最近国际公司研制了一种小型呼吸机能测定仪(mini-wright Peak Flow meter 简称MWPFM)该装置可供医院使用,也可供患者在家使用。家用时完全可以掌握呼吸障碍情况。其活动部件的惯性很小,基本可忽略不计,加速时基本不产生误差。患者将气呼到无菌塑料咀内,气体顺着园管把活塞顶起,槽被扩大,气体在槽处的损耗由弹簧张力保持平衡。呼 Recently, International developed a mini-wright Peak Flow meter (MWPFM) for use in hospitals and at home. Home can fully grasp the situation of respiratory disorders. The inertia of its moving parts is very small, basically negligible, the basic acceleration does not produce errors. The patient breathes air into the sterile plastic nozzle, the gas pushes the piston down the garden tube, the groove is enlarged, and the loss of gas in the groove is balanced by the spring tension. call
