Naval Surface Warfare Center (NSWC) Corona Division has designed a portable medical oxygen manifold for Naval Hospital Camp Pendleton to fight against the coronavirus (Covid-19) pandemic.

The low-cost, mass-producible device has been designed in a few hours at the request of Combat Logistics Regiment 15 (CLR-15) Marines.

It features multiple flow rate valves and eight outputs and allows the simultaneous provision of oxygen to eight patients from a single oxygen cylinder.

In its current design, 20 portable medical oxygen manifolds can be produced for about $375. The production and assembly of the equipment requires little or no lag time.

NSWC Corona’s expeditionary systems engineering division chief scientist Dr Ryan Olsen said: “It’s important to have a selection of viable solutions available at all times. This is a fast, viable, and inexpensive solution.

“In a crisis, you don’t have a month to find a solution. There’s not a lot of warning and not a lot of time to respond, but it still requires a good engineering solution. Those good solutions are something we strive for in all the work we do.”

There has been a constant storage of medical respiratory devices globally for treatment as the pandemic continues.

To meet the demands, the navy and Marine Corps’ focus on readiness and continue advanced planning and preparation for the unexpected.

A prototype for the oxygen manifold was designed following an analysis of additive, subtractive and reverse engineering options by the NSWC Corona Expeditionary Solution Cell (ESC).

The manifolds were designed by combining computer-aided design software with engineering technology and readily available parts. The team also reverse engineered an existing manifold hardware.

The portable device maximises the Naval Hospital’s medical resources within a brief notice and augments the supply stockpile.

NSWC Corona recently extended a similar support to California Rehabilitation Center, Norco with 3-D printed face shields to avoid the spread of the virus.
