An eyewash fountain nozzle unit 1 comprising, an eyewash fluid outlet port shaped 2 to define a first eyewash fluid outlet opening 3, a second eyewash fluid outlet opening 4, and a flow constriction eyewash fluid outlet opening 5 between the first and second eyewash fluid outlet openings. The cross-sectional area of the flow constriction opening is less than the cross-sectional area of either of the first and second openings and permits formation of a bridging body (e.g. a "web", 17 Fig 3) of eyewash fluid between respective upwardly directed eyewash fluid discharge streams formed by the first and second openings. The first and second openings may be arranged symmetrically about the flow constriction opening. Fluid diverger spokes 6 may be used and may be a wedge shape. The openings may be in the form of a labyrinth slot (22 23 Fig 5-7) with a constriction opening (24). The constriction outlet restricts the flow of water directed at the nose of the user. A method of washing human eyes is also claimed using the above apparatus. |
