在曰常工作和生活中，通常需要检测液体中某一物质是否存在或者是否达 到一定浓度， 进而根据检测结果进行相应的处理。 例如： 通过检测水源中某一 氨基酸的浓度确定该水源的水质或被污染程度， 或者，通过检测尿液中人绒毛 膜促性腺激素 （筒称 HCG )是否存在确定该尿液的所属者是否怀孕等。
现有技术中，用于检测液体中被测物质是否存在或浓度的数字化测试笔通 常至少包括： 承载试纸的测试芯以及设置有承载测试芯的空腔的检测仪本体； 其中， 测试芯的外壳上设置有用于显示试纸测试区的测试窗口，检测仪本体中 的判断电路根据测试窗口中试纸测试区所显示颜色得出检测结果，从而通过检 测仪本体的外壳上的显示窗口将该显示结果显示给用户，以此实现了液体的检 测。
但是， 当测试芯被插入到检测仪本体后， 由于需要将液体淋到测试芯的试 纸上， 测试芯的外壳上有可能也被淋上液体， 此时， 测试芯的外壳上的液体可 能沿着测试芯外壳流动，进而通过检测仪本体的测试芯插入端口处的缝隙流入 检测仪本体的内部， 这无疑将污染到检测仪本体的内部， 而检测仪本体的内部 受到液体污染将影响其使用寿命。 发明内容

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅是本发明一部分实施例， 而不是全 部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有做出创造性 劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
现有技术中， 当测试芯被插入到检测仪本体后， 由于需要将液体淋到测试 芯的试纸上， 测试芯的外壳上有可能也被淋上液体， 此时， 测试芯的外壳上的 液体可能沿着测试芯外壳流动，进而通过检测仪本体的测试芯插入端口处的缝 隙流入检测仪本体的内部， 这无疑将污染到检测仪本体的内部， 而检测仪本体 的内部受到液体污染将影响其使用寿命。
为了避免检测过程中检测仪本体的内部受到液体污染，本发明提供了一种 基于试纸的检测装置。
如图 1所示， 一种基于试纸的检测装置， 可以包括：
承载试纸 100的测试芯 110、 设置有承载该测试芯 110的空腔的检测仪本 体 120;
其中，该测试芯 110的外壳上的第一位置处设置有在该测试芯 110被插入 到该检测仪本体 120后密封该检测仪本体 120的测试芯插入端口处的缝隙的密 封圏 111;
其中，该第一位置为该测试芯 110被插入该检测仪本体 120后与该测试芯 插入端口相对的位置。
需要说明的是，该密封圏 111可以被直接套进该测试芯 110进而进行固定， 从而使得生产操作过程较为筒单；而由于现有技术中的测试芯的形状与检测仪 本体的形状相适配， 因此， 为了保证良好的密封性， 该密封圏 111的形状与该 测试芯 110的形状相适配， 以使得该密封圏 111能够顺利穿过该测试芯 110并 固定在第一位置处。 其中， 由于该第一位置为该测试芯 110被插入该检测仪本 体 120后与该测试芯插入端口相对的位置， 因此，设置于该第一位置的该密封 圏 111可以密封该测试芯 110被插入该检测仪本体 120后该测试芯插入端口处 的缝隙。
需要说明的是， 在实际应用中， 该密封圏 111可以粘接在该测试芯 110的 外壳的第一位置处； 或者， 该测试芯 110的外壳的第一位置处设置有凹槽， 相 应的， 该密封圏 111被固定于该凹槽中， 当然， 该密封圏 111被固定在该凹槽 中后， 相对于该测试芯 110的外壳而言应该突出以保障能够密封缝隙。 本领域 技术人员可以理解的是， 上述固定方式仅仅作为示例， 并不应该构成对本发明 方案的限定。
其中， 该密封圏 111所选用的材质可以为： 橡胶或工程塑料， 当然并不局 限于此。 例如， 该密封圏 111的材质还可以为其他能够阻止液体流动的材质。
本领域技术人员可以理解的是， 该基于试纸的检测装置中， 该测试芯 110 的外壳上还可以设置有用于显示试纸测试区的测试窗口 112 以及用于将其固 定在该检测仪本体 120的空腔内的第一锁紧元件 （图 1未示出）； 而该检测仪 本体 120还可以包括：根据测试窗口 112中试纸测试区所显示颜色得出检测结 果的判断电路（图 1未示出）、 显示该检测结果的显示窗口 121、 设置在空腔 内壁上的与该第一锁紧元件相适配的第二锁紧元件、设置在外壳上的用于将固 定于该空腔内的该测试芯 110进行释放的释放元件 122等。
本发明实施例所提供的基于试纸的检测装置中，测试芯的外壳上的第一位 置处设置有在该测试芯被插入到检测仪本体后密封该检测仪本体的测试芯插 入端口处的缝隙的密封圏； 因此， 在检测过程中， 当淋到测试芯的外壳上的液 体沿着测试芯的外壳流动时，在密封圏的阻隔下， 液体将无法通过检测仪本体 的测试芯插入端口处的缝隙流入检测仪本体的内部，从而可以有效避免检测过 程中检测仪本体的内部受到液体污染的问题。 由于当测试芯被插入到检测仪本体后，通常需要将液体淋到测试芯中的试 纸上， 而液体有可能会溅到检测仪本体的外壳上， 此时， 也将导致检测仪本体 受到液体污染。 因此， 更进一步的， 为了解决上述问题， 本发明实施例还提供 一种基于试纸的检测装置。
如图 2所示， 一种基于试纸的检测装置， 可以包括：
7 载试纸 200的测试芯 210、 设置有 7 载该测试芯 210的空腔的检测仪本 体 220;
其中，该测试芯 210的外壳上的第一位置处设置有在该测试芯 210被插入 到该检测仪本体 220后密封该检测仪本体 220的测试芯插入端口处的缝隙的密 封圏 211 ; 该测试芯 210的第二位置处设置有在该测试芯 210被插入到该检测 仪本体 220后容纳该检测仪本体 220至少一部分的保护罩 212;
其中，该第一位置为该测试芯 210被插入该检测仪本体 220后与该测试芯 插入端口相对的位置；该第二位置为该第一位置与该测试芯 210的试纸插入端 口之间的一位置。
需要说明的是， 该密封圏 211可以被直接套进测试芯 210进而进行固定， 从而使得生产操作过程较为筒单；而由于现有技术中的测试芯的形状与检测仪 本体的形状相适配， 因此， 为了保证良好的密封性， 该密封圏 211的形状与该 测试芯 210的形状相适配，以使得该密封圏 211能够穿顺利过该测试芯 210并 固定在第一位置处。
其中，由于该第一位置为该测试芯 210被插入该检测仪本体 220后与该测 试芯插入端口相对的位置， 因此，设置于该第一位置的该密封圏 211可以密封 该测试芯 210被插入该检测仪本体 220后该测试芯插入端口处的缝隙。而由于 该第二位置为该第一位置与该测试芯 210 的试纸插入端口之间的一位置， 因 此，设置于该第二位置处的保护罩 212不会影响测试芯 210被插入到该检测仪 本体 220的空腔中。 其中， 需要说明的是， 该保护罩 212也可以被设置在该测 试芯 210的试纸插入端口处或者该密封圏 211所在的第一位置； 同时， 在保证 该保护罩 212能够容纳该检测仪本体 220至少一部分的前提下， 该保护罩 212 的形状并不局限于图 2所示的漏斗状， 还可以为桶状等。
需要说明的是， 在实际应用中， 该密封圏 211可以粘接在该测试芯 210的 外壳的第一位置处； 或者， 该测试芯 210的外壳的第一位置处设置有凹槽， 相 应的， 该密封圏 211被固定于该凹槽中， 当然， 该密封圏 211被固定在该凹槽 中后，相对于该测试芯 210的外壳而言应该突出以保障能够密封缝隙。同样的， 该保护罩 212的第一端可以粘接在该测试芯 210的外壳的第二位置处，且该保 护罩 212的第二端处于活动状态； 或者， 该保护罩 212的第一端以可拆卸方式 设置在该测试芯 210的外壳的第二位置处，且该保护罩 212的第二端处于活动 状态； 其中， 该保护罩 212的第二端处于活动状态具体指： 该保护罩 212的第 二端未被固定在任何元件上。 本领域技术人员可以理解的是， 上述固定方式仅 仅作为示例， 并不应该构成对本发明方案的限定。
更进一步的， 当液体被淋到试纸上后，在将该基于试纸的检测装置放置到 实验桌等承载台上来等待检测结果时， 为了防止液体滴到承载台上， 该保护罩 212 的该第二端的横截面积可以大于该第一端的横截面积， 以使得该保护罩 212能够被翻转， 以容纳该测试芯 210。 例如： 图 2所示的保护罩 212为漏斗 状， 当该测试芯 210被插入到该检测仪本体 220后， 该保护罩 212可以容纳该 检测仪本体 220的一部分，如图 3所示； 而在将该基于试纸的检测装置放置到 实验桌等承载台上来等待检测结果时， 为了防止液体滴到承载台上， 如图 4 所示， 该保护罩 212可以被翻转以容纳该测试芯 210, 从而防止液体滴到承载 台上。
其中， 该密封圏 111所选用的材质可以为： 橡胶或工程塑料， 当然并不局 限于此。 例如， 该密封圏 111的材质还可以为其他能够阻止液体流动的材质。 相应的， 该保护罩 212的材质可以选择： 橡胶、 工程塑料或聚乙烯材质， 当然 并不局限于此。 可以理解的是， 该保护罩 212可以选择具有一定柔软度的材 质， 以使得在该测试芯 210闲置时， 可以将该保护罩 212收起， 以避免占用空 间， 而在使用时， 将该保护罩 212展开即可， 同时， 保证了该保护罩 212容易 被翻转。
本领域技术人员可以理解的是， 该基于试纸的检测装置中， 该测试芯 210 的外壳上还可以设置有用于显示试纸测试区的测试窗口 213 以及用于将其固 定在该检测仪本体 220的空腔内的第一锁紧元件 （图 2未示出）； 而该检测仪 本体 220还可以包括：根据测试窗口 213中试纸测试区所显示颜色得出检测结 果的判断电路（图 2未示出）、 显示该检测结果的显示窗口 221、 设置在空腔 内壁上的与该第一锁紧元件相适配的第二锁紧元件、设置在外壳上的用于将固 定于该空腔内的该测试芯 210进行释放的释放元件 222等。
通过利用本发明所提供的基于试纸的检测装置，在检测过程中， 当淋到测 试芯的外壳上的液体沿着测试芯的外壳流动时，在密封圏的阻隔下， 液体将无 法通过检测仪本体的测试芯插入端口处的缝隙流入检测仪本体的内部，从而可 以有效避免检测过程中检测仪本体的内部受到液体污染的问题； 并且，通过保 护罩对检测仪本体的保护 ,可以避免将液体淋到测试芯中的试纸上时液体溅到 检测仪本体上。 可见， 通过利用本方案， 可以有效避免液体检测过程中对检测 仪本体的内部与外部的污染问题。 为了有效避免液体检测过程中对检测仪本体的内部与外部的污染问题，本 发明还提供一种基于试纸的检测装置。

其中，该第一位置为该测试芯 310被插入该检测仪本体 320后与该测试芯 插入端口相对的位置。
需要说明的是， 该密封圏 311可以被直接套进测试芯 310进而进行固定， 从而使得生产操作过程较为筒单；而由于现有技术中的测试芯的形状与检测仪 本体的形状相适配， 因此， 为了保证良好的密封性， 该密封圏 311的形状与该 测试芯 310的形状相适配，以使得该密封圏 311能够穿过该测试芯 310并固定 在第一位置处。
其中，由于该第一位置为该测试芯 310被插入该检测仪本体 320后与该测 试芯插入端口相对的位置， 因此， 设置于第一位置的密封圏 311可以密封该测 试芯 310被插入该检测仪本体 320后该测试芯插入端口处的缝隙。 同时， 需要 说明的是，在保证该保护罩 321能够容纳该检测仪本体 320至少一部分的前提 下， 该保护罩 321的形状并不局限于图 5所示的漏斗状， 还可以为桶状等。
需要说明的是， 在实际应用中， 该密封圏 311可以粘接在该测试芯 310的 外壳的第一位置处； 或者， 该测试芯 310的外壳的第一位置处设置有凹槽， 相 应的， 该密封圏 311被固定于该凹槽中当然， 该密封圏 311被固定在该凹槽中 后， 相对于该测试芯 310的外壳而言应该突出以保障能够密封缝隙。 同样的， 该保护罩 321的第一端可以粘接在该检测仪本体 320的测试芯插入端口处，且 该保护罩 321的第二端处于活动状态； 或者， 该保护罩 321的第一端以可拆卸 方式设置在该检测仪本体 320的测试芯插入端口处，且该保护罩 321的第二端 处于活动状态； 其中， 该保护罩 321的第二端处于活动状态具体指： 该保护罩 321的第二端未被固定在任何元件上。 本领域技术人员可以理解的是， 上述固 定方式仅仅作为示例， 并不应该构成对本发明方案的限定。
更进一步的， 当液体被淋到试纸上后，在将该基于试纸的检测装置放置到 实验桌等承载台上来等待检测结果时， 为了防止液体滴到承载台上， 该保护罩
321 的该第二端的横截面积可以大于该第一端的横截面积， 以使得该保护罩 321能够被翻转， 以容纳该测试芯 310。 例如： 图 5所示的保护罩 321为漏斗 状， 当该测试芯 310被插入到检测仪本体 320后， 该保护罩 321可以容纳该检 测仪本体 320的一部分，如图 6所示； 而在将该基于试纸的检测装置放置到实 验桌等承载台上来等待检测结果时，为了防止液体滴到承载台上，如图 7所示， 该保护罩 321可以被翻转以容纳该测试芯 310, 从而防止液体滴到承载台上。
