Abstract: 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® Splashield® product.

Abstract: An instrument for preventing the splashback of potentially infectious fluids and body tissues during wound irrigation as well as for preventing needle impalement injury to patient or ancillary medical personnel comprises a hub (16) having a central bore (18) the proximal end of which will accept the tip of a syringe (14) and which is integrally joined to a narrow diameter tubule (22) extending from the distal end, said tubule being directed down the central longitudinal axis of a transparent, dome-shaped shield (24). Said shield is integrally joined at its proximal end around the hub and gradually enlarges in diameter towards its distal end, terminating in a circular rim (36). Said shield, when placed adjacent to a wound (40) to be irrigated, will effectively contain potentially infectious splashback (46) and prevent said splashback from contacting irrigator or other personnel, as well as protecting the patient and medical personnel from impalement injury due to contact with a needle.
