Abstract

Abstract A device for use as a single use, disposable, sterile irrigation kit for catheter irrigation, comprising a prefilled sterile piston syringe containing from about 45 to about 75 cc of a fluid selected from sterile water, saline solution and dilute aqueous acetic acid solutions, said syringe including a catheter tip sized to operably connect to a conventional catheter tube, a cap on said tip removably mounted to selectively prevent escape of said fluid from said syringe and prevent movement of said piston while said cap is on said tip, said kit further including a disposable pouch for enclosing said filled syringe, said pouch and said filled syringe being sterilized after enclosure of said syringe in said pouch, said device further including a container having a tear-off top labeled with the specific solution in said syringe and a color code system marking at least a portion of said device with a color identifying the particular solution, said container enclosing said pouch containing said filled syringe and further including sterilized gloves and an applicator pad.
