Abstract

用于吸入和分配组分的单腔装置(5)包括注射器壳体(1)以及可由柱塞单元致动的活塞(2)。该装置进一步设置有混合组件(3)，该混合组件(3)的混合杆(10)被引导通过活塞(2)并且操作性地连接于柱塞单元(4、21、24)，柱塞单元(4)包括柱塞杆(13)，该柱塞杆(13)铰接(12)于混合杆(10)并且设置有可与混合杆接合的部件。这样，可在简单而又便宜的单腔装置中产生并分配不同组分的混合物(26)，特别是骨接合剂。

Description

用于吸入和分配组分的单腔装置
技术领域
本发明涉及根据权利要求1的前序部分所述的一种用于吸入和分配组分的单腔装置。从US-A-3 195 778中已知这种装置，在该文献中必须插入由混合杆所驱动的单独的推杆来分配混合物。
背景技术
在医疗技术领域中，经常需要将液态、糊状、和/或粉末形式的两种或更多种组分，例如骨接合剂，混合以用于多种应用。这些组分通常被存储在分离的腔或容器中。特别是对于无菌产品而言，关于卫生的安全性以及分离和应用的简单性是相当重要的。因此，一方面应该避免在户外手动计量、组合、以及混合组分，并且另一方面应该避免在封闭的系统中的进行涉及多个步骤的复杂的处理。
发明内容
在该现有技术的背景下，本发明的目的是以这样一种方式改善和简化一种用于吸入和分配组分的单腔装置，即可将液态、糊状、和/或粉末形式的不同的组分集合在一起并将它们混合，以便随后借助于该装置分配最后得到的混合物。
由根据权利要求1所述的装置来实现该目的。在从属权利要求中描述了本发明的另外的可能性和优点。
附图说明
下文中，将参考示例性实施方式的附图更加详细地解释本发明。
图1示出了根据本发明的处于装配状态中的装置的示例性实施方式，
图2在分解图中示出了图1的装置，
图3在纵向截面中示出了图1的装置，
图4.1至4.4示意性地示出了处于不同工作位置中的图1的装置，
图5在截面图中示出了图1的装置中的混合操作，
图6示出了图1的装置的实施方式的变型。
具体实施方式
参考图1至图5，特别是图2，描述该装置的第一示例性实施方式。装置5包括注射器壳体1、活塞2、混合组件3和柱塞单元4。下文中被称作注射器1的出口的出口或入口6分别设置有封闭件7。出口6的尺寸是例如与Luer-Lok系统相应的标准尺寸。
活塞2设置有密封件8，该密封件8相对于注射器壳体1密封其周边并且相对于混合杆10密封其通道9。混合杆10的出口侧上的端部处设置有盘状混合器11，并且在其另一端部处，经由活节铰12附连有柱塞单元4。
在本实施方式中，在柱塞杆13的一个端部处，柱塞单元4设置有具有卡合凹处14的凸缘，该卡合凹处14的尺寸被确定为以致于夹在混合杆10上。在柱塞杆13的另一端部处，设置有带有指支托15的手柄，当分配混合物时，该指支托15与注射器壳体1上的定位凸缘16协作。为了防止将活塞从注射器壳体中拔出，在壳体的端部处设有活塞止动件17。
在图3的截面图中可见，注射器壳体部分地填充有诸如粉末18之类的组分，或组分混合物，从而使得当移除封闭件7之后，可由柱塞单元4拉回混合组件3并由此拉回活塞2，从而使得能够将液体吸入或注入到注射器壳体中。活塞上的密封件8防止混合物可能存在于注射器壳体的另一侧上。
图4.1至图4.4和图5示出了在组分能够被分配之前的吸入和混合组分的不同工作阶段。图4.1示出了柱塞单元4处于填充位置，也就是拉回位置的活塞2，柱塞杆通过具有卡合凹处14的凸缘接合于混合杆10，并被完全拉回。在图4.2的位置中，为了使混合杆能够在不作用于活塞的情况下移位和旋转，已经将柱塞杆枢转了90°。
该纵向移位以及同时发生的旋转运动在图4.3中示出并且由扭曲的箭头19表示。在图4.2和图4.3中，可进一步看出在该操作之前已经附接了封闭件。在图4.4的视图中，已完成了混合操作，已将柱塞杆枢转回90°并且卡合在混合杆10上，从而使得混合杆10经由具有卡合凹处的凸缘作用于活塞。随后，为了分配物质，通过将压力施加于指支托，将柱塞单元、活塞和混合组件朝出口推动。在图5中，在截面图中再次示出了混合操作并且该操作由扭曲的箭头19所表示。当然，在分配混合物26之前，移除封闭件7。
图6示出了柱塞单元4的实施方式变型，在该实施方式变型中，装置20的具有指支托15的手柄被设置在混合杆10上并且柱塞单元21呈经由铰链22连接于手柄的铰接部的形式。该柱塞单元21的功能与前述示例中的相同，即用于混合操作，柱塞单元21被带至图6的位置，并且为了吸入液体或喷出混合物，将柱塞单元卡合在混合杆10上，本实施方式变型的柱塞杆呈对应于混合杆10的槽形截面的形式。
