实施例一
如图1-图8所示，本发明提供一种样本采集检测卡，包括盒体和采样棒10，盒体包括上盖20和下盖30，所述上盖20与所述下盖30之间设置有试纸条40，上盖20上设有观察窗21和进样口22，采样棒10的一端为采样端11，另一端为手柄端12；
所述下盖30上设置有加样腔31，所述加样腔31可容纳所述采样端11的采样部111，所述加样腔31底部设置有出口311，所述试纸条40的加样区41位于所述出口311处；
所述盒体与所述采样棒10之间还设置有将所述采样棒10固定在所述盒体上的固定结构，所述采样棒10固定在所述盒体上时，所述采样部111可变形。
其中，采样端11的采样部111设置在采样端11的底部，或者，采样端11可全部为采样部111。进样口22位于加样腔31的上方，采样端11的采样部111可经过进样口22进入加样腔31，或加样腔31延伸至进样口22内，采样端11的采样部111可直接进入加样腔31。下盖30上设置放置试纸条40的试纸槽32。
加样腔31底部的出口311，可设置在加样腔31底部任一位置，可选的，出口311可设置在加样腔31底部中央。
在本发明的另一个可选实施例中，所述加样腔31底部的周缘高于所述出口311处。具体地，加样腔31的底面可设置成弧面形，弧形底在出口311处，或加样腔31的底面可设置成斜平面，斜平面的最底部在出口311处。当采样部111变形，使样本挤出后，样本向低处流，流向设置在加样腔31底部的出口311，使样本流到加样区41。
试纸条40的加样区41位于出口311处，即试纸条40的加样区41可位于出口311内、出口311底部、或经过出口311进入到加样腔31内。试纸条40的加样区41位于出口311内，可使试纸条40更接近采样端11底部的采样部111。更进一步地，试纸条40的加样区41顶面与加样腔31的底面平齐，或加样区41经过出口311进入到加样腔31内时，采样部111可直接与试纸条40的加样区41挤压，使样本直接进入加样区41，使采样部111需要吸收的样本量更少。
采样部111包括设置在所述采样端11底部的吸水物，采集样本时吸水物用于吸收液体类的样本，吸水物由软体材料制成，如海棉、纱布等，设置在采样端11底部，在外力作用下可变形。采样部111可全部由吸水物构成，采样部111还可由安装在采样端11底部的支架及安装在支架上的吸水物构成。
采样棒10固定在盒体上时，采样部111可变形。具体地，采样棒10固定在盒体上时，只需要使采样部111与加样腔31的侧壁和/或底壁干涉，采样部111与加样腔31的侧壁和/或底壁挤压，使采样部111变形。而使采样部111与加样腔31的侧壁和/或底壁干涉，只需要通过设计采样部111和加样腔31的尺寸或设计固定结构的位置尺寸即可。
本发明中，采样棒10的采样部111吸收样本后，将采样棒10固定在盒体上，使采样部111与加样腔31的侧壁和/或底壁挤压进而使采样部111变形，将采样部111吸收的样本逐渐挤压进加样腔31，由于试纸条40的加样区41设置在加样腔31底部的出口311处，加样腔31与试纸条40的加样区41更接近，样本直接进入加样区41，可使加样腔31内的样本全部流到加样区41，而无需预留多余的样本，采样部111需要吸收的样本量也少，因此，可以减小采样部111体积，进而使采样棒10的采样端11整体体积变小。
本发明实施例通过将加样腔31设置在下盖30上，并将试纸条40的加样区41设置在加样腔31的出口311处，使加样腔31与试纸条40的加样区41直接接触，样本与加样区41直接接触，可以使样本的需求量减小，从而使采样棒10的采样部111体积可以减小，进而使采样棒10的采样端11整体体积变小，用户采样时间显著减少，使用时感觉更舒服，提高了用户体验感。
实施例二
如图8所示，在本发明的一个可选实施例中，所述采样棒10的采样端11设置有显示部114，所述采样部111设置在所述显示部114下侧。显示部114用于显示采样部111是否采集了足够的样本，当采样部111采集了足够的样本时，显示部会发出提示指令，例如颜色变化、发出声音或发光等。
具体地，所述显示部包括指示试剂，所述指示试剂遇水后颜色可发生变化。所述指示试剂包含但不限于无水硫酸铜、变色硅胶、变色色素（如柠檬黄），遇水后颜色可发生变化。指示试剂可直接安装在采样棒10内，显示部还可以包括试剂盒，指示试剂放置在试剂盒内，试剂盒安装在采样棒10内。
实施例三
如图5-图7所示，在本发明的一个可选实施例中，所述固定结构包括：
分别设置在所述加样腔31的相对两侧壁上的插孔312和第一弹性倒扣313；
设置在所述采样端11的相对两侧壁的可插入所述插孔312的第一限位插块112和与所述第一弹性倒扣313勾扣配合的限位卡扣113。
本发明实施例中，插孔312可以是加样腔31侧壁上的通孔或盲孔，第一限位插块112可以是采样端11的侧壁上的凸出块，第一限位插块112的外形尺寸略小于插孔312，使第一限位插块112可以插入插孔312内，由插孔312的顶壁限制第一限位插块112的位置。第一弹性倒扣313和限位卡扣113的位置还可以互换，是本发明的等同方案，也是本发明保护的范围。将采样棒10固定在盒体上时，先将第一限位插块112插入插孔312内，再使限位卡扣113放置在加样腔31的侧壁上方，最后用力压采样棒10的手柄端12，使第一弹性倒扣313弹性变形，限位卡扣113卡入第一弹性倒扣313内勾扣配合，从而使采样棒10固定在盒体上。
在本发明的另一个可选实施例中，试纸槽32贯穿加样腔31侧壁，试纸条40可直接从加样腔31上方放入到试纸槽32，方便试纸条40的安装。
实施例四
在本发明的一个可选实施例中，所述固定结构包括：
设置在所述采样端11的相对两侧壁的可插入所述上盖20内侧的第二限位插块和与所述上盖20内侧勾扣配合的第二弹性倒扣。
本实施例中，上盖20内侧起到了实施例三中插孔312和限位卡扣113的作用，上盖20内侧可限制第二限位插块的位置及与第二弹性倒扣勾扣配合。具体使用方式与实施例三相同，在此不做赘述。
实施例五
如图4所示，在本发明的一个可选实施例中，所述加样腔31的顶部平齐所述上盖20顶面或低于所述上盖20顶面。
本实施例中，加样腔31的顶部平齐上盖20顶面或低于上盖20顶面，则加样腔31的顶部未凸出上盖20顶面，上盖20顶面是平整的。上盖20与下盖30的安装，最简单的方式就是通过勾扣配合，将卡钩挤压变形后扣入卡扣内。本发明中，上盖20顶面是平整的，可以使用滚筒碾压的方式，将上盖20与下盖30压合，将卡钩挤压变形后扣入卡扣内勾扣配合，可使用自动化生产设备进行滚筒碾压，无需人工压合，可提高生产效率，节约人工成本。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
