    • A surgical irrigator comprises a pumping unit connected to a handpiece by means of elongated irrigation tubing. The pumping unit includes an impeller, batteries and a battery powered motor to drive the impeller. The handpiece includes an irrigation valve which, when depressed, opens the valve and permits irrigation liquid to flow to the surgical site. A flow sensing device is positioned at the outlet of the pumping unit. When the irrigation valve is opened, liquid flow through the flow sensing device under the influence of gravity causes a float to move with the liquid. A light source provides a light beam which is interrupted by movement of the float. This is detected by a photosensor which generates a signal to turn the motor on, causing the pump to operate.
    • 手术冲洗器包括通过细长的冲洗管连接到手持件上的泵送单元。 泵送单元包括叶轮,电池和用于驱动叶轮的电池供电马达。 手柄包括一个冲洗阀,当被压下时,它打开阀门并允许冲洗液体流到外科手术部位。 流量检测装置位于泵送单元的出口处。 当冲洗阀打开时,液体在重力的作用下流过流量传感装置会导致浮子与液体一起移动。 光源提供由浮子的移动中断的光束。 这通过光电传感器检测到,该光电传感器产生一个信号来打开电机,使泵工作。

    • A subcutaneous implantable access port is formed of a housing having a pair of noncircular fluid cavities enclosed therein by a floor, walls upstanding from the floor, and a self-sealing septum positioned above each fluid cavity. The housing is constructed of a base, a septum support, and a cap. An outlet stem exits the base and communicates with the fluid cavities therein. The outlet stem has two prongs formed in a side-by-side configuration extending outwardly from the base. The prongs are formed within the stem channels in fluid communication with the fluid cavities. Protruding radially outwardly from the portion of said prong is a barb. Fluid injected into the fluid cavity through the septum flows through a smooth transition region in which the cross-sectional area is smoothly reduced from the corresponding fluid cavity. A locking sleeve provides radial inward pressure upon the catheter which is slid over the outlet stem, thereby insuring that the catheter remains mounted on the outlet stem.
    • 皮下可植入进入口由壳体形成,该壳体具有由地板封闭的一对非圆形流体空腔,从地板垂直的壁和位于每个流体空腔上方的自密封隔膜。 外壳由基座,隔膜支架和盖子构成。 出口杆离开基座并与其中的流体腔连通。 出口杆具有从基部向外延伸的并排构造形成的两个尖头。 这些插脚形成在与流体腔流体连通的茎干通道内。 从所述叉子的部分径向向外突出的是倒钩。 通过隔膜注入到流体腔中的流体流过平滑的过渡区域,其中横截面积从相应的流体腔平滑地减小。 锁定套筒在导管上提供径向向内的压力,其在出口杆上滑动,从而确保导管保持安装在出口杆上。

    • A surgical irrigation system comprises a reusable console and a disposable pump unit. The disposable pump unit includes a pump/motor module which includes a pump and a motor for driving the pump. The module is adapted to be mechanically supported within a seat in the console. The console produces a direct voltage at a pair of terminals within the seat. When the pump/motor is placed within the seat, the console terminals are connected to contacts on the module to provide a source of direct voltage for the pump motor. In the preferred embodiment, the disposable unit includes a handpiece and an irrigation valve. A flow sensing device within the outlet tube if the pump/motor module is actuated when the valve is open to turn the motor on and drive the pump. When the valve is closed, the flow sensing device turns the motor off.
    • 手术灌洗系统包括可重复使用的控制台和一次性泵单元。 一次性泵单元包括泵/马达模块,其包括泵和用于驱动泵的马达。 该模块适于机械地支撑在控制台的座椅内。 控制台在座椅内的一对端子处产生直流电压。 当泵/电机放置在座椅内时,控制台端子连接到模块上的触点,为泵电机提供直流电源。 在优选实施例中,一次性单元包括手持件和冲洗阀。 如果在阀门打开时启动泵/电机模块以打开电机并驱动泵,则出口管内的流量检测装置。 当阀关闭时,流量检测装置关闭电机。
