Abstract:
1. A breathing gas delivery system, comprising: a first valve and a second valve, each of the valves having a first port, a second port, and an oscillating member, the first port of each valve adapted to connect to a tube communicating pressurized breathing gas from a source of pressurized breathing gas, an inlet passage defined from the first port to the second port when the oscillating member is in a first position, the inlet passage being closed when the oscillating member is in a second position, each of the second ports being generally upwardly-opening, each of the first ports being generally horizontally-opening, a nasal cannula tip disposed on each second port, the nasal cannula tips being configured to fit into a patient's nostril, the first and second valves sized and configured to fit between a patient's mouth and nose; the first valve having a first connector, and the second valve having a second connector, the first and second connectors adapted to adjustably engage one another so as to attach the first and second valves together so that a space is defined between the first and second valve second ports and so that the first and second valve first ports open in opposite directions; wherein the first and second connectors are adjustable so that the space between the second ports can be selectively adjusted, wherein each valve comprises an elongate chamber having an inlet passage seat at one end and an exhale passage seat at the other end, the oscillating member comprising a ball within the elongate chamber, wherein when the oscillating member is in the first position the ball engages the exhale passage seat, and wherein when the oscillating member is in the second position the ball engages the inlet passage seat.
