Model 7260B-7270B wall mounted eye and face wash features the medically acclaimed AXION MSR eye face wash head assembly (patent pending). This revolutionary inverted flow design is the only product on the market that provides a medically superior response consistent with all EMT, emergency room and doctors' office protocols by sweeping contaminants away from the vulnerable nasal cavity. Traditional eyewashes irrigate from the outside edge of the eye back toward the nose, where contaminants can then be flushed into the nasal cavity through the lacrimal punctum, nature's ocular cavity drain.
