Description

一种试管塞及使用其的便捷式一次性密闭体液留置器 技术领域
本发明涉及一种塞子,尤其是用于便捷式一种便捷式一次性密闭体液留置器用的塞子以及使用该试管塞的一种便捷式一次性密闭体液留置器。
背景技术
现有技术的试管塞多为实心体,用于将试管中物体或液体留置于试管中,避免试管中的物体或液体外漏。但由于功能单一,存在以下缺陷,如:
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。
即使试管塞上设有十字切口时,由于试条多为柔性材料且比较薄,试条在插入过程中极易弯曲最终导致无法从十字切口处插入,从而无法对试管中的液体进行检测。
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,又能在加注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。
发明内容
本发明的发明目的在于,提供能阻挡住试管中液体或物体外漏的同时,又能对试管中的物体或液体进行检查;并且在加注过程中提高灌注设备与试管的连接稳定性的,检测过程降低检测器将试管中物体或液体携带出试管外造成污染的试管塞。
本发明的发明目的是这样实现的:
一种试管塞,所述试管塞包括本体,所述本体设有阻挡体,所述阻挡体设有活动部和固定部,所述活动部由所述固定部向内延伸形成,所述活动部可相对所述固定部活动,如转动或扭动等;所述活动部具有上表面、下表面以及连接所述上表面和所述下表面的侧面,在所 述活动部的所述上表面上方设有轴向的凹陷。
本发明中所述凹陷可如下:
方式一,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;
方式二,所述凹陷由位于上表面上方的通道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。所述通道用于灌注设备的连接固定。设有通道时,所述通道的内侧壁即是所述本体的内侧壁。
所述阻挡体与所述本体为一体。所述试管塞由弹性材料制成如硅胶、橡胶、TPU、TPE等材料制备。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外力作用,所述活动部向周边展开,形成一个轴向通道,供灌注设备、检测体插拔或供液体流入试管。
进一步地,在所述通道的内侧壁上还可设有凸起。所述凸起用于与灌注设备的下部配合时的密封和定位,同时也用于增加与灌注设备配合的牢固度。一般情况下,灌注设备的下部设有与所述凸起配合的凹槽。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。
进一步地,所述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。即各所述活动部之间不相连。
可以是:当所述本体至少设有两个所述阻挡体时,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:所述活动部之间可相互独立活动,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,所述活动部之间可相互独立活动,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,且在所述本体设有轴向的贯通孔;
可以是,所述本体设有至少两个阻挡体,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。
相邻所述活动部的侧面之间间隙大于等于0.3mm且小于等于1.8mm。所述活动部的侧面之间间隙可以形成为十字形,三爪形,一字形或不规则形,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本体的内侧壁之间设有间隙,所述间隙大于等于0.3mm且小于等于1.8mm,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触所述本体的内侧壁。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,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大于等于2㎜2小于35㎜2最佳。
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。总之,所述凹陷由所述活动部的上表面和通道的内侧面共同形成,上表面可以是平面、斜面、也可以曲面等等。
本发明的另一发明目的在于,提供一种便捷式一次性密闭体液留置器。
本发明的发明目的是这样实现的:
一种便捷式一次性密闭体液留置器,包括试管组件和液体导流装置,所述试管组件包括试管塞和试管;所述试管设有开口端和管腔;所述试管塞设置于所述试管的开口端;所述试管塞包括本体,所述本体设有阻挡体,所述阻挡体设有活动部和固定部,所述活动部由所述固定部向内延伸形成,所述活动部可相对所述固定部转动;所述活动部具有上表面、下表面以及连接所述上表面和所述下表面的侧面;所述液体导流装置包括本体乙,所述本体乙包括环形侧壁和导液通道;所述导液通道设有进液口和出液口;所述试管塞设有轴向的凹陷;所述凹陷位于所述活动部的上表面上方;位于的出液口一端的所述本体乙与所述凹陷配合且抵压于所述活动部的上表面;所述液体导流装置的下部与所述试管组件可拆卸配合,所述出液口与所述管腔连通。
进一步地,所述液体导流装置还设有排气通道,所述排气通道设有出气口和排气口,所述排气口与所述出液口位于本体乙的下部,所述排气通道与所述导液通道互不相通。所述导 液通道和所述排气通道与所述液体导流装置可以为一体成型;也可是所述导液通道与所述液体导流装置为一体成型,所述排气通道与所述液体导流装置分体配合。

1、本发明的凹陷50对检测装置(如试条等)插入时具有导向作用,使用者无需对准贯通孔20,只需将检测装置的端部对准凹陷就可实现便捷的插入。
2、本发明的凹陷50降低了检测装置插入时的阻力,使得检测装置更容易从贯通孔20插入。
3、当将检测装置从贯通孔20中取出时,一方面由活动部上表面围合形成的凹陷,不易将试管中的带出液体;当凹陷由通道的内侧壁和活动部上表面围合形成时,由于通道具有一定的高度,可更有效地避免将试管中的带出液体,从而降低了污染。
4、当试管中灌有液体后,倾斜试管时,液体挤压本发明的活动部,本发明的凹陷50可有效地阻止活动部变形,从而实现对液体的封堵。
5、本发明在应用过程中,即试管中未灌注液体时,试管、灌注设备与本发明长时间配合固定,只有当试管中灌注液体后才将灌注设备移开,现有技术的试管塞由于长期处于变形状态很难恢复,而本发明由于设有凹陷可使活动部及时恢复,从而实现对液体的封堵。
6、灌注设备的下部与试管塞配合时,试管塞上的凸起与灌注设备下部上的凹槽相配合,具有较好密封效果;另一方面,灌注设备与试管塞的配合时,试管塞上的凸起卡设于灌注设备的下部的凹槽内,可有起到配合进行定位的作用,也可增加配合的牢固度。
7、当本发明试管塞与灌注设备配合时,灌注设备下部的外侧壁可以非常便捷地和试管塞通道内侧壁配合固定且配合稳定不易脱落。

本发明中试条插入时,单次插准最小阻力位置准确度为99%。
结论:本发明在凹陷50的导向的作用下,能快速准确找到最小阻力位置,插入准确度明显优于现有技术。
试条插入时受到的最小阻力:
现有技术中试条插入时,受到的最小阻力0.06N。
本发明中试条插入时,受到的最小阻力0.01N。
结论:本发明在试条插入时受到阻力明显小于现有技术产品,便捷高效。
试条能顺利插入所能承受的最大阻力:
现有技术中试条插入时,试条能顺利插入能承受的最大阻力0.07N。
本发明中试条插入时,试条能顺利插入能承受的最大阻力0.07N。
结论:当阻力大于0.07N时,试条插入时会弯曲变形,导致不易插入。
试条能单次顺利插入塞子进入试管的成功率:
现有技术中试条能单次顺利插入试管塞的切口,进入试管的成功率为7%。
本发明中试条能单次顺利插入试管塞的贯通孔,进入试管的成功率为100%。

结论:本发明在试条抽出时受到阻力明显小于现有技术产品。
试条抽出时,将试管中液体带出活动部的概率:
现有技术中试条抽出时液体带出活动部概率83%。
本发明中试条抽出时液体带出活动部概率12%。
结论:使用本发明测试过程中试条抽出时将液体带出活动部概率明显小于现有技术。
试条抽出时液体带出试管塞外概率:
现有技术中试条抽出时将液体带出试管塞外部的概率75%。
本发明中试条抽出时将液体带出试管塞外部的概率2%。
结论:使用本发明测试过程中,试条抽出时将液体带出试管塞外的概率明显小于现有技术,使用本发明较使用现有技术更干净卫生。
试管塞和灌注体配合情况:
现有技术中,试管塞和灌注体(如取液件)无法固定配合,使用时需要二人配合,如单人操作极易发生取液件的掉落。
本发明中设有用于与灌注体(如取液件)配合使用的通道30,可使取液件容易固定,操作时只要单人即可,本发明能有效便捷地将试管和取液件连接固定。
