Description

一种生化反应试纸条管及其使用方法和试剂盒 技术领域
本发明涉及生物工程技术领域,尤其涉及一种生化反应试纸条管及其使用方 法和试剂盒。 背景技术
在常规的小型生化反应中,一般是单个的试管内设置一个腔体并放置一种溶 液, 当需要多个溶液参与反应时, 将不同试管的溶液吸取后加入其它反应试管, 将最终反应溶液放置到特定的检测设备内进行反应信号来判断反应结果。如要更 简便地判断反应结果, 人们一般使用生化试纸条对反应溶液进行信号检测, 这时 要将反应溶液吸取出来再滴加到试纸条上。 当存在一些特殊原因如试剂污染时, 试管内的溶液要求保持密闭, 不允许被吸取出来进行试纸条的滴加检测, 如炭疽 病原检测, 二恶英等项目。
自 1985 年美国 Cetus 公司用聚合酶链反应 (Polymerase Chain Reaction, PCR) 实现核酸的特异性扩增以来,这项技术就因具有高灵敏度、高特异性和高效的特 点被 广泛应用于疫病病原检测领域。 但被扩增的高浓度病原核酸序列很容易在 后续操作过 程中污染空气、 试验器具和水, 因而导致后续检测样品的假阳性结 果。因此核酸检测 的普及推广中,也需要开发封闭式检测装置与方法。 Gerdes等 (US2004/0110167)将侧流层析技术应用到核酸扩增产物的检测中, 给核酸检测 在基层应用带来了希望。为了避免在核酸侧流层析过程中产生污染, 最佳的选择 是使用装置将层析过程封闭起来。 顾家永等 (CN1888902)发明了一种全封闭式 靶核酸扩增物快速检测装置, 其结构包括外壳和内盒, 内盒中包括层析稀释液、 核酸扩增产物和层析试纸条,当外壳关闭的同时内盒中的刀片刺破稀释液管和核 酸扩增管, 两种液体混合后被导入层析 试纸条的样品垫, 实现免疫层析显色反 应。 但该装置的缺点是: 1、 装置体积大, 不适合成品的规模生产与运输; 2、 装 置中的试纸条安装复杂,不适合规模化的试纸装配生产; 3、本装置再启动使用后, 能被轻松简单而且没有痕迹地重新打开,因此只是相对地实现了核酸扩增产物的 封闭, 如果被人无意开启了反应过的装置, 扩增产物的 污染就不可避免了; 4、 该装置中只能完成单个反应液的检测, 而无法检测多个反应液, 即无法以多个反 应液的方式在一个试纸条上完成多重样品的检测。
发明专利申请 CN103529201A 中公开了一种封闭式的层析试纸检测装置, 该装置能实现完全封闭, 能完全阻断层析试纸的样品对操作人员的危害和环境 的污染。 但是该装置存在的缺点有: 1、 当溶液管管径较小时, 溶液管的管底很 难被打开; 2、 连接管内的气体不容易进入到溶液管, 致使连接管内的气体压力 将会升高; 如果连接管内的气体压力超过管外的气压, 且这压力差超过了密封结 构的承受值, 管内的气体还是会向外排泄的, 当管内有溶液时, 溶液也会在气体 的驱动下, 产生泄漏。
发明专利申请 201310157026.2、 20161014397T8、 201310511291.6 中公开 了一种通过反应试管与容纳层析试纸的密闭腔体配合从而将溶液从试管被捅破 的底部导入密闭腔体的装置。但是该装置的缺点在于它需要多个器件来组成, 还 需要额外的动作与器件来捅破反应试管的底部,且在反应试管底部捅破时由于气 压原因反应试管与密闭腔体要保持密封来防止溶液外泄,需要操作人员有适当的 操作技巧。 发明内容
