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 whereone 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 treatedis 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.
本发明涉及一种用于封闭式循环呼吸的便携式循环呼吸系统。为了在保证氧气浓度正确的情况下使循环呼吸模式期间的氧气消耗最小化,经由至少三个单独的氧气供应阀51、52、53,采用分阶段加入氧气而将氧气加入到该呼吸通路中。前两个氧气供应阀是经校准的喷嘴,其中一个喷嘴51在正常呼吸期间不断输送预定量的氧气,并且第二个喷嘴52在待治疗者呼吸沉重时以第二预定量加入更多的氧气。第三个阀仅手动打开,并且输送很短的一段氧气在几秒内填充该循环呼吸系统及其呼吸袋。
