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.
An empty device designed as a portable, supplemental, refillable container intended as a storage for liquid oxygen (LOX) and its conversion into gaseous form for delivery of medical oxygen (O2) at various pulsed or fixed flow settings to a patient who typically has difficulty extracting O2 from the atmosphere. It typically consists of a cryogenic canister containing the LOX, a mechanism (e.g., a warming coil) where the LOX is converted into gas, a gas delivery control device (e.g., demand valve or fixed flow mechanism) that regulates the flow of O2 to the patient, a fill port and an outlet connection for connection of a nasal cannula or face mask.
