Health Equity and Quality Improvement (HEQI) Summit

What’s the Problem?

• Powered air-purifying respirators (PAPRs) are a type of Personal Protective Equipment (PPE) that serves an essential line of defense against the spread of COVID-19 and other airborne pathogens.
• Demand for PAPRs are at a premium during a time where supply chains have been disrupted.
• The hose component of the 3M™ Air-Mate™ PAPR has a fragile interface with the hood, leading to damage and rendering the PAPR unit unsafe for continued use.
• PAPR units are on backorder, as are their components.
• Given the acute need for functional PAPRs other approaches for repair were explored.

Repairing A Damaged Powered Air-Purifying Respirator (Papr) Battery Component Component With 3-D Printing, Robert Ries, Dante Varotsis, Michelle Ho, Kathryn Linder, Jordan Kurzum, Bon Ku, Md, Mpp, Matt Fields, Md, Robert Pugliese, Pharmd, Morgan Hutchinson, Md

Health Equity and Quality Improvement (HEQI) Summit

• A team from the Thomas Jefferson University Health Design Lab worked with local engineers at FKB to create a 3-D replacement model for the faulty component
• A new component was designed to function with existing battery components
• The new component was created using a desktop fused deposition modeling (FDM) 3-D printer with polylactic acid (PLA) filament

Safer Ambu-Bag Manual Ventilation Through Addition Of A Second High Efficiency Particulate Air (Hepa) Filter, Robert Ries, Morgan Hutchinson, Md, Robert Pugliese, Pharmd, Bon Ku, Md, Mpp, Matt Fields, Md

Health Equity and Quality Improvement (HEQI) Summit

• Experts from the Thomas Jefferson University Health Design Lab met with Emergency Medicine and Anesthesia physicians and local engineers
• A design was envisioned in which 3-D printed connectors could be created to add an additional HEPA Filter as shown in Figure 1
• STL Files for the adapters were created based on standard HEPA filter diameters and 3-D printed
• The second HEPA filter was easily assembled by novice users using the adapters
• Ventilation adequacy using the double HEPA filter ambu-bag was similar to single HEPA filtered ambu-bag ventilation based on observed inflation of a test lung
