Description
本发明涉及医疗器械技术领域,尤其涉及一种雾化装置及快速雾化方法。
随着工业化和城市化的不断发展与深入,城市的空气质量越来越差,人们的呼吸系统疾病越来越普遍和频繁,但相反的,人们对生活品质的要求越来越高,因此,人们希望拥有快速有效的呼吸系统疾病治疗方法和设备。
医疗器械中包括一种雾化器,雾化器主要用于治疗各种上下呼吸系统疾病,如感冒、发热、咳嗽、哮喘、咽喉肿痛、咽炎、鼻炎、支气管炎、尘肺等气管、支气管、肺泡、胸腔内所发生的疾病。雾化吸入治疗是呼吸系统疾病治疗方法中一种重要和有效的治疗方法,采用雾化器将药液雾化成微小颗粒,药物通过呼吸吸入的方式进入呼吸道和肺部沉积,从而达到无痛、迅速有效治疗的目的。
雾化片是雾化器的重要元件之一,常用的雾化片为网式雾化片(也称微孔雾化片),网式雾化片主要由压电陶瓷片和贴覆在陶瓷片上的震动片组成,压电陶瓷片和震动片上分别引出一根导线,使用过程中,对雾化片施加电压,当激励电信号通过导线传递至压电陶瓷片后引起压电陶瓷片振动,进一步带动震动片一起振动。震动片上分布有大小均匀的若干微孔,在振动的激励下不断挤压液面,达到一定频率和振幅后,与震动片接触的部分液体通过微孔被挤出,形成微小的液滴,产生雾化。
雾化给药时,雾化出来液滴中,只有1-5微米的液滴才能入肺,到达病灶,实现治疗效果。雾化出来的1-5微米液滴比例越多,治疗效果越好。目前市售雾化装置有空气压缩式,氧气压缩,超声式。但这些雾化装置都有以下缺点:雾化速率(单位时间内喷出的雾的量)慢大约是2-3mg/s,导致给药时间长,连续雾化3-5分钟;吸入给药的操作麻烦,顺应性差;给药过程中,不论使用者是否吸入雾滴,装置都在喷雾,使使用者过多的吸入药物,药物浪费严重;由于雾化原理的限制,这些装置增大雾化速率后,会使雾滴中1-5微米的液滴比例大大降低,入肺药物比例小,药物浪费增大。所以综合考虑采用了低速长寿命的装置设计方案。
网式雾化装置是一种基于超声雾化原理改进的雾化装置,但市售产品的设计理念仍沿用以往装置的思路,即低雾化速率,长使用寿命。所以其雾化速率也是2-3mg/s,使用寿命3000-5000小时。现有的网式雾化装置的重要元器件——雾化片——工作电压远低于其额定电压,以保证其使用的长寿命,因为本领域技术人员认为,若雾化片长期在超负荷下工作,必然会使雾化片损毁,因此现有的雾化装置不会超负荷工作,都存在雾化速率小、喷雾时间长、治疗效果差的缺点。例如额定电压(Vpp)为90伏的雾化片,其实际工作电压只有50-70伏,而且工作电压低于额定电压越多越好。这样预留安全窗的设计方法在许多产品设计中也的确是一种公知常识。另外,现有的网式雾化装置持续工作时间长,如果雾化片连续长时间(几 分钟)高电压大于70伏工作,雾化片上的陶瓷会发热,难以保证雾化片胶水的粘结性能,也难以保证雾化陶瓷性能的稳定。
基于上述情况,我们有必要设计一种能够克服上述技术偏见、解决上述问题的雾化装置和方法。
发明内容
本发明的目的在于:提供一种雾化装置,能有效提高药物的雾化速率。
本发明的另一个目的在于:提供一种快速雾化方法,能有效提高药物的雾化速率。
为达此目的,本发明采用以下技术方案:
一方面,提供一种雾化装置,包括:
雾化片,用于对药物进行雾化处理,具有额定电压;
电压控制元件,与雾化片电连接,用于给雾化片提供工作电压,雾化片的工作电压不小于70V,且工作电压为雾化片的额定电压的60%~150%。
具体地,当雾化片的工作电压不小于70V且为雾化片额定电压的60%~150%时,雾化片的压电陶瓷片接收到的激励电信号较大,雾化片振动增强,能使雾化速率显著提升,结合喷雾和患者的吸气同步,可以使给药时间从几分钟缩短至几秒钟,可以极大的方便使用。而且每天几秒钟的高电压工作并不会使雾化片发热,也不会使寿命缩短太多。当工作电压超过额定电压太多时,会出现雾化片喷出液滴和雾化片发烫现象,1-5微米雾滴的比例降低,雾化效果差,工作电压不超过额定电压的150%,可避免上述情况的出现,且能保证高雾化速率。目前,市场上使用的雾化器由于要预留安全窗以保证其使用的长寿命,工作电压均小于70V,雾化速率低。

具体地,雾化片每次喷雾时工作时间与雾化装置的喷雾次数的乘积等于雾化片的累计工作时间。雾化片的累计工作时间为15~480秒,雾化片的累计工作时间短,在完成喷雾前,雾化片不会损坏。
