International ClassesA61M 035/00B05B 009/00 B65D 001/32 B65D 035/56 AbstractA self-contained emergency eye wash station for dispensing eye wash fluid contained in a flexible container comprises a housing, a reservoir, and a platen. The housing supports the flexible container and supports a nozzle in fluid communication with the flexible container. The nozzle dispenses the eye wash fluid from the flexible container. The housing includes a drain capturing the eye wash fluid dispensed from the nozzle. The reservoir collects the eye wash fluid captured by the drain, and the reservoir is slidably mounted to the housing. The platen is connected to the reservoir. The platen is slidably movable relative to the housing and is located immediately above the flexible container. The platen presses downward on the flexible container with a downward force proportional to a weight of the eye wash fluid collected in the reservoir. The transfer of the weight of the eye wash fluid collected in the reservoir to the platen maintains a constant flow of eye wash fluid dispensed from the nozzle.Other References
