上海医疗器械修理厂在长期从事肺量计生产的基础上,吸取了国内外同类产品的特点,同上海中山医院肺功能研究室协作,试制成功了 FJD—80型肺量计,并于 80年投入市场。该计采用微型轴承来降低机械摩擦力,气道内装有鼓风机,使 Co_2迅速被吸收等新的设计方案,因而提高了肺量计的测定精度 Based on long-term production of spirometers, Shanghai Medical Device Repair Factory absorbed the characteristics of similar products both at home and abroad and cooperated with the Laboratory of Pulmonary Function of Shanghai Zhongshan Hospital to successfully manufacture the FJD-80 spirometer. In 1980, Put on the market. The meter uses a miniature bearing to reduce the mechanical friction, the airway is equipped with a blower to make the Co_2 absorb quickly and other new design solutions, thus improving the spirometry measurement accuracy
