具体实施方式
在本发明的一些实施例中,本发明涉及一种用于将药筒装载到药物装置中的方法和系统,并且具体地但非排他地,涉及一种用于促进药筒的适当稳定的系统和方法。
概述
本发明的一些实施例的一个方面涉及用于将药筒稳定到固定方向的系统。药筒稳定系统可选地允许沿锁定方向和/或另一方向将药筒引入药筒座架中和/或将药筒重新定向到锁定方向和/或使药筒在锁定方向中稳定。
在一些实施例中,稳定系统将被构造为避免干涉药筒的插入。例如,稳定系统可以允许将药筒沿锁定方向和/或沿其他方向和/或沿任意方向插入。
在一些实施例中,药筒被锁定的机构将不适用于药筒的插入。例如,对于纵向插入的药筒,干涉力可以阻止围绕纵向轴线的旋转,而不是纵向移动。替代地或另外地,锁定机构的力可以阻止插入轨迹的仅一部分中的插入。例如,插入阻力可以是在插入过程的开始或结束时。可选地,抵抗插入的力可小于抵抗锁定方向的力的1/100和/或插入阻力可介于锁定力的1/100至1/50之间,和/或插入阻力可介于锁定力的1/50至1/10之间,和/或插入阻力可以介于锁定力的1/10至1/2之间。例如,插入阻力可以施加到小于插入轨迹的1/2和/或小于插入轨迹的1/4和/或小于插入轨迹的1/8和/或小于插入轨迹的1/20。
在一些实施例中,药筒稳定系统可以辅助药筒插入。例如,药筒稳定系统可以添加当将药筒完全插入药物输送装置时停止的阻力。例如,稳定系统可以用作向用户指示药筒被完全安装的触觉指示。例如,当干涉元件被偏转时,干涉元件可以施加范围在200g到400g之间和/或在400g到800g之间和/或在800g到2000g之间的力。例如,干涉元件可以在0.5mm到1.0mm之间和/或在1.0mm到1.5mm之间和/或在1.5mm到3mm之间偏转。例如,干涉元件与互补干涉元件互锁时的干涉元件的偏转力和/或距离与干涉元件和互补干涉元件重叠时的干涉元件的偏转力和/或距离之间的比率可以在0到0.3之间和/或在0.3至0.6之间和/或在0.6至0.9之间和/或在0.9至1.0之间。可选地,互锁的干涉元件可以保持药筒不动和/或稳定,以获得0至200g-cm和/或0至500g-cm和/或0至1000g-cm范围内的扭矩。在一些实施例中,由驱动器在柱塞上产生的轴向力例如在药物输送期间的范围在0.5kg至2kg和/或2kg至4kg和/或4kg至10kg之间。
在一些实施例中,在插入之后将药筒重新定向到最终和/或锁定位置。可选地,驱动药物输送的驱动器也将驱动药筒的重新定向。例如,驱动器可以向药筒施加扭矩。扭矩可以使药筒重新定向,直到稳定系统将药筒稳定在锁定方向。可选地,当药筒被锁定时,驱动器可以开始继续驱动药筒。
可选地,在锁定之后,驱动器的力可以执行与重新定向不同的功能。例如,一旦药筒被锁定和/或抵抗旋转,驱动器的扭矩就可以被转换成释放和/或输送药物的力和/或驱动用于排出的准备,例如推动柱塞驱动器和/或柱塞和/或刺穿隔膜。
在一些实施例中,锁定机构包括干涉元件。
可选地,当药筒未处于锁定位置时,干涉元件不会干扰移动。替代地或另外地,当药筒未处于锁定位置时,可以将干涉元件从锁定位置弹性地推出。替代地或另外地,当药筒不处于锁定位置时,干涉元件将在一个方向上产生力(例如,由于干涉元件的摩擦和/或弹性强制而导致的插入阻力),和/或干涉元件将在锁定位置产生不同的力(例如,阻止旋转)。在一些实施例中,非锁定位置可包括例如覆盖359度至300度方向和/或300度至200度之间和/或200度至100度之间和/或100度至50度之间和/或50度至2度之间的角度。
在一些实施例中,药筒将在其前导面和/或表面上包括干涉元件(前导面和/或表面可包括当将药筒插入输送装置时面向行进方向的表面)。例如,对于可选地向远侧推入药筒座架中的药筒,干涉元件可以可选地位于药筒的远侧面上。可选地,干涉元件不与互补元件互锁和/或不干扰药筒的插入,直到插入远端面以到达输送装置的互补干涉元件。例如,干涉元件可以在插入的最后1/2到最后1/10之间和/或插入的最后1/10到最后1/100之间的范围内的区域中相互作用。例如,干涉元件可以在插入的最后2cm到最后4mm之间的范围内和/或插入的最后4mm到最后0.4mm之间的区域中相互作用。
在一些实施例中,驱动器包括与药物贮存部的抗旋转连接。例如,柱塞和/或摩擦垫可以在贮存部的内壁和驱动器之间提供抗旋转摩擦。
在详细解释本发明的至少一个实施例之前,应理解,本发明不一定将其应用限于以下描述中阐述的和/或在附图和/或实施例中说明的构造细节和部件的布置和/或方法。本发明能够具有其他实施例或者能够以各种方式实践或实施。
稳定药筒的示例性方法的流程图
图1是根据本发明的实施例的插入和/或定向和/或锁定药筒的流程图。在一些实施例中,使用者将药物药筒沿任意方向插入102输送装置中。可选地,装置对药筒重新定向104,直到其到达锁定方向106并且锁定108。例如,驱动药物排出110的驱动器也驱动药筒的定向。
在一些实施例中,用户将药筒插入102到输送装置中。例如,药筒可包括纵向插入药筒座架中的管状贮存部。例如,药筒可包括注射筒和/或小瓶和/或安瓿。在一些实施例中,在输送期间,药筒可以以固定方向稳定在药筒座架中。然而,当用户沿任意方向插入药筒102时,可能希望装置正确地执行。此外,可以希望锁定机构不妨碍药筒插入。例如,基于摩擦的稳定可能妨碍药筒的插入。可选地,在使锁定机构脱离的同时插入药筒102。
在一些实施例中,用户启动装置。例如,启动装置可以包括激活103药物输送的驱动器。可选地,最初,例如当药筒处于解锁状态时,驱动器可能不会驱动药物的输送。例如,最初,驱动器可以驱动药筒的重新定向104。可选地,药筒将继续重新定向104,直到其到达锁定方向106和/或被锁定108。
在一些实施例中,在药筒被锁定108和/或处于其锁定方向106之后,输送驱动器将继续操作109。可选地,驱动器的继续操作109将药物排出110和/或将药物输送至受试者。
药筒稳定装置的实施例
图2A是根据本发明的实施例的药筒稳定系统的图示的框图。在一些实施例中,输送装置201包括容纳药物贮存部202的药筒座架204。例如,座架204可以在多于一个的可能方向上容纳贮存部202。可选地,当贮存部202处于锁定方向时,药筒和托座架上的互补干涉元件218和208分别互锁和/或将药筒锁定到锁定方向。可选地,当药筒处于非锁定方向时,干涉元件218和208重叠。可选地,当药筒处于非锁定方向时,干涉元件218和208中的至少一个弹性地移位。
在一些实施例中,输送装置201包括驱动器203。可选地,驱动器203驱动贮存部202在座架204中的重新定向。例如,驱动器203可以产生使贮存部202旋转的扭矩。可选地,扭矩可以例如通过使贮存部202绕座架204内的轴线旋转对药筒重新定向。可选地,当贮存部202达到特定方向(例如锁定方向)时,药筒上的干涉元件218与输送装置上的干涉元件208互锁和/或停止药筒相对于装置的重新定向。
在一些实施例中,当贮存部202被锁定时,驱动器203的进一步扭矩驱动药物的输送。例如,贮存部202可包括药物贮存部和/或用于从贮存部排出药物的泵。例如,驱动器203可以将柱塞推入贮存部中以从贮存部202排出药物。
在一些实施例中,驱动器203可以包括伸缩螺钉组件(TSA)和/或柱塞接口。例如,驱动器203可以包括马达(例如,DC电马达和/或无刷电马达和/或化学动力马达)。马达可选地在TSA和输送装置的底盘212之间施加扭矩。可选地,TSA将扭矩施加到柱塞上;柱塞可选地将扭矩施加到贮存部。例如,只要贮存部202可自由旋转,马达的扭矩就使贮存部202旋转。当贮存部202被互锁的干涉元件208和/或218锁定时,药筒产生反扭矩,该反扭矩被传输到TSA。可选地,TSA上的扭矩和反扭矩可以使TSA中的螺纹相对于彼此旋转,从而使伸缩组件扩展和/或驱动柱塞和/或排出药物。替代地或另外地,驱动器可以包括驱动排出的线性致动器和/或活塞组件。替代地或另外地,可以通过柱塞和贮存部的内壁之间的摩擦和/或通过摩擦元件(例如,接触贮存部的内壁的摩擦垫)和/或通过干涉元件在药筒和驱动器之间传递扭矩。
图2B是示出根据本发明的实施例的替代药物输送装置的框图。在一些实施例中,药物输送装置201可包括马达230。可选地,马达230驱动变速器205。例如,变速器205可将旋转能量传输到伸缩螺钉组件TSA 233。可选地,TSA 233连接到贮存部202的柱塞286。例如,来自马达230的扭矩可以使整个药筒(例如,包括变速器205、TSA 233、柱塞286和/或贮存部202)旋转。可选地或另外地,当防止贮存部202和/或柱塞286旋转时,旋转变速器205可以相对于TSA233的螺纹连接的第二部分在TSA 233的一部分上旋转。螺纹连接的部分相对于彼此的旋转可选地使TSA 233扩展和/或将柱塞286推入贮存部,例如驱动药物的排出。
与药筒接触的示例性表面
图3A-3D是根据本发明的实施例的药筒稳定系统的示意图。可选地,药筒可包括圆柱形贮存部302,其沿任意方向纵向插入输送装置中。圆柱形贮存部302可选地自由旋转,直到输送装置的干涉元件308与药筒上的互补特征互锁,从而阻止药筒相对于输送装置进一步旋转。
在一些实施例中,贮存部302包括凹槽317和/或互补干涉元件,例如突出部分318,其构造成与输送装置上的干涉元件308互锁。可选地,干涉元件308是弹性的。例如,当凹槽317未与干涉元件308对准时和/或当突出部分318与干涉元件308重叠时(例如,如图3A和图3B所示),则元件308可以弯曲到药筒302的路径之外,从而允许将药筒302插入输送装置和/或允许药筒302相对于输送装置旋转。
在一些实施例中,当凹槽317与元件308对准时,元件308和突出部分318互锁。例如,元件308可以朝向凹槽317偏压,使得当它们对准时,元件308卡入凹槽317中和/或互锁(例如,如图3C和/或图3D所示)。可选地,互锁可允许药筒相对于装置纵向移动。可选地,互锁可以阻止药筒相对于装置的进一步旋转。
图4A和图4B是根据本发明的实施例的替代的药筒稳定系统的示意图。在一些实施例中,药筒包括在药筒的前导面上的互补干涉元件。例如,药筒可以向远侧插入药筒座架中。药筒的互补干涉元件可位于药筒的远侧面上。例如,当药筒接近完全插入输送装置时,远端面可能遇到输送装置的干涉元件。可选地,干涉元件不会抑制(和/或影响)药筒插入的开始。
在一些实施例中,药筒可以包括具有近侧凸缘416的贮存部402。可选地,输送装置上的干涉元件408与药筒上的互补元件相互作用。例如,凸缘416的远侧面419可以包括凹槽和/或突起,当药筒处于特定方向时,该凹槽和/或突起与元件408互锁。例如,当元件408与突起重叠时,元件408或突起可以弹性地移位。例如,当元件408与凹槽对准时,它可以卡入凹槽中和/或与突起互锁和/或锁定贮存部402的方向。可选地,元件408将在最后1毫米的药筒插入期间接触凸缘416。例如,在插入结束时,元件408的弹力可以将药筒从药筒座架向外推出,直到药筒到达完全插入位置。在完全插入的位置,药筒可以固定在适当位置,固定药筒可以包括与元件408的向外力相反的力。例如,元件408的阻力和/或阻力的无效可以用作向用户显示已经完全插入药筒的触觉信号。
在一些实施例中,药筒包括TSA 403。例如,TSA 403可以连接到变速器,例如包括驱动齿轮405。
可选地,当将药筒插入输送装置时,变速器连接到驱动TSA以使药筒旋转和/或排出药物的马达。
药筒的示例性稳定和/或药物的排出
图5是根据本发明的实施例的插入和/或定向和/或锁定药筒的图示的流程图。在一些实施例中,锁定机构不会影响药筒插入,直到药筒接近插入结束。在插入结束时,输送装置的干涉元件可选地接触药筒的互补表面和/或元件。例如,互补表面可以是具有与干涉元件互锁的部分的表面和/或具有便于对药筒重新定向直到表面的互锁部分接触干涉元件的部分的表面。
在一些实施例中,将药筒自由地插入502到输送装置中。
可选地,药筒可以沿各种和/或任意方向插入502。例如,对于具有圆柱形贮存部的药筒,药筒可选地以围绕贮存部的纵向轴线的任何旋转方向插入。可选地,稳定系统不会干扰插入,至少插入至其完全插入深度的50%至90%和/或90%至97%之间和/或97%至99%之间。例如,稳定系统可能不会干扰药筒的定向和/或在将药筒插入所述深度之前对药筒施加力。可选地或另外地,稳定系统可以在插入的开始部分上施加平均力,该平均力小于插入的最后部分上的平均力的1/2和/或小于1/10和/或小于1/100。
在一些实施例中,在插入的初始部分之后,在插入的最后部分期间,药筒可以接触524稳定系统的干涉元件。例如,插入的初始部分可以在插入的50%和插入的90%之间和/或在完全插入的深度的90%至95%和/或95%至99%和/或大于99%的范围内。例如,在药筒接触524干涉元件之后,元件可以产生对进一步插入的阻力和/或向外力。例如,向外的力可以将药筒从药筒座架中推出。可选地,当将药筒完全插入时,它可以固定526在药筒座架中。例如,固定526可以抵抗和/或废除与干涉元件的接触526的向外力。
可选地,由与干涉元件接触524产生的阻力可以为使用者提供作为药筒接近完全插入和/或未达到完全插入的标志。可选地,固定526可以为用户提供药筒正确和/或完全插入的标志。
在一些实施例中,在药筒完全插入502和/或固定526之后,用户可将药物输送装置放置在输送部位上和/或激活503装置。可选地,当装置处于活动状态并且药筒处于非锁定方向时[判定框506中否](例如,药筒座架中的干涉元件未对准和/或不与药筒上的互补特征互锁和/或输送装置上的干涉元件与药筒上的干涉元件重叠),然后干涉元件中的一个可以弹性地移位520。例如,弹性位移520可以通过干涉元件的弹性变形,和/或干涉元件可以具有弹性地变形的弹性支座架(例如,弹簧和/或弹性接头)。例如,位移可以由干涉元件与互补干涉元件的重叠引起。可选地,当药筒处于非锁定方向时[判定框506中否],驱动器对药筒的动作可以对药筒重新定向504(例如,旋转)。可选地,驱动器继续对药筒相对于输送装置重新定向504,直到药筒到达锁定方向。
在一些实施例中,当药筒处于锁定方向时[判定框506中是],药筒和/或输送装置上的干涉元件可以互锁522。互锁522可以将药筒在锁定方向上定向地锁定508。可选地,当药筒被定向锁定508时,驱动器可以继续操作109。例如,当药筒处于定向锁定508时,驱动器的继续操作109可以引起药物的输送和/或排出110。

图6是包括根据本发明实施例的药筒稳定系统的药物输送装置的透视剖视图。在一些实施例中,贮存部装配到药筒座架中。当插入贮存部时,前导面可选地接触输送装置的干涉元件。可选地,在一些方向中,前导面上的突起接触干涉元件和/或使干涉元件弹性地移动。
可选地,在一些方向上,前导面上的凹陷接触干涉元件。例如,凹陷和/或突起可以包括互补的干涉元件,其可选地与输送装置的干涉元件互锁和/或锁定贮存部的方向。
在一些实施例中,当贮存部几乎完全被插入时,输送装置的干涉元件608接触包括互补元件618的前导面619。例如,面619可以包括突起和/或凹陷617(例如,互补干涉元件618可以包括面619中的突起)。当干涉元件608接触面619时,元件608弹性地移位。例如,当元件608接触面619时,元件608向远侧弯曲。可选地,移位元件608导致对药筒插入的阻力。在一些实施例中,在接触元件608之后进一步插入贮存部使元件608进一步移动和/或激活将药筒固定在药筒座架中的纵向固定机构。
在一些实施例中,药筒的贮存部602包括连接器。例如,贮存部602包括隔膜638。可选地,输送装置650包括互补连接器,例如中空针636。
可选地,当药筒到达其锁定位置时,针636刺穿隔膜638并且在贮存部602和输送装置650之间形成流体路径。
在一些实施例中,药物输送装置650包括闭合元件。例如,药物输送装置650可以包括到药筒座架604的门640。例如,门640围绕轴640旋转以打开和/或关闭。
在一些实施例中,封闭元件,例如门640可以包括输送装置的驱动器的部分。例如,门640包括第二轴642,其可选地支撑药筒和输送装置650之间的连接。例如,连接可包括将药筒的TSA连接到输送装置650的马达的齿轮。示例性地示出了装置650和/或贮存部602的驱动系统,例如在图7中更详细地示出。
在一些实施例中,药筒包括凸缘616。例如,当将贮存部602完全插入座架604和/或将贮存部602纵向固定到座架604中时,装置650中的闩锁可阻挡凸缘616。
图7是药物输送装置650的示意性近端横截面图,其包括根据本发明实施例的药筒稳定系统。在一些实施例中,输送装置650包括马达730。例如,马达730通过变速器705连接到TSA 703。可选地,当将马达730连接到TSA703时,马达730使TSA703旋转。
在一些实施例中,马达730安装到输送装置650的底盘612。可选地,马达730使齿轮786相对于底盘612旋转。另一个齿轮784可选地安装在门640的轴641上。例如,当关闭门640时(例如,如图7所示),齿轮784在齿轮786和变速器705之间互连。可选地,当齿轮786连接到变速器705时,旋转齿轮786使TSA 703相对于底盘612旋转。
在一些实施例中,TSA 703旋转地互锁到贮存部602。
可选地,当贮存部602可相对于底盘612旋转时,旋转变速器705使贮存部602旋转。可选地或另外地,当贮存部602相对于底盘612旋转锁定时,旋转变速器705使TSA703的一端相对于TSA703的另一端旋转。使TSA703的一端相对于TSA703的另一端旋转可选地导致TSA703扩展或收缩。例如,使TSA703扩展可将柱塞推入贮存部和/或排出药物。
在一些实施例中,闩锁788将药筒固定到座架604中。例如,当将药筒插入座架604时,闩锁788向下弯曲以允许凸缘616进入座架604。可选地或另外地,当将药筒完全插入座架604时,闩锁788向上扣合,将凸缘616锁定就位和/或将药筒固定在座架604内。可选地,闩锁788产生反作用力,该反作用力至少部分地抵抗了对干涉元件608的弹性位移的插入的阻力。
图8A和图8B是药物输送装置650的透视剖视图,其包括根据本发明实施例的药筒稳定系统。在一些实施例中,当药筒的前导面619接触干涉元件608时,面619和/或干涉元件608可弹性地移位。可选地,当药筒上的干涉元件618与输送装置650上的互补元件608互锁时,例如当干涉元件608与面619上的凹口617重叠时,可发生弹性位移。可选地或另外地,药筒上的干涉元件618不与输送装置上的互补元件608对准,例如,当干涉元件与突起重叠时,可能发生弹性位移。弹性位移力可以向用户提供触觉反馈,帮助他知道何时药筒已经完全插入。在一些方向中,元件608和/或618可以稳定药筒的方向。
图8A示出了本发明的示例性实施例,其中贮存部602完全插入座架604中。在图8A中,可选地,贮存部602被定向成使得干涉元件608和618不对准。例如,干涉元件608可以通过药筒的面619上的突起重叠和/或弹性移位。在一些实施例中,当将贮存部602完全插入座架604时,闩锁788将凸缘616固定到输送装置中。
在一些实施例中,贮存部602的前导面619上的突起推动干涉元件608和/或弹性地移动元件608。元件608可选地迫使贮存部602向后,为用户提供触觉阻力。
可选地,当干涉元件608未与干涉元件618对准时,贮存部602可绕其轴线自由旋转。
在一些实施例中,驱动器,例如TSA 703使贮存部602旋转。可选地,贮存部602旋转直到干涉元件608与干涉元件618对准。可选地或另外地,可以将贮存部602沿干涉元件608和618已经对准的方向插入到座架604中。
在一些实施例中,例如,如图8B所示,当干涉元件608与元件618对准时,干涉元件608卡入面619的凹槽和/或凹口617中和/或与互补干涉元件618互锁和/或锁定贮存部602的方向。
可选地,干涉元件608在与元件618对准时比在与元件618重叠时更少移位或不移位。例如,当干涉元件对准时,弹性位移和/或弹力可在当元件未对准时(例如,当它们重叠时)的位移的50%至90°之间的范围内和/或在20%至50%之间和/或在1%至20%之间,和/或当对准时,可能没有干涉元件的弹性位移和/或者在药筒和输送装置之间没有弹力。
在一些实施例中,当将贮存部602完全插入座架604时,可在贮存部602和输送装置650之间产生连接和/或流体路径。例如,中空针636可刺穿贮存部602的隔膜638。可选地,穿刺隔膜638可以在装置650和贮存部602之间产生流体路径。例如,在图8A和图8B中示出是装置650的铰链841,铰链641和/或门640围绕铰链841旋转。
图9A-9C是根据本发明实施例的药筒稳定系统的照片。在一些实施例中,将药筒902插入药筒座架中。可选地,药筒902的前导面919接近干涉元件908。当药筒接近完全插入时,面919可选地接触干涉元件908,要么对准(药筒的与干涉元件908对准的干涉元件917),要么不对准。例如,当面919在未对准时(例如,如图9B所示)接触干涉元件908,药筒902可选地重新定向955,直到其与干涉元件908对准为止。例如,当药筒902对准时,药筒的前导面919上的干涉元件917可以与输送装置的干涉元件908互锁(例如,如图9C所示)。一旦干涉元件互锁,药筒902的定向可选地相对于输送装置锁定。在一些实施例中,当药筒902被锁定时,驱动器的进一步动作为药物输送提供动力。
图9A示出了根据本发明实施例的药筒902的接近干涉元件908的前导面919。可选地,药筒902的前导面919包括突出部分917和凹口918a、918b和918c。例如,在图9A中,突起917包括与干涉元件908互锁的互补干涉元件。在图9A的示例中,前导面919在不对准的情况下接近干涉元件908。例如,互补的干涉元件917未在药筒902的所示方向中对准以与干涉元件908互锁。
在一些实施例中,干涉元件908包括销。例如,在图9A-9C的实施例中,互补干涉元件包括突起917。可选地,突出的干涉元件可以是药筒和/或输送装置的一部分。可选地,输送装置的干涉元件可包括弹性部件。可选地或另外地,药筒上的干涉元件可包括弹性部件。可选地,药筒902包括连接器938。例如,连接器938可包括隔膜。例如,隔膜可以连接到输送装置的针638。可选地或另外地,药筒上的连接器可包括针。例如,针可以连接到输送装置的隔膜。
在一些实施例中,药筒的前导面在不对准的情况下到达输送装置的干涉元件908。可选地,驱动器使药筒902重新对准以与干涉元件908对准。例如,当完全插入药筒902时,突起917在移开的情况下与干涉元件908重叠和/或推动干涉元件908。例如,干涉元件908弹性地移位。推动干涉元件908可选地增加了对插入药筒的阻力。例如,干涉元件908的位移可以通过元件908的弹性弯曲(例如,如图9B所示)实现。可选地,干涉元件908的弹性位移允许完全插入药筒902,直到药筒纵向地固定在药筒座架中。
在一些实施例中,在将药筒902插入药筒座架中之后,启动驱动器。可选地,驱动器对药筒902重新定向。例如,药筒902旋转,如图9B中的箭头955所示。可选地,药筒的旋转继续,直到干涉元件908与凹口918b重叠为止。一旦干涉元件908与凹口918b重叠,干涉元件908就可选地卡入凹口918b中。例如,通过卡入凹口918b中,干涉元件908锁定药筒902的方向,例如如图9C所示。可选地,凹口918b的两个边缘可以处于急剧倾斜状态。例如,干涉元件的两侧可以是锐角的,例如以沿任一方向锁定。替代地或另外地,凹口918b的一侧可以是陡峭倾斜的(例如以防止在该方向上旋转)和/或另一侧可以是浅角度(例如以允许在该方向上旋转)。例如,沿优选方向的旋转需要在相反方向上旋转扭矩的100%至50%,和/或在沿相反(阻止)方向上旋转时的力的50%至20%之间和/或在20%至5%之间和/或在5%至1%之间和/或小于1%。
在一些实施例中,当干涉元件908与互补干涉元件917互锁时,药筒902被锁定并且其相对于输送装置是定向的,例如,如图9C中所示。例如,当干涉元件908与突起917重叠时,药筒902可以旋转,直到凹口918b与干涉元件908重叠,和/或干涉元件908对准以与互补干涉917锁定。例如,当凹口918b与干涉元件908重叠时,干涉元件908可选地卡入锁定药筒902的方向的凹口918b中。可选地或另外地,药筒902可以插入,其中干涉元件908和917已经处于锁定对准。例如,干涉元件908可以立即滑入凹口918a-918c中。当凹口918a-918c和908重叠并且药筒902完全插入时,干涉元件908可以不受应力。可替换地或另外地,当干涉元件908与凹口918a-918c重叠时,干涉元件908可以弹性地移位。例如,当两个干涉元件908和917对准以互锁时,这可以给出何时药筒完全插入的触觉符号。
