Model SP65 AXION MSR eye face wash inverted flow design is the only product on the market that provides a medically superior response consistent with all EMT, emergency room and doctor's 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 drains. Eyewash streams provide zero vertical Velocity™ stream engineering with even laminar flow for enhanced comfort, stability and effectiveness.
