| 摘 要： | 目的：为了提高体内的氧含量,克服浮标式氧气吸入器吸氧量少及呼气时氧气有浪费的不足,设计一种高流量氧气吸入器。方法：该氧气吸入器由气源接头、缓冲气罐、流量计、呼吸器及闭式吸氧面罩5个部分构成,分为墙插式（A型）和瓶插式（B型）2种型号,采用闭式面罩吸氧。结果：该氧气吸入器的吸氧量是浮标式氧气吸入器的3倍左右,呼吸时没有氧气流出,不会造成氧气浪费,其动脉血氧分压较鼻导管吸氧提高了3．1倍。结论：该高流量氧气吸入器操作简单,使用便捷、安全,可迅速、高效改善患者缺氧状况。

| Abstract: | Objective To design a high-flow oxygen inhalator to solve the problems of the buoy-type one including insufficient oxygen intake and waste of oxygen while exhaling, so as to increase the oxygen content in human body.Methods The inhalator was composed of gas source connector, buffer gas tank, flowmeter, respirator and closed oxygen mask, which was divided into two types of wall-plug and cylinder-plug. The closed mask was used for oxygen inhalation.Results The oxygen intake by the inhalator was 3 times of that by the buoy-type one, with no oxygen spilling over. The arterial partial pressure of oxygen by the inhalator was 3.1 times of that by nasal catheter. Conclusion The high-flow oxygen inhalator is convenient and safe to improve the anoxia of the patient. [Chinese Medical Equipment Journal, 2014,35（7） ：45-46,136] |
