Nexus TKO®-5 is the only Anti-Reflux technology which utilizes a Blunt Plastic Cannula. Nexus TKO®-5 provides Blood Reflux Protection 24/7!™  for all Peripheral, PICC and CVC Catheters while delivering a safe and effective microbial barrier.  TKO®-5 offers your patients a new level of safety and protection against unwanted catheter occlusions.      
Nexus TKO®-5 Anti-Reflux Technology Overview
Catheter occlusions are difficult to avoid and create unwanted complications 25% of all central venous catheter (CVC) develop partial or full occlusions3,4 Blood can inadvertently reflux into a catheter in multiple ways Current needle free injection sites do not effectively address the many causes of blood reflux Blood reflux may lead to several unintended IV complications, including the following: - occlusions - infiltrations - phlebitis - costly catheter restarts - catheter-related bloodstream infections (CRBSIs) Blood reflux is the main cause of occluded catheters Occlusions  may result in delayed therapy, 13 Occlusions increases the risk of CRBSI’s, 1,2,3,4,17,18 Occlusions created the need for catheter replacement or exchange, 13 Occlusions prevent blood sample from CVC/PICC catheter  When blood refluxes into a catheter there is the potential for the Clinician to force the syringe plunger forward when flushing and damage the intima of the vein wall, which may end in a complication resembling an IV infiltration10 Clotted Catheters are known contributors to catheter-related bloodstream infections (CRBSIs)1,2,3,4, 87% percentage of all bloodstream infections involve some type of IV device21 Catheter occlusions  lead to catheter replacement, increased risk of complications, added patient stress and risk of infection13 CRBSIs are the most costly and life threatening of all healthcare-acquired infections13 CRBSIs cost up to $35,000 per episode, with more than 250,000-500,000 episodes per year in the US13 “Centers for Medicare and Medicaid Services (CMS) no longer reimburse hospitals for vascular catheter- associated infections (initiated October 2008)”20
How The Nexus TKO®-5 Anti-Reflux Diaphragm Works
Nexus TKO®-5 Anti-Reflux Technology Provides Blood Reflux Protection 24/7!™ The Nexus TKO®-5 Anti-Reflux diaphragm automatically opens and closes based upon fluid pressure.  The TKO diaphragm open towards the patient with fluid pressure from sources such as IV pump, syringe pump, IV bag, flushing or medication syringe are used.  When the fluid pressure drops the TKO diaphragm instantly and automatically closes preventing blood reflux into the catheters.  
No clamping sequence required: The Nexus TKO® Anti-Reflux technology requires  NO CHANGE in practice or clamping sequence, the device automatically provides                        Blood Reflux Protection 24/7!™
Our patented Tri-Seal™ design with Slit-Lock™ technology is designed into all of our Needle free devices. The Nexus TKO® Tri-Seal™ design provides Microbial Barrier Protection 24/7!™   The Nexus TKO®-5 Tri-Seal™ design with Slit-Lock™  technology has been validated with 3-separate bacteria (S. aureus, S. epidermis and E. coli) by an outside GLP laboratory using a 96- activation protocol with non-locking cannula     
First Level of Protection:                          Second Level of Protection:           Third Level of Protection:
A 360° compressed seal proven to provide a safe and effective microbial barrier protection between the septum and the needle-free connector housing
A smooth, easy to disinfect septum surface, promotes a safe and effective microbial barrier.
The Slit-Lock™ septum protects the internal fluid path from microbial ingress while luer is activating
“Theoretically, Blood Reflux into either the IV catheter or the needleless connector increases both the risk of occlusion and biofilm formation.” William R. Jarvis MD
