A new rhinoresistometer consisting of a pressure nozzle, a flow nozzle, a two-U-tube manometer and a X-Y chart recorder is introduced in this paper. Such an apparatus is simple in construction and easy to use. The expiratory transnasal pressure difference is measured by a U-tube manometer while the nasal airflow is measured by flowmeter. With this apparatus, the subject's nasal airway resistance can be evaluated accurately and the nasal airway resistance curves drawn automatically. The mechanical principle of the apparatus is described and the nasal airway resistances of 200 normal subjects are reported in this article.
本文介绍了一种新型鼻阻力计，它由一个压力喷嘴、一个流量喷嘴、一个双U型管压力计和一台X-Y记录仪组成。这种仪器结构简单，使用方便。呼气时的经鼻压差由U型管压力计测量，而鼻气流则由流量计测量。利用该仪器，可以准确评估受试者的鼻气道阻力，并自动绘制鼻气道阻力曲线。本文描述了该仪器的机械原理，并报告了200名正常受试者的鼻气道阻力情况。
