Description

一种集成化全内反射微流控芯片检测一体机使用方法
技术领域
本发明涉及一种体外诊断一体机的使用方法,更为具体地讲是属于医疗设备体外诊断领域的一种集成化全内反射微流控芯片检测一体机使用方法。
背景技术
全内反射荧光显微术是近年来新兴的一种光学成像技术,它利用全内反射产生的渐逝场来照明样品,从而致使在百纳米级厚的光学薄层内的荧光团受到激发,荧光成像的信噪比很高。这种方法的成像装置简单,极易和其它成像技术、探测技术相结合。目前已成功的实现 100 nm甚至更低的空间分辨率。而目前微流控芯片得到了迅速发展,而今天阻碍微流控技术发展的瓶颈仍然是应用方面的问题。全内反射光学检测技术就是一项符合与微流控芯片集成的光学检测技术。但是,目前将两者集成的一体机还比较少见,缺乏两者技术的集成检测设备。
为了对癌症及心脑血管疾病,以及多种重大恶性疾病的多种蛋白因子的一次性检测诊断,需要一种集成化全内反射微流控芯片检测一体机和使用方法。
发明内容
本发明的目的在于克服现有技术的不足,提供一种集成化全内反射微流控芯片检测一体机使用方法。
本发明的目的是这样实现的:一种集成化全内反射微流控芯片检测一体机使用方法,集成化全内反射微流控芯片检测一体机,由主机箱、控制箱和处理显示器组成,其特征在于:主机箱体竖直朝前的一面有开口,开口处安装有门,背侧壁有一个夹层空腔;箱体内部被隔板分为上下两层,下层箱内安装有倒置显微镜,安置倒置显微镜是满足一机多用目的,既能够用全内反射检测,又能够用倒置显微镜检测。倒置显微镜镜头上方对着观察窗;观察窗上方的隔板的上面安装有样品台;在样品台左右两侧对应安装有2个光导纤维激发光源,在2个光导纤维激发光源背后的箱壁上,各安装有1个入射光角度校准标尺。这样设计能够快速调校入射光角度,快速进行全反射检测。样品台上固定放置检测芯片,检测芯片正上方有全内反射光接收器。在上层箱室的背侧箱体壁上安装有竖轨,在竖轨上还水平安装有横轨,横轨与竖轨十字交叉相互垂直;全内反射光接收器通过万向转头与横臂连接,横臂固定在竖轨或横轨上。这样设计能够满足全内反射光接收器在竖轨上垂直上下移动和固定;还能够满足全内反射光接收器在横轨上左右移动和固定;还能通过万向转头扭转一定角度,保证能够快速调整好位置,使全内反射检测的顺利进行。在上层箱室的背侧箱体壁上,还加工安装有连体的加湿器和湿度感应器和湿度感应器控制风扇,以保障了活细胞检测所需要的湿度的恒定。在主机箱顶部加工安装有空气净化装置通过空气净化通风过滤孔与内部箱室相通。在主机箱顶部加工安装有空气净化装置与箱室相通,保障了监测区域的清洁度要求。主机箱体右侧是控制箱,与主机箱体相连。处理显示器放在控制箱的台面上。控制箱内部安装有标准气瓶、加样器、冷热压缩机。处理显示器与主机箱体内的倒置显微镜、全内反射光接收器线路相连,还与控制箱内的加样器、冷热压缩机线路相连。处理显示器能够控制这些装置。冷热压缩机通过冷热风管与夹层空腔相连;夹层空腔通过过滤孔与空气净化装置相连。
所述使用方法如下。

第二步,打开透明门将检测芯片放在样品台上,连接检测芯片与各个导管的接口;依据检测芯片上的检测区域位置,调整移动样品台将检测区域位置调整到观察窗,固定。因为检测用的微流控芯片需要连接众多导管,而且接头都是毛细管,移动容易使接头脱落或堵塞,所以采取固定样品台和检测芯片的设计。开启控制箱电源,打开标准气瓶调整所需二氧化碳的压力流量,开启冷热压缩机,调整温度。
第三步,观察处理显示器的温度和湿度到稳定要求后,根据检测芯的通道形状,选择左右2个光导纤维激发光源的其中一个,开启光源,依据该光导纤维激发光源对面箱体壁上的入射光角度校准标尺,调整光导纤维激发光源的入射角;角度合适后,通过竖轨调整全内反射光接收器高度,通过横轨调整全内反射光接收器左右位置;通过横臂调整全内反射光接收器前后位置;通过万向转头调整全内反射光接收器角度;最后固定全内反射光接收器,进行全内反射试样检测。由于采取固定样品台和检测芯片的设计,所以调整光路,对准监测区域的工作均由激发光路和接收器来完成。处理显示器控制测试参数和采集数据。
第四步,检测芯片上有多个检测区域位置时,重复第三步操作。
第五步,关闭光导纤维激发光源,打开倒置显微镜电源,进行常规相差显微镜检测或荧光显微镜检测,处理显示器控制参数和采集数据;如不需要常规相差显微镜检测或荧光显微镜检测,直接从第四步到第六步。
第六步,先关闭全内反射光接收器电源和倒置显微镜电源,取走检测芯片,依次关闭加湿器和湿度感应器和湿度感应器控制风扇、冷热压缩机的电源,取走加湿器中的水。最后关闭空气净化装置,关闭主机箱和处理显示器电源。顺序要求是保障一体机箱体的清洁和不受污染,同时,取走水,保持内部干燥,维护装置部件,有利于保养设备。
进一步的,所述湿度感应器控制风扇与夹层空腔相通,保障了箱室的温度均匀与恒定,湿度的均匀与恒定。
进一步的,所述主机箱体是由透明的、保温材料加工的密闭箱体;所述开口处安装有门是透明和密闭的保温门。这样保证了箱内的温度、湿度的均匀与恒定。
进一步的,所述倒置显微镜是倒置荧光显微镜,或倒置相差显微镜,这样满足不同样本的检测需要。所述控制箱是独立箱体,能够与主机箱扣合联接或拆分,控制箱的高度是主机箱体高度的1/2以上。
本发明相对于现有技术具有如下优点。
1. 能够快速地调整全内反射入射角,对检测芯片的适应性强,能够使用不同种类,和不同设计的微流控芯片。
2. 能够用全内反射技术检测又能用常规显微镜检测,实现一机多用,一机联测多种不同的蛋白因子的要求。
3. 通过全内反射检测技术、微流控芯片技术两种技术结合与一体机的整合,实现了检测区域的温度均匀与恒定,湿度的均匀与恒定。
