摘要： Pumps wherein smooth surfaced rotators cause propulsion of a delicate fluid without significant damage to the fluid. The pumps may be used as heart pumps, blood pumps, and pumps for all types of fluids in connection with the maintenance of life or biological functions in a human or animal subject in many in vivo, ex vivo, or in vitro applications, or for any other application requiring gentle fluid handling. The pumps may be actuated by internal or external electric motors, and the rotators may be configured to converge mutually as an inverse function of distance from the axis of the rotators. The rotators may be connected together, by pins passing through the fluid passages, for mounting and driving as a unit, or may be mounted and driven independently to further eliminate the possibility of damage to the fluid by rotator-connection members.
摘要翻译：其中光滑的浮雕旋转器引起精细流体的推进而对流体没有显着的损害。在许多体内，离体或体外应用中，泵可以用作所有类型的流体的心脏泵，血泵和泵，用于在人或动物受试者中维持生命或生物功能，或用于任何其他需要温和流体处理的应用。泵可以由内部或外部电动机来驱动，并且转子可被构造成相互转动，作为与转子轴线的距离的反函数。旋转器可以通过穿过流体通道的销连接在一起，用于作为一个单元的安装和驱动，或者可以独立地安装和驱动，以进一步消除由旋转器连接构件损坏流体的可能性。

摘要： The disclosure is directed to a surgical bridge for supporting incision sutures under continuous tension. The bridge is elongated in shape, including two feet which engage the surface of a patient's skin on opposite sides of an incision, and which are connected by a bridge portion that overlies the incision. The bridge further includes a pair of resiliently flexible cantilevered arms each of which defines a suture support point elevated from the skin surface to preclude cutting or slicing of the patient's skin by the suture. In one embodiment, the suture bridge is made from two interlocking pieces, which enables the advantageous usage of two materials having different resilience, and also simplifies manufacture of the device. Improved structure is also disclosed in conjunction with the suture bridge for effecting tying or securing of a suture end to the bridge quickly and easily.
摘要翻译：本公开涉及用于在连续张力下支撑切口缝合线的手术桥。桥梁的形状是细长的，包括两个脚，其接合在切口的相对侧上的患者皮肤的表面，并且通过覆盖在切口上的桥接部分连接。桥梁还包括一对弹性柔性悬臂，每个弹性柔性悬臂限定从皮肤表面升高的缝合线支撑点，以阻止缝合线对患者皮肤进行切割或切片。在一个实施例中，缝合桥由两个互锁件制成，这使得能够有利地使用具有不同弹性的两种材料，并且还简化了该装置的制造。结合缝合桥还公开了改进的结构，以便快速且容易地将缝合线绑定或固定到桥上。
