具体实施方式
下面结合具体实施例对本发明进行详细说明。以下实施例将有助于本领域的技术人员进一步理解本发明，但不以任何形式限制本发明。应当指出的是，对本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变化和改进。这些都属于本发明的保护范围。
实施例一
如图1和图2所示，根据本发明提供的一种采样检测装置，包括外筒1、内筒2以及筒盖3。外筒1能够容纳反应液，内筒2的外壁上具有多个试纸安装位4，检测试纸可以紧固安装在试纸安装位4上，且安装时保证检测试纸的层析部位于试纸安装位4靠近内筒2底部的一侧。进行多联检测时，可以将具有不同抗体的多个检测试纸分别安装到多个试纸安装位4，将采样拭子伸入外筒1内，利用外筒1内的反应液将采样拭子洗脱，然后将内筒2放入外筒1内，内筒2的底部结构将外筒1内液体的液位抬高，使外筒1内的液体能够浸没多个检测试纸的层析部，进而实现多联检测，且结构简单、操作方便。
具体地，外筒1可以是一体式结构，外筒1包括自下向上依次设置的反应液容纳腔11和主体容纳腔12，反应液容纳腔11和主体容纳腔12连通，主体容纳腔12远离反应液容纳腔11的一端敞开。且主体容纳腔12的侧壁包括透明结构，更为具体地，外筒1由透明材料制成。
内筒2可以是一体式结构，内筒2为中空结构，内筒2的上端敞开。在进行多联检测时，工作人员可以将洗脱后的采样拭子放入内筒2中，能够防止采样拭子污染环境。内筒2包括依次连接的挤压部21和试纸安装部23，试纸安装部23的周测设置有多个试纸安装位4。任一试纸安装位4均可以紧固安装一片检测试纸。试纸安装位4在试纸安装部23的外壁上呈凹陷设置，且试纸安装位4的开口边缘位置一体成型有限位挡边5。
本申请以试纸安装部23上具有八个试纸安装位4为例进行阐述：八个试纸安装位4在试纸安装部23的周侧呈等间隔设置，八个试纸安装位4的形状均为长条形，八个试纸安装位4的长度方向均与内筒2的长度方向平行，且行八个试纸安装位4的尺寸均相同。限位挡边5在任一试纸安装位4宽度两侧的开口边缘位置均一体成型有一个，任一限位挡边5的长度方向均与内筒2的长度方向平行，且任一限位挡边5均自试纸安装位4的开口边缘位置向该试纸安装位4的上方延伸，从而使检测试纸能够紧固安装在试纸安装位4上，减少检测试纸意外脱落的情况发生。且八个试纸安装位4上的检测试纸在安装时，可以保证八个检测试纸位于同一高度。
如图1和图2所示，外筒1能够容置内筒2，试纸安装部23位于主体容纳腔12内，挤压部21探入反应液容纳腔11内，且挤压部21与反应液容纳腔11的内壁配合形成有允许反应液通过的间隙。挤压部21的形状和反应液容纳腔11的形状相匹配，使挤压部21能够尽可能的将反应液容纳腔11内的液体全部排出。例如，可以将挤压部21和反应液容纳腔11二者均设置为圆柱形，挤压部21的尺寸略小于反应液容纳腔11的尺寸，从而使挤压部21能够探入反应液容纳腔11内并将其中的液体排出。需要明确的是，挤压部21和反应液容纳腔11二者的形状可以是规则形状、也可以是不规则形状，只需要满足挤压部21能够探入反应液容纳腔11内即可。
进一步地，挤压部21的外壁上可以开设有导流槽22，导流槽22自挤压部21远离试纸安装部23的一端向靠近试纸安装部23的方向延伸。借助导流槽22能够使反应液容纳腔11内的液体更容易排出。
更为具体地，筒盖3与外筒1可拆卸式连接，且筒盖3封闭或打开主体容纳腔12的敞开侧。可拆卸连接的方式可以是螺纹连接、插接等现有技术中常用的连接方式。筒盖3内部嵌设安装有压片6，当筒盖3在外筒1上安装到位后，压片6与内筒2抵接，压片6可以采用橡胶材质。一方面可以防止外筒1内的液体，自外筒1与筒盖3的连接处流出；另一方面利用压片6对内筒2的轴向进行限位，减少内筒2的运动自由度，便 于工作人员观检测结果。
本申请的多联检装置尤其是适用于如下场景：
1、呼吸道拭子类：采样完成后将采样拭子在外管底端的反应液容纳腔11内洗脱后，将采样拭子弃置于内筒2，并将内筒2放入外筒1，完成层析，可完成常见的FLUA/FLUB/RSV/ADV/RV/HPIVs/MP/ncov-19等呼吸道病原体组合。
2、粪便样本类型：采样勺采集粪便样本后置于外管底部的反应液容纳腔11内，充分混匀后，将内管插入外筒1，完成层析，可完成常见的HRV/ADV/Norovirus/HP/钙卫/隐血等多指标组合。
3、血液、尿液样本类：可将液体采集后直接滴加到外筒1底部的反应液容纳腔11内，充分混匀后，将内筒2插入外筒1内，完成层析，可用于常见的血源类指标检测。
本装置可应用于多检测场景，实现一次采样多靶标快速检测，简单快速，15min结果判读，可实现样本进，结果出。并且采样废弃物均密封在检测装置中，不对环境造成污染。
实施例二
基于实施例一，根据本发明提供的一种采样检测装置，内筒2可以是分体式结构。
如图3和图4所示，试纸安装部23包括安装主体71和连接座72，安装主体71和连接座72二者插接连接，连接座72远离安装主体71的一端与挤压部21紧固连接。具体地，连接座72靠近安装主体71的一端一体成型有插接轴，安装主体71靠近连接座72的一端开设有插接口，插接口在任一两个相邻的试纸安装位4之间均开设有一个，插接轴与插接口一一对应且插接配合，从而实现了试纸安装部23的分体式连接，进而提高了检测试纸在试纸安装位4上安装的便捷性，且结构简单，便于制造。
再进一步地，插接轴包括定位段和固定段，定位段与插接口配合实现连接座72与安装主体71之间的定位，固定段与插接口配合实现连接座72和安装主体71之间的紧固连接。
挤压部21的外壁上开设有导流槽22，连接座72靠近挤压部21的一端开设有溢流口75，溢流口75连通导流槽22和内筒2的内部空间。外筒1内的液体能够沿着导流槽22和溢流口75流入内筒2的内部空间内。试纸安装位4位于连接座72的一侧开设有第一导通孔76，第一导通孔76连通试纸安装位4和内筒2的内部空间，使液体能够从检测试纸的两侧浸没检测试纸的层析部，从而保证层析效果和层析速率。
特别地，当本实施方案用于呼吸道拭子类采用检测时，采样拭子在反应液容纳腔11内洗脱后，工作人员将采样拭子的采样端向下放置在内筒2中，之后再将内筒2放入外筒1中，挤压部21将反应液容纳腔11内的液体挤出，液体沿着导流槽22和溢流口75进入内筒2、内筒2和外筒1的间隙中。进入内筒2的液体浸没采样拭子的采样端，能够防止对采样拭子洗脱不完全导致的检测误差，提高了检测的准确性。
实施例三
基于实施例一，根据本发明提供的一种采样检测装置，内筒2可以是分体式结构。
如图5、图6以及图7所示，试纸安装部23包括多个安装侧板81，任意相邻的两个安装侧板81均卡接连接。试纸安装部23的形状可以是矩形、圆柱形等规则形状，也可以是不规则形状。其中，一种可行的实施方式为试纸安装部23的形状呈矩形，试纸安装部23包括四块安装侧板81，任一块安装侧板81的外侧壁上均设置有两个试纸安装位4，且任一安装侧板81的一侧均具有卡接块82、另一侧均具有卡接槽83，任一安装侧板81上的卡接块82均与其相邻的安装侧板81上的卡接槽83卡接连接，从而实现试纸安装部23整体的组装。
进一步地，任一安装侧板81的底部均一体成型有夹持块84，试纸安装部23底部的四个夹持块84配合夹持挤压部21。例如，挤压部21呈圆柱形，夹持块84与挤压部21接触部分的形状为与挤压部21弧度相同的四分之一圆弧，从而使四个夹持块84配合能够稳定夹持挤压部21，实现内筒2的组装。试纸安装位4靠近挤压部21的一侧开设有第二导通孔85，第二导通孔85连通试纸安装位4和内筒2的内部空间。
在本申请的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
与现有技术相比，本发明具有如下的有益效果：
1、本发明通过将多个检测试纸分别安装在内筒外壁上的多个检测试纸安装位上，将反应液放置在外筒内，采样后，将样本加入反应液容纳腔，在反应液容纳腔内充分混匀，然后将内筒放入外筒中，内筒的挤压部将反应液容纳腔内的液体挤入 主体容纳腔内，且液体将多个检测试纸的层析部浸没，等待一定时间再进行结果判断，完成多联检测，且结构简单，操作方便，批量检测效率高。
2、本发明通过在挤压部设置导流槽，便于挤压部伸入反应液容纳腔时，液体自反应液容纳腔流入主体容纳腔内，通过挤压部与反应液容纳腔相互配合，高效的利用反应液，减少无效液体，提高样本利用率。
3、本发明通过将内筒设置位为中空结构，并使内筒的上端敞开，在进行多联检测时，工作人员可以将采样器具(如采样拭子等)放入内筒中，整个检测过程在密闭环境内完成，能够有效防止反应液容纳腔内样本及采样器具残留样本造成污染环境，增强环境安全，降低操作人员感染风险，且进入内筒的液体浸没采样器具的采样端，能够防止对采样器具洗脱不完全导致的检测误差，有助于提高检测的准确性。
以上对本发明的具体实施例进行了描述。需要理解的是，本发明并不局限于上述特定实施方式，本领域技术人员可以在权利要求的范围内做出各种变化或修改，这并不影响本发明的实质内容。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
