AV Fistula Needles With MasterGuard®

Anti-stick needle protector

masterguard from medisystems

"MasterGuard... gives the nurse/technician the benefit of cannulating the patient with a 'regular' needle, with a needle protection system that stays out of the way of the user and patient. It's there, but functionally, it's out of the way until it's needed. That's why I've been using them ever since Medisystems created them."

-Joe Atkins, RN, MBA, CNN, CHT, with 36 years of hands-on experience as a dialysis technician, as well as Nephrology Nurse (read Joe's entire letter to Medisystems here)
