Description

全自动便隐血检测分析仪 技术领域
本发明涉及医学检测领域，具体涉及一种全自动便隐血检测分析仪，即一种全自动FOB检测分析仪。
背景技术
“FOB”：fecal occult blood的英文缩写，指大便中的隐血，简称便隐血，即少量的消化道出血，通常不引起大便颜色的改变，红细胞被消化破坏，大便外观无异常改变，肉眼和显微镜下均不能证实出血，只有在化验大便时才发现大便中有少量的血细胞，由于长期少量出血，常伴有贫血症状。由于便隐血无法通过肉眼直接发现，导致绝大多数早期消化道恶性肿瘤患者无法及时发现并早期干预治疗，从而延误了治疗的最佳时机，如同隐性杀手一般潜伏在人们身体中。
现有技术中检测便隐血多通过采便器与卡塞配合检测，患者采集便样后，将带有便样的稀释液滴入卡塞的滴样孔，观察检测结果。如此操作对于大批量检测效率低，且带有便样的稀释液暴露在空气中，形成异味，污染环境。
CN 103543285A公开了一种便隐血自动检测设备，用于检测样本盒，样本盒包括透明套筒和置于透明套筒中的采便器和试纸条，该检测设备包括：送入通道和送出通道，二者并列设置，分别用于独立运行地传送样本盒，转送平台，位于送入通道和送出通道之间，推杆，用于将送入通道上的样本盒经由转送平台推送至送出通道上，以及图像采集装置，设置在送出通道的一侧，其中，图像采集装置用于获取试纸条上所呈现的色带信息。
该便隐血自动检测设备存在以下问题：
送入通道和送出通道并列设置，增加了设备的占地面积。
在送入通道和送出通道上样本盒放置随意，间隔无序，在送入通道和送出通道以及转送平台上样本盒都容易发生倾倒，从而可能影响后续样本盒的检测，严重时需要设备的停机检测。
推杆动作也容易将样本盒推到，也存在上述问题。下压件动作的时候和样本盒不能很好的配合完成下压，导致无法检测，或者下压件动作可能将样本盒推到，无法完成后续的图像采集。该设备的推板机构同样存在上述问题。
另外，该设备需要人工将样本盒中的便样进行摇匀，增加了人力，降低了检测效率。
综上所述，现有技术中至少存在以下问题：样本盒在检测过程中容易发生翻倒、倾倒问题。
发明内容
本发明的主要目的在于提供一种全自动便隐血检测分析仪，以解决检测过程中容易发生翻倒、倾倒问题。
为此，本发明提出一种全自动便隐血检测分析仪，用于检测样本盒，样本盒包括透明套筒和置于透明套筒中的采便器和试纸条，全自动便隐血检测分析仪包括：进料链条和主传送链条；多个夹持样本盒的夹持装置，分别设置在进料链条和主传送链条上；转送装置，设置在主传送链条限定的区域之间；用于在样本盒的移动过程中下压采便器的下压装置，设置在主传送链条的上方；图像采集装置，获取主传送链条上的样本盒中的试纸条上所呈现的色带信息。
进一步地，进料链条和主传送链条均位于一个水平平面内，夹持装置安装在进料链条和主传送链条的侧向，样本盒竖直的夹持在夹持装置中，夹持装置的侧面夹持样本盒的侧面。
进一步地，夹持装置是弹性材料制作的弹性夹持装置，弹性夹持装置包括：由弹性材料形成的开口槽，开口槽的开口位于竖直平面内。
进一步地，转送装置包括：能在进料链条和主传送链条之间移动的拉杆、以及位于进料链条和主传送链条之间的转送支撑平台，转送支撑平台支撑样本盒。
进一步地，拉杆包括：上拉杆和位于上拉杆之下的下拉杆，上拉杆为水平设置的L形，上拉杆所在的平面高于进料链条和主传送链条的顶面，下拉杆包括：水平设置的横杆和连接在横杆端部的竖杆，竖杆垂直横杆设置，横杆低于进料链条和主传送链条的底面，竖杆的顶面低于上拉杆所在的平面，转送支撑平台中设有供竖杆移动的开孔，开孔的宽度小于样本盒的宽度，下拉杆能够从转送支撑平台的底部伸出进入进料链条的内部。
进一步地，全自动便隐血检测分析仪还包括：将样本盒从主传送链条上送出的出料装置。
进一步地，全自动便隐血检测分析仪还包括：废料支撑平台，支撑出料装置送出的样本盒，废料支撑平台位于进料链条和主传送链条之间，并且废料支撑平台与转送支撑平台位于相同的平面上，废料支撑平台的纵向宽度小于样本盒的长边长度。

本发明通过在进料链条和主传送链条上设置夹持装置，使得样本盒在检测过程中能够得到较好的夹持，无论是在转送过程中，还是在样本盒受到下压以及检测采便器的过程中，样本盒都能得到夹持装置的限位、夹持，因而克服了翻转、倾倒的问题；优选，该夹持装置是弹性材料制作的弹性夹持装置，这样可以适应各种型号的采便器。
进而，为了能使传送样本盒的过程与样本盒的夹持过程能够有机的结合起来，本发明将进料通道和检测传送的主传送通道都采用链条式传送结构，这样，夹持装置既能很好地夹持样本盒，又能不影响传送，做到传送与夹持的有机配合。

具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图说明本发明。
如图1所示，本发明提出一种全自动便隐血检测分析仪，用于检测样本盒30，样本盒包括透明套筒和置于透明套筒中的采便器和试纸条，样本盒的具体结构可以参考中国专利文献103543285中的结构。
全自动便隐血检测分析仪包括：
进料链条10和主传送链条20是环形的，主传送链条20位于进料链条10的一侧，二者互不包含，以便各自独立；作为较佳选择，进料链条10和主传送链条20为矩形或近似矩形、圆形或近似圆形的各种形状的环形封闭链条，只要进料链条10和主传送链条20的形状可以设置于整机外壳104中即可；进料链条10和进料链条主动轮11连接，主传送链条20和主传送链条主动轮21连接；链条式输送可以防止翻转，精确定位，而且如果整个检测分析仪的长宽一定的情况下，链条式输送的效率更高；
多个夹持样本盒的夹持装置40，分别设置在进料链条10和主传送链条20上，由于进料链条10和主传送链条20为链条式结构，进料链条10和主传送链条20可以由多节链条单元连接形成，每节链条单元上可以安装夹持装置40用于夹持样本盒30。进料时，进料链条10上的夹持装置40夹持样本盒30，检测时，主传送链条20上的夹持装置40夹持样本盒30，使得无论是在进料、转送、下压、以及后续的检测、采集患者信息和检测结果拍照的过程中，样本盒30都能得到夹持装置40的限位、夹持，因而克服了翻转、倾倒的问题，并能精确定位，夹持装置40可以由橡胶或其他弹性材料制成，从而适应各种型号的采便器；
转送装置，设置在主传送链条20限定的区域之间，用于将样本盒30从进料链条10转送到主传送链条20上；
下压装置，设置在主传送链条20的上方，用于在样本盒30的移动过程中下压采便器；
图像采集装置，例如为拍照装置80，获取主传送链条20上的样本盒30中的试纸条上所呈现的色带信息，通过该信息能够得知检测结果，图像采集装置设置于废料排出装置70之前。
本发明与现有技术的主要区别在于：进料方式(进料通道)和检测传送方式(检测传送通道)分别采用进料链条10和主传送链条20，并且，采用夹持装置40夹持样本盒30，进料通道和检测传送的通道都采用链条式传送结构，这样，夹持装置40既能很好的夹持样本盒30，又能不影响传送，做到传送与夹持的有机配合。
进一步地，如图1，进料链条10和主传送链条20均位于一个水平平面内，也便于样本盒30的平稳传送和精确定位，夹持装置40安装在进料链条10和主传送链条20的侧向，样本盒30竖直的夹持在夹持装置40中，夹持装置40无需具有底面，夹持装置40的侧面夹持样本盒30的侧面，这样，会产生夹持装置40对样本盒30的侧向夹持力和夹持力矩，这种侧向夹持力和夹持力矩能够有效对抗样本盒30的翻转力矩，能够有效地防止样本盒30倾斜。
进一步地，如图6所示，夹持装置40是弹性材料制作的弹性夹持装置，弹性夹持装置包括：由弹性材料形成的开口槽301，开口槽301的开口位于竖直平面内，开口为侧向，以便夹持和输出样本盒30。开口槽301例如为矩形开口槽，开口槽301的长度或者夹持装置40的夹持长度为一段线段，能够节约用料并使整个便隐血检测分析仪的重量减轻，开口槽301的长度或夹持装置40的夹持长度小于样本盒30的长度，使得夹持装置40与样本盒30的接触不是点接触，而是形成线接触或面接触，以达到较大的接触面积，形成稳定的夹持力矩。
进一步地，全自动便隐血检测分析仪还包括：将样本盒30从进料链条10转送到主传送链条20上的转送装置，以实现样本盒的转送。
进一步地，如图4和图5所示，转送装置包括：能在进料链条10和主传送链条20之间移动的拉杆50、以及位于进料链条10和主传送链条20之间的转送支撑平台53，转送支撑平台53在转送过程中支撑样本盒30。拉杆50可以由电机驱动，实现往复运动。通过拉杆50的拉动以及转送支撑平台53的稳定支撑，可以顺利实现样本盒30的快速转送。
进一步地，如图2和图3所示，拉杆50包括：上拉杆51和位于上拉杆51之下的下拉杆52，上拉杆51为水平设置的L形或其他形状，用于勾住样本盒30，只要上拉杆51所在的平面高于进料链条10和主传送链条20的顶面的任何其他形状的上拉杆51都能够实现本发明，以使上拉杆51在往复的水平运动中不受进料链条10、主传送链条20、进料轨道15和主传送轨道的影响，主传送链条20设置在主传送轨道中，主传送轨道由具有开口的主传送链条外壳形成，主传送链条外壳例如由工程塑料或钢板或工程用铝或可加工树脂材板制成，包围主传送链条20的外侧和底部，对主传送链条20上的样本盒30起到两个方向限位的作用，并在下压装置90下压时，支撑主传送链条20的样本盒30的底部，不会使主传送链条20因下压产生变形，不会影响主传送链条20传送样本盒30，相对于以往的传送带，本发明的主传送轨道或主传送链条外壳在下压过程中更能使传送样本盒30的过程保持稳定，不会形成倾斜和侧翻。进料轨道15由具有开口的进料链条外壳形成，进料链条外壳包围进料链条10的外侧和底部，对进料链条10上的样本盒30起到两个方向限位的作用。
如图3，下拉杆52包括：水平设置的横杆520和连接在横杆520端部的竖杆522，横杆520和竖杆522形成竖直平面内的L形或其他形状，以便在竖直平面内勾住样本盒30。竖杆 522竖直设置，横杆520低于进料链条10和主传送链条20的底面，以避免横杆520在水平移动中受进料链条10和主传送链条20影响，竖杆522的顶面低于上拉杆51所在的平面，以形成样本盒30在上下部位都能受到拉动，避免倾斜翻转，转送支撑平台53中设有供竖杆522移动的开孔55，开孔55的宽度小于样本盒30的宽度，保证样本盒30不会从开孔55中漏下去同时实现对样本盒30的支撑，竖杆522从转送支撑平台53的底部伸出或从开孔55伸出进入进料链条10的内部。只要下拉杆52能够满足上述条件的任何其他形状都能够实现本发明。上拉杆51在水平平面内拉动样本盒30，下拉杆52从竖直平面内拉动样本盒30，二者的拉动平面相互垂直，这样，样本盒30在拉动过程中，受力更加合理，均衡，防止翻转的效果更好，而且使得样本盒30在上下两个部位都能得到顺利的拉动，不会受到主传送链条20、进料链条10的影响，同时，由于转送支撑平台53对样本盒30的支撑作用，拉动过程更加平稳，而且该结构紧凑，便于安装在较小的空间内，尤其，适合安装在图7和图8所示的整机外壳104中。当然，其他形状的上拉杆51和下拉杆52也是可行的，只要其能够满足上述条件并适合安装在整机外壳104中。
进一步地，如图1和图6所示，全自动便隐血检测分析仪还包括：将样本盒30从主传送链条20上送出的出料装置60。出料装置60例如为推动块或推杆类部件等能够进行往复运动的装置，可以由电机驱动，将样本盒30从主传送链条20上的夹持装置40相对于主传送链条20的竖直方向推出。
进一步地，如图6所示，全自动便隐血检测分析仪还包括：废料支撑平台71，支撑出料装置60送出的样本盒30，废料支撑平台71位于进料链条10和主传送链条20之间，并且废料支撑平台71与转送支撑平台53位于相同的平面上，以形成进料、出料的平稳衔接。此外，废料支撑平台71的纵向宽度小于样本盒30的长边长度，防止样本盒30在排出阶段发生旋转。
进一步地，如图6所示，全自动便隐血检测分析仪还包括：将样本盒30从废料支撑平台71相对于主传送链条20的水平方向推走的废料排出装置70，以便及时清理废料支撑平台71，排出检测完的样本盒30，保证检测的连续。废料排出装置70为能移动的部件，例如为推动块或推杆类部件等能够进行往复运动的装置。样本盒在出料过程中由废料支撑平台71支撑，所以不会掉下来，即使样本盒30倒了也没有关系，因为样本盒30全程都是密封状态的，不会对检测分析仪和环境有污染。
进一步地，全自动便隐血检测分析仪还包括：驱动进料链条10运动并使样本盒30振动的步进电机。进料链条10通过进料链条主动轮11的转动而运动，进料链条主动轮11与步进电机连接，步进电机不仅起到驱动作用，而且通过调节步进电机转速产生振动，振动采便器，实现便样和稀释液的混合，不需要人工摇匀的过程，节约了人力，提高了效率。如图1所示， 全自动便隐血检测分析仪还包括：下压装置90，用于将样本盒30中的采便器上盖下压刺破采便器下端的易撕材料，试纸条开始反应进行爬条，下压装置90下压样本盒时，主传送轨道的底部为距离主传送链条一定高度的平台，支撑样本盒30。
如图7和图8所示，全自动便隐血检测分析仪还包括：容纳进料链条外壳、主传送链条外壳、进料链条主动轮11、主传送链条主动轮21、夹持装置40、各传感器等部件的整机外壳104。整机外壳104上设有进料口101，进料口101与进料链条10连通，用于向进料链条10进料，也就是加入待检测的样本盒。通过整机外壳104，可以保护内部部件，可以整体搬运，便于移动。
全自动便隐血检测分析仪还包括：设置在整机外壳104上的出料口105，从废料支撑平台71推出的样本盒30，通过出料口105离开全自动便隐血检测分析仪。检测分析仪的整机外壳104在进料口101处具有保护盖102，保护盖上带有感应装置，可以在检验员打开保护盖进料的同时使进料链条停止运动，实现对检验员的保护，主传送链条不停止工作，可以继续后续的图像采集和排出动作。
优选地，全自动便隐血检测分析仪还包括与条码扫描装置88、与图像采集装置信号连接的信息处理单元，图中未示出，设置在整机外壳上的打印装置107、以及控制面板109。条码扫描装置88读取条码信息，图像采集装置获取主传送链条上的样本盒中的试纸条上所呈现的色带信息，通过信息处理单元进行处理以生成检测结果，并通过打印装置107打印出来，或者通过控制面板109显示结果。条码扫描装置88可以位于整个分析仪的合适位置，用于获取样本盒30中的采便器上的条码信息。
优选地，全自动便隐血检测分析仪还包括：回收装置，图中未示出，其位于废料支撑平台71的末端，用于回收样本盒30，避免样本盒30随意排出，污染环境。
优选地，全自动便隐血检测分析仪还包括：整机外壳104，包围进料链条10、主传送链条20、进料链条主动轮11、主传送链条主动轮21和夹持装置40。
优选地，全自动便隐血检测分析仪还包括：进料口101，设置在整机外壳104上，进料口101与进料链条10连通。
优选地，全自动便隐血检测分析仪还包括：保护盖102，设置在整机外壳104上并位于进料口101处。
优选地，全自动便隐血检测分析仪还包括：凸缘，设置在废料支撑平台71上方的整机外壳104的一侧或两侧的，图中未示出，凸缘能够和排出的样本盒30实现线面接触，防止样本盒30在排出阶段发生旋转。
本发明中，整机外壳104内设有感知样本盒30在进料链条10中的位置的第一传感器81， 以进行进料保护，防止夹手，整机外壳104内设有第二传感器82，用于检测样本盒30在主传送链条20中的位置，用于确定是否进行转送，或者拉杆50是否动作，整机外壳104内设有第三传感器83，用于在下压装置90下压时检测样本盒30在主传送链条20中的位置，整机外壳104内设有第四传感器84，用于在拍照时检测样本盒30在主传送链条20中的位置，整机外壳104内设有第五传感器85，用于在出料时检测样本盒30在主传送链条20中的位置；转送装置在样本盒到来之前在进料链条10的内部，即已经伸入到了进料链条10中，当样本盒30被转送至主传送链条20之后，转送装置需要再次回到进料链条10中，此时感应装置，即第二传感器82感应到这一状态，进料链条10暂停运动，转送装置再次回到进料链条10中，进料链条10重新启动。
患者采集便样后，便样被封闭在样本盒30的采便器中，检测时，采便器在密封状态被下压，被位于样本盒30底部采便器之下的尖刺刺破使便样稀释液流出，而且由于采便器一直在夹持装置40的配合下进行传送，可以更加有效地防止采便器内带有便样的稀释液流出，并且样本盒30完全密封，避免污染周围环境；此检测分析仪不需要现有技术中的机械探头吸取滴加样本，所以不存在交叉感染的风险。同时，此检测分析仪利用步进电机转速过低时会产生振动的缺点，可以不需要人工摇匀，实现便样和稀释液的混合。该检测分析仪可以自动完成检测并生成检测结果，检测效率大幅提高，而且可以将医生从传统的手工检测方法中解放出来，提高其感官舒适度。
本发明可以实现多个样本盒的连续检测，精确定位，样本盒不会发生翻倒、侧翻等问题，而且能准确下压样本盒，便样稀释液和试纸条反应，完成检测。同时，该分析仪利用了步进电机转速过低时会产生振动的缺点，实现对样本盒的摇动，节约了人力，提高了效率。该分析仪设置了保护盖，在开盖进样的时候，进料链条停机，对检验员进行保护，避免夹手。同时，整机占地面积更小，可以使用PLC控制整机，也可以用集成电路板控制整机。进料链条和主传送链条独立运动，互不影响，各部件流水作业，实现连续检测，提高检验效率；主传送链条速度可控可调，下压样本盒到图像采集检测结果之间的时间精准。
以上所述仅为本发明示意性的具体实施方式，并非用以限定本发明的范围。为本发明的各组成部分在不冲突的条件下可以相互组合，任何本领域的技术人员，在不脱离本发明的构思和原则的前提下所作出的等同变化与修改，均应属于本发明保护的范围。
