技术领域
本实用新型涉及经口腔吸入到肺内的吸入装置，具体地说是一种将有生理活性物质的溶液雾化成气溶胶后经呼吸道吸入肺内的吸入雾化装置。
背景技术
现有用于医疗目的的肺内吸入装置已有很多超声雾化器供临床及家庭使用。而现有的肺内吸入雾化装置雾化的粒子直径过大，大部分雾化粒子被上呼吸道及支气管所截留，不能有效的达到细支气管及肺泡，而且携带也不方便。
实用新型内容
本实用新型的目的在于提供一种吸入雾化装置，在利用该装置时雾化粒子小，雾化均匀，便于携带。
本实用新型的目的是通过以下技术方案来实现的：
本实用新型包括壳体及设在其内的电池、气动开关、雾化器及供液瓶，供液瓶上开有吸气孔道，供液瓶的一端连接雾化器，在雾化器的另一侧依次设有气动开关及电池；壳体上开有进气孔。
其中：所述雾化器为射流加热雾化器，包括供液结构体及加热体，供液结构体为多孔体结构或纤维结构，其一端开有射流孔，另一端设有凸起，加热体容置于供液结构体内，供液瓶中的药液透过供液结构体进入其体内；所述雾化器为浸润加热雾化器，包括供液结构体及加热体，供液结构体为多孔体结构或纤维结构，其一端设有凸起，加热体安装在另一端，供液瓶中的药液透过供液结构体进入其体内；所述供液结构体为多孔体结构或纤维结构；加热体可为微孔陶瓷骨架上绕有欧姆金属电热材料或用导电陶瓷/PTC材料制成的带烧结电极的多孔体。；所述气动开关为金属制成的以压力差为动力的机械开并、霍尔器件、半导体力敏芯片、硅矩阵电桥芯片或电容及电感式传感器；所述供液瓶为多孔体结构或纤维结构，瓶内填充有吸液。
本实用新型的优点与积极效果为：
1.本实用新型雾化均匀、雾化粒子小，平均直径可达1微米左右，是用于肺内吸收的最佳技术参数，可全部被吸入。
2.本实用新型结构简单、携带方便，使用不受场所的限制。
附图说明
图1为本实用新型的结构示意图；
图2为本实用新型射流加热雾化器的结构示意图；
图3为图2的右视图；
图4为本实用新型浸润加热雾化器的结构示意图；
图5为图4的右视图。
具体实施方式
下面结合附图对本实用新型作进一步详述。
如图1所示，本实用新型包括壳体2及设在其内的电池3、气动开关4、雾化器6及供液瓶7，壳体7为长条柱体，前端可配有指示灯1。供液瓶7为多孔体结构或纤维结构，瓶内填充有吸液，可以更换；供液瓶7上开有吸气孔道8，供液瓶7的一端连接雾化器6。在雾化器6的另一侧依次设有气动开关4及电池3，电池3、气动开关4与雾化器串联成回路。气动开关4是用金属制成的以压力差为动力的机械开并，也可用霍尔器件、半导体力敏芯片、硅矩阵电桥芯片或电容及电感式传感器代替。壳体2上开有进气孔5，用于外界空气的吸入。
如图2、图3所示，雾化器6可为射流加热雾化器，包括供液结构体101及加热体102，供液结构体101为多孔体结构或纤维结构，其一端开有射流孔103，另一端设有凸起104，射流孔103是用泡沫陶瓷、微孔陶瓷、发泡金属、不锈钢纤维粘或化学纤维成型开孔制成。加热体102容置于供液结构体101内，供液瓶7中的药液透过供液结构体101进入其体内。加热体102可为微孔陶瓷骨架上绕有欧姆金属电热材料或用导电陶瓷/PTC材料制成的带烧结电极的多孔体。射流加热雾化器是利用吸入气流在射流孔103内进行一次雾化，喷射在加热体102上进行二次雾化。
如图4、图5所示，雾化器6可为浸润加热雾化器，包括供液结构体201及加热体202，供液结构体201为多孔体结构或纤维结构，其一端设有凸起204，加热体202安装在另一端，供液瓶7中的药液透过供液结构体201进入其体内。加热体102可为微孔陶瓷骨架上绕有欧姆金属电热材料或用导电陶瓷/PTC(正温度系数热敏陶瓷)材料制成的带烧结电极的多孔体。浸润加热雾化器是用加热体202直接对供液结构体201加热，使药液雾化。
两种结构的雾化器中，位于一端的凸起104、204与供液瓶7相连接，供液瓶7中的药液逐渐透过供液结构体进到其内。供液结构体是用泡沫陶瓷、微孔陶瓷、多孔金属、不锈钢纤维毡或化学纤维成型开孔制成。加热体是用微孔陶瓷骨架上绕有欧姆金属电热材料制成，也可直接用导电陶瓷或PTC陶瓷材料制成的带烧结电极的多孔体。加热体的表面烧结成高温釉以固定沸石颗粒，沸石颗粒由天然沸石、人造无机微孔陶瓷或氧化铝颗粒制成。
本实用新型的工作原理为：药物经丙二醇溶解后，药液装入可更换的供液瓶7中。将供液瓶7放入壳体10内，与雾化器6接触并对雾化器供液。当使用者吸气时，气动开关4在有压力差情况下完成机械式接触、接通电池3和雾化器6，电池3对雾化器6供电，加热体102、202开始加热。使用者吸气，指示灯1发光，雾化器6把供液瓶7中的液体不断的毛细吸出，使之雾化，并由壳体上的进气孔5吸入的空气冷凝、稀释，被雾化器6雾化。雾化器6雾化后的气雾由供液瓶7上的吸气孔道8吸出。
可用于制作供液瓶及供液结构体的纤维结构是用化学纤维或尼龙纤维制成。
本实用新型的雾化器使供液瓶浸润出的液体雾化，并随着吸入的空气稀释为气溶胶形态而被使用者吸入，可用于香烟替代品及肺内给药的医疗器械。
