摘要： A valve actuator that moves in a catheter assembly between a first position where a valve is closed and a second position where the valve is open, the valve actuator including a shaft portion at a distal end of the valve actuator that is configured to pierce the valve, a mating portion at a proximal end of the valve actuator that is configured to engage a Luer device, a diameter reduction region that connects the shaft portion and the mating portion, and a plurality of windows that extend through the valve actuator for flushing fluid, the plurality of windows being disposed in the diameter reduction region, wherein each of the plurality of windows does not extend a full length of the diameter reduction region.

摘要： A catheter and introducer needle assembly, including a flexible catheter and a catheter hub having an outer surface portion. The assembly includes an introducer needle disposed in the catheter, a needle shield having a resilient clip adapted to flex between first and second positions. The resilient clip includes a cantilevered arm with a pawl. In the resilient clip's first position, the cantilevered arm is flexed so that the pawl frictionally contacts the catheter hub's outer surface portion to retain the needle shield with the catheter hub. In the second position, the pawl no longer frictionally contacts the hub's outer surface, thereby permitting needle shield displacement relative to the catheter hub.

摘要： A catheter and introducer needle assembly, including a flexible catheter and a catheter hub having an uninterrupted outer surface portion, a Luer-connecting feature, and a disabling feature. The assembly includes an introducer needle disposed in the catheter, a needle shield having a resilient clip adapted to flex between first and second positions in a plane perpendicular to the introducer needle. The resilient clip includes a cantilevered arm with a pawl. In the resilient clip's first position, the cantilevered arm is flexed so that the pawl frictionally contacts the catheter hub's uninterrupted outer surface portion and frictionally retains the needle shield with the catheter hub, and the pawl is axially aligned with and spaced apart from the disabling feature. In the second position, the pawl no longer frictionally contacts the hub's uninterrupted outer surface, thereby permitting needle shield displacement relative to the catheter hub.
