Hyperoxic therapy systems, methods and apparatus

A hyperoxic gas delivery system comprising:

• (a) a breathing hood assembly comprising:
• a hood assembly including a hood ring and a sealable tent portion, wherein the hood ring includes a first portion and a second portion adapted to releasably attach to an O-ring finish of the sealable tent portion;
• and
• a neckseal ring assembly including an elastic neck dam and a neckseal ring, wherein the neckseal ring includes a first portion and a second portion adapted to releasably attach to an O-ring finish of the elastic neck dam,
• wherein the hood ring is adapted to sealably engage the neckseal ring,
• wherein the neckseal ring includes a plurality of service ports that are covered by a cowling operative to impose directionality to gases flowing through the breathing hood assembly and protect the plurality of service ports, the cowling having a plurality of compartments divided by a centrally located internal bulkhead that separates incoming gas from exiting gas, such that gas flows in one direction only through the breathing hood assembly;
• and
• a securing system adapted to couple to the neckseal ring assembly, the securing system being operative to hold the hood assembly and the neckseal ring in place on a patient during operation of the breathing hood assembly, the securing system including one or more elastic suspender, each one or more elastic suspender being attached at one end to a ball that fits into a slot on the neckseal ring and at the other end to a suspender fastener for securing to the patient;
• and
• (b) control unit coupled to the breathing hood assembly via an umbilical,
• wherein the control unit is adapted to deliver hyperoxic gas to the breathing hood assembly via the umbilical and to maintain pressure in the breathing hood assembly at approximately one atmosphere or in the range of approximately 6 cm H2O to approximately 10 cm H2O pressure.
