ZEROWET is the leader in wound irrigation products. Wound irrigation is all we do. That's why we do it best! And now, we do it even better! It's even faster than the original ZEROWET SPLASHIELD because it stays on the syringe all the time. You never have to take it off! And, it costs no more! If you're old enough, you might remember using needles or IV catheters to provide the optimal 8-12 psi pressure required to effectively irrigate wounds. Of course, the everpresent splash, and the occasional needlestick were real problems. The introduction of the original ZEROWET SPLASHIELD in 1990 completely eliminated both problems. That's why it quickly became standard irrigation equipment in most ED's in the US, and is still recommended by name in many leading emergency medicine texts and articles. (And in case you didn't know, the literature warns us that other methods, such as soaking, bulb syringes, or squeezing plastic bottles are all low-pressure techniques that are simply not effective!)
