Description

一种取液件与试管组件的配合结构 技术领域
本发明涉及医疗器械，尤其涉及用于采集体液用的装置。
背景技术
现有技术中，取液件与试管的配合结构为取液件的下部与试管插接配合，
其一，试管加注液体时，灌注设备与试管为硬连接，二者的连接配合的密封性和稳定性不够，液体容易泄露且灌注设备容易掉落。为此，在灌注过程中，需要二人配合，造成操作上的繁琐和不便。
其二，一旦试管塞封堵住试管的开口端后，如需对试管内的物体或液体检测，需要将试管塞取出后才能实施；操作步骤繁多。
其三，试管加注液体结束后，将灌注设备从试管开口部移开时，灌注设备底端容易将试管中的液体带出，容易污染试管外部。
其四，当液体通过取液件注入试管中时，无法对注入液体的高度进行控制，只有试管中的液体注满才不继续存储液体，此时，当试条或检测吸管插入试管时，容易导致试管中的液体溢出，造成污染。
因而如何提供一种既能保证灌注设备和试管的配合稳定，液体不易泄露，能在加注液体的同时对试管的开口部进行封堵，又能降低污染，且可无需取下试管塞即可对试管中液体进行检测的试管塞，成为业界亟待解决的技术难题。

上述方案中，所述试管塞由弹性材料制成如硅胶、橡胶、TPU、TPE等材料制备。在所述活动部的所述上表面上方的轴向的凹陷由下列方式形成：
一、所述凹陷由所述活动部的所述上表面围合而成，即由固定部根部与活动部端部之间的高度差形成；可以是所述活动部的端部低于所述活动部的根部；也可是所述活动部的厚度由根部向端部方向减小，所述活动部的厚度为所述活动部的上表面至所述活动部的下表面的距离。所述活动部的厚度可以由所述活动部的根部向所述活动部的端部方向渐进式减小，也可是阶梯式减少，或其他减小方式。上表面可以是平面、斜面、也可以曲面等等。
二、或所述凹陷由位于所述活动部的上表面上方的通道甲的内侧壁与所述活动部的所述上表面围合而成，此时的活动部的上表面可以是平面、斜面或曲面。所述通道用于 取液件的连接固定。设有通道甲时，所述通道甲的内侧壁即是所述试管塞本体的内侧壁。
进一步地，所述试管塞的所述通道甲的内侧壁上还可设有环状凸起乙。所述环状凸起乙用于与取液件的下部配合时的密封和定位，同时也用于增加与取液件配合的牢固度。可以是取液件的下部外缘上设有与所述通道甲的内侧壁上的环状凸起乙配合的环状凹槽甲，所述取液件下部外缘上的环状凹槽甲与所述试管塞的通道甲的内侧壁上的环状凸起乙配合；也可是所述取液件下部外缘与所述试管塞通道甲的内侧壁上的环状凸起乙配合；还可在所述本体的外侧壁上设有凸起。所述本体的外侧壁上的所述凸起用于与试管配合时增加配合的牢固度和以及配合定位。所述凸起可以是环状、点状或螺旋状等等。
所述试管塞具有一关闭态和一打开态。当试管塞处于关闭态时，所述阻挡体的活动部不受外力作用处于自然状态。当试管塞处于打开态时，所述阻挡体的活动部受到取液件下部的作用，所述活动部向周边展开，形成一个轴向通道乙，或供液体流入试管或供检测设备取样。其中试管塞本体的阻挡体的个数可以是1、2、3、4等等。
当所述本体至少设有两个所述阻挡体，所述阻挡体的活动部相互独立，各所述活动部的侧面之间抵接或各所述活动部的侧面之间设有间隙等。
可以是：所述阻挡体的活动部相互独立，所述本体设有轴向的贯通孔。
可以是：所述活动部与所述活动部之间设有切线；所述切线由所述活动部的侧面抵触形成。
可以是，所述活动部与所述活动部之间设有切线，所述切线由所述活动部的侧面抵接形成，且在所述本体设有轴向的贯通孔；
可以是，所述活动部的侧面之间设有间隙，所述间隙形成轴向的贯通孔。
可以是，所述活动部之间可相互独立活动，所述活动部侧面之间抵接。
相邻所述活动部的侧面之间间隙大于等于0.06mm且小于等于1.8mm，优选相邻所述活动部的侧面之间间隙大于等于0.06mm且小于等于0.3mm。侧面之间间隙可以形成为X形、十字形、Y形、一字形、T字型或不规则形等，间隙的形状依据所述活动部的数量而定。
当只有一个阻挡体时，所述阻挡体的活动部与所述通道甲的内侧壁之间设有间隙，所述间隙大于等于0.06mm且小于等于1.8mm，优选所述阻挡体的活动部与所述通道甲的内侧壁之间设有间隙大于等于0.06mm且小于等于0.3mm。所述间隙形成轴向的贯通孔。也可以是所述阻挡体的活动部的侧面抵接所述通道甲的内侧壁。此时活动部的上表面可 以是平面，斜面、也可以是曲面。
试管中灌注液体后，倒掉取液件中多余的液体，将取液件与试管组件分离，试管内液体在所述贯通孔处接触外部的气体，即在所述贯通孔的表面形成液膜，液膜是液体跟气体接触的表面存在一个薄层，叫做表面层，表面层里的分子比液体内部稀疏，分子间的距离比液体内部大一些，分子间的相互作用表现为引力。轴向贯通孔利用了液体表面具有张力的特性，通过液膜阻挡液体流至外部，从而实现防漏。贯通孔与气体接触的面积越小，形成液膜的防漏效果越好，反之就越差；所述贯通孔的截面积最小处大于等于2㎜2小于35㎜2，优选所述贯通孔的截面积最小处大于等于3㎜2小于18㎜2。
上述方案中，取液件的所述下出口低于试管塞下部的最低处，所述取液件的通道下出口至少低于试管塞下部的最低处1mm，但不低于所述试管塞下部的最低处20mm。优选所述取液件的通道下出口至少低于试管塞下部的最低处2mm，但不低于所述试管塞下部的最低处12mm。更佳为所述取液件的通道下出口至少低于试管塞下部的最低处3mm，但不低于所述试管塞下部的最低处8mm。
当所述取液件的通道下出口低于试管塞下部的最低处1mm、2mm、3mm、4mm、5mm、6mm、7mm、8mm、9mm、10mm、11mm、12mm、13mm、14mm、15mm、16mm、17mm、18mm、19mm、20mm等时，液体自取液件灌注至试管的过程中，当试管中的液面封堵住取液件的通道下出口时，因试管中残留气体压力，致使取液件内液体停止流入试管，从而有效地控制试管内液面高度(可以是液面封堵住导液通道的出液口，也可以是液面封堵住排气通道的排气口，还可以是液面同时封堵住导液通道的出液口和排气通道的排气口)，液面距离试管塞的下端仍可保持一定的距离。当取液件移开后，试条或检测用吸管等物品再次插入试管中进行检测时，可确保插入的物品不会立即将液面抬高至试管塞的下端，从而造成液体外溢。另外，检测吸管在试管中吸排液体，使液体混合均匀的过程中，需先将吸管中的气体排除，如果试管中液面过高或超过试管塞的下端，吸管在吸排液时，排除的气体会推高液面使液体溢出，因而，液面低于试管塞一定高度，在吸管吸排液体或排气时，可确保气体先排出避免排气导致液面提高超过试管塞的下端，使试管中的液体溢出，又能保证试条和检测仪检测时所需液面高度。
一般情况，试管管腔高度不小于90mm且不大于115mm。试管开口端的直径大于等于12.5mm且小于等于16mm。
上述方案中，所述通道下出口至试管管口的距离不小于试管管腔高度的5％，不大于 试管管腔高度的35％。优选所述下出口至试管管口的距离不小于试管管腔高度的10％，不大于试管管腔高度的25％。较佳所述下出口至试管管口的距离不小于试管管腔高度的15％，不大于试管管腔高度的22％。

当所述通道包括导液通道和所述排气通道时，所述通道中设有隔断，所述隔断将所述通道分隔为互不相通的导液通道和排气通道。其中，所述隔断可以是：
一、所述隔断为连接导液通道和排气通道的连接部，且连接部的底端不高于所述出液口和/排气口。可以是连接部的底端同时低于所述出液口和排气口；或连接部的底端低于排气口，但不高于所述出液口；或连接部的底端同时与所述出液口和排气口齐平。
二、所述隔断为连接导液通道和排气通道的连接部，且连接部上设有向内凹陷甲。
所述出液口和所述排气口位于所述取液件的下部；所述取液件的下部与所述试管组件配合固定时，液体可通过所述导流通道顺利流入所述试管的管腔中。其中，导流通道截面积最小处大于等于3mm2小于等于18mm2；排气通道截面积最小处大于等于3mm2小于等于18mm2。当所述取液件与所述试管组件配合固定或分离时，所述试管塞的阻挡体产生形变。所述取液件与所述试管组件配合固定或分离时，所述管腔中的液体均不易从管腔中流出。其中，导流通道截面积最小处指出液口的截面积；排气通道截面积最小处指排气口的截面积。
优选所述导流通道截面积最小处大于等于4mm2小于等于12mm2；所述排气通道截面积最小处大于等于4mm2小于等于12mm2。当导流通道截面积最小处大于等于4mm2小于等于12mm2；所述排气通道截面积最小处大于等于4mm2小于等于12mm2时，可减低液体堵住所述取液件的排气口的可能，造成所述取液件中液体流动不畅的情况；同时也能减轻因间歇性采液导致所述取液件导液不畅的情况；倾倒所述取液件中多余液体的过程中，在所述出液口、所述排气口处形成液膜，从而降低所述试管中的液体从出液口或排气口流出去的概率。其中，在所述导流通道截面积最小处不大于10mm2时，优选所述排 气通道截面积最小处不小于所述导流通道截面积最小处。
其中，所述排气通道截面积最小处指排气口的截面积，导流通道截面积最小处指的是出液口的截面。
当导流通道最小处截面积大于10㎜2时，优选排气通道截面积最小处不低于导流通道截面积最小处的25％，使取液件在采集液体的过程中导液顺畅且快速。
取液件的通道下出口的外周还可设有遮挡体，所述遮挡体用于阻挡取液件通道外的液体溅洒至试管外壁。遮挡体的高度不低于试管高度的70％。
所述遮挡体与所述取液件可以是一体成型，也可是分体配合固定。所述遮挡体位于试管的外围。所述遮挡体可以是位于所述取液件的上部、中部、下部、外围、上部及外围、中部及外围或下部及外围。所述取液件还设有手柄，所述手柄外侧设有防护侧壁，所述防护侧壁用于避免液体溅落于手柄上。所述遮挡体包括遮挡侧壁，所述遮挡侧壁环绕试管小于等于360°。当所述遮挡侧壁环绕试管360°时，可在所述遮挡侧壁上设有观察、扫描用的视窗；或者将所述遮挡侧壁用透明材料制备,采用透明材料时可不设有用于观察、扫描用的视窗。
进一步地，所述遮挡体包括活动部甲和固定部甲，所述活动部甲与所述固定部甲活动连接；所述固定部甲与所述取液件的下部固定连接或一体成型。
进一步地，所述活动部甲与所述固定部甲套接，且所述活动部甲在所述取液件轴向位置改变至一定角度时在自有重力的作用下，可相对所述固定部甲在轴向自由滑动。还可在活动部甲的侧壁上设有轴向的收缩槽。
所述遮挡体包括活动部乙和固定部乙，所述活动部乙相对所述固定部乙可转动，所述活动部乙与所述固定部乙的横截面均为弧状，所述固定部乙与所述取液件的下部固定连接。活动部乙相对所述固定部乙转动，其中活动部乙和固定部乙之间可以存在部分的叠合，活动部乙和固定部乙围合后共同环绕试管360°。
上述方案中，与所述活动部的上表面紧密配合处的所述B部的外径大于等于5.5mm且小于等于11mm。所述B部的外径大于等于5.5mm且小于等于11mm便于阻挡体的活动部在取液件与试管组件分离后快速恢复至取液件未与试管组件配合时的初始状态。
当采集液体结束后，掉到所述取液件中多余液体，将所述取液件和所述试管组件分离后，所述试管中液面高度距离试管塞底端面的距离大于等于3.5mm且小于等于15mm。优选所述试管中液面高度距离试管塞底端面的距离大于等于4.5mm且小于等于12.5mm。
上述方案中，试管塞下部的最低处有二：
一、为取液件与试管组件配合时，阻挡体的活动部向下打开后，活动部的最低点为试管塞下部的最低处；
二、为取液件与试管组件分离时，阻挡体的活动部处于初始状态，活动部的下表面最低点处为试管塞下部的最低处。
上述方案中，可以存在以下几种使用方式：
使用方法一：初始状态时，所述取液件的下部与所述试管组件配合固定，所述取液件的下部外缘与通道甲的内侧壁配合，取液件的出液口位于所述阻挡体的活动部的上表面的上方。取液件的下部的底端抵触所述活动部的上表面，或取液件的下部的底端与所述活动部的上表面不接触。当需要采集液体时，使取液件的下部抵压试管塞的阻挡体的活动部，使活动部向下(液体流动的方向)且向外展开，使取液件的下部外缘与所述活动部的上表面形成紧密配合。待采集液体结束后，倒掉取液件中多余的液体，将取液件与试管组件分离，留试管组件供检测设备或人员调用。
使用方法二：初始状态时，所述试管组件与所述取液件相互分离；采集液体时，将所述取液件与所述试管组件配合固定。即所述取液件的下部外缘与试管塞的通道甲的内侧壁配合，取液件的下部抵压试管塞阻挡体的活动部上表面，使活动部向下(液体流动的方向)且向外展开，取液件的下部外缘同时与通道甲的内侧壁和所述活动部的上表面形成紧密配合，所述取液件的出液口与试管管腔连通。待采集液体结束后，倒掉取液件中多余的液体，将取液件与试管组件分离，留试管组件供检测设备或人员调用。
使用方法三：初始状态时，所述取液件与所述试管组件配合固定。即所述取液件的下部外缘与试管塞的通道甲的内侧壁配合，且取液件的下部外缘与试管塞阻挡体的活动部上表面紧密配合，使活动部向下(液体流动的方向)且向外展开，所述取液件的出液口与试管管腔连通，所述下出口不高于试管塞下部的最低处。待采集液体结束后，倒掉取液件中多余的液体，将取液件与试管组件分离，留试管组件供检测设备或人员调用。
本发明具有以下优点：
1、可以准确将试管中的液面限定在试管管腔内的特定位置，此位置能保证试条和检测仪检测时所需的液面高度。
2、可以有效减少或防止液体在灌注过程、试条插入检测或检测仪吸管插入试管 中、检测仪吸管对试管内液体进行均匀混合及汲取的过程中液体从管腔中溢出。
3、本发明的试管塞的凹陷对试条插入时具有导向作用，也降低了试条插入时的阻力，使用者只需将试条的端部对准凹陷就可实现便捷的插入。
4、当从试管组件中将试条从中取出时，试管塞的凹陷和通道结构可有效避免试条或检测仪吸管将试管中的液体带出，还能刮掉试条检测块上的多余液体即使试条裹挟的液体滴落时，滴落的液体也会被引导回流至试管中，有效地避免了污染。
5、本发明的取液件的下部与试管塞的凹陷和通道配合时，密封性更好，避免漏液。
6、商品自出厂至消费者使用，此阶段取液件与试管组件长时间配合，现有技术的试管塞的阻挡体由于长期处于变形状态，阻挡体长时间疲劳后，很难恢复至初始状态，导致防漏能力降低。而本发明的试管塞的凹陷结构，可提高阻挡体的恢复力，可使试管塞的活动部及时恢复，从而实现对液体的封堵。
7、本发明在灌注完液体倒掉取液件内多余液体时和试管和取液件分离后试管内液体都不易流出。
