Description

废液处理装置、方法以及样本分析仪 技术领域
本申请涉及样本检测及分析技术领域，尤其涉及一种废液处理装置、方法以及样本分析仪。
背景技术
在样本分析仪(例如血液细胞分析仪)的整个检测分析过程中，各个检测通道、清洗通道等都会产生一定量的废液，产生的废液通过废液管道进行收集并排放到机外。由于目前的样本分析仪的各个检测通道通常都是并行检测的，测试速度非常快，在提高了测试速度后，废液处理成了限速步骤，因此，提高废液处理速度至关重要。目前常用的废液收集和排放方式有以下方案：
方案一，如图1所示的废液处理装置101，直接利用废液泵11收集各个废液管道1、2、3…的废液并排放到机外。此方案结构简单，可实现单泵排放多通道废液，但存在以下缺点：1、由于废液泵11流量有限，废液管道1、2、3…无法并行排废；此外，若并行排液会出现某一废液管道提前排空而导致其他废液管道排液不畅的情况，因此只能支持单一通道排液，效率较低。2、废液需要流经废液泵11，废液中存在的碎屑容易使废液泵11中的单向阀失效，从而损坏废液泵11。
方案二，如图2所示的废液处理装置102，利用带压力切换的废液缓存装置，例如废液池13来进行机内废液的收集和排放。废液池13通过控制阀12与供压装置(图未示，一般为大流量气泵)连接，当将废液池13切换为负压状态时，废液池13收集各条废液管道1～8的废液；当将废液池13切换为正压状态时，废液池13将废液排到机外。此方案虽然可实现多个通道同时收集废液，但有以下缺点：1、废液从产生到排到机外需经过两个步骤：收集废液管道的废液和废液池13排空。在废液池13排空的同时，无法收集废液管道1～8里的废液。假设收集废液管道1～8里的废液需要的时间为T1，废液池13排空的时间为T2，将从收集废液到排到机外作为一个周期的时间T，则T＝T1+T2，在时间T2内无法收集废液，将整个废液处理周期加长了T2。在血液细胞分析仪中，关键路径T的长短影响仪器的检测速度。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图3，为本申请一实施方式的一种废液处理装置200的原理框图。所述废液处理装置200用于处理多条废液管道(图未示)中的废液。应说明的是，本申请所提及的“处理”废液包括收集及排放废液。在本实施方式中，所述废液处理装置200包括至少两个废液池21、控制装置22以及供压装置30。其中，每一所述废液池21与至少一条所述废液管道连通。
在另一实施方式中，可将所述多条废液管道预先分成至少两组废液管道，每一所述废液池21与一组所述废液管道连通。其中，每组所述废液管道包括一条或多条废液管道。
在本实施方式中，所述供压装置30分别与所述至少两个废液池21连接，用于为各个废液池21提供气压。所述废液池21用于在其内部处于负压状态时收集所连接的废液管道内的废液，以及在其内部处于正压状态时排放收集到的废液。在本实施方式中，所述废液池21内部的常态为负压状态，用于收集及储存废液。
所述控制装置22用于根据各个废液池21对应的预设气压时序控制所述供压装置30为各个废液池21提供的气压，使得在废液处理过程中的任何时刻均有至少一个废液池21的内部处于负压状态以收集废液。通常，废液的收集过程比较缓慢，排废液的过程比较快。因此，保证废液的处理过程中能够一直收集废液就能大大提升废液的处理速度。此外，保证废液处理过程中的任何时刻均有至少一个废液池21收集废液亦能保证在废液的处理过程中，可以并行废液收集和排放过程，省去了串行执行收集和排放过程中的等待时间。
可以理解的是，所述预设的气压时序可以预先写入控制程序中，还可以是通过人工进行设定的气压时序。
此外，所述控制装置22还可以用于控制所述供压装置30分别为各个废液池21交替地提供负压和正压，使各个废液池21的内部交替地处于负压状态和正压状态以交替地收集和排放 废液，并使所述废液处理装置200在废液处理过程中能够同时地进行废液的收集和排放。例如，所述控制装置22可通过控制所述供压装置30为各个废液池21提供的气压，使得在废液处理过程中的任何时刻均有至少一个废液池21的内部处于负压状态以收集废液，以及有至少一个废液池21的内部处于正压状态以排放废液，从而在任意时刻都能同时地收集和排放废液。亦或者，所述控制装置22可通过控制所述供压装置30为各个废液池21提供的气压，使得在废液处理过程中的任何时刻均有至少一个废液池21的内部处于正压状态以排放废液，从而使得废液处理装置能够在某一时刻同时收集和排放废液，以提升废液处理效率。
具体地，在本实施方式中，所述预设气压时序包括负压时段和正压时段。所述控制装置22用于在各个废液池21对应的负压时段期间控制所述供压装置30分别为各个废液池21提供负压，以及在各个废液池21对应的正压时段期间控制所述供压装置30分别为各个废液池21提供正压。
可以理解，在一种实施方式中，所述至少两个废液池21对应的负压时段可以相互不交叉，使得在废液处理过程中的任何时刻均只有一个废液池在收集废液。
例如图4所示，以两个废液池A、B为例，两个废液池A、B对应的负压时段相互不交叉，使得在废液处理过程中的任何时刻均只有一个废液池A或B在收集废液。可以理解的是，在其他实施方式中，还可以通过两个废液池A、B对应的正压时段相互不交叉，使得在废液处理过程中的任何时刻均只有一个废液池A或B在排放废液，并使得在废液处理过程中可以同时进行收集废液和排放废液的动作。
可选地，在另一种实施方式中，所述至少两个废液池21对应的负压时段可以部分交叉，使得在废液处理过程中的任何时刻均有一个或多于一个废液池21在收集废液。
例如图5所示，以三个废液池A、B、C为例，三个废液池A、B、C对应的负压时段部分交叉，在废液处理过程中的任何时刻均有至少一个废液池21在收集废液，例如，在时刻t2时只有废液池A在收集废液，在时刻t3时废液池A、B、C同时在收集废液，在时刻t4时废液池B、C同时在收集废液。可以理解的是，在其他实施方式中，还可以通过三个废液池A、B、C对应的正压时段部分交叉，使得废液处理过程中任何时刻均有至少一个废液池在排放废液。可以理解的是，保证废液处理过程中任何时刻均有至少一个废液池21在收集和/或排放废液，使得废液处理装置200在废液处理过程中可以并行执行收集废液和排放废液的动作。
请再次参阅图3，在一种实施方式中，所述供压装置30包括负压源和正压源，其中，所述负压源用于提供负压，所述正压源用于提供负压。在另一种实施方式中，所述供压装置30可通过调节来产生负压和正压。
在废液收集过程中，所述供压装置30可通过气压管道给所述废液池21提供负压，例如，所述供压装置30通过气压管道抽气而使所述废液池21内产生负压，在负压抽吸下能够将废液源产生的废液从废液源的排放口中抽吸到废液管道中，再从废液管道中抽进废液池21中。
在本实施方式中，所述控制装置22包括控制器221以及至少两个控制阀222，每一控制阀222连接于所述供压装置30以及一废液池21之间，所述控制器221与各个控制阀222连接，所述控制器221用于通过控制各个控制阀222的导通状态，以控制所述供压装置30为各个废液池21提供的气压，从而控制各个废液池21内部的压力状态。其中，所述控制器221可为单片机、可编程逻辑控制器(Programmable Logic Controller，简称PLC)或其他控制器。
在本实施方式中，各个控制阀222至少包括负压通道和正压通道，所述控制器221用于交替地导通各个控制阀222的负压通道和正压通道，以控制所述供压装置30为各个废液池21交替地提供负压和正压。
具体地，请参阅图6，为本申请第一实施方式的废液处理装置200的结构示意图。在本实施方式中，以所述废液处理装置200包括两个废液池21-1和21-2、两个控制阀222-1和222-2、以及8条废液管道1～8，且两个废液池21-1和21-2对应的负压时段相互不交叉为例进行说明。其中，所述废液池21-1分别与废液管道1～4连接，所废液池21-2分别与废液管道5～8连接，所述废液池21-1和21-2的底部分别设置有排液口2111。
一种具体的实施方式中，在废液处理过程中，当导通所述控制阀222-1的负压通道时，所述废液池21-1与所述供压装置30的负压气口连通并与正压气口断开连接，所述废液池21-1 内为负压状态，该压力使得所述废液池21-1能够收集所述废液管道1～4内的废液。与此同时，所述控制阀222-2的正压通道导通，所述废液池21-2与所述供压装置30的负压气口断开连接并与正压气口连通，所述废液池21-2内为正压状态，该压力将所述废液池21-2内的废液通过所述废液池21-2的排液口2111排放到机外。
同样地，当将所述控制阀222-1的导通位置切换到正压通道时，所述废液池21-1与所述供压装置30的负压气口断开连接并与正压气口连通，所述废液池21-1内切换正压状态，该压力将所述废液池21-1内的废液通过所述废液池21-1的排液口2111排放到机外。与此同时，所述控制阀222-2的导通位置切换到负压通道，所述废液池21-2与所述供压装置30的负压气口连通并与正压气口断开连接，所述废液池21-2内为负压状态，该压力使得所述废液池21-2能够收集所述废液管道5～8内的废液。
可以理解，在其他实施方式中，所述废液池21的数量不限于两个，所述控制阀222的数量不限于两个，所述废液管道的数量不限于8条。
本申请的废液处理装置200通过控制所述供压装置30交替地为各个废液池21提供负压和正压，能够快速地收集和排放废液。
可以理解，在其他实施方式中，在不考虑排放废液的速度的情况下，所述供压装置30也可只给所述废液池21提供负压，以控制所述废液池21收集废液。在释放所述废液池21中的负压时，所述废液池21中的废液可以通过自身的重力从废液池21的排液口2111中排出。
本申请的废液处理装置200通过使用至少两个废液池21，并给至少两个废液池合理地设置预设气压时序，再控制所述废液池21按预设时序交替地处于负压状态和正压状态，可以实现各个废液池并行地收集和排放多个废液管道中的废液，同时确保在废液处理过程中的任何时刻均有至少一个废液池在收集废液，从而能够有效地缩短废液处理周期，为使用所述废液处理装置200的检测装置(例如样本分析仪)提高检测速度提供了支持。此外，本申请的废液处理装置200结构简单且生产成本低，有利于所述废液处理装置200广泛地应用到各种检测装置中。
在本实施方式中，所述多条废液管道的一端分别与多个废液源的排放口一一连通，另一端根据其连接的废液源的排废时序与相应的废液池21连通，各个废液池21对应的负压时段与其所连接的废液管道对应的废液源的排废时序对应。例如，由于每个废液源均有相应的排废时间，且各个废液源的排废时间有长有短，可以相同或不同，可根据各个废液源的排废时间来设定所述废液池21的负压时段，并根据各个废液源的排废时间来将与各个废液源连通的废液导管合理地分配到相应的废液池中，使废液池的负压时段与相应的废液源的排废时间对应，从而可以尽可能地控制废液池在废液源排废期间进行废液的收集，并在废液源暂停或停止排废期间排放收集到的废液。
在一种实施方式中，各条废液管道的另一端根据其连接的废液源的排废时序与一个相应的废液池21连接。例如图6所示，各条废液管道1～4的另一端分别与所述废液池21-1连接，各条废液管道5～8的另一端分别与所述废液池21-2连接。
在另一实施方式中，所述多条废液管道中的部分废液管道的另一端根据其连接的废液源的排废时序与一个以上的废液池21连接，且所述一个以上的废液池21对应的负压时段之和与其所连接的相同的废液管道对应的废液源的排废时序对应。例如图7所示，在废液处理装置201中，若废液管道5所连接的废液源的排废时间较长，废液管道5的另一端可通过连接件25(例如三通头)同时与所述废液池21-1和21-2连接，所述废液池21-1和21-2对应的负压时段之和与废液管道5对应的废液源的排废时序对应，从而有利于废液管道5中的废液的收集和排放，并缩短废液处理周期。
本申请的废液处理装置200(201)通过设置至少两个废液池21，并配合预设气压时序的安排，可以及时地排走检测过程中产生的废液，有利于所述检测装置提高检测速度。
由于所述检测装置在检测过程中所使用的有机、无机以及生化试剂、溶剂的种类和数量繁多，因此产生和排出的废液成分也越来越复杂多样，多种废液进入同一废液池中混合可能会发生化学反应而产生污垢，导致废液池在长期使用后累积污垢，增加维护难度。
在本实施方式中，所述多条废液管道的另一端可根据其连接的废液源排放的废液的化学 性质与相应的废液池21连通，使能够发生化学反应并产生污垢的废液分开排放到不同的废液池21。
在另一实施方式中，可将所述多条废液管道预先分成至少两组废液管道，且每一组废液管道所连接的废液源排放的废液混合后相互不发生化学反应而产生污垢，每一所述废液池21与一组所述废液管道连通。
如此即可针对不同化学性质的废液进行分类收集，避免不同化学性质的废液混合后可能发生的意外和事故，也能减少废液混合后产生的污垢对所述废液池21的污染，以降低所述废液池21的维护难度和维护成本。
在本实施方式中，所述废液处理装置200(201)还包括设置于各个废液池21内部的液位传感器215(如图8所示)，所述控制器221还与所述液位传感器215连接。其中，所述液位传感器215用于感测其所在的废液池21内部的液位高度。
在本实施方式中，所述液位传感器215采用浮子传感器。其中，所述浮子传感器通过浮子位置来检测液位，当液面上升到浮子的位置时，由于浮子比重比检测液体小，浮子被液体托起上升。当液面下降到浮子的位置之下时，浮子悬挂在废液池内。可以理解，所述浮子传感器可对应浮子的不同状态来产生不同的触发信号，以报告不同的液位高度。
在其他实施方式中，所述液位传感器可采用电极传感器。其中，所述电极传感器通过判断两根电极是否导通来检测液位，当液面上升到电极的位置使两根电极均与液体接触时，电极间导通。当液面下降到电极的位置之下时，电极断开连接。可以理解，所述电极传感器可对应电极的导通和断开状态来产生不同的触发信号，以报告不同的液位高度。
为了避免所述废液池21内的废液量过高而进入通气口2122(如图8所示)而产生其他的安全事故，在一种实施方式中，所述控制器221还用于在各个废液池21对应的负压时段期间，根据各个废液池21内部的液位传感器215感测到的液位数据来控制所述供压装置30为各个废液池21提供负压的时长，从而控制各个废液池21内的废液量。
具体地，所述控制器221用于在所述液位传感器215感测到相应的废液池21内的液位高度高于第一预设高度时，在相应的废液池21对应的负压时段期间控制所述供压装置30暂停为相应的废液池21提供负压，使相应的废液池21暂停收集废液，其中，所述第一预设高度可设为防止废液进入所述通气口2122的安全高度。在其他实施方式中，所述第一预设高度也可设为防止废液溢出所述废液池21的安全高度。在其他实施方式中，所述控制器221还可在液位高度高于所述第一预设高度时，在相应的废液池21对应的负压时段期间控制所述供压装置30为相应的废液池21提供正压，使相应的废液池21排出废液。
其中，所述控制器221可与所述供压装置30连接，所述控制器221可通过关闭所述供压装置30的负压气口来控制所述供压装置30暂停为相应的废液池21提供负压。可选的，所述控制器221还可通过断开相应的控制阀222的负压通道来控制所述供压装置30暂停为相应的废液池21提供负压，例如，所述控制阀222还可包括封闭通道，所述控制器221可通过将相应的控制阀222的导通的负压通道切换到所述封闭通道，来使所述供压装置30与相应的废液池21断开连接，从而控制所述供压装置30暂停为相应的废液池21提供负压。
可以理解，为了减少***耗气量，所述废液池21可以不进行每周期的正压排液，或者可以根据实际情况缩短正压排液的时间，通过把所述废液池21设计得足够大，使所述废液池21容纳连续多次收集的废液之后，再进行正压排液。
在一种实施方式中，所述控制器221还用于在各个废液池21对应的正压时段期间，根据各个废液池21内部的液位传感器215感测到的液位数据来控制所述供压装置30为各个废液池21提供正压的时长，从而控制各个废液池21内的废液量。
具体地，所述控制器221用于在所述液位传感器215感测到相应的废液池21内的液位高度低于第二预设高度时，在相应的废液池21对应的正压时段期间控制所述供压装置30暂停为相应的废液池21提供正压，使相应的废液池21暂停排液。其中，所述第二预设高度可设为高于所述排液口2111的安全高度，以确保所述废液池21内储存有一定量的废液，并防止所述废液池21的排液口2111与大气相通而造成不必要的***耗气量。可以理解，所述排液口2111的位置可以设于所述废液池21的底部的最低处。
在其他实施方式中，所述控制器221还可在液位高度低于所述第二预设高度时，在相应的废液池21对应的正压时段期间控制所述供压装置30为相应的废液池21提供负压，以继续收集废液。
其中，所述控制器221可与所述供压装置30连接，所述控制器221可通过关闭所述供压装置30的正压气口来控制所述供压装置30暂停为相应的废液池21提供正压。可选的，所述控制器221还可通过断开相应的控制阀222的正压通道来控制所述供压装置30暂停为相应的废液池21提供正压，例如，所述控制阀222还可包括封闭通道，所述控制器221可通过将相应的控制阀222的导通的正压通道切换到所述封闭通道，来使所述供压装置30与相应的废液池21断开连接，从而控制所述供压装置30暂停为相应的废液池21提供正压。
在其他实施方式中，所述废液处理装置200(201)还可包括与所述废液池21的排液口2111连接的控制开关，所述控制器221用于在所述废液池21内部处于负压状态时断开所述控制开关，以防止所述废液池21的排液口2111在收集废液期间与大气相通而影响废液的收集。
在本实施方式中，所述废液处理装置200(201)还包括与所述废液池21的排液口2111连接的排废管23，所述排废管23用于将与其连接的废液池21内的废液处理到机外。
在一种实施方式中，所述废液处理装置200(201)包括一条排废管23，例如图6、7所示，所述排废管23通过连接件24(例如三通头)与各个废液池21的排液口2111连接，所述排废管23用于排放各个废液池内的废液。
在另一种实施方式中，所述废液处理装置200(201)包括多条排废管23，每一所述排废管23与至少一个废液池21的排液口2111连接，所述排废管23用于排放与其连接的废液池内的废液。通过采用多条排废管23，可将各个废液池21收集到的废液分开排放，可避免或减少各个废液池21内的废液混合反应后产生污垢而对环境造成污染。
本申请还提供一种用于处理废液的废液池，请参阅图8，为本申请一实施方式的一种废液池21的内部结构示意图。所述废液池21包括本体211以及设置于所述本体211内部的收容腔217，所述收容腔217用于储存废液。

其中，所述通气口2122的数量可以为一个，供压装置的正压气口和负压气口可通过同一个控制阀与所述通气口2122连接，通过控制所述控制阀的导通位置可实现所述废液池内正压与负压的切换控制。当然，所述通气口2122的数量也可以为两个，所述供压装置的正压气口和负压气口分别通过控制阀与两个通气口2122连接，通过分别控制两个控制阀的导通状态可实现所述废液池内正压与负压的切换控制。
在一种实施方式中，如图8所示，所述本体211为一端开口另一端封闭的腔体，所述废液池21还包括盖体212，所述盖体212用于封闭所述本体211的开口。所述本体211和所述盖体212的形状和大小可以根据要求具体设计，在这里不做具体限定。
在所述一种实施方式中，所述若干个进液口2121和所述通气口2122均设置于所述盖体212上，所述排液口2111设置于所述本体211的底壁。
在其他实施方式中，所述若干个进液口2121和所述通气口2122可均设置于所述本体211的侧壁上部，或者，所述本体211的侧壁上部和所述盖体212上均设置有所述若干个进液口2121和所述通气口2122。在其他实施方式中，所述排液口2111可设置于所述本体211的侧壁，或者，所述本体211的底壁和所述本体211的侧壁均设置有所述排液口2111。
在另一实施方式中，所述本体211为封闭的腔体。可以理解，在所述另一种实施方式中，所述盖体212可以省略。在所述另一种实施方式中，所述本体211的顶壁和/或所述本体211的侧壁上部设置有所述若干个进液口2121和所述通气口2122。
可以理解，当所述通气口2122设置于所述本体211的侧壁上时，所述通气口2122的位 置应设置得尽量高，如所述通气口2122应尽量靠近所述本体211的顶部。
在本实施方式中，所述废液池21还包括收容于所述收容腔217内的第一挡板2141，所述第一挡板2141位于所述通气口2122与所述排液口2111之间且靠近所述通气口2122设置。可以理解，这里所述的“靠近”是指相对于所述排液口2111的位置而言所述第一挡板2141靠近所述通气口2122，而不是指紧贴所述通气口2122。
在本实施方式中，所述废液池21还包括收容于所述收容腔217内的若干条导流管213，所述若干条导流管213一端的管口分别与所述若干个进液口2121中的部分或全部进液口2121连通以将废液管道中的废液导入导流管，所述若干条导流管213另一端的管口设置于所述第一挡板2141之下。所述若干条导流管213用于将废液导流至所述收容腔217中的第一挡板2141的下方，所述第一挡板2141用于阻止所述收容腔217中的泡沫和/或废液进入所述通气口2122。
可以理解，部分所述进液口2121可以用于连接不含废液的液体管道，例如连接溶血剂的液体管道，为了便于溶血剂进入所述废液池21内部以清洁所述废液池21的收容腔217，应使溶血剂从所述废液池21中尽可能高的部位流入所述收容腔217中，在一种实施方式中，可将连接溶血剂的液体管道的进液口2121设于所述本体211的侧壁并位于所述第一挡板2141之下，这时，所述进液口在所述收容腔217内不需要与导流管213连接。在此种情形下，所述若干条导流管213一端的管口分别与所述若干个进液口2121中的部分进液口2121连接。
在另一实施方式中，可将连接溶血剂的液体管道的进液口2121设于所述第一挡板2141之上，例如设于所述盖体212或所述本体211的顶壁，在所述收容腔217内采用导流管213连接所述进液口2121，并将导流管213的管口设于所述第一挡板2141之下。在此种情形下，所述若干条导流管213一端的管口分别与所述若干个进液口2121中的全部进液口2121连接。
现有技术在废液收集过程中，废液在负压力的作用下，从所述收容腔217上部向底部高速冲击液面，使废液容易产生飞溅。此外，部分含有表面活性剂多的试剂，如溶血剂容易在收容腔217中产生大量泡沫，且泡沫堆积在液面上方。当废液池21内收集的废液逐渐增多而使液面上升时，这些飞溅的废液以及泡沫可能被吸入供压装置。另，由于所述废液池21内采用负压收集废液，在负压抽吸过程中，所述收容腔217中的泡沫容易经由所述通气口2122被直接吸入到导气管中，可能对供压装置中的气动元件(例如负压泵、负压阀、启动调压阀等)造成破坏。本申请的废液池21通过在收容腔217中设置靠近所述通气口2122的第一挡板2141，以及采用导流管213将从进液口2121流出的液体导流至所述第一挡板2141之下，从而在废液池21内部将气液接口隔离，可减少或避免了泡沫及/或废液进入导气管中的可能性，并能够保护供压装置中的气动元件免遭破坏，有效地解决了检测装置提速后带来的废液处理的可靠性问题。
在本实施方式中，所述废液池21还包括第二挡板2142，所述第二挡板2142收容于所述收容腔217内并位于所述第一挡板2141与所述排液口2111之间，即，所述第一挡板2141位于所述第二挡板2142之上。
在本实施方式中，所述若干条导流管213的数量为多条，多条所述导流管213另一端的管口按照其导流的废液的属性设置于所述第二挡板2142之上和/或之下，以将不同的废液分别导入所述收容腔217内部的不同高度。例如，可将导流不含血液的废液的导流管另一端的管口设置在第二挡板2142之上，以将该废液引流到第二挡板2142之上；将导流含高浓度血的废液的导流管另一端的管口设置于第二挡板2141之下，以将该废液引流到第二挡板2142之下。可以理解的是，此时各条导流管可具有不同的长度，以便将不同废液管道的废液引流到废液池的不同高度部位排出。
在本实施方式中，所述废液池21还包括第三挡板，所述第三挡板收容于所述收容腔217内并位于所述第一挡板2141和所述第二挡板2142之间，其中，所述第三挡板可包括一层或多层挡板。通过设置所述第一、二、三挡板，可根据实际使用情况将导入所述收容腔217的不同液体阻隔在不同的挡板之下。
例如，可将导流溶血剂的导流管另一端的管口设置在第一挡板2141和第三挡板之间，以便于将溶血剂从所述收容腔217中尽可能高的部位引流到所述收容腔217中对所述收容腔217 进行清洗，同时又能避免溶血剂产生的泡沫进入所述通气口2122；可将导流含低浓度血的废液的导流管另一端的管口设置在第三挡板和第二挡板2142之间，以将该废液引流到第二挡板2142之上；将导流含高浓度血的废液的导流管另一端的管口设置于第二挡板2141之下，以将该废液引流到第二挡板2142之下。
在其他实施方式中，所述若干条导流管213另一端的管口也可均设置于所述第二挡板2142的下方。如此，可将所述导流管213的另一端的管口的位置设置得尽可能低，如尽量靠近所述废液池21底部的排液口2111，从而能够将废液导入到废液池21的下部，使废液不会直接冲击液面，在最大程度上减少或避免废液在所述废液池中发生飞溅，同时也减少了泡沫的产生。
在本实施方式中，所述若干条导流管213的另一端从上至下分别依次穿过所述废液池21的一层或多层挡板，使其另一端的管口位于其所穿过的挡板之下，所述废液池21的各层挡板还用于固持穿设于其上的导流管213，以防止所述导流管213在废液收集过程中在所述收容腔217内乱窜而影响废液收集或发生其他安全事故。
在其他实施方式中，所述若干条导流管213的另一端可沿所述收容腔217的内壁向靠近所述收容腔217的底部的方向延伸，使其另一端的管口位于所述第二挡板2142之上和/或之下。
如上所述，现有技术在废液收集过程中，废液在负压力的作用下，从所述收容腔217的上部向底部高速冲击液面，使废液容易产生飞溅，使整个废液池21内壁都会接触到废液，长期使用后，整个废液池21内壁都会有污垢(例如血垢)附着，因此在进行废液池维护时，需使整个废液池充满清洗液，维护难度高，且难以实现机器自维护，往往需要人工定期手动维护，增加维护成本。
在本实施方式中，所述废液池21的各层挡板还用于阻止位于其下方的导流管213管口中流出的废液与位于其之上的所述收容腔217的内壁接触。例如，当将导流溶血剂的导流管另一端的管口设置在第一挡板2141和第三挡板之间时，由于所述第一挡板2141位于所述通气口2122与所述排液口2111之间，即所述通气口2122位于所述第一挡板2141之上，所述第一挡板2141就能尽可能地阻挡溶血剂的液滴与所述第一挡板2141上方的所述本体211的内壁接触，从而可以减少溶血剂产生的泡沫或液滴进入所述通气口2122的可能性。当可将导流含低浓度血的废液的导流管另一端的管口设置在第三挡板和第二挡板2142之间时，所述第三挡板就能阻挡含低浓度血的废液液滴与所述第三挡板上方的所述本体211的内壁接触，以降低废液对所述本体211的内壁的污染。当将导流含高浓度血的废液的导流管另一端的管口设置于第二挡板2141之下时，第二挡板2141就能阻止含高浓度血的废液液滴与所述第二挡板2142上方的所述本体211的内壁接触，以降低废液对所述本体211的内壁的污染。
本申请的废液池21通过在收容腔217内设置挡板，使得废液不会越过挡板而与位于挡板之上的所述本体211的内壁大面积接触，在长时间使用后只有挡板以下的壁面会变脏而需要维护，这样可减少废液池维护时的试剂耗量，且更易维护。
在本实施方式中，所述废液池21还包括连杆216，所述连杆216一端固定于所述收容腔217的顶壁(例如盖体212或所述本体211的顶部)上，另一端向靠近所述收容腔217的底部的方向延伸，所述废液池21的各层挡板分别套设于所述连杆216上。
在本实施方式中，所述废液池21还包括设置于所述收容腔217内部的所述液位传感器215，所述液位传感器215用于感测所述废液池21内部的液位高度。
在本实施方式中，所述液位传感器215设置于所述连杆216上。在其他实施方式中，所述液位传感器215可设置于所述本体211的内壁上或者以其他方式设置于所述收容腔217内。

在本实施方式中，所述废液处理装置200(201)的废液池21通过多条废液管道与所述样本分析仪400的废液源的排放口连通，所述废液池21用于处理与其连通的废液源产生的废液。
在本实施方式中，所述样本分析仪400的废液源可以为加样针清洗池、试剂盘排废液管路、磁分离盘、反应池中的至少一个。可以理解，所述废液源也可以为所述样本分析仪400中的其他需要排液的组件。

例如，通过控制供压装置为各个废液池提供的气压，使得在废液处理过程中的任何时刻均有至少一个废液池的内部处于负压状态以收集废液，以及有至少一个废液池的内部处于正压状态以排放废液，从而在任意时刻都能同时地收集和排放废液。或者，控制供压装置为各个废液池提供的气压，使得在废液处理过程中的任何时刻均有至少一个废液池的内部处于正压状态以排放废液，从而某一时刻能够并行执行收集和排放废液动作，节省串行执行收集和排放废液动作时的等待时间。亦或者，优选的，控制供压装置为各个废液池提供的气压，使得在废液处理过程中的任何时刻均有至少一个废液池的内部处于负压状态以收集废液，从而某一时刻能够并行执行收集和排放废液动作，节省串行执行收集和排放废液动作时的等待时间。
