Our story

The founder of Nistaa, Inc. is a Registered Nurse.  The agonizing frustration of dealing with the perpetual dilemma of keeping patients PICC lines and peripheral IV lines dry while they bathed or showered was the catalyst for the invention of the Nistaa® waterproof transparent barrier. Many nurses will testify that plastic bags and other plastic products secured with tape are ineffective methods for keeping site areas dry. Finally, health care clinicians, patients, and family members will no longer have to rely on ineffective methods. The Nistaa® waterproof transparent barrier is the solution.


Our product

Nistaa® waterproof transparent barrier maybe used to completely cover and protect central venous devices(e.g. a PICC line or a Port-A-Cath), hemodialysis catheters, peripheral IV lines, surgical incisions and wound dressings from water while a patient bathes or showers.


Materials used

Nistaa® is latex free and consists of a medical grade hypoallergenic adhesive film and a medical grade adhesive free film. Nistaa® is thin, flexible and conformable. The unique design provides a double layer of protection against water while enhancing patient comfort.

"Your cover worked for my port when no other one did."


"I've tried every waterproof dressing on the market for keeping my port dry while showering and yours is by FAR the best out there. This product saves me 10 minutes every morning that I'd otherwise spend fighting with various dressings and tape that still manage to leak.”


"I just LOVE the Nistaa Barrier! I have showered vigorously with it, and even taken a bath and had my arm underwater for some time, I have not gotten a drop wet inside. I am just in AWE over your product! AND it is SO much easier to attach too! Just a minute and I am in the shower, not 10-15 minutes of hassle.  This is just so so so much better. I LOVE IT?"


As a new to market "Waterproof Transparent Barrier," this is by far the best water barrier/shower sleeve that is out there. This PICC line protector for showering allows for flexibility of the arm, without worrying about constricting the blood flow, that some other shower sleeves on the market may cause. The Nistaa feels like a larger Tegaderm dressing going over our other dressing. Check them out?"
