The invention is concerned with a wound irrigation nozzle attachment for a syringe having an elongated hollow syringe body with a fluid supply chamber defined therein and a plunger movable within the syringe body. The wound irrigation nozzle attachment according to the invention comprises an elongated nozzle body having opposite first and second ends and a fluid passageway extending therebetween, an inlet passage and an outlet passage disposed at the first end of the nozzle body and each in fluid flow communication with the passageway, the inlet and outlet passages having respective free ends disposed adjacent to one another. The nozzle attachment further includes valve means displaceable between open and closed positions, and releasable coupling means arranged at the second end of the nozzle body for releasably connecting the nozzle body to the syringe body to provide fluid flow communication between the passageway and the chamber. When the valve means is in the open position, fluid is conveyable through the inlet passage, the passageway and into the chamber in response to an outward displacement of the plunger within the syringe body and, when the valve means is in the closed position, fluid discharged from the chamber, in response to an inward displacement of the plunger within the syringe body, flows through the passageway and the outlet passage for delivery onto a wound while being prevented by the valve means from flowing from the passageway through the inlet passage. A shield member is pivotally mounted to the nozzle body and can also be slidably displaced therealong such that the shield member can be selectively positioned in an operative position adjacent to the first end of the nozzle body and transverse thereto, or in a storage position where the shield member is collapsed against the nozzle body.
