结构及组成/主要组成成分 产品由主机(包括显示器和外壳),附件(包括呼吸手柄和手柄帽、一氧化氮传感器和一次性吹嘴和充电式电池(电池型号:BJ-G510039AA),USB数据线,电源适配器和电源线组成。其中,一氧化氮传感器有测试100、300、500和1000次四种规格。
适用范围/预期用途 本产品用于测定呼出气中的一氧化氮浓度。该产品可用于4岁及以上的患者。

一、工作原理(Working Principle)
中文
采用电化学传感+ 气流控制 + 零气校准技术:
开机自动检测环境温湿度、气压,验证传感器与呼吸手柄连接。
患者通过一次性滤嘴深吸气(滤除环境NO),再匀速呼气 10 秒(6 秒模式适配 7–10 岁儿童),仪器仅采集呼气末 3 秒肺泡气。
呼出气体进入电化学传感器,NO 与电极发生氧化还原反应产生电流,电流强度与 NO 浓度(ppb)呈线性关系。
实时扣除环境零气值,自动计算并显示FeNO 结果,全程约 1 分钟。
English
Adopts electrochemical sensing + precise airflow control + zero gas calibration:
On power‑on, auto‑checks ambient temp/humidity/pressure, verifies sensor & breathing handle connection.
Patient inhales deeply via disposable filter (removes ambient NO), exhales steadily for 10s (6s mode for 7–10yo); only last 3s of alveolar air is sampled.
Exhaled gas enters electrochemical sensor; NO undergoes redox reaction to generate current, linearly proportional to NO concentration (ppb).
Real‑time ambient zero subtraction; FeNO result calculated & displayed in ~1 min.
