Description

液体采集装置 技术领域
本发明涉及医学检验和毒品检测领域，特别涉及一种液体采集装置。
背景技术
在医学检验和毒品检测领域，待分析液体样品如尿液、唾液等的采集是检测过程的一个环节。常用的一种采集液体的方法是将一个液体吸收体放置于被采集者的液体采集部位，经过一定时间后取出液体吸收体，然后在特定的装置中将液体挤出或洗脱用于后续测试。为便于操作，如图1所示，一般会用粘结剂将液体吸收体2固定在一个手柄1上。用这种装置采集液体样品的时候，通常难以判断吸收体是否已经吸收了足够的液体，即使规定一定的采集时间，因为个体之间的差异，在规定时间内采集到的液体量也有很大差别。比如在唾液采样过程中，由于不同个体的唾液分泌差别较大，在相同的时间内吸收体能吸收到的唾液量差别比较大。因此在液体样品采集过程中能够指示吸收体中液体含量的液体采集装置具有很好的实用意义。目前常用的方法是在采集装置的某个部位加入染料，样品采集过程中染料随液体的渗透而移动，从而判断吸收体中的液体含量。这种方法通常给使用者一些不安全的隐患，比如在采集唾液的过程中，如图2所示，如果使用者压迫-放松吸收体数次后，指示部件3中的染料会反渗到吸收体并进入使用者口腔。另外加入的染料也可能干扰样品中目标成份的检测。
此外，现有的唾液采集装置结构较为复杂，生产成本、使用成本高，如现有技术中的一种唾液采集装置，属于唾液采集技术领域。本实用新型包括上盖、下盖和棉签棒；所述棉签棒的一端设有凸台，凸台上设有棉签头；所述上盖和下盖之间装有试纸条；所述上盖上设有读取试纸条结果的窗口，所述上盖的一端设有容纳棉签头的安放槽；所述安放槽的内壁设有与棉签棒凸台相匹配的卡环；所述安放槽底部设有液流孔，所述试纸条的一端设在液流孔的下端；所述上盖和下盖上设有匹配的插针、插环，上盖和下盖之间通过插针、插环连接；所述上盖、下盖上设有加强筋、固定筋和支撑筋。该种唾液采集装置结构复杂，操作不便。

具体实施方式
下面结合附图对本发明的优选实施例进行详细介绍，然而，本发明可以用许多不同的形式来实施，并且不局限于此处描述的实施例，提供这些实施例是为了详尽地且完全地公开本发明，并且向所属技术领域的技术人员充分传达本发明的范围。对于表示在附图中的示例性实施方式中的术语并不是对本发明的限定。在附图中，相同的单元/元件使用相同的附图标记。
除非另有说明，此处使用的术语包括科技术语对所属技术领域的技术人员具有通常的理解含义。另外，可以理解的是，以通常使用的词典限定的术语，应当被理解为与其相关领域的语境具有一致的含义，而不应该被理解为理想化的或过于正式的意义。
需说明的是，在本发明中，附图1中的上、下、左、右即视为本说明书中所述的液体 采集装置的上、下、左、右。
如图3至图12所示，本发明提供一种液体采集装置，包括手柄1、与手柄1固定连接的吸收体2和装配在手柄1和/或吸收体2上的指示部件3，其中，指示部件3包括纤维体31和指示芯体32，指示芯体32的外周表面上设置标识部，纤维体31全部或部分包覆指示芯体32的标识部，纤维体31与吸收体2连通，当吸收体2将采集的液体传递给纤维体31时，纤维体31的透明度随着吸收的液体量的增加而提高。
纤维体31在液体采集前，透明度低或处于不透明的状态，指示芯体32的标识部被遮蔽，透过纤维体31无法观察到指示芯体32的标识部，当吸收体2采集到液体后，由于吸收体2与纤维体31连通，吸收体2吸收到的液体可以传递给纤维体31，纤维体31的透明度随着吸收的液体量的增加而提高，当纤维体31被液体完全浸润时，纤维体31几乎处于透明的状态，透过浸润的纤维体31，可以清楚观察到的指示芯体32的外周表面上设置的标识部。
<吸收体>
吸收体2用于吸收液体样本，完成后将液体样本挤出，进行后续化验分析，在本发明中，吸收体的材料优选为多孔材料，如海绵或粘接纤维等，材料密度优选为0.04-0.12g/cm 3，既具有一定的弹性，又方便挤压。
<纤维体>
纤维体31由皮芯结构的双组份长丝或短纤粘结制成。双组份纤维的皮层为聚乙烯、聚丙烯或聚烯烃中的至少一种。
双组份纤维中的芯层可以为聚乙烯、聚丙烯、聚酯、尼龙等。当双组分纤维为长丝时，纤维体31具有较快的液体传导速度，有利于缩短显色时间。当双组分纤维为短纤时，由于短纤在纤维体31中随机堆叠，在相同厚度的情况下，纤维体31能够更好地遮蔽指示芯体32的标识部，从而提高纤维体31浸润前后标识部清晰度变化的对比度。为使纤维体31适合于体外诊断装置的应用，通常设置纤维体31的孔隙率为65-95％。
为增加纤维体31吸取和传导液体的能力，可以用表面活性剂如曲拉通-100、吐温-20等对纤维体31进行处理，以增加纤维体31的亲水性。
<指示芯体>
指示芯体32可以是导液材料，也可以是不导液材料。指示芯体32为导液材料时可以由长丝或短纤制成，但优选长丝。由于长丝在指示芯体32中总体上呈平行状态并与液体传导方向一致，长丝制成的指示芯体32传导液体速度快，有利于缩短显色时间。
指示芯体32为导液材料时由皮芯结构的双组份纤维粘结制成，如聚乙烯/聚丙烯纤维，聚乙烯/聚酯纤维，共聚酯/聚酯纤维，尼龙/聚酯纤维等。
指示芯体32的标识部可以是指示芯体32外周表面上形成的颜色、图案或者文字。指示芯体32可以用有色的纤维粘结制成或者将无色的纤维粘结后进行着色,从而在指示芯体32的外周面上形成呈现颜色的标识部。着色剂应着色牢固不被液体溶解、并且不干扰检测装置对待分析物的检测，优选颜料。也可以选用对指示芯体32着色力强且不干扰检测的染料。指示芯体32的颜色可以为宝蓝色、绿色、玫红色、粉红色、橙红色等较为亮丽的颜色。亮丽的颜色形成标识部有助于提高在纤维体31浸润时标识部清晰度变化的对比度。不同的颜色选用可以根据使用者的喜好而定。
指示芯体32的外周表面也可以设置图案或者文字来作为标识部。或者指示芯体32的外周表面上由颜色、图案或者文字的组合来形成标识部。
<指示部件>
指示部件3包括纤维体31和指示芯体32，纤维体31全部或部分包覆指示芯体32的标识部。也就是说，纤维体31可以仅包覆部分的标识部，也可以包覆全部的标识部。同样的，指示芯体32可以被纤维体31部分包覆，也可以整体被指示芯体32包覆。
指示部件3可以装配在手柄1上，也可以装配在吸收体2上，或者同时装配在手柄1和吸收体2上。指示部件3的安装位置可以根据实际需要选择，只要能保证在包覆的纤维体31变透明的情况下，所需要观测的标识部处于肉眼可见范围内，且纤维体31与吸收体2相连通。指示部件3的纤维体31和指示芯体32也可以同时与吸收体2相连通。当指示部件的指示芯体32用长丝制成，并且纤维体31由短纤制成时，指示部件3整体上既具有快速的液体传导速度，同时在液体采集过程中也有显著的标识部清晰度变化。
<挡板>
当吸收体2的直径大于手柄1的直径时，可以在手柄1靠近吸收体2的端部设置有挡 板12。挡板12可以与手柄1一体成型，也可以分体成型后，将挡板12和手柄1固定装配在一起。
如此设计，可以方便采集人员的操作，在利用挡板12挤压吸收体2时，将更彻底地使吸收体2内吸收的液体挤出。
根据本发明的液体采集装置，当吸收体2采集到足够量的液体时，吸收体2将采集的液体传递给纤维体31，纤维体31的透明度随着吸收的液体量的增加而提高。当使用者可以透过纤维体31观察到指示芯体32外周表面的标识部时，则可以判断液体采集装置已经采集到足够量的待检测液体。
根据本发明的液体采集装置，设计独特、结构简单，使用简洁方便，具有很高的实用价值和经济价值。

本实施例中，手柄1靠近吸收体2的部分设有沿手柄1轴向方向延伸的内腔11,指示部件3插入内腔11中，内腔11与指示部件3对应的周壁由透明材料制成，指示部件3的纤维体31与吸收体2连通。
如图3所示，手柄1靠近吸收体2的部分设置内腔11，内腔11部位的手柄1材料为透明材料，指示部件3位于手柄1靠近吸收体2的内腔11中。指示芯体32的外周表面被纤维体31包覆，指示芯体32的两端面与的纤维体31两端面齐平，故指示芯体32的长度与纤维体31的长度相等，且指示芯体32和纤维体31同时与吸收体2连通或者连接。
吸收体2由海绵或粘接纤维制成，手柄1底部用粘结剂与吸收体2固定，指示部件3包括纤维体31和被纤维体31包覆的指示芯体32，纤维体31由聚烯烃纤维粘接而成，纤 维体31在干燥的情况下透明度较差，从外界难以透过纤维体31看到指示芯体32的颜色。
当液体吸收装置的吸收体2吸收足够的液体后，部分液体传导给包覆指示芯体32的纤维体31，被液体润湿的纤维体31透明度提高，从外界可以透过透明的手柄1和纤维体31看到指示芯体32的颜色，从而可以判断吸收体2是否已经吸收了足够的液体。
指示芯体32可以被纤维体31完全包覆或部分包覆。指示芯体32的横截面可以为圆形、方形等各种几何形状，也可以为薄片。指示芯体32可以是导液材料如吸水棒，也可以是不导液的材料如塑料棒、海绵棒等。指示芯体32可以制成某种符号或图案，以增加对比度和识别度。
液体吸收装置吸收足够的液体后，将吸收体2插入配套的液体收集容器中，向下按压手柄1，即可将吸收体2中的液体挤出，用于后续测试。
如图3所示，手柄1靠近吸收体2的端部设置有挡板12，挡板12与内腔11对应的位置上设置有可穿过指示部件3的内孔13。挡板12可以与手柄1一体成型，也可以分体成型后，将挡板12和手柄1固定装配在一起。
如此设计，可以方便采集人员的操作，同时更彻底地将吸收体2内吸收的液体挤出，挡板12的内孔13可与手柄1的内腔11的直径相同、位置对应。
图4为图3中指示部件3为圆柱体时的纵剖面图；图5为图3中指示部件3为圆柱体时的横截面图。如图4和图5所示，指示芯体32为圆柱体，吸液指示部件3整体也为圆柱体；纤维体31包覆在指示芯体32的外周，指示部件3的横截面上，指示芯体32的圆周被纤维体31包覆。
图6为图3中指示部件3为长方体时的纵剖面图；图7为图3中指示部件3为长方体时的横截面图。如图6和7所示，指示芯体32为方柱体，指示部件3整体也为方柱体；纤维体31包覆在指示芯体32的四周，指示部件3的横截面上，指示芯体32的四周被纤维体31包覆。
图4到图7仅仅是指示部件3的形状的示例，本领域内的技术人员也可以很容易地想到其它的变形方式，例如，横截面为多边形等方式，这种不背离本发明目的的简单变形均属于本发明权利要求保护范围所涵盖的等同实施方式。
根据本发明的吸液指示部件3，通过纤维体31吸液后透明度提高的特性，使得被纤维体31包覆的指示芯体32的标识部被观察到，便于使用者判断液体是否被准确地收集到采集装置上，或者便于使用者判断是否采集到了足够的液体。
第二实施例
图8为根据本发明第二实施例的液体检测装置的结构示意图。本实施例的结构和第一实施例类似，与第一实施例相同的部分不再赘述。
如图8所示，根据本发明第二实施例的液体检测装置包括手柄1、与手柄1固定连接的吸收体2和装配在手柄1上的指示部件3，其中，指示部件3包括纤维体31和指示芯体32，指示芯体32的外周表面上设置标识部，纤维体31全部或部分包覆指示芯体32的标识部，纤维体31与吸收体2连通，当吸收体2将采集的液体传递给纤维体31时，纤维体31的透明度随着吸收的液体量的增加而提高。
本实施例中，手柄1靠近吸收体2的部分设有沿手柄1轴向方向延伸的内腔11,指示部件3插入内腔11中，内腔11与指示部件3对应的周壁由透明材料制成，指示部件3的纤维体31与吸收体2连通。
吸收体2设置有插孔21，纤维体31延伸并插入插孔21中，在吸收体2被压缩时，纤维体31可被压入内腔11。
如图8所示，手柄1靠近吸收体2的部分设置较深的内腔11，内腔11的深度优先与纤维体31的长度基本相等。
纤维体31具有插入插孔21中的第一部分和可轴向移动地插入内腔11中的第二部分，从而，通过纤维体31将吸收体2与手柄1固定连接。当手柄1的底部与吸收体2相抵接并挤压吸收体2时，纤维体31在内腔11中相对于手柄1轴向移动。即，当吸收体2被施加轴向作用力而轴向压缩时，纤维体31可以被轴向压入内腔11中，从而避免阻碍吸收体2的压缩。
纤维体31的第一部分可以与吸收体2的插孔21以过盈配合的方式进行固定连接，由于吸收体2为可以挤压变形的弹性材质，因此，吸收体2可紧密地包覆住纤维体31，防止发生脱落。
在本实施例中，吸收体2中部的插孔21贯穿吸收体2，纤维体31延伸至吸收体2的底部。通过这样的结构，可以增加纤维体31与吸收体2之间的接触面积，从而增加纤维体31的外周壁和插孔21的内周壁之间的摩擦力，确保纤维体31与吸收体2之间的固定连接。另一方面，通过增加纤维体31与吸收体2之间的接触面积，可以提高吸收体2向纤维体31传导液体的效率，方便对液体样本的吸收程度进行观察。
如图8所示，手柄1靠近吸收体2的端部设置有挡板12，挡板12与插孔21对应的位置上设置有可穿过纤维体31的内孔13。挡板12可以与手柄1一体成型，也可以分体成型 后，将挡板12和手柄1固定装配在一起。
在本实施例中，纤维体31的第二部分与手柄1可以借助纤维体31的第二部分外周面与手柄1的内腔11内壁之间的摩擦力进行固定连接。由于在液体采集的过程中，通常不会施加较大的轴向作用力。因此，仅通过纤维体31的第二部分外周面与内腔11内壁上的摩擦力就足以保证纤维体31与手柄1的可靠连接。当吸收体2的液体释放时，只需在纤维体31的轴向方向施加克服该摩擦力的轴向力时，纤维体31就可以被轴向压入手柄1的内腔11中，从而避免阻碍吸收体2的轴向压缩。
另外，也可将挡板12内的内孔13的直径设置为小于手柄1的内腔11的尺寸，且只利用挡板12的内孔13与纤维体31固定连接，将纤维体31的第二部分与手柄1的挡板连接。挡板12的内孔13与纤维体31的固定连接也可利用内孔13内壁和纤维体31外周面之间的摩擦力进行固定连接。当吸收体2的液体释放时，只需在纤维体31的轴向方向施加克服内孔13内壁和纤维体31外周面之间的摩擦力的轴向力时，纤维体31就可以被轴向压入手柄1的内腔11中，从而避免阻碍吸收体2的轴向压缩。采用该方式，可以降低手柄1的内腔11的加工要求。
手柄1至少在内腔11与纤维体31的第二部分对应的部分采用透明材料，为方便生产，也可全部采用透明材料。
指示芯体32位于吸收体2上方并被纤维体31完全包覆。当吸收体2吸收足量的液体后，部分液体传导至位于手柄1内腔11的纤维体31，纤维体31被湿润后透明度增加，透过手柄1的内腔11和纤维体31可以看到指示芯体32的标识部。
当吸收体2吸收足量的液体后，将液体采集装置的吸收体2插入配套的液体收集容器(未图示)，向下按压手柄1，将吸收体2内的液体挤入至液体收集容器，吸收体2被压缩的同时位于吸收体2内的纤维体31的第一部分上移至手柄1的内腔11中。采用本实施例的液体采集装置，结构简单，显色灵敏，加工方便。
第三实施例
图9为根据本发明第三实施例的液体检测装置的结构示意图；图10为图9中A-A处的截面图。本实施例的结构和第一实施例类似，与第一实施例相同的部分不再赘述。
如图9和图10所示，根据本发明第三实施例的液体检测装置包括手柄1、与手柄1固定连接的吸收体2和装配在吸收体2上的指示部件3，其中，指示部件3包括纤维体31和指示芯体32，指示芯体32的外周表面上设置标识部，纤维体31全部或部分包覆指示芯体 32的标识部，纤维体31同时为吸收体2，当吸收体2吸收液体时，吸收体2的透明度随着吸收的液体量的增加而提高。
本实施例中，手柄1靠近吸收体2的部分设有沿手柄1轴向方向延伸的部分封闭内腔11，吸收体2设置有插孔21，指示芯体32的一部分插入内腔11，另一部分延伸并插入插孔21，当吸收体2被压缩时，指示芯体32可被压入内腔11。
如图9和图10所示，手柄1具有内腔11的部分设置为部分封闭的状态，即在内腔11处的手柄1外壁上形成开口，在图10所示的截面图上显示为圆弧状。
在本实施例中，手柄1优选与挡板12分别成型后组装在一起，手柄1靠近挡板12部分的横截面为略大于半圆的圆弧形，这样可以防止指示芯体32从内腔11中脱出。指示芯体32与挡板12紧密配合，圆柱形指示芯体32被施加足够的轴向作用力的情况下，可以沿手柄1内腔11的内壁上下移动。吸收体2为设置有插孔21的海绵或粘结纤维，插孔21的内径小于指示芯体32的直径，利用海绵或粘结纤维的回弹性将吸收体2与指示芯体32紧配以防止吸收体2与指示芯体32滑脱。
吸收体2中部的插孔21向底部延伸至吸收体2轴向方向的二分之一处。插孔21的深度通常根据将指示芯体32和吸收体2固定连接所需要的摩擦力确定。所需要的摩擦力越大，插孔21的深度可以设置为更深，直至贯穿吸收体2的底部。但插孔21的深度越浅，却可以增大吸收体2的吸收容量。因此，插孔21的实际深度可以根据实际所需的摩擦力进行合理确定。
在本实施例中，无需单独设置纤维体31结构，具体来说，吸收体2除了具备吸收样本液体的功能外，同时具备纤维体31的特征要求，因此，在本实施例中，吸收体2同时也是纤维体31。
指示芯体32一部分插入吸收体2中，指示芯体32为不导液的材料，如塑料棒或海绵棒，也可以为导液的材料，如吸水棒。吸收体2干燥时透明度较低，从外界难以透过吸收体2看到指示芯体32的颜色，当吸收体2吸收足量的液体后，吸收体2的透明度大幅提高，使用者可透过吸收体2直接观察到指示芯体的标识部。
吸收体2吸收足量的液体后插入配套的液体收集容器，向下按压手柄1将吸收体2内的液体挤入至液体收集容器，吸收体2被压缩的同时指示芯体32沿半圆环形的手柄1侧面上移。在本实施例中，只利用吸收体2和指示芯体32组成指示部件3，优化了产品结构，简化了生产过程，降低了生产成本。
第四实施例
图11为根据本发明第四实施例的液体采集装置的结构示意图。本实施例的结构和第一实施例类似，与第一实施例相同的部分不再赘述。
如图11所示，根据本发明第四实施例的液体采集装置包括手柄1、与手柄1固定连接的吸收体2和装配在手柄1和/或吸收体2上的指示部件3，其中，指示部件3包括纤维体31和指示芯体32，指示芯体32的外周表面上设置标识部，纤维体31全部或部分包覆指示芯体32的标识部，纤维体31与吸收体2连通，当吸收体2将采集的液体传递给纤维体31时，纤维体31的透明度随着吸收的液体量的增加而提高。
吸收体2设置有贯穿吸收体2的插孔21，指示芯体32延伸并穿过插孔21后在端部设置有固定板33，在吸收体2被轴向压缩时，指示芯体32可被压入内腔11。
指示芯体32贯穿吸收体2，且指示芯体32的一端从吸收体2的端面伸出，指示芯体32的伸出吸收体2的一端部上形成有固定板33，从而提高吸收体2与指示芯体32间的连接可靠度，防止吸收体2掉落，且手柄1和吸收体2之间不需要通过粘结剂进行固定，连接可靠性更高，并降低生产成本。在本实施例中，手柄1的内腔11中可设置一个台阶，用于对纤维体31进行定位以及固定，且当按压手柄1时，指示芯体可在内腔11内活动，而纤维体31不发生移动。
进一步地，如果选用与制作纤维体31相同的材料制造吸收体2，使吸收体2具有吸水后透明度提高的特性，当吸收体2吸收一些液体后，即可透过吸收体2看到指示芯体的颜色，当吸收体2吸收更多的液体时，位于手柄1部位的纤维体31湿润后变色，从外界可以透过透明的手柄1和纤维体31看到指示芯体32的标识部。如此可随时对样本液体的吸收量进行观察，方便采样。
第五实施例
图12为根据本发明第五实施例的液体采集装置的结构示意图。本实施例的结构和第一实施例类似，与第一实施例相同的部分不再赘述。
如图12所示，根据本发明第五实施例的液体采集装置包括手柄1、与手柄1固定连接的吸收体2和装配在手柄1和/或吸收体2上的指示部件3，其中，指示部件3包括纤维体31和指示芯体32，指示芯体32在外周表面上设置标识部并与手柄1固定连接，纤维体31全部或部分包覆指示芯体32的标识部，纤维体31与吸收体2连通，当吸收体2将采集的 液体传递给纤维体31时，纤维体31的透明度随着吸收的液体量的增加而提高。吸收体2设置有贯穿吸收体2的插孔21，指示芯体32的一端与手柄1固定连接，另一端设置有球缺状固定板33，固定板33穿过插孔21后支撑吸收体2，固定板33最大横截面的直径大于插孔21的直径而小于手柄1的直径。
如图12所示，本实施例中的，述吸收体2同时作为纤维体31，指示芯体32的一端与手柄1的端部固定连接，也可以指示芯体32的一端与手柄1的端部一体成型的方式固定连接。
指示芯体32的另一端设置有固定板33，在本实施例中，固定板33优选为球缺结构，即外周为半球状或者为球冠状曲面，插孔21的内径小于固定板的最大截面直径。在本实施例中，球缺结构是指用一个平面去截一个球体或者椭球体的一部分,不大于一个半球,所得的余下的部分叫球缺结构。
利用纤维体2和插孔21具有的径向伸缩性，固定板33在穿过插孔21时，球缺状的固定板33会撑开插孔21，从而穿过插孔21。当球缺状的固定板33穿过插孔21后，吸收体2因插孔21的内径回缩而被固定板33支撑，从而被牢固地固定在手柄1端面与固定板33之间。
在本实施例中，在制造吸收体2的过程中，可以控制纤维排列方向使吸收体2的轴向压缩强度大于径向压缩强度。当吸收体2吸收足够的液体后，插入如图13所示的配套的液体收集容器4，向下按压手柄1使得吸收体2径向压缩，从而将吸收体2内的液体挤入至液体收集容器4中。值得注意的是，本实施例中的手柄1和指示芯体32在制造时可以一体成型，进一步简化了零部件和组装工艺。
具本而言，如图13所示，与图12所示的液体采集装置配合使用的液体收集容器4包括液体收集室41，以及配置在液体收集室41中的用于径向压缩吸收体2的压缩部。该压缩部包括圆锥形导入口42、设置在导入口42下部的径向压缩腔43和设置在导入口42和径向压缩腔43交界处附近的液体排出口44。液体排出口44与液体收集室41连通。手柄1的直径基本等于吸收体2充分径向压缩后的直径，径向压缩腔43的内径略大于吸收体2充分径向压缩后的直径，固定板33的最大横截面直径小于吸收体2充分径向压缩后的直径。
当吸收体2吸收足够的液体后，手柄1将吸收体2压入液体收集容器4的圆锥形导入口42，吸收体2逐渐径向压缩直到压入径向压缩腔43中。在径向压缩腔43中，吸收体2 得到充分的径向压缩，所吸收的液体被充分释放，并通过液体排出口44流入液体收集室41，从而完成液体的采集工作。
在本实施例中，无需单独设置纤维体31结构，具体来说，吸收体2除了具备吸收样本液体的功能外，同时具备纤维体31的特征要求，因此，在本实施例中，吸收体2同时也是纤维体31。
指示芯体32一部分插入吸收体2中，指示芯体32为不导液的材料，如塑料棒或海绵棒，也可以为导液的材料，如吸水棒。吸收体2干燥时透明度较低，从外界难以透过吸收体2看到指示芯体32的标识部，当吸收体2吸收足量的液体后，吸收体2的透明度大幅提高，使用者可透过吸收体2直接观察到指示芯体的标识部。
采用本实施例的液体采集装置结构简单、组装方便、安全可靠。
上述的五个实施例中，纤维体31由单组份纤维粘结制成，如聚乙烯纤维、聚丙烯纤维、聚烯烃纤维等；优选地，由双组分纤维粘结制成，如聚乙烯/聚丙烯纤维、聚乙烯/聚酯纤维、聚丙烯/聚酯纤维、聚乙烯/尼龙纤维中的一种或一种以上粘接制成；当然，纤维体31还可以由两种以上的纤维混合粘结制成，但纤维体31的材料中至少含有聚乙烯、聚丙烯或聚烯烃中的一种成分，从而实现遇水变透明这一特征。指示芯体可以用有色的纤维粘结制成、或用无色的纤维粘结制成后再用着色剂进行着色，着色剂应着色牢固且不被液体样品溶解、并且不干扰检测装置对待分析物的检测，优选选用颜料，也可以选用对指示芯体着色力强但并不干扰检测的染料。指示芯体可以为各种颜色，指示芯体的颜色较为亮丽，有助于提高在吸收体2吸液润湿时指示部件3的颜色变化的对比度。指示芯体的颜色可以根据使用者的喜好而定。另外，根据使用者的不同喜好，还可进一步在指示芯体上设置识别标志，如在指示芯体的外表面印刷图案、符号或文字，或者，将指示芯体设计成薄片状、符号状、文字状、或图案状等，增加对比度和识别度。
具体实施时，将吸收体2置于采样部位，待吸收体2吸收足够量的液体样本后，与吸收体2相连通的纤维体31会随着吸收量的增加而提高湿润程度，从而逐渐提高透明度，当纤维体31透明度提高后，指示芯体从纤维体31中显色，可直接观察到指示芯体，随后将吸收体2放入液体收集容器中，按压手柄1，将吸收体2内的液体挤入至液体收集容器。综上，本发明涉及的液体采集装置结构简单、使用方便、可靠性高，可快速、明显地对也液体样本是否采集完成做出指示，且不会对液体样本的检测造成干扰，安全可靠，有效克服了现有技术中的种种缺点而具有高度的产业利用价值。
以上对本发明实施例所提供的一种吸液指示部件和液体采集装置进行了详细介绍， 对于本领域的一般技术人员，依据本发明实施例的思想，在具体实施方式及应用范围上均会有改变之处，综上，本说明书内容不应理解为对本发明的限制，凡依本发明设计思想所做的任何改变都在本发明的保护范围之内。
