The first commercially produced version of the Navy’s PRE-Vent is being built for a final round of U.S. Food and Drug Administration testing that aims to prove the design can be manufactured from biocompatible materials and pass stringent agency guidelines for emergency use authorization. The build should be completed this January and then sent for evaluation to the FDA.
The ventilators can be assembled from materials commonly found at hardware stores with a cost of $300 to $600, significantly less than commercially available ventilators. The ventilators can be built on the fly to address patients’ breathing assistance needs in field hospital settings.
Transporting COVID-19 patients by air led to another innovation to protect patients, providers and aircrew during flight.
The Air Force’s Negatively Pressurized Conex (NPC) allows for the safe air transport of patients exposed to COVID-19 without risking the aircrew’s health by surrounding patients within a negatively pressurized containment system. This system allows for the transport of up to 24 infected personnel seated or up to eight stretchers. Thus far during this global pandemic, the Air Force has successfully completed some 65 COVID-19 aeromedical evacuation missions.
The need to protect health care workers from COVID-19 led to the development of the COVID-19 Airway Management Isolation Chamber, or CAMIC. CAMIC is a an adjunct personal protective equipment (PPE) barrier device constructed by placing a large clear plastic bag on a PVC piping box frame over the head, neck and shoulders of patients. When used with other PPE, CAMIC protects health care personnel by providing a physical barrier to aerosolized droplets from patients with COVID-19 by capturing and removing viral particles emitted by the patient. CAMIC was conceived, designed, built and tested by the Army’s Telemedicine and Advanced Technology Research Center.
In a similar vein, researchers from the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory and the University of Pittsburgh Medical Center created an individual biocontainment unit that uses negative pressure to suction the air from around a patient and filter out viral particles.
While 2020 proved to be an active year for operational medical innovations because of the global pandemic, the MHS continuously develops creative protocols, systems or devices that can be used in austere environments where energy sources are limited and where the military is deployed.
