Description

样本分析仪的清洗控制方法及样本分析仪 技术领域
本发明涉及样本分析仪技术领域，特别是涉及一种样本分析仪的清洗控制方法及样本分析仪。
背景技术
在全自动样本分析仪中，由于采样针、搅拌器和反应容器等需要接触反应液，往往存在交叉污染的问题，因此，上述采样针、搅拌器和反应容器在使用前和使用后往往需要进行清洗，以避免交叉污染导致的分析结果不准确的问题。
传统的样本分析仪中，若当前测试存在交叉污染的风险时，往往会对测试过程中使用的所有器件进行清洗操作，如对自动样本分析仪上采样针、搅拌器和所有反应容器等器件均进行清洗操作。例如，采用同一种性质的清洗液对所有容器进行清洗，或者同时使用两种不同性质的清洗液对所有容器进行清洗。但由于交叉污染的属性差异，若只使用同一种性质的清洗液，不能适用于所有交叉污染属性所需的清洗操作，清洗效果不佳。若直接使用两种不同性质的清洗液进行清洗，则多余一种清洗液的清洗也会产生潜在的污染风险，且存在资源浪费，清洗效果不佳。
发明内容

具体实施方式
为了使本发明的技术方案更加清楚，以下结合附图，对本发明的样本分析仪的清洗控制 方法及样本分析仪作进一步详细的说明。应当理解，此处所描述的具体实施例仅用以解释本发明并不用于限定本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本发明一实施例提供了一种样本分析仪的清洗控制方法，用于根据目标器件的不同污染属性，自动对目标器件进行针对性的清洗，解决目标器件的污染状况，并提高清洗效果，节约资源。其中，目标器件的污染属性可以根据目标器件使用的试剂之间是否发生化学反应进行确定。
本实施例中，为实现样本分析仪的智能化清洗，可以在样本分析仪上预先存储有清洗参数表。该预设的清洗参数表中可以记录各种试剂之间的交叉污染关系(即各种试剂是否存在化学反应)，以及解除各个交叉污染关系所需的预设清洗操作信息，根据该预设清洗操作信息可以获知解除相应的交叉污染关系所需执行的清洗操作。可选地，该预设清洗操作信息可以包括解除交叉污染关系所需使用的预设试剂及预设清洗次数等信息。在该预设的清洗参数表中，每种交叉污染关系对应一个预设的清洗操作信息，即交叉污染关系与解除该交叉污染关系所需的清洗操作是一一对应的，从而可以实现对不同交叉污染关系的针对性清洗，保证测试结果的准确性，提高清洗效果并节约清洗剂。可选地，预设的清洗参数表还包括污染源和污染对象；污染源包括试剂的类型和/或组分、样本或反应生成物中的一种或多种；污染对象包括试剂的类型和/或组分、样本中的一种或多种。
具体地，如图1所示，上述方法包括如下步骤：
S100、获取当前操作步骤的当前操作信息，以及当前操作步骤所需使用的目标器件的历史操作信息；具体地，当前操作步骤的当前操作信息包括执行该当前操作步骤所需使用的目标器件以及该目标器件完成当前操作步骤所需使用的试剂等。该目标器件的历史操作信息包括该目标器件在执行当前操作步骤之前完成的历史操作步骤，以及完成对应的历史操作步骤所使用的试剂/清洗剂以及试剂/清洗剂的使用次数等等。例如，该，目标器件的历史操作信息可以为该目标器件在执行当前操作步骤之前的上一个操作步骤，以及上一个操作步骤使用的试剂/清洗剂，以及试剂/清洗剂的使用次数等等。
S200、根据目标器件的历史操作信息及当前操作步骤的当前操作信息，从预设的清洗参数表中获得目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系，及解除交叉污染关系对应的预设清洗操作信息。具体地，该预设的清洗参数表中可以记录目标器件的历史操作步骤所使用的试剂/清洗剂，与目标器件的当前操作步骤所使用的试剂/清洗剂之间存在的交叉污染关系，以及解除交叉关系对应的预设清洗操作信息。进一步地该预设清洗操作信息可以包括解除交叉污染关系所需的预设清洗剂以及预设清洗次数。
S300、当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系未被解除时，则按照预设清洗操作信息对所述目标器件进行清洗，或者根据所述目标器件的历史操作信息和所述预设操作信息对所述目标器件进行清洗。具体地，处理器通过查找预设的清洗参数表，可以获知目标器件的历史操作步骤与当前操作步骤之间是否存在交叉污染关系。可选地，若处理器能够从预设的清洗参数表中获得该目标器件的当前操作步骤与历史操作步骤之间的交 叉污染关系，则可以根据该查询获得的交叉污染关系对应的预设清洗操作信息对目标器件进行清洗，以解除目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系，保证当前操作步骤的结果准确。若处理器从预设的清洗参数表中未获得当前操作步骤与历史操作步骤之间的交叉污染关系，则可以认为该目标器件的当前操作步骤与历史操作步骤之间不存在交叉污染关系。
可选地，当目标器件历史操作步骤与当前操作步骤之间的交叉污染关系未被解除时，可以控制该目标器件对应的清洗装置按照预设清洗参数中的预设清洗操作信息对目标器件进行清洗。例如，目标器件的历史操作步骤为S1，当前操作步骤为S0，可以通过查询该预设的清洗参数表，目标器件的历史操作步骤S1与当前操作步骤S0之间存在交叉污染关系R1，以及解除该交叉污染关系R1所需的预设清洗操作信息为I1。则当目标器件的历史操作步骤S1与当期操作步骤S0之间的交叉污染关系R1未被解除时，可以按照该预设的清洗操作信息I1对目标器件进行清洗。若目标器件的当前操作步骤与历史操作步骤之间的交叉污染关系已经被解除时，则可以控制该目标器件执行当前操作步骤S0，或者控制该目标器件对应的清洗装置采用清水等清洗剂对目标器件清洗后，再控制该目标器件执行当前操作步骤S0。
可选地，在其他实施例中，当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系未被解除时，可以根据目标器件的历史操作信息和预设清洗操作信息对目标器件清洗。进一步地，可以根据目标器件的历史操作信息和预设清洗操作获得解除当前交叉污染关系所需的目标清洗操作信息，按照该目标清洗操作信息对目标器件进行清洗，以简化目标器件的清洗操作，具体清洗控制方法可参见下文中的描述。可选地，该历史操作信息包括目标器件的历史操作所使用的清洗剂或样本，以及使用清洗剂/样本的次数等等。
本实施例中，通过分别判断各个目标器件是否存在交叉污染，当该目标器件的交叉污染未被解除时，再对目标器件进行针对性的清洗。因此，本实施例的样本分析仪的清洗控制方法，通过只对存在交叉污染关系的目标器件进行清洗，能够简化样本分析仪的清洗操作，节省试剂或清水等资源，优化清洗效果，提高清洗效率。
可选地，上述预设的清洗参数表中的预设清洗操作信息包括预设清洗剂和预设清洗次数，其中，预设清洗剂可以包括酸性清洗剂、碱性清洗剂、其他洗液或清水中的一种或多种，其中，其他洗液是指除酸性清洗剂和碱性清洗剂之外的其他属性的试剂。例如，该其他清洗剂可以为含有表面活性剂或其他溶剂的试剂。其中，上述的酸性清洗剂、碱性清洗剂或其他洗液具体采用何种试剂，可以根据具体地交叉污染关系进行确定。进一步地，可以预先设定上述各种预设清洗剂的优先级排序，例如，各种优先级的排序可以为酸性清洗剂＝碱性清洗剂＞其他清洗剂＞清水。该各种预设清洗及的优先级的排序可以存储于预设的清洗参数表中，或设定为程序默认的优先级排序。
该预设试剂可以根据目标器件的当前测试步骤与历史测试步骤之间的交叉关系进行预先设置，该预设试剂应当能够解除上述的交叉污染关系。可选地，预设清洗次数应当大于或等于零，该预设清洗次数可以根据目标器件的当前测试步骤与历史测试步骤之间的交叉污染关系，以及解除该交叉污染关系所使用的预设试剂的清洗效果进行预先设置。
可选地，根据预设清洗操作信息对目标器件进行清洗的步骤还包括：
选用酸性清洗剂对目标器件，进行第一预设清洗次数的清洗操作；和/或
选用碱性清洗剂对所述目标器件，进行第二预设清洗次数的清洗操作；和/或
选用其他清洗剂对所述目标器件，进行第三预设清洗次数的清洗操作；
选用清水对所述目标器件，进行第四预设清洗次数的清洗操作。
下面举例说明上述的清洗方式，其仅用于清楚的说明本实施例的清洗方式，并不用于将上述的清洗方式限定于以下的清洗方式：
例如，针对交叉污染关系R1，处理器可以从预设的清洗参数表中获知解除该交叉污染关系R1的预设清洗操作信息为，“预设清洗剂：酸性清洗剂；预设清洗次数：第一预设清洗次数”，则当目标器件的当前操作步骤与历史操作步骤之间存在未被解除的交叉污染关系R1时，处理器可以按照预设清洗操作信息，控制该目标器件对应的清洗装置选用酸性清洗剂，并对目标器件进行第一清洗次数的清洗，之后使用清水清洗。
例如，针对交叉污染关系R2，处理器可以从预设的清洗参数表中获知解除该交叉污染关系R1的预设清洗操作信息为，“预设清洗剂：碱性清洗剂；预设清洗次数：第二预设清洗次数”，则当目标器件的当前操作步骤与历史操作步骤之间存在未被解除的交叉污染关系R2时，处理器可以按照预设清洗操作信息，控制该目标器件对应的清洗装置选用碱性清洗剂，并对目标器件进行第二清洗次数的清洗，之后，使用清水清洗。
例如，针对交叉污染关系R3，处理器可以从预设的清洗参数表中获知解除该交叉污染关系R3的预设清洗操作信息可以为，“第一预设清洗次数的酸性清洗剂清洗，第三预设清洗次数的其他清洗剂清洗，第四预设清洗次数的水清洗”，则当目标器件当前操作步骤与历史操作步骤之间存在未被解除的交叉污染关系R3时，处理器可以按照预设清洗操作信息，控制该目标器件对应的清洗装置首先选用酸性清洗剂，并对目标器件进行第一清洗次数的清洗，之后，选用其他清洗剂对目标器件进行第三预设清洗次数的清洗，最后，使用清水清洗进行第四预设次数的清洗。
当然，在其他实施例中，处理器还可以按照预设清洗操作信息和目标器件的历史操作信息对目标器件进行清洗，具体可参见下文中的描述。
进一步地，当解除同一个交叉污染关系对应的预设清洗剂为多种时，还可以根据各个预设清洗剂的清洗效果对多个预设清洗剂的优先级进行排序，获得优先级排序，其中各个预设清洗剂的清洗效果根据使用量及清洗次数获得。例如，使用少量酸性清洗剂或碱性清洗剂清洗一次即可解除该交叉污染关系，而使用其他洗液需要清洗三次才能解除同一交叉污染关系，则针对该交叉污染关系，可以认为该酸性清洗剂或碱性清洗剂的优先级高于其他洗液的优先级。本实施例中，预设清洗操作信息还包括多种预设清洗剂的优先级排序，通过将同一交叉污染关系对应的多种预设清洗剂的优先级排序预先存储于预设的清洗参数表中，使得样本分析仪能够根据预设的清洗参数表及实际应用场景，灵活的选择清洗操作，进一步提高了其智能化程度，便于使用。
具体地，上述方法还可以包括如下步骤：
当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系未被解除时，则可以从预设的清洗参数表中获取一个或多个预设清洗剂的优先级排序；具体地，针对每一个交叉污染关系均可以设置解除该交叉污染关系的一个或多个预设清洗剂，并设置该一个或多个预设清洗剂的优先级排序。当解除该交叉污染关系对应的预设清洗剂有且仅有一个时，则该唯一的预设清洗剂始终具有最高的优先级。
根据预设清洗剂的优先级排序，选取优先级最高的预设清洗剂对目标器件进行清洗。本实施例中，通过选取优先级最高的预设清洗剂对目标器件进行清洗，不仅可以有效的解除交叉污染关系，减少二次污染，而且可以减少预设清洗剂的用量和/或清洗次数，从而能够减少资源浪费。
进一步地，预设清洗操作信息还可以包括是否强制使用预设清洗操作信息指定的预设清洗剂的清洗参数，例如，该清洗参数可以采用“是”或“否”的方式展示于预设的清洗参数表中。当该预设的清洗参数表中的清洗参数显示为“是”时，其可以用于表示解除该交叉污染关系需要强制使用预设清洗操作信息指定的预设清洗剂；当该预设的清洗参数表中的清洗参数显示为“否”时，其可以用于表示解除该交叉污染关系无需强制使用预设清洗操作信息指定的预设清洗剂，可采用替代清洗剂，例如，替代清洗剂可以采用其他洗液。此处仅举例说明，其具体展示方式可以根据实际情况进行确定，此处不做具体限定。
若需强制使用预设清洗剂，则当该预设清洗操作信息指定的预设清洗剂不可用时，则无法采用其他优先级较低的预设清洗剂进行替代。具体地，如图2所示，上述方法还包括如下步骤：
S400、判断目标器件历史操作步骤与当前操作步骤之间的交叉污染关系是否解除；
S600、判断预设清洗操作信息指定的预设清洗剂是否可用；可选地，可以将该预设清洗操作信息指定的的预设清洗剂是否耗尽，和/或是否失效，和/或是否污染，作为其是否可用的判断标准。例如，当该预设清洗操作信息指定的预设清洗剂已经耗尽时，则判定该预设清洗操作信息指定的预设清洗剂不可用。当该预设清洗操作信息指定的预设清洗剂未耗尽且未失效且未被污染时，则可以判定预设清洗操作信息指定的预设清洗剂可用。
S610、判断是否强制使用预设清洗操作信息指定的预设清洗剂。具体地，当处理器从预设的清洗参数表中获得的清洗参数为需要强制使用优先级最高的预设清洗剂时，则说明解除该交叉污染关系需要强制使用预设清洗操作信息指定的预设清洗剂。当处理器从预设的清洗参数表中获得的清洗参数为无需使用优先级最高的预设清洗剂时，则说明解除该交叉污染关系无需强制使用预设清洗操作信息指定的预设清洗剂，可以采用其他预设清洗剂进行替代。
若预设清洗操作信息指定的预设清洗剂不可用，且解除该交叉污染关系需要强制使用预设清洗剂时，则执行步骤S620，暂停目标器件的清洗操作，并发出报警提示信息，直至该预设清洗操作信息指定的预设清洗剂可用时，再执行该目标器件的清洗操作。同时，该样本分析仪还可以发出报警提示信息，以提醒工作人员及时补充清洗剂。
若预设清洗操作信息指定的预设清洗剂不可用，且解除该交叉污染关系无需强制使用预设清洗操作信息指定的预设清洗剂时，则执行步骤S700，按照预设的替代清洗操作对目标器 件进行清洗。该预设的替代清洗操作能够消除任意的交叉污染关系，因此，当解除该交叉污染关系无需强制使用预设清洗操作信息指定的预设清洗剂时，则可以采用该通用的替代清洗操作对目标清洗操作进行操作，以简化样本分析仪的清洗过程，节省资源并提高工作效率。例如，该替代清洗操作可以为采用其他洗液对目标器件清洗一次；或者采用酸性清洗剂对目标器件清洗两次；或者采用清水对目标器件清洗一次等等，此处不做具体限定。
当前，在其他实施例中，若无需强制使用预设清洗操作信息指定的预设清洗剂，则当该预设清洗操作信息指定的预设清洗剂不可用时，则可以采用其他的预设清洗剂进行替代。具体地，上述方法还可以包括如下步骤：
若预设清洗操作信息指定的预设清洗剂不可用，且解除该交叉污染关系无需强制使用预设清洗操作信息指定的预设清洗剂时，则根据预设的清洗参数表中的预设清洗剂的优先级排序，从多个预设清洗剂中选取除预设清洗操作信息指定的预设清洗剂之外的其他预设清洗剂，对目标器件进行预设清洗次数的清洗。
例如，解除目标器件的当前操作步骤与历史操作步骤之间的交叉污染关系的多种预设清洗剂的优先级排序为：酸性清洗剂＞其他清洗剂＞清水。此时，若酸性清洗剂不可用时，则判断其他清洗剂是否可用，若其他清洗剂可用，则可以选取其他清洗剂对目标器件进行清洗。若上述各种清洗剂均不可用，则暂停目标器件的清洗操作，并发出报警提示信息。
进一步地，上述方法还包括如下步骤：
当目标器件采用的实际清洗剂与预设清洗操作信息中指定的预设清洗剂不一致时，在预设的清洗参数表中标记警告信息。例如，该警告信息可以通过字符或数字等方式标识于预设的清洗参数表中。这样，处理器或用户能够获知该不一致的清洗操作，并判断该不一致的清洗操作是否会影响当前操作的结果准确性，从而起到了一定的污染风险预测及控制的作用。
下面举例说明上述的目标器件的清洗方法的具体实现过程：
Figure PCTCN2017105047-appb-000001
如上表所示，目标器件当前操作步骤与历史操作步骤之间存在未被解除的交叉污染关系R1，解除该交叉污染关系R1对应的预设清洗操作可以为使用预设清洗剂A1清洗两次。当解除该交叉污染关系R1需强制使用该预设清洗剂A1，且该预设清洗剂A1可用，此时，可以控制目标器件对应的清洗装置采样预设清洗剂A1对目标器件清洗两次。若预设清洗剂A1不可用，则停止目标器件的清洗，并报警。
若解除该交叉污染关系R1无需强制使用该预设清洗剂A1，且该预设清洗剂A1不可用时，则可以控制目标器件对应的清洗装置采用预设的替代清洗操作对目标器件进行清洗，以解除该交叉污染关系R1。同时，处理器还可以在预设清洗参数表中进行标记，以表明该目标器件的实际清洗操作并未采用指定的预设清洗剂A1。
再如，在另一个实施例中，
Figure PCTCN2017105047-appb-000002
如上表所示，目标器件的当前操作步骤与历史操作步骤之间存在未被解除的交叉污染关系R1，解除该交叉污染关系R1对应的预设清洗操作可以为使用预设清洗剂A2清洗一次或使用预设清洗剂A1清洗两次。当解除该交叉污染关系R1需强制使用优先级最高的预设清洗剂A2，且该预设清洗剂A2可用，此时，可以控制目标器件对应的清洗装置采样预设清洗剂A2对目标器件清洗一次。若预设清洗剂A2不可用，则停止目标器件的清洗，并报警。
若解除该交叉污染关系R1无需强制使用优先级最高的预设清洗剂A2，且优先级最高的预设清洗剂A2不可用时，则可以控制目标器件对应的清洗装置采用预设清洗剂A1对目标器件清洗两次。同时，处理器还可以在预设清洗参数表中进行标记，以表明该目标器件的实际清洗操作并未采用优先级最高的预设清洗剂。
作为进一步地改进，如图3所示，上述步骤S400还包括如下步骤：
获取目标器件的历史操作信息；其中，目标器件的历史操作信息可以包括该目标器件的历史操作，及历史操作所使用的清洗剂及清洗剂的使用次数等信息。可选地，该历史操作信息可以为该目标器件在当前操作步骤之前的上一操作步骤对应的操作信息，该上一操作步骤的操作信息可以作为该目标器件的历史操作信息存储于预设的历史操作表中，该历史操作表可以实时更新。当然，该历史操作信息可以为该目标器件在当前操作步骤之前的所有历史操作信息，该历史操作信息可以存储于预设的历史操作表中，该历史操作表可以实时更新。即每当目标器件执行一个操作步骤，可以更新一次该历史清洗参数表。
S410、根据目标器件的历史操作信息，获得目标器件已使用过的一种或多种预设清洗剂及采用各种预设清洗剂的已清洗次数。具体地，通过获取的目标器件的历史操作信息，可以获知该目标器件在该当前操作步骤之前吸取过哪些清洗剂以及吸取清洗剂的次数等信息，从而可以获得目标器件已使用的预设清洗剂的种类及使用各种预设清洗剂进行清洗的已清洗次数。
S420、根据目标器件已使用过的一种或多种预设清洗剂及采用各种预设清洗剂的已清洗次数，判断目标器件使用预设清洗操作信息中指定的预设清洗剂进行清洗的已清洗次数，是否小于目标器件对应的预设清洗操作信息中指定的预设清洗次数；
若目标器件使用所述预设清洗操作信息中指定的预设清洗剂进行清洗的已清洗次数，小 于目标器件对应的预设清洗操作信息中指定的预设清洗次数时，则可以执行步骤S430，判定目标器件的历史操作步骤与当前操作步骤之间的交叉污染未解除，此时需要对该目标器件进行清洗后，才可以执行当前操作步骤，以避免该目标器件的当前操作步骤与历史操作步骤之间的交叉污染关系，影响当前操作步骤的结果准确性。
若目标器件使用预设清洗操作信息中指定的预设清洗剂进行清洗的已清洗次数大于或等于目标器件对应的预设清洗操作信息中指定的预设清洗次数，则判定目标器件的历史操作步骤与所述当前操作步骤之间的交叉污染解除。此时，可以直接控制目标器件执行当前操作步骤，或首先控制目标器件的清洗装置采用清水等普通清洗清洗剂对目标器件进行清洗之后，再可控制该目标器件执行当前操作步骤。
进一步地，上述步骤S300进一步还包括：
S310、根据目标器件的历史操作信息，以及预设的清洗参数表中交叉污染关系对应的预设清洗操作信息，获得解除交叉污染关系所需的目标清洗操作信息，并按照目标清洗操作信息对目标器件进行清洗。可选地，该目标清洗操作信息可以包括解除目标器件的交叉污染关系所需的目标清洗剂，以及使用该目标清洗剂对目标器件进行清洗的目标清洗次数。其中，该目标清洗剂可以是预设清洗操作信息中指定的预设清洗剂，该目标清洗次数可以是预设清洗操作信息指定的预设清洗次数，与目标器件采用该指定的预设清洗剂进行清洗的已清洗次数之差。当目标器件采用指定的预设清洗剂进行清洗的已清洗次数为零时，则此时的目标清洗次数等于预设清洗操作信息指定的预设清洗次数。
例如，解除该目标器件的当前操作步骤与历史操作步骤之间的交叉污染关系所需的预设清洗操作信息表明，需要采用酸性清洗剂清洗两次；同时，根据目标器件的历史操作信息可以获知该目标器件已使用酸性清洗剂清洗一次。则解除当前交叉污染关系所需的目标清洗操作信息可以为，使用酸性清洗剂清洗一次。这样可以进一步简化目标器件的强化清洗操作，节省清洗剂和水的耗费量，节约资源，并且通过简化清洗操作步骤，能够提高样本分析仪的工作效率。
可选地，上述步骤S310进一步可以包括如下步骤：
根据目标器件使用预设清洗操作信息中指定的预设清洗剂进行清洗的已清洗次数，以及目标器件对应的预设清洗操作信息中指定的预设清洗次数，获得目标器件所需的目标清洗次数。其中，该目标清洗剂可以是预设清洗操作信息中指定的预设清洗剂，该目标清洗次数可以是预设清洗操作信息指定的预设清洗次数，与目标器件采用该指定的预设清洗剂进行清洗的已清洗次数之差。
采用预设的清洗参数中指定的预设清洗剂对目标器件进行目标清洗次数的清洗。例如，解除该目标器件的当前操作步骤与历史操作步骤之间的交叉污染关系所需的预设清洗操作信息表明，需要采用酸性清洗剂清洗两次；同时，根据目标器件的历史操作信息可以获知该目标器件已使用酸性清洗剂清洗一次。则解除当前交叉污染关系所需的目标清洗操作信息可以为，使用酸性清洗剂清洗一次。
进一步地，如图4所示，当目标器件的历史操作步骤与当前操作步骤之间未被解除的交 叉污染关系为多种时，上述步骤S310还可以包括如下步骤：
S311、根据预设的清洗参数表和目标器件的历史操作信息，分别获取解除各种交叉污染关系所需的目标清洗操作信息。具体地，处理器可以从预设的清洗参数表中获知该目标器件的当前操作步骤与该目标器件的哪些历史操作步骤之间存在交叉污染关系，并可以从预设的清洗参数表中获得解除各种交叉污染关系所需的预设清洗操作信息，即可以获得解除各种交叉污染关系所需的预设清洗剂及采用预设清洗剂进行清洗的预设清洗次数。之后，处理器可以根据各个交叉污染关系对应的预设清洗操作信息与目标器件的历史操作信息，获得解除各个交叉污染关系所需的目标清洗操作信息，该目标清洗操作信息的获得方法具体可参见上文中的描述。
S312、根据各种交叉污染关系所需的目标清洗操作信息判断目标器件的目标清洗操作是否能够合并简化。具体地，处理器可以根据各种交叉污染关系所需的目标清洗操作信息，判断采用同一清洗操作能否解除上述的多种交叉污染关系。
若各种交叉污染关系所需的目标清洗操作能够合并简化，即能够采用同一清洗操作解除上述的多种交叉污染关系时，则执行步骤S313，获取多个目标清洗操作信息中清洗要求最高的目标清洗操作信息，按照清洗要求最高的目标清洗操作信息对目标器件进行清洗；其中，清洗要求包括解除同一种交叉污染关系所需的目标清洗剂、目标清洗次数、解除该交叉污染关系对应的多种目标清洗剂的优先级排序以及是否强制使用预设清洗操作信息中指定的目标清洗剂。本实施例中，通过采用清洗要求最高的目标清洗操作信息对目标器件进行清洗，既可以保证该目标器件的清洗效果，还可以一次性解除多种交叉污染关系，节省清洗剂及清水的使用量，节约资源，且能够提高该样本分析仪的处理效率。当各种交叉污染关系所需的目标清洗操作不能够合并简化时，则可以执行步骤S314，分别按照各种交叉污染关系对应的目标清洗操作信息对目标器件进行清洗，直至解除所有的交叉污染关系。
进一步地，当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系解除时，则控制目标器件直接执行当前操作步骤，不执行清洗操作。当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系已经解除时，则无需插入强化清洗步骤，可以控制目标器件执行当前操作步骤。更进一步，当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系已经解除时，则可以直接执行当前操作步骤，或者控制清洗装置采用清水等普通清洗方式对目标器件进行清洗，之后控制目标器件执行当前操作步骤。
以下举例说明上述步骤的具体实现过程：
Figure PCTCN2017105047-appb-000003
如上表所示，处理器可以从预设的清洗参数表中，获知目标器件的当前操作步骤与历史操作步骤之间存在交叉污染关系R1，解除该交叉污染关系所需执行的清洗操作步骤为：使用 预设清洗剂A对目标器件清洗两次。同时，处理器可以获得该目标器件的历史操作信息，并从该历史操作信息中获知该目标器件已使用预设清洗剂A进行两次清洗，则处理器可以根据目标器件的交叉污染关系R1对应的预设清洗操作信息，以及目标器件的历史操作信息，判定目标器件的当前操作步骤与历史操作步骤之间的交叉污染关系R1已经被解除，此时可以直接执行当前操作步骤，或者清洗装置采用清水等普通清洗方式对目标器件进行清洗，之后控制目标器件执行当前操作步骤。此处仅示例性的说明上述步骤的实现过程，针对每一种交叉污染关系，均可以采用类似的方法进行判断交叉污染关系是否解除。
进一步地，当该目标器件的当前操作步骤与历史操作步骤之间存在多种交叉污染关系时，则需分别判断各种交叉污染关系是否均已被解除，只有当该目标器件的当前操作步骤与历史操作步骤之间存在多种交叉污染关系均被解除时，可以清洗装置采用清水等普通清洗方式对目标器件进行清洗，之后控制目标器件执行当前操作步骤。
可选地，上述方法还包括如下步骤：
若根据目标器件的历史操作信息及当前操作步骤的当前操作信息，从预设的清洗参数表中未获得目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系时，则执行步骤S500，按照预设的普通清洗操作对目标器件进行普通清洗。具体地，若处理器从预设的清洗参数表中未获得目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系时，则可以说明该目标器件的历史操作步骤与当前操作步骤之间不存在交叉污染，此时可以按照预设的普通清洗操作对目标器件进行普通清洗，之后控制目标器件执行当前操作步骤。这样，不仅可以节省预设清洗剂的使用量，节约资源，还可以避免预设清洗剂对当前操作步骤造成二次污染的问题，保证当前操作步骤的准确性。可选地，上述的普通清洗操作可以是采用清水对目标器件进行清洗的操作，当然，上述的普通清洗操作还可以是采用除上述预设清洗剂之外的其他清洗剂进行清洗的操作。
本实施例中，通过分别判断各个目标器件是否存在交叉污染，当该目标器件的交叉污染已经被解除，或其不存在交叉污染时，则可以不执行清洗操作或只执行普通清洗操作；当该目标器件的交叉污染未被解除时，再对目标器件进行针对性的清洗。因此，本实施例的样本分析仪的清洗控制方法，通过只对存在交叉污染关系的目标器件进行清洗，能够简化样本分析仪的清洗操作，节省试剂或清水等资源，优化清洗效果，提高清洗效率。
可选地，上述目标器件可以是反应容器、搅拌器、试剂针或采样针。可选地，该反应容器可以为反应杯、试管或样本玻片等等，该搅拌器可以为搅拌杆等。针对每一种目标器件，均可以根据预设的清洗参数表和该目标器件的历史操作信息，获得该目标器件的目标清洗操作信息，并按照目标清洗操作对目标器件进行清洗，其具体清洗方式可以采用上述任一实施例的清洗方法。
进一步地，上述各个目标器件的数量可以为多个，针对每一个目标器件均可以按照上述的清洗方法进行清洗。可选地，在获取当前操作步骤的当前操作信息的步骤之前，上述方法还包括如下步骤：
获取当前测试项目的测试信息，当前测试项目包括一个或多个操作步骤；
根据当前测试项目的测试信息判断当前测试项目所需的目标器件的数量；
若当前测试项目所需的反应容器的数量小于样本分析仪上可用的目标器件的数量时，则根据预设的清洗参数表对预设的第一数量的目标器件进行清洗，之后执行测试项目；其中，预设的第一数量大于或等于当前测试项目所需的目标器件的数量，预设的第一数量小于样本分析仪上可用的目标器件的数量。即在本实施例中，当前测试项目需要使用几个目标器件，则清洗几个目标器件，而不是一次性完成所有目标器件的清洗，从而减小清洗剂及水的使用量，节约资源，并且通过减少清洗步骤，提高了样本分析仪的工作效率。
例如，当该目标器件为试剂针时，则可以获取试剂针的当前分注步骤需要吸取的清洗剂。同时，处理器可以获取该试剂针的历史分注信息，从而获知该试剂针在当前分注步骤之前吸取过哪些清洗剂。具体地，当试剂针吸排清洗剂a1之后，按照测试顺序，试剂针需要继续吸排清洗剂b1。则在试剂针吸排清洗剂b1之前，可以通过查询预设的清洗参数表，获知该清洗剂a1和分注清洗剂b1之间存在交叉污染关系r1及解除该交叉污染关系r1所需的预设清洗操作信息。例如，解除该交叉污染关系r1所需的预设清洗操作信息对应的清洗操作为，使用酸性清洗剂清洗一次。之后，处理器可以通过试剂针的历史分注信息获知，在试剂针的两次吸排动作之间(吸取清洗剂a1和吸取清洗剂b1之间)，试剂针未进行过吸排解除交叉污染关系r1所需酸性清洗剂的操作，则可以判定该交叉污染关系并未解除，此时可以首先使用酸性清洗剂对试剂针清洗一次，之后再控制试剂针吸排清洗剂b1。
进一步地，若此时酸性清洗剂不可用，且解除该交叉污染关系r1需强制使用该酸性清洗剂时，则暂停试剂针的清洗操作，并报警。若此时酸性清洗剂不可用，且解除该交叉污染关系r1无需强制使用酸性清洗剂时，则可以按照预设的替代清洗操作对试剂针进行清洗。
若通过查询预设的清洗参数表，获知该清洗剂a1和清洗剂b1之间不存在交叉污染关系r1，或者交叉污染关系r1已经被解除，则可以使用清水等普通清洗剂对试剂针进行清洗，之后控制试剂针吸排分注清洗剂b1。或者，该清洗剂a1和清洗剂b1之间不存在交叉污染关系，或者交叉污染关系r1已经被解除时，可以控制试剂针直接执行当前分注步骤。
更进一步地，该试剂针的数量可以为多个，针对每一个试剂针均可以按照上述的清洗方法进行清洗。针对每一个试剂针，在其执行当前分注步骤之前，必须消除该试剂针的当前分注步骤与其历史分注步骤之间的所有交叉污染关系。若存在未解除的交叉污染关系，且解除该交叉污染关系的清洗剂不可用时，则可以将当前分注步骤分配至其他已解除污染关系的试剂针。承接上例，该试剂针的数量可以为两个，为便于表述，两个试剂针可以分别记为第一试剂针和第二试剂针，其中第一试剂针上的交叉污染关系r1已经解除，第二试剂针上的交叉污染关系r1尚未被解除，则可以将当前分注步骤分配至第一试剂针。若两个试剂针上的交叉污染关系r1均未被解除，则可以暂停执行两个试剂针的清洗操作，并报警。
再如，当该目标器件为反应容器时，如该目标器件为反应杯时，则可以在向该反应杯内加注样本或清洗剂之前，可以获取当前操作步骤需要向反应杯添加的样本/清洗剂c1。同时，处理器还可以获取该反应杯的历史测试信息，该历史测试信息可以包括该反应杯在当前操作步骤之前盛放过哪些清洗剂或样本。具体地，在执行当前测试步骤之前，处理器可以根据当 前需要向反应杯内添加的样本/清洗剂c1，以及该反应杯在当前操作步骤之前接触过的清洗剂/样本d1、e1及f1，从预设的清洗参数表中获取当前需要向反应杯内添加的样本/清洗剂c1，与反应杯之前接触过的清洗剂/样本d1、e1及f1之间的交叉污染关系，以及各个交叉污染关系对应的预设清洗操作信息。例如，样本/清洗剂c1与样本/清洗剂d1之间存在交叉污染关系r2，样本/清洗剂c1与样本/清洗剂e1之间存在交叉污染关系r3，样本/清洗剂c1与样本/清洗剂f1之间不存在交叉污染。
处理器可以根据通过反应杯的历史测试信息，获得在当前操作步骤之前，是否对反应杯进行过解除上述交叉污染关系r2和r3对应的清洗操作，从而可以判断上述交叉污染关系r2和r3是否已经被解除。若根据预设的清洗参数表可以获知，解除上述交叉污染关系r2需要采用酸性清洗剂清洗两次，解除上述交叉污染关系r3需要采用酸性清洗剂清洗一次。且在当前操作步骤之前，未对反应杯进行过解除交叉污染关系r2和r3的清洗操作，则由于解除上述交叉污染关系r2和r3所需使用的预设清洗剂相同，则可以采用酸性清洗剂对反应杯清洗两次，以通过同时解除上述交叉污染关系r2和r3。
若根据预设的清洗参数表可以获知，解除上述交叉污染关系r2需要采用碱性清洗剂清洗两次，解除上述交叉污染关系r3需要采用酸性清洗剂或碱性清洗剂清洗一次，且解除该交叉污染关系r3并不强制使用优先级较高的酸性清洗剂。且在当前操作步骤之前，已经采用碱性清洗剂对反应杯进行了一次清洗操作，此时可以采用碱性清洗剂对反应杯清洗一次，以通过同时解除上述交叉污染关系r2和r3。
进一步地，在当前测试项目所需的反应容器的数量小于样本分析仪上可用的反应容器的数量时，则可以对第一数量的反应容器进行清洗，其中，第一数量小于样本分析仪上可用的反应容器的数量。相对于传统的清洗所有反应容器的清洗方式，可以十分有效的节省用于清洗的耗材(清洗剂或清水等)的使用量，降低仪器的使用成本。进一步地，针对每一个反应容器，可以根据该反应容器的当前测试步骤与历史测试步骤，从预设的清洗参数表中获得该反应容器的清洗操作信息，从而根据预设的清洗操作信息对各个反应容器进行针对性的清洗，具体可参见上文的描述。
又如，该目标器件还可以是采样针。由于采样针在吐样的时候有可能会接触到反应容器内已添加的清洗剂/样本等，因此，采样针接触过的清洗剂/样本可能与当前采样步骤需要吸取样本之间存在交叉污染，在采样针执行当前采样步骤之前需要对采样针进行清洗操作，以完全消除交叉污染关系。具体地，该采样针的清洗控制可以类似于上述试剂针的清洗控制方法，具体可参见上文中的描述。
当然，在其他实施例中，该目标器件还可以是搅拌器等，该搅拌器的数量可以为多个。其具体控制方式与上述采样针的控制方式类似，具体可参见上文中的描述。
作为进一步地改进，上述方法还包括如下步骤：
在交互显示界面上显示预设的清洗参数表；本实施例中，该预设的清洗参数表中可以通过交互显示界面展示给用户，以便用户能够直观地获知清洗操作。可选地，该交互显示界面可以显示于与样本分析仪连接的终端显示屏上，如电脑、手机等的显示屏上。当然，该交互 显示界面还可以显示于样本分析仪上的显示装置上，此处不做具体限定。
通过交互显示界面获取预设的清洗参数表的参数更新信息；具体地，用户可以对显示于交互显示界面上的预设的清洗参数表内的预设清洗操作信息及交叉污染关系等进行增减或修改。当用户对预设的清洗参数表进行修改时，处理器可以根据该修改操作获得预设的清洗参数表的参数更新信息，并对应存储该参数更新信息。这样，用户可以根据实际的测试项目调整该清洗参数表，从而可以使该样本分析仪能够适用于多种不同的测试项目，提高仪器的通用性。
根据预设的清洗参数表的参数更新信息，获得更新后的清洗参数表，在交互显示界面上展示更新后的清洗参数表；可选地，当完成预设的清洗参数表的更新之后，可以在交互显示界面上展示该更新后的清洗参数表，以便用户使用。
当接收到操作开始指令后，从更新的清洗参数表中获得目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系，及交叉污染关系对应的预设清洗操作信息。具体地，根据更新的清洗参数表进行各个目标器件的清洗控制的方法，与上述根据原始的清洗参数表进行各个目标器件的清洗控制方法相似，具体可参见上文中的描述。
同时，如图5所示，本发明一实施例还提供了一种样本分析仪，该样本分析仪1用于对待测的样本进行分析检测，以得到相应的检测结果，满足使用需求。需要说明的是，待测的样本的具体种类不受限制，在一些实施例中，待测的样本包括固体样本或者液体样本。可以理解，对液体样本进行检测时，需要将液体样本置于样本容器如试管、微量杯等能够承载的反应容器中进行。进一步的液体样本包括但不限于血液样本。该样本分析仪可以包括控制装置、显示装置、样本存储装置11、试剂存储装置12、采样针14、试剂针15、样本孵育检测装置13、清洗装置16及搅拌器17。
其中，试剂存储装置12用于存储试剂，能够存储样本检测时所需要的各种试剂，方便选择所需的试剂，提高吸取试剂的效率。样本孵育检测装置13用于孵育样本，以使得样本与试剂充分反应，进而使得样本达到最佳的反应条件，方便样本参数的检测；同时样本孵育检测装置13还能对孵育完成后的样本进行检测，以得到样本的参数。采样针用于吸排样本，以实现将样本的转移。试剂针用于吸排试剂，以实现将试剂的转移。同时，采样针和试剂针还可以吸取清洗剂进行清洗，以避免交叉污染，保证样本检测的准确性。
为了提高试剂的转移速度，试剂针的数量为两个，分别为第一试剂针及第二试剂针，第一试剂针与第二试剂针能够分别将试剂存储装置12上的试剂转移到样本孵育检测装置13的反应容器中。可选地，采样针的数量也可以为多个。
可选地，样本存储装置11包括可转动且呈圆盘状的样本承载盘。样本承载盘能够承载多个样本。样本承载盘上开设多个样本放置孔，盛装样本的反应容器放置于样本放置孔中。多个样本放置孔以样本承载盘的圆心为基准沿样本承载盘的周向方向分布，样本承载盘上具有至少两圈的样本放置孔，这样能够增加样本承载盘承载样本的数量，提高样本的检测效率。
可选地，试剂存储装置12包括可转动且呈圆盘状的试剂承载盘，试剂承载盘能够存放多种试剂。可以理解的是，试剂承载盘中还可存放盛装有清洗剂的容器、盛装有去离子水的容 器或者盛装具有其他功能的液体。
可选地，搅拌器17设置于样本孵育检测装置13的周侧。搅拌器17用于对反应容器中的样本与试剂搅拌，使得样本与试剂混合均匀，进而保证样本与试剂的孵育效果，使得样本检测结果准确。进一步地，该搅拌器的数量可以多个。
可选地，清洗装置16包括用于对反应杯进行清洗的反应杯清洗机构161、用于对采样针进行清洗的样本针清洗机构162、用于对试剂针进行清洗的试剂针清洗机构163及用于对搅拌器进行清洗的搅拌杆清洗机构164。
可选地，控制装置包括处理器和存储器，存储器上存储有计算机程序，显示装置用于显示预设的清洗参数表；处理器用于执行上述任一实施例的方法。处理器可以用于获取当前操作步骤的当前操作信息，以及当前操作步骤所需使用的目标器件的历史操作信息；根据目标器件的历史操作信息及当前操作步骤的当前操作信息，从预设的清洗参数表中获得所述目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系及解除交叉污染关系对应的预设清洗操作信息；当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系未被解除时，则根据预设清洗操作信息对所述目标器件进行清洗。应当清楚的是，本实施例的样本分析仪的工作原理与上述方法中各个步骤的执行过程基本一致，具体可参见上文中的描述。
在一个实施例中，如图6所示，本发明一实施例还提供了一种样本分析仪200，其可以包括第一信息获取模块210、第二信息获取模块220以及控制模块230。其中，第一信息获取模块210用于获取当前操作步骤的当前操作信息，以及当前操作步骤所需使用的目标器件的历史操作信息。具体地，当前操作步骤的当前操作信息包括执行该当前操作步骤所需使用的目标器件以及该目标器件完成当前操作步骤所需使用的清洗剂等。该目标器件的历史操作信息包括该目标器件在执行当前操作步骤之前完成的历史操作步骤，以及完成对应的历史操作步骤所使用的清洗剂及清洗剂的使用次数等等。
第二信息获取模块220用于根据目标器件的历史操作信息及当前操作步骤的当前操作信息，从预设的清洗参数表中获得目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系及解除交叉污染关系对应的预设清洗操作信息。
控制模块230用于当目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系未被解除时，则按照预设清洗操作信息对目标器件进行清洗，或者根据目标器件的历史操作信息和预设操作信息对目标器件进行清洗。具体地，处理器通过查找预设的清洗参数表，可以获知目标器件的历史操作步骤与当前操作步骤之间是否存在交叉污染关系。可选地，若处理器能够从预设的清洗参数表中获得该目标器件的当前操作步骤与历史操作步骤之间的交叉污染关系，则可以根据该查询获得的交叉污染关系对应的预设清洗操作信息对目标器件进行清洗，以解除目标器件的历史操作步骤与当前操作步骤之间的交叉污染关系，保证当前操作步骤的结果准确。若处理器从预设的清洗参数表中未获得当前操作步骤与历史操作步骤之间的交叉污染关系，则可以认为该目标器件的当前操作步骤与历史操作步骤之间不存在交叉污染关系。
应当清楚的是，本实施例的样本分析仪的工作原理与上述方法中各个步骤的执行过程基本一致，具体可参见上文中的描述。
