摘要： The present disclosure is directed to systems and methods of providing a mixed-gas inhalant to a patient via a gas recirculation loop. The gas recirculation loop receives a first mixed-gas exhalant having a first carbon dioxide concentration from the patient, one or more carbon dioxide removal devices discharge a second mixed-gas exhalant having a second carbon dioxide concentration that is less than the first carbon dioxide concentration. The second mixed-gas exhalant is combined with a mixed-gas supply to provide a mixed-gas inhalant. The mied-gas supply includes a first gas and a second gas. The mixed-gas supply is pressure and flow controlled to produce a mixed-gas inhalant having a defined composition delivered to the patient at a defined volumetric flow rate. The first gas may include a gas containing oxygen and the second gas may include a gas mixture containing a noble or inert gas and oxygen.

摘要： The invention is related to a portable rebreathing system for closed rebreathing. In order to minimize consumption of oxygen during rebreathing mode while safeguarding correct oxygen concentration, oxygen is added into the breathing passage using staged addition of oxygen via at least three individual oxygen supply valves 51, 52, 53. The two first oxygen supply valves are calibrated nozzles where one nozzle 51 is constantly delivering a predetermined amount of oxygen during normal breathing and the second nozzle 52 adds more oxygen at a second predetermined amount when the person to be treated is breathing heavily. The third valve is only opened manually and delivers a short burst of oxygen that fills the rebreathing system and its counter lung within seconds.

摘要： A mouthpiece for a rebreather has a tubular housing having opposed inhale and exhale ends, a mouth port, and a discharge port. Supported for movement within a bore of the housing is a valve assembly which is magnetically biased toward a valve-closed position preventing air in an air space of the bore from moving to the exhale end and the discharge port. As a diver exhales into the mouth port, the increase in air pressure of the air space causes the valve assembly to assume a valve-open position, exposing a transverse channel extending between the air space and the discharge port, and a recirculation air channel extending between the air space and the exhale end. A portion of the exhaled air is exhausted to the ambient environment through the discharge port, while the remainder exits the mouthpiece at the exhale end for recirculation through the rebreather.

摘要： A portable semi-closed breathing apparatus for divers, having a circuit comprising a breathing bellows (1) connected to a pressure gas source (2) for the supply of breathing gas, a demand-controlled breathing valve (20), an actuator (4) for expansion and contraction of the breathing bellows (1) in step with the diver's breathing pattern, a means (5) for compensation of consumed oxygen, and a means (6) for removal of CO 2 from the breathing gas. The actuator (4) is a cylinder/piston unit (9, 10) having a first chamber (11) connected to a source (13) for compensation gas, and a second chamber (12) connected to a valve means (5). During the diver's exhalation phase the valve means (5) is arranged to supply compensation gas to said second chamber (12) under control of the breathing valve (20), so that the breathing bellows (1) expands and absorbs exhaled gas from the diver. During the inhalation phase the actuator (4) contracts the bellows (1) and the valve means (5) delivers compensation gas to the circuit in accurate correspondence with the gas quantity inhaled by the diver, in that the valve means is arranged to keep the pressure in the second chamber (12) at a preset level.

摘要： A closed circuit rebreather system with a modular, detachably affixable breathing bag assembly (10). An interchangeable base unit (12) is provided, preferably in backpack form, containing gas supply bottles (TN), regulation equipment (VN), and interconnecting hoses. A personalized closed circuit modular breathing bag assembly (10) is provided which can be customized for each diver and or for a particular mission, by changing tidal volume and/or gas scrubber (GN) charge size in the breathing bag. The modular breathing bag assembly (10), regardless of customizing, is reliably interchangeable with any one of a plurality of base units (12), via a commonly sized and configured base to breathing bag fastener system. Attachment to the base units with accompanying gas supply and regulation equipment is facilitated by quick connect gas connections, and modular electrical connections. By use of personal modular, breathing bag assemblies, divers avoid the necessity to re-use equipment, thus avoiding biological cross-contamination between subsequent users.

摘要： The present invention is a method and apparatus for a self-contained underwater breathing apparatus (100) in which a breathing gas is supplied to a flow loop (104) from two separate gas sources (110, 112) each having a different oxygen fraction, and each controlled by separate mass flow controllers (120, 122) having variable flow rates. The mass controller flow rates are adaptively adjustable to deliver gas at variable flow rates which depend solely on a function of depth.
