Description

试剂吸取方法、试剂供给装置及免疫分析仪 技术领域
本发明涉及体外诊断技术领域，特别是涉及一种试剂吸取方法、试剂供给装置及包含该试剂供给装置的免疫分析仪。
背景技术
全自动免疫分析仪能够对血液等待测样本中所含的抗体和抗原等目标分析物质进行定量或定性检测，通常将空置的反应器中加入待测样本和试剂(或称反应物)并经过混匀、孵育和清洗分离(Bound-free,结合分离，即BF分离，本文有时简称清洗)等步骤后，再在反应器中加入信号试剂以测量光信号或电信号，从而实现对待测样本中所含目标分析物的测量分析。
衡量免疫分析仪工作效率的一个重要参数为测试通量，测试通量可以理解为免疫分析仪在单位时间内可以报告测试结果的数量，即对含有目标分析物的反应器的测量个数，单位时间内所测量的反应器的总数量越多，免疫分析仪的测试通量越高。由于分析项目的反应模式和测试流程通常不同，免疫分析仪的测试通量不是一成不变的，通常将最大测试通量作为免疫分析仪测试快慢的衡量标准，本发明为了叙述方便，除非特别说明，测试通量特指分析仪的最大测试通量。将免疫分析仪对反应器的处理看成为流水线，如果单位时间内存在N个含有目标分析物的反应器完成测量而离开流水线，为保证测试按最大通量连续可靠的进行，则必须在相同时间内同样有N个空置的反应器进入流水线，即反应器在流水线进口处的流量(进口流量)与出口处的流量(出口流量)相等。同理，为确保整条流水线无缝、连续衔接，反应器在流水线中间各个环节的流量应与进口流量、出口流量相等，即流水线各处流量均相等。
对于传统的免疫分析仪，由于试剂吸取过程中占用时间较长，使得反应器在该吸取环节的流量较低，从而成为影响工作效率的瓶颈和短板，导致免疫分析仪难以满足较高测试通量的要求。
发明内容
根据本申请的各种实施例，提供一种能提高试剂吸取效率的试剂吸取方法。
一种试剂吸取方法，包括如下步骤：
提供试剂移液单元和至少两个用于存储试剂的存储单元，将试剂通过试剂容器存放在存储单元的多个存储部上；使每个存储单元存放相应分析项目所需的全部试剂组分；及
将存储部跟随存储单元运动，使试剂移液单元于抵达至吸液工位的存储部上的试剂容器中吸取试剂。
一种试剂供给装置，包括试剂移液单元和至少两个存储单元，所述存储单元上设置有用于存放试剂容器的多个存储部，所述试剂移液单元用于吸取所述存储部上的试剂容器中的试剂，其中，每个存储单元存放相应分析项目所需的全部试剂组分。
一种免疫分析仪，包括上述任一的试剂供给装置。

附图说明
为了更好地描述和说明这里公开的那些发明的实施例和/或示例，可以参考一幅或多幅附图。用于描述附图的附加细节或示例不应当被认为是对所公开的发明、目前描述的实施例和/或示例以及目前理解的这些发明的最佳模式中的任何一者的范围的限制。

具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
样本试剂(或称反应物)孵育特指反应器开始清洗(清洗分离)前，其内的反应物在恒温环境下发生的抗原抗体结合反应或生物素亲和素结合反应的过程。这里所述的试剂与分析项目为“一一对应”关系，即不同分析项目对应的具体试剂在配方、试剂量、组分数量等方面一般不同。根据具体分析项目的不同，试剂通常包括多个组分，如常见的2-5个组分，包括磁粒、酶标、稀释液、解离剂等试剂组分，例如T4试剂(thyroxine，甲状腺素)包含磁粒、酶标、解离剂三个组分。根据反应模式不同，一个分析项目的多个试剂组分可以一次性分配也可以分多个步骤分配，分步骤分配时按照分配次序定义为第一试剂、第二试剂、第三试剂等。孵育完成后进行清洗分离，清洗分离指用磁场捕捉结合后的磁粒、抗原和标记抗体的复合物，同时去除含游离(Free,游离)的标记抗体及其他未反应或结合成分(本文为表述方便，简称未结合成分)的过程。清洗分离后分配信号试剂，进行信号孵育(一般为1-6 分钟)，最后测量标记试剂与信号试剂反应产生的发光量(本文为表述方便，称为反应物信号)。信号试剂用于测量信号(通常为发光量)的产生，通常为通用试剂的一种，与分析项目为“一对多”的对应关系，即不同的分析项目共用信号试剂。信号孵育指清洗分离后的反应器在加入信号试剂后，在恒温环境下反应一段时间，使信号增强的过程。需要指出的是，由于信号试剂具体成分的不同，有些发光体系不需要信号孵育，在分配信号试剂过程中或分配完信号试剂后可以直接测量。信号试剂可以是一种或多种，如有些信号试剂包括第一信号试剂、第二信号试剂等。在免疫分析装置中，经过上述过程，定量或定性测定与标记试剂结合的样本中所含抗原或抗体。此外，免疫分析仪能够对样本进行与数种不同的分析项目相应的分析。
工作周期或循环，简称周期，是在测试过程中可循环重现的最短时间窗口，其通常具有固定的时间长度，在周期时间内，一定数量的过程操作、任务或工作包等，比如取液、混匀、孵育、清洗分离、测量等操作和任务，按照受控的顺序串行或并行执行。同一部件在一个周期内的任务通常串行执行，不同部件在同一个周期内的任务，取决于相关部件间的动作是否有依赖关系，可以串行执行或并行执行。在一个周期中执行的所有过程操作只有在需要时才执行，不一定会在另一个周期中重复。特别是，某些过程操作可以在每个周期中重复出现，而其它的可能会每两个或更多个周期发生一次。当多个测试连续进行时，由于每个测试通常处在测试进程的不同阶段，在单个周期内发生的所有的过程操作中，只有某些过程操作专用于执行一个测试，另外一些过程操作用于执行其它的测试，即在一个单个周期中，不同的过程操作分别专用于不同的试验。因此，测试通常在多个周期内完成，其中，用于进行测试的不同过程操作发生在不同的周期。为了提高测试效率和通量，对于存在速度瓶颈的部件，可以通过增加部件的数量和延长部件的周期来实现，这样不同部件的工作周期不一定相同，即同一系统中可能存在多个并行的周期，通常并行的多个周期的时间长度存在倍数关系，倍数通常等于同一部件的个数。当存在两个工作周期时，分别称为第一周期、第二周期，比如试剂移液单元数量为N个(N≧2,为自然数)时，每个试剂移液单元工作在第一周期，第一周期长度为第二周期的N倍，且N个试剂单元的动作序列连续“错开并行”第二周期。本发明可以实现高通量的免疫测试，典型的第二周期长度为4-15秒，对应的测试通量为每小时900-240个测试，即每小时可以连续报告900-240个结果。
同时参阅图1至图4，本发明一实施例提供的免疫分析仪10包括混匀装置100、反应装置200、试剂供给装置300、样本供给装置410和反应器供给装置420。反应器供给装置420用于提供洁净且空置的反应器20，样本供给装置410用于为空置的反应器20中加入样本，试剂供给装置300用于为盛放有样本的反应器20中再加入试剂，混匀装置100用于对盛放有样本和试剂的反应器20进行混匀处理，反应装置200用于对反应器20中混匀处理后的样本和试剂进行孵育、清洗和测量。
在一些实施例中，反应器供给装置420包括供给料仓、排序机构、供给滑道和供给盘。供给料仓用于存放洁净且空置的反应器20，供给料仓可以位于试剂供给装置300的后方，这样可以充分利用整机空间，使免疫分析仪10的结构变得更为紧凑，排序机构用于将散乱放置的反应器20进行整理以按一定秩序排列，供给滑道将排序后的反应器20逐个导入至供给盘，供给盘用于缓存供给滑道输送过来的反应器20，反应器20可以沿供给盘的周向间隔排列，供给盘可以绕自身的中心轴线转动，从而带动反应器20到指定位置，该指定位置可以定义为反应器供给工位，供给盘上的反应器20将于反应器供 给工位转移至混匀装置100。
在一些实施例中，样本供给装置410包括样本架、样本管、输送轨道和样本移液单元411等。样本架可以与输送轨道配合，样本管放置在样本架上，样本管用于盛放样本，例如，每个样本架上可以放置五个至十个左右的样本管。当样本架带动样本管沿输送轨道运动至指定位置时，样本移液单元411吸取样本管的样本，并将样本加入至空置的反应器20中。样本移液单元411可以采用钢针或一次性吸嘴，为了实现对样本的顺利吸取，样本移液单元411可以进行竖直上下运动、水平直线运动或水平转动等运动形式。
同时参阅图1和图2，在一些实施例中，混匀装置100为串联式，该串联式混匀装置101包括运输组件110和混匀组件120，运输组件110上至少设置两个混匀组件120，运输组件110能够带动所有混匀组件120朝同一方向同步运动，简而言之，所有混匀组件120串联在一个运输组件110上。
运输组件110包括机架111和设置于所述机架111上的传送器。传送器用于带动所有混匀组件120朝同一方向同步运动，可以由同步带、丝杠传动、齿轮齿条等传动形式或机构的一种或几种组成。
在一些实施例中，传送器包括电机113、主动轮114和从动轮115以及同步带112，电机113用于驱动主动轮114转动，同步带112缠绕在主动轮114和从动轮115上，当电机113转动时，主动轮114和从动轮115带动同步带112移动。
每个混匀组件120包括支座121、驱动器123和承载台122，支座121滑动设置在机架111上并与运输组件110的传送器连接。具体地，机架111上可以设置滑轨，支座121与滑轨配合，同步带112带动支架沿滑轨延伸的方向滑动，驱动器123安装在支座121上并与承载台122连接，承载台122用于放置反应器20，同步带112可以驱动每个混匀组件120上的支座121均朝同一方向运动，驱动器123能够带动承载台122产生偏心震荡，从而使反应器20中的反应物因产生非接触式偏心震荡而实现混匀。
承载台122上可以设置至少两个容置孔122a，反应器20插置在该容置孔122a中，从而实现承载台122对反应器20的承载作用。当然，容置孔122a还可以采用托架等实体结构进行替换，只要能将反应器20放置在承载台122上即可。
当混匀组件120的数量为两个时，其中一个混匀组件120包括第一支座1211和第一承载台1221，另外一个混匀组件120包括第二支座1212和第二承载台1222，第一支座1211具有第一安装端1211a，第二支座1212具有第二安装端1212a，第二安装端1212a靠近第一安装端1211a设置。第一承载台1221位于第一安装端1211a，第二承载台1222位于第二安装端1212a，简而言之，第一承载台1221和第二承载台1222相对设置，这样便于样本和试剂能够在指定位置加入至不同承载台122上的反应器20中。
参阅图5，当采用上述串联式混匀装置101对样本和试剂进行混匀时，可以形成串联式混匀方法，该串联式混匀方法主要包括如下步骤：
S510，提供用于承载反应器20的至少两个混匀组件120，采用同一运输组件110同步驱动混匀组件120在第一工位11和第二工位12之间循环往复运动；即同步带112驱动所有承载台122在第一工位11和第二工位12之间运动。
S520，向处于第一工位11处的反应器20中加入样本，向处于第二工位12处的反应器20中加入试剂，将反应器20中的样本和试剂进行混匀处理。当同步带112驱动承载台122运动到第一工位11 时，同步带112停止运动，由于样本移液单元411设置在第一工位11附近，样本移液单元411将吸取样本并加入至其中一个反应器20中；样本加入完毕后，同步带112驱动承载台122运动到第二工位12时，同步带112停止运动，可以通过试剂供给装置300中的试剂移液单元310将试剂加入至盛放有样本的反应器20中。当反应器20中加入有样本和试剂后，可以使驱动器123带动承载台122产生偏心震荡，以将反应器20中的样本和试剂通过非接触偏心震荡的方式进行混匀处理。
S530，将混匀组件120执行的动作序列或任务，包括移入反应器20、接受样本移液单元411加入样本、接受试剂移液单元310加入试剂、偏心震荡、移出已混匀完成的反应器20等动作，可循环重现的最短时间窗口记为第一周期，即混匀组件120连续两次执行同一动作的最小时间间隔为第一周期。用第一周期除以混匀组件120数量所得的值记为第二周期。从向其中一个混匀组件120第一次移入反应器20时起，依次错开一个第二周期所间隔的时间先后向其它每个混匀组件120中移入反应器20。可以理解，为了实现上述步骤，运输组件110的工作周期为第二周期，混匀组件120的工作周期为第一周期。运输组件110在每个第二周期内可同步驱动混匀组件120在第一工位11和第二工位12之间循环往复运动。
S540，将已混匀完成的反应器20依次错开一个第二周期所间隔的时间移出混匀组件120，在移出反应器20的混匀组件120上移入新的反应器20。
本发明可以实现高通量的免疫测试，第二周期的长度可以为4-15秒内任何合适的值，比如4秒、5秒、6秒、9秒等,对应的测试通量为每小时900-240个测试，即每小时可以连续报告900-240个结果。
以下为了叙述方便以10秒为例进行说明。
下面以运输组件110驱动两个混匀组件120同步运动为例进行说明，假如免疫分析仪10必须每隔10秒完成对一个反应器20的测量，即每隔10秒报告一个测试结果，此时，第二周期的时间为10秒。将整个免疫分析仪10看做流水线，必须保证流水线各处流量均相等，故混匀装置100上同样必须每隔10秒输出一个已混匀处理完毕的反应器20。假如在只有一个混匀组件120的情况下，由于混匀组件120在一个周期内执行的移入反应器20、接受样本移液单元411加入样本、接受试剂移液单元310加入试剂、偏心震荡混匀、移出已混匀完成的反应器20等动作序列所需要的时间总和大于10秒，混匀装置100将无法每隔10秒输出一个已混匀处理完毕的反应器20，混匀装置100的流量低于流水线的出口流量，导致流水线无法以最大效率连续工作。因此，通过将第一周期设置为第二周期的两倍，即第一周期为20秒，同时使得混匀组件120的数量为两个，使两个混匀组件120执行的动作序列相对错开第二周期的时间(即10秒)执行，即两个混匀组件120相隔一个第二周期而“错开并行”，在每个混匀组件120每隔20秒输出一个已混匀处理完毕的反应器20的基础上，整个混匀装置100将每隔10秒输出一个已混匀处理完毕的反应器20，最终达到“数量换时间”的目的。
当然，还可以设置初始工位13，使运输组件110带动混匀组件120在初始工位13、第一工位11和第二工位12之间循环往复运动；在初始工位13时，反应器20被移入或移出混匀组件120。初始工位13、第一工位11和第二工位12可以设置在同一直线上，并使初始工位13处于第一工位11和第二工位12之间，使得混匀组件120在初始工位13、第一工位11和第二工位12之间的运动轨迹为直线。初始工位13、第一工位11和第二工位12可以也可以设置在同一圆周上，使得混匀组件120在初始工 位13、第一工位11和第二工位12之间做圆周运动。与传统的混匀组件120在单个工位固定不动相比，运输组件110带动混匀组件120在多个工位之间循环往复运动，使混匀组件120在不同工位有条不紊地完成不同的动作序列，减少了样本移液单元411、试剂移液单元310等单元的运动行程，可以实现对反应器20更加灵活高效的任务操作，如接收反应器20、接收样本、试剂和混匀等任务，从而提高整机的测试通量。
具体而言，该串联式混匀装置101开始工作时，在初始工位13处向第一承载台1221上第一次加入一个反应器20，此时，第二承载台1222上并未加入反应器20；传送器驱动第一承载台1221和第二承载台1222从初始工位13运动至第一工位11，向第一承载台1221上的反应器20中加入样本；传送器驱动第一承载台1221和第二承载台1222从第一工位11运动至第二工位12，向第一承载台1221上盛放有样本的反应器20中加入试剂；第一承载台1221产生偏心震荡，使其反应器20中的样本和试剂开始混匀；传送器驱动第一承载台1221和第二承载台1222从第二工位12返回至初始工位13，此时，第一承载台1221和第二承载台1222于第10秒抵达初始工位13，向第二承载台1221上第一次加入反应器20；传送器驱动第一承载台1221和第二承载台1222从初始工位13运动再次至第一工位11，向第二承载台1222上的反应器20中加入样本；传送器驱动第一承载台1221和第二承载台1222从第一工位11运动再次至第二工位12，向第二承载台1222上盛放有样本的反应器20中加入试剂；第二承载台1222产生偏心震荡，使其反应器20中的样本和试剂开始混匀；传送器驱动第一承载台1221和第二承载台1222从第二工位12返回至初始工位13，此时，第一承载台1221和第二承载台1222于第20秒抵达初始工位13，在第一承载台1221上第二次加入反应器20，并向第一工位11运动。根据此混匀规律，当第一承载台1221和第二承载台1222于第20秒抵达初始工位13时，在第二承载台1222上第二次加入反应器20。依次类推，第一承载台1221和第二承载台1222于第20秒、第30秒、第10N秒(N≧2)抵达初始工位13时，均会有反应器20移入到混匀装置100。同样地，由于每个混匀组件120工作周期为第一周期(20秒)且混匀组件120之间的动作序列并行错开第二周期(10秒)，每个混匀组件120每隔20秒完成一个混匀处理的反应器20并从混匀装置100移出至反应装置200中，但整个混匀装置100每隔10秒会输出一个混匀处理完成的反应器20，使得混匀装置100的流量等于流水线的出口流量。事实上，当其中一个混匀组件120上的反应器20在混匀的同时，充分利用该混匀时间，在另一个混匀组件120上的反应器20加入样本或试剂，从而使整个混匀装置100的流量满足测试通量的要求。
当然，当第二周期仍然为10秒时，第一周期的时间还可以更长，此时使混匀组件120的数量为三个、四个甚至更多，第一周期可以设置为第二周期的三倍、四倍甚至更多，即第一周期为30秒或40秒等。这样在保证测试通量的基础上，可以减少运输组件110的运动速度，延长样本和试剂的混匀时间，有效解决运输组件110的运动速度瓶颈和样本、试剂的混匀时间瓶颈。在运输组件110的运动速度和样本、试剂的混匀时间一定的情况下，每个混匀组件120仍然每隔20秒输出一个混匀处理完成的反应器20，即第一周期仍然为20秒，如需提高免疫分析仪10的测试通量，例如要求每5秒的时间(第二周期)输出一个已测量完毕的反应器20，可以将运输组件110上的混匀组件120增加至四个；又如要求每4秒的时间(第二周期)输出一个已测量完毕的反应器20，可以将运输组件110上的混匀组件 120增加至五个。
可以在每个混匀组件120设置至少两个混匀位，混匀位即为承载台122上的容置孔122a，当其中一个混匀位(容置孔122a)被正在混匀或完成混匀的反应器20占用时，将反应器20移入该混匀组件120上的其它空闲混匀位(容置孔122a)。这样可以解决反应器20在同一承载台122上移入和移出过程中的混匀位占用问题，提高测试效率和测试通量。
对反应器20中的样本和试剂进行的混匀处理，可以在运输组件110驱动混匀组件120运动停止后进行，也可在运动过程中进行，例如，当混匀组件120从第二工位12返回至初始工位13的过程中，驱动器123使承载台122产生偏心震荡以混匀样本和试剂。在运动过程中进行混匀处理可以充分利用混匀组件120运动过程中的时间对样本和试剂进行混匀，确保混匀装置100满足测试通量要求。
加载有样本和试剂的反应器20从开始混匀到混匀完成所需的时间通常为2-10秒，运输组件110工作周期为第一周期，两个混匀组件120为第二周期，使得样本和试剂存在足够的时间进行混匀，确保样本和试剂能够产生充分反应，提高后续测量结果的精确性。
同时参阅图3和图4，在一些实施例中，混匀装置100为并联式，该并联式混匀装置102包括至少两个混匀机构103，每个混匀机构103包括运输组件110和混匀组件120，混匀组件120设置在运输组件110上，运输组件110驱动混匀组件120运动。例如每个混匀机构103包括一个运输组件110和一个混匀组件120时，各个混匀组件120之间行程相互并联关系。运输组件110和混匀组件120的结构与上述串联式混匀装置100中的对应结构相同，即每个运输组件110包括机架111和设置于机架111上的传送器，每个混匀组件120包括支座121、驱动器123和承载台122，在此不再赘述。其与串联式混匀装置100的主要不同点在于：混匀组件120分别设置在不同的运输组件110上，不同运输组件110上的混匀组件120的运动不同步。
在一些实施例中，至少一个混匀机构103包括一个运输组件110和至少两个混匀组件120，该运输组件110驱动上述至少两个混匀组件120同步运动，此时，该混匀机构103上的至少两个混匀组件120相互串联，该混匀机构103上的混匀组件120与其它混匀机构103上的混匀组件120相互并联，即整个混匀装置100中的混匀组件120同时存在并联和串联(即混联)关系。
参阅图6，当采用上述并联式混匀装置102对样本和试剂进行混匀时，可以形成并联式混匀方法，该并联式混匀方法主要包括如下步骤：
S610，提供至少两个运输组件110，使每个运输组件110上设置有用于承载反应器20的混匀组件120，各运输组件110驱动混匀组件120在第一工位11和第二工位12之间循环往复运动。
S620，向处于第一工位11处的反应器20中加入样本，向处于第二工位12处的反应器20中加入试剂，将反应器20中的样本和试剂进行混匀处理。
S630，将混匀组件120执行的动作序列或任务，包括移入反应器20、接受样本移液单元411加入样本、接受试剂移液单元310加入试剂、偏心震荡、移出已混匀完成的反应器20等动作，可循环重现的最短时间窗口记为第一周期，即混匀组件120连续两次执行同一动作的最小时间间隔为第一周期。用第一周期除以混匀组件120数量所得的值记为第二周期。从向其中一个运输组件110上的混匀组件120第一次移入反应器20时起，依次错开一个第二周期所间隔的时间先后向其它运输组件110上的混 匀组件120上移入反应器20。可以理解，为了实现上述步骤，每个运输组件110和混匀组件120的工作周期都为第二周期。
S640，将已混匀完成的反应器20依次错开一个第二周期所间隔的时间移出混匀组件120，在移出反应器20的混匀组件120上放入新的反应器20。
下面以运输组件110的数量为两个，其每个运输组件110上设置一个混匀组件120为例进行说明，与串联式混匀方法的相同之处请参照上面的描述。假定第二周期为10秒，而每个混匀机构103每隔20秒输出一个已混匀完毕的反应器20，即第一周期为20秒，由于依次错开一个第二周期所间隔的时间(10秒)先后向其它运输组件110上的混匀组件120上移入反应器20，最终使得整个混匀装置100将每隔10秒输出一个已混匀处理完毕的反应器20，同样能够起到“数量换时间”的作用。
参照上述对于串联式混匀方法的描述，在并联式混匀方法中，同样可以设置初始工位13，使运输组件110带动混匀组件120在初始工位13、第一工位11和第二工位12之间循环往复运动；在初始工位13时，反应器20被移入或移出混匀组件120。初始工位13、第一工位11和第二工位12可以设置在同一直线上，并使初始工位13处于第一工位11和第二工位12之间，使得混匀组件120在初始工位13、第一工位11和第二工位12之间的运动轨迹为直线。
与传统的混匀组件120在单个工位固定不动相比，运输组件110带动混匀组件120在多个工位之间循环往复运动，提高了整机的测试通量。
每个混匀组件120设置至少两个混匀位，混匀位即为承载台122上的容置孔122a，两个混匀位同时使用或交替使用，可以提高混匀组件120对反应器20的处理效率。当其中一个混匀位(容置孔122a)被占用时，可将反应器20移入该混匀组件120上的另外一个混匀位(容置孔122a)上。可在运输组件110驱动混匀组件120运动的过程中或运动停止后，对反应器20中的样本和试剂进行混匀处理，即对反应器20中的样本和试剂的混匀不受运输组件110运动状态的限制，这样可以使混匀装置100更灵活高效。
具体而言，该并联式混匀装置100开始工作时，将其中一个运输组件110记为第一运输组件1101，另外一个运输组件110记为第二运输组件1102。在初始工位13处向第一运输组件1101上的承载台122第一次加入一个反应器20，此时第二运输组件1102上的承载台122并未加入反应器20。
对于第一运输组件1101，当其从初始工位13运动到第一工位11时，向第一运输组件1101的承载台122上的反应器20加入样本；第一运输组件1101从第一工位11运动至第二工位12，向第一运输组件1101的承载台122上盛放样本的反应器20中加入试剂；第一运输组件1101的承载台122产生偏心震荡，使其反应器20中的样本和试剂开始混匀。
对于第二运输组件1102，在第一次向第一运输组件1101上的承载台122加入反应器20后的第10秒，向第二运输组件1102上的承载台122第一次加入反应器20，并使第二运输组件1102根据第一运输组件1101的运动规律开始运动。依次类推，第一运输组件1102上的承载台122和第二运输组件1102上的承载台122于第20秒、第30秒、第10n秒抵达初始工位13时，均会有反应器20移入到混匀装置100。同样地，由于每个混匀组件120工作周期为第一周期(20秒)且混匀组件120之间的动作序列并行错开第二周期(10秒)，每个混匀组件120每隔20秒完成一个混匀处理的反应器20并从混匀装 置100移出至反应装置200中，但整个混匀装置100每隔10秒会输出一个混匀处理完成的反应器20。
对于并联式混匀方法，将运输组件110带动混匀组件120相隔一个第二周期(10秒)而“错开并行”，尽管每个混匀机构103相隔20秒(第一周期)输出一个已混匀完毕的反应器20，但是两个混匀机构103错开10秒从初始工位13开始运行，从而使得整个混匀装置100每隔10秒(第二周期)输出一个已混匀处理完毕的反应器20。通过增加混匀机构103的数量，在使整个混匀装置100的流量满足测试通量要求的基础上，运输组件110能够以较慢的速度运动，解决了运输组件110的运动速度瓶颈和样本、试剂之间的混匀时间瓶颈。其它相似之处请参照上述串联式混匀方法的相关描述。
当至少一个运输组件110上设置的混匀组件120的数量不少于两个时，使得该运输组件110驱动设置在其上的所有混匀组件120同步运动，即至少一个混匀机构103包括至少两个混匀组件120，该混匀机构103上的混匀组件120为串联关系，因此，整个混匀装置100上的混匀组件120同时存在并联与串联关系，同样地，使得每个混匀组件120相隔一个第二周期的时间第一次加入反应器20，最终使整个混匀装置100相隔一个第二周期的时间输出一个已混匀处理完毕的反应器20。通过将部分混匀组件120串联设置，可以使得整个混匀装置100的结构更为紧凑。
同时参阅图1和图3，在一些实施例中，试剂供给装置300靠近第二工位12设置，试剂供给装置300包括试剂移液单元310和存储单元320，存储单元320的数量至少为两个，存储单元320上设置多个存储部321，存储部321用于放置和存储试剂容器，试剂则盛放在试剂容器中，试剂移液单元310用于吸取存储部321上的试剂容器内的试剂组分，并将试剂组分加入至处于第二工位12处的反应器20中。存储部321的数量可以根据需要而设置，考虑到使用需求、成本和布局，每个存储单元320上的存储部321的数量最好为15-50个，比如每个存储单元320上的存储部321的数量都为25个，这样两个存储单元320一共可以同时在线存储50个试剂容器。每个存储单元320存放相应分析项目所需的全部试剂组分，例如，在一个分析项目中，必须向反应器20中加入磁粒、酶标和解离剂共三个试剂组分，则将磁粒、酶标和解离剂三个组分盛放在同一个存储单元320上。当某个分析项目需要装载多个试剂容器以扩充该项目的上机测试量时，多个试剂容器可以按任何合适的组合存放于每个存储单元。比如存储单元数量为2个时，需要装载3个每个含100个测试的TSH(thyroid stimulating hormone，促甲状腺激素)试剂容器，可以将3个TSH试剂容器都装载在同一个存储单元，也可以1个TSH试剂容器装载在其中一个存储单元、另外2个装载在另一个存储单元。
对于传统的试剂供给装置300，为增加分析项目的存储量，必须增加存储部321的数量，从而导致整个存储单元320的尺寸增大，存储单元320占用面积较大，不利于存储单元320的布局和生产制造，另一方面，对于体积和重量较大的存储单元320，也增加了对其运动控制的难度，导致存储部321无法在很短的时间内抵达指定位置以供试剂移液单元310吸取试剂，成为实现高测试通量的一个瓶颈。此外，传统的试剂供给装置300将用于同一分析项目的多个试剂组分盛放在不同的存储单元320上，不仅使得试剂移液单元310在多个不同的存储单元320上吸取同一分析项目的试剂，导致试剂移液单元310行程较大和运动逻辑复杂，无法实现高测试通量，还要求试剂组分盛放在多个试剂容器中，导致生产制造成本高、用户操作不便等问题，此外，由于同一分析项目的多个试剂组分盛放在不同的存储单元320上，当某个存储单元故障不工作时，还会直接导致仪器无法继续测试。
上述实施例的试剂供给装置300通过设置至少两个存储单元320，每个存储单元320体积较小，有利于整机布局和运动控制，也能确保整个试剂供给装置300有较大的试剂存储量。同时，每个存储单元320存放相应分析项目所需的全部试剂组分，可以提高试剂供给装置300的可靠性和对故障的容忍度，当其中一个存储单元320出现故障而无法工作时，其它剩余存储单元320可以继续工作，确保试剂供给装置300仍能有效工作。当然，可以在其它存储单元320工作的同时，对出现故障的存储单元320进行整修。
存储单元320可以为转动盘，转动盘进行周期性间歇转动，从而带动存储部321到指定位置(即吸液工位14)，以便试剂移液单元310在吸液工位14吸取存储部321上的试剂。试剂移液单元310可以与转动盘的数量相等，每个转动盘分别对应一个试剂移液单元310，每个试剂移液单元310从与其对应的转动盘中吸取试剂。与样本移液单元411相类似，试剂移液单元310可以采用钢针或一次性吸嘴，为了实现对试剂的顺利吸取，试剂移液单元310可以进行竖直上下运动、水平直线运动或水平转动等运动形式。当然，试剂移液单元310的数量也可以为一个，该一个试剂移液单元310在多个转动盘中吸取试剂。
试剂供给装置300还包括扫描器，扫描器设置在存储单元320上，扫描器可以识别存储部321上试剂容器的条码信息，从而用以区分不同的试剂。为使整个试剂供给装置300结构紧凑，扫描器采用固定式设置。存储单元320上还可以设置制冷器，制冷器可以对存储部321中的试剂进行冷藏处理，从而实现在线长期保存试剂。
参阅图7，为了实现高通量的免疫测试，当采用上述试剂供给装置300对试剂进行吸取时，可以形成对试剂的吸取方法，该吸取方法主要包括如下步骤：
S710，提供试剂移液单元310和至少两个用于存储试剂的存储单元320，将试剂容器存放在存储单元320的多个存储部321上，使每个存储单元320存放相应分析项目所需的全部试剂组分。
S720，将存储部321跟随存储单元320运动，使试剂移液单元310从抵达至吸液工位14的存储部321中吸取试剂。存储单元320的运动可以为转动，例如存储单元320做周期性间歇转动，从而使吸液工位14处每隔设定时间均有存储部321抵达，以便试剂移液单元310吸取试剂。
S730，将每个存储单元320执行的动作序列可循环重现的最短时间窗口记为第一周期，即存储单元320连续两次执行同一动作的最小时间间隔为第一周期。用第一周期除以存储单元320的数量所得的值记为第二周期。从其中一个存储单元320第一次带动存储部321朝吸液工位14运动时起，依次错开一个第二周期所间隔的时间先后使其它存储单元320带动存储部321朝相应的吸液工位14运动。
以两个存储单元320为例进行说明，根据流量处处相等的原理，该第二周期的值与上述混匀方法中所提到的第二周期的值是相等的，同样以10秒为例进行说明，即每个10秒有一个存储部321抵达吸液工位14以供试剂移液单元310吸取试剂。当然，该第一周期的值与上述混匀方法中所提到的第一周期的值同样是相等的，即第一周期的值为20秒。参照上述混匀方法的基本原理，将两个存储单元320相隔一个第二周期而“错开并行”，尽管每个存储单元320每相隔20秒将有一个存储部321抵达相应的吸液工位14，但是两个存储单元320的动作序列先后错开10秒开始执行，从而使得整个试剂供给装置300每个10秒将有一个存储部321抵达吸液工位14供试剂移液单元310吸取试剂，通过增加存储 单元320的数量以换取时间，在使整个试剂供给装置300的流量满足测试通量要求的基础上，可以使存储单元320以较慢的速度转动，继而解决了存储单元的运动速度瓶颈。当然，当存储单元320的数量越多时，在存储单元320转动速度不变的情况下，可以增大整个试剂供给装置300的流量，进而提高免疫分析仪10的测试通量。
在一些实施例中，如果适当降低免疫分析仪测试通量或者采用其它高成本设计提高存储单元的运动速度，存储单元320的运动速度不成为免疫分析仪测试通量的瓶颈时，多个存储单元320的动作序列可以“同步串行”，即多个存储单元320在工作周期内的动作序列同步，在工作周期间串行，在每个工作周期内每个存储单元320都可将目标存储部321定位至吸液工位14以供试剂移液单元310吸取试剂，但每个工作周期只需一个存储单元320将目标存储部321定位至吸液工位14以供试剂移液单元310吸取试剂。以两个存储单元320(分别记为第一存储单元、第二存储单元)、工作周期10秒为例进行说明。在第1个10秒,第一存储单元的一个存储部321抵达吸液工位14以供试剂移液单元310吸取试剂；第2个10秒,第二存储单元的一个存储部321抵达吸液工位14以供试剂移液单元310吸取试剂；第3个10秒,第一存储单元的一个存储部321抵达吸液工位14以供试剂移液单元310吸取试剂；按此规律，每个10秒两个存储单元320在周期间交替串行,将一个存储部321抵达吸液工位14以供试剂移液单元310吸取试剂。当然，也可以在第1、第2、…第N个10秒(N≧1),第一存储单元将存储部321定位至吸液工位14以供试剂移液单元310吸取试剂；第N、(N+1)、…第(N+M)个10秒(M≧1),第二存储单元将存储部321定位至吸液工位14以供试剂移液单元310吸取试剂。总之，任一个工作周期，都可由其中的一个存储单元将存储部321定位至吸液工位14以供试剂移液单元310吸取试剂。
对于同一存储单元320，存放一个测试对应分析项目所需的全部试剂组分，便于试剂移液单元310快速吸取试剂，提高试剂供给装置300供给试剂的流量。另一方面，当该存储单元320出现故障时，仪器可以利用其它存储单元320继续测试，不影响仪器测试的正常进行，提高了对故障的容忍度。此外，一个测试对应分析项目所需的全部试剂组分放在同一个存储单元320，可以用一个含有多个试剂腔的试剂容器盛放，不仅节约了生产制造成本，还方便用户装卸等操作。
在存储部321跟随存储单元320转动(公转)的过程中，使存储部321上的试剂容器的至少一个腔(如盛放磁粒试剂组分的磁粒腔)绕其自身的中心轴线产生自转，使得以固体悬浮液形式存在的磁粒试剂组分产生涡旋，避免其中的固体物质(例如磁粒)产生沉淀。
多个存储单元320为独立设置，即每个存储单元320可以独立旋转将存储部321上的试剂定位至吸液工位14。需要指出的是，此处的“独立设置”与存储单元320之间的空间布局和物理位置无关，比如多个存储单元320可以分开不重叠的分布在仪器上，也可以其中一个存储单元320嵌套在另一个存储单元320的外围或内侧。当然为了更好的布局和控制，多个存储单元320最好为相同构造且分开布局。多个存储单元320独立设置，可以提高控制的灵活性，进一步提高试剂供给的效率，从而提高仪器的处理通量。
可以使试剂移液单元310与存储单元320的数量相等，且每个存储单元320分别对应一个试剂移液单元310，即每个存储单元320均由与其对应的试剂移液单元310吸取试剂。显然，试剂移液单元310的数量增多时，在满足测试通量的基础上，可以减低每个试剂移液单元310的运行速度，解决试剂 移液单元310的运动速度瓶颈。
同时参阅图1和图3，在一些实施例中，反应装置200包括旋转盘210、转移组件220、测量器230、清洗组件250。旋转盘210上设置有孵育圈203、清洗圈202和测量圈201，孵育圈203、清洗圈202和测量圈201均环绕旋转盘210的旋转中心设置，孵育圈203上设置有孵育位213，孵育位213沿孵育圈203的周向间隔设置；清洗圈202上设置有清洗位212，清洗位212沿清洗圈202的周向间隔设置；测量圈201上设置有测量位211，测量位211沿测量圈201的周向间隔设置。孵育位213、清洗位212和测量位211均用于放置反应器20，三者可以为槽孔或托架等合适承载反应器20的结构。测量器230与旋转盘210连接，测量器230能够对加入信号试剂后的反应器20进行光信号的测量，以实现对反应物的进一步分析。清洗组件250位于清洗圈202的上方，包括注液部和吸液部，注液部对清洗位212上的反应器20进行注清洗缓冲液、吸液部可以下降和上升进出清洗位212上的反应器20内抽取移除反应器20内的未结合成分。进一步地，为了精简结构，清洗组件250还包括注信号试剂部，用于向清洗位212上的清洗分离后的反应器20内注入信号试剂。在一些实施例中，反应装置200还包括吸废液组件240和信号试剂混匀单元430。吸废液组件240位于测量圈201的上方，反应器20测量完毕后，吸废液组件240可以下降和上升进出测量位211上的反应器20中，将反应器20内的废液(主要为信号试剂)吸除，最后将吸除废液后的反应器20移送至丢弃站，以实现固体垃圾和液体垃圾的分置处理，减少生物危害风险。进一步地，吸废液组件240可以连接在清洗组件250的吸液部上，与清洗组件250的吸液部一起可以下降到反应器内底部吸取液体，吸完后再抬离反应器。这样可以充分利用清洗组件250的功能，缩减了机构体积和节省了成本，避免了独立设置吸废液组件而导致的结构复杂、成本高等问题。信号试剂混匀单元430独立于旋转盘210设置，包括与前述混匀组件120类似或相同的混匀组件，对含有信号试剂的反应器20进行偏心震荡混匀。
转移组件220将已混匀处理完毕的反应器20从混匀装置100上移出并移入至孵育位213，反应器20在跟随旋转盘210转动的过程中，孵育位213对反应器20中经混匀处理后的样本和试剂孵育设定时间。反应器20孵育完毕后，转移组件220将反应器20从孵育位213转移至清洗位212，反应器20在跟随旋转盘210转动的过程中，清洗组件250的注液部可以向处于清洗位212中的反应器20中先注入清洗液，然后通过磁场将磁粒复合物吸附在反应器20内侧壁上，清洗组件250的吸液部再从反应器20中抽取未结合成分，经过多轮“注入清洗液—吸附—抽取未结合成分”后，反应器20的反应物完成清洗分离。反应器20的反应物清洗分离完成后，注信号试剂部可以向反应器20中加入信号试剂，转移组件220将加入信号试剂的反应器20从清洗位212转移至信号试剂混匀单元430，通过信号试剂混匀单元430对其进行混匀。为了使信号试剂充分混匀又不影响仪器的测试通量，信号试剂混匀时长为2-6秒。含有信号试剂的反应器20混匀完成后，转移组件220将反应器20从信号试剂混匀单元430转移至测量位211，若需要对盛有信号试剂的反应器20继续进行信号孵育，可以在反应器20跟随旋转盘210转动的过程中，测量位211对反应器20进行孵育设定时间，当反应器20跟随旋转盘210前进到测量器230所在位置时，测量器230对反应器20中的反应物信号测量以便对反应物进行分析。
孵育圈203、清洗圈202和测量圈201三者同心设置，即三者均以旋转盘210的旋转中心为圆心。孵育圈203、清洗圈202和测量圈201环绕旋转中心由内向外依次间隔设置，即测量圈201靠近旋转盘 210的边缘，孵育圈203靠近旋转盘210的中心，清洗圈202设置在孵育圈203和测量圈201之间。为了满足分析项目孵育时间的要求，在保证孵育位213的数量的同时又不导致反应装置200的旋转盘210的尺寸过大，孵育圈203的数量至少为两个，例如可以为2-10个，其中最靠近旋转中心的孵育圈203记为内孵育圈，最远离旋转中心的孵育圈203记为外孵育圈。根据清洗效率的需要，清洗圈202的数量设置为1-2个。测量圈201的数量为1个，可以满足测量的需要。
反应装置200设置有孵育进出工位15、清洗移入工位16、清洗移出工位17和测量进出工位18。为了反应器可以进出反应装置200的各个孵育圈203、清洗圈202和测量圈201，孵育进出工位15的数量不少于孵育圈203的数量，清洗移入工位16和清洗移出工位17的数量分别与清洗圈202的数量相等，测量进出工位18的数量不少于测量圈201的数量，即至少为一个。进一步地，为了整机布局的紧凑，同时减少转移组件220的运动行程和提高其可靠性，并进一步提升工作效率，清洗移入工位16和清洗移出工位17分别设置在旋转盘210的旋转中心的两侧，即位于清洗圈202直径的两端，孵育进出工位15与清洗移入工位16同侧，测量进出工位18与清洗移出工位17同侧。这样从孵育进出工位15移出的反应器可以就近从清洗移入工位16移入到清洗圈202，从清洗移出工位17移出的反应器可以就近从测量进出工位18移入测量圈201。
具体地，以一步法反应模式的测试为例，转移组件220将混匀装置100上的反应器20从孵育进出工位15移入至孵育位213，当反应器20跟随旋转盘210运动至孵育进出工位15时，转移组件220将反应器20从孵育进出工位15移出孵育位213、并从清洗移入工位16移入至清洗位212；当反应器20跟随旋转盘210运动到清洗移出工位17时，转移组件220将反应器20从清洗移出工位17移出清洗位212并移入信号试剂混匀单元430进行信号试剂混匀，混匀完成后再从测量进出工位18移入测量位211；反应器20跟随旋转盘210运动至测量器230所在位置时，测量器230对反应信号测量完毕后，反应器20继续跟随旋转盘210运动至吸废液组件240所在位置，吸废液组件240将反应器20中的废液全部吸除，吸除废液后的反应器20继续跟随旋转盘210运动至测量进出工位18，此时，转移组件220在测量进出工位18将测量完成并吸废液后的反应器20移出测量位211、并将其移入丢弃站。当进行其他反应模式的测试时，比如延时一步法或两步法测试，转移组件220可将从孵育进出工位15移出孵育位213的反应器20、将从清洗移出工位17移出清洗位212的反应器20移入到混匀装置100中。
转移组件220在初始工位13、孵育进出工位15、清洗移入工位16、清洗移出工位17和测量进出工位18之间的运动轨迹为直线，该直线在旋转盘210的正投影通过旋转盘210的旋转中心。这样可以使转移组件220的运动简单化，提高转移组件220的工作效率，以满足测试通量的要求。转移组件220的运动轨迹所在的直线还经过信号试剂混匀单元430，转移组件220可将反应器20在信号试剂混匀单元430和测量圈201、清洗圈202之间转移。
为减少单个转移组件220的运动行程，进一步提高工作效率和控制精度，转移组件220的数量可以设置为两个，并在旋转盘210的内孵育圈内(最靠近旋转中心)设置中继站214，中继站214用于暂时承载反应器20。其中一个转移组件220的运动轨迹在旋转盘210形成第一投影，另外一个转移组件220的运动轨迹在旋转盘210形成第二投影，第一投影和第二投影在中继站214处连接成同一直线，记为轨迹直线；以通过中继站214并垂直于该轨迹直线的直线做为参考直线。其中一个转移组件220负 责反应器20位于参考直线右侧部分的转移，另外一个转移组件220负责反应器20位于参考直线左侧部分的转移。比如，两步法反应模式测试时，转移组件220将反应器20从清洗移出工位17移出清洗位212、并移入到混匀组件120加注第二试剂时，需要将反应器20从参考直线的左侧部分转移至右侧部分，可以通过一个转移组件220将反应器20从参考直线的左侧部分的清洗位212先转移至中继站，然后通过另外一个转移组件220将该反应器20从中继站再转移至参考直线的右侧部分的混匀组件120中。
在一些实施例中，为了布局紧凑和进一步提高转移组件220之间的协调配合效率，从而提高仪器通量，中继站214设置于旋转盘210的旋转中心。
同时参阅图1和图3，在该免疫分析仪10中，可以将其中的运输组件110、混匀组件120、样本移液单元411和试剂移液单元310四者组合形成一个稀释装置，即该稀释装置包括运输组件110、混匀组件120和移液组件，该移液组件包括样本移液单元411和试剂移液单元310，当然，运输组件110、混匀组件120、样本移液单元411和试剂移液单元310的结构和位置均可以保持不变。和上述混匀装置100类似，稀释装置同样可以设置初始工位13、第一工位11和第二工位12，当然，初始工位13也可以省略。
混匀组件120设置在运输组件110上，混匀组件120能够同时承载至少两个反应器20，以同时承载两个反应器20为例，其中一个反应器20记为第一反应器，另外一个反应器20记为第二反应器。混匀组件120上设置至少两个容置孔122a，第一反应器和第二反应器能够分别放置在不同的容置孔122a中。运输组件110驱动混匀组件120在初始工位13、第一工位11和第二工位12之间运动。
在稀释装置的工作过程中，当混匀组件120在初始工位13时，通过转移组件220从供给盘上将第一反应器转移至混匀组件120中；当混匀组件120运动到第一工位11时，通过样本移液单元411吸取样本加入至第一反应器中；当混匀组件120运动到第二工位12时，通过试剂移液单元310吸取稀释液加入至第一反应器中，并对样本和稀释液混匀以形成稀释样本；当混匀组件120再次返回初始工位13时，通过转移组件220向混匀组件120上移入第二反应器；当混匀组件120再次运动到第一工位11时，通过样本移液单元411将稀释样本的一部分从第一反应器中转移至第二反应器，当混匀组件120再次运动到第二工位12时，通过试剂移液单元310吸取试剂组分加入至盛放有稀释样本的第二反应器中，并将稀释样本和试剂组分混匀处理；当混匀组件120最后运动到初始工位13时，通过转移组件220将第二反应器移入反应装置200的孵育位213中。当然，可以将第一反应器移动至丢弃站丢掉。根据上述操作规律，可以通过稀释装置持续不断输出稀释样本和试剂组分已混匀处理的反应器20，实现样本的自动稀释。
进一步地，为了更大提高样本自动稀释的效率，混匀组件120的数量至少为两个，每个混匀组件120都可实现样本的自动稀释，混匀组件120之间可并行或串行实现样本的自动稀释。与前述的串联式混匀装置类似，同一运输组件110同步驱动混匀组件120在第一工位11和第二工位12之间循环往复运动；与前述的并联式混匀装置类似，设置至少两个运输组件110，每个运输组件110上设置有用于承载反应器20的混匀组件120，各运输组件110驱动混匀组件120在第一工位11和第二工位12之间循环往复运动。
参阅图8，当采用上述稀释装置实现样本自动稀释、并对稀释样本和试剂组分进行混匀时，可以形成稀释方法，该稀释方法主要包括如下步骤：
S810，将混匀组件120承载第一反应器运动到第一工位11，向第一反应器20中加入样本；
S820，将盛放有样本的第一反应器运动到第二工位12，向第一反应器中加入稀释液；
S830，将第一反应器中的样本和稀释液混匀以形成稀释样本；
S840，向混匀组件120上再移入一个第二反应器并再次运动到第一工位11，将第一反应器20中的稀释样本的一部分加入第二反应器中；
S850，将混匀组件120运动到第二工位12，向第二反应器中加入试剂组分；及
S860，将第二反应器中的稀释样本和试剂组分混匀，稀释样本和试剂组分混匀完成后，将第二反应器转移至反应装置200的孵育位213中。
当混匀组件120的数量至少为两个时，每个混匀组件120可在上述稀释步骤中轮流使用。以两个混匀组件120为例，第一样本自动稀释时使用第一混匀组件，第二样本稀释时使用第二混匀组件，第三样本自动稀释时使用第一混匀组件…
为提高工作效率，将稀释液和试剂组分两者均放置在同一存储单元320上。当稀释样本的一部分加入至第二反应器后，将第一反应器移出混匀组件120并丢弃至丢弃站中，当然，为实现固液分离，可以先将第一反应器中剩余的稀释样本吸取，再将稀释样本全部吸取完成后所形成的第一反应器丢弃。
为便于反应器20移入或移除混匀组件120，将混匀组件120在初始工位13、第一工位11和第二工位12之间循环往复运动，在初始工位13时，第一、第二反应器20被移入或移出混匀组件120。类似地，将初始工位13、第一工位11和第二工位12设置在同一直线上，使初始工位13处于第一工位11和第二工位12之间。对于第一反应器20中的样本和稀释液、以及第二反应器20中的稀释样本和试剂，混匀组件120通过非接触偏心震荡的方式对其混匀。
可以看出，本发明的稀释装置集成了混匀组件120，可在不同工位之间运动，完成样本的自动稀释和混匀，避免了移液单元在一个固定工位稀释，再将反应器转移到另一个工位混匀，提高了稀释混匀的效率和效果，解决了样本自动稀释限制免疫测试的高通量瓶颈问题。
参阅图9，采用上述免疫分析仪10，可以形成一种免疫分析方法，以免疫分析的一步法反应模式为例，该免疫分析方法主要包括如下步骤：
S910，提供用于承载反应器20的至少两个混匀组件120，使混匀组件120带动反应器20在第一工位11和第二工位12之间往复运动。
S920，将混匀组件120执行的动作序列或任务可循环重现的最短时间窗口记为第一周期，即混匀组件120连续两次执行同一动作的最小时间间隔为第一周期，用第一周期除以混匀组件120数量所得的值记为第二周期。从向其中一个混匀组件120第一次移入反应器20时起，依次错开一个第二周期所间隔的时间先后向其它每个混匀组件120中移入反应器20。
S930，将已混匀完成的反应器20依次错开一个第二周期所间隔的时间移出混匀组件120，在移出反应器20的混匀组件120上移入新的反应器20。
S940，将移出混匀组件120并盛放有反应物的反应器20依次进行孵育、清洗分离和测量。反应器 20的孵育时间在5-60分钟。
可以理解，该第二周期等于从反应装置200上连续输出相邻两个已测量完毕的反应器20所间隔的时间，即免疫分析仪10连续报告两个相邻测试结果所间隔的时间。
当进行其他方法的反应模式测试时，比如延时一步法和两步法测试，在上述步骤S940中，可将孵育后或清洗后的反应器20按照S920、S930的步骤再次移入到混匀装置100中加入第二试剂和混匀，混匀完成后再按步骤S940进行孵育、清洗分离和测量。
具体地，步骤S940的孵育还可包括如下第一孵育和第二孵育：
第一孵育，含有样本和第一试剂的反应器20孵育设定时间。
第二孵育，将经过第一孵育后的反应器20中再加入第二试剂后孵育设定时间。
当孵育包括第一孵育和第二孵育时，在清洗步骤之前，将经过第一孵育的反应器20按照S920、S930的步骤再次移入到混匀装置100中加入第二试剂和混匀，混匀完成后再按步骤S940进行第二孵育、清洗分离和测量。
试剂分两次加入反应器20中，每次加入试剂组分后对通过混匀装置100对反应器20进行混匀。在一些实施例中，该免疫分析方法还包括如下步骤：
将经过第一孵育后的反应器20进行第一清洗；
将经过第一清洗处理后的反应器20进行第二孵育；
将经过第二孵育的反应器20进行第二清洗。
具体地，当反应器20经过S910、S920、S930步骤后，首先通过反应装置200将反应器20进行第一孵育，接着将第一孵育后的反应器20通过反应装置200进行第一次清洗，第一次清洗后将反应器20按照S920、S930的步骤再次移入到混匀装置100中加入第二试剂和混匀，混匀完成后再按步骤S940进行孵育、第二次清洗和测量。
在一些实施例中，例如，将同一运输组件110驱动所有混匀组件120同步运动，即采用上述串联式的混匀方法对反应器20中的样本和试剂混匀。又如，使运输组件110的数量为多个，且每个运输组件110至少驱动一个混匀组件120运动，即采用上述并联式的混匀方法对反应器20中的样本和试剂混匀。
参考上述串联式和并联式的混匀方法，可以使运输组件110带动混匀组件120在初始工位13、第一工位11和第二工位12之间循环往复运动；在初始工位13时，将反应器20被移入或移出混匀组件120，向处于第一工位11处的反应器20中加入样本，向处于第二工位12处的反应器20中加入试剂。
参考上述反应装置200的结构和工作原理，可以将反应器20从孵育进出工位15进入旋转盘210上的孵育位213进行孵育，将反应器20从清洗移入工位16进入旋转盘210上的清洗位212进行清洗分离，将反应器20从清洗移出工位17将清洗分离完成后的反应器20移出清洗位212，将反应器20从测量进出工位18移入旋转盘210上的测量位211进行测量；使转移组件220在孵育进出工位15、清洗移入工位16、清洗移出工位17和测量进出工位18之间的运动轨迹处于同一直线上。
在旋转盘210的内孵育圈内(最靠近旋转中心)设置中继站214，特别地，在旋转中心处设置有用于暂时承载反应器20的中继站214，并使转移组件220的数量设置为两个，其中一个转移组件220的 运动轨迹在所述旋转盘210形成第一投影，另外一个转移组件220的运动轨迹在所述旋转盘210形成第二投影，使第一投影和第二投影在中继站214处连接成同一直线。将孵育位213、清洗分离和测量位211设置在同一旋转盘210上。
当测量完成后，先将反应器20中的废液吸除，再将吸除废液后的反应器20丢弃。
参考上述试剂吸取方法，当混匀组件120在第二工位12时，通过试剂移液单元310从存储单元320上吸取试剂加入至反应器20中，试剂的吸取包括如下子步骤：
提供试剂移液单元310和至少两个用于存储试剂的存储单元320，将试剂盛放在存储单元320的多个存储部321上的试剂容器内。
将存储部321跟随存储单元320运动，使试剂移液单元310于抵达至吸液工位14的存储部321上的试剂容器中吸取试剂。
使每个存储单元320执行的动作序列或任务可循环重现的最短时间窗口等于第一周期，即存储单元320连续两次执行同一动作的最小时间间隔等于第一周期。从其中一个存储单元320第一次带动试剂朝吸液工位14运动时起，依次错开一个第二周期所间隔的时间先后使其它存储单元320带动试剂朝相应的吸液工位14运动。
在一些实施例中，存储单元320的运动速度不成为免疫分析仪测试通量的瓶颈时，试剂的吸取包括如下子步骤：
提供试剂移液单元310和至少两个用于存储试剂的存储单元320，将试剂盛放在存储单元320的多个存储部321上的试剂容器内。
将存储部321跟随存储单元320运动，使试剂移液单元310于抵达至吸液工位14的存储部321上的试剂容器中吸取试剂。
使多个存储单元320的动作序列同步串行，即多个存储单元320在工作周期内的动作序列同步，在工作周期间串行，在每个工作周期内每个存储单元320都可将目标存储部321定位至吸液工位14以供试剂移液单元310吸取试剂，但每个工作周期只需一个存储单元320将目标存储部321定位至吸液工位14以供试剂移液单元310吸取试剂。总之，任一个工作周期，使其中的一个存储单元将存储部321定位至吸液工位14以供试剂移液单元310吸取试剂。
对于同一存储单元320，盛放相应分析项目所需的全部试剂组分。使试剂移液单元310与存储单元320的数量相等，且每个存储单元320分别对应一个试剂移液单元310。
参考上述稀释方法，当需要样本稀释时，在第二工位12处向反应器20中加入除稀释液成分的其它试剂组分之前，向反应器20中的样本加入稀释液进行稀释以形成稀释样本。
对于单个反应器20，以一步法测试为例，其在免疫分析仪10上的工作流程如下：第一，通过转移组件220从供给盘将空置且洁净的反应器20放置在处于初始工位13的混匀组件120上；第二，运输组件110带动混匀组件120运动到第一工位11，样本移液单元411向位于第一工位11处的反应器20中加入样本；第三，运输组件110带动混匀组件120运动到第二工位12，试剂移液单元310向位于第二工位12处的反应器20中加入试剂，混匀组件120使反应器20中的样本和试剂混匀；第四，转移组件220将混匀处理完毕的反应器20从混匀组件120经孵育进出工位15移入旋转盘210的孵育位213； 第五，孵育完毕后，转移组件220将反应器20在孵育进出工位15将其从孵育位213移出、并从清洗移入工位16转移至旋转盘210的清洗位212上；第六，清洗分离完毕后，向反应器20中加入信号试剂，转移组件220将反应器20在清洗移出工位17将其从清洗位212移出并放入到信号试剂混匀单元430混匀，然后转移组件220将信号试剂混匀完成后的反应器从测量进出工位18转移至旋转盘210的测量位211上，通过测量器230对反应器20中的光信号进行测量；第六，通过吸废液组件240将测量完成后反应中的废液吸除；第七，转移组件220将反应器20从测量进出工位18将反应器20移出旋转盘210、并将其丢弃至丢弃站。
当进行延时一步法和两步法测试，转移组件220可将孵育后或清洗后的反应器20再次移入到混匀装置100的混匀组件120中加入第二试剂和混匀，混匀完成后，转移组件220再将混匀处理完毕的反应器20移入反应装置200上进行孵育、清洗分离和测量。
