Abstract

本发明公开了一种静脉接入装置，该静脉接入装置可以包括针座，所述针座具有倾斜桨状握把以便于导管以低角度插入。所述倾斜桨状握把还可以使插入过程中延长管或稳定平台可能造成的任何干涉最小化。通过利用倾斜桨状握把，可以插入导管同时将稳定平台保持在基本平行于病人皮肤的方位上。还有，在延长管可以平行于稳定平台延伸的情况下，倾斜桨状握把可以在插入过程中防止延长管伸入病人皮肤中。这将防止稳定平台和/或延长管卡在病人皮肤上或者以其他方式阻碍导管的平滑插入。

背景技术
当IV(静脉)接入装置被确认为“封闭的”或“整合的”时，一般指的是该装置构造成在导管插入期间防止血液从该装置漏出。一般地，这种IV(静脉注射)接入装置是通过将延长装置与导管适配器结合在一起来实现这一点的。
图1示出了现有技术的一种封闭的IV接入装置100的示例。该装置100包括导管适配器101、针座102、延长管103和夹具107，导管101a从所述导管适配器101延伸，针102a从所述针座102延伸，所述延长管103一端连接到导管适配器101并且包括连接到另一端的Y形适配器104，所述夹具107用于阻挡或限制流体流过延长管103。Y形适配器104包括端口105和气孔塞106。装置100可通过将流体流阻挡元件(例如隔膜或气孔)结合到该装置的每个外部开口中而成为封闭系统，诸如结合到导管适配器101的近端部中以及结合到适配器104中的任何端口中。
通常，当使用IV接入装置(诸如接入装置100)时，临床医生会用拇指在顶部以及一个或多个手指在下面握住导管适配器101和/或针座102。还有，如果导管适配器101包括稳定平台，诸如图1中示出的，临床医生可以握住稳定平台的与延长管103相对的一部分。当使用这种插入技术时，难于以关于病人皮肤以低角度定位导管适配器101——需要做一些事情来获得导管101a合适放置——因为临床医生的手指阻止导管适配器101靠近病人皮肤定位。
为了在握住导管适配器101的稳定平台的同时使插入角度最小，临床医生可以沿逆时针方向(从临床医生的视角来看)转动导管适配器101，从而在稳定平台与病人皮肤之间形成可在插入过程中定位临床医生的手指的空间。然而，以这种方式转动导管适配器101会使稳定平台的包括延长管103的另一侧倾斜到病人皮肤中。在这种情况下，稳定平台和延长管可能拖拽病人皮肤或者卡在病人皮肤上，从而难于实现平滑插入。
发明内容
本发明总体上涉及一种IV接入装置，所述IV接入装置包括针座，所述针座具有倾斜桨状握把以便于导管以低角度插入。所述倾斜桨状握把还可以将在插入过程中延长管或稳定平台可能造成的任何干涉减到最少。通过使用倾斜桨状握把，可以在将稳定平台保持在基本平行于病人皮肤的方位的同时插入导管。还有，因为延长管相对于稳定平台平行地延伸，所以延长管在插入过程中不会延伸到病人皮肤中。这防止延长管卡在病人皮肤上或者防止对导管的平滑插入造成阻碍。
根据本发明的一种导管适配器可以包括稳定平台(例如，翼部)，所述稳定平台可以形成可平坦地放在病人皮肤上的表面。所述稳定平台可以是柔性的或者是可重新定位的，以允许在导管插入过程中使稳定平台的至少一侧以一角度取向。为了将稳定平台以一角度取向，所述针座可以包括倾斜桨状握把，所述倾斜桨状握把设计成当针座连接到导管适配器时定位在稳定平台下方。由于稳定平台的柔性或可重新定位性，倾斜桨状握把将稳定平台提升以将其定位在相应角度处。临床医生于是可以在插入导管时握住倾斜桨状握把和倾斜的稳定平台。由于这些元件的倾斜，在插入过程中可以将导管适配器保持在基本平坦方位上。更特别地，在插入过程中将与倾斜桨状握把相对的稳定平台以及将延长管保持在基本平坦的方位上，从而将这些元件会拖拽病人皮肤或戳坏病人皮肤的可能性最小化。
在一个实施例中，本发明实施为一种IV接入装置，所述IV接入装置包括：导管适配器，导管从导管适配器向远侧延伸，所述导管适配器包括翼部；以及针座，针从针座向远侧延伸，所述针座构造成连接到导管适配器使得针延伸穿过导管。所述针座还包括桨状握把，所述桨状握把构造成当将针座连接到导管适配器时邻近所述翼部定位，所述桨状握把以一角度取向。
在另一个实施例中，本发明实施为一种IV接入装置，所述IV接入装置包括：导管适配器，导管从导管适配器向远侧延伸，所述导管适配器包括翼部；以及针座，针从针座向远侧延伸，所述针座构造成连接到导管适配器使得针延伸穿过导管。所述针座还包括桨状握把，所述桨状握把构造成当将针座连接到导管适配器时邻近所述翼部定位。当迫使桨状握把与所述翼部接触时，所述桨状握把使所述翼部被提升到倾斜方位。
在另一个实施例中，本发明实施为一种IV接入装置，所述IV接入装置包括：导管适配器，导管从导管适配器向远侧延伸，所述导管适配器包括第一翼部和第二翼部，第一翼部从导管适配器的第一侧延伸，第二翼部从导管适配器的与所述第一侧相对的第二侧延伸；延长管，所述延长管在所述第二侧上连接到所述导管适配器；以及针座，针从针座向远侧延伸。所述针座构造成连接到导管适配器使得针延伸穿过导管。所述针座包括桨状握把，所述桨状握把构造成当将针座连接到导管适配器时邻近所述翼部定位。所述桨状握把使所述第一翼部以倾斜方位定位。
本发明的这些特征以及其他特征和优点可以结合到本发明的某些实施例中，并且从下面的描述和所附的权利要求中将变得显而易见，或者可以通过实施正如下文中描述的本发明而获得。本发明并不需要将在此所描述的所有有利特征和所有优点都结合到本发明的每个实施例中。

具体实施方式
图2示出了根据本发明的一个或多个实施例构造的一种封闭的IV接入装置200的一个示例。接入装置200包括：导管适配器201、针座202、延长管203和夹具207，导管201a从所述导管适配器201向远侧延伸，针202a从所述针座202向远侧延伸，所述延长管203流体连接到导管适配器201的管腔，所述夹具207用于限制流体流过延长管203。鲁尔适配器204或者其他类型的适配器可以连接到延长管203的端部。还有，鲁尔接入装置205(诸如包括隔膜的鲁尔接入装置)可连接到鲁尔适配器204。
导管适配器201可以包括由翼部201b和201c形成的稳定平台，所述翼部从导管适配器201的相对两侧向外延伸。如图2中所示，接入装置200构造成右手使用，因为延长管203连接到导管适配器201的左侧使得翼部201b完全露出。这可以便于用右手的拇指握住翼部201b。正如所示出的，延长管203可以与翼部201c基本平行地延伸。
针座202包括桨状握把202b，桨状握把从针座202的右侧向外延伸并且具有与翼部201b的形状大致对应的形状。因此，桨状握把202b可直接定位在翼部201b下面，使得在导管201a插入过程中可以将翼部201b和桨状握把202b夹在临床医生的拇指与食指之间。可替代性地，桨状握把202b可构造成被定位在翼部201b上方或附近。通过以这种方式构造桨状握把202b，临床医生可以通过将食指相对于拇指简单地向后滑动从而使桨状握把202b向后远离翼部201b滑动而容易地将针座202从导管适配器201抽出。
在一些实施例中，针座202还可以包括连接到针座202近端部的闪回室210。闪回室210可以包括塞子210a，塞子允许空气通过针座202中的近端开口溢出而防止血液溢出。还有，针202a的近端部可以延伸到闪回室210中并且可以包括允许血液从针202a流出并流入闪回室210中的开口。
根据本发明的实施例，如图3A和3B所示，桨状握把202b可以关于导管适配器201的平坦取向倾斜。图3A示出了没有连接到针座202时的导管适配器201。如所示出的，翼部201b和201c构造成平坦放置(例如在同一平面内)以在病人皮肤上形成稳定平台。延长管203也显示为与翼部201c基本平行地延伸。事实上，在接入装置200中，延长管203与导管适配器201之间的接合部形成到翼部201c中。
相对照地，图3B示出了当针座202连接到导管适配器201时翼部201b的方位。桨状握把202b可以相对于翼部201b的平坦取向以一个角度取向，当将握把202b位于翼部201b下面并与翼部201b接触时，握把202b将翼部201b提升到图3B中绘出的倾斜方位上。重要地，在翼部201b处于该倾斜方位的情况下，翼部201c保持在其平坦方位上。在翼部201b和握把202b下方形成的空间300允许临床医生将他或她的手指定位在桨状握把202b之下，同时仍然将导管适配器201保持在其平坦取向上。
更特别地，在导管201a插入过程中，临床医生可以将他或她的拇指放在翼部201b的顶部上并且将他或她的一个或多个手指放在桨状握把202b下面，同时仍然保持导管适配器201相对于病人皮肤成低角度，而不必转动导管适配器来使得翼部201c和延长管203朝向病人皮肤延伸。这样，倾斜桨状握把202b可以方便导管201a以低角度平滑插入。
在将导管适当地放入病人静脉中之后，可以从导管适配器201抽出针座202。抽出针座202将同样使桨状握把202b抽出，从而桨状握把不再以倾斜取向支撑翼部201b。结果，翼部201b可以回到其平坦方位以便于将导管适配器201抵靠病人皮肤紧固。因此，接入装置200的设计便于以低角度插入导管201a同时仍然允许导管适配器201舒适地紧固到病人皮肤。
图3A和3B绘出了一个实施例，其中，翼部201b是由柔性材料构成，从而允许其以倾斜取向定位。在一些实施例中，本发明的柔性材料的硬度从大约30邵氏A到大约90邵氏D。在一些实施例中，柔性材料的计示硬度从大约50邵氏A到大约90邵氏D。在一些实施例中，翼部201c可以由与翼部201b相同或相似的柔性材料构成。在其他实施例中，翼部201b(而且可能的话，翼部201c)可以经由铰接连接件连接到导管适配器201，所述铰接连接件允许翼部在平坦方位与倾斜方位之间枢转。当翼部201b和/或翼部201c由刚性或半刚性材料构成时铰接连接件可能是优选的。在一些情况下，翼部的柔性可以通过在翼部内形成薄的部分来形成。例如，翼部的沿着导管适配器的长度延伸的部分可以比翼部的其他部分薄从而允许翼部沿着较薄的部分弯曲。
正如上面指出的，图2、3A和3B绘出了为右手插入而设计的接入装置。通过将绘出的设计倒转，就形成了为左手插入构造的接入装置。还有，虽然本发明是参照包括延长管(例如封闭的或整合的装置)的接入装置进行描述的，但是倾斜桨状握把可以与具有由至少一个翼部构成的稳定平台的任何类型的导管适配器一起使用，所述至少一个翼部包括不包含延长管的翼部。
在一些实施例中，针座可以构造成包括两个桨状握把，用于将两个翼部都以倾斜方位定位。图4A-4E和5A-5B示出了这种两桨状握把构造的示例。
在图4A中，绘出了类似于接入装置200的接入装置400。接入装置400包括：具有导管401a的导管适配器401、紧固针402a的针座402以及从导管适配器401延伸的延长管403。导管适配器401包括从导管适配器401的相对两侧延伸的两个翼部401b和401c。两个翼部401b和401c都是柔性的以允许它们以倾斜方位定位。针座402包括两个桨状握把402b和402c，所述两个桨状握把构造成当针座402连接到导管适配器401时分别定位在翼部401b和401c下方。
正如在图4B中最佳示出的，桨状握把402b和402c以一角度取向以使得将翼部401b和401c提升到相应的倾斜方位。通过使两个翼部401b和401c都以一角度取向，可以更容易地以低角度插入导管401a。例如，如图4C中所示，如果惯用右手的用户要握住桨状握把402b和翼部401b，则该用户可沿逆时针方向稍微转动导管适配器401而不会使翼部401c朝向病人皮肤延伸。换言之，通过除了翼部401b之外，使翼部401c倾斜，在翼部401b和桨状握把402b下方可以形成更大空间以容纳用户的手指而不必要增大插入角度，同时仍然将翼部401c相对于病人皮肤保持在基本平行的方位上。类似地，如图4D中所示，在插入过程中惯用左手的用户可以握住翼部401c和桨状握把402c并且沿顺时针方向转动导管适配器401而不会使翼部401b延伸到病人皮肤中。
在已经将导管401a插入病人脉管系统中之后，可以将针座400从导管适配器401抽出，如图4E中所示。在针座400抽出的情况下，翼部401b和401c可以回到它们平坦方位上(例如在同一平面内的方位)并紧固到病人(例如经由带)。
图5A和5B示出了与接入装置400基本类似的接入装置500。接入装置500包括：具有导管501a和翼部501b和501c的导管适配器501、具有桨状握把502b和502c的针座502、以及延长管503。桨状握把502b和502c可以以与桨状握把402b和402c类似的方式起作用。然而，正如在图5中最佳示出的，桨状握把502b和502c以与翼部501b和501c类似的方式成形。相对照地，正如图4A和4B中最佳示出的，桨状握把402b和402c比翼部401b和401c短，向外延伸的距离仅大约是翼部401b和401c延伸距离的一半。
要注意的是，尽管针座400和针座500的构造不同于针座200的构造，但是针座200也可以构造成包括类似于桨状握把202b并与桨状握把202b相对的第二桨状握把。在这些情况下，针座200可以如上所述地发挥作用以将翼部201b和201c以倾斜方位定位。
在一些实施例中，即使导管适配器可以没有相应的翼部，针座也可以包括桨状握把。图6A和6B示出了以这种方式构造的接入装置600。在图6A中，针座602显示为连接到导管适配器601，而在图6B中显示为针座602与导管适配器601脱开连接。
导管适配器601包括导管601a和从导管适配器的右侧向外延伸的单翼部601b。用于将延长管603连接到导管适配器601的接合部形成在翼部601b内。虽然导管适配器601仅包括单个翼部601b，但针602a从其中延伸的针座602包括桨状握把602b和602c，所述桨状握把602b和602c构造成当针座602连接到导管适配器601时位于导管适配器601的两侧上。桨状握把602b与翼部601b的形状大致对应并且倾斜成使得其将翼部601b提升到倾斜方位。桨状握把602c可以以平坦方位构造或者以倾斜方位构造(例如与桨状握把402c和502c一样)。通过包括桨状握把602c，临床医生可以选择将导管适配器601定位在图6B中示出的方位上或者使得导管适配器601相对于针座602转动从而使翼部601b邻近翼部602c。以这种方式转动导管适配器601会使临床医生在导管601a插入过程中在左侧上握住接入装置600(与当如图6A中那样定位导管适配器601时在右侧上握住接入装置相反)。
图7A和7B示出了一种接入装置700，其包括与延长管在同一侧上的单个桨状握把和单个翼部。接入装置700包括导管适配器701，导管701a从导管适配器701向远侧延伸。导管适配器701还包括翼部701b和在与翼部701b相同侧上从导管适配器701延伸的延长管703。接入装置700还包括针座702和桨状握把702b，针702a从针座702向远侧延伸，桨状握把702b以一角度取向以使得当桨状握把702b邻近翼部701b定位(例如翼部701b之下)时翼部701b也可以以一角度取向。因此，除了针座702不包括类似于翼部602c的第二翼部之外，接入装置700与接入装置600类似。虽然没有绘出，但是可能的是接入装置700可以构造成使得延长管703在与翼部701b的相对侧上连接到导管适配器701。
总之，本发明总体上涉及接入装置，该接入装置包括针座，所述针座具有一个或多个倾斜桨状握把，用于将导管适配器的稳定平台的一个或多个翼部以倾斜方位定位。通过将翼部以倾斜方位定位，方便以低角度插入导管。
本发明的各个实施例还包括安全机构，所述安全机构构造成随着针座从导管适配器移除和分离而紧固导引针的锐利的远侧尖端。安全机构可以包括本领域中已知的兼容装置。在一些情况下，安全机构构造成与针结构相互作用，所述针结构诸如是插管上的环箍、槽口、卷边或隆起。形成于插管上的卷边或隆起形成了用于触发安全机构的微小向外圆形结构。在一些情形中，该安全机构包括臂或杆，该臂或杆被致动以将针尖端俘获在该安全机构内并且在安全处理之前防止该尖端露出。
所述安全机构连接到针的本体并且能够沿着针的长度滑动。在一些情形中，在插管术之前安全机构的初始或组装位置位于导管适配器的基部或近端部附近。对于一些构造，安全机构的组装位置在针座的近端部与导管适配器的近端部或稳定平台之间，其中安全机构不覆盖导管适配器或稳定平台。在一些情形中，安全机构的一部分位于导管适配器内，与位于导管适配器外部(诸如在针座内)的安全机构相平衡。在一些实施例中，导管适配器或者稳定平台的一部分从近端延伸以提供容纳安全机构的至少一部分的腔体。在一些情形中，在插管术之前，整个安全机构容纳在导管适配器或稳定平台的腔体内。
在一些实施例中，安全机构的组装位置使导管适配器的近端部位于安全机构的远端部与针座的桨状握把的远端部之间。在一些情形中，安全机构的组装位置使导管适配器的近端部位于安全机构的远端部与针座的桨状握把的近端部之间。在一些情形中，安全机构的一部分覆盖针座的一部分。在一些实施例中，导管适配器和桨状握把中至少一个的至少某一部分覆盖安全机构的至少某一部分。在一些实施例中，导管适配器或桨状握把的各部分都不覆盖安全机构的任何部分。
在一些实施例中，在安全机构与接入装置的至少一个其他元件之间设有可作废机械连接件。在一些实施例中，安全机构的远端部选择性地连接到导管适配器的近端部。在一个实施例中，安全机构在内部互锁到导管适配器的近端部。在一个实施例中，安全机构在外部互锁到导管适配器的近端部。在一些实施例中，安全机构的远端部选择性地连接到稳定平台的近端部。在一些实施例中，安全机构的表面选择性地连接到导管适配器、血液控制阀、延长管和稳定平台中的至少一个的至少一个表面。在一些情形中，所述机械连接件在针尖端紧固在安全机构内之后作废。
本发明可以以其他具体形式体现而不会偏离其如这里宽泛描述并且在下文中要求保护的结构、方法或其他必要特征。所述实施例旨在被认为在所有方面中仅是说明性的而并不是限定性的。因此，本发明的范围由所附的权利要求限定，而不是由前述描述限定。在这些权利要求的等价含义和范围内的所有变化包括在它们的范围内。
