Abstract

A small reservoir for the Wright jet nebulizer was constructed and tested with regard to output and particle size characteristics. The Wright nebulizer has found widespread use for bronchial challenge testing. The new small reservoir delivers an aerosol with a size distribution comparable to that delivered from the standard reservoir. Comparable results were obtained when bronchial challenge with either the small or the standard reservoir was performed in 11 patients. The cost for bronchoconstrictor can be reduced by 50-80% by reducing the volume necessary for challenge. It is documented that calibration of the actual set-up is necessary to control the output from a nebulizer, since the output is, not linearly correlated to the flow.

摘要

制作了一个用于赖特喷射雾化器的小型储液器，并对其输出和粒径特性进行了测试。赖特雾化器已广泛用于支气管激发试验。新的小型储液器产生的气溶胶粒径分布与标准储液器产生的相当。在11名患者中使用小型储液器或标准储液器进行支气管激发试验时，得到了类似的结果。通过减少激发所需的体积，支气管收缩剂的成本可降低50 - 80%。有文献记载，由于雾化器的输出与流量并非线性相关，因此需要对实际装置进行校准以控制其输出。
