Groundbreaking Personal Protective Equipment

With the emergence and rapid spread of Covid-19 Coronavirus, we at Medi-Immune are working to bring our Personal Protective Equipment Device, ProtectivAir®, to the attention of key National and International decision makers, who can complete the development in the shortest possible timescales, so that Health Workers, First Responders and other critical groups, can be better protected during this pandemic.

What is ProtectivAir®

ProtectivAir® is a wearable, filter-free, breathing device that biologically sterilizes inhaled air, providing immediate protection against any airborne pathogen, even mutations.

If a pathogen has not yet been identified, or is a mutation of a known pathogen, ProtectivAir® will still protect. This allows time for the identification and subsequent production of a vaccine.

This technology has been confirmed in tests at Public Health England,
Porton Down. To view report click here

ProtectivAir® Patented Technology

Within the filter free irradiation chamber, energetic UVc photons pass through the infecting micro-organisms, damaging their nucleic acid (RNA or DNA) which disables their ability to replicate and infect the body.

The use of UVc in disinfection/decontamination is widely accepted and all published data confirms that UVc is an extremely effective germicidal agent.

Training: Minimal user training required

Wearer Suitability Study

One of the targeted end users of The Medi-Immune ProtectivAir® are healthcare
professionals who work in an environment potentially exposed to airborne pathogens
e.g. first responders, emergency services, military, and public servants. It is also
envisaged that the general public will benefit from its use, particularly those with
compromised immune systems.

The conducted usability study was structured around simulated tasks, based on
working scenario for 4 volunteers, all of whom are research nurses with varying levels
of experience.

All the participants were able to carry out the tasks proficiently whilst wearing the
ProtectivAir® device.

Overall there was a positive response from the participants to the PPE device tested. It
was described as “user-friendly” and “more comfortable than other current

The participants appreciated the purpose of the ProtectivAir® suggesting that if staff
were aware of the benefits, it would likely be welcomed, especially as it is more
comfortable than other masks.

The participants were able to complete all the tasks required of them, whilst wearing
the PPE device. Therefore, there is a completion success rate of 100% for the
representative end users.
