A splashback shield for attachment to a syringe for wound irrigation includes a generally dome-shaped shield with a conduit or tunnel through the top that narrows to form a nozzle as it extends substantially inside the shield. A number of air vents or passageways surround the conduit so when submerging and re-filling the syringe with irrigant with the shield attached any air trapped inside the shield escapes rather than drawn into the syringe. The air vents are preferably elongate tubular passageways that narrow exiting the shield, facilitating air escaping but the irrigant mixed with any blood and contamination tends not to pass through the vents. The device is an improvement over the conventional Zerowet(R) Splashield(R) product.
