参见图1,本发明提供了一种化学发光分析仪,该化学发光分析仪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,需要通过试管等容器承载液体样本并置于样本架上才能进行。进一步的液体样本包括但不限于血液样本。使用本发明的化学发光分析仪对血液样本进行检测时,血液样本存储于试管中,并顺序放置在试管架上。本发明的化学发光分析仪的结构简单,操作方便,同时还能减小整机尺寸使得占用空间小,并降低生产成本,进而使得化学发光分析仪易于实现小型化发展,方便操作人员使用。
在本发明中,化学发光分析仪包括样本装载装置01、试剂装载装置02、分注装置03、混匀装置04、样本孵育装置05、磁分离清洗装置06、样本检测装置07以及转运抓杯装置08。样本装载装置01用于承载样本容器。可以理解的是,样本装载装置01中的样本可以通过操作人员手动添加,也可使用自动进样结构自动添加样本。试剂装载装置02用于存储试剂,即试剂装载装置02装载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。分注装置03用于吸排样本与试剂,以实现将样本或试剂转移到反应容器中。混匀装置04用于支撑反应容器,并混合反应容器中的样本与试剂。可以理解的是,空的反应容器被转移到混匀装置04中,分注装置03分别将样本与试剂转移到反应容器中,通过混匀装置04将样本与试剂混合均匀后,将反应容器转移至样本孵育装置05中。样本孵育装置05用于孵育,即对反应容器中的样本与试剂进行孵育操作,磁分离清洗装置06用于分离清洗,即对孵育后反应容器中的样本与试剂进行清洗,以去除杂质。样本检测装置07用于发光检测,即对清洗后反应容器中的样本与试剂进行发光检测,以获取样本的各个参数。反应容器被转移到样本孵育装置05后,样本孵育装置05能够对反应容器中的样本与试剂进行孵育,孵育后的反应容器被转移至磁分离清洗装置06中进行分离清洗,清洗后的反应容器被转移到样本检测装置07中进行发光检测,以得到样本的对应参数。而且,转运抓杯装置08用于转移反应容器,具体的,转运抓杯装置08能够在混匀装置04、样本孵育装置05、磁分离清洗装置06以及样本检测装置07之间转运反应容器。
为了方便对样本与试剂各个阶段名称的理解,此处对样本与试剂各个阶段的名称进行 详述:反应容器中的样本与试剂混合后称为混合物,样本孵育装置05能够对反应容器中的混合物进行孵育操作,使得样本与试剂充分反应,此时,反应容器中的物质为待测物和杂质。其中,混合物是指样本与试剂混合后形成的物质,和样本与试剂的比例、浓度无关,在此都称为混合物。孵育后的混合物在反应容器中以待测物和杂质方式呈现。杂质可为未充分反应的物质,也可以为发生副反应产生的副反应产物,还可以为其他影响样本孵育装置05检测的物质等等,或者为上述至少两种的组合物。磁分离清洗装置06对反应容器中的待测物与杂质进行清洗,以去除反应容器中的杂质,使得反应容器中只存在待测物。样本检测装置07能够检测反应容器中待测物,以得到样本的各项参数。若向分离清洗后反应容器中添加底物,即底物与待测物混合,由于底物不会改变待测物的属性,仅仅增加待测物的发光值,所以底物与待测物混合后仍称为待测物。
样本装载装置01与试剂装载装置02并排设置。样本装载装置01与试剂装载装置02分开设置后,二者之间的结构不在受彼此影响。也就是说,样本装载装置01承载的样本容器数量可以根据使用需求增加,即检测需求大时,放置样本容器就增加;样本检测需求小时,放置样本容器的就减少,这样能够实现样本装载装置01的可扩展性强,满足用户不同的使用需求。在本实施例中,样本装载装置01承载流派样本容器,而样本容器的排数可以根据实际情况进行相应的扩展。相应的,试剂装载装置02承载的试剂容器的数量也可根据使用需求增加,可以采用更换更大容量的试剂装载装置02实现,也可直接在试剂装载装置02的边缘增加试剂容器,只要保证其在分注装置03的运动行程范围内即可。
样本孵育装置05分别与混匀装置04、磁分离清洗装置06及样本检测装置07相邻设置,且样本孵育装置05、混匀装置04、磁分离清洗装置06及样本检测装置07位于样本装载装置01的同一侧。具体的,混匀装置04、磁分离清洗装置06及样本检测装置07围绕样本孵育装置05设置。转运抓杯装置08可运动至混匀装置04、样本孵育装置05、磁分离装置及样本检测装置07的上方。这样,转运抓杯装置08转移反应容器时,能够按照最短的运动路径运动,如转运抓杯装置08将混匀装置04上的反应容器转移到样本孵育装置05中,将样本孵育装置05中的反应容器转移到磁分离清洗装置06中,将磁分离清洗装置06中的反应容器转移到样本孵育装置05或样本检测装置07中,以缩短反应容器的转移路径,提高处理效率,进而提高化学发光分析与的处理效率。而且,采用上述方式对化学发光分析仪的各个结构进行布局时,能够使得整机布局合理紧凑、体积小巧,还能便于用户操作使用,方便维护。
分注装置03可运动至样本装载装置01与试剂装载装置02的上方,同时分注装置03还能运动至混匀装置04处,实现样本与试剂的转移。样本装载装置01具有吸样本工位,试剂装载装置02具有吸试剂工位,分注装置03在吸样本工位吸取样本装载装置01中样本容器内的样本后并转移到混匀装置04的反应容器中,分注装置03还在吸试剂工位吸取试剂存储装置中试剂容器内的试剂后并转移到混匀装置04的反应容器中。可以理解的是,样本与试剂转移原则上没有先后顺序要求,即可以先转移样本后转移试剂,也可以先转移试剂后转移样本。
转运抓杯装置08将反应容器转移到混匀装置04中;分注装置03将样本与试剂分别转移至混匀装置04的反应容器中,并由混匀装置04混匀;转运抓杯装置08将反应容器从混匀装置04转移至样本孵育装置05中进行孵育,转运抓杯装置08还将孵育后的反应容器转移至磁分离清洗装置06进行分离清洗,并将分离清洗后的反应容器转移到孵育测光装置中进行发光检测。具体的,转运抓杯装置08将空的反应容器转移到混匀装置04中,然后分注装置03分别向反应容器中添加样本与试剂,然后反应容器中的样本与试剂在混匀装置04上混合均匀并形成混合物,随后转运抓杯装置08将反应容器从混匀装置04转移到样本孵育装置05上,样本孵育装置05对反应容器中的混合物进行孵育,使得混合物在反应容器中形成待测物和杂质;然后转运抓杯装置08将反应容器从样本孵育装置05中转移到磁分离清洗装置06中,通过磁分离清洗装置06将反应容器中的杂质清洗去除,留下待测物;转运抓杯装置08再将清洗后的反应容器转移到样本检测装置07中,通过样本检测装置07对反应容器中的待测物进行检测,以获取样本的各项参数。
具体的,转运抓杯装置08具有沿XYZ方向运动的运动机构及抓杯手,抓杯手设置在运动机构上,运动机构能够带动抓杯手实现三维空间任一位置运动,实现三维空间的任意位置抓取与释放反应容器,进而实现反应容器的转移。具体的,运动机构带动抓杯手能够在反应容器装载装置14处抓取空的反应容器转移到混匀装置04上,能够将混匀装置04中的反应容器转移到样本孵育装置05中,能够将样本孵育装置05中的反应容器转移到磁分离清洗装置06或样本孵育机构中,能够将磁分离清洗装置06中的反应容器转移到混匀装置04或样本检测装置07中等等。运动机构包括电机配合按照XYZ三个方向运动的同步带结构,以实现相应方向的运动,当然,同步带结构也可替换为齿轮齿条结构、链传动结构或者其他能够实现直线运动的结构。
本发明的化学发光分析仪用于对待测物的发光值进行检测,以获取样本的各项参数。为了增加待测物检测时的发光值,本发明的化学发光分析仪在分离清洗后的反应容器中添加底物,底物附着于待测物上,能够增加待测物的发光值,保证样本检测的准确性。具体的,化学发光分析仪中放置底物容器,底物容器用于盛装底物,通过液路向反应容器中添加底物。这样能够减少添加底物时承载反应容器的结构设置,减少反应容器的转移次数,进而减小整机体积。经磁分离清洗后,向反应容器中添加底物,使得底物与待测物混合,再将反应容器从磁分离清洗装置06转移到样本孵育装置05中,经过孵育后再由转运抓杯装置08转移到样本监测装置中,通过样本检测装置07对待测物进行发光检测,以获取样本的各项参数。
作为一种可实施方式,化学发光分析仪还包括承载平台11。样本装载装置01与试剂装载装置02并排位于承载平台11的右侧,磁分离清洗装置06、样本检测装置07、样本孵育装置05及混匀装置04位于承载平台11的左后侧,混匀装置04位于承载平台11的中部区域,分注装置03位于承载平台11的右后侧,转运抓杯装置08位于承载平台11的左前侧。承载平台11起承载作用,并通过支架支撑,为全自动化学发光免疫分析仪的各个结构提供放置空间。具体的,样本装载装置01、试剂装载装置02、磁分离清洗装置06、 样本检测装置07、样本孵育装置05及混匀装置04均设置于承载平台11上,化学发光分析的液路、电气部件等均设置于承载平台11的下方,这样能够充分利用空间,使得化学发光分析仪的整机体积小。
可以理解的是,定义用户操作化学发光分析仪的一侧为承载平台11的前侧,相应的,与承载平台11的前侧相对的一侧为承载平台11的后侧,与承载平台11的前侧相邻的两侧为承载平台11的左右侧。具体的,如图1所示,承载平台11具有左侧、右侧、前侧及后侧,承载平台11的右侧为样本试剂管理区,左侧为反应容器调度反应检测区,后侧为辅助支撑区。其中,右侧的样本试剂管理区的最右侧边缘放置底物容器,样本装载装置01与试剂装载装置02设置于右侧的样本试剂管理区中,并位于底物容器的左侧。分注装置03位于样本试剂管理区后侧的上方,且分注装置03可在样本试剂管理区的上方运动,以分别在样本装载装置01吸取样本以及试剂装载装置02处吸取试剂。可以理解的是,混匀装置04与试剂装载装置02分设于样本装载装置01的两侧,或者,混匀装置04与样本装载装置01分设于试剂装载装置02的两侧。也就是说,样本装载装置01与试剂装载装置02的左右位置不受限制,即样本装载装置01在左,试剂装载装置02在右,也可为是试剂装载在左,样本装载装置01在右,样本装载装置01与试剂装载装置02并排设置即可。在本实施例中,样本装载装置01位于试剂装载装置02的右侧。
承载平台11的左侧为反应容器调度反应检测区,样本孵育装置05、混匀装置04、磁分离清洗装置06、样本检测装置07及转运抓杯装置08均设置在左侧的反应容器调度反应检测区。转运抓杯装置08位于承载平台11的左前侧,且转运抓杯装置08的运动区域能够覆盖反应容器调度反应检测区,实现反应容器的转移。在本实施例中,混匀装置04位于样本孵育装置05的右侧,磁分离清洗装置06与样本检测装置07位于样本孵育装置05的后侧,这样,以样本孵育装置05为反应调度中心,形成一个小布局,转运抓杯装置08将反应容器在混匀装置04、样本孵育装置05、磁分离清洗装置06以及样本检测装置07之间转移时,能够缩短反应容器的转移路径,提高转移效率,而且还能减少占用空间,进而减小整机体积。较佳地,混匀装置04与样本孵育装置05并排设置,磁分离清洗装置06与样本检测装置07并排设置。承载平台11的后部及底部设置支撑整机运行的气液路与电路系统,这样设置的目的是:将可能需要维护的部件尽可能的放到整机外围,降低将来在客户端可能出现的维护复杂度。
可选地,化学发光分析仪还包括反应容器装载装置14,反应容器装载装置14设置于承载平台11上,且反应容器装载装置14位于样本孵育装置05的前侧,用于承载反应容器;转运抓杯装置08可运动至反应容器装载装置14的上方,以抓取反应容器装载装置14中的反应容器,并转移至混匀装置04中。具体的,反应容器装载装置14位于反应容器调度反应检测区,并位于样本孵育装置05远离磁分离清洗装置06的一侧,用于承载反应容器,提高输送效率。当然,在实用新型的其他实施方式中,反应容器装载装置14也可以被替换,即不采用反应容器装载装置14输送反应容器,反应容器可以直接放置到样本孵育装置05中。较佳地,反应容器装载装置14输送的反应容器通常为一次性耗材,当 然,反应容器也可以被回收重复利用。可选地,反应容器重复利用时,也可不采用反应容器装载装置14输送反应容器。而且,反应容器是指承载并能够进行样本反应、检测分析的耗材,如反应杯、试管、样本玻片、样本管等等。在本实施例中,反应容器指反应杯。
可选地,本发明中的反应容器装载装置14包括托盘结构,托盘结构上放置有序排列的反应容器,方便转运抓杯装置08抓取反应容器。较佳地,反应容器装载装置14的数量为两个,两个反应容器装载装置14并排设置。两个反应容器装载装置14可交替使用,即支持测试过程中更换托盘结构。当其中一个反应容器装载装置14中的反应容器被抓取完后,需要取出托盘结构装载装满反应容器,此时,另一反应容器装载装置14可以继续化学发光分析仪提供反应容器,避免因反应容器装载组装置空载而影响化学发光分析仪的运行,使得化学发光分析仪能够连续进行样本检测,提高效率。当然,在本发明其他实施方式中,反应容器装载装置14还可以为抽屉结构。
又可选地,本实用新型的化学发光分析分析仪使用一次性的反应容器进行样本检测,发光检测完成后,使用后的反应容器需要被回收。化学发光分析仪还包括废料箱15,废料箱15设置于承载平台11上,并位于反应容器装载装置14的右侧,用于回收检测后的反应容器;转运抓杯装置08可运动至废料箱15的上方,以抓取样本孵育装置05处的反应容器,并转移到废料箱15中。具体的,废料箱15顶部具有开口,转运抓杯装置08能够将检测后的反应容器经废料箱15的缺口进入废料箱15。废料箱15能够连续回收使用后的反应容器,避免占用样本孵育装置05中的位置,同时还能避免使用后的反应容器被乱丢弃。废料箱15装满反应容器或者需要清空废料箱15中的反应容器后,可以将废料箱15从化学发光分析仪上取下,清空后再将废料箱15安装回全化学发光分析仪上。
作为一种可实施方式,化学发光分析仪还包括主控制装置及电源装置,电源装置与主控制装置电连接,主控制装置分别与样本装载装置01、试剂装载装置02、分注装载、混匀装置04、样本孵育装置05、磁分离清洗装置06、样本检测装置07、转运抓杯装置08、反应容器装载装置14等电连接,主控制装置及电源装置位于承载平台11下方。主控制装置中集成软件控制系统,通过软件控制系统实现化学发光分析仪的各个部件相互配合运动,提高全自动化学发光免疫分析仪的运行效率。主控制装置设置于承载平台11的下方能够减小各个零部件的体积,大大减小在承载平台11上占用的空间,使得化学发光分析仪的结构紧凑,有利于化学发光分析仪的小型化趋势。而且,主控制装置将各个零部件的控制集成在一起,方便维护操作,还能降低机器的成本和故障率。
可选地,化学发光分析仪还包括底物注入机构12,底物注入机构12用于向反应容器内添加底物。当需要向反应容器中添加底物以增加发光值时,通过底物注入机构12实现。需要说明的是,底物的注入是在磁分离清洗装置06清洗完成后再进行,避免底物与杂质结合,并通过样本孵育装置05进行孵育后,使得底物与待测物充分反应,便于对样本进行发光检测。可选地,底物注入机构12包括底物安装座及底物针,底物针安装于底物安装座上,底物针的一端通过液路连接底物容器,反应容器被转移到底物针的下方,以将底物容器中的底物添加到反应容器中。
参见图1,在一种实施方式中,底物注入机构12设置于磁分离清洗装置06上。也就是说,反应容器中的混合物清洗完成后,直接在磁分离清洗装置06中添加底物。参见图5,当然,在另一实施方式中,底物注入机构12设置于样本孵育装置05上。也就是说,样本孵育装置05具有底物注入孔,转运抓杯装置08将清洗后的反应容器转移到样本孵育装置05的底物注入后,底物注入机构12将底物添加到反应容器后,转运抓杯装置08再将反应容器转移到样本孵育装置05的其他位置进行孵育操作,这是因为样本孵育的时间长,为避免耽误后续样本注入底物,所以将添加完底物的反应容器转移走。可以理解的是,将底物注入机构12集成到磁分离清洗装置06或样本孵育装置05上,能够在减小反应容器转移路径的同时,还能避免设置多余的机构设置底物注入机构12,降低成本,减小占用空间。
参见图1,又可选地,化学发光分析仪还包括底物承载部13,底物承载部13设置于承载平台11上,并位于承载平台11的右侧边缘,底物承载部13承载底物容器,并由底物注入机构12吸取底物容器中的底物输送至反应容器中。在本实施例中,底物承载部13位于试剂装载装置02的右侧。底物承载部13承载底物容器,液路的一端伸入到底物容器中,液路的另一端与底物注入机构12连接,用于将底物容器中的底物输送到反应容器中。而且,底物承载部13还具有底物泵,通过底物泵作为动力源输送样本。并且,底物承载部13在承载平台11上偏前侧设置,这样,底物承载部13装载底物容器后,能够使得底物容器靠近用户,方便用户更换底物容器。较佳地,底物承载部13可以承载两个底物容器,这样,可以选择任一底物容器输送底物,便于设备运行时更换底物容器。
作为一种可实施方式,样本孵育装置05包括孵育块及设置于孵育块下方的加热部件,加热部件用于对孵育块加热,孵育块上具有呈阵列设置的多个孵育孔,孵育孔用于放置反应容器并进行孵育操作,孵育孔还用于暂存检测后的反应容器。孵育块能够承载反应容器,反应容器被放到孵育块的孵育孔中,孵育块对反应容器进行孵育操作,使得反应容器中的混合物能够充分反应,形成待测物与杂质。加热部件能够加热孵育块,孵育块能够承载反应容器,并对反应容器中的混合物进行加热,实现孵育的功能。加热部件能够将反应容器中的混合物在正式测量前加热到预设温度如约34℃等以确保反应正常进行。而且,多个孵育孔可以呈任意方式排布,本实施例中,多个孵育孔呈阵列式排布,这样能够增加孵育块承载反应容器的数量。这样,孵育块在满足孵育要求的同时,还能节省占用空间,进而利于减小整机的体积。当然,当本发明的孵育块上的孵育孔数量不够使用时,可以更换一个具有更多孵育孔的孵育块,以满足用户不同的使用需求。示例的,孵育块为金属结构,这样能够有利于热量散发,进而便于加热孵育块中的反应容器。加热部件为加热膜,加热膜通电后能够产生热量,该热量可对孵育块加热。当然,在本实用新型的其他实施方式中,加热部件还可为加热丝、加热棒或者其他能够加热的结构。本发明的样本孵育装置05相对于目前的盘形孵育盘的结构而言,本发明的样本孵育装置05的结构更加简单,设计空间更加紧凑,且调用更加灵活,不必受限于孵育盘周期性的运动。
孵育孔用于容置孵育孔,通过加热部件对孵育块加热,以对孵育孔中的反应容器进行 加热;同时,孵育块上的孵育孔还能够容置测光后的反应容器,即具有暂存测光后反应容器的目的。在测试过程中废料箱15已满或被认为拿走,此时正好有反应容器测完光,需要丢弃。为了保证测完光的反应容器不会占用样本检测装置07的位置而影响下一样本的检测,转运抓杯装置08将测完光的反应容器转移到样本孵育装置05未被使用的孵育孔,暂存。等废料箱15清空或认为归还后,转运抓杯装置08再将暂存在样本孵育装置05内的测光后的反应容器丢弃到废料箱15中。
可以理解的是,反应容器中的混合物在孵育时需要花费一定的时间,转运抓杯装置08可以将经混匀装置04混合均匀的反应容器转移到孵育块的孵育孔中,由于本发明的化学发光分析仪的各个组件同时运动,使得各个位置都有反应容器进行操作,因此,转运抓杯装置08可以进行其他操作而无需等待该反应容器孵育完成,如可以进行将反应容器转移到混匀装置04上、将反应容器从磁分离清洗装置06转移到混匀装置04或样本检测装置07上、或者将孵育完成的反应容器转移到磁分离清洗装置06中。
可选地,样本孵育装置05还包括温度传感器,温度传感器设置于孵育块上,用于检测孵育块的温度以及控制加热部件对孵育块的加热温度。温度传感器与主控制装置电连接,主控制装置通过温度传感器还能检测孵育块的温度,还通过温度传感器控制加热部件对孵育块进行加热,并调节加热部件加热孵育块的加热温度;具体的,温度传感器通过检测孵育块温度控制加热部件的输出功率,进行孵育块整体温控。若温度传感器检测孵育块温度偏低时,温度传感器控制加热部件加热,以调高孵育块的温度;若孵育块的温度偏高,温度传感器控制加热部件停止加热。
又可选地,样本孵育装置05还包括温度开关,温度开关设置于孵育块上,温度开关用于控制加热部件停止加热。温度开关与加热部件电连接,温控开关还与主控制装置电连接。当温度传感器的温控功能失效时,主控制装置控制温度开关切断加热部件的电源,实现高温保护,避免高温导致反应容器中的样本失效,保证样本检测结果准确。
参见图1和图6,作为一种可实施方式,化学发光分析仪具有测光孔09,测光孔09独立于样本孵育装置05设置,用于承载待检测的反应容器,样本检测装置07设置于测光孔09处,用于对测光孔09中的反应容器进行发光检测。也就是说,测光孔09设置于承载平台11上,并位于样本孵育装置05的周侧,样本检测装置07对应测光孔09设置,也位于样本孵育装置05的周侧。示例的,测光孔09与样本检测装置07位于样本孵育装置05的孵育块的后侧。转运抓杯装置08将磁分离清洗装置06清洗后去除杂质的反应容器转移到测光孔09中,样本检测装置07能够对测光孔09中的反应容器内的待测物进行测光,获取光强信号值,以获取样本的各项参数。
参见图5,当然,在本发明的其他实施方式中,测光孔09也可位于孵育块的边缘位置,且样本检测装置07设置于孵育块的侧面,并与测光孔09相对应。也就是说,测光孔09设置于孵育块上,相应的,样本检测装置07设置于孵育块上,并对应测光孔09,以检测测光孔09中反应容器内待测物的光强信号值,即将孵育功能与检测功能集成设置,这样能够使得整机结构紧凑,减小体积,同时还能缩短反应容器的转移路径,提高整机运行 效率。而且,样本检测装置07位于样本孵育装置05的后侧面,并与磁分离清洗装置06并排设置,这样能够减小占用空间,提高空间利用率,进而减小整机体积。示例的,测光孔09位于孵育块的边缘位置,方便样本检测装置07进行发光检测。
参见图1,而且,化学发光分析仪上还具有测光开口,该测光开口连通测光孔09与样本检测装置07。检测时,转运抓杯装置08将反应容器转移到测光孔09中,样本检测装置07对反应容器中待测物的发光值进行检测,反应容器发出的光可以通过测光开口照射到样本检测装置07上,实现反应容器中待测物的发光检测。当测光孔09设置在承载平台11上,测光开口位于承载平台11上;当测光孔09设置在孵育块上,测光开口也相应的位于孵育块上。
可以理解的是,若待测物无需添加底物,则转运抓杯装置08直接将磁分离清洗后的反应容器从磁分离清洗装置06转移到样本检测装置07中进行发光检测。若待测物添加底物后无需混匀操作,转运抓杯装置08直接将磁分离清洗后的反应容器从磁分离清洗装置06转移到样本孵育装置05中,经孵育块对反应容器进行孵育操作后,转运抓杯装置08再将反应容器从样本孵育装置05的孵育孔转移到测光孔09中,通过样本检测装置07对测光孔09中的反应容器进行发光检测。若待测物添加底物后需混匀操作,转运抓杯装置08先将磁分离清洗后的反应容器从磁分离清洗装置06转移到混匀装置04上中,使得反应容器中的待测物与底物混合均匀,然后转运抓杯装置08将反应容器从混匀装置04转移到孵育块的孵育孔中,经孵育块对反应容器进行孵育操作后,转运抓杯装置08再将反应容器从孵育孔转移到测光孔09中,由样本检测装置07进行发光检测。
进一步地,为了保证测光过程中,测光孔09中的反应容器不受环境光的影响,化学发光分析仪还包括开关门,开关门可开关的盖设于测光孔09上,样本检测装置07对测光孔09中的反应容器进行发光检测时,开关门关闭测光孔09。样本检测装置07不进行发光检测时,开关门处于打开状态;当转运抓杯装置08将反应容器转移到测光孔09后,开关门关闭测光孔09,以实现对测光孔09中反应容器的遮光,提高样本检测装置07检测样本的准确性;当测完光后,开关门打开,转运抓杯装置08再将测光孔09的反应容器丢弃。
参见图1和图5,作为一种可实施方式,混匀装置04的数量为至少两个,至少两个混匀装置04并排设置且各自独立驱动,在其中一个混匀装置04进行添加样本与试剂操作时,其余混匀装置04能够带动反应容器进行混匀操作。至少两个混匀装置04相互独立设置,相互独立运行,这样,至少两个混匀装置04能够承载至少两个反应容器,使得化学发光分析仪能够对至少两个混匀装置04执行操作,减少反应容器的等待时间,提高化学发光分析仪的运行速度。具体的,转运抓杯装置08将反应容器分别转移到至少两个混匀装置04上,对其中一个混匀装置04中的反应容器添加样本与试剂的同时,其余混匀容器可以对添加完样本与试剂的反应容器进行混匀操作,使得加样本试剂过程与混匀过程同时进行,提高样本的处理速度,进而提高整机的工作效率及测试通量。
在本实施例中,混匀装置04包括第一混匀装置041与第二混匀装置042,第一混匀 装置041与第二混匀装置042并排设置,位于样本孵育装置05的右侧。采用第一混匀装置041与第二混匀装置042后,本发明的化学发光分析仪提出了一种双混匀机构交替运行的工作模式,以提高化学发光分析仪的工作效率和测试通量。具体的,第一混匀装置041在进行加样本与试剂操作时,第二混匀装置042能够对已经添加完样本与试剂的反应容器进行混匀操作。即当本周期内分注装置03在第一混匀装置041进行添加样本与试剂操作时,第二混匀装置042可执行上周期已完成添加样本和试剂后需要混合物混匀的操作,混匀完后,转运抓杯装置08将其反应容器转移到样本孵育装置05中;下周期,第一混匀装置041执行混合物混匀操作,第二混匀装置042执行一个新测试的样本、试剂分注操作。本发明的化学发光分析仪采用第一混匀装置041与第二混匀装置042,将原本在一个周期要完成抓空的反应容器到混匀装置04、样本和试剂分注、混合物混匀、混匀后转移到样本孵育装置05,变成在两个周期内通过两个混匀装载交替完成这些动作,这就相当于缩短了一个周期的时间,提高了仪器的工作效率和测试通量。
可以理解的是,本发明的化学发光分析仪采用两个混匀装置04后,当其中的一个混匀装置04发生故障时,另一混匀装置04仍然能够运行,进行混匀操作,使得整机依然可使用。此时,化学发光分析仪采用单个混匀装置04运行的工作模式,其他装潢中会相应调整测试节拍,与单个混匀装置04配合工作。在其他实施方式中,混匀装置04的数量还可以多于2个,此处不再赘述。
可选地,本发明的化学发光分析仪采用两个混匀装置04,不仅能够完成样本与试剂的分注和混匀功能,而且还在两个周期内完成样本预稀释的功能,即,本周期内分注装置03在第一混匀装置041进行样本、试剂分注操作后,随后本周期内就完成混合物混匀的操作,下个周期,转移抓杯装置抓取一个空的反应容器放到第二混匀装置042上,分注装置03将到第一混匀装置041吸取混匀后的混合物后,运动到第二混匀装置042排入液体,然后分注装置03分注相应的试剂,完成样本预稀释功能。这样,能够拓宽本发明的化学发光分析仪的检测范围,以获取更宽范围的检测参数。
参见图6,当然,在本发明的另一实施方式中,当化学发光分析仪采用一个混匀装置04进行混匀操作时,化学发光分析仪也可以进行固定稀释操作,以拓宽检测范围。具体的,化学发光分析仪还具有固定稀释孔16,固定稀释孔16与混匀装置04相邻设置,固定稀释孔16用于承载待稀释的反应容器,由分注装置03将固定稀释孔16中反应容器内的混合物转移到混匀装置04的反应容器中,并由分注装置03转移试剂进行样本稀释。可选地,固定稀释孔16可以设置在孵育块上,当然,固定稀释孔16也可以独立于孵育块,设置于承载平台11上。固定稀释孔16设置在孵育块的右侧边缘,以缩短分注装置03转移混合物与试剂的路径,提高效率。混匀装置04进行样本、试剂分注操作后,随后就完成混合物混匀的操作,然后转移抓杯装置抓取一个空的反应容器放到固定稀释孔16中,分注装置03将到混匀装置04吸取混匀后的混合物后,运动到固定稀释孔16处排入液体,然后分注装置03分注相应的试剂,完成样本预稀释功能。这样,能够拓宽本发明的化学发光分析仪的检测范围,以获取更宽范围的检测参数。
参见图1,作为一种可实施方式,分注装置03包括XYZ三个方向运动的分注驱动机构及分注针,分注针安装于分注驱动机构上,这样,分注驱动机构能够带动分注针做XYZ三个方向运动,实现三维空间任意位置的运动,实现转移样本与试剂。具体的,分注驱动机构能够带动分注针运动到样本装载装置01处吸取样本、运动到试剂装载装置02处吸取试剂、运动到混匀装置04处进行添加样本或试剂以及向孵育块的固定稀释孔16中添加试剂等等,实现样本与试剂的转移操作。分注驱动机构可采用电机配合按照XYZ三个方向运动的同步带结构,当然,同步带结构还可替换为链传动结构、齿轮齿条结构或者其他能够实现直线运动的结构。吸取样本或试剂时,分注驱动机构带动分注针下降,吸取完成后,分注驱动机构带动分注针上升;然后,分注驱动机构带动分注针在水平面内运动至混匀装置04处;分注驱动机构带动分注针下降,分注针排出样本或试剂,排出完成后,分注驱动机构带动分注针上升;分注驱动机构带动分注针回到初始位置或者再次进行样本或试剂转移操作。
可以理解的是,分注针每吸取或排出样本与试剂后,都需要进行清洗,以避免样本或试剂残留在分注针的外壁导致交叉污染而影响样本检测的准确性。因此,化学发光分析仪还包括清洗池10,清洗池10位于混匀装置04远离孵育块的一侧,且清洗池10还位于样本装载装置01的后侧,清洗池10用于对分注装置03进行清洗。具体的,分注驱动机构带动分注针运动到清洗池10处,分注驱动机构带动分注针下降,分注针伸入到清洗池10中,通过清洗池10中的清洗液对分注针的内壁与外壁进行清洗;清洗完成后,分注驱动机构带动分注针上升,然后进行其他操作。可以理解的是,清洗池10与液路连接,用于输送清洗液以及排出清洗后的废液。当然,在本发明的其他实施方式中,液路也可与分注针连接,向分注针内输送清洗液,以清洗分注针的内壁,当通过清洗池10清洗外壁时,分注针内的清洗废液可以通过清洗池10排出。
作为一种可实施方式,样本装载装置01包括多个并排设置的样本架,每个样本架承载多个样本容器。可以理解的是,多个样本架并排方式在承载平台11上,分注装置03能够运动到样本装载装置01上吸取各个位置处样本容器中的样本。当然,在本发明的其他实施方式中,也可通过样本传动机构如齿轮传动结构、链传动结构等将样本架输送到指定位置,分注装置03在指定位置吸取样本。
而且,承载平台11的右侧具有放置样本装载装置01的区域,多个样本架并排放置在该区域中,只要区域能够放得下,就可以放置样本架。因此,本发明的样本装载装置01可扩展性强,用户可以根据实际使用需求增加或者减少样本架。在本实施例中,样本架的数量为六个,当然,用户可以根据实际使用需求增减样本架。
参见图1,作为一种可实施方式,试剂装载装置02包括多个阵列排布的试剂盒021,每个试剂盒021用于承载多个试剂容器。多个呈阵列式排布的试剂盒021能够增加承载试剂容器的数量,在有限的范围内可以尽可能多的放置试剂容器,以满足样本不同的检测需求。可以理解的是,试剂盒021可以呈至少两行排布。每个试剂盒021中承载成列设置的多个试剂容器,可以理解的是,试剂盒021可以为一个盒状结构,试剂容器可以直接放置 在试剂盒021中,当然,试剂盒021也可以当成试剂容器,试剂盒021内分隔成多个空间,每一空间为一个试剂容器,可以放置一种类型的试剂;也可以为一个托盘的结构,试剂容器放置在试剂盒021上;当然,也可两种结构的组合。
可以理解的是,当本发明的化学发光分析仪采用磁微粒方法对样本进行检测时,试剂装载装置02中需要放置磁微粒试剂,但是,磁微粒试剂中的磁微粒长时间不动会沉淀到试剂容器的底物,分注装置03无法吸取试剂时无法吸出磁微粒,影响检测结果。因此,试剂装载装置02还能混合试剂容器中的磁微粒试剂。当然,当化学发光分析仪不进行磁微粒检测时,试剂装载装置02也可不会试剂容器中的试剂进行混匀。
具体的,试剂装载装置02还包括试剂存储传动机构022及试剂存储驱动机构,多个试剂盒021呈两行设置,且分别位于试剂存储传动机构022的两侧,每个试剂盒021具有混匀位及静止位,用于分别承载反应容器;试剂存储传动机构022传动连接试剂存储驱动机构与多个试剂盒021,并带动试剂盒021的混匀位上的试剂容器转动,以混匀试剂容器中的试剂。可以理解的是,试剂盒021具有多个静止位及一个混匀位,多个静止位与混匀位并排设置,且混匀位位于试剂盒021的边缘位置,待混匀的试剂容器放置于混匀位上,而且,多个试剂位呈两行并关于试剂存储传动机构022对称设置,且试剂存储传动机构022分别对应混匀位。需要混匀时,试剂存储驱动机构驱动试剂存储传动机构022带动混匀位中的试剂容器转动,以使试剂容器中的磁微粒试剂混合均匀。
进一步地,试剂存储传动机构022包括试剂存储传动结构、具有齿部的混匀部件0222及多个混匀齿轮底盘0221,试剂存储传动结构与混匀部件0222连接,混匀齿轮底盘0221位于试剂盒021的混匀位上,并承载试剂容器,混匀部件0222通过齿部与两侧的多个混匀齿轮底盘0221传动连接,试剂存储传动结构通过混匀部件0222带动混匀齿轮底盘0221转动,以混匀试剂容器中的试剂。参见图3,也就是说,混匀部件0222的数量为一个,一个混匀部件0222分别与两侧的混匀齿轮底盘0221啮合连接。试剂存储传动结构连接混匀部件0222及试剂存储驱动机构,试剂存储驱动机构通过试剂传动结构带动混匀部件0222运动,以带动混匀齿轮底盘0221转动,以带动混匀齿轮底盘0221上的试剂容器运动,实现混匀试剂容器中的磁微粒试剂混匀。
参见图1和图2,当然,具有齿部的混匀部件0222的数量也可以为两个,两个混匀部件0222对称设置,齿部分别朝向试剂盒021放置,与试剂盒021中的混匀齿轮底盘0221相啮合。两个混匀部件0222分别与试剂存储传动结构连接,混匀齿轮底盘0221位于试剂盒021的混匀位上,并承载试剂容器,两个混匀部件0222分别通过齿部与对应的多个混匀齿轮底盘0221传动连接,试剂存储传动结构通过混匀部件0222带动混匀齿轮底盘0221转动,以混匀试剂容器中的磁试剂。
可以理解的是,带有齿部的混匀部件0222在本实施例中为齿条结构,混匀部件0222带动混匀齿轮底盘0221转动。即混匀部件0222做直线运动,试剂存储驱动机构带动试剂存储传动结构做直线运动,可以为气缸结构、齿轮配合电机结构等等。
参见图1和图4,本发明的化学发光分析仪采用对称布置磁微粒、混匀功能的试剂装 载装置02,以扩展试剂容器的数量,使得结构显得更加紧凑,节省设计空间。可选地,试剂盒021的延伸方向与样本装载装置01存储样本容器的延伸方向相平行或相垂直。即试剂装载装置02可以横向放置,也可以竖向放置,都能够满足吸取试剂的要求。
参见图1,作为一种可实施方式,磁分离清洗装置06包括磁分离底座、清洗液注入机构、清洗液排出机构及磁分离吸附机构。磁分离底起承载作用,用于承载磁分离清洗装置06的各个零部件,同时磁分离底座还能承载待清洗的反应容器。转运抓杯装置08将反应容器从样本孵育装置05上转移到磁分离底座上,经磁分离清洗装置06清洗后,转运抓杯装置08再将反应容器从磁分离底座上转移走。若添加底物,则在磁分离底座上添加完底物后,转运抓杯装置08再将反应容器从磁分离底座上转移走。清洗液注入机构与液路连接,能够向磁分离底座的反应容器中注入清洗液,清洗液排出机构与液路连接,能够将磁分离底座的反应容器中清洗废液及清洗后的清洗液排出。可以理解的是,清洗液注入机构注入清洗液的步骤在清洗液排出机构排出清洗液之前进行。而且,清洗液注入机构与清洗液排出机构成对使用。
示例的,清洗液注入机构与清洗液排出机构的数量均为多个,即磁分离清洗装置06具有多阶磁分离清洗功能。在本实施例中,清洗液注入机构与清洗液排出机构的数量均为三个。三个清洗液注入机构与三个清洗液排出机构交错分布于磁分离底座上,即清洗液排出机构的两侧分别设置清洗液注入机构,清洗液注入机构的两侧分别设置清洗液排出机构。可以理解的是,液路为管路,并配合泵等结构。示例的,清洗液注入机构包括注液针及注液针座,注液针座固定于清洗液进液孔,注液针用于将清洗液添加至反应容器中。清洗液排出机构包括排液针及排液管路,通过排液针吸取反应容器中的清洗废液,并通过排液管路排出。
当转运抓杯装置08将反应容器抓取到磁分离清洗装置06后,磁分离清洗装置06周期递进,通过多个清洗液注入机构与清洗液排出机构完成反应容器的多磁分离清洗,清洗完成后,通过底物注入机构12将底物注入到反应容器中,注入完后,转运抓杯装置08将反应容器抓出。
磁分离吸附机构设置于磁分离底座中,并位于反应容器转动路径的两侧。磁分离吸附机构能够将反应容器中的磁珠吸附到反应容器的侧壁上,实现反应容器中待测物与杂质的清洗。可以理解的是,通过至少一次分离清洗操作对反应容器中的待测物与杂质进行清洗,保证待测物的纯度,进而保证样本检测结果的准确性。在本实施例中,磁分离吸附机构为磁铁。
本发明还提供一种化学发光分析仪的分析方法,分析方法包括如下步骤:
加杯步骤,转运抓杯装置08将空的反应容器转移到第一混匀装置041与第二混匀装置042中;
加样本步骤,分注装置03将样本装载装置01中的样本转移到第一混匀装置041的反应容器中;
加试剂步骤,分注装置03将试剂存储装置中的试剂转移到第一混匀装置041的反应 容器中;
混匀步骤,第一混匀装置041将反应容器中的样本与试剂混合均匀;同时,对第二混匀装置042执行加样本步骤与加试剂步骤;
孵育步骤,转运抓杯装置08将混匀的反应容器转移到样本孵育装置05中,样本孵育装置05对反应容器中混合均匀的混合物进行孵育操作;
磁分离清洗步骤,转运抓杯装置08将孵育后的反应容器转移到磁分离清洗装置06中,磁分离清洗装置06去除孵育后的反应容器中的杂质;
检测步骤,转运抓杯装置08将清洗后的反应容器转移到样本检测装置07中,样本检测装置07对清洗后的反应容器中的待测物进行发光检测。
进行一次加试剂操作时,即一步法反应工作流程,用户在反应容器装载装置14中手动装载两盒反应容器,分别放置于两个反应容器装载装置14上,由转运抓杯装置08在反应容器装载装置14上抓取一个新的反应容器,放置于第一混匀装置041上。分注装置03在样本装载装置01中吸取样本,转移到第一混匀装置041上的反应容器中;分注装置03还运动到试剂装载装置02吸取所需的试剂后转移到第一混匀装置041上的反应容器中;需要说明的是,分注装置03每吸取一次组份,分注装置03就运动到清洗池10进行一次外壁清洗。加完样本和试剂后,第一混匀装置041执行固定时间的混合物混匀,使得样本和试剂充分混匀。
为提高整机的工作效率,第一混匀装置041在执行混合物混匀的过程中,转运抓杯装置08抓取空的反应容器到第二混匀装置042上,同样分注装置03在第二混匀装置042上完成样本和试剂的加入。第一混匀装置041和第二混匀装置042交替运行。待第一混匀装置041完成混合物混匀,转运抓杯装置08将混匀后的反应容器转移到样本孵育装置05上的孵育孔中,进行一段时间的孵育,后续完成混匀的反应容器将按照顺序依次放置在样本孵育转置上的孵育孔中。
在到达预定的孵育时间后,转运抓杯装置08将反应容器抓取到磁分离清洗装置06中,此后的数个周期内,对反应容器中的混合物进行清洗,清洗完成,底物注入机构12将底物注入到清洗完成后的反应容器中,底物注入完成的反应容器由转运抓杯装置08将其转移到样本转运装置上的孵育孔中,进行固定时间的底物孵育,待底物孵育完成后,测光孔09上的开关门将打开,转运抓杯装置08将反应容器转移到测光孔09中,然后测光孔09上的开关门将关闭,样本检测装置07开始执行一段时间的测光操作。
待样本检测装置07完成测光操作后,测光孔09上的开关门再次被打开,转运抓杯装置08将反应容器抓取到废料箱15上方,将其抛弃。
作为一种可实施方式,分析方法还包括如下步骤:
在混匀步骤之后或在磁分离清洗步骤之后,再执行至少一次加试剂步骤。
也就是说,对样本进行多次加试剂操作,而且,是对经混匀后孵育前或孵育后清洗后的反应容器进行至少一次加试剂操作,以使得样本能够充分反应。在本实施例中,对经混匀后孵育前或孵育后清洗后的反应容器进行一次加试剂操作,即总共进行两次加试剂操 作,为两步法反应工作流程。
具体的,转运抓杯装置08将完成混合物孵育的反应容器从样本孵育装置05的孵育孔中转移到混匀装置04或将完成磁分离清洗分离后的反应容器从磁分离清洗装置06转移到混匀装置04,然后分注装置03运动到试剂装载装置02中试剂容器中吸取试剂,加入到混匀装置04的反应容器中,完成加入第二步试剂的操作。后续动作同一步法反应工作流程。
作为一种可实施方式,分析方法还包括如下步骤:
在孵育步骤之前,执行稀释步骤,稀释步骤用于稀释样本。
本发明的化学发光分析仪还能进行稀释操作,以拓宽化学发光分析仪的检测范围,以获取更宽范围的检测参数。
进一步地,稀释步骤包括如下步骤:
转运抓杯装置08将空的反应容器转移到第二混匀装置042中;
分注装置03将第一混匀装置041中反应容器内的混合物部分转移到第二混匀装置042的反应容器中;
对第二混匀装置042中的反应容器执行加试剂步骤。
本周期内,分注装置03在第一混匀装置041进行样本、试剂分注操作后,随后本周期内就完成混合物混匀的操作,下个周期,转移抓杯装置抓取一个空的反应容器放到第二混匀装置042上,分注装置03将到第一混匀装置041吸取混匀后的混合物后,运动到第二混匀装置042排入液体,然后分注装置03分注相应的试剂,完成样本预稀释功能。以拓宽化学发光分析仪的检测范围,以获取更宽范围的检测参数。
作为一种可实施方式,在加样本步骤之前与之后,以及在加试剂步骤之前与之后,分析方法还包括清洗步骤,分注装置03运动至清洗池10处进行清洗。
也就是说,分注装置03的分注针每吸取或排出样本与试剂后,都需要进行清洗,以避免样本或试剂残留在分注针的外壁导致交叉污染而影响样本检测的准确性。
作为一种可实施方式,试剂容器装载磁微粒试剂时,在加试剂步骤之前,分析方法还包括试剂混匀步骤,用于混匀试剂容器中的磁微粒试剂。
当本发明的化学发光分析仪采用磁微粒方法对样本进行检测时,试剂装载装置02中需要放置磁微粒试剂,在分注装置03吸取试剂之前,试剂装载装置02混合试剂容器中的磁微粒试剂,使得磁微粒试剂不会沉积在底部而混合均匀,保证分注装置03能够吸取磁微粒。当然,当化学发光分析仪不进行磁微粒检测时,试剂装载装置02也可不会试剂容器中的试剂进行混匀。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书的记载范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说, 在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
