operation. The mechanism includes a poppet affixed to a shaft with a ferromagnetic portion, which interacts with a linear actuator. This setup induces a current in a coil, providing feedback that enhances pressure stability.
