具体实施方式
本发明的一些实施例涉及一种用于药物输送装置的止动部驱动器，并且更特别地但不是专门地涉及一种药物盒的伸缩式止动部驱动器。
概述
本发明的一些实施例的方面涉及一种用于药物输送装置的止动部传动组件的防旋转引导部。可选地，驱动器组件的远端轴通过引导部被旋转地保持静止，同时通过旋转近端元件的相对旋转被向远端驱动到贮存器中。由于远端元件向远端前进到贮存器中，因此轴可以相对于引导部向远端滑动。另外或可选地，引导部和轴可以一起向远端滑动到贮存器中。在一些实施例中，近端元件和远端轴当彼此之间旋转时可以伸缩。近端元件可以相对于贮存器轴向保持固定，从而近端和远端元件的伸缩使得远端轴进入贮存器中。
一些实施例可以包括线性和/或旋转稳定器。例如，旋转稳定器可以由药物输送装置的壳体和/或马达架支撑，从而伸缩组件上的扭矩与防旋转引导部和/或马达和/或输送装置的壳体保持平衡。可选地，扭矩将不被施加于与药物接触的药物贮存器和/或止动部和/或任何部分。
在一些实施例中，止动部和驱动器组件之间的线性力与贮存器保持平衡。可选地，推动组件和止动部之间的线性应力与药物输送装置上和/或贮存器和药物输送装置之间的微不足道的或者没有的外部线性应力平衡。
在一些实施例中，驱动器组件可以附接到药物贮存器以形成盒。整个盒作为一个单元被可选地插入药物输送装置中。在一些实施例中，盒可以量出(meter out)药物，同时在药物输送装置上产生微不足道的或者没有的外部轴向力。例如，盒组件可以包括将TSA连接到药物贮存器的线性稳定器。例如，线性稳定器可以连接到接近贮存器的近端开口和/或在贮存器的近端凸缘上的贮存器。可选地，止动部和TSA之间的线性力可以通过线性稳定器和贮存器之间的力平衡。可选地，整个盒组件插入药物输送装置中的近端开口中。可选地，当盒插入药物输送装置的近端开口中时，套管穿透在贮存器和药物输送装置之间创建流体路径的隔板。例如，隔板可以位于盒的远端上和/或接近盒的远端。可选地或者另外的实例，隔板可以位于药物输送装置的远端部上和/或接近药物输送装置的远端部。
在一些实施例中，盒推动组件可以附接到贮存器的近端开口，而不用考虑止动部在贮存器中的精确纵向位置。可选地，在将止动部推动组件连接到贮存器之后，TSA可以延伸直到推动组件接触止动部。例如，TSA可以在将盒组件插入药物装置之前延伸。可选地或者另外，TSA可以在将盒组件插入药物输送装置之后延伸。
在一些实施例中，TSA的行程长度可以大于TSA的最小长度。例如，TSA可以具有三个伸缩轴和/或三个伸缩引导部。例如，伸缩轴可以包括延伸杆。可选地或者另外，TSA可以具有四个伸缩轴和/或四个伸缩引导部。可选地或者另外，TSA可以具有五个伸缩轴和/或五个伸缩引导部。例如，TSA可以具有长度范围在0.8和1.6cm之间的缩回构造和/或长度范围在2.0至4.0cm之间的延伸构造。可选地，TSA的延伸长度可以介于缩回长度的2.0至3.0倍之间和/或介于缩回长度的3.0至5.0倍之间。
在详细说明发明的至少一个实施例之前，可以理解，发明不是将它的应用必需限制到下文的说明中所阐述的和/或附图和/或实例中图解的部件和/或方法的详细构造和布置。发明能够用多种方式实践或者进行其它实施例。
盒组件
现在参照附图，图1A是根据本发明的实施例的止动部传动组件150的方框图。传动组件150可选地包括线性稳定器106，该线性稳定器106支撑驱动器组件150和/或平衡驱动器组件150和止动部(例如图1B的止动部140)之间的线性力。驱动器组件150可选地包括防旋转引导部，例如引导部104。防旋转引导部104可选地支撑驱动器组件和/或平衡驱动器组件和马达(例如图1B的马达108)之间的扭矩。
在一些实施例中，止动部驱动器组件150可以包括伸缩组件(例如TSA 152)。可选地，TSA 152包括近端轴和/或远端轴，近端轴例如为螺纹传动轴110和/或螺纹中间轴112，远端轴例如为螺纹推动轴114。轴110、112和/或114可以被联接成使得传动轴110相对于推动轴114的旋转使得TSA 152伸长和/或缩短。可选地，通过线性稳定器106限制传动轴110的轴向移动，从而传动轴110相对于推动轴114的旋转使得推动轴114相对于线性稳定器106线性移动。可选地，联接部(coupling)将推动轴114链接到防旋转引导部104。例如，推动轴114的旋转可以受防旋转引导部104限制，从而传动轴110相对于防旋转引导部104的旋转使得TSA 152伸长和/或缩短。可选地或者另外，传动轴110和/或推动轴114可以被螺母和/或螺纹圆盘和/或环替代。
图1B是根据本发明的实施例的插入药物输送装置122中的盒153的方框图。可选地，盒153包括传动组件150、药物贮存器120和/或止动部140。可选地，药物输送装置122包括马达108。可选地或者另外，马达108可以包括直流电动机、化学发动机、无刷马达和交流马达、致动器等等。
在一些实施例中，线性稳定器106可以附接到药物贮存器120和/或推动轴114可以抵靠止动部140，从而延伸TSA 152使得止动部140相对于贮存器120轴向移动。止动部140相对于贮存器120的轴线反向力(例如，由于止动部和贮存器之间的摩擦和/或由于流动阻力产生的)通过线性稳定器106和贮存器120之间的线性力在盒153内可选地平衡。
在一些实施例中，马达108可以将扭矩施加于传动轴110。可选地，防旋转引导部104可以附接到药物贮存器120，从而启动马达108以使推动轴114相对于传动轴110轴向移动。传动轴110和推动轴114之间的摩擦通过马达108和防旋转引导部104之间的反向扭矩可选地平衡，从而TSA 152用作线性致动器，其将净线性力(和/或微不足道的扭矩)施加到与药物接触的装置的部分(例如止动部140和/或贮存器120)上。
在一些实施例中，线性稳定器106、传动轴110、中间轴112、推动轴114和/或防旋转引导部104的任何一个或者全部可以被部分和/或全部定位在贮存器120的内部。可选地或者另外，线性稳定器106、传动轴110、中间轴112、推动轴114和/或防旋转引导部104的任何一个或者全部当TSA 152收缩时可以被全部或部分定位在贮存器120的外部，和/或当TSA152延伸时可以全部或部分移动到贮存器120中。
在一些实施例中，中间轴112和/或防旋转引导部104可以轴向移动。例如，中间轴112和/或防旋转引导部104可以移动到贮存器120中和/或从贮存器120移出。可选地，中间轴112可以浮动。在当前公开中，在一些构造中(例如当TSA 152部分延伸时)，浮动部件的位置可以是不确定的。例如，该部件可以移动而无需改变TSA 152的长度。例如，TSA 152的部件的移动的次序可以是不固定的。可选地，传动轴110可以是内轴并且推动轴114可以是外轴。可选地或者另外，传动轴110可以是外轴并且推动轴114可以是内轴。本发明的任意部件或者全部部件可以由塑料和/或金属和/或另一种材料制成。
驱动止动部
图2是图解根据本发明的实施例的驱动止动部的方法的流程图。在一些实施例中，TSA可以通过旋转单个轴210和/或通过防止单个轴的旋转来延伸或者缩回大于它的最小长度的100％。例如，TSA可以通过旋转210传动轴打开。可选地，近端传动轴可以位于最接近远端推动轴。例如，传动轴可以通过安装在装置上的马达相对于药物输送装置旋转210。例如，传动轴的旋转210可以相对于药物输送装置的壳体和/或相对于马达的架。可选地，在传动轴旋转的同时，推动轴可以被防止旋转202。例如，防旋转引导部可以防止推动轴相对于药物输送装置壳体和/或相对于马达和/或相对于马达架旋转。传动轴相对于推动轴的旋转210使TSA和/或推动轴和/或止动部可选地延伸。
在一些实施例中，中间轴可以轴向浮动。例如，当TSA延伸时，中间轴可以或者随着推动轴线性延伸212和/或随着传动轴旋转213。可选地，对于TSA的一些长度，中间轴的位置可以是不确定的。例如，旋转210传动轴可以例如将中间轴延伸212到贮存器中(例如，当传动轴旋转得比中间轴快时和/或借助于传动轴到中间轴的螺纹联接)。可选地，将中间轴延伸212到贮存器中同时将推动轴延伸214到贮存器中。可选地或者另外，旋转210传动轴可以使中间轴旋转213。可选地，旋转213中间轴使推动轴延伸214到贮存器中(例如借助于传动轴到中间层的螺纹联接)。中间轴的旋转和/或延伸可以同时和/或连续发生。
在一些实施例中，防旋转引导部可以轴向浮动。例如，当TSA延伸时，防旋转引导部可以或者与推动轴一起延伸204(例如相对于贮存器轴向移动和/或轴向移动到贮存器中)，和/或防旋转引导部可以相对于贮存器保持固定，和/或推动轴可以相对于防旋转引导部轴向延伸214。可选地，对于TSA的一些长度，防旋转引导部的位置可以是不确定的。在一些实施例中，推动轴可以旋转，同时TSA的另一元件被防旋转地稳定(防止例如相对于药物输送装置壳体和/或马达旋转)。
止动部驱动器的装配和/或安装
图3是图解根据本发明的实施例的装配止动部驱动器的方法的流程图。例如，止动部驱动器可以适配用标准制药设备可填充的贮存器(例如，在具有为标准注射器和/或盒制成的填充设备的现有净化室中)。可选地，止动部驱动器接合位于贮存器内的任意位置处的止动部。在一些实施例中，止动部驱动器可以与部件咬合在一起而装配。部件可选地由诸如塑料的铸模材料制成，例如聚氧化亚甲基(POM)树脂。
在一些实施例中，供给320药物贮存器。可选地，贮存器可以被预填充。例如，贮存器可以利用标准填充设备填充。例如，贮存器可以具有任意截面的圆柱形和/或管状本体。例如，本体可以为直圆柱体的形式。贮存器可选地包括内部腔体。可选地，内部腔体可以是任意形状。例如，内部腔体可以具有超过它的至少一半长度和/或超过它的至少90％的长度的平滑壁。例如，贮存器的腔体可以大体上为超过它的至少一半长度和/或超过它的至少90％的长度的直圆柱体。例如，内部腔体可以在超过它的至少一半长度和/或超过它的至少90％的长度上与贮存器的外壁同轴。例如，腔体的截面可以在超过它的至少一半长度和/或超过它的至少90％的长度上是均匀的。可选地，贮存器可以包括远端开口。例如，贮存器的远端可以包括套管，例如皮下注射针和/或用于这种情况的架。可选地或者另外，贮存器的远端和/或远端开口可以包括例如隔板的密封部，和/或例如针头盖的无菌盖。贮存器的近端可以包括近端开口。可选地，近端开口可以大于远端开口。例如，近端开口的截面面积可以介于远端开口的截面面积的5至50倍之间，和/或远端开口的截面面积的50至500倍之间。可选地，截面开口可以是倾斜的和/或可以平稳连接到贮存器的内部腔体。可选地，止动部可以插入近端开口中。可选地，止动部可以密封和/或保持贮存器的内容物的无菌。可选地，止动部的位置可以依赖于贮存器的内容物的体积而改变。可选地，贮存器的近端可以包括凸缘。例如，凸缘可以从贮存器的外周伸出20％至100％之间。例如，凸缘可以从近端开口的内壁延伸1mm和2cm之间。可选地，贮存器作为单个完整单元可以例如由模压玻璃或者塑料和/或切割和/或处理的管材制成。
在一些实施例中，用简单的方式装配TSA。可选地，装配可以是单向的。单向装配可以包括例如，从TSA的相同端部插入全部或者最多的轴。单向装配可以包括例如在相同方向上螺纹拧入一些大多数和/或全部轴。可选地，在装配期间无需部件倒转方位就可以完成装配，和/或无需其它复杂工作，例如焊接、铆接、塑性变形等等而添加。
在一些实施例中，一系列轴可以一起螺纹拧入。例如，内部轴的前端可以通过较外部轴的后端(远端)插入。例如，内部轴的前端可以螺纹拧入较外部轴和/或较外部轴的远端中。如这里所使用的，术语/短语前端意思是在延伸状态下内轴从其突出的TSA的端部。如这里所使用的，术语/短语后端意思是在延伸状态下外轴从其突出的TSA的端部。如这里所使用的，术语/短语螺纹拧入意思是朝着引导方向螺纹连接较内部轴(在一些实施例中，螺纹拧入用于装配和/或延伸TSA)。如这里所使用的，术语/短语脱螺纹意思是朝着外轴的后面螺纹连接较内部轴(在一些实施例中，脱螺纹用于收缩TSA)。可选地或者另外，在一些实施例中，脱螺纹可以用于装配和/或延伸TSA，和/或螺纹拧入可以用于收缩TSA。可选地，最内轴的前端可以包括紧固件和/或最外部轴的后端可以包括紧固件。
在本发明的一些实施例中，基于延伸TSA阻止轴的脱离和/或分离。例如，TSA的内部轴在它的后端可以包括凸缘和/或阶梯。凸缘可以防止与较外轴脱离。可选地或者另外，凸缘可以由不同的几何形状的突起替代。
在一些实施例中，TSA可以从倒转的延伸位置简单单向装配。装配的TSA可以通过延伸任意阻止拆卸。
在一些实施例中，TSA由模制部件装配。在一些实施例中，模制提供高度精确的部件几何形状。模制部件在装配期间可与最小的变型任意装配。例如，TSA的组件可以包括最小粘着力或者无粘着力的部件，和/或通过热和/或超声波工具和/或通过力(例如通过卷曲)改变部件几何形状。模制部件可以可选地包括便于适当定位的特征。模制部件可以可选地包括嵌入的连接器和/或紧固件(例如锁扣、锁闩、抓钩、钩、扣等等)。在一些实施例中，部件可以由塑料模制。例如，塑料可以包括低摩擦材料。这种材料的实例包括聚对苯二甲酸丁二酯(PBT)树脂(例如可从泰科纳(TICONA)获得的
Figure BDA0001004203680000121
树脂)和/或POM树脂(例如杜邦(DuPontTM)的迭尔林(
Figure BDA0001004203680000122
树脂)。
在一些实施例中，内部轴可以利用后凸缘和/或突起模制在单个件中。凸缘和/或突起可以可选地阻止轴的无意分离。在一些实施例中，部件可以利用紧固件模制在单个件中。在一些实施例中，部件可以利用螺纹止动部和/或干涉元件模制在单个件中。
在一些实施例中，组件的轴的一些或者全部可以可选地从端盖拆卸而供给。例如，一些或者全部轴和/或端盖可以包括紧固件。轴可以可选地装配有凸缘，该凸缘防止由于过度延伸而导致的拆卸。例如，内部轴可以在后端上具有凸缘。可选地，凸缘和/或紧固件可以是固有的。例如，轴和/或盖可以利用紧固件和/或凸缘模制在单个件中。
在一些实施例中，一些或者全部轴可以通过反向延伸而装配在一起。例如，内部轴的前端可以插入较外部轴的后端。例如，内部轴可以从拆卸(反向延伸)位置通过它的收缩位置离开配合轴的前端螺纹拧出到延伸位置。在一些实施例中，防止轴在延伸状态下分离的凸缘也可以防止轴在延伸状态下附接并且将轴螺纹拧入到收缩状态。
在一些实施例中，在内轴的前端上可以供给紧固件。一旦内轴的前端延伸超过配合轴，端盖(例如驱动器和/或致动器)可以固定到紧固件。可选地，可以供给干涉元件。例如，干涉元件可以包括凸缘和/或可以包括一个或多个突起，该凸缘阻碍脱螺纹回到反向的延伸位置，该突起防止轴和端盖之间的碰撞产生的螺纹锁止。
现在参照图3，该图图解用于装配TSA的示例性方法。在一些实施例中，内轴(例如，图4A所示的传动轴410)的前端可以螺纹拧入310中间轴(例如，图4A的中间轴412)的后端。可选地，内轴的前端可以通过中间轴始终被螺纹拧入直到内轴的前端从中间轴的前端突出。
在一些实施例中，中间轴的前端与内轴一起可以螺纹拧入312远端外轴(例如，图4A的推动轴414)的后端。螺纹拧入312可以继续直到内轴的前端从外轴的前端突出。可选地，组件可以仅包括两个轴和/或三个轴和/或多于三个轴(例如四个、五个、六个或更多轴)。在一些实施例中，不管轴的数量，轴的组件可以具有从前端突出的内轴的紧固件和从后端突出的外轴的紧固件。
在一些实施例中，致动器盖(例如，图4A的远端盖424)可以附接324到外轴的紧固件。例如，致动器盖可以包括注射器止动部和/或附接到注射器止动部的适配部。通过伸缩组件致动的注射器止动部的实例可以例如在卡比利亚(Cabiri)的国际专利申请公开第WO/2011/090956号和/或格罗斯(Gross)的美国专利申请公开第2009/0093792号中找到，它们的全部内容通过引用而结合在本文中。
在一些实施例中，外轴可以连接304到第一防旋转引导部(例如图4A的防旋转引导部404)。例如，第一引导部和外轴可以相对于彼此轴向移动，但是可以防止绕轴线相对于彼此的旋转。可选地，第一引导部可以连接302到第二引导部(例如，图4A的稳定器402)。例如，第二引导部和第一引导部可以相对于彼此轴向移动，但是可以防止绕轴线相对于彼此的旋转。在一些实施例中，线性稳定器也是防旋转稳定器。在一些实施例中，第一防旋转引导部和第二防旋转引导部可以收缩，从而传动轴的近端突出超过引导部的近端。传动轴的近端可以连接到传动装置。例如，传动轴410的近端可以插入326通过齿轮中的狭缝(例如，传动轴410的连接器432a可以插入图4A的盒齿轮426的狭缝432b中)。可选地，组件的近端将通过近端盖结合在一起327(例如，在图4A中，端盖438可以咬合保持器437，该保持器437可以保持到在传动轴410的近端上的紧固件430)。
在一些实施例中，在装配之后，TSA可以收缩和/或重绕328到停止位置(例如通过脱螺纹)。可选地，TSA可以包括一个或多个螺纹止动部。例如，螺纹止动部可以包括在旋转轴(例如中间轴412和/或传动轴410)上和/或在端盖(例如致动器盖424)上的干涉元件和/或突起。一个或多个干涉元件可以在TSA收缩时在预定点处相遇并且防止进一步的相对旋转。例如，干涉元件可以防止在内轴的脱螺纹方向上相对于外轴的旋转，从而防止进一步收缩和/或螺纹锁止(例如，参见图4A的干涉元件436和434)。
在一些实施例中，止动部驱动器附接到药物贮存器以形成盒。例如，线性稳定器(例如稳定器402)可以附接到贮存器(例如，连接器421a可以附接到凸缘421b，如图4A和图4C所示)。防止线性稳定器的线性移动的连接器可以称为线性连接器。例如，线性连接器421a防止稳定器402相对于盒420的线性移动。可选地或者另外，止动部驱动器和/或线性稳定器可以附接到药物输送装置的壳体(例如，如图6A-6C中所示)。
在一些实施例中，在将盒插入药物输送装置之前，TSA可以延伸314以接触贮存器中的止动部。在TSA接合到输送装置之前止动部与TSA的接触可以使得易于确定注入的药物的体积(基于与马达和/或传动轴的转数成比例的止动部已经移动的距离[例如可以调整在全部轴上的螺纹的螺距以便转数与排出的体积的比是常数])。可选地或者另外，在一些实施例中，贮存器和/或止动部驱动器和/或完整的盒可以在TSA已经接触止动部之前插入药物输送装置中。例如，药物输送装置的马达可以首先驱动传动轴以延伸314TSA直到它接触止动部然后继续驱动传动轴以排出药物。允许TSA不接触止动部直到插入药物输送装置中之后，可选地使得盒的生产和/或装运简单化。在一些实施例中，药物输送装置可以输送盒的整个内容物而无需跟踪输送的数量。例如，在有些情况下，盒可以精确地包括一次剂量。在一些实施例中，药物输送装置可以包括传感器(例如负载传感器)，该传感器传感到何时TSA朝着止动部延伸314和/或何时TSA接合止动部和/或何时TSA逆着阻力推动止动部(例如排出药物)。可选地或者另外，止动部可以放置到贮存器中的精确位置上，从而正在安装时TSA接触止动部。例如，没有必要在安装之后延伸314TSA以接触止动部。
在一些实施例中，防旋转引导部附接322到药物输送装置的壳体。例如，在图4D中，当盒插入装置中时，连接器421a适配到狭缝421c中从而防止稳定器402相对于药物输送装置422的壳体和/或附接到其的马达408(例如参见图4E)的旋转。在一些实施例中，当盒453插入输送装置422中时，壳体422可以接合盒。例如，干涉元件439可以咬合到盒453和/或将453保持在输送装置中。可选地或者另外，防旋转引导部可以附接到贮存器和/或贮存器可以附接到输送装置的壳体和/或马达。防止防旋转稳定器的旋转移动的连接器可以称为防旋转连接器。例如，防旋转连接器421a防止稳定器402相对于壳体输送装置422的旋转移动。
具有滑动套筒防旋转引导部的止动部驱动器
现在参照图4A，附图是图解包括在反向延伸状态下的滑动套筒的贮存器和止动部驱动器的实施例的分解图。在一些实施例中，贮存器420用止动部440供给密封。可选地，利用标准填充设备，贮存器420被预填充和/或止动部440被密封在适当的位置。在一些实施例中，止动部驱动器450可以由简单的部件装配和/或与部件咬合在一起。
在一些实施例中，贮存器420可以包括近端开口454，和/或远端开口456。止动部440可选地密封贮存器420的腔体。可选地，取决于例如药物远端到止动部440的体积和/或收缩的止动部驱动器近端到止动部440所需要的空间，止动部可以放置在任意纵向位置上。
在一些实施例中，贮存器420可以包括远端开口456和/或近端开口454。例如，近端开口454可以足够大以插入止动部440。可选地，远端开口可以配置有用于针和/或隔板的颈部和/或架。
在一些实施例中，止动部驱动器450包括TSA 452。TSA 452从反向延伸状态(例如，如图4A中所示)任意装配。例如，传动轴410的近端插入中间轴412中，直到传动轴410的外螺纹411a接合在中间轴412的近端附近的内螺纹411b。可选地，传动轴410螺纹穿过中间轴412直到传动轴410的近端突出中间轴412的近端。可选地，组合装配的中间轴412和/或传动轴410的近端插入推动轴414中，直到中间轴412的外螺纹413a接合在推动轴414的近端附近的内螺纹413b。可选地，中间轴412螺纹通过推动轴414直到传动轴410的近端突出推动轴414的近端。可选地，锁止和/或咬合元件防止TSA 452被拆卸。例如，远端盖424可以包括干涉元件，该干涉元件锁止(例如咬合适配)约束元件，例如推动轴中的孔。可选地或者另外，远端盖424可以防止TSA 452的脱螺纹。例如，一旦远端盖424在适当的位置，当传动轴410从中间轴412脱螺纹时，远端盖424上的接收器通过防止进一步脱螺纹的推动轴414上的配合的干涉元件螺纹锁止保护器阻止进一步移动。例如，一旦远端盖424在适当的位置，当中间轴412从推动轴414脱螺纹时，中间轴412的远端上的干涉元件螺纹锁止保护器干涉元件436通过防止进一步脱螺纹的远端盖424上的配合的干涉元件被阻止。可选地，TSA可以包括多于三个轴。例如，可以有多于1个中间轴。在一些实施例中，传动轴410可以是内轴并且推动轴414可以是外轴。可选地或者另外，传动轴可以是外轴并且推动轴可以是内轴。在一些实施例中，装配的TSA 452被装配到止动部驱动器450中。
在一些实施例中，TSA 452接合到防旋转引导部和/或传动元件。例如，包括接合到轨道415b的突起415a的联接部可以将推动轴414链接到防旋转引导部404。防旋转引导部任意接合到稳定器402。例如，防旋转引导部404的突起405a在稳定器402中可以接合到轨道405b(例如参见图4B)。可选地，推动轴414、防旋转引导部404和/或稳定器402可滑动接合。例如，推动轴414、防旋转引导部404和/或稳定器402可以相对于彼此轴向滑动，但是防止一个相对于另一个绕轴线旋转。在一些实施例中，引导元件可以咬合在一起。例如，轨道415b和/或轨道405b可以包括干涉元件(例如在其远端和/或在其近端)。通过在插入突起415a时使得防旋转引导部404弹性变形，突起415a越过远端干涉元件任意插入轨道415b中。一旦突起415a在轨道415b内，防旋转引导部404任意返回到它的原来形状，和/或通过干涉元件防止突起415a退出轨道415b。可选地或者另外，推动轴414可以被弹性挤压以在它们适配到轨道415b中处缩回突起415a。通过在插入突起405a时使得防稳定器402弹性变形，突起405a越过远端干涉元件任意插入轨道405b中。一旦突起405a在轨道405b内，稳定器402任意返回到它的原来形状，和/或通过干涉元件防止突起405a退出轨道405b。可选地或者另外，旋转引导部404可以被弹性挤压以在它们适配到轨道405b中处缩回突起405a。
在一些实施例中，一旦TSA 452连接它的防旋转引导部(例如防旋转引导部404和/或稳定器402)，引导部一起滑动和/或压缩，从而传动轴410的近端突出稳定器402中的近端开口403和/或直到传动轴410的联接部(例如肩部轴承406)相对于稳定器402静止。可选地，传动轴410在开口403内自由旋转。可选地，传动元件包括例如盒齿轮426。传动元件任意接合到传动轴410的突出近端部分。例如，非旋转配合部432a可以插入通过盒齿轮426的狭缝和/或接收器432b，从而传动轴410固定接合和/或对准到齿轮426和/或随着齿轮426旋转。可选地，紧固件和/或咬合元件防止拆卸止动部驱动器450。例如，端盖438可以咬合保持器437，在图4A中，该保持器437可以保持到传动轴410的近端上的紧固件430。在一些实施例中，装配的止动部驱动器450例如通过齿轮426相对于稳定器402的旋转再绕和/或传动轴410相对于推动轴414旋转。可选地，旋转在使TSA 452脱螺纹的方向上，直到它已经收缩和/或直到通过螺纹停止元件停止脱螺纹。收缩的止动部驱动器450任意附接到贮存器420以形成盒453(例如参见图4C)。
现在参照图4B，附图是图解在延伸状态下的止动部驱动器450的实施例的截面图。例如，在装配止动部驱动器450之后，盒齿轮426相对于稳定器402旋转和/或传动轴410相对于推动轴414旋转。可选地，例如如图4B所示，旋转在传动轴410和/或中间轴412近端通过推动轴414的近端螺纹拧入从而延伸TSA 452到延伸构造的方向上。
在一些实施例中，轴可以包括防止在螺纹拧入和/或延伸TSA期间轴的脱离的构件。例如，传动轴410包括后凸缘482并且中间轴412包括后凸缘484。当轴410达到全部延伸时，凸缘482任意接触中间轴412的内部螺纹411b从而防止进一步延伸。当轴412达到全部延伸时，凸缘484任意接触推动轴414的内部螺纹413b从而防止进一步延伸。可选地或者另外，元件防止由于超过延伸而导致的轴的脱离(例如凸缘482和/或484)。可选地，防止超过延伸的元件可以包括干涉元件和/或突起和/或任何几何形状的另一元件，例如环形元件。
在一些实施例中，线性稳定器将阻止传动轴在近端方向上移动。例如，肩部轴承406支撑稳定器402。可选地，传动轴410可以绕止动部驱动器450的纵轴相对于稳定器402旋转，但是防止传动轴410在近端方向上相对于稳定器402轴向移动。
图4C是根据本发明的实施例的包括贮存器420、止动部440和/或止动部驱动器450的盒453的透视图。在一些实施例中，装配的止动部驱动器450可以附接到贮存器420。例如，连接器421a可以将稳定器402夹紧到贮存器420的后凸缘421b上。可选地，稳定器402是线性稳定器，将TSA 452线性稳定和/或保持在贮存器420的腔体内和/或防止驱动器410的近端移动(例如借助于肩部轴承406，如图4B所示)。当TSA 452延伸时，推动轴414相对于稳定器402和/或贮存器420向远端移动，直到推动轴414接触止动部440。TSA 452的进一步延伸向远端推动止动部440和/或排出药物。
在一些实施例中，盒453作为单个元件插入药物输送装置中。可选地，当止动部驱动器450安装到收缩状态下的盒453时，驱动器450的大部分(例如，介于50％至75％之间和/或介于75％至90％之间和/或介于90至100％之间)定位在贮存器420内。可选地或者另外，当驱动器处于收缩状态和/或当驱动器附接到贮存器时，止动部驱动器的大部分或者全部可以在贮存器的外侧。
图4D是根据本发明的实施例的盒453插入药物输送装置422中的透视图。在一些实施例中，盒插入药物输送装置422中将打开贮存器420与装置422之间的流体流动路径，和/或将盒453的传动元件接合到装置422的马达，和/或旋转地稳定盒。例如，盒453线性插入装置422中的引导路径中。在插入盒453时，装置422内部的套管穿透盒453的远端上的隔板从而创建装置422和贮存器420之间的流体路径。可选地或者另外，盒453的远端上的套管可以穿透装置422的隔板形成流体路径。可选地或者另外，盒453的远端上的皮下注射针直接插入受试者。
