In hospitals, sinks act as reservoirs for bacterial pathogens. To assess the extent of splashing, fluorescein dye was added to four hospital sinks previously involved in pathogen dispersal to the environment and/or transmission to patients, and one sink that was not. Applying dye to the p-trap or tailpiece did not result in any fluorescent droplets outside of the drain. When applied to the drain, droplets were found in all but one wash basin, and this was more common in the absence of a drain plug. Sink design considerations to install drain plugs, reduce dripping and offset the tap may help to prevent transmission from drains.
在医院中，水槽是细菌病原体的蓄水池。为了评估飞溅的程度，将荧光染料添加到四个先前涉及病原体向环境传播和/或传播给患者的医院水槽中，以及一个未涉及的水槽中。将染料涂在 P 型弯管或尾管上，不会导致排水口以外有任何荧光液滴。当将其涂在排水口上时，除了一个洗涤盆外，所有洗涤盆中都发现了液滴，而在没有排水塞的情况下，这种情况更为常见。安装排水塞、减少滴水和偏移水龙头的水槽设计考虑因素可能有助于防止从排水口传播。
