MESH Simple Shield

MESH Simple Shield (creation date 3/23/2020). See Disclaimer below.

The MESH Simple Shield was created by Marc Succi, MD and Holly Brideau, MD in the Department of Radiology at Mass General Hospital. It is a low-tech, low-cost and disposable shield to solve a simple need – face shield protective equipment during the shortfall of personal protective equipment (PPE) amongst the COVID-19 pandemic.

Key elements:

Machine-Free: No 3D printing/lasercutting/die casting etc. No tools. Anyone can assemble.
Low-Cost: 23 cents/unit off the shelf, significantly lower in bulk.
Fast: 15 second “manufacturing” (assembly) time. Pre-assemble and ship or assemble at point of care.
Disposable: Just like current PPE, this is disposable. No concerns about re-usability such as sanitation, handling, costs, etc.
Supply Chain: Because these materials are not in the current PPE supply chain, they are abundantly available.

Materials:

1. Adhesive foam weatherstripping (1 inch or thickest available – Amazon, Home Depot)
2. 8.5 x 11 standard clear acetate binder cover (Amazon, Staples)
3. Roll gauze or self-adhesive elastic bandage (3M Coban or generic – any first aid kit, hospital supply, Amazon, etc)

Assembly (15 seconds):

1) Single hole punch in both ends of the binder cover (arrange in “landscape mode”)
2) Tear and place foam weatherstripping along wide edge, in line with holes.
3) Roll gauze/self-adhesive bandage (easy to tear, no scissors) – Stuff through the two holes to create headband – tension keeps band in place.

Need to adjust size? The elastic nature of the band should have you covered. If not, simply pull more of the roll/gauze/bandage through either hole, and it will maintain it’s position via tension. No tools or fasteners needed.
