一、工作原理（Working Principle）
中文
核心采用 GANSHORN SharpFlow 超声流量传感器，通过超声脉冲在气流中的传输时间差，直接、无接触测量流量与体积，无机械涡轮，免日常校准、零阻力GANSHORN Medizin Electronic GmbH。搭配高精度实时 CO/He 气体分析器，捕捉 CO 洗入 / 洗出曲线与 He 稀释曲线，结合内置温湿度 / 气压传感器完成 BTPS 校正，计算 TLCO（一氧化碳转移因子）、FRC（氦气功能残气）等参数，同时识别死腔与肺泡平台，识别弥散 / 分布异常GANSHORN Medizin Electronic GmbH。智能需求阀（IDV）控制气体消耗，实现单次呼吸弥散（DLCO）+ 实时 Intrabreath 分析，无需憋气，操作更自然。
English
PowerCube Diffusion+ is built on GANSHORN SharpFlow ultrasonic flow sensor technology, which measures flow and volume directly via transit-time differences of ultrasonic pulses in airflow. The sensor is contact-free, turbine-free, calibration-free for daily use, and delivers zero resistance to airflowGANSHORN Medizin Electronic GmbH. It integrates high-precision real-time CO/He gas analyzers to capture CO wash-in/wash-out curves and He dilution curves, combined with onboard temperature/humidity/barometric sensors for BTPS correction. Key indices including TLCO (carbon monoxide transfer factor) and FRC (helium functional residual capacity) are calculated; dead space and alveolar plateau are identified for accurate detection of diffusion/distribution disordersGANSHORN Medizin Electronic GmbH. The Intelligent Demand Valve (IDV) optimizes gas consumption, enabling single-breath DLCO + real-time Intrabreath analysis without breath-holding for natural patient maneuvering.

五、使用方法（Operation Method）
中文
准备
开机自检，通过 LFX 软件录入患者信息（年龄、性别、身高、体重、吸烟史），选择测试模式（弥散 / 肺容积 / 常规通气）
患者取坐位 / 立位，安装一次性 ScoutTube 咬嘴，夹鼻夹，确保口唇密封
环境温度 20–25℃，避免电磁干扰、气流直吹
核心测试
DLCO（单次呼吸弥散）：平静呼吸 2–3 次→深吸气至肺总量→屏气 10 秒→快速呼气至残气位，设备自动采集 CO/He 曲线并计算 TLCO/FRC
FVC/FEV1：平静呼吸 3 次→最大深吸气→最快最用力呼气至完全排空，重复 2–3 次，取变异率 <5% 最佳值
MVV：指令最快最深呼吸 12 秒，自动计算 1 分钟最大通气量
舒张试验：按软件梯度给药，对比用药前后 FEV1/FVC 变化
结束与数据处理
自动生成报告（含流量容量环、CO/He 曲线、质控评级），支持打印 / XML/EMR 导出
丢弃一次性咬嘴，清洁设备外表面，LFX 软件归档数据并生成趋势分析
English
Preparation
Power on self-test; enter patient info (age, gender, height, weight, smoking history) via LFX software and select test mode (diffusion/lung volume/spirometry)
Patient sits/stands upright; attach disposable ScoutTube mouthpiece, apply nose clip for tight lip seal
Test at 20–25℃, avoid electromagnetic interference and direct airflow
Core Tests
DLCO (Single-Breath): 2–3 quiet breaths → full inspiration → breath-hold for 10 seconds → rapid expiration to residual volume; device auto-captures CO/He curves and calculates TLCO/FRC
FVC/FEV1: 3 quiet breaths → max deep inspiration → fastest/forceful expiration to full empty; repeat 2–3 times, accept best value with variability <5%
MVV: Breathe fastest/deepest for 12 seconds; auto-calculate 1-minute max ventilation
Bronchodilator Test: Administer drugs per software gradient; compare pre/post FEV1/FVC changes
Completion & Data Handling
Auto-generate report (flow-volume loop, CO/He curves, QC rating); print/export as XML/EMR
Dispose of mouthpieces; clean device exterior; LFX software archives data and generates trend analysis
