    摘要： A blood pump for use in CPB and other heart surgeries includes a reusable motor stator element which is enclosed in a disposable, sterile pump housing. The reusable, non-sterilized motor stator element is completely encased by the pump housing so that the motor stator can be reused without sterilization. The sterile housing allows the blood pump to be placed closed to the patient and within the sterile surgical field. The placement of the blood pump close to the heart during heart surgery greatly reduces the priming volume of the system thereby reducing the amount of saline or drugs which are introduced the patient's blood. The sterile housing may be evacuated to reduce the risk of emboli which may occur due to the failure of a seal.

    摘要翻译： 用于CPB和其他心脏手术的血泵包括可重复使用的电动机定子元件，其被封装在一次性无菌泵壳体中。 可重复使用的，无消毒的电动机定子元件被泵壳完全包住，使得电动机定子可以在不进行灭菌的情况下重复使用。 无菌外壳允许将血泵放置在患者身体和无菌手术区域内。 在心脏手术期间将血泵置于心脏附近大大降低了系统的引发体积，从而减少引入患者血液的盐水或药物的量。 无菌外壳可以被抽空以减少由于密封失败而可能发生的栓塞的风险。
