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. Blood reflux is a key cause of catheter occlusion which can lead to the inability to withdraw blood or infuse medications. Bionector TKO® is an easy to use, innovative product from Vygon Vet, which is designed and proven to help greatly reduce catheter occlusions.
