Backpack Medical Oxygen System, BMOS 50C-0089-4

GUDID 10815363020056

The Backpack Medical Oxygen System (BMOS) is a low pressure, portable 2.0 liter liquid oxygen storage and gaseous delivery system, capable of supplying up to 1720 gaseous liters of oxygen at a maximum flow rate of 15 liters per minute at 50 psig. A built-in flow control valve delivers oxygen to a single patient at flow rates from 0.5 to 15 liters per minute. A secondary accessory port can supply 50 psi of oxygen to other medical devices or to an oxygen regulator for a second patient. The BMOS has been successfully tested to work in tandem with commonly used ventilators. Weighing just 19 pounds when full, the BMOS can be carried or worn by parachutists and ground support personnel. The BMOS requires no external power and uses just six AA-batteries for the quantity indicator. The system has been tested to MIL-STD-810.
