## Abstract

PROJECT SUMMARY
The goal of this project is to develop a solution that allows for rapid, safe, and scalable initial treatment and
transport of patients with highly transmissible infectious diseases. This is a necessary innovation because
resource management and infectious transmission control were two of the greatest challenges healthcare
providers faced when fighting the COVID-19 pandemic. When a patient is suffering from highly transmissible
respiratory diseases and requires breathing assistance, they are placed in negative pressure rooms.
However, given the limited supply of negative pressure rooms available to prevent virus transmission, and
the misperception regarding the safety and effectiveness of negative pressure rooms, a new solution is
needed. To help prevent the spread of highly transmissible infectious diseases, start-up company Inspire Rx
has developed a personal negative pressure device called the AerosolVE™ BioHelmet. The BioHelmet is
capable of preventing the spread of aerosolized pathogens while also enabling the use of non-invasive
oxygen therapies on patients with respiratory diseases such as COVID-19, influenza, tuberculosis, measles,
and chicken pox. The negative pressure AerosolVE™ BioHelmet immediately isolates patients with any
highly transmissible respiratory infectious disease and serves as an instant personal negative pressure
environment that is more effective than a traditional negative pressure room. The BioHelmet is intended to
provide safe transportation via ambulance, airplane, or helicopter, allowing critical EMS and transportation
staff to remain safe, and it can also be used in any area of a hospital (including waiting rooms, hallways,
imaging facilities, and any patient room). In this project the team will refine and further evaluate the
AerosolVE BioHelmet, building on their preliminary data collected during the COVID-19 pandemic. They will
first refine the BioHelmet design and fabricate 5 AerosolVE BioHelmets and pump units for follow-on bench
testing and obtaining end-user feedback (Aim 1). They will conduct performance and bench testing for the
different device components of the BioHelmet to demonstrate that the device performs as expected for its
intended use, including particulate testing (Aim 2). Finally, they will obtain end-user feedback from clinicians,
hospital administrators, and others to inform final design requirements (Aim 3). In a future Phase II grant, they
will conduct performance and bench testing in FDA approved labs to ensure safety and efficacy, as well as
clinical testing to ensure the BioHelmet can be comfortably worn for an extended period (several days). They will
then submit an FDA 510(k) application to enable commercialization. The BioHelmet will provide a novel,
compact, portable, and inexpensive solution that offers a safe negative pressure environment both inside and
outside the hospital, which will ultimately save lives by protecting healthcare workers while treating patients.
