间歇超声雾化器的设计研讨

Design for an alternative ultrasonic sprayer

报道了对现行超声雾化器的改进方案，通过一个电子开关控制换能器的间歇振动，并实现间歇动作与人的呼吸同步。这不仅克服了现行雾化器持续起雾造成大量药物浪费的缺陷，而且大大降低了整机功耗和故障率，医疗单位也将因此提高经济效益。

This paper presents a sheme for improvement of sprayer. With a electronic switch which controls the transducer to viberate alternatively,the sprayer can make the spraying and respirative act synchronistically. Not only can this design overcome the deficiency in drug waste caused by spraying continously,but also decreases the power consumption and rate. So medical units will benifit from this economically.
