About Product

Bionector TKO® is a patented “To Keep Open” valve, with 100% bi-directional fluid control and a straight fluid pathway. Bionector TKO has been specifically designed to reduce catheter occlusion, and works by controlling the bi-directional flow of fluid, infusate and catheter tip blood reflux.

Occlusions can be commonplace in patients with vascular access lines, which both costs you money and affects your patients.This is accepted as normal, with occlusions and their consequences being dealt with as a matter of routine.The most common are: thrombotic occlusion when blood or clotting agents accumulate inside the catheter and persistent withdrawal occlusion when fibrin is aspirated into the catheter.

This is where Bionector TKO can benefit you, it is clinically shown to reduce; catheter occlusions by 88% (50.4 to 5.8 per 1,000 catheter days)*, loss of IV catheter by 91% (9% to 0.8%)* and tissue plasminogen activator (tPA) usage by 85%*.

Bill Scroggs, Senior ODP and Midline/IV Access Team Leader, Burton Hospitals NHS Trust after implementation of Bionector TKO on Midline catheters

"We really wanted to help as many people as possible get back home to receive their treatment rather than sitting in a hospital bed. TKO has helped us achieve that and, at the same time we’ve brought down the blockage rate, we have increased the number of lines inserted. Dwell time has also gone up from an average of five days to between eight and nine. Also, as an exception we keep the lines in for longer and we have extended our maximum dwell time too to 53 days."

Clinical Nurse Specialist (CNS) Sue Rowlands, from the IV Resource Team at the Royal Wolverhampton NHS Trust.

"We’re really pleased with what the team is achieving with Bionector TKO and patients see the benefits because the reduced number of line occlusions means that drugs are administered in a more timely fashion, and patients don’t have the distress of having repeated line insertions. We are also saving valuable clinical time by not having to unblock lines or re-insertion of catheters. Royal Wolverhampton NHS Trust has transformed the insertion and care of IV lines to deliver a better experience for patients as well as helping the Trust save money"
