生化分析测试仪
技术领域
本发明涉及用于测定临床生理指标检测的生化分析测试仪，尤其是快速测定生化指标的生化分析测试仪。
背景技术
随着科学技术的进步，检验医学领域中的床边体外诊断实验（POCT：Point of Care Testing）应运而生并得到快速发展。20世纪五十年代出现的“浸与读”（dip-and-read）的干化学法是指将液体检测样品直接加到干式试剂条上，以被测样品的水分作为溶剂引起试剂条上特定的化学反应，从而进行样品分析的方法。生化干式试纸法以其携带方便、操作简单测定速度快等特点，在现场快速检测中也发挥重要作用。随着免疫反应和分子生物技术的引进，医学干式试纸法的检验领域扩展到血糖、妊娠、血凝状态、心肌损伤、酸碱平衡、感染性疾病等的检测，以及治疗药物浓度监测（TMD）、酒精含量检测、凝血试验、血液中生化指标的分析、传染病过筛、外科手术时的激素水平及微芯片DNA诊断和药物滥用检测等。依靠目测法判断干化学测试试纸的检测结果，只能作为定性判断或半定量的判断。因此为使快速检测试纸的判读更准确，与之配套的小型化检测仪器逐步发展起来。这些检测仪器操作简便，出结果快速、准确。并且这些检测仪器所得到的资料还可以实现远距离无线传输至实验室计算机管理系统或形成电子病历。
美国专利US 4780283揭示了一种干式化学试纸分析仪。该分析仪包括固定不动的检测光源，装载测试试纸条的半球面的工作平台。通过弹簧之间的相互作用将半球面的工作平台运送到检测光源处进行检测。由于只是利用了弹簧之间的机械作用力，不但在生产上要求有很精确地控制过程，增大了生产成本，而且利用弹簧的相互作用很难控制反应试剂条和检测光源之间的正确位置，影响检测结果。而半球面的结构，增加了整个分析仪器的体积。另一方面，弹簧使用寿命短，需要定期的更换弹簧，这会给仪器的使用者带来麻烦。
美国Praxsys Biosystems Inc. 公司开发了一种可用于定性和定量判断的快速免疫检测系统，在美国专利US6136610中揭示，该系统由检测仪和与之配套的检测试纸盒组成。该系统使用单通道，即一次仅能检测单一患者样本。由于该检测仪器一次只能检测一项指标，因此检测效率比较低。
中国专利申请200910160639.5公开了一种多通道便携式胶体金试纸快速测试装置，主要包括：4个独立的检测通道、ARM数据处理器、键盘和LCD部分。该发明的检测装置能快速并且高通量的完成多种检测项目。但是该中国专利申请的4个独立的检测通道和整个检测仪是一个整体，仪器使用者不能通过更换检测通道来随意更换测试项目。
中国专利申请200410052202.7公开了一种快速诊断侧流分析系统和方法，该检测系统包括1个主单元和1至20个测试模块，并通过USB或蓝牙无线接收器连接到电脑主机，电脑主机通过软件控制检测仪运行。该专利申请还公开了主单元与测试模块之间被设计成相对独立关系，主单元发生故障时，所有的测试装置可以被拆卸下来并与另一个主单元重新装配。该专利申请所述的测试模块从主单元中拆卸下来是一个非常复杂的过程，需要启开很多零部件。另一方面，所述的测试模块并不是一个封闭的结构，当被拆卸下来的测试模块内留存有测试时的样品或测试试剂时，这些残留的样品或试剂会被暴露在环境中，不仅污染了周围的环境，还会对操作人员的生命安全构成危险。
在现有的检测仪中，往往都是单通道的，即一次只能检测单一患者的样品。这种单通道的检测仪在单位时间内测试的样品有限，在处理人数众多的大规模体检时，往往会造成体检人员的大量滞留。
在进行样品检测的加样过程中，测试试纸先被放在实验桌面上，然后滴加样品。由于测试试纸都会比较薄从而会紧粘在实验桌上，当滴加完样品，需要重新拿起测试试纸时，就会比较困难，需花费较多的时间，延误了正确的检测时间。
另一方面，如果操作者失误，在没有关紧测试门的情况下就开启检测程序，这样外界干扰光线就会进入测试部位，造成检测结果不准确，特别是利用光学检测原理的检测仪。

具体实施方式
下面结合具体附图对本发明进行详细的说明。这些具体的实施例仅仅是在不违背本发明精神下的有限列举，并不排除本领域的一般技术人员把现有技术和本发明结合而产生的其他具体的实施方案。
如图1所示，本发明所述的生化分析仪1包括一个主控装置10和一个或者一个以上相互独立的测试装置100，主控装置10与测试装置100通过电连接器140和导线连接。每个测试装置100能根据主控装置10传输的指令，各自独立地完成检测项目并将检测结果传输给主控装置10输出。每个测试装置100之间被设计成相对独立的关系，测试装置100可以自由地与主控装置10进行反复的拆装。
如图1至图6所示，主控装置10的机壳内包括有主电源11（接通外部商品用电后给生化分析仪的各部分供电）。主控装置10还包括有分析仪的总开关12、操作面板13和打印机14。总开关12、操作面板13和打印机14分别与主电源11电连接。操作面板13是一个触摸显示屏，既可显示检测过程的界面以及检测结果，又可方便操作者触摸屏幕进行操作。
主控装置10的机壳内并列地设置有一个或者一个以上尺寸大小与测试装置100基本相当的存放腔15。为了使测试装置能快速平稳地被推入到主控装置的存放腔15内，存放腔15的至少两侧壁分别设计有导轨16，或者在存放腔15的底部设计有导轨17，或者在存放腔的两侧壁和底部都设计有导轨。所述导轨与测试装置上的滑块或滑轮（未图示）配合。当测试装置被组装到主控装置或从主控装置上拆卸下来的过程中，测试装置上的滑块或滑轮在导轨内滑动，引导测试装置进入主控装置的存放腔或离开存放腔15。
如图4所示，所述的存放腔15内也可放入大小和形状与测试装置100基本相当的试剂存放单元18，所述试剂存放单元18内可以设置一个或者多个试剂存放架19，用于存放测试用的测试元件，该测试元件可以是测试试剂或者试剂桶等。该设计的优点在于，可根据实际需要，主控装置10内的存放腔15全部安装测试装置100，或者部分安装测试装置100，其它的安装试剂存放单元18，从而使设计更灵活。如图4所示的生化分析仪1，包括了一个主控装置10、两个测试装置100和一个试剂存放单元18。作为更多变更的实施方式，生化分析仪1可以包括一个主控装置10、一至十个，甚至十个以上的测试装置100和一至十个，甚至十个以上的试剂存放单元18，并且测试装置100和存放单元18的数量可以依需要随意结合。操作者可以把进行检测时需要的试剂提前放在试剂存放架19中。当进行检测时，操作者可以非常方便地从分析仪的试剂存放单元中取出相应的反应试剂。如果测试装置被长期使用，则其对应试剂存放单元也可长期存放在主控装置内，与测试装置形成一对一的关系，防止错用试剂。另外试剂都归类放置在试剂存放单元中，使得操作台面不至于堆满试剂瓶，防止发生试剂瓶倒翻等危险事件。
主控装置10的外壳上装配有USB接口26、风扇20、总电源接入口21等。为了使被推入的测试装置100稳定地保持在存放腔15内，主控装置的后盖上对应每个测试装置的位置还可以包括锁扣孔22。
操作面板13可以是LCD、LED触摸屏面板或一些具有按键的LCD、LED面板。操作面板13通过铰链23与主控装置10连接，也可通过铰链（未图示）和支架24与主控装置10连接。
如图7至图9所示，测试装置100包括一个底座101，运送检测试纸条的载台102设计在底座上，光源发射和接收装置103位于载台102的上方。在底座101上固定设计有左支架104和右支架105，左右支架将载台102包围在其内。光源发射和接收装置103安装在左右支架上，或者在左右支架上固定设计有上支架106，光源发射和接收装置103被安装在上支架106上。载台102可以在预先设定的轨道往复移动，光源发射和接收装置103可以靠近和远离载台102，载台102和光源发射和接收装置103的移动轨迹或者移动轨迹的延长线在同一平面内相互交叉或者在同一平面内的正投影相互交叉。
在至少一个支架104或105上设计有步进电机107，步进电机上装有齿轮108。运送检测试纸条的载台102包括用于承载检测试纸条109的托盘110。在载台102的至少一侧固定地设计有齿条板111。所述齿轮108与载台102上的齿条板111啮合。当步进电机工作时，驱使驱动齿轮转动，然后再驱使齿条板111作直线运行，从而将与齿条板相连的载台送到测试区域或从测试区域退出。步进电机对运动的精度比较高，因此当齿轮带动齿条板的运动，不仅提高了运送测试试纸的速度，而且也提高了测试的稳定性和准确性。
底座101的中部位置固定设计有导轨座112，该导轨座112与试纸条载台102上的导轨113配合使用，载台102能在测试装置内沿着导轨座滑动，从而运送测试条到达检测位置或退出测试区域。所述的导轨113设计于载台102的下部。
在载台上位于试纸条的测试区域的下方有一个温度控制装置114。当测试的环境温度不符合预先设定的温度范围时，温度控制装置将自动调节温度（例如加热），使测试环境的温度符合预先设定的温度范围。温度控制装置包括电阻加热装置，并通过陶瓷片或金属片传递温度。
测试装置底座101的左右两侧还可以各安置有一个滑块座120，滑块座120通过螺栓固定在底座101上。滑块121固定设计在滑块座120上，该滑块121能在存放腔15侧壁的导轨16内自由滑动，从而带动整个测试装置在存放腔15内移动，测试装置被推入存放腔准备进行被分析物的检测，或者被移出存放腔。带有滑块的滑块座还可以设置在底座的下部，与存放腔内的底部导轨17配合使用。作为变更设计，滑块座120和滑块121也可以是一个整体，还可以是一个与导轨16相配合的条状物。
为了更好的保护测试载台和光源发射和接收装置，在测试装置100的前后左右还可以各设计有挡板122-126，即右挡板122、左挡板123、上挡板124、前挡板125和后挡板126。在前挡板125上设计有一个测试装置门127，测试装置门127与前挡板125可以通过铰链连接。当测试装置不使用或正在检测时，测试装置门是关闭的。当测试装置中的试纸条载台需要运送检测试纸条时，测试装置门打开，方便操作者存放或取出测试试纸。所述挡板对测试装置中的试纸条载台和光源发射和接收装置起到很好的保护，使载台和光源发射和接收装置免受外力撞击，并可防止粉尘污染。同时当测试装置被整个拿出时，载台上残留的试剂或样品不会被暴露在外界环境中，防止对环境的污染。
光源发射和接收装置103包括推动光源发射和接收装置上下运动的电动马达130（优选步进电机），光源发射装置131。光源发射和接收装置103还包括控制光源装置运动位置的光耦开关132，所述光藕开关132与所述电动马达130电连接，用于控制所述电动马达130运行和制动。所述光藕开关132具有发光孔133，光源发射和接收装置具有遮挡板134。所述遮挡板134相对于发光孔133具有遮挡发光孔133和离开发光孔133两个位置。当光源发射和接收装置向下运行过程中，当遮挡板134位于光藕开关132的发光孔133上方，此时光路畅通，电源一直保持供电状态，光源装置在电动马达130转动下继续向下运动。当遮挡板134阻挡了光藕开关132的发光孔133时，光路被切断，从而关闭电动马达130的电源，光源装置不再下行，同时开启样品检测光源131对样本进行检测和分析。
每个测试装置100还可以包括独立的微处理器，可以执行包括但不限于例如控制光源发射装置、监控托盘的运动位置、测试环境温度和加热片加热等程序，并通过数据传输接口向外界传输数据。
测试装置100还可包括电源接口和数据传输接口，实现给测试装置供电并传输测试结果。测试装置100也可用集成的电连接器140。所述的电连接器是将电源接口和数据传输接口集成在一起的装置，这就使测试装置有更多的空间存放其他配件，也减少了生产的工序，提高生产效率。测试装置通过电连接器与主控装置连接，接受主控装置对测试装置供电，或将数据传输给主控装置的数据输出装置。测试装置的电连接器也可连接到其他的数据输出装置上。
每个测试装置上所采用的检测光源可以相同或不同。当多个测试装置所采用的检测光源相同时，可以提高检测的速度和效率。如果测试装置所采用的检测光源互不相同，各个测试装置可以测定相同或者不同样品的相同或者不同的生化参数，从而实现一机多用。其他任何的主控装置与测试装置之间的组合方式都是合适的。
为了保证测试装置被很好的固定在主控装置上，可以在测试装置和主控装置上设置将测试装置固定到主控装置上的锁扣结构。所述的锁扣结构可以是螺纹锁扣（例如螺栓与螺帽、螺钉与螺纹孔）的固定方式、卡扣锁扣或磁块锁扣。所述的磁块锁扣的结构，如图10至图13所示，包括至少三个磁块，第一磁块151、第二磁块152和第三磁块153。第一磁块151设计在第一装置上，第二磁块152和第三磁块153设计在第二装置上。第一磁块151和第二磁块152相对的两个面的磁性相异（分别为S极和N极），第二磁块152和第三磁铁153相对的两个面的磁性相同（同为S极或者同为N极）。第一磁块151、第二磁块152和第三磁块153在垂直于其相对面的方向上的投影大致重叠。如果要将两个装置相互锁扣住时，将带有第一磁块151的第一装置推向带有第二磁块152的第二装置靠近，第一装置和第二装置最终通过磁力吸附在一起，此时，第三磁块153远离第二磁块152。如果要将两个装置相互分离，此时将第三磁块153推向第二磁块152靠近，利用第三磁块153和第二磁块152以及第一磁块151之间的相互排斥力，削弱了第一磁块151和第二磁块153之间的磁性吸力，从而使第一装置和第二装置相互分离。
本发明所述的生化分析仪如图10至图11所示的实施例中，第一磁块151设计在测试装置100的后挡板126上。第二磁块152嵌合在主控装置10的锁扣孔22内。在主控装置后盖上设计有两个支撑架154，所述支撑架154分别设计在锁扣孔的两侧。第三磁块153通过弹簧片155与支撑架154连接。第一磁块151和第二磁块152相对的两个面的磁性相异（分别为S极和N极），第二磁块152和第三磁块153相对的两个面的磁性相同（同为S极或者同为N极）。图10所示的是测试装置100被推入到主控装置10的存放腔15内的状态，此时，第一磁块151和第二磁块152因为磁铁异性相吸，这种磁吸力使得测试装置被牢牢地吸在主控装置上，而不会从主控装置中滑出。如图11所示，当需要抽出测试装置100时，将第三磁块153向第二磁块方向推，因为第二磁块152和第三磁块153相对的两个面的极性是相同的，并且第三磁块153和第一磁块151相对的面的极性也是相同的，根据磁铁的同性相斥的原理，第三磁块153对第一磁块和第二磁块都有一个排斥作用，削弱了第一磁块151和第二磁块152之间的磁吸力。随着第三磁块153的靠近，这种排斥力会基本抵消第一磁块151和第二磁块152之间的磁吸力。从而，测试装置100就可以很容易地被从主控装置的存放腔中抽出。
图12是磁块锁扣结构的另一种实施例，第三磁块153可以通过滑杆扣157在滑杆156上滑动。图13是磁块锁扣结构的另一种实施例，第三磁块153通过弹簧扣159与弹簧158相互抵触，弹簧有被第三磁块压缩和舒展的状态。
主控装置和测试装置之间测试流程如图14所示。工作流程为：首先打开电源，生化分析仪开机并进入开机自检程序，待开机自检结束后，进入预热程序，当生化分析仪的测试温度符合预先设定的温度范围时，检测仪处于等待测试状态，操作者选择需要进行测试的测试装置，放入测试试纸条后，分析仪启动测试，测试结束后，输出测试结果，取出测试试纸条。若还要进行下一个样品的检测则再次放入新的测试试纸条，开始新一轮的测定。若所有样品都已测试完成，则关机。
以下为本发明的另一实施例。
如图15至21所示，生化分析测试仪1a，包括安装在机壳2a内的主控单元50a及至少二个测试单元100a。在机壳上对应于每一个测试单元100a都安装有测试单元门3a。
主控单元50a分别与生化分析测试仪1a的总电源开关、数据输入/输出控制系统和测试单元100a通过数据线、电线等方式连接。数据输入/输出包括液晶显示器4a、USB接口、数据线接口和打印机等。
测试单元100a包括送样装置110a和测试光源装置111a。
测试单元100a的送样装置110a包括承载检测测试试纸的托盘114a，在托盘的下方有一传热板115a，通过该传热板将加热装置116a产生的热量传递到检测区域。所述的加热装置116a可以选自功率电阻板等电器元件。在温度加热装置116a的下方放置了一块下压块隔热板117a，将加热装置上产生的热量阻隔在此，不再往其他部位传递。电动马达118a被固定在电动马达固定板119a上。电动马达开启时，推动托板螺母做上下运动。送样装置110a通过托盘114a将检测试验条送到预先设定的检测位置，优选的是通过光耦开关121a控制托盘114a到达预先设定的检测位置。所述光耦开关121a具有发光孔122a，所述托盘114a具有下边缘123a位于所述发光孔122a上方。所述下边缘123a相对于发光孔122a具有遮挡发光孔122a和离开发光孔122a两个位置。当托盘114a的下边缘123a位于光耦开关121a的发光孔122a上方，则光路畅通，此时电动马达电源一直保持供电状态。在电动马达118a转动下，托盘114a继续向上运动。当托盘114a继续上升并接触到检测光源装置112a后，由于检测光源装置112a固定不动，托盘就不能继续前行，光源装置会对托盘114a产生持续向下的压力。但光耦开关在电动马达的带动下还在继续向上运动，直到托盘114a的下边缘123a阻挡了光耦开关121a的发光孔122a。当发光孔被遮挡后，光路就被切断，从而关闭电动马达的电源。此时，检测测试试纸已经到达了检测位置，生化分析测试仪开启样品检测光源装置112a进行样品的分析。
所述的测试光源装置111a包括测试光源112a和上压块113a。所述上压块113a与所述下挤压板117a地配合设置用于对所述检测测试试纸产生压强。在本发明的一具体实施例中，压强一般为1kgf/cm2-3kgf/cm2，较佳的为2 kgf/cm2。所述的光源装置至少有两方面的作用：1）将光传入至检测测试试纸的反应区域，并接收反应区的反射光。2）向托盘的测试区域传送光，并接收反射光信息，将反射光信息提供给系统，用以判断检测测试试纸是否已经放在了试纸载台上等待测试。
在测试单元内还设有生化分析测试仪开启检测的磁感应启动装置。磁感应启动装置产生的磁感应信号连接到主控单元上。在一个实施例中，磁感应启动装置包括设置在测试单元内的磁感应开关10a和设置在测试单元的单元门上的磁块11a，其材料选自磁钢，磁铁当。当单元门关闭时，磁感应开关10a感应到单元门上磁块的磁场信号，将磁场信号传递到主控单元后，主控单元判断出单元门的具体位置，例如单元门是否闭合或开启，从而由主控单元对是否启动检测做出判断。
另一方面，生化分析测试仪机壳的材质可以选自铁或钢等能与磁块产生吸附力的材料，或者在测试单元内安装一铁块等。当测试单元门关闭时，受接触点磁铁的磁力作用，安装在单元门上的磁块能将单元门牢牢地吸合在主机的机壳上，从而实现单元门的锁合。因此生化分析测试仪并不需要再添置其他的单元门锁合装置。
磁块以黏胶固定或螺丝固定等方式固定在单元门上。磁块可以被封闭在单元门内或放置在单元门外。
在分析测试仪的机壳2a上还装有测试试纸加样操作台5a。在加样品时，测试试纸可以暂时存放在所述的测试试纸操作台5a上。在一个实施例中操作台是一个卡槽型结构，所述的操作台由上板6a和下板7a组成，且上板和下板之间留有缝隙8a，所述的缝隙间距正好是测试试纸的厚度或稍微比测试试纸厚度大。操作台的缝隙卡住测试试纸的前端部分，测试试纸的加样部位和拿捏处都在操作台的外面，将测试试纸拿捏部位的底面不触碰到实验桌面。这样非常方便操作者加样和拿起测试试纸。当加样时，操作者首先将测试试纸卡在操作台的卡槽中，然后进行加样。由于测试试纸的拿捏部分是凌空的，在加完样品后，操作者能够很方便地拿起已经加有样品的测试试纸，将该测试试纸放入测试单元的检测平台上。所述测试试纸操作台可以安装在测试单元门的下方、侧面或上方。
如图20所示的实施例中，所述生化分析测试仪包括一个主控单元和三个独立的测试单元。主控单元与电源、打印机、显示系统、USB接口、参数输入系统等连接。主控单元还分别与三个测试单元连接。测试单元独立的完成各自的检测，并把测试结果传输给主控单元，由主控单元输出检测结果。测试单元包括反射式光度计、机械传动装置和温度控制装置等。
如图21所述的生化分析测试方法，包括：
1）开启生化分析仪测试仪，并设置测试参数，所述生化分析测试仪包括主控单元及至少二个相互独立的测试单元，主控单元分别与分析仪电源控制开关、数据输出装置、输入控制系统和测试单元相互连接，每个测试单元包括送样装置110a和测试光源装置111a。
2）将加了样品的测试试纸放入其中一个测试单元中。
3）生化分析测试仪判断检测区是否有测试试纸存在，若没有，生化分析测试仪给出重新放置测试试纸的提示信息。
4）生化分析测试仪判断测试单元门是否关闭，若没有，生化分析测试仪给出关闭单元门的提示信息。
5）当测试试纸已经存在于检测区和单元门已经关闭这两组信息都具备时，生化分析测试仪开始启动检测并输出检测结果。
在一个实施例中，生化分析测试仪在接收到测试试纸已经存在于检测区和单元门已经关闭这两组信息后，还会就检测开始时间是否超过预先设定时间做出判断。若超时，则生化分析测试仪给出重新更换测试试纸的提示信息。若不超时，生化分析测试仪开始启动检测并输出检测结果。
在测试过程中，每个测试单元独立进行检测，互不干扰，从而提高了测试速度，在同一时间内可以检测更多的样品。
生化分析测试仪利用测试单元的光源装置来判读检测区是否已经放置了测试试纸。测试光源发出测试光，并通过托盘检测区的反射光信息判断检测区是否有测试试纸存在。若没有，生化分析测试仪给出重新放置测试试纸的提示信息。
生化分析测试仪通过磁感应信号来判断测试单元门是否关上。当单元门关闭时，磁感应开关10a感应到单元门上磁块的磁场信号，将磁场信号传递到主控单元后，主控单元判断出单元门的具体位置，例如是否闭合或开启，从而由主控单元对是否启动检测做出判断。
本发明所述的生化分析仪及测试方法可用于葡萄糖、胆固醇、高密度脂肪酸、低密度脂肪酸、甘油三酯、尿酸、胆红素、总蛋白、血红蛋白、酮体等一系列生理生化指标的检测。
