Description

一种盖子及样本收集检测装置 技术领域
本实用新型涉及一种盖子，特别是用于盖合和密封样本收集检测装置的盖子，以及与之配套的样本收集检测装置。
背景技术
下面的背景技术用于帮助读者理解本实用新型，而不能被认为是现有技术。
利用免疫结合反应原理来检测样本中是否存在被分析物质的这一技术被广泛用在各个领域。可以用它来检测各种生物样本(唾液，血液，尿液，血清，汗液等等)的被分析物质来监测疾病和人类的健康状况(早孕，肿瘤，传染病，毒品等等)。这种检测技术的根本原理是建立在免疫分子之间具有特异结合的性能，例如抗体与抗原，半抗原/抗体，生物素与抗生物素等等。
在医疗诊断领域，利用检测装置或者检测杯未收集检测液体样本，并判断液体样本中是否含有被分析物，是一种比较普遍的方法。这样的检测装置或者检测杯一般要求样本被收集在样本容器内，相关技术人员括入一检测试剂条并使试剂条的一部分浸没在样本中，若干时间后取出试剂条并读取检测结果。更有改进的方式，在样本收集容器上加上封闭盖体后进行操作。目前，己存在有许多密闭装置，如美国专利US 4976923，US 5429804，和US6726879所揭示的装置。这些装置是将检测试纸条固定在检测装置的盖子上。使用时，将容器翻转或者倾斜使样品浸润检测试剂条进行检测。
2003年2月6日公开的美国专利申请US2003/0027359A1揭示了一种检测尿杯。该检测尿杯在盖子盖到杯子的开口后仍需用推杆推动柱式活塞运动而使流体样本从杯子腔体流出并湿润检测元件。中国专利申请200510113911.5公开了一种用于液体样本的检测装置，该装置中，检测试剂条位于杯盖上，杯盖和杯体之间有一条管子，通过将液体样本压入管子使液体进入杯盖进行检测。
通常，在这类检测装置中，大部分的盖子均采取旋合的方式来盖合或密封检测装置的杯口，在使用中需要操作者双手配合才能打开或盖合盖子与检 测杯，非常不方便；并且，在旋合的方式中，因需要盖子与检测杯相互转动,会因操作者用力过大时，使液体在检测杯中被晃动导致溅出来，从而污染操作者。此外，在将这类装置中，将样本从收集腔内如何到检测腔，转移多少样本量都是会影响检测元件检测的准确性。
实用新型内容
本实用新型针对上述的问题，提供了一种新的盖子。该盖子可以扣压在样本收集检测装置的收集腔上来密封并盖合收集腔。具体来说，本实用新型中提供的一种盖子，该盖子用于盖合并密封样本收集检测装置，其中，所述盖子包括盖体，密封部件和固定部件；所述密封部件和固定部件均位于盖体上。密封部件用于密封需要被盖合的收集腔，而固定部件则用于将密封部件固定在盖子上。
一些优选的实施方式中，所述盖体的中部包括向下的凸起；所述密封部件和固定部件环绕于盖子凸起侧壁边缘。
另一些优选的实施方式中，所述凸起为阶梯式凸起；所述密封部件位于第一阶梯上；所述固定部件位于第二阶梯及密封部件上。
具体来说，位于盖体上的凸起由凸起的底部开始呈阶梯式减小，这样，方便在凸起上安放密封部件和固定部件。具体来说，凸起包括第一阶梯和第二阶梯，第一阶梯接近凸起的底部，其横截面尺寸大于第二阶梯，密封部件环绕在凸起的第一阶梯处；并且，密封部件的厚度与第一阶梯的阶梯高度相同，这样，当固定部件环绕于第二阶梯处时，固定部件的底部一部分位于第二阶梯上，其余部分则位于密封部件上。
一些优选的实施方式中，所述盖体的凸起与盖体的外侧壁形成环形的凹槽；所述环形凹槽用于容纳收集装置腔体的腔口侧壁。
一些优选的实施方式中，所述密封部件包括具有弹性的环形密封圈；所述密封圈外侧壁上包括2个对称的环状凸起。
密封圈的2个环状凸起用于与样本收集检测装置的收集腔的内侧壁接触并密封内侧壁。这2个环状凸起对称的位于密封圈侧壁的两个外侧边，更为具体的，在密封圈上设计两个环状凸起，使其中间形成一个环形凹陷，在环 状凸起与侧壁形成密封过程中，会形成一定的挤压力，导致环形凸起因具有弹性而向中间的凹陷部分稍稍变形，这样，能够使环形凸起与收集腔的内侧壁形成更好的密封效果。
一些优选的实施方式中，所述固定部件包括环形的卡环；所述卡环的一端固定卡合在凸起的顶端。
具体来说，卡环的作用主要是用于将密封部件固定在凸起上，因此，卡环自身必须固定在凸起上。一个具体的实施例中，卡环的横截面结构为
Figure PCTCN2016083234-appb-000001
在卡环的上部一端
Figure PCTCN2016083234-appb-000002
用于连接密封圈及第二阶梯，中部
Figure PCTCN2016083234-appb-000003
垂直端用于贴合并固定在盖体凸起上，下部的一端
Figure PCTCN2016083234-appb-000004
用于卡合在盖体凸起的顶部。更为具体的，在凸起顶部还包括第三阶梯，该第三阶梯的横截面为斜角形结构；而卡环的中部与下部连接处具有同样角度的转角，这样，卡环的这一转角与第三阶梯紧密结合，从而被固定在一起。这样，卡环与凸起固定连接，同时将密封圈限定在凸起的第一阶梯区域，使其固定在盖体凸起上。
本实用新型还提供一种样本收集检测装置，包括样本收集腔，与收集腔液体相连通的检测腔，其中，所述样本收集装置还包括盖子，所述盖子包括盖体，密封部件和固定部件；所述盖体上包括阶梯式凸起，所述密封部件与固定部件环绕固定在凸起的阶梯上。
一些优选的实施方式中，所述盖子上还包括与样本收集装置转动连接的转轴，样本收集检测装置的收集腔的腔口上包括容纳转轴的空腔。转轴在空腔中可以自由的转动，从而带动盖子在收集腔的上方进行转动，方便盖子的开合。
一些优选的实施方式中，所述盖子上还包括可活动的卡扣，所述收集腔的腔口外侧与卡扣对应处具有凸片。在盖子下压盖合密封到收集腔的腔口处后，卡扣与凸片配合，将盖子固定到收集腔上。
收集检测装置的盖子扣压在收集检测装置的腔口上，开合方式为使盖体的一侧(盖体与收集检测装置的连接处)为支撑点，上下开合即可。因此，使用方式上可以通过单手操作，并且，也可以保持检测装置的收集腔部分不动，使位于其内的液体不会晃动或溅出。在满足盖子密封收集检测装置的基础上，操作方便及安全。
一些优选的实施方式中，所述样本收集检测装置还包括：
位于收集腔底部并与收集腔相通的定量塞装配孔；

一些优选的实施方式中，还包括套设在所述定量塞的外部的密封套，所述密封套至少具有一个与所述定量槽的开口端重合的开口。
一些优选的实施方式中，密封套沿其圆周方向及轴向设有若干个硅胶密封圈。
一些优选的实施方式中，还包括所述钥匙孔配合的钥匙；盖子的顶部设有收容所述钥匙的存放槽。
本实用新型中，通过将收集腔与定量塞装配孔相遇，并将定量塞装配孔和检测腔相遇，在定量塞装配孔内括设有定量塞，定量塞上设有定量槽。通过钥匙可以旋转运量塞，从而可将由第一腔内的液体样本流入运量槽，并通过旋转将该定量槽内的液体样本送入检测腔内，液体样本流经设在检测腔体内部的检测元件后被吸收，这样就在检测元件上显现出检测结果。由于在定量塞上加工出定量槽，从而使得每次取的液体样本的体积相同，提高了检测结果的准确度，而且取液体样本的定量塞由直线推动改为旋转运动，其防漏效果更好。
有益效果
本实用新型的盖子盖合收集腔时上下压合并密封收集腔，使样本收集检测装置达到更好的密封效果，同时，使该装置的开合操作更方便及更安全。并且，该样本收集检测装置可以定量运送样本至检测腔，以保证检测腔内的检测元件检测准确，同时旋转推动定量塞以及增加密封套可以有效防止样本收集检测装置漏液。

具体实施方式
下面对本实用新型涉及的结构或这些所使用的技术术语做进一步的说明。在下面的详细描述中，图例附带的参考文字是这里的一个部分，它以举例说明本实用新型可能实行的特定具体方案的方式来说明。我们并不排除本实用新型还可以实行其它的具体方案和在不违背本实用新型的使用范围的情况下改变本实用新型的结构。
如图1所示，本实用新型的盖子100,主要包括三个部分：盖体110，密封部件120和固定部件130.其中，盖子100的主体为盖体110，该盖体110用于盖合样本收集检测装置800的收集腔200的开口230，以闭合收集腔200；而密封部件120则用于与收集腔的开口230形成密封，以防止收集腔200内的液体泄漏 出来；固定部件130主要用于将密封部件120固定在盖体110上，使密封部件120在密封的过程中，即使受到一定的压力，也不会在盖体110上移动。
具体来说，在盖体110上，包含有一个凸起111，该凸起111位于盖体110的中部，更为具体的，该凸起111为中空的凸起，也就是说凸起111相对应与盖体的另一面为凹陷，如图1，图2和图3所示，其中，密封部件120和固定部件130均环绕于凸起111的外侧壁并被固定在凸起111上。该凸起111为圆筒形凸起，更为优选的，凸起111的直径并不一直相同，成阶梯式减小。更为具体的，如图3和6所示，该凸起111形成第一阶梯112，第二阶梯113，以及第三阶梯114；第一阶梯112、第二阶梯113的直径递减。并且，第一阶梯112位于凸起111的底部，而第二阶梯113位于凸起111的中部。第三阶梯114为横截面为斜面的阶梯，其位于凸起111的顶端。这些阶梯的设计是为了更好的将密封部件和固定部件固定在盖体的凸起上，从而在盖体密封收集检测装置的过程中，不会发生位置的移动而导致密封不严实的情况。具体来说，密封部件环绕在第一阶梯与第二阶梯之间的凸起侧壁上，其底部位于第一阶梯上，密封部件的顶端与第二阶梯齐平，一起形成一个平面用于放置固定部件。
一些具体的实施例中，密封部件为具有一定弹性的密封圈120，该密封圈120可以使用硅胶或橡胶以及弹性较大的塑料材质。如图1和图6所示，该密封圈120为圆环形结构，具有一定的厚度，以保证密封的效果，通常厚度在0.5-1cm之间。优选的，在密封圈120的侧壁上还具有环形的凸起121，该环形凸起121为2个，分别对称的位于密封圈120的两个外侧边。相对应的，在环形凸起121的中间形成一个凹陷122。密封圈120上设计凸起121和凹陷122能够使密封圈120在密封的过程中具有一定的缓冲，能够有变形的空间，从而填充密封圈120与收集腔200侧壁之间的空隙，更好的与收集腔200的侧壁接触及密封。
一些实施例中，固定部件130为一定形状的卡环130，该卡环130为圆环形结构，其横截面呈

如图1所示，在卡环的上端131

的圆环面位于密封圈120及第二阶梯113平面上，卡合住密封圈120；中部

垂直端132用于贴合并固定在第二阶梯113与第三阶梯114之间的凸起111侧壁上， 下部的一端133
Figure PCTCN2016083234-appb-000008
卡合在盖体凸起111的顶部，如图6剖面图所示。其中，卡环130的中部和下部连接的转折处具有坡面，用于与第三阶梯114的坡面相配合固定。卡环130通过与第二阶梯113及第三阶梯114的卡合，固定在凸起111上，因此，位于卡环130和第一阶梯112之间的密封圈120也被固定在凸起111上，从而被固定在盖体110上。
如图3和图6所示，盖体110的凸起111与盖体110的外侧壁形成环形的凹槽115；环形凹槽115用于容纳收集装置腔体的腔口230侧壁。此外，在盖体上凸起对应的凹陷内处还具有另一存放槽117，该存放槽117中可以放置钥匙500，如图7所示。
另一方面，本实用新型还提供一种样本收集检测装置，具体来说，该样本收集检测装置800包括样本收集腔200，与收集腔液体相连通的检测腔300，以及本实用新型提供的新的盖子100。其中，盖子100与收集腔200连为一体，具体的，盖子100上包括与样本收集装置转动连接的转轴118，样本收集检测装置的收集腔200的腔口230上包括容纳转轴的空腔210。转轴118被安置在空腔210内，使盖子100与收集腔200连接在一起，转轴118在空腔210中可以自由的转动，从而带动盖子199在收集腔200的上方进行转动，方便盖子100的开合。
一些优选的实施方式中，所述盖子100上还包括可活动的卡扣116，所述收集腔的腔口230外侧与卡扣116对应处具有凸片220。在盖子100下压盖合密封到收集腔的腔口230处后，卡扣116与凸片220配合，将盖子100固定到收集腔200上。盖子上卡扣116位于转轴118的对立面，方便盖子100与收集腔200之间的盖合。
如图4所示，在样本收集检测装置800上，还包括位于收集腔底部240与收集腔连通的定量塞装配孔400，该装配孔400还同时与检测腔相连通，具体如图4和图6所示，在检测腔的下腔310具有与装配孔连通的通道311，以及收集腔与装配孔的通道201，因此，装配孔使检测腔300与收集腔200相连通。
样本收集检测装置800还包括一个定量塞600，如图4和图5所示，该定量塞可转动的插设在量塞装配孔400内，所述定量塞600上设有定量槽6 10，且其一端设有钥匙孔620，钥匙500与所述钥匙孔620配合，通过将该钥匙500括入所述钥匙孔620内，可转动定量塞600。通过转动定量塞600，将其上的定量槽610的开口端分别与通道201和通道311处对应连通，从而将收集腔200内的一定量的液体先转移到定量槽中，再从定量槽610中转移至检测腔内，从而被位于检测腔上腔320内的检测元件700所吸收并进行检测，实现本样本收集检测装置800的功能。
由于在定量塞600上加工出定量槽610，从而使得每次取的液体样本的体积相同，提高了检测结果的准确度，而且取液体样本的定量塞600由直线推动改为旋转运动，其防漏效果更好。
为了进一步优化上述技术方案，如图5所示，本实用新型还可包括套设在所述定量塞600外部的密封套900，该密封套的邵氏硬度为20-60A，该密封套900至少具有一个与所述定量槽610的开口端重合的开口。即将该密封套900套设在定量塞600上后，定量塞600的定量槽610同样可与外界相通，不会遮挡定量槽610的开口端。通过在定量塞600上套设密封套900，使得由密封套900和定量塞600组成的定量塞组合与定量塞装配孔400的配合面更加密封，进一步提高了防漏效果。优选的，密封套900沿其圆周方向及轴向设有若干个硅胶密封圈910密封。密封套900为二次注塑件，如TPE(Thermo plastic Elastomer，热塑性弹性体)二次注塑件，TPE二次注塑，一般是指先注塑硬质塑料，再通过注塑工艺在硬质塑料材质表面包覆一层比较薄的TPE、TPR(Thermo plastic Rubber，热塑性橡胶)、TPV(Thermo plastic Vulcanizate，热塑性硫化橡胶)、TPEE(热塑性聚醋弹性体)、TPO(聚烯炬热塑性弹性体)或硅胶类材料等。以增加制品的舒适的触感，止滑性能及缓冲击性能。
