Technology Description
Researchers in Mohamed Zayed’s lab at Washington University have developed a dynamic seal valve that creates a seal around devices with varying cross sections. This valve could be deployed in masks to protect health care workers from aerosol infection while using airway management tools.
The valve can be fully closed or collapsed to various diameters using the serrated interface mechanism. An outer jaw is twisted by the user while an inner jaw is held in place, with a flexible material between them creating the seal.
