Description

一种样本位置获取方法、样本分析系统及计算机存储介质 技术领域
本申请涉及样本分析领域,涉及但不限于一种样本位置获取方法、样本分析系统及计算机存储介质。
背景技术
随着医疗技术的飞速发展,样本检测的需求也越来越高。利用单个检测设备分别进行样本检测已经满足不了样本检测需求,因此为了满足样本检测需求和减少检测时间,出现了流水线来测试样本的样本分析系统。在利用样本分析系统对样本进行检测后,检验医生检查软件系统上的结果,对异常结果进行确认,部分样本需要查询试管在样本分析系统中的位置,以找到样本后查看样本性状,或者对样本进行换机、其它手工分析处理等操作。
目前,通常利用条码来区分各个样本,但条码扫描仪每次只能扫描一个试管,且只能安装在样本检测仪器上固定的位置。因此,医生查询试管在流水线的位置时,只能根据条码扫描仪上报的信息,大致推断某试管所在的区域,而不能精确定位试管是否在轨道上,或者是否在样本分析仪中,费时费力且处理效率低下。

在以下的描述中,涉及到“一些实施例”,其描述了所有可能实施例的子集,但是可以理解,“一些实施例”可以是所有可能实施例的相同子集或不同子集,并且可以在不冲突的情况下相互结合。
如果申请文件中出现“第一/第二”的类似描述则增加以下的说明,在 以下的描述中,所涉及的术语“第一\第二\第三”仅仅是是区别类似的对象,不代表针对对象的特定排序,可以理解地,“第一\第二\第三”在允许的情况下可以互换特定的顺序或先后次序,以使这里描述的本申请实施例能够以除了在这里图示或描述的以外的顺序实施。
除非另有定义,本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述本申请实施例的目的,不是旨在限制本申请。
为了更好地理解本申请实施例,首先对相关技术中的流水线(样本分析系统)组成结构和工作过程进行说明。
图1为相关技术中流水线的组成结构示意图,如图1所示,在流水线中至少包括装载台101、体外诊断(In Vitro Diagnostic,IVD)仪器102、轨道103和卸载台104。
以下结合图1对基于流水线进行样本分析的工作工程进行说明,该过程包括以下步骤:
步骤S001,血液样本(一般会配备条码)由装载台进行装载。
在本申请实施例中,承载样本的容器(例如试管或者载玻片)上贴有条码,便于仪器识别样本,并通过条码查询样本需要分析的项目。
步骤S002,在软件调度下,根据某样本需要分析的项目,试管(样本)通过轨道送入各台IVD仪器进行样本分析。
步骤S003,所有的IVD仪器吸样完毕后,试管(样本)通过轨道送入卸载台,随后进行自动或手动归档处理。
步骤S004,IVD仪器完成分析并上报结果到软件系统
步骤S005,检验医生检查软件系统上的结果,对异常结果进行确认。
部分样本(例如存在异常结果的样本)需要查询试管在流水线上的位置,找到样本后查看样本性状,或者对样本进行换机、其它手工分析处理 等操作。
目前,一般使用条码来区分样本,但条码扫描仪每次只能扫描一个试管,且只能安装在IVD仪器上固定的位置。因此,医生查询试管在流水线的位置时,只能根据条码扫描仪上报的信息,大致推断某试管所在的区域,而不能精确定位试管是否在轨道上,或者是否在IVD设备中。
基于此,本申请实施例提供一种样本位置获取方法,应用于样本分析系统,所述样本分析系统至少包括多台样本分析仪、控制装置、连接多台样本分析仪的轨道、驱动试管架在轨道上运输的传送装置及至少一个图像采集装置。图2为本申请实施例样本位置获取方法的一种实现流程示意图,如图2所示,所述方法包括:
步骤S201,传送装置通过样本分析系统的轨道运输至少一试管架。
这里,试管架上承载至少一装有待测样本的试管,每个试管上贴覆有条码,通过扫描该条码可以获取到试装中的待测样本对应的用户标识、检测项目等信息。并且试管架上也具有试管架的标识。
步骤S202,获取图像采集装置针对样本分析系统采集到的待处理图像和所述待处理图像的采集时间。
这里,步骤S202可以是样本分析系统中的控制装置实现的,该控制装置可以是台式计算机、一体机、桌面电脑等终端设备。在本申请实施例提供的样本分析系统中,除了常规的样本分析仪、前处理模块、后处理模块以及输送轨道,控制装置之外,还可以包括图像采集装置,其中该图像采集装置可以是摄像头,所述摄像头可以是单摄像头还可以是双摄像头或者多摄像头,并且该摄像头可以是标准摄像头还可以是广角摄像头等。在本申请实施例中,图像采集装置可以是一个,也可以是多个,当是一个图像采集装置时,该图像采集装置可以设置于样本分析系统的中间位置,能够对样本分析系统的各个部分都能够拍摄到,当图像采集装置有多个时,可 以在样本分析系统中等距离或不等距离进行设置。
在利用图像采集装置进行图像采集,也即利用图像采集装置对样本分析系统进行图像拍摄时,可以根据采集到的待处理图像的属性信息得到待处理图像的采集时间。
步骤S203,对所述待处理图像进行识别,获取所述待处理图像中的第一样本标识和第一样本标识对应的位置信息。
这里,步骤S203在实现时,可以按照预设的图像识别算法对待处理图像进行识别,从而得到待处理图像中的第一样本标识,在本申请实施例中,第一样本标识可以是容置第一样本的容器上贴覆的条码编号。第一样本标识对应的位置信息可以利用距离第一样本最近的样本分析仪标识来表征,样本分析仪标识可以是样本分析仪的编号,该编号可以工作人员人为给样本分析仪进行编号得到的,例如可以是001,还可以是由样本分析仪的型号加序号得到的,例如可以是BC-5380-1。举例来说,第一样本标识的位置信息可以是在编号为001和编号为002的两个样本分析仪之间的传输轨道上。
步骤S204,建立所述采集时间、所述第一样本标识和所述第一样本标识对应的位置信息之间的对应关系,保存所述对应关系。
这里,建立所述采集时间、所述第一样本标识和所述第一样本标识对应的位置信息之间的对应关系,不仅能够根据样本标识,获取样本的位置,还能够根据采集时间获取样本的行进路线,以能够全面的获取样本的检测信息。
在建立了上述对应关系后,可以存储至控制装置自身的存储空间,以便于工作人员通过控制装置查询样本的位置信息,在一些实施例中,还可以将该对应关系发送至数据管理设备,例如可以是LIS系统中的数据管理终端,以使得可以通过数据管理终端查询样本的位置信息。
在本申请实施例提供的样本位置获取方法中,在样本检测过程中需要 确定样本的位置信息时,可以首先获取图像采集装置针对样本分析系统采集到的待处理图像和所述待处理图像的采集时间;并进一步对所述待处理图像进行识别,获取所述待处理图像中的第一样本标识和第一样本标识对应的位置信息;建立所述采集时间、所述第一样本标识和所述第一样本标识对应的位置信息之间的对应关系,保存所述对应关系,这样就能够通过图像识别的方式获取样本的位置信息,进而在检验人员需要查找某个样本时能够得到该样本相对精确的位置信息,从而实现更有目的性的拿取,提高样本处理效率。
在本申请实施例中,步骤S202“获取图像采集装置针对样本分析系统采集到的待处理图像和所述待处理图像的采集时间”可以有多种实现方式,例如,可以是仅对试管或试管架进行拍摄以获取待处理图像,也就是哪里有试管或者试管架则拍摄哪里,获取到的待处理图像可以是利用图像采集装置的拍照模式采集到的多张静态图像,还可以是利用图像采集装置的视频录制模式采集到的视频中的各帧图像。
在实际实现过程中,步骤S202可以通过以下步骤实现,以实现通过针对试管或试管架的拍摄获取待处理图像:
步骤S2021a,控制图像采集装置针对包含试管架的区域进行拍摄,以获取待处理图像。
这里,所述待处理图像中包括待识别的试管或试管架。在本申请实施例中,图像采集装置是可以转动的,或者是可以移动的。步骤S2021a在实现时,可以是利用图像采集装置进行图像预览,得到预览图像,并确定预览图像中是否包括试管或试管架,当预览图像中包括试管或试管架时,则进行图像采集,得到待处理图像;当预览图像中不包括试管或试管架时,则暂不进行图像采集,此时可以调整图像采集装置的角度或者调整图像采集装置的焦距等参数,直至预览图像中包括试管或试管架时,再进行图像 采集以获取待处理图像。
步骤S2022a,将所述图像采集装置的拍摄时刻确定为所述待处理图像的采集时间。
这里,将图像采集装置拍摄待处理图像的拍摄时刻确定为待处理图像的采集时间。
通过上述的步骤S2021a至步骤S2022a能够保证采集到各个待处理图像是包括试管或者试管架的,这样能够避免对不包括试管或试管架的图像进行识别,降低了计算量,从而提高样本位置获取的效率。
在实际实现过程中,步骤S202的实现方式还根据样本分析系统中图像采集装置的不同个数而有所不同。其中,当所述图像采集装置的个数为一个时,步骤S202可以通过以下步骤实现:
步骤S2021b,控制所述图像采集装置按照预设的角速度转动。
当图像采集装置只有一个时,需要图像采集装置能够转动到不同的角度进行拍摄,才能保证图像采集装置能够拍摄到处于整个样本分析系统中各个部分的试管或试管架,因此在该步骤中,控制装置控制图像采集装置按照预设的角速度转动,进一步地,可以是图像采集装置从预设的起始位置按照该角速度匀速转动,直至达到预设的终止位置,然后可以是再归位到起始位置进行下一次扫描拍摄,在一些实施例中,还可以是达到终止位置后,再按照该角速度反方向转动,直至达到起始位置。
步骤S2022b,控制所述图像采集装置在转动过程中每间隔预设时长采集一张图像,得到各个待处理图像。
这里,在转动过程中,图像采集装置可以每间隔一定时长采集一张图像,例如可以是每间隔1秒采集一张图像,从而得到各个待处理图像。
步骤S2023b,将图像采集装置拍摄各个待处理图像的时间确定为对应的采集时间。
当所述图像采集装置的个数为至少两个时,步骤S202可以通过以下步骤实现:
步骤S2021c,控制所述至少两个图像采集装置同时采集图像。
这里,步骤S2021c在实现时,可以首先调整至少两个图像采集装置的焦距,以保证利用样本分析系统中设置的多个图像采集装置能够拍摄到样本分析系统完整的图像,进而再控制至少两个图像采集装置同时采集图像。
步骤S2022c,将所述至少两个图像采集装置采集到的图像进行图像拼接,得到待处理图像。
这里,步骤S2022c在实现时,可以根据图像融合算法,将至少两个图像采集装置采集到的图像进行图像拼接,从而得到待处理图像,此时得到的待处理图像是样本分析系统的完整图像。
步骤S2023c,将图像采集装置拍摄各个待处理图像的时间确定为对应的采集时间。
通过上述的步骤S2021c至步骤S2023c,得到的待处理图像是样本分析系统的完整图像,因此在后续对待处理图像进行识别,能够获取同一时刻处于样本分析系统中各个位置的样本的位置信息。
在一些实施例中,步骤S203“对所述待处理图像进行识别,获取所述待处理图像中的第一样本标识和第一样本标识对应的位置信息”可以通过下述的步骤S2031至步骤S2034,包括:
步骤S2031,获取所述待处理图像中的第一目标图像区域。
这里,所述第一目标图像区域中包括待识别的试管或试管架。步骤S2031在实现时,可以提取待处理图像的图像特征,进而根据提取出的图像特征确定出包括试管或试管架的第一目标图像区域。
步骤S2032,对第一目标图像区域进行识别,获取所述第一目标图像区 域对应的第一样本标识。
这里,由于第一目标图像区域中包括待识别的试管或试管架,并且试管或试管架上贴有条码,因此对第一目标图像区域进行识别,进一步地,可以是识别第一目标图像区域中的数字,从而获取到第一目标图像区域中的第一样本标识。在本申请实施例中,识别出的第一样本标识可以是一个,也可以是多个。
步骤S2033,基于所述第一目标图像区域,确定第二目标图像区域。
这里,所述第二目标图像区域中至少包括与所述待识别的试管或试管架之间的距离满足预设距离条件的样本分析仪以及待识别的试管或试管架。进一步地,该预设距离条件可以是距离待识别的试管或试管架最近。也就是说第二目标图像区域中包括待识别的试管或试管架以及包括距离该试管或试管架最近的样本分析仪。
步骤S2034,对所述第二目标图像区域进行识别,获取所述第一样本标识对应的位置信息。
这里,步骤S2034可以通过下述的步骤S341至步骤S344实现:
步骤S341,对所述第二目标图像区域进行图像识别,获取所述样本分析仪的标识信息。
这里,由于在步骤S2302中已经通过对第一目标图像区域进行识别,得到了第一样本标识,因此在步骤S341中,对第二目标图像区域进行图像识别时,只需要对样本分析仪的标识进行识别即可。在本申请实施例中,样本分析仪的标识信息可以是样本分析仪的出厂编号,还可以是样本分析仪的型号,如果样本分析系统中如果包括多个相同的样本分析仪,例如,如图3A所示,在该样本分析系统中包括两台血液分析仪301和302、一台推片机303、一台阅片机304,并且两台血液分析仪的型号是相同的,都是BC-6000,那么为了区分这两个血液分析仪,可以在这两个血液分析仪上贴 覆编号标签,此时样本分析仪的标识信息可以用型号加编号的方式表征,例如血液分析仪301的标识信息可以是BC-6000-1,血液分析仪302的标识信息可以是BC-6000-2。
步骤S342,基于所述样本分析仪的标识信息确定所述第一样本标识所对应的轨道信息。
这里,在本申请实施例中,为了更准确地表示样本位置,可以将传输试管或试管架的轨道进行划分,并进行标识,在实现时,可以利用样本分析仪的标识对轨道进行标识,图3B为本申请实施例根据样本分析仪划分轨道的示意图,如图3B所示,在该样本分析系统中包括装载台311、血液分析仪312、血液分析仪313、CRP分析仪314、推片机315、卸载平台316,那么对应地,可以将轨道划分为装载台轨道321、分析仪轨道一期322、分析仪轨道二期323、CRP轨道324、推片机轨道325和卸载台轨道326。
步骤S343,确定所述样本分析仪与所述待识别试管或试管架的距离信息。
这里,由于试管或试管架的实际大小是已知的,例如试管的长度是15厘米,待处理图像中试管的长度为4.5厘米,并且能够确定出样本分析仪与待识别试管或试管架在待处理图像中的距离,例如为15厘米,那么可以确定出该样本分析仪与待识别试管或试管架之间的实际距离为15/4.5*15=50厘米。
步骤S344,基于所述轨道信息和距离信息,确定所述第一样本标识对应的位置信息。
这里,在确定出轨道信息和距离信息后,可以确定第一样本标识对应的位置信息,例如可以是位于分析仪轨道一期50厘米处。
通过上述的步骤S2031至步骤S2034,即可确定出第一样本标识对应的位置信息,从而能够使得工作人员能够根据位置信息快速、准确地查找对 应的样本。
在一些实施例中,为了获取到更全面的信息,除了要获取样本的位置之外,还需要获取样本的运动方向,此时可以根据以下步骤确定样本的运动方向:
步骤S301,获取预设时长内获取到的各个待处理图像。
这里,预设时长可以用户设置的,还可以是系统默认设置的,例如预设时长可以是15分钟,需要说明的是,预设时长内获取到的各个待处理图像,是以当前时刻为结束时间的一段时长内获取到的各个待处理图像,例如当前时刻为11点,预设时长内获取到的各个待处理图像为10点45到11点之间获取到的各个待处理图像。
步骤S302,分别对各个待处理图像进行识别,得到各个待处理图像中的第一样本标识和第一样本标识对应的位置信息。
步骤S303,基于各个位置信息确定承载第一样本的试管或试管架的运动方向。
这里,在确定出第一样本标识对应的多个位置信息后,可以根据多个位置信息以及位置信息对应的时间信息,确定承载第一样本的试管或试管架的运动方向。
举例来说,确定出10点50分承载第一样本的试管的位置信息为分析仪轨道一期50厘米,确定出11点承载第一样本的试管的位置信息为CPR轨道20厘米处,由于CRP轨道比分析仪轨道一期更远离装载台,那么可以认为此时承载第一样本的试管是在向下一个样本分析仪移动。
这样,在确定出承载第一样本的试管或试管架的运动方向之后,能够确定第一样本是在向下一个样本分析仪移动还是在沿着轨道返回,能够使得工作人员根据样本的运动方向更准确地确定测试进度。
在本申请实施例中,样本分析系统在工作时,会在输入区对样本进行自动扫码和样本分拣等。对样本进行自动扫码能够识别样本的样本标识,进一步地,在输入区可以通过样本识别模块(或输入区外的样本识别模块)扫描盛放样本的容器,例如试管上的条码,从而获取到样本标识。在本申请实施例中样本标识可以是条码编号。
在一些实施例中,识别样本的样本标识还可以不仅限于在输入区,也可为多个,因为样本识别模块还可以设置在样本分析系统的轨道上的一些固定位置,样本每经过一次样本识别模块可以识别一次样本标识。
由于试管上的条码一般是由检验人员人为粘贴上去的,因此粘贴的位置也不尽相同,在利用样本分析系统中的各个样本分析仪对样本进行样本分析时,试管上的条码有可能会被样本分析仪遮挡,此时在对待处理图像进行识别,往往也不能识别出样本标识,此时,可以通过如图4所示的各个步骤获取样本位置:
步骤S401,获取所述样本分析系统中未完成样本分析的未完成样本标识。
这里,未完成样本分析的样本可以是未到达卸载台的样本。在本申请实施例中,当承载样本的试管或试管架上线进行样本分析时,首先要对承载样本的试管上的条码进行扫描,以获取条码信息,并根据条码信息获取样本分析项目,进而根据获取到的样本分析项目调度到对应的样本分析仪进行样本分析,在完成所有的样本分析项目后该试管或试管架会被调度到卸载台,进行回收归档。
步骤S402,确定所述未完成样本标识中除所述第一样本标识之外的第二样本标识。
在本申请实施例中,第一样本标识为通过图像识别所识别出的样本标识,第一样本标识可以是多个不同的样本标识。因此,第二样本标识可以 是未完成样本标识中,未被图像识别所识别出的样本。
步骤S403,获取所述样本分析系统中各个样本识别模块发送的条码扫描信息。
这里,在本申请实施例提供的样本分析系统中可以包括多个样本识别模块,样本识别模块可以是条码扫描仪、射频识别(Radio Frequency Identification,RFID)等设备。每当有试管经过样本识别模块,样本识别模块会扫描试管上的条码,以得到条码扫描信息,并将条码扫描信息和扫描时间发送至控制装置。其中条码扫描信息至少包括扫描得到的样本标识。
步骤S404,基于所述条码扫描信息,确定所述第二样本标识对应的位置信息。
这里,在实际实现过程中,步骤S404可以通过以下步骤实现:
步骤S4041,获取所述第二样本标识对应的各个条码扫描信息和各个条码扫描信息对应的扫描时间。
这里,由于在样本分析系统中有多个样本识别模块,那么同一个条码会被多次扫描识别,因此每个样本标识会对应有多个条码扫描信息。在步骤S4041中,仅需要获取未被图像识别出的第二样本标识对应的各个条码扫描信息和扫描时间即可。
步骤S4042,从各个扫描时间中确定距离当前时间最近的目标扫描时间。
这里,为了确定样本当前的位置信息,需要从各个扫描时间中确定距离当前时间最近的一个扫描时间,并将该扫描时间确定为目标扫描时间。
步骤S4043,获取所述目标扫描时间对应的目标设备标识。
这里,确定出目标扫描时间对应的目标设备标识,从而能够确定在该目标扫描时间是由哪个样本识别模块对该样本进行扫描的。
步骤S4044,基于所述目标设备标识确定所述第二样本标识对应的当前 位置信息。
这里,由于每个样本识别模块的位置是固定的,在获取到目标设备标识之后,即可获取到该目标设备标识对应的样本识别模块的位置,此时可以将该样本识别模块的位置确定为第二样本标识对应的当前位置信息。
在本申请实施例中,在获取到样本的位置信息后可以便于工作人员查询,此时,所述方法还包括:
步骤S205,接收位置查询的操作指令。
其中,所述操作指令中携带有待查询样本标识,该操作指令可以是用户利用连接于控制装置的人机交互设备触发的,该人机交互设备可以是鼠标、键盘等输入设备,还可以是触控显示屏等输出设备。
步骤S206,基于所述待查询样本标识,确定所述待查询样本标识当前的位置信息。
这里,在获取到待查询样本标识后,可以通过已建立的样本标识、位置信息和采集时间之间的对应关系,确定出待查询样本标识当前的位置信息。
步骤S207,输出所述位置信息。
进一步地,步骤S207可以通过下述步骤实现:
步骤S2071,获取位置信息的输出方式。
这里,所述输出方式至少包括图形式输出和表格式输出。
步骤S2072,基于所述输出方式输出所述位置信息。
这里,当输出方式为图形式输出时,也即将待查询样本在样本分析系统中具体的位置进行图形图像输出,进一步地,可以将待查询样本进行高亮显示,以使得用户能够更加直观的看到待查询样本所在的位置;当输出方式为表格式输出时,也即将待查询样本的位置信息以表格的形式输出,在实现时可以输出距离当前时间最接近的一条记录,包括待查询样本标识、 位置信息以及时间信息。
基于上述实施例,本申请实施例再提供一种样本位置获取方法,通过视觉技术来辅助软件交互操作以获取样本位置,该方法应用于样本分析系统,图5为本申请实施例提供的样本分析系统的一种组成结构示意图,如图5所示,该样本分析系统包括:装载台501、IVD仪器502、轨道503、卸载台504和摄像头装置505。
以下结合图5,对利用该样本分析系统进行样本分析时,获取样本位置的实现过程进行说明。
步骤S701,血液样本(一般会配备条码)由装载台进行装载。
在本申请实施例中,承载样本的容器(例如试管或者载玻片)上贴有条码,便于仪器识别样本,并通过条码查询样本需要分析的项目。
步骤S702,在软件调度下,根据某样本需要分析的项目,试管(样本)通过轨道送入各台IVD仪器进行样本分析。
步骤S703,采用摄像头装置,持续拍摄并识别轨道上的试管条码。
步骤S704,根据识别结果,使用算法实时计算试管的位置。
在实际实现过程中,计算样本的位置也即确定在轨道上试管、已经进入某台IVD仪器的试管、已经重新回到轨道上的试管。
步骤S705,将试管位置信息实时上报到软件系统。
步骤S706,用户通过软件系统查询到更加精确的试管位置。
在本申请实施例中可以使用一个摄像头来进行图像采集及图像识别以确定样本(试管)的位置,也可以使用多个摄像头进行图像采集及识别,并通过算法的组合来整体计算和确定试管的精确位置。
在一些实施例中,除了使用摄像头之外,还可以辅以条码扫描仪、RFID等设备,整体计算和确定试管的精确位置。
