Description
本发明涉及医疗设备领域，尤其涉及一种储库型干粉吸入器。
干粉吸入剂是指将药物粉末装填于一药物储库中，患者通过吸入器吸气，将粉末分散成雾状后吸入气管或肺部发挥疗效。当前的干粉吸入剂是呼吸触动型，药物分散和粉雾的产生源动力来自患者的吸气。因为药物以粉末状填装，因而载药量可以很高；作为固态，有利药物的稳定性。特别是呼吸触动给药，病人的配合度高，因而近10年来，干粉吸入剂得到了突飞猛进的发展。不仅短期内干粉吸入剂作为治疗气管或肺部的局部用药是最具吸引力的，而且从长期来看，其在全身性转运生物分子、抗生素及基因工程药物方面具有更重要的潜在优势。
药物粉末通过干粉吸入装置传递至肺部前需要满足一定的条件。首先药物粉末在呼吸道这种特殊的气流环境中表现出来的粒径分布应在一定范围之内。一般认为3～7μm粒径可在支气管较好地沉积，而1～3μm则可沉积到肺深部区域。大于7μm的微粒易被上呼吸道截留，过小的微粒在进入末端支气管后又易随着患者的呼吸而呼出体外。细微的药物粉末由于表面张力大，易团聚，流动性差，很难进行填充和分剂量。因此干粉处方中通常加入较大粒径的乳糖(80～300μm)作为载体。药物粉末分散附着在载体表面，流动性得到很大提高，剂量准确性提高，因而得以广泛应用。

下面结合附图对本发明作进一步详细描述。
一、本发明的基本构造
如图1-8所示，本发明的一种实施例为一种储库型干粉吸入器，包括底座1、主体2、单向控制装置3、计数部件4、气道部件5及吸嘴部件6，所述底座1位于主体2下部，计数部件4置于底座1和主体2内，吸嘴部件6位于主体2上部；计数部件4包括齿轮部件41及单向控制装置42；齿轮部件41包括安装在底座1内中部的主齿轮411，主齿轮411转动时带动与其啮合的从动齿轮412转动，从动齿轮412的另一端小齿轮413捏合，小齿轮413同时与安装在底座内周边的数字齿条414啮合，主齿轮定向旋转一次，带动数字齿条单向运动一次。
单向控制装置3包括单向轴31和单向轴32，单向轴31安装在主齿轮上，单向控制装置3确保只将主体2一个方向的旋转传动到齿轮部件41上；所述主体2上部安装上盖21，中部安装药盖板22，上盖21分为两部分分别为第一上盖211和第二上盖212，所述第一上盖211为储药室上盖，第二上盖212为主体其他部件上盖。所述药盖板22通过支架23固定在主体2内,所述支架23安置在单向轴32上；所述主体2内的药盖板22与顶盖24间纵向分隔为储药室25、干燥剂储存室26和吸药通道27；所述支架23和药盖板22之间装配弹簧28，将药盖板22压紧在储药室或吸药通道下沿。所述药盖板22上表面设有给药仓221，主体2旋转过程中所述给药仓221在储药室25和吸药通道27之间切换。本实施例中给药仓221为梯形凹陷结构而其他情况下也可以为为圆形凹陷结构或其他形状结构，但给药仓221的容积一般
为一次给药所需的剂量。药盖板22上表面还设有立柱222，在主体2旋转时，该立柱222位于储药室25内。所述支架23与药盖板22之间设置有弹簧装置231，弹簧装置231将将药盖板压紧在吸药通道下沿。所述干燥剂储存室26内放置干燥剂，保持装置内部干燥。吸嘴部件6位于主体上方，气道部件7为双圆弧形结构，其位于吸嘴部件内，一端与主体上的吸药通道27相连。主体2上加设主体盖7，主体盖7对吸嘴部件产生保护。所述底座1上可以设置显示窗11，计数部件4转动一次后的结果在显示窗11中通过数字显示。
二、本发明的工作原理：
干粉吸入器按剂量多少可分为单剂量和多剂量两种，其中多剂量型又可分为厂家预分剂量型(泡罩型)和储库型。本发明所涉及的吸入器为储库型，是由计数器，储库，料槽，气道，粉末分散部件以及干燥剂存放室等零件组成。
本发明的工作原理及流程包括：
1，使用者操作本发明实施例所示的储库型干粉吸入器时，可以左手握住底座部分，右手握住主体部分并进行逆时针旋转，直至到达限位角度无法旋转为止。本实施例中实现限位角度是通过在主体下部设两个方柱，主体旋转时方柱会和固定在底座上的支架块相碰，靠支架限制主体继续转动。以达到限位效果，正向和反向旋转的限位方式相同；当主体作逆时针旋转时会带动单向控制装置中的单向轴转动，而单向轴则带动主动齿轮旋转，主动齿轮旋转会带动从动齿轮及小齿轮旋转，主体旋转一次，带动数字齿条运动一个单元，并可以通过数字齿条关联的计数显示窗显示数字。
同时，由于主体旋转，药盖板上的给药仓从储药室下方切换到吸药通道下方，干粉吸入器进入吸药状态。使用者可以在此时用嘴含住吸嘴，用力吸气，通道内会产生负压，药粉会随气流流动，到达患者的肺部，达到给药治疗的效果。
2，吸药后，主体作顺时针旋转，到不能转动为止，此为复位。在主体顺时针旋转时，由于单向控制装置的作用，单向轴不将转动传动到计数装置的主齿轮上，因此计数装置关联的计数显示窗上显示的数字不发生变化，在整个一个循环过程中，计数装置会走动一次，数字会变动一个单元，从而准确统计患者吸药次数的目的。无论使用者是否吸入药物，或者是否完全将药物吸入，主体复位后，药盖板上的给药仓从吸药通道下方切换回储药室下方，保持盛载一个单位剂量的药量，并可防止在吸药通道中泄漏或潮解。本实施例中的吸药量每次为恒定，有效统计吸药次数为60次；同时本实施例的药盖板上加装一立柱机构，在主体转动的循环过程中，该立柱机构在储药室内运动，可以有效的搅动储药室内的药粉，使得药物加装
更加均匀，加强要药粉分散度，来回搅动药粉，以达到粉末流动，保证粉末能进入到药板上的药仓内。同时为了保持药粉的干燥性，本实施例设置了干燥剂储存室，并在其中添加干燥剂，保持干粉吸入器内部的干燥性。
6，计数器：本实施例中的数字齿条上会印有数字，每次吸药后能读到余下还可以吸药的次数，最终所见的数字就从数字齿条上反馈给患者。
7，闲置不使用时，本实施例中干粉吸入器可以盖上主体盖，以保护吸嘴部件的清洁。
8，本实施例利用空气动力学原理设计了一个双园弧形气道，药物及载体粉末在通过该气道时可产生足够大的湍流，将聚集的团块打散，并使药物与载体充分分离，以产生最大比例的最佳粒径微粒。很好的解决了药物粉末分散和气流阻力的矛盾，得到最佳效果。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化涵括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。此外，显然“包括”一词不排除其他单元或步骤，单数不排除复数。装置权利要求中陈述的多个单元或装置也可以由一个单元或装置通过软件或者硬件来实现。第一，第二等词语用来表示名称，而并不表示任何特定的顺序。
