Directions for Use:Wash your hands and open the pouch containing KONIX Sterile Water. Before use, visually inspect each pre-filled syringe for clarity, discoloration, or leakage. Do not use the syringe if any of these issues are observed. Remove the syringe cap, hold the syringe with the tip facing upward, and gently press the plunger to expel any air. Attach the syringe tip to the inflation lumen of the Foley catheter. Inflate the Foley catheter balloon using the correct volume.
