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.
