STRATEGY
Universal, reusable virus/bacteria inactivating respiratory devices
A-BaVi Protect Inc will develop respiratory protection equipment by using its unique antimicrobial technologies. In 2016, Dr. Choi (the founder) filed a patent on the salt recrystallization-based antimicrobial technology. His team at the University of Alberta has demonstrated that salt-coated filters can quickly inactivate different types of influenza virus (PR/34 H1N1, VN/04 H5N1, CA/09 H1N1) within 5-30 minutes upon contact, offering broad-spectrum protection. A-BaVi Protec will continue to develop new antimicrobial technologies, and apply them to commercialize universal and reusable, pathogen inactivating respiratory devices.



Respiratory disease transmission
-
Different-sized droplets/aerosols take a prominent role in transmission of respiratory diseases (airborne: aerosol size < 5µm). Depending on their size, the route of infection can be different.
-
To control respiratory diseases, two representative respiratory devices, surgical masks and respirators, have been employed to protect individuals against respiratory diseases.

Status of Current Technology
-
Current face masks are not designed for disinfection and reuse, and are recommended for single use only.
-
To date, limited scientific efforts have been focused on improving face masks to prevent transmission of droplet/airborne infectious diseases. Even lab-level approaches, such as use of antimicrobial metallic compounds or carbon-based materials cannot be employed in respiratory devices because of fundamental issues such as toxicity and scalability limits.



Pandemic Preparedness
-
Respiratory protection is crucial for pandemic/epidemic preparedness in the context of personal protection, healthcare systems, and governance.
-
Antimicrobial face masks permit the reuse of masks/respirators, increase protection for healthcare providers and the public against respiratory diseases, and reduce risk of contact transmission.
Virus/bacteria Inactivation By Salt-coated Fibers
-
Step 1: aerosols collect on salt-coated fibers
-
Step 2: aerosols dissolve salt on fibers
-
Step 3: supersaturation, followed by salt crystallization as aerosols evaporate
-
Growing crystals destroy pathogens during recrystallization process.
Salt-coated mask filter
-
Have no concern over the toxicity of materials due to the use of biocompatible and safe salts
-
Have strain-nonspecific protective efficacy (thus, no concern over a mutant generation)
-
May be safely reused
-
Resolve concerns over the shortage of mask/respirators during pandemics
-
Can be manufactured with a minor change in current mask/respirator production processes
