Description

自动闭合式中段尿液收集器 技术领域
本发明涉及医用检验辅助器具，具体地涉及一种自动闭合式中段尿液收集器。
背景技术
目前用于医院检验的医用尿液取样器具大多为一次性尿杯，或者是一次性尿杯加一个试管，在实际使用时存在如下缺陷：现有的尿液取样器直接将尿液通过导管导入试管，但是实际上小便开始的部分尿液为前段尿液，并不符合《中华人民共和国卫生行业标准Ws/T348—011尿液标本的收集及处理指南》中关于中段尿采集标准的要求，即部分前段尿液也被导入试管送去检验，导致检验结果不准确。
发明内容
针对现有技术的上述不足，本发明提供了一种自动闭合式中段尿液收集器，利用插管内径较小且有一定高度的特征，可以通过插管内存有的尿液在先期流入废液腔内的前段尿液与后期中段尿液之间形成隔离屏障，将前段尿液闭合在废液腔内，保证中段尿液流入试管内，确保检验结果的准确性。
一种自动闭合式中段尿液收集器，包括上端开口(或上端敞口)的尿杯和与所述尿杯连通的导管，所述尿杯的底部设有废液进口，所述废液进 口向下竖直延伸形成与废液腔连通的插管(即所述废液进口向下竖直延伸形成与设置于所述尿杯下方的废液腔连通的插管)，尿杯的内侧壁(或内侧壁上)设有进液口以及将所述进液口遮挡的遮罩件，所述遮罩件的下部设有开口，以使得后续中段尿液通过所述开口流入所述进液口，所述插管在填满前期流入的尿液后形成隔离屏障，将先期流入所述废液腔内的前段尿液闭合在所述废液腔内。
可选地，所述插管的直径为2-30mm，长度为5-50mm。进一步地，所述插管的直径优选为5-25mm，更优选为10-20mm；所述插管的长度优选为10-40mm，更优选为20-30mm。
可选地，所述废液腔的容积为5-50ml。进一步地，所述废液腔的容积优选为10-40mm，更优选为20-30mm，最优选为10-20mm。
进一步地，所述导管内设有与外部空气连通的导气腔和与所述进液口连通的导液腔。
进一步地，所述尿杯的外侧壁(或外侧壁上)设有竖直向上的导气管，所述导气管与所述导气腔连通。
更进一步地，所述遮罩件为一前斜面、左、右三面设有围挡而底面设有所述开口的结构。
可选地，所述遮罩件为弧形结构。
可选地，所述尿杯的内侧壁(或内侧壁上)设有沿侧壁方向向下的滑道，所述遮罩件滑动设于所述滑道上(即所述遮罩件可滑动地设置于所述滑道上)。
可选地，所述遮罩件与尿杯的内侧壁通过卡接或插接方式固定(即所述遮罩件通过卡接或插接的方式固体于所述尿杯的内侧壁上)。
可选地，所述插管与废液腔为一体成型。
本发明通过在尿杯中设置将进液口遮挡的遮罩件，以及与尿杯底部的废液进口连通的废液腔，可将排尿初期的废尿液收集在废液腔中，而将真正需要采集的中段尿液通过进液口流入导管，最后进入导管所插入的试管中，因插管内径足够小且具有一定高度，利用插管内存有的尿液作为隔离屏障，将初始阶段流入废液腔内的前段尿液闭合在废液腔内，后期进入的中段尿液完全留存在试管内，以确保检验结果的准确性。
根据本发明提供的自动闭合式中段尿液收集器，能够带来至少以下有益效果之一：
1、能够准确收集中段尿液或尿样，使其不与非检测物接触，保证了检验结果的准确性，符合国家卫计委规定的尿液标本采集技术要求，使用时自动去除了前段废尿液，自动保留中段尿液标本；
2、储存了前段尿液或尿样，通过科学、合理地设计了插管的内径(直径或口径)和高度(或长度)而将前段尿液或尿样封闭在废液腔内，无外溢和异味散发，降低了尿样交叉污染的风险，符合国家卫生部对尿样采集环节的要求；
3、使用者无需指导即可正确操作，操作卫生、简单、快捷，由于本发明提供的自动闭合式中段尿液收集器设有与导管所插入的试管相连通的并彼此相连通的导气腔和导气管，即设有空气调节装置，所以可快速地(通常3、4秒钟即可)完成中段尿液或尿样的采集。
附图说明
为了更清楚地说明本发明具体实施方式或现有技术中的技术方案，下面将对具体实施方式或现有技术描述中所需要使用的附图作简单地介绍。显而易见地，下面描述中的附图是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

附图标记：尿杯1，废液进口2，滑道3，遮罩件4，插管5，废液腔6，导管7，止挡件8，进液口9，导气管10，开口11，导气腔71，导液腔72。
具体实施方式
下面参照附图详细介绍本发明的示例性实施例。提供这些示例性实施例的目的是为了使得本领域普通技术人员能够清楚地理解本发明，并且根据这里的描述能够实现本发明。附图和具体实施例不旨在对本发明进行限定，本发明的范围由所附权利要求限定。
参照图1-4，本发明实施例提供了一种自动闭合式中段尿液收集器，其包括上端开口或上端敞口的尿杯1、与该尿杯1连通的导管7和设置于该尿杯1下方的废液腔6，上述尿杯1的底部设有废液进口2，该废液进口2向下竖直延伸形成与上述废液腔6连通的插管5，该插管5的一端与废液进口2连通，其另一端插入上述废液腔6中，上述插管5与废液腔6的管口适配，可如图3所示设计为下端具有两个插销的管状结构，插入时两个插销受压而相向靠近，插入上述废液腔6的上端管口后，两个插销向外张紧，从而使得插管5的外壁与废液腔6的管口内壁紧贴，以防止液体从废液腔6的管口与插管5之间出现的缝隙而溢出。在另一实施例中，插管5与废液腔6也可为一体成型。
参照图3，上述尿杯1的内侧壁(或内侧壁上)设有进液口9以及将该进液口9遮挡的遮罩件4，该遮罩件4的下部设有开口11，以使得后续中段尿液通过该开口11流入上述进液口9。即，参照图3，尿杯1的内侧壁(或内侧壁上)设有与导管7连通的进液口9，而进液口9正好被遮罩件4盖住，后续中段尿液可通过所述开口11流入进液口9。该上述尿杯1的内侧壁(或内侧壁上)设有沿侧壁方向向下的滑道3，该滑道3上滑动设有遮罩件4(即该遮罩件4可滑动地设置于上述滑道3上)。如图1所示，所述遮罩件4可为一前斜面、左、右三面设有围挡而底面设有上述开口11的结构。在其他实施例中，所述遮罩件4的结构也可设计成其他结构，例如能盖住或遮挡住进液口9的弧形结构。需要注意的是，上述遮罩件4并不局限于上述结构(即一前斜面、左、右三面设有围挡而底面设有上述开口11的结构，以及弧形结构)，只要能将进液口9遮挡住，防止尿液进入尿杯1 时溅入进液口9即可。在前段尿液通过废液进口2、插管5进入废液腔6时，尿液滴溅时会被遮罩件4遮挡而不会通过进液口9进入导管7，保证采集中段尿样的准确性。所述遮罩件4也可与尿杯1的内侧壁通过卡接、插接等其他方式固定(即所述遮罩件4也可通过卡接、插接等其他方式固定于上述尿杯1的内侧壁上)，也可与设为尿杯1的内侧壁一体成型(即也可与上述尿杯1的内侧壁设为一体成型)。
参照图3及图4，导管7上设有止挡件8，该止挡件8设置于上述导管7的外周壁上，主要是为了与试管插接时起到对试管的限位作用。所述导管7内设有与外部空气连通的导气腔71和与上述进液口9连通的导液腔72，所述导气腔71和所述导液腔72在导管7内分隔设置，上述尿杯1的外侧壁(或外侧壁上)设有竖直向上并与外部空气连通的导气管10，所述导气管10与所述导气腔71连通(即导气管10的一端与外部空气连通，其另一端与导气腔71连通)，从而实现导气腔71与外部空气连通，且导气腔71即使有尿液回流，因为导气管10为竖直向上设置，所以也不会从导气管10溢出。
需要说明的是，上述导气腔71的一端与导气管10连通，其另一端与导管7所插入的试管连通，从而实现了导管7所插入的试管与外部空气连通，相当于给收集尿液或尿样的试管设置了空气调节装置，以使得快速地(通常3、4秒钟即可)完成尿液采集。
在使用时，尿液流入尿杯1，初始阶段的尿液会通过废液进口2、插管5进入废液腔6进行暂时收集，废液腔6的容积大小可根据实际情况设置，本实施例设置为5-50ml(进一步地，该废液腔6的容积优选为10-40mm， 更优选为20-30mm，最优选为10-20mm，例如5ml、10ml、15ml、20ml、25ml、30ml、35ml、40ml、45ml、50ml等)，这样大约5-50ml的前段尿液就收集在废液腔6中，后续的尿液在废液腔6装满前段尿液后，进而填满插管5，插管5被尿液填满后，后续的中段尿液自然通过遮罩件4的开口11、进液口9、导管7的导液腔72进入试管，从而实现中段尿液的准确采集。
插管5的直径可设为2-30mm，长度为5-50mm。该插管5的直径优选为5-25mm，更优选为10-20mm，例如2mm、5mm、10mm、15mm、20mm、25mm、30mm等。该插管5的长度优选为10-40mm，更优选为20-30mm，例如5mm、10mm、15mm、20mm、25mm、30mm、35mm、40mm、45mm、50mm等。上述插管5在填满前期流入的尿液后通过科学、合理地设计的插管5的内径或直径或口径以及其高度或长度而形成了隔离屏障，将先期流入上述废液腔6内的前段尿液或尿样闭合或封闭在该废液腔6内。具体地，当尿液导入时，中段尿液完全充满插管5内，因插管5的口足够小且其具有一定高度，则该插管5内的尿液自动起到可完全隔离并阻挡废液腔6中废尿回流并将之完全闭合在废液腔6内的作用，使剩余的中段尿液全部通过进液口9流入导管7，最后进入导管所插入的试管中，从而将初始阶段的前段尿液保留在废液腔6中，而提供检验所需的中段尿液则完全留存或保留在该试管内。
参照图1和图3，上述尿杯1的周壁并不是等高的，其靠近导管7的一侧的周壁要高于远离导管7的一侧的周壁，以在采集取样完成后有利于倾倒剩余废液，避免污染环境。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何属于本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
