Catheter-related bloodstream infections (CRBSI) challenge all healthcare professionals            today and have significant impact on both clinical and financial resources. The connection            between thrombosis and infection is well documented and identifies significant colonization            rates in areas of clot formations and its linkage to higher rates of catheter-related sepsis            and catheter related septicemia when thrombosis is present 1,2,3,4,5,6      
CRBSI’s challenges all health care professionals today
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 device17 Catheter occlusions  lead to catheter replacement, increased risk of complications, added patient stress and risk of infection14 CRBSIs are the most costly and life threatening of all healthcare acquired infections14 CRBSIs cost up to $35,000 per episode, with more than 250,000 episodes per year in the US6 “Centers for Medicare and Medicaid Services (CMS) no longer reimburse hospitals for vascular catheter-associated infections (initiated October 2008)”7
Nexus TKO® Tri-Seal™ design provides Microbial Barrier Protection 24/7!™ Our patented Tri-seal™ Design with Slit Lock™ technology is designed into all of our Needle free technologies (NIS-5, NIS-6, NIS-6P, TKO-5, TKO-6 and TKO-6P).  The Nexus TKO® Tri-Seal™ Design provides Microbial Barrier Protection 24/7™.   The Tri-Seal™ design with Slit Lock™ technology has been validated using 4-separate study groups with 4-separate bacteria (S. aureus, S. epidermis, E. coli, and P. aeruginosa) by an outside GLP laboratory using a 96-activation protocol over the course of 4 days.  
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

How The Nexus TKO®-6 Anti-Reflux Diaphragm Works
Nexus TKO®-6 Anti-Reflux Technology Provides Blood Reflux Protection 24/7!™ The Nexus TKO®-6 Anti-Reflux diaphragm automatically opens and closes based upon fluid pressure.  The TKO diaphragm open towards the patient when 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 prevention 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!
