Description

泵装置
技术领域
本发明涉及机械工程和精密机械，尤其可以有利的用于医学领域。
背景技术
在这方面，本发明主题为根据权利要求1的前序部分所述的一种泵装置。
在现有技术中，泵装置尤其因用于人体血管而日益为人所知。所述泵可以用于，例如，短期心脏支撑，用以在病人出现心源性休克(急性心肌梗死)后缓解心肌。在这个过程中，有时作为经股动脉植入的微型轴流泵使用。
例如，在EP2047872A1中已知这样的泵装置。其中公开的泵装置包括泵，容置泵的护套，并且护套具有远端吸入口和近端流出口，泵在运行中产生从远端吸入口至近端流出口的驱动流。这样在吸入口和流出口之间延伸出了流道。在这方面，泵可以设置于护套的第一流体密封部分内，该第一流体密封部分构成外壳的PU包衣并且具有远端吸入口。进一步的，提供了护套的第二流体密封部分，该第二流体密封部分包括近端流出口，并且为流出软管形式。流出软管与PU包衣连接，该连接具有材料连续性。泵装置设置成转子形式的泵，例如可置于心室时，流出软管自心室延伸至主动脉。
所有经由流出软管的流出口进入主动脉的血液都通过吸入口进入护套形成的流道并由此流经转子。也就是说，泵输送的流体等同于由流出口流出的流体。
文件DE4124299A1、DE102004054714A1、WO2007/112033A2和US2008/132748A1的主题也是根据上述原理工作。
由于所有血液与泵直接接触，这要求在制造泵时做出特别大的努力，来减少泵的运动部件对血液的损伤效果。这种血液损伤效果被证实存在于运动和静止的泵部件的直接机械剪切中以及流体通过流道(如上所述)时存在的剪切应力场所产生的剪切中。泵的几何尺寸也由此而增大，因而不能用于微创手术中。
发明内容
本发明的根本目的是减小经过泵的血液或者流体损伤的风险。需要特别注意的是下述泵装置用于医疗领域时的材料选择。所述材料应该合理地满足生物相容性的要求。除了上述的实现方式，与异物表面的交互作用成为血液损伤的第三大方面，并已经被充分地研究了一段时间。
根据本发明，在第一部分和第二部分之间引入了附加的流入口，所述第一部分和所述第二部分彼此相对设置，以使流入口在可压缩泵的近端与流道相通。在这方面，附加的流入口也可形成为流入通道，所述流入通道的流入口在泵的远端或近端或与泵在同一水平，但仅仅在可压缩泵的近端与流道相通。
借助于本发明的特征，流经泵的驱动流流过流道，并经过流入口的开口朝向流出口流动，因而产生相对于流入口内部流体压力的压降，致使流体从流入口被吸入流道。因而，由于在流入口加入了附加的吸入流，从流出口流出的总流大于直接流经泵并由此输送的驱动流。
由于驱动流形成的吸入效应，产生了吸入流，这也发生在一些类型的涡轮或喷水泵中。在吸入效应中，推动力通过流体的摩擦或粘性或紊流混合从驱动流传输至吸入流。这样，产生了粘性、紊流剪切应力。动力流的推动方向被传输至待被输送的吸入流的介质颗粒，这些颗粒被传送至护套内的下游区域。
实质上，借助于本发明的特征，喷射泵原理得以实现，驱动流直接流经泵并连同由附加的流入口流进的吸入流一起被输送。
在这方面，流入口位于第一部分和第二部分之间，并具有入口，该入口可在泵的近端或远端，若该入口位于流出口的远端则更有利的。只是，流入口进入流道的开口应在泵的近端，以便很好地利用由驱动流产生的吸入效应。
可以理解的是，压缩泵优选径向可压缩泵或泵装置。在这方面，泵处于展开状态时，导管的内径小于第一部分和第二部分或外壳，泵或第一部分和/或第二部分和/或外壳和/或转子的构成使泵可被引导至导管内的目标位置。这样的泵或泵装置可由，例如，文件EP2047872A1，WO2010/063494A1，US61/120,095或WO2010/127871和US61/175,519A1中得知。
吸入口和流出口之间形成流入口是特别有利的。
护套的第一部分和第二部分可以一体成型，也可以作为相互分开的组件。
在一个实施例中，第一部分近端的横截面小于第二部分远端的横截面。输送流由此汇聚在第一部分近端的横截面区域中，并且可以携带附加的介质进入第二部分，所述介质至少可以通过第二部分远端的横截面的剩余区域流入。
在另一实施例中，第一部分的横截面向其近端聚拢。由于这种聚拢，第一部分在其近端呈喷嘴形状。这带来效率的提升，并且因而增加吸入的吸入流。另外，该特征帮助达到了缩小总体泵装置的效果。
在另一实施例中，第二部分的远端和第一部分的近端重叠，例如第二部分的远端比第一部分的近端更靠近远端。在这方面，如果位于第一部分和第二部分之间的流入口在不同情况下形成吸入流道或形成从第二部分的远端向第一部分的近端的通道，这样是有利的。优选的，吸入流在这里几乎与驱动流的输送方向同轴，通过吸入流道进入流道并流向流出口。在这方面，由于吸入流道的主轴优选地朝向待输送的流体，朝向流出口的驱动流推动力已经被传输至吸入流。这带来效率的提升。
在另一实施例中，第二部分的远端比第一部分的近端更靠近近端或与所述第一部分的近端处于同一水平。由于存在间隔，汇聚的驱动流从第一部分的近端流出后遇到压力不同且方向不同的流体，从而汇聚的输送流，如同更高密度的流体，流入由第二部分远端限定的第二部分起始端，并且携带位于第一部分和第二部分之间的流体。因此，总流比流过泵的驱动流更多。然而，在这方面，必须注意，第二部分的远端与第一部分的近端之间的间隔保持在很小，从而不产生输送流相对于护套外面流体的任何离散。该间隔应该在第一部分近端流出口的直径的约0到1/4之间。
在另一实施例中，第二部分包括至少一个由柔性材料制成的部分区域。因此，以第二部分置于心室和血管之间为例，其中心室和血管通过有节奏开和的瓣膜连接，第二部分可以被压入瓣膜，并且流体因而可以在有节奏的瓣膜运动下依次输送。例如，PU，PE，PP，硅树脂(silicone)或聚对二甲苯可以作为合适的材料，条件是其满足机械和几何要求，以及生物相容性要求。
在另一实施例中，泵装置中具有容置泵的外壳。这尤其适合当泵是可压缩泵时，可借助导管将泵连同外壳一起输送到其工作处。该外壳可以由，例如镍钛合金(Nitinol)制成。
当有外壳时，第一部分可以被制成外壳的包壳或包衣，仅外壳的部分区域，优选轴向的部分区域，必须带有流体密封包壳或包衣。适合制成包衣或包壳的材料已经在描述由柔性材料制成的第二部分时指出。
在另一实施例中，外壳在泵的近端具有缩窄和/或鼓起。在这方面，缩窄可以理解为外壳横截面相对于容置泵的外壳区域的聚拢。鼓起为外壳横截面相对于缩窄或相对于容置泵的外壳区域的扩大。第一部分的聚拢部分或第二部分的较大的横截面可以借助于这样一种形状用一种特别简单和有利的方式实现。第二部分也可以连接至外壳。
在另一实施例中，第一部分和第二部分相互连接，该连接具有材料连续性；或优选二者一体成型。
在另一实施例中，第二部分形成为流出软管。
在另一实施例中，第一部分、第二部分或任何外壳，包括支撑元件，支撑元件例如支撑环，塑料线，金属线，连接支柱或优选的可压缩套管，用于将第一部分和第二部分隔开。这样，第二部分的表面不会因吸入流流过流入口而吸附在第一部分的表面，打断吸入流，或者说，这样保证附加的流入口在泵运行时一直打开。在这方面，支撑元件连接至第一部分或第二部分，以使它们可以连同泵一起被压缩。这可以通过弹性支撑元件或以超弹性材料或例如镍钛合金的记忆材料制成的支撑元件来实现。
第二部分在流入口区域可以进一步具有支撑环，所述支撑环保证第一部分和第二部分在流入口区域有间隔，以使第二部分的表面不会因吸入流流过流入口而吸附在第一部分的表面上，打断吸入流。当第二部分由柔性材料，例如流出软管制成时尤其有利。
在另一实施例中，第二部分具有套管，套管包括附加的流入装置或部分包括附加的流入口。所述套管可以作为附加的异形部件被连接至，例如，第二部分的柔性区域。在这方面，如果，套管是稳定形状并且因而相对于处于工作状态的流体形成合适阻尼，以使吸入流被套管引导并且流入流道，则是有利的。该工作状态由，例如，泵装置在身体中的工作处展开所限定。
也可以使用附加的软管部分或管状物代替套管。
在另一实施例中，泵为可压缩泵，从而更轻便地将泵导入血流或血管中。
如果泵是紧固于可驱动该泵的可转动轴上的轴流泵，则是更有利的。

图1示出一种泵装置1可能的应用。泵装置1包括在血管2内延伸的细长导管，并且有一轴在导管内延伸用以驱动泵装置1中的泵，该泵形成转子。泵装置的近端(观察时无导管)位于血管2中，而包括泵在内的泵装置1的远端位于心室3中。血管2被血管壁4限定。有节奏开合的瓣膜5进一步限定心室3并且可使血液自心室3流入血管2中。
除了根据上述信息应用泵装置之外，泵装置还有进一步的应用。泵可以例如用于身体中不同的血管来提高输送性能。
参考图2解释本发明的泵装置的运行模式。泵装置10包括转子形式的泵11。泵11由所示的但未编号的轴带动旋转，因而可以运输一驱动流QT。泵装置10具有护套12，护套12包括第一部分12a和第二部分12b。吸入口13位于第一部分12a，通过吸入口，流体可以进入第一部分12a的内腔，该流体被泵11吸入并且作为驱动流QT朝向流出口14运输。护套11限定了位于吸入口13和流出口14之间的流道S，所述流道包括第一部分12a的全部内腔并且包括第二部分12b的部分内腔。
第一部分和第二部分在第一部分12a的近端和第二部分12b的远端之间重叠。流入口15被该重叠所限定，通过所述流入口15，流体可以由第一部分12a内腔外部的区域进入流道S。由于泵输送驱动流QT，在第一部分的近端16的区域17中出现压降。这在图3中示出。
由于区域17中的压降，更多流体通过流入口15以朝向流出口14的方向被吸入并在接近第一部分的近端16的位置作为吸入流QS进入流道。
第一部分12a和第二部分12b都包括内腔。在这方面，第一部分12a的内腔具有横截面面积A1；第二部分12b的内腔具有横截面面积A2。在本实施例中，横截面A1和A2在所述第一部分和第二部分的总长度上各自保持不变；然而，这不是必须的特征。由于流道在第二部分12b的远端和第一部分12a的近端之间平行于驱动流延伸，并形成流入口15，吸入流已经受到朝向流出口14方向的推动力作用。在流出口14流出的单位时间的体积QA大于流过泵的驱动流QT，这由于有额外的吸入流QS。
图4描述了另一个实施例中的泵装置。泵装置20位于血管中，血管被血管壁4限定。泵装置20的远端位于瓣膜5的远端；近端位于瓣膜5的近端。
泵装置20包括可压缩的转子21，该转子21一侧紧固在轴22上。轴承位于转子的近端。转子21被外壳23环绕，外壳23可由镍钛合金制成。外壳包括独立的线，镍钛合金制成的线或支柱，可以相互交叉产生菱形图案。流体可以流过该菱形并到达转子21。
外壳23被包壳24以流体密封方式部分覆盖。在这方面，包壳24延伸长度L24，以使转子驱动的驱动流QT归拢并在包壳24的近端离开外壳23，流向流出口29的方向，流出口设置于流出软管25。
本实施例中，泵装置20的包壳24形成护套的第一部分；流出软管25形成护套的第二部分。流出软管的远端被紧固至外壳23并且比护套24的近端更靠近远端。
护套34在转子21区域沿近端方向聚拢。因而，护套24在转子21区域形成的内腔的横截面面积A1D大于护套24近端的横截面面积A1P。因此产生喷嘴效应，根据文丘里管原理，喷嘴效应加速驱动流QT，使其在护套24近端以更快的速度向流出口29的方向流动。位于护套24和流出软管25之间的吸入流道26通过入口27导通。可以从图4中看出，提供了多个入口27，入口在流出软管的远端区域被设计为具有圆形截面。由于离开的驱动流QT处的压力下降，吸入流QS通过入口27和吸入流道26被吸入，并流入流道S，流道S输送所有待输送流至流出口29。
在泵的工作状态下，形状稳定的支撑环28位于入口27近端和流出软管25的径向周边。这样，防止了由产生的吸入流引起的流出软管25的表面吸住护套24。因而，吸入流道26保持开放并且驱动流QT使更多流体通过吸入流道26被吸入流道S。
根据本发明又一个实施例的泵装置如图5a所示。泵装置30包括转子31，所述转子31的两侧，即远端和近端，都支撑在轴32上。转子31被置于外壳33中，外壳33被PU包衣34部分套住。在这方面，PU包衣34的长度L34延伸至位于转子31近端的邻近区域。外壳33具有缩窄33a并且在缩窄33a的近端膨胀形成鼓起33b。在鼓起33b区域中，流出软管35被连接至外壳33，并且该连接具有材料连续性。鼓起33b和缩窄33a被相互隔开，间隔d沿着轴32的方向为缩窄33a直径的约0-1/4。在这方面，由于驱动流QT离开PU包衣34的近端且被转子31驱动，选择间隔d，以使吸入流QS得以从PU包衣34和流出软管35之间形成的流入口36被吸入。离开包壳34的驱动流QT以压力P1流出。在包壳34外部施加的压力P2小于压力P1。吸入流QS由于该压力差而被吸入流入口36，并且通过流出软管朝向流出口39输送，在那里作为总流QA以压力P3被排出，压力P3大于压力P2。在这方面，总流QA小于驱动流QT。
即使在转子31远端的吸入口和流出口39之间延伸的流道S对处于PU包衣34的近端和流出软管35的远端之间的流体是可渗透的，流入口36仍根据驱动流的流动过程与流道相通。如果驱动流的流速相对高，事实上，它将直接进入流出软管。
由于在转子31的远端提供了吸入口之外的流入口，从流出口39流出的总流QA中的一部分流体并不经过转子31，所以没有被转子31引起血液损伤的风险。
图5b再次示出了图5a实施例中的泵装置30。可以看出，在PU包衣34的远端具有横截面面积A1D，该面积比位于PU包衣34近端的横截面面积A1P大。PU包衣34环绕而成的内腔因而聚拢，具有效率提升的作用。流出软管35的内腔的横截面面积A2D相应地大于横截面面积A1P。因而，流入口36至少被横截面面积A2D减去横截面面积A1P之后剩下的面积所限定。所述流入口相应地与流道S相通。
图6示出了又一个实施例中的泵装置。在这方面，省去了对轴和泵传动的详细描述。泵装置40包括转子41，同时包括护套的第一部分42a和第二部分42b。为泵41供给流体的吸入口43位于第一部分42a的远端。给泵41供给的流体被加速并且作为驱动流QT在第一部分42a的近端被排出。第二部分42b由弹性区域420b组成，弹性区域420b连接至具有稳定形状且在工作状态下坚硬的可压缩套管421b。可压缩套管421b通过塑料线或金属丝422b连接至第一部分42a。横截面以聚拢方式从套管421b的远端延伸至套管421b的近端的，与驱动流QT配合，具有从流入口45吸入吸入流QS的效果，流入口45在套管421b和第一部分42a之间形成，吸入流QS在流道S中与驱动流QT合并，并作为总流QA从流出口44流出。相应地，从图6中可明显看出，流入口45与流道S相通。
图7示出了再一个实施例中的泵装置。泵装置50包括的泵51为具有转子的轴流泵。进一步的，提供了可分为第一部分52a和第二部分52b的护套52。在这方面，第一部分和第二部分相互连接，该连接具有材料连续性，或二者一体成型制成。为转子供给流体的吸入口53位于护套52的远端，以使驱动流QT在转子的工作状态下被输送。驱动流QT朝向流出口54被输送。流入口55位于第的一部分52a和第二部分52b之间，吸入流QS受驱动流QT影响，可以通过流入口55进入由护套52限定的流道S。本实施例的特殊特征在于，与先前示出的实施例相比，先前示出的实施例中的第一部分相对于第二部分为单独的组件，而本实施例的护套52是一体成型。
流入口入口的一些不同的几何形状如图8a-8c所示。
图6对应的实施例中的一种横截面如图8a所示。可以看到的是，吸入口543具有横截面面积A1P。邻近吸入口的近端，即进一步进入平面图，套管421b具有在其最外围测得的横截面面积A2D。塑料线422b将套管421b连接至第一部分42a。
图5a对应的实施例中的横截面在图8b中示出。可以看出，吸入口33被PU包衣34限定。PU包壳34同时限定了在转子区域横截面面积为A1D的内腔。另外，可以看出轴32处于吸入口33的中央。转子近端(对照图5a)，由线、镍钛合金线或支柱而制成的外壳33聚拢至由缩窄33a限定的横截面面积A1P。在近端，外壳33变宽形成鼓起33b，流出软管35在鼓起区域连接至外壳。可以清楚的看出，参照图8b中所示，作为吸入流的流入口的区域36位于流出口35和PU包衣34之间并。
图4对应的实施例中的横截面在图8c中示出。在这方面，所示为支撑环28所处层面(level)的横截面。可以看到，由第一部分的包壳24限定，且具有横截面面积A1D的内腔。驱动流朝向近端方向流经包壳24的内腔，驱动额外的流体通过吸入流道26被吸入，吸入流道26位于包壳24和流出软管25之间。流出软管25在这个区域内具有横截面面积A2D。支撑环28清晰可见，还可看到，连接支柱28a连接支撑环至包壳24。所述支撑环由多个段28b组成，这些段可以变成折叠状态，以借助导管引入泵装置。
