    • A device for infusing a secondary fluid through a primary fluid administration set without mixing the primary and secondary fluids is disclosed. Two pistons which are releasably locked in tandem slide within a chamber having an output port, dividing the chamber into two portions. The portion having the outlet port contains the secondary fluid. One piston faces the secondary fluid, while the other has a bore which is in fluid communication with the primary administration set. The pistons can be decoupled, allowing them to move apart to create a third portion in the chamber which can fill with fluid from the primary administration set through the piston which is not in contact with the secondary fluid. When the latter piston is locked in position, a pump in the primary administration set generates pressure in the portion between the pistons. This pressure drives the piston facing the secondary fluid, forcing the secondary fluid out of the chamber and into the patient.
    • 公开了一种用于在不混合初级和次级流体的情况下通过主流体给药装置输注次级流体的装置。 在具有输出端口的腔室内可释放地锁定在串联滑动件中的两个活塞将腔室分成两部分。 具有出口的部分包含二次流体。 一个活塞面向次级流体,而另一个活塞具有与主要给药装置流体连通的孔。 活塞可以被去耦合,允许它们分开以在腔室中产生第三部分,该第三部分可以填充来自主要给药装置的流体通过不与次要流体接触的活塞。 当后一活塞被锁定就位时,主要给药装置中的泵在活塞之间的部分产生压力。 该压力驱动活塞面向次级流体,迫使次级流体离开室并进入患者体内。

    • A binding mounting apparatus having a baseplate which is mounted to a board surface of a snowboard or the like. A pivot stem with an enlarged head portion is secured to the baseplate. A mounting plate has at least one mounting through hole and a stem through hole. The pivot stem is positioned within the stem through hole. Such stem through hole is sized large enough for the pivot stem to fit within the stem through hole and small enough for the enlarged head to prevent the mounting plate from moving beyond or traveling over the enlarged head portion when the apparatus is tightened. A riser ring is positioned about the mounting plate. A face plate is mounted on the riser ring. The face plate has at least one face plate through hole which can be aligned with a corresponding mounting through hole so that the binding mounting apparatus can be tightened with respect to the board surface and so that all elements of such apparatus can be tightened with respect to each other.
    • 具有安装在滑雪板等的基板表面上的基板的装订装置。 具有扩大的头部的枢轴杆固定到基板。 安装板具有至少一个安装通孔和杆通孔。 枢轴杆位于杆通孔内。 这种杆通孔的尺寸足够大以使枢轴杆装配在杆通孔内,并且足够小以使扩大的头部能够防止当装置被紧固时,安装板移动超过扩大的头部或越过扩大的头部。 提升管环围绕安装板定位。 面板安装在提升环上。 面板具有至少一个面板通孔,其可以与相应的安装通孔对准,使得装订安装装置能够相对于板表面被紧固,使得这种装置的所有元件可相对于 彼此。
