相关申请的交叉引用
[0001]本申请要求美国临时申请序列号61/012,825，申请日2007年12月11日的优先权，其全部内容通过引用在此并入全文。
技术领域
[0002]本公开涉及生物医学电极，尤其是，涉及一种生物医学电极连接器，用于将导线连接到布置于患者身体上的心电图(ECG)电极上。
背景技术
[0003]广泛地使用心电图(ECG)监视器以获取包含关联于心肺系统的电活动的指示信息的医学(即，生理电势)信号。为了获取医学信号，ECG电极应用在患者皮肤的各个部位。在电极布置在患者上之后，电极通过一组ECG导线连接到ECG监视器。ECG导线的远端或最靠近患者的部位可以包括连接器，其适于可操作地连接电极以从人体接收医学信号。ECG导线组的近端可操作地连接于ECG监视器并且将从人体接收到的医学信号提供给ECG监视器。
[0004]典型的ECG电极组件可以包括电导层和背面层，该组件具有患者接触侧和连接器侧。电极垫的接触侧可以包括生物相容性导电凝胶或粘合剂，以将电极附着于患者身体上以促进患者身体和电极组件之间的适当的电连接。该垫的连接侧可以与具有球根状轮廓的金属钮结合以将电极垫和ECG导线耦接。在使用中，临床医生从电极侧移除保护的覆盖物以暴露凝胶或粘合剂，将电极垫附着到患者身体上，并通过按压或“卡扣”导线连接器到球根状压触头上而将适当的ECG导线连接器附加到压触头，以实现电极和导线之间的机电连接。使用后，临床医生通过从垫上拉开或“解扣”连接器而将ECG连接器从垫上移除。
[0005]该描述的ECG导线连接器可能具有弊端。临床医生必须施加相当大的向下的力在导线连接器上以实现连接器和压触头之间的充分接合。该高连接力可能导致患者的额外的和不必要的不适或疼痛，其现存的医疗情况可能是不适或疼痛的源头。在ECG过程中通常使用的连接多个电极的需要可能增加患者的不适。
[0006]在完成ECG过程时，临床医生必须将ECG导线连接器从垫上解扣下来，其可能会进一步导致患者的不适。在一些实例中，连接器并不能轻易地从压触头上脱离，因此需要临床医生使用相当大的向上的力以取下连接器。通常，这些将ECG导线连接器从电极压触头中取下的努力反而将导致垫从患者的皮肤上突然地或痛苦地撕裂。在其它实例中，分离ECG导线的努力将导致垫从患者处部分地脱离，其可能削弱电极接收生理电势信号的能力。例如，当临床医生期望暂时地分离导线而仍然将垫保持就位以稍后在患者身上执行ECG测试的时候，这是不期望的。
[0007]在其它实例中，弹簧锁连接器可以使用不大的力来接合压触头，其可能导致从电极到导线的未达到最佳标准的信号传输，同时也导致连接器被无意脱离，例如，由于导线上轻微地拖拽。这些影响都是不期望的，因为它们可能使ECG过程失效，需要患者耗时重新测试，或者可能导致滞后的，不准确的或不可靠的测试结果。
[0008]此外，当同时努力避免上述提及的不利影响的时候，从ECG垫上摁扣和解扣导线连接器的过程在ECG临床医生方面需要相当大的手工灵敏度。一旦临床医生每天典型地重复电极连接/断开程序多次后，上述弊端可能导致临床医生的不满和疲劳。
发明内容
[0009]根据本发明的一个实施例，在此提供一种ECG导线连接器，其包括外壳和具有开启和关闭位置的拇指形凸轮杆。在开启位置，ECG电极组件的压触头可以插入到外壳提供的配合容器中，可选择地使用可忽略的或无插入力。一旦放置到位置上，拇指形凸轮杆可以移动到关闭位置，因此不需要对ECG电极垫或患者使用不期望的力，就可以充分地耦接压触头和连接器。该公开的杆可以提供制动器，以在关闭位置提供连接器的充分锁止以实现压触头和连接器之间的最佳电耦接，并且此外还提供可触知的反馈给临床医生，即完全地锁止了拇指形凸轮杆。
[0010]连接器可以包括弹簧元件，当杆不是锁止的时候使拇指形凸轮杆偏压在开启位置的方向上。该弹簧元件设置为在拇指形凸轮杆位于关闭位置的时候可操作地接合球根状压触头的狭窄的“腰”部。当拇指形凸轮杆在关闭位置的时候，弹簧元件偏置压触头以相对于连接器外壳内提供的配合的电触点元件，以电耦接压触头和接触元件，并且实现压触头和连接器外壳之间的充分机械耦接。该电触点元件可以通过任意合适的方法而可操作地连接于导线的远端，如钎焊、卷边、熔焊、或引丝结合(wire bond)。导线的近端可以以任意合适的方法而终止，如到连接器，以可操作地连接导线到ECG监视器。可以通过溢放口而从外壳在导线出口处支撑导线。
[0011]根据本发明的另一实施例，提供一种ECG导线连接器，包括外壳，以及具有外部表面和内部接合表面的按钮。当释放时(即，当没有压力应用于按钮时)，通过弹簧元件使该按钮向锁止位置偏压，以及当按下时(即，当例如，临床医生提供足够的压力应用到按钮的表面时)，按钮具有非锁止位置。在连接器外壳内提供附着的用以接收电极垫压触头的容器。当按下按钮后，其接合表面设置为允许压触头插入到容器中，可选择地使用可忽略的或不使用插入力。一旦插入压触头，则可以释放按钮，其导致弹簧元件相对于压触头偏压按钮的结合表面，接合压触头和连接器外壳内提供的配合的电触点元件，以电耦接压触头和接触元件，以及实现压触头和连接器外壳的足够的机械耦接。
[0012]在本公开的范围内设想的实施例中，按钮表面可以布置在连接器外壳的远端。弹簧元件可以是布置在按钮近端和连接器外壳内提供的相应的鞍之间的螺旋弹簧。通过按钮中央部分内提供的开口限定接合表面。
[0013]在本发明构思的另一实施例中，按钮是枢转杆，其在一端具有布置在连接器外壳的中央部位的外部表面，以及在相对端具有用以接合压触头的接合表面。弹簧元件可以是布置在杆表面端部、外壳和杆之间的板簧，使得杆表面端从外壳向外偏压。额外的或替代的，板簧可以布置在杆的夹紧端。
[0014]在各种实施例中，可以设想的，电触点元件提供接触开口以接收压触头。该开口可以具有窄端和宽端。例如，开口可以为具有一对称轴的卵形(“蛋形”)。备选的，接触开口可以为梨形，钥匙孔形，圆形或描述为具有不同半径的两个部分重叠的圆的交迭部分。可以设计开口的宽端的尺寸以接受球根状压触头，选择性地具有可忽略的干涉或无干涉。相反地，可以设计开口的窄端的尺寸以容纳压触头的狭窄的腰部。接触开口可以这样设置，使得当接合时，压触头相对于接触开口的窄端偏置和/或夹紧。
[0015]可以理解的是，此处公开的弹簧元件并不限于螺旋弹簧和/或板簧，并且可以包括任意合适的偏置力源，包括但并不限于气压弹簧、压力或真空致动设备、橡胶弹簧、磁或电磁设备、形状记忆合金电机、以及其它本领域技术人员熟知的偏置力源。额外的或备选的，弹簧元件可以与例如外壳、杆、或按钮一体形成。
[0016]本公开范围内还设想了其他实施例，如ECG导线连接器，具有多个按钮，例如，其布置在外壳的相对侧上，其中至少一个按钮可操作的与ECG垫的压触头接合和脱离。
[0017]设想的压触头接合的备选形式，其中，例如，按钮以推进/推开的方式操作。在该结构中，初始地以开启或非锁止的结构提供连接器。压触头可以随后插入到容器中，可选择可忽略的插入力或不使用插入力。一旦就位，在第一推进阶段中可以通过按下按钮以接合压触头。为了脱离压触头，在第二推开阶段中第二次按下按钮以释放按钮，并重新设置连接器回初始状态，因此准备连接器供随后使用。在压触头接合的另一种模式中，连接器包括偏置力源，例如弹簧元件，其配置为当检测到触发事件时(如压触头插入到连接器)自动地接合压触头。为了脱离压触头，提供释放控制，如按钮或杆，使得当激励所述释放控制(即，按下或移动)的时候，压触头从外壳释放和/或弹出。进一步的设计，激励释放控制重新设置连接器到初始状态，因此准备连接器供随后使用。设计脱离的其他形式，其中，例如，可以通过推、拉、扭曲或其他操作移动连接器外壳来脱离压触头。

具体实施方式
[0049]参照附图，在此详细描述本公开的ECG电极连接器和方法的实施例，其中在各个视图中相同的参考数字指示相同的或相应的元件。如附图所示和如下文说明书所描述的，当涉及到目标的相对位置的时候，习惯的，术语“近”表示装置靠近监视器的一端，而术语“远”表示装置远离监视器的一端。在下文描述中，将不详细描述公知的功能或结构以避免在不必要的细节上模糊本公开。
[0050]参照图1，2和3A，示出了具有拇指形凸轮杆110的ECG电极连接器100的实施例。连接器100包括具有腔106的外壳105、枢轴销115、以及具有枢轴孔116的拇指形凸轮杆110，其中限定的枢轴孔116的尺寸使得拇指形凸轮杆110枢轴地耦接于枢轴销115。连接器100也可以包括盖305，盖305可选择地包括可通过任意合适方法而与盖305一体形成的指示标记310，方法包括但不限制于印刷、雕刻、丝印、印花、或所述标记310整体成型于盖305上。可以采用任意合适的非导电材料构造外壳105、杆110和盖305，包括但不限制于任何热塑性和/或弹性聚合物，如聚对苯二甲酸丁二醇酯(PBT)，聚对苯二甲酸乙二酯(PET)，聚氯乙稀(PVC)，丙烯腈-丁二烯-苯乙烯聚合物(ABS)，热塑性聚氨酯(TPU)，热塑性硫化橡胶(TPV)，聚丙烯(PP)，聚乙烯(PE)，和/或纤维增强聚合物(FRP)。
[0051]具有卷基部130、固定腿131和可动腿132的V型弹簧120耦接于外壳110的腔106内。V型弹簧120的卷基部130可以是多圈、单圈或者无圈的V型顶尖。V型弹簧120通过销117保持在其基部且通过鞍125在其固定端连接到外壳105，使得可动腿132在远端方向偏置，即，朝向枢轴销115。额外的或备选的，V型弹簧120可以以任意合适的结合方式连接到鞍125或腔106，如粘合或热焊。止挡件135限制可动腿132的向外弯曲。拇指形凸轮杆110包括凸轮102，如图2所示，该凸轮102在拇指形凸轮杆120移动到关闭位置的时候与弹簧元件120的制动器140相连。制动器140和凸轮102共同作用以锁止拇指形凸轮杆110于关闭位置，并且额外的或替代的，提供可感知的反馈给临床医生。可以通过杆制动器160和在拇指形凸轮杆110上设置的相应凹陷(未示出)的接合而提供额外的锁止和可感知的反馈。当杆110位于关闭位置的时候，外壳105可以设有杆凹座180以接收杆110。外壳105上设有手指凹座165，以帮助临床医生对拇指形凸轮杆110的处理和/或操作。
[0052]连接器100进一步包括电触点元件155，其布置于腔106之上。可以采用任意合适的导电材料构造电触点元件155，包括但不限制于不锈钢或低碳钢。也可以设想采用具有导电涂层的非导电材料构造电触点元件155。电触点元件155可以以任意合适的连接方式电耦接于导线175，如卷边156，或额外地或替代地，焊接或电线粘结。导线175可选地可以被溢放口170在外壳105上支撑在其退出点处。电触点元件155提供了接触开口145，其限定为接收电触点，如ECG垫的球根状压触头。在该实施例中，接触开口145可以为不对称形的，例如，其宽端151的尺寸以接受球根状压触头、其窄端150的尺寸以容纳压触头的狭窄的腰部的卵形。现在参照图3B、3D、10A和10B，外壳105的底部表面330提供了布置于其上的孔320，其暴露接触开口145给连接器100的外部以帮助压触头插入到连接器中。
[0053]如图1所示，可以通过将杆110放置到开口位置来实现将压触头接合到连接器100中，因此凸轮102旋转远离制动器140，允许V型弹簧120的可动腿132在远端弯曲并停靠在止挡件135上。压触头随后可以被引入连接器100，例如，通过放置连接器100在压触头上，使得球根状端压触头布置到开口145内，如图10A所示。压触头插入之后，如图2所示，随后可以移动杆110到关闭位置，导致凸轮102旋转向V型弹簧120的可动腿132。凸轮102的旋转使其越过制动器140从而在近端方向压缩可动腿132，其在开口145的窄端150与压触头机械接合和电耦接，如图10B所示。相反地，通过将杆110从关闭位置移动到开启位置，所述与连接器100接合的压触头可以脱离，导致凸轮102旋转远离制动器140和放松V型弹簧120的可动腿132，其脱离压触头并允许其如易于理解的移除。在图11A和11B所示的另一实施例中，提供了ECG电极连接器1100，其中设置凸轮以导致压触头和电触点元件之间的机械接合。可以增加弹簧以帮助杆110的打开和开动。
[0054]现在参照图4，5，6A和6B，根据本发明的另一实施例提供了一种ECG导线连接器400，其包括提供腔406的外壳405，以及具有外部表面411和内部接合表面432的按钮410。连接器400也可以包括盖605，盖605可选择地包括如此前所述的指示标记610。如前所述的，可以采用任意合适的非导电材料构造外壳405、按钮410和盖605。
[0055]按钮410可滑动地布置在外壳405内并通过螺旋弹簧420而在远端方向上被偏压，螺旋弹簧420通过按钮410提供的鞍426而保持在其远(按钮)端，以及通过外壳405提供的鞍425而保持在其近(外壳)端。按钮410包括至少一个止挡元件436，其与外壳405内提供的止挡元件435和437合作以限定按钮410的各自的移动的近和远界限。按钮410包括布置其上的具有接合表面432的开口430，用以如下所述地耦接连接器400和压触头。
[0056]连接器400进一步包括电触点元件455，其布置在腔406之上。可以采用前述的任意合适的连接方式使接触元件455电耦接导线475。导线475可选地可以被溢放口470从外壳405在其退出点支撑。接触元件455提供了接触开口445，其定义为接收电触点，如压触头，以及其可以为如前所述的不对称形，具有远窄端450和近宽端451。外壳405的底部表面630提供了布置于其上的孔620，其暴露接触开口445给连接器400的外部以帮助压触头插入到连接器中。
[0057]可以通过按下按钮410而实现接合压触头进入连接器400，例如，可以应用足够的手指压力给按钮表面411使得克服螺旋弹簧420的偏压，因此将按钮410从图4所示的远端锁止位置移动到图5所示的近端开启位置。开口430相应地向近端移动，暴露接触开口445的宽近端451并如图6D最佳所示的帮助压触头插入到连接器400中。在压触头插入之后，随后可以释放按钮410，于是螺旋弹簧420上的偏压力导致按钮410向远端移动，导致接合表面432机械地接合并且电耦接压触头于接触开口445的窄端450，其如图6C最佳所示。相反的，通过压下按钮410，所述的与连接器400接合的压触头可以脱离，导致接合表面432向近端移动，释放压触头并帮助其从连接器400的移除。当压触头移除后，可以释放按钮410，以准备连接器400供随后使用。也可以构思在该实施例中，在按钮和电触点元件之间增加组件(如连杆或齿轮)以实现机械优点并改善夹紧或连接力。
[0058]参照附图7，8，9A和9B描述了根据本发明的另一实施例，其中示出了一种ECG导线连接器700，其具有提供腔706的外壳705，以及枢转地布置其上的具有激励端715、外部按钮表面711、枢轴712以及接合区域716的杆710。连接器700也可以包括盖905，盖905可选择地包括如前所述的指示标记910。如前所述的，可以采用任意合适的非导电材料构造外壳705、杆710和盖605。
[0059]如图7和8所示，杆710包括布置其上的枢轴孔713，用以枢轴地接合外壳705提供的枢轴销714。杆710的激励端715被板簧720在向外方向上偏压，板簧720通过杆710的表面726而保持在杆端，以及通过外壳705的表面725而保持在外壳端。附加的或替代的，板簧720可以包括保留在杆表面726和/或外壳表面725所提供的至少一凹槽(未示出)中的至少一突起(未示出)。杆710的接合区域716包括接合表面732，用以下面将进一步描述的耦接连接器700和压触头。
[0060]连接器700进一步包括电触点元件755，其布置在腔706的上部。可以采用前述的任意合适的连接方式使接触元件755电耦接导线775。导线775可选地可以被溢放口770从外壳705处支撑在其退出点。接触元件755提供了接触开口745，其限定为接收电触点，如压触头，以及其可以为如前所述的不对称形，具有窄端750和宽端751，其如图8和9B最佳所示。外壳705的底部表面930提供了布置于其上的孔920，其暴露接触开口745给连接器700的外部以帮助压触头插入到连接器中。
[0061]可以通过按下按钮表面711而实现接合压触头进入连接器700，例如，可以应用足够的手指压力给按钮表面711使得克服板簧720的偏压，因此导致杆710的接合区域716从图7所示的关闭位置摆动到图8所示的开启位置。因此暴露了接触开口745的宽端751从而帮助压触头插入到连接器700中。容易理解的是，随后可以释放按钮表面711，于是板簧720上的偏压力导致接合表面732向插入的压触头移动以机械地接合并且电耦接压触头于接触开口745的窄端750。相反地，通过压下按钮710，所述的与连接器700接合的压触头可以脱离，导致接合表面732摆动远离压触头(即，远离接触开口745的窄端750)，释放压触头并帮助其从连接器700的移除。当压触头移除后，可以随后释放按钮表面711，以准备连接器700供随后使用。
[0062]现在参照图12A-C以及图13A-D，一种ECG电极连接器1320包括具有上部元件1324以及下部元件1326、并在其间定义的内部腔1328的外壳1322。外壳1322采用非导电材料制造，如，与其中的导电元件电绝缘的注模聚合物。上部元件1324和下部元件1326是以任意合适的结合方式(例如但不限于，粘合，超声焊接或热焊)而相互依附的独立组件。上部元件1324和下部元件1326形成外壳1322的非导电部件。
[0063]外壳1322包括导线终端1330，其以任意适合的连接方法电连接导线1304的各自端，方法包括但不限于、卷边、钎焊或焊接。外壳1322支撑接触元件1332，其电连接于导线终端1330。接触元件1332和导线终端1330可以一体形成。接触元件1330限定了形成于其上的、并与外壳1322的内部腔1328相通的接触开口1334。接触开口1334包括第一接触开口部1334a和第二接触开口部1334b。第一接触开口部1334a限定了内部尺寸或直径，其大于第二接触开口部1334b相应的内部尺寸或直径。
[0064]外壳1322进一步包括枢转地与其连接的杆1340。杆1340包括激励端1336。通过偏置元件1338，杆1340向第一位置偏压。杆1340包括从其上突起的接合区域1336a，以便当杆1340在第一位置的时候延伸穿过接触开口1334的第一接触开口部分1334a。使用中，杆1340可以活动到第二位置，其中其上的接合区域1336a并不阻挡或延伸穿过接触开口1334的第一接触开口部分1334a。例如，临床医生可以应用手指压力给激励端1336，其足够克服偏置元件1338的偏压力，因此导致接合区域1336a移动到此处描述的第二位置。
[0065]ECG电极连接器1320适用于连接传统的卡扣式生物医学电极(未明确示出)。典型的卡扣式生物医学电极结合了与电极基座以横向关系延伸的电极凸缘或基座和阳压触头或终端。阳压触头终端可以具有球根状头，因此终端的上部与终端的下部相比具有更大的横截面的尺寸。据此，在使用中，当电极连接器1320的杆1340在第二位置的时候，卡扣式生物医学电极的阳压触头终端的头可以插入到接触开口1334的第一接触开口部位1334a，因此杆1340的激励端1336可以被释放，使得偏置元件1338相对于凸压触头的头(未示出)移动杆1340的接合区域1336a，以推进或促使压触头的下部进入接触开口1334的第二接触开口部分1334b。偏置元件1338的偏压力帮助保持压触头在接触开口1334的第二接触开口部分1334b中，因此抑制了生物医学电及从ECG电极1320移除或脱离。
[0066]可以理解，对于此处公开的实施例可以有各种修改。进一步的，上述公开的变形和其他特征和功能，或其替代物，可以期望地结合入许多其他不同的系统，工具或应用中。各种目前无法预料或不曾预料的，但随后可能由本领域技术人员得出的替代、修改、变形或改进，其也应包括在权利要求书中。
