Description

一种检测样本分析仪吸样的方法及装置 技术领域
本发明涉及血样检测技术领域，尤其涉及一种检测样本分析仪吸样的方法及装置。
 背景技术
近年来，我国的检验医学事业有着飞速的发展，各种各样的血液分析仪在国内迅速普及，血细胞分析仪开始逐步取代镜检成为进行血常规分析的重要手段，不但提高了检验结果的效率，也给临床提供更多可靠地试验指标，对疾病的诊断和鉴别起到重要作用。血液细胞分析仪，故名思议，是吸取血样进行分析的仪器，所以要保证分析结果是否准确，第一步就是保证仪器正常从盛液血样的试管内正常吸取血样。
目前只有小部分的血液细胞分析仪提供有检测吸样有无功能，并且大部分采用的是光电传感器，通过检测经过传感器的光电信号的变化来判断是否吸取样本或者吸取样本正常。CN 107687963 A专利采用的就是这种方式，如图1所示，采样注射器下来，吸取足够多的样本，使样本至少超过透光管路上设置的光电传感器组件的位置，然后通过根据传感器反馈的检测信号来判断吸样是否正常。
 技术问题
但是这种方法有它的局限性，如图1所示，吸样时，采样注射器下拉，在负压作用下，样本被吸入采样针，然后经过光电传感器的透明管路。但是由于采样针采用的是不锈钢材质，所以它不透光，如果要使光电传感器起作用，样本液面一定要拉至透明管路，超过传感器位置。目前国内的穿刺采样针一般容积是30ul，如果要拉至光电传感器位置至少需要40ul，但是一般的检测模式血常规五分类加CRP或和SAA的血样都不需要超过30ul，所以这种方式除非用在耗血量比较大的综合性仪器上，否则很难触发光电传感器型号。
因此，如何提供一种检测样本分析仪吸样的方法和时序调度方法，以降低仪器成本及提高工作效率成为亟待解决的技术问题。
 技术解决方案
本发明要解决的技术问题在于如何提供一种检测样本分析仪吸样的方法及装置，以降低仪器成本及提高工作效率。

需要说明的是，与现有技术相比，本发明实施例通过将采样针移动到检测池，吐出头段的血，通过分析仪内只带的检测装置获取当前检测池内的液体检测值；判断检测值是否属于预设范围值内；若检测值处于预设范围值内，则样本分析仪执行检测时序。本发明不会增加仪器成本；通过样本分析仪本身自带的部件检测仪器是否正常吸取样本，及时做出判断，调整调用的测试时序，节约不必要的动作和试剂消耗，提高工作效率。
具体的，如图2所示，包括:S101.采样针在分析仪中的进样组件的移动下进入wbc池，吐出头段的血;S102.对血红蛋白浓度检测装置下发采集指令，读取当前wbc池内的液体电压信号AD值；S103.判断AD值是否属于预设范围内；S104.若AD值处于预设范围内，则样本分析仪执行检测时序。本发明不会增加仪器成本；血红蛋白浓度检测装置本身属于现有分析仪只带的装置，通过检测到仪器是否正常吸取样本，及时做出判断，调整调用的测试时序，节约不必要的动作和试剂消耗，提高工作效率。

可选地，若检测值超出预设范围值内，则样本分析仪调用清洗时序，通过清洗时序，清洗采样针内外壁和检测池，使采样针和检测池恢复至检测前的准备状态。

可选地，若第二次的检测值再次超出预设范围值内，则样本分析仪调用清洗时序，样本分析仪界面跳出故障提示框，终止检测时序操作。
可选地，检测值为AD值，预设范围值为AD预设范围值，检测池为wbc池，AD值通过样本分析仪中的血红蛋白浓度检测装置采集。
可选地，AD预设范围值为3100~3350。
如图3所示，本发明实施例公开了一种检测样本分析仪吸样的装置，包括：采样模块101，用于将采样针移动到样本池中，采集样本池内的样本；进样模块102，用于将采样针移动到检测池，吐出头段的血；获取模块103，用于获取当前检测池内的检测值；判断模块104，用于根据获取的检测值判断检测值是否属于预设范围值内；检测模块105，用于当检测值处于预设范围值内，则样本分析仪执行检测时序。

正常仪器扔掉的血，如图4中的a,b,c,d是通过拭子内部回收，在与拭子组件相连的废液模块的负压作用收集和排出。
本申请提供的检测仪器是否正常吸样的办法是通过把头段血分在wbc池，而不是扔在拭子内部，然后通过仪器本身带有的检测血红蛋白浓度的装置测试此时的本底电压判断是否在预设定的范围内来判断吸样是否正常。
下面以具体的实施方式对本申请进行详细说明。
如图5所示，比色法测试血红蛋白浓度，在检测池的一端让LED光管发出中心波长525nm的光照射检测池内的溶液，在另外一端通过光电管接收投射光，然后光信号转化成电压信号，通过与检测池最开始（最开始检测池只有稀释液，透射光信号最强）测试的本底电压信号进行对比，计算得到样本血红蛋白的浓度。
图6是本实施例公开的检测和时序调用流程图。
AD值的范围是通过多次实验得出的，图7是不吐头段血测试的电压；图8是吐1ul头段血测试的电压；图9是吐2ul头段血测试的电压；图10是吐3ul头段血测试的电压；图11是吐4ul头段血测试的电压。
结合测试数据，同时考虑到采集电压是在250ms内瞬时完成，并且信号采集中仪器电机注射器是一直在工作，所以存在个别仪器的振动导致液面波动从而电压AD值的波动，同时参考每次分血量会有略微的偏差，于是设定：AD值在3100~3350内，代表分血正常，即仪器吸样正常。当然本申请实施例只是提供一种方式，采用更高精度测检测装置可以获取更精准的AD值。
工作原理：与现有技术相比，本发明实施例中，采样针在分析仪中的进样组件的移动下进入wbc池，吐出头段的血；对血红蛋白浓度检测装置下发采集指令，读取当前wbc池内的液体电压信号AD值；判断AD值是否属于预设范围内；若AD值处于预设范围内，则样本分析仪执行检测时序。本发明不会增加仪器成本；通过检测到仪器是否正常吸取样本，及时做出判断，调整调用的测试时序，节约不必要的动作和试剂消耗，提高工作效率。
另一个实施例中，可以将头段血吐入crp计数池内，通过样本分析仪中的crp检测装置检测crp池内的AD值，判断该AD值是否属于预设范围内；若该AD值处于预设范围内，则样本分析仪执行检测时序，即通过时序命令，将采样针内的样本依次注入crp池、wbc池和diff分类池内进行检测。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。

  4. 根据权利要求3所述的检测样本分析仪吸样的方法，其特征在于，当完成所述清洗时序后，再次进行步骤a到步骤e的动作。
  5. 根据权利要求4所述的检测样本分析仪吸样的方法，其特征在于，若第二次的检测值再次超出预设范围值内，则样本分析仪调用清洗时序，样本分析仪界面跳出故障提示框，终止检测时序操作。
  6. 根据权利要求1-5任意一项所述的检测样本分析仪吸样的方法，其特征在于，所述检测值为AD值，所述预设范围值为AD预设范围值，所述检测池为wbc池，所述AD值通过样本分析仪中的血红蛋白浓度检测装置采集。
  7. 根据权利要求6所述的检测样本分析仪吸样的方法，其特征在于，所述AD预设范围值为3100~3350。
  8. 一种检测样本分析仪吸样的装置，其特征在于，包括
    采样模块，用于将采样针移动到样本池中，采集样本池内的样本；
    进样模块，用于将所述采样针移动到检测池，吐出头段的血；
    获取模块，用于获取当前检测池内的检测值；
    判断模块，用于根据获取的检测值判断检测值是否属于预设范围值内；
    检测模块，用于当检测值处于预设范围值内，样本分析仪执行检测时序。
  9. 根据权利要求8所述的检测样本分析仪吸样的装置，其特征在于，还包括清洗模块，用于当检测值超出预设范围值内时，对采样针内外壁和检测池进行清洗，使采样针和检测池恢复至检测前的准备状态。
  10. 根据权利要求9所述的检测样本分析仪吸样的装置，其特征在于，还包括调用模块，用于当采样针和检测池恢复至检测前的准备状态后，依次调用采样模块、进样模块、获取模块、判断模块和检测模块进行工作，若第二次的检测值再次超出预设范围值内，则样本分析仪再次调用清洗模块工作，并且样本分析仪界面跳出故障提示框，终止检测时序操作。
