摘要： The present invention pertains to a blood pump device which comprises a blood pump having blood transport ports and cannulae connected to the ports. The blood pump device also comprises a coating material covering the junction between the inner surfaces of the ports and cannulae. This forms a smooth transition so blood can flow unimpeded therefrom and collection cavities for the blood are eliminated. The invention is also related to a method of producing a smooth coating. The present invention is a blood pump device comprising a second portion having a stator mechanism and a rotor mechanism disposed adjacent to and driven by the stator mechanism. The second portion has a journal disposed about the rotor mechanism to provide support therewith. The second portion has an impeller disposed in the chamber and a one-piece seal member for sealing about a shaft of the impeller. The seal member is fixedly attached to the journal so that the seal member is supported by the journal. The present invention is also related to means for providing power to the blood pump so that blood can be pumped through a cannulae. The providing means includes a controller having means for sensing pump failure and an output terminal for actuating a safety occluder in an event of pump failure. Preferably, there is a safety occluder device disposed about the cannulae and in communication with the output terminal. Preferably, the blood pump comprises a motor having stator mechanism and a rotor mechanism driven by the stator mechanism. The sensing means comprises means for determining back electromagnetic force within the stator mechanism. Preferably, the controlling means has means for providing signals indicate of stator current and rotor speed, respectively. The providing means is in communication with the means for determining back electromagnetic force in the stator mechanism.
摘要翻译：本发明涉及一种血液泵装置，其包括具有血液输送口的血液泵和与端口连接的插管。血液泵装置还包括覆盖端口的内表面和套管之间的接合处的涂层材料。这形成平滑的过渡，因此血液可以不受阻碍地流动，消除了血液的收集腔。本发明还涉及一种制备光滑涂层的方法。本发明是一种血泵装置，包括具有定子机构的第二部分和与定子机构相邻并由定子机构驱动的转子机构。第二部分具有围绕转子机构设置的轴颈，以便为其提供支撑。第二部分具有设置在室中的叶轮和用于围绕叶轮的轴密封的一体式密封构件。密封构件固定地连接到轴颈上，使得密封构件由轴颈支撑。本发明还涉及用于向血液泵提供动力以使血液能够通过套管泵送的装置。提供装置包括具有用于感测泵故障的装置的控制器和用于在泵故障的情况下致动安全闭塞器的输出端子。优选地，存在围绕插管设置并与输出端子连通的安全闭塞器装置。优选地，血泵包括具有定子机构的马达和由定子机构驱动的转子机构。感测装置包括用于确定定子机构内的反向电磁力的装置。优选地，控制装置具有分别提供定子电流和转子速度的信号的装置。提供装置与用于确定定子机构中的反向电磁力的装置通信。
