作为一种重要的非注射给药途径 ,雾化吸入治疗方法具有起效快 ,药物毒、副作用小等特点 ,因此被越来越广泛地采用。基于压电驱动喷墨打印机工作基本原理 ,利用微机械加工技术 ,研制了一种压电驱动微喷雾化器。流量、雾粒的直径和速度是微喷雾化器的重要指标 ,文中采用相关的仪器分别对这些指标进行了测试。由测试结果可知 ,微喷雾化器产生的雾粒的直径和速度分布集中 ,且雾粒直径和速度比较适合于雾化吸入治疗 ,可能成为一种重要的雾化吸入治疗装置
As an important non-injectable route of administration, nebulized inhalation therapy is more and more widely used because of its rapid onset, drug toxicity and small side effects. Based on the basic principle of piezo-driven inkjet printer, a piezoelectric-driven micro-spray atomizer was developed by using micro-machining technology. The flow rate and the diameter and speed of the fog particles are important indicators of the micro-spray nebulizer. The relevant instruments were used to test these indexes respectively. From the test results, it can be seen that the diameter and velocity distribution of the fog particles generated by the micro-atomizer are concentrated and that the diameter and the velocity of the fog particles are more suitable for atomizing inhalation treatment and may become an important atomization inhalation treatment device
