技术领域
本公开大体涉及气态或液态流体传输领域,且更具体地涉及一种用于在一个或更多个管段与阴性闩之间产生可释放的流体密封连接的连接器。
背景技术
管段通常连接在一起,以便为气体和/或液体提供从一个部件至另一个部件的流体流。因此,经常期望将管段彼此连接或将管段从彼此断开。例如,当使用自动血压监视器获取患者的血压时,将来自血压袖带(其大体上绕患者的手臂缠绕)的管连接至与血压监视器相连的管。为了将袖带从血压监视器断开,理想的是仅将连接至袖带的管段从连接至血压监视器的管脱离。类似地,当提供静脉内的流体时,经常需要在不将静脉内的针或内支架从患者移除的情况下用满的流体袋替换空的流体袋。为了在第一流体袋和第二流体袋之间切换,理想的是仅将与流体袋相连的管段脱离至与静脉内地放置在患者中的针或内支架相连的管段,然后能够容易地将该于静脉内地放置在患者中的针或内支架相连的管段连接至与新的流体袋相连的管段。
由于由连接的管和部件的重量引起的侧载荷以及由患者或医护人员引起的不经意的管拉动,现有的管连接器在患者仍经由已连接的管接受治疗时易于泄露和不必要地断开。
此外,某些医疗设备需要使用多个管,用于在患者和设备之间供应流体。例如某种型号的血压监视器,诸如由通用电气General Electric制造的Dinamap Procare系列采用双管,用于将血压袖带连接至监视器。由此,包括用于在管段之间引导气流的多个空气通道的连接器是理想的,以避免在将患者连接至监视器或脱离连接器时必须单独地连接或断开多个连接器。
从前述内容,能够意识到存在对改进的卡口连接器的需要,所述卡口连接器可以连接一个或更多个管段以产生气态和/或液态流体密封部,所述密封部与阴性接收连接器协作以在阳性卡口连接器在轴向张力或侧载力的作用下放置时产生更弹性的连接并且保持不透流体密封。
在该说明书的背景技术部分所包括的信息,包括在本文中引用的任何参考文献以及其描述或论述,仅为了技术参考的目的而被包括并且不应该被认为是界定本发明的范围的主题。
发明内容
改进的阴性管连接器在本文中公开,所述改进的阴性管连接器减小用于与阳性连接器联接所需的插入力。此外,该阴性管连接器增加一旦阳性连接器被固定在阴性管连接器内后将阳性连接器拔出所需的力的量,以防止阳性连接器从阴性连接器意外断开。
通常,与阴性管连接器的按钮联接的锁定构件可以采用各种形式以帮助确保联接或断开阳性连接器的相对低的插入力和相对高的拔出力。具体地,锁定构件可以包括轮廓导入部分以帮助减少将阳性连接器插入到阴性连接器中的力的量,同时增加在阳性连接器与阴性连接器联接之后将阳性连接器拔出的力的量。
在一个实施例中,提供一种用于连接管段的阴性接收连接器。阴性接收连接器包括壳体,该壳体具有顶壳体部分和联接至所述顶壳体部分的底壳体部分。阴性接收连接器还包括按钮,所述按钮以可移动方式联接在壳体内。锁定板与按钮一体或与按钮联接,并且被构造成与按钮一起移动。锁定板具有轮廓导入部分,该轮廓导入部分具有位于轮廓导入部分的近端侧处的接界表面,用于与阳性连接器接界。接界表面沿着形成在锁定板内的孔口的周向边缘的至少一部分延伸,并且沿着周向边缘的该部分渐缩。此外,轮廓导入部分包括位于具有高弧线的导入部分的远端侧处的锁定表面,用于将阳性连接器固定在阴性接收连接器的壳体内。大致平坦表面位于接界表面和锁定表面之间。
在另一实施例中,提供一种用于传输流体的阴性接收连接器。该阴性接收连接器包括壳体,该壳体限定用于流体流的至少一个内腔。壳体包括顶壳体部分、联接至顶壳体部分的底壳体部分和以可移动方式联接在壳体内的按钮。此外,阴性接收连接器锁定构件,该锁定构件联接至按钮并且被构造成在力被施加至按钮或锁定构件的表面时与按钮一起移位。锁定板具有轮廓导入部分。轮廓导入部分包括:位于轮廓导入部分的近端侧处的弯曲表面,用于与阳性连接器接界;位于轮廓导入部分的远端侧处的锁定表面,用于将阳性连接器固定在阴性接收连接器的壳体内。大致平坦表面位于弯曲表面和锁定表面之间,并且弯曲表面从锁定构件的近端面延伸至大致平坦表面。
提供该发明内容部分以便以简化形式介绍将会在下面在具体实施方式部分中进一步描述的构思选集。该发明内容部分不是旨在用于确定所要求保护的主题的主要特征或本质特征,也不是旨在用于限制所要求保护的主题的范围。本发明的优点、效用、细节和特征的更广泛的陈述在以下本发明的各个实施例的书面描述中提供、在附图中图示、并且在所附权利要求中限定。

具体实施方式
阴性接收连接器的实施例与阳性卡口连接器一起可以用于以可释放方式连接管段。在一个实施例中,阴性接收连接器包括具有轮廓导入部分的闩板,所述轮廓导入部分沿着在闩板中的孔口的横向侧向上延伸。轮廓导入部分为闩板提供延伸的闩锁表面以将阳性卡口连接器固定。当阳性卡口连接器插入到阴性接收连接器中时,阳性卡口连接器的远端接界轮廓导入部分,向下偏压闩板,并且降低接收孔口,阳性卡口连接器可以穿过所述接收孔口。阳性卡口连接器包括环形槽道,在阳性卡口连接器充分插入到阴性接收连接器中后,所述环形槽道由轮廓导入部分接合。
在本文中使用的定向“近端”和“远端”已经被任意地选择,并且不旨在限制本公开,而是将遵循刚才关于阴性接收连接器206和阳性双卡口连接器102的端部描述的约定。
在替代实施例中,阴性接收连接器可以包括锁定板,该锁定板具有作为在锁定板中的孔口的弯曲底表面的轮廓导入部分。当阳性卡口连接器插入到阴性连接器中时,阳性卡口连接器接界轮廓导入部分,向下偏压锁定板并且降低接收孔口,阳性卡口连接器可以穿过该接收孔口。在阳性卡口连接器充分地插入到阴性接收连接器中之后,阳性卡口连接器的环形槽道由轮廓导入部分的远端表面接合。
在一些实施例中,轮廓导入部分可以被实现为多个平行的内腔构造。例如,在一些实施例中,轮廓导入部分可以被实现为双内腔构造(例如阴性连接器具有两个平行内腔,液体可以穿过该两个平行内腔并且阳性连接器可以插入到该两个平行内腔中)。此外,在一些实施例中,轮廓导入部分可以具有接合阳性卡口连接器的环形槽道的一个或更多个斜切表面。在一些实施例中,锁定板的远端边缘可以是平坦的以与环形槽道的平坦表面接界。
图1中图示了一个示例性阴性接收连接器100。阴性接收连接器100包括壳体102,该壳体102具有顶部分104和底部分106。按钮108以可移动方式联接至壳体102,并且能够从外部接触以允许将阳性连接器从锁定构件脱离,如在下文中更详细地论述的。壳体102和按钮108可以由合适的材料经由合适的过程制成。在一些实施例中,壳体102和按钮108可以由塑料材料经由模制过程、诸如注射成型过程制成。在其他实施例中,阴性接收连接器100的一个或更多个部分可以经由铣削过程、诸如计算机数字控制(CNC)铣削过程而制成。可以以合适的方式将顶部分104和底部分106固定在一起,诸如实施卡扣配合,所述卡扣配合与顶部分和底部分一体地形成。在其他实施例中,可以以其他方式,例如,经由粘合剂或超声波焊接将顶部分和底部分固定在一起。
壳体102包括接收孔口110,阳性卡口连接器可以插入穿过该接收孔口110。孔口110位于阴性接收连接器100的近端处并且可以由壳体102的上部分104和/或下部分106限定。孔口110构成延伸穿过阴性接收连接器100的内腔112的近端。内腔112继续穿过位于阴性接收连接器100的远端处的带倒钩的管连接器114。带倒钩的管连接器114被构造用于附接塑料管。
图2示出了阴性接收连接器100,其中壳体102的顶部分104被移除,以示出在壳体102内侧的额外细节。如所图示,按钮108包括锁定板120。在一些实施例中,锁定板120可以与按钮108一体地形成,然而在其他实施例中,锁定板120和按钮108可以分开地形成并且随后联接在一起。此外,在其他实施例中,可以使用按钮之外的结构,例如滑动件、开关、操纵杆、或其他结构以操作锁定板120。锁定板120从按钮108向下延伸并且被构造成与按钮108一起移动。密封构件122诸如橡胶O型环可以直接位于锁定构件120的后方。密封构件122被密封构件保持件124固定在锁定板120的后方的位置。密封构件保持件124可以是密封构件122插入和保持在其中的合适保持结构。在一些实施例中,密封构件保持件124可以与壳体102的底部分106一体地形成。在其他实施例中,密封构件保持件124可以与壳体102的底部分106分开形成并且随后联接至该底部分。密封构件122可以被固定在位于密封构件保持件124后方的槽道内。
锁定板120包括轮廓导入部分128。图3图示了独立于壳体102的底部分106的按钮108,使得可以更容易地观看和描述轮廓导入部分128。通常,轮廓导入部分128沿着锁定板120的孔口142的边缘140向上延伸。轮廓导入部分128功能用作改进的锁定结构。即,因为其沿着孔口142的边缘向上延伸,所以轮廓导入部分128提供用于在阳性卡口连接器中锁定的附加结构。
如所图示,按钮108包括作为一体式部件的锁定构件120。此外,按钮108包括弯曲支腿130,该弯曲支腿130可以与壳体102的底部分106接界并且功能用作弹簧以将按钮108向上地保持在壳体102内。即,支腿130具有向上地保持按钮108的垂直延伸位置。当按钮被下压时,支腿130可以弯曲,并且当压力释放时,支腿可以返回至完全伸展,因此提供弹簧功能。在其他实施例中,可以采用弹簧之外的其他类型的机械动作以在力被移除时将按钮升回至其静止位置。
图4是在图3中示出的按钮108的孔口142的放大图。如可以看见的,轮廓导入部分128具有斜坡式形状。特别地,随着轮廓导入部分128沿着孔口142的边缘140向上前进,轮廓导入部分128的近端表面132朝锁定板120的远端边缘134渐缩。该斜坡被设置成使得例如,在阳性卡口连接器插入到阴性接收连接器100中期间,随着阳性卡口连接器被抵着轮廓导入部分128下压,锁定板120被推压向下。斜坡的斜度的角度范围取决于凹槽距离阳性连接器的尖端的前部的距离或阳性连接器需要行进以将轮廓导入部分锁定在阳性连接器上的凹槽中的距离。在一些实施例中,斜坡可以在44°和46°之间倾斜。
图5示出了孔口142,孔口142包括具有重叠周边的两个大体圆形区域。第一区域150由在孔口142的下部分中的第一周边152限定。轮廓导入部分128和基部导入部分154限定第一区域150的周边152。第二区域156由第二周边158限定。第二周边158的一部分可以由轮廓导入部分128的顶边缘限定。这样,轮廓导入部分128的顶边缘可以具有弯曲形状。
第二周边158和第一周边152重叠。第二周边158比第一周边152大,并且,因此,第二区域156比第一区域150大。第二区域158足够大以允许阳性卡口的通过,而第一区域152用作锁定孔口以接合并且保持阳性卡口连接器。
图6图示了进入壳体102的孔口的阳性卡口连接器160。在一些实施例中,阳性卡口连接器可以包括形状为截头圆锥的近端部分162,该截头圆锥可以用于联接塑料管。连接器的远端部分164可以是具有大致平坦表面的大体圆柱形,该大致平坦表面可以在阳性卡口完全插入到阴性接收连接器100中时用作密封表面。在其他实施例中,阳性连接器的远端部分164可以具有其他形状。例如,在一个实施例中,远端部分164可以具有截头锥形状。此外,在一些实施例中,阳性连接器160的最前边缘166可以具有斜切边缘。在一些实施例中,最前边缘166可以具有弯曲形状。
阳性连接器还具有位于近端162和远端164之间的环形槽道168。环形槽道168可以具有可以用于接合锁定板120的平坦或倾斜的边缘。例如,在一些实施例中,边缘可以倾斜以相对于由阳性连接器限定的内腔的轴线形成45度角度。在其他实施例中,倾斜边缘可以垂直于轴线、圆化、或可替代地可以限定在0和90度之间的任何角度。
在一些实施例中,第一区域150的近端表面170可以具有与阳性卡口连接器160的最前边缘166对应的形状。例如,近端表面170可以斜切或弯曲。阳性卡口连接器160的最前边缘166的形状、第一区域150的近端表面170、和/或轮廓导入部分128可以辅助锁定板120相对于阳性卡口连接器160的移动。
在阳性卡口连接器160进入到壳体102中时,阳性卡口连接器160接触孔口142的近端表面。在施加压力以将阳性卡口连接器160插入穿过孔口142时,如箭头169(图6、7和8)所指示的,锁定板120被迫使向下,如箭头171(图7和8)所述指示。特别地,因为斜坡式轮廓导入部分128,在通过将阳性卡口连接器160推入到孔口中而向锁定板120施加压力时,锁定板120被迫使向下。锁定板120继续向下直至阳性卡口连接器160能够穿过第二孔口158(图8)。阳性卡口连接器160穿过第二孔口158直至阳性卡口连接器160的槽道与轮廓导入部分128对准。当槽道168与轮廓导入部分128对准时,锁定板120被支腿130向上推回并且轮廓导入部分128接合槽道168以将阳性卡口连接器160固定在阴性接收连接器100内(参见图9)。
轮廓导入部分128的远端表面的形状可以使得一旦阳性卡口连接器160被安装就将阳性卡口连接器160保持到位。例如,在一些实施例中,轮廓导入部分的远端表面可以是平坦的。在其他实施例中,该远端表面可以斜切。斜切表面可以便于锁定板120接合阳性卡口连接器的槽道168。在一些实施例中,近端表面和远端表面可以斜切。在另一实施例中,轮廓导入部分128的远端或近端表面中的一个是斜切的并且另一表面是平坦的。
在一些实施例中,槽道168的表面的形状可以与轮廓导入部分128的表面对应。例如,在一个实施例中,槽道168的远端表面可以是斜切的并且轮廓导入部分128的远端表面可以是斜切的。在一些实施例中,槽道168的远端和近端表面都可以是斜切的。在一些实施例中,槽道168的近端和远端表面都可以是平坦的。在其他实施例中,近端或远端表面中的一个可以是斜切的并且另一表面可以是平坦的。在每一种情况中,阳性卡口连接器160的槽道的两个表面或两个表面中的一个表面的形状对应轮廓导入部分128的相应表面的形状。即,如果轮廓导入部分128的远端表面是平坦的,则槽道168的远端表面相应地是平坦的。此外,轮廓导入部分128的厚度与阳性卡口连接器160的槽道的宽度近似相同。
当锁定板120将阳性卡口连接器160锁定到位时,阳性卡口连接器160的远端部分可以与密封构件122接触以在密封构件122和阳性卡口连接器160的远端部分164的表面之间形成密封部。
按钮108可以被向下压下以从阴性接收连接器100释放阳性卡口连接器160。特别地,当向下压下按钮108时,锁定板120向下移动直至阳性卡口160可以完全离开轮廓导入部分128并且可以穿过第二区域156。
如在上文中所提及的,阴性接收连接器100可以实现为多内腔构造。例如,阴性接收连接器100可以包括两个、三个、或更多个内腔。对于每一个内腔均设置有锁定板。在一些实施例中,可以将一个或更多个锁定板联接在一起。此外,在一些实施例中,一个或更多个锁定板可以与按钮108一体地形成。在一些实施例中,一个或更多个锁定板可以独立形成并且随后联接至按钮108。此外,在一些实施例中,一个或更多个锁定板的形状可以包括一个或更多个不同于其他锁定板的特征。例如,在一个实施例中,与第一内腔相关的第一锁定板可以具有斜切的近端表面,然而与第二内腔相关的第二锁定板可以具有弯曲的近端表面。在另一示例中,第一锁定板的远端表面可以具有斜切的表面,然而第二锁定板的远端表面可以具有平坦的表面。
图10图示了根据示例性实施例的双内腔阴性接收连接器200。在一个实施例中,双阴性接收连接器200可以被设计用于连接来自血压监视器的管和阳性连接器,该阳性连接器附接至来自血压袖带的管,所述血压袖带可以绕患者的手臂紧固。双内腔阴性接收连接器200允许在连接器内的两个空气通道。如在上文中所论述的单内腔,双内腔阴性接收连接器200包括壳体202,该壳体202可以包括上部分204、下部分206以及按钮208。
图11图示了具有锁定板210和支腿212的按钮208。支腿212用作弹簧构件以在壳体202内将按钮208保持在升起位置。此外,支腿212提供保持力以在阳性连接器230与阴性接收连接器联接在一起时将阳性连接器230固定在阴性接收连接器中。即,支腿212在锁定板210接合阳性连接器230的同时将锁定板210保持到位。
锁定板210包括两个孔口220,双内腔阴性接收连接器200的每一个内腔对应一个孔口220。在一些实施例中,孔口220可以是完全相同的。即,孔口220可以具有相同的或类似的尺寸和形状。然而在其他实施例中,孔口220可以具有不同的尺寸和形状。此外,在一些实施例中,内腔可以用于传输相同的流体,然而在其他实施例中,一个内腔可以传输与另一内腔不同的流体。
锁定板210的孔口220被构造成便于将阳性卡口连接器230插入到阴性接收连接器200中,同时防止阳性卡口连接器230从该孔口220移除。这样,孔口220包括弯曲的轮廓导入部分240。轮廓导入部分240构成孔口220的下边缘242。轮廓导入部分240在图11和图12中示出并且大体可以具有提供弯曲外形以便于将阳性卡口连接器230插入或固定在阴性接收连接器200内的区域。例如,在一个实施例中,中心区域250可以包括弯曲部分252,该弯曲部分252从锁定板210的近端边缘朝在孔口220的内部上的大致平坦表面254延伸。大致平坦表面具有由圆256(图12)的半径限定的外形,该圆256的半径与阳性卡口连接器230的外表面的半径对应。所述外形的半径可以更大或更小,只要其能够接受阳性卡口连接器230的槽道并且与阳性卡口连接器230的槽道接界。大致平坦表面254延伸至左区域260和右区域262。在左区域260和右区域262中,大致平坦表面254朝锁定板210的远端边缘264渐缩。在一个示例性实施例中,导入部分240的角度是45度,从而导致大体平坦锁定表面254的0.20″的半径。如在图11中看到的,锁定表面254可以形成具有微小(例如0.097″)半径。锁定边缘254朝孔口220的边缘过渡至在左区域260和右区域262中的球根状、辐射式边缘。左区域260和右区域262的形状是使阳性连接器轻易插入的主要因素,由于其骑跨在球根状表面上,从而将按钮推压至“下”位置。
弯曲部分252也延伸到左区域260和右区域262中。例如,在左区域260中,弯曲部分可以具有凸形外形。该凸形外形可以从锁定板210的近端边缘266朝锁定板210的远端边缘264延伸。因为大致平坦表面254在左区域260中渐缩,所以凸形外形随着其从中心区域250前进穿过左区域260而扩展。弯曲部分的顶点延伸到孔口的边缘272中,从而形成弯曲横档。右区域262大体是左区域260的镜像并且同样地具有类似特征。
参照图12,可以看见大致平坦表面254的轮廓。如在上文中所论述的,中心区域250的大致平坦表面254可以由圆256的周边限定,所述圆256的周边与阳性卡口连接器230的槽道的周边相关。然而在不同的实施例中,左区域260和右区域262的大致平坦表面254可以具有不同的轮廓。例如,在一个实施例中,大致平坦表面254的轮廓可以由在左区域260和右区域262中的大致直线限定。在一些实施例中,所述轮廓可以具有随着其接近边缘272而减少的斜率,从而限定凸形轮廓。在其他实施例中,轮廓可以稍微凹入,但是凹入的程度少于中心区域的轮廓。
轮廓导入部分240在插入期间为阳性卡口连接器230提供初始接触表面。图3图示了进入阴性接收连接器200的阳性卡口连接器。在图13中,顶壳体构件被移除以示出在壳体内的细节。图14是示出了接触中心区域250的轮廓导入部分240的阳性卡口连接器230的横截面图。阳性卡口连接器230与轮廓导入部分240的接触迫使锁定板210向下直至阳性卡口连接器230的密封表面能够穿过孔口220,如图15所示。阳性卡口连接器230可以进一步插入到孔口220中直至阳性卡口连接器230的槽道与中心区域250的大致平坦表面254接合,以将阳性连接器230固定在阴性连接器200内。当阳性卡口连接器230被固定在阴性接收连接器200内时,密封构件诸如橡胶O型环,可以接触阳性卡口连接器230的密封表面以密封内腔。
如在图17中所图示,大致平坦表面254可以垂直邻接轮廓导入部分240的平坦的远端表面238。即,在一个实施例中,轮廓导入部分240的远端表面可以是平坦的。在一些实施例中,轮廓导入部分240的远端表面和锁定板210的远端表面可以是相同的表面。在其他实施例中,它们可以构成不同的表面。槽道的相应接合表面也可以是平坦的以帮助将阳性卡口连接器230固定在阴性接收连接器200内。在其他实施例中,锁定板210的远端表面280可以采用其他形式。例如,在一个实施例中,所述远端表面280可以是斜切的。
图17是从阳性卡口连接器230和按钮208的远端透视角度得到的部分横截面图,其中阳性卡口连接器被固定在锁定板210内。如能够看见的,阳性卡口连接器230被固定在孔口220的下部分内,然而孔口的上部分是未被占用的。此外,锁定板210的轮廓导入部分240、大致平坦表面254和远端表面280可以每一个均接触阳性卡口连接器230的槽道以固定阳性卡口连接器。
应意识到,在其他实施例中,轮廓导入部分240可以采用其他形式。图18-20图示了示例性轮廓导入部分的替代实施例。特别地,图18图示了具有与在图11和图12中所示的实施例相同的总体特征的实施例,但是在左区域和右区域中的轮廓导入部分282进一步向上延伸到孔口220的边缘272。图18具有在阳性轴被模制在公差范围的大端上的情况下的较小的“球根状”半径。较小的半径将使得阳性轴能够更加轻易地在按钮闩上滑移并且迫使按钮闩向下。因此,当与在图11和图12中示出的实施例相比时,在左区域和右区域中的轮廓导入部分282可以具有更平缓的外形。
图19图示了具有轮廓导入部分290的实施例,该轮廓导入部分290具有连续的轮廓,该连续的轮廓具有在狭小和短的平坦接合表面292上的非常小的侧高弧线。即,平坦接合表面292的整体可以具有由圆的周边限定的轮廓,所述圆的周边与阳性卡口连接器230的槽道的周边对应。随着大致平坦表面292接近边缘272,大致平坦表面292从锁定板210的近端边缘294至远端边缘296逐渐缩小。
图20图示了与在图11、12和18中图示的实施例类似的实施例,该实施例具有轮廓导入部分298,该轮廓导入部分298与图18和图19的形式相比具有更高的边缘高弧线300,但是与在图3中的实施例相比具有更低的高弧线。图20具有在阳性轴被模制在公差范围的小侧上的情况下的较大的球根状半径。较大的球根状半径将使得与被模制成标称尺寸的轴相比,导入部分298与阳性轴之间的交界部能够发生在大约相同的阳性插入深度。平坦表面302比在图19的实施例中的平坦表面宽并且延伸到边缘272中以形成横跨孔口的底部的横档。在图20中,边缘272是厚、平坦并且直的。
轮廓导入部分被设计成维持阳性连接器的相对低的插入力,同时还维持锁定板的坚固的远端边缘,使得其在阳性连接器完全插入时将阳性连接器锁定/保持至阴性接收连接器。已经建造了在上文中描述的各种实施例的原型并且执行了实验以确认向下致动锁定板以允许将阳性连接器插入的阳性连接器插入力是相对低的。此外,执行了实验以确认导致阳性连接器在完全插入并且锁定时从阴性接收连接器脱离的轴向拉动力是相对高的。
对于本领域技术人员显而易见的是:给定上述描述,可以做出变型和替代实施例。该变型和替代实施例因此被认为是在本发明的范围内。例如,轮廓导入部分可以实现为具有弯曲部分以形成轮廓、轮廓导入部分。
如在本文中使用的,内腔不仅指代其的定义,也指代开口、孔口、或其它出入口。在本文中提及的流体可以是气态的、液态的、或能够流动穿过管的其他状态的(即颗粒状的)材料。此外,尽管在上文中连接器结构在连接在一起时大体描述为密封的,但是连接器结构可以是密封的或非密封的。阳性双卡口连接器和阴性接收连接器以及他们的各个管段之间的连接可以是通过不是倒钩配合的方法,例如,但不限于螺纹连接、不使用倒钩的压配、John Guest配合、金属箍、以及面板安装。
所有的方向性参照(例如上、下、向上、向下、左、右、向左、向右、顶部、底部、上方、下方、内部、外部、竖直、水平、顺时针、以及逆时针)仅用于识别的目的以辅助读者理解本发明的示例,且不特别对本发明的使用、定向或位置产生限制,除非在权利要求中明确指出。连接参考(例如附接、联接、连接以及连结)应该被广泛的理解并且可以包括在连接元件之间的中间构件以及在元件之间的相对移动。同样地,连接参考不必要推断为两个元件直接相连并且处于相对彼此固定的关系。
在本文中直接或间接陈述的方法论中,以一种可能的操作顺序描述了各种步骤和操作,但是本领域技术人员将会意识到在没有必要地脱离本发明的精神和范围的情况下,步骤和操作可以再排列、替代、或消除。意图在于:在上面描述中包含的和在附图中示出的所有内容应该认为仅是示意性的而不是限制。可以在没有脱离如在所附权利要求中限定的本发明的精神的情况下改变细节或结构。
