发明内容
[0003] 本发明所要解决的技术问题是, 针对现有技术不足, 提供一种方便试纸或试剂储 存, 方便测试条存储、 传递, 且保证传递过程中测试面朝上, 不易出现翻转、 卷绕及偏移等 状况的用于全自动干化学分析仪的多项目化学测试条及其存放盒。
[0004] 为解决上述技术问题, 本发明所采用的第一种技术方案是: 一种用于全自动干化学 分析仪的测试条, 包括一测试槽,该测试槽的内底面设有若干个用于架空多项目化学反应试 纸的凸出物; 一多项目化学反应试纸嵌设于该测试槽内且搁置于该凸出物上; 该测试槽的一 端或两端设有第一导向凹槽或导向凸筋。
[0005] 上述方案的凸出物为长方体状的肋条或圆柱体状的圆台或其它本领域技术人员易想 到的形状。
[0006] 本发明也可采用第二种技术方案, 其具体为: 一种用于全自动干化学分析仪的多项 目化学测试条, 其包括一测试槽,该测试槽的内部均匀分布若干反应孔, 且每一反应孔内分 别盛放不同的化学反应试剂; 该测试槽的一端或两端设有第一导向凹槽或导向凸筋。
[0007] 该反应孔为圆形或方形或其它本领域技术人员易想到的形状。 该反应孔的孔底为平 面或凹面。
[0008] 本发明还提供了一种用于存放上述全自动干化学分析仪测试条的存放盒, 该存放盒 的侧板内侧设有与测试条的第一导向凹槽或导向凸筋配合的第二导向凸筋或导向凹槽, 该存 放盒一面的靠近底部处设有一测试条出口。
[0009] 上述方案的存放盒可包括一外盒及一内屉, 该内屉的侧板内侧设有所述第二导向凸 筋或导向凹槽, 该外盒的一端设有一开口, 内屉从该开口嵌入外盒中, 两者嵌合之后形成所 述测试条出口, 使测试条能从内屉横向推出。 该外盒开口的相对端开设有方便内屉推出的穿 孔。 该内屉上与外盒开口相配合的一端设有方便测试条推出的开口槽。
[0010] 与现有技术相比, 本发明所具有的有益效果为: 本发明将多项目反应试纸或试剂放 置于测试槽内, 方便储存与应用, 储存时, 将所有测试条按测试面朝上层层叠置的方式放 置, 使用时, 就可保证其测试面朝上, 且由于测试槽的加入, 使得测试条整体重量增加, 因 而传送过程中不易出现翻转、 卷绕及偏移等状况, 加样时, 该测试槽还可承载多余的标本 液, 使其不致直接流到工作台上, 污染工作环境。 本发明进一步将测试条储存于存放盒中, 使测试条方便储存, 且方便自动化操作。
