Nipro’s Biohole Safetouch Tulip AVF needles are intended for the buttonhole technique, with the added protection of a nonreversible safety mechanism.
With the possibility of one-handed activation, this blunt AVF needle is designed to reduce the risk of needle stick injuries (NSI) while ensuring a less painful puncture – Offering you the benefits of the buttonhole technique with a safe option for all. 

  • Siliconized dull needle reduces pain compared to the rope-ladder technique1-5
  • Minimizes potential needling error and hematoma formation 4, 6, 7
  • Less AVF complications: reduces aneurysm formation and only two puncture sites required 4
  • Decreases bleeding time 8-10 
  • Reduced risk of needle stick injuries thanks to a nonreversible mechanism
  • Active Tulip safety feature using a one-handed technique
  • Unique locking mechanism confirmed by tactile “click”
  • Ultra-thin wall for optimal blood flow 
  • Textured, turnable of fixed, color-coded wings
  • Color-coded occlusion clamp and tapered luer
  • Includes scab remover
  • Latex-free, DEHP-free
  • Gamma sterilization
