技术领域
本申请涉及流体系统技术领域，例如涉及一种流体系统。
背景技术
通过流体系统运输试剂或样本进入流动池的过程，就是采用新流体替代此前充满流体系统的原有流体的过程。在这个过程中，新流体通常会先在流动的路径中消耗较多的体积，而后进入流动池中的新流体才能较为纯净。
相关技术中的流体系统，由于管路设计不合理，在流动池中参加生物或化学反应的新流体的体积远小于在路径中运输的体积，流体的利用率较低。这种额外的消耗通常是由两个原因所致：一是此前充满流体系统的原有流体会在壁面上留下残留物；二是流体系统中存在不能直接冲刷的死体积。这两个原因都会促使流体系统必须额外使用大量体积的新流体，才能冲刷掉壁面上的残留物，以及以分子扩散稀释的方式对死体积内无法冲刷的流体进行替换。

上述流体系统通过切换转换模块400的状态可以改变路径的连通方式，从而实现不同功能。当转换模块400处于第一状态时，转换模块400具有功能1-1：转换模块400将流体容器100和第一动力管道8进行连通，此时，驱动模块200能够驱动流体容器100内的流体向第一动力管道8中流动，因而，从流体容器100到转换模块400所经路径中的原有流体被推动至第一动力管道8暂存，便于后续进行排放或回收，并且从流体容器100到转换模块400所经路径被流体容器100内的流体填充；当转换模块400处于第二状态时，转换模块400具有功能2-1：转换模块400将流体容器100和流动池入口A连通，流动池出口B经转换模块400连通到第二动力管道9，因而，流体容器100内的流体可以通过转换模块400进入到流动池模块300中进行反应，此时流动池模块300中的原有流体已经被推动至第二动力管道9中暂存，以便进行后续的排放或回收。该流体系统以转换模块400为核心，对流体流动的路径和驱动力进行分配，使流体系统可以同时存在互相独立的不同路径，能够在发生反应之间向管道内填充流体同时清理管道中残留的流体，实现流体的高效运输，极大程度上加快反应进程，同时避免了流体的浪费。
在一实施例中，所述转换模块400处于所述第一状态时，第二动力管道9通过转换模块400与废料容器700或流体容器100连通，第二动力管道9内暂存的流体能够在驱动模块200的驱动下推送至废料容器700或流体容器100。即，当转换模块400处于第一状态时，转换模块400还具有功能1-2：转换模块400还可以将第二动力管道9和废料容器700或流体容器100连通，由于流体容器100连通于驱动模块200，驱动模块200和第二动力管道9连通，从而第二动力管道9内暂存的流体被推动至废料容器700排放或推送至流体容器100回收。
在一实施例中，所述转换模块400处于所述第二状态时，第一动力管道8通过转换模块400与废料容器700或流体容器100连通，第一动力管道8内暂存的流体能够在驱动模块200的驱动下推送至废料容器700或流体容器100。即，当转换模块400处于第二状态时，转换模块400还具有的功能2-2：转换模块400将第一动力管道8和废料容器700或流体容器100连通，由于流体容器100连 通于驱动模块200，驱动模块200和第一动力管道8连通，从而第一动力管道8内暂存的流体被推动至废料容器700排放或推送至流体容器100回收。
综上所述，当转换模块400处于第一状态时，可同时实现功能1-1和功能1-2；当转换模块400处于第二状态时，可同时实现功能2-1和功能2-2。也就是说，在反应过程中所需流体的输送和暂存流体的排放或回收可以同时进行，由此缩短了流体输送的时间，极大程度上加快反应进程，同时避免了流体的浪费。
继续参见图1，以下对本实施例提供的转换模块400、流体容器100、流体选择模块500、驱动模块200、路径切换模块600、流动池模块300以及废料容器700的功能和相关设置进行说明：
在本实施例中，转换模块400包括六个接口，其中，接口c连接流动池入口管道11，接口d连接流动池出口管道12，接口e连接第二动力管道9，接口f连接分流管道10，接口a连接第一动力管道8，接口b连接公共管道7。转换模块400主要的功能是管道切换，通过控制驱动模块200与流动池模块300、路径切换模块600、流体选择模块500之间的连通与断开，从而形成不同的流动路径。转换模块400应至少有两个状态：
第一状态：接口a连通接口b、接口c连通接口d、接口e连通接口f；
第二状态：接口f连通接口a、接口b连通接口c、接口d连通接口e。
根据转换模块400的设计需要，可使用二位六通转换阀，或者是根据特殊要求设计的转换阀。转换阀属于旋转剪切阀，是后者的一个细化分类。此外，还可以使用多个二位三通电磁阀和二位二通电磁阀以及对应的基板组成的阀组，从而实现上述功能。
流体容器100连通有流体管道1、第一准备管道3、流体回收管道5。流体容器100主要的功能是存放多种流体，包括待使用的流体，使用后回收的流体，以及驱动模块200所需的起填充作用的流体，上述的每类流体都可以是一种或多种。其中，当待使用的流体和使用后回收的流体是同一种流体时，可以根据具体使用需求，设计为混合存放或独立存放。根据流体容器100的设计需要，可设计或选择使用一体式多孔位试剂盒、分体式的多孔位试剂盒、多个试剂瓶组成的试剂瓶组或多个试管组成的试管组等多种形式的容器或容器组合。文中的“原有流体”表示残留于管路中需要被清除的流体，该流体可根据使用需要进行回收或进行排放。
流体选择模块500可连通于流体管道1、第一废料排放管道2、公共管道7。流体选择模块500主要的功能是管道切换，在运输流体的时候，使需要运输的流体所对应流体管道1与公共管道7连通，或者是在需要清洗公共管道7的时 候，使公共管道7与第一废料排放管道2连通。根据流体选择模块500的设计需要，可使用选择阀，选择阀属于旋转剪切阀。在设计时需要根据运输的流体种类确定选择阀的位置数，例如常见的有六位七通选择阀，十位十一通选择阀，24位25通选择阀。此外，还可以使用多个二位三通电磁阀和二位二通电磁阀以及对应的基板组成的阀组，从而实现上述功能。此外，使用自动化移液系统也可以实现上述功能。
驱动模块200连通有第一动力管道8、第二动力管道9、第一准备管道3、第二准备管道4。其中，第二准备管道4不是必须存在的设计，是根据驱动模块200驱动流体运动的原理所决定的。驱动模块200主要的功能是驱动流体的流动，因此流体系统中可以形成的所有的流动路径都应该与驱动模块200连通。驱动模块200通过第一动力管道8和第二动力管道9提供驱动力，因此，可以同时维持两个不同的流动路径中的流体运输。当驱动模块200向外提供正压驱动力时，这是一个向外推送流体的过程，驱动模块200需要连接第一准备管道3，从流体容器100中抽吸起填充作用的流体，补充向外推送的体积。而当驱动模块200向外提供负压驱动力时，这是一个向内抽吸流体的过程，对于一些驱动方式，例如，隔膜泵，齿轮泵，驱动模块200需要连接第二准备管道4，向废料容器700中排放流体，留出向内抽吸的体积，而对于另一些驱动方式，例如注射器，则并不是一定要连接到第二准备管道4，此类驱动方式可以先将需要抽吸的流体吸入注射器，待转换模块400将驱动模块200连接到其它管道时再向外推出。此外，当流动池模块300通过旁路管道13连接到驱动模块200时，为了将旁路管道13中的流体运输到废料容器700，也需要通过第二准备管道4，使驱动模块200连接到废料容器700。
根据驱动模块200的设计需要，可使用注射泵，柱塞泵，隔膜泵，齿轮泵等常见的方式驱动流体，还可以使用压缩空气，重力溢流等特殊方式驱动流体。这里需要说明的是，每种方式都需要为所需连接的管道配置足够多孔位的阀头，用于管道的连接和切换。通常注射泵会提供可选择的阀头，而有些种类的泵则需要额外使用自制的阀组作为阀头。
路径切换模块600可连通于分流管道10、流体回收管道5、第二废料排放管道6。路径切换模块600主要的功能是管道切换，在需要回收流体的时候，使分流管道10与流体回收管道5连通，或者是在需要排放废液的时候，使分流管道10与第二废料排放管道6连通。根据路径切换模块600的设计需要，可使用选择阀，主要根据需要回收的流体种类确定选择阀的位置数，例如常见的六位七通选择阀，十位十一通选择阀，二十四位二十五通选择阀。还可以使用多个二位三通电磁阀和二位二通电磁阀以及对应的基板组成的阀组实现上述功能。此外，使用自动化移液系统也可以实现上述功能。
流动池模块300具有流动池入口A和流动池出口B，连通有流动池入口管道11、流动池出口管道12、旁路管道13。流动池模块300的主要功能是使新流体从流动池入口管道11流入，并使原有流体从流动池出口管道12流出，流体将会在流动池模块300的流动池中进行生物或化学反应。流动池内的生物或化学反应的设计不是本申请的内容。流动池模块300有时会根据设计需要增加旁路管道13，使一些流体可以不进入流动池而直接排出，因此，旁路管道13也不是必须存在的。
废料容器700可连通于第二废料排放管道6、第二准备管道4、流体回收管道5。废料容器700主要的功能是存放使用后废弃流体，可以根据具体实施的需求，设计为混合存放或独立存放。根据废料容器700的设计需要，可设计或选择使用一体式多孔位废料盒、废料桶等多种形式的容器或容器组合。

公共管道7，连接流体选择模块500和转换模块400管道。本实施例中，公共管道7连接到接口b。公共管道7设置为将流体从流体选择模块500运输到转换模块400，也可以反向运输。由于公共管道7为流体容器100中的所有流体共同使用，因此在每次运输流体前需要做清洗。
第一动力管道8，连接驱动模块200和转换模块400的管道。本实施例中，第一动力管道8连接到接口a。第一动力管道8设置为将流体从驱动模块200运输到转换模块400，也可以反向运输。

流动池出口管道12，连接流动池模块300和转换模块400的管道。本实施例中，流动池出口管道12连接到接口d。流动池出口管道12设置为将流体从流动池模块300运输到转换模块400。流动池出口管道12的数量取决于流动池的通道数。
旁路管道13，连接流动池模块300和驱动模块200的管道。流动池模块内的流体能够进入旁路管道13暂存，进而能够从旁路管道13运输到驱动模块200，再通过第二准备管道4排放到废料容器700。旁路管道13不是必须设置的管道，取决于本申请的实施需求。
分流管道10，连接路径切换模块600和转换模块400的接口f的管道。本实施例中，分流管道10连接到接口f。分流管道10设置为将流体从转换模块400运输到路径切换模块600。分流管道10的数量取决于流动池的通道数。
第一废料排放管道2，连接流体选择模块500和废料容器700的管道。第一废料排放管道2设置为将流体从流体选择模块500运输到废料容器700。
第二废料排放管道6，连接路径切换模块600和废料容器700的管道。第二废料排放管道6设置为将流体从路径切换模块600运输到废料容器700。
第一准备管道3，连接驱动模块200和流体容器100的管道。第一准备管道3设置为将流体从驱动模块200运输到流体容器100，也可以反向运输，即流体容器100中的流体可以通过第一准备管道3进入驱动模块200。第一准备管道3的数量取决于驱动模块200的设计。
第二准备管道4，连接驱动模块200和废料容器700的管道。第二准备管道4设置为将流体从驱动模块200运输到废料容器700，也可以反向运输。第二准备管道4的数量取决于驱动模块200的设计，以及是否有旁路管道13。
流体回收管道5，连接路径切换模块600和流体容器100的管道。流体回收管道5设置为将流体回收管道5中回收的流体运输到流体容器100。流体回收管道5的数量取决于流体容器100的方案，每一种需要回收的流体都需要有个流体回收管道5与流体容器100中的孔位一一对应。而当路径切换模块600使用自动化移液系统时，流体回收管道5可以只有一个，需要连通采样针，此时流体回收管道5为流体容器100中的所有需要回收的流体共同使用。
以下对本实施例中的多条流动路径进行详细说明：
流体流动路径包括“路径1-1”，该路径存在于转换模块400的第一状态。该路径1-1中，流体流动的驱动力来自于驱动模块200通过第一动力管道8提供的负压。可选地，流体选择模块500通过流体管道1和流体容器100连通，流 体选择模块500通过公共管道7和接口b连通，流体选择模块500设置为对流体容器100内的多种流体进行选择性输送。示例性地，流体从流体容器100出发，依次通过流体管道1、流体选择模块500、公共管道7、转换模块400的接口b、转换模块400的接口a、第一动力管道8，到达驱动模块200。该路径1-1可以用于将流体从流体容器100向流动池模块300运输前的准备，使需要运输的流体预先填充于公共管道7。在实际设计中，通过该路径1-1可以使流体容器100中的流体预先完成在流体选择模块500和公共管道7中的替换，使原有流体进入第一动力管道8中暂存。在一些实施例中，流体还可以从驱动模块200通过第二准备管道4到达废料容器700进行排放。
在一实施例中，流体流动路径还包括“路径2-1”，该路径存在于转换模块400的第二状态。该路径2-1中，流体流动的驱动力来自于驱动模块200通过旁路管道13提供的负压。流动池模块300通过旁路管道13和驱动模块200连通，驱动模块200通过第二准备管道4和废料容器700连通，流动池模块300内的流体能够依次经旁路管道13、驱动模块200和第二准备管道4流向废料容器700。示例性地，流体从流体容器100出发，依次通过流体管道1、流体选择模块500、公共管道7、转换模块400的接口b、转换模块400的接口c、流动池入口管道11、流动池模块300、旁路管道13、驱动模块200和第二准备管道4到达废料管道。在实际设计中，旁路管道13可以任意设计，既可以设置在流动池的入口之前，也可以设置在流动池的出口之后，也可以不设置旁路管道13。若旁路管道13设置在流动池的入口之前，则通过该路径2-1可以使流体容器100中的流体完成在流动池入口管道11中的替换，使流动池入口管道11中的原有流体通过旁路管道13、驱动模块200和第二准备管道4进入废料容器700。若旁路管道13设置在流动池的入口之后，则通过该路径2-1可以使流动池中的流体通过旁路管道13、驱动模块200和第二准备管道4进入废料容器700。
在一实施例中，流体流动路径还包括“路径2-2”，该路径存在于转换模块400的第二状态，驱动力来自于驱动模块200通过第二动力管道9提供的负压。可选地，转换模块400的接口d通过流动池出口管道12和流动池模块300连通，接口e通过第二动力管道9和驱动模块200连通，接口d能够和接口e连通，在驱动模块200的作用下，流动池模块300内的原有流体能够依次经流动池出口管道12、接口d和接口e至第二动力管道9储存。可选地，驱动模块200通过第二准备管道4连通于废料容器700，第二动力管道9内的原有流体能够在驱动模块200的作用下，经第二准备管道4流向废料容器700。示例性地，流体从流体容器100出发，依次通过流体管道1、流体选择模块500、公共管道7、转换模块400的接口b、转换模块400的接口c、流动池入口管道11、流动池模块300、流动池出口管道12、转换模块400的接口d、转换模块400的接口e和第 二动力管道9到达驱动模块200。在一些实施例中，流体还可以从驱动模块200通过第二准备管道4到达废料容器700进行排放。在实际设计中，通过该路径2-2可以使流体容器100中的流体完成在流动池模块300的流动池中的替换，使流动池中的原有流体进入第二动力管道9暂存。
在一实施例中，流体容器100通过第一准备管道3和驱动模块200连通，接口a能够连通于废料容器700或流体容器100，流体容器100内的流体能够在驱动模块200的作用下，依次经第一准备管道3、第一动力管道8、接口a流向废料容器700，以清除第一动力管道8中的原有流体，或依次经第一准备管道3、第一动力管道8、接口a流向流体容器100，以回收第一动力管道8中的原有流体。因此，流体流动路径还包括“路径2-3”和“路径2-4”。
“路径2-3”存在于转换模块400的第二状态，该路径中，流体流动的驱动力来自于驱动模块200通过第一动力管道8提供的正压。在本实施例中，流体从流体容器100出发，依次通过第一准备管道3、驱动模块200、第一动力管道8、转换模块400的接口a、转换模块400的接口f、分流管道10、路径切换模块600、第二废料排放管道6，到达废料容器700。该路径2-3可以用于流体容器100中的流体对第一动力管道8、转换模块400、分流管道10和路径切换模块600的遍历。该路径2-3在实际应用过程中，可将清洗剂输送至第一动力管道8、转换模块400、分流管道10和路径切换模块600，进行管路和模块的清洗。
“路径2-4”存在于转换模块400的第二状态，该路径中，流体流动的驱动力来自于驱动模块200通过第一动力管道8提供的正压。流体从流体容器100出发，依次通过第一准备管道3、驱动模块200、第一动力管道8、转换模块400的接口a、转换模块400的接口f、分流管道10、路径切换模块600、流体回收管道5，到达流体容器100。该路径2-4可以用于流体容器100中的流体对第一动力管道8、转换模块400、分流管道10、路径切换模块600和流体回收管道5的遍历。在实际设计中，可以使用清洗剂对第一动力管道8、转换模块400、分流管道10、路径切换模块600和流体回收管道5进行清洗。这里需要注意的是，这个路径需要将流体运输到流体容器100，如果运输的流体是清洗剂，则会造成对流体容器100的污染，因此运输清洗剂只能用于完成工作后的自动清洗流程。
在一实施例中，公共管道7能够连通于废料容器700或流体容器100，流体容器100中的流体能够在驱动模块200的作用下，依次经第一准备管道3、第一动力管道8、公共管道7进入废料容器700，以将公共管道7中的原有流体清除，或依次经第一准备管道3、第一动力管道8、公共管道7进入流体容器100，以将公共管道7中的原有流体回收。可选地，流体选择模块500和公共管道7连通，废料容器700通过第一废料排放管道2和流体选择模块500连通，流体容 器100通过流体管道1和流体选择模块500连通。因此，流体流动路径还包括“路径1-2”和“路径1-3”。
“路径1-2”存在于转换模块400的第一状态，流体流动的驱动力来自于驱动模块200通过第一动力管道8提供的正压。示例性地，流体从流体容器100出发，依次通过第一准备管道3、驱动模块200、第一动力管道8、接口a、接口b、公共管道7、流体选择模块500、第一废料排放管道2，到达废料容器700。该路径实现了流体容器100中的流体对转换模块400、公共管道7和流体选择模块500的遍历。在实际应用中，可利用“路径1-2”将清洗剂输送至转换模块400、公共管道7和流体选择模块500进行管路和模块的清洗。
“路径1-3”存在于转换模块400的第一状态，流体流动的驱动力来自于驱动模块200通过第一动力管道8提供的正压。示例性地，流体从流体容器100出发，依次通过第一准备管道3、驱动模块200、第一动力管道8、转换模块400的接口a、转换模块400的接口b、公共管道7、流体选择模块500、流体管道1，到达流体容器100。该路径实现了流体容器100中的流体对转换模块400、公共管道7、流体选择模块500和流体管道1的遍历。在实际应用中，可利用“路径1-3”将清洗剂输送至转换模块400、公共管道7、流体选择模块500和流体管道1进行管路和模块的清洗。这里需要注意的是，这个路径需要将流体运输到流体容器100，如果运输的流体是清洗剂，则会造成对流体容器100的污染，因此运输清洗剂只能用于完成工作后的自动清洗流程。
在一实施例中，接口e能够连通于接口f，接口f连通有分流管道10，分流管道10连通于废料容器700或流体容器100，储存于第二动力管道9中的原有流体，能够依次经接口e、接口f和分流管道10流向废料容器700或流体容器100。因此，流体流动路径还包括“路径1-4”和“路径1-5”。
“路径1-4”存在于转换模块400的第一状态，驱动力来自于驱动模块200通过第二动力管道9提供的正压。可选地，路径切换模块600通过分流管道10连通于接口f，路径切换模块600通过第二废料排放管道6连通于废料容器700，储存于第二动力管道9中的原有流体，能够依次经接口e、接口f、分流管道10、路径切换模块600和第二废料排放管道6流向废料容器700，以将原有流体排放。示例性地，流体从流体容器100出发，依次通过第一准备管道3、驱动模块200、第二动力管道9、转换模块400的接口e、转换模块400的接口f、分流管道10、路径切换模块600、第二废料排放管道6，到达废料容器700。该路径可以用于流体容器100中的流体对转换模块400、分流管道10和路径切换模块600的遍历。“路径1-4”实现了利用起填充作用的流体将第二动力管道9中暂存的不可回收的原有流体推送到废料容器700，或使用清洗剂对转换模块400、分流管道 10和路径切换模块600进行清洗。
“路径1-5”存在于转换模块400的第一状态，驱动力来自于驱动模块200通过第二动力管道9提供的正压。可选地，路径切换模块600通过流体回收管道5连通于流体容器100，储存于第二动力管道9中的原有流体，能够依次经接口e、接口f、分流管道10、路径切换模块600和流体回收管道5流向流体容器100，以将原有流体回收。示例性地，流体从流体容器100出发，依次通过第一准备管道3、驱动模块200、第二动力管道9、转换模块400的接口e、转换模块400的接口f、分流管道10、路径切换模块600、流体回收管道5，到达流体容器100。该路径可以用于将暂存在第二动力管道9中的流体回收到流体容器100。在实际设计中，可以使用起填充作用的流体将第二动力管道9中暂存的可回收的原有流体推送到流体容器100，也可以使用清洗剂对转换模块400、分流管道10、路径切换模块600和流体回收管道5进行清洗。这里需要注意的是，这个路径能够将流体运输到流体容器100，如果运输的流体是清洗剂，则会造成对流体容器100的污染，因此运输清洗剂只能用于完成工作后的自动清洗流程。
根据上述对路径的分析，可以看出，在本实施例中，当转换模块400处于第一状态时，“路径1-1”、“路径1-2”和“路径1-3”是互斥的，而“路径1-4”和“路径1-5”是互斥的。“路径1-1”、“路径1-2”和“路径1-3”的其中之一，可以与“路径1-4”和“路径1-5”的其中之一同时执行而不互斥。当转换模块400处于第二状态时，“路径2-2”和“路径2-1”是互斥的，而“路径2-3”和“路径2-4”是互斥的。“路径2-2”和“路径2-1”的其中之一，可以与“路径2-3”和“路径2-4”的其中之一同时执行而不互斥。
图2为本实施例提供的该流体系统的一种工作逻辑的示意图，使用该工作逻辑可以实现对多种流体的运输，同时还能完成对可再利用的流体的回收，以及对流体路径的实时清洗。在其他实施例中，可根据使用需要对工作逻辑进行合理调整，在此不对所有方案进行一一列举。本实施所提供的工作逻辑分为3个步骤(以下的“试剂”表示发生反应所需的一种或几种流体)：
步骤1，将转换模块400设置为第一状态，使用“路径1-1”将第1种试剂从流体容器100中取出，并使该试剂完成在公共管道7中的替换。
步骤2，将转换模块400设置为第二状态，先使用“路径2-1”将第1种试剂从公共管道7继续运输，并使该试剂完成在流动池入口管道11中的替换。然后使用“路径2-2”，使该试剂完成在流动池中的替换。在使用“路径2-1”和“路径2-2”时，同时使用“路径2-3”，完成对分流管道10和路径切换模块600的清洗和排空。
步骤3，将转换模块400设置为第一状态，先使用“路径1-2”将切换模块、 公共管道7和流体选择模块500中的第1种试剂或第1种试剂的残留清洗并排放到废料容器700，然后使用“路径1-1”将第2种试剂从流体容器100中取出，并使该试剂完成在公共管道7中的替换。在使用“路径1-2”和“路径1-1”时，同时选择是否对第1种试剂进行回收，如果不对第1种试剂进行回收，则只使用“路径1-4”将不回收的废料排放到废料容器700，如果对第1种试剂进行回收，则先使用“路径1-5”，完成对第1种试剂的回收，再使用“路径1-4”，将不回收的废料排放到废料容器700。
