Haws model 8300-8309 combination shower and eyewash 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 Medially 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. AXION MSR also offers a new hydrodynamic shower design that minimizes the strong physical pressure that drives the water to the outer rim of normal shower heads, making the distribution equal across the entire footprint of the flow. Better use of the water flowing through the shower makes it more effective while providing a more comfortable environment by breaking the streams of water into small individual droplets.
