肺功能是检查人体健康状况的重要项目。使用先进的LR-80型流速-容量记录仪所描绘的最大呼气流速-容量曲线,可迅速测定气道的畅通情况,是早期诊断慢性阻塞性肺部病变(肺气肿、气管炎等)的重要参考指标。LR-80型流速-容量记录仪在描绘流速-容量曲线的同时,还可记录时间-肺活量曲线,以获得肺活量和时间肺活量的百分比等参数,是医疗单位必备的肺功能检查设备。该仪器主要由流速传感器、微压差换能器、肺活量计、曲线和计时描绘器组成,并辅以管道、阀门、传动机构和操作面板。其结构示意图如下:
Pulmonary function is an important item to check human health. Using advanced LR-80 flow-volume logger, the maximum expiratory flow-volume curve allows rapid determination of airway flow and early diagnosis of chronic obstructive pulmonary disease (emphysema, bronchitis, etc.) The important reference index. The LR-80 Flow-Capacity Logger, while plotting the flow-capacity curve, also records time-versus-vital capacity curves for parameters such as vital capacity and percentage of time vital capacity. It is an essential lung function test device for medical units. The instrument is mainly composed of flow sensor, micro differential pressure transducer, spirometer, curve and timing plotter composition, supplemented by pipes, valves, transmission and control panel. Its structure diagram is as follows:
