PAPR Shroud & Cuff
The PAPR shroud and cuff are two important consumables of the PAPR system, and both are in critically short supplies. The shroud functions as a hood to provide an additional seal from the PAPR helmet’s head and neck region to the user’s chest from splashes. It is made of DuPont Tyvek, a flashspun high-density polyethylene fiber that is both lightweight and highly durable. The cuff provides a tight seal by stretching a flexible polymer sheet to adapt the user’s head and neck. For this application, our design team has tested various iterations with clinicians and will ultimately provide multiple cuff material options in anticipation for supply chain disruptions. All tested options provide adequate seal, and much more resistance to mechanical failure than the manufacturer’s original materials.
