Needle-Free Access Devices


The nPulse Valve Platform of needle-free connectors for infusion therapy is designed to compliment best clinical practices to reduce the risk of catheter-related bloodstream infections (CRBSI), and reflux-induced catheter occlusions. 1-5


  • Neutral fluid displacement at both Luer connection or disconnection helps reduce reflux-related occlusions
  • Self-opening split septum (SOSS) protects septum plane from  abrasion unlike spike platforms.


  • Dual seal design intended to defend against microbial ingress and provide redundant leak protection in critical arterial and high pressure applications.2


  • Designed to complement best clinical practices and does not  require clinician clamping to control valve-induced reflux.4
  • Ergonomically designed to balance usability and size in clinical applications where smaller is better.


  • Solvent-free, permanently ultrasonically welded assembly to assure structural integrity of product and fluid containment.


  • Offered in multiple configurations to meet various clinical needs.


  • Sterile packaging available (e.g. blister packs and pouches).
