Description

具有缩小的径向尺寸的回转式容积泵
本发明涉及一种具有缩小的径向尺寸的回转式容积泵 
根据文献US2458925、FR1504705、EP0560709以及DE8121531，已知一种回转式容积泵，其包括： 
-外壳，其内布置有泵送室，以及用于所述泵送室的流体径向入口和流体径向出口； 
-具有内齿系的外齿轮，其布置在所述泵送室内，并且呈现鼠笼形状；该鼠笼形状具有由形成所述内齿系的纵向杆连接的两个末端侧板，所述外齿轮是至少部分可拆除的； 
-旋转装置，其允许所述外齿轮绕第一轴线在所述泵送室内转动，并包括中心地安置在所述外齿轮的末端侧板中的至少一个轴承； 
-内齿轮，其容纳在所述外齿轮的内部，并具有与外齿轮的所述内齿系啮合的外齿系；所述内齿轮绕与所述第一轴线平行并隔开的第二轴线旋转；并且所述外齿系包括一定数量的齿，该数量比所述外齿轮的内齿系的齿的数量要少一个；以及 
-马达，其驱动所述内齿轮绕所述第二轴线旋转。 
本发明的目的在于改进这种类型的回转式容积泵，以减小其径向尺寸，同时允许将所述内齿轮装入所述外齿轮并从所述外齿轮中移除。 
为此，根据本发明，上文所描述的这种类型的回转泵在以下几个方面是突出的： 
-所述泵送室包括可移动壁及所述旋转装置的轴承，该可移动壁可固定到所述外壳上以封闭所述泵送室，该旋转装置的轴承布置在所述可移动壁中； 
-所述旋转装置的轴承布置在所述泵送室的固定壁中； 
-所述外壳包括用于所述马达的壳体，并且固定壁将所述壳体与所述泵送室隔开； 
-驱动内齿轮旋转的马达的轴在所述轴承内穿过所述固定壁；以及 
-所述马达的轴是中空的，并由连杆带有间隙地穿过，该连杆用来将所述可移动壁固定到所述外壳上。 
优选地是，所述外齿轮的末端侧板中的至少一个末端侧板是可拆除的。 
而且，在所述连杆上布置轴承对于所述马达轴是有利的，即对于所述内齿轮是有利的。 
当根据本发明的泵用于浸在液压流体中时，为了使所述流体可以渗入该连杆，并且使所述连杆的侧壁能够被穿孔，所述连杆自身可以是中空的。这样，所述液压流体可润滑由所述连杆支撑的内齿轮的所述轴承。 
为了避免在由泵所移动的流体中避免空泡和湍流损失的风险，有利的是，所述流体径向入口和/或所述流体径向出口从所述外齿轮的一个侧板向所述外齿轮另一个侧板延伸。 
由于同样的理由，外齿轮的内齿系和内齿轮的外齿系分别至多包括五个齿和四个齿。因此，所述泵的外直径可以减小，这就相应地降低了所述泵的外围流体的速度。 
由于上述特点，将会很容易理解，根据本发明的泵可以小型化，并且同时还具有可逆流量。 
根据一个实施例，根据本发明的小型化泵可结合在人工心脏中，该人工心脏可植入到患者的心包腔内。 
因此，在将患者天生的左心室和右心室移除后，可以用这样的人工心脏来替换，该人工心脏包括主体，在该主体内布置有由至少一个液压致动器致动的人造左心室和右心室。这种人工心脏是值得注意的，因为所述液压致动器是如上文所详细说明的容积泵。 
按照惯例，如果人造心室包括连接到所述人工主体上的封闭盖板，则根据本发明，有利的是将这样的容积泵连接到该盖板上。 
通过附图中的图形，容易理解本发明是如何实现的。在这些图形中，相同的标号表示相似的部件。

图2为沿图1中的II-II线剖开的横截面图；

图4为图1～图3中的泵的透视图，其中移除了外齿轮和内齿轮； 
图5为外齿轮的透视图； 
图6为外齿轮和内齿轮组合的透视图； 
图7为装备了液压致动器的人工心脏的示意性及部分透视图； 
图8为图1～图3中的泵的俯视图，该泵安装在心室的盖板上； 
图9为沿图8中的IX-IX线剖开的截面图。 
图1～图6示出了根据本发明的回转式容积泵1，该容积泵1包括外壳2，该外壳2包括部分2M和部分2P，该部分2M内放置有电动马达3，而该部分2P内布置有泵送室4。外壳2的部分2M和部分2P由固定式内壁5彼此隔开，该固定式内壁5是所述外壳2的组成部分。电动马达3由穿过外壳部分2M的电缆6供电，并且外壳2具有固定凸耳7。 
电动马达3的旋转轴8具有轴线A8，且该旋转轴8穿过固定式内壁5以进入泵送室4。在所述轴8的部分之上，容纳在泵送室4内，紧固有延长齿轮9，该延长齿轮9有四个圆弧外齿9D。 
形成所述泵送室4的外壳2的部分2P在与部分2M相对的端部开口，并可由可移动壁10以密闭的方式封闭，该可移动壁10可固定到 所述外壳2上。 
在所述固定式内壁5和所述可移动壁10内，在所述泵送室4的一侧彼此面对地分别布置了轴承11和轴承12，该轴承11和轴承12限定了轴线13，该轴线13用于容纳在所述泵送室4内的齿轮13。 
轴线13与轴线A8平行但关于轴线A8偏移。 
齿轮13呈现鼠笼形状，该鼠笼形状具有由五个纵向杆16连接的两个末端侧板14、15，这些纵向杆16形成所述齿轮13的圆弧内齿。在附图所描述的示例中，杆16联结在侧板15上，而由于通过螺钉17连接，侧板14是可移除的，这允许侧板14与侧板15以及杆16分离。 
侧板14和15分别具有中心圆形镂空部分18和19，它们可分别与轴承11和轴承12协作，从而允许所述齿轮13在所述泵送室内旋转。 
齿轮9容纳在齿轮13的内部，且其端面9E分别在侧板14和侧板15附近，而轴8穿过侧板14的中心圆形镂空部分18。将容易理解的是，由于侧板14可移除，这就使将齿轮9装入到齿轮13内变得容易。 
当齿轮13安装在轴承11和12上，并且齿轮9布置在所述齿轮13的内部且紧固在轴8上时，所述齿轮的各自的圆弧齿9D和杆16能协作以产生泵送。 
此外，限定泵送室4的外壳2的部分2P包括两个相对的开口20和开口21，该开口20和开口21沿齿轮9的长度方向延伸，并能够各自充当用于要泵送的流体的径向入口和径向出口。 
因此，当马达3经由轴8驱动齿轮9绕轴线A8转动时，所述齿轮9的圆弧外齿9D与齿轮13的圆弧内齿16相互协作以驱动齿轮13绕轴承11和轴承12的轴线13转动。这样一来，流体穿过入口20吸入并通过出口21排出。 
如图3能清楚地可见，马达3和内齿轮9的轴8是中空的，且该轴8由连接在可移动壁10上的连杆22带有间隙地穿过。轴承23、轴 承24由连杆22支撑，并用于内齿轮9的旋转。与所述连杆22的自由端接合的螺钉25支撑在外壳2的末端上，与可移动壁10相对，以使所述可移动壁10紧贴在外壳上。 
螺钉25和连杆22是中空的，并且孔26穿透连杆22的侧壁。 
因此，当泵1浸在液压液体中时，该液体可润滑内齿轮9的所述轴承23和轴承24。 
图7中示意性地描绘了人工心脏主体30的透视图，该人工心脏可在患者天生的心室被切除后植入患者体内，并具有分别到患者右心房、左心房、主动脉和肺动脉的连接孔31到连接孔34。在此图7中，显示了在所述主体30的外部，人造心室35的位置，由支撑着用于所述人造心室的致动器37的盖板36将人造心室35封闭。 
图8和图9示出了人造心室35的盖板36的一个实施例，其中，所述致动器37由根据本发明的泵1形成，所述泵1由螺栓38穿过凸耳7而固定在所述盖板36上。
