  • Patent number: 10285846
    Abstract: Disclosed herein is a urethral catheter with an anti-infection structure for infants in which, in a state in which a hose is combined with a main pipe in advance, the reinforcement rod is inserted into/released from a urethral insertion pipe through a reinforcement rod inflow and outflow pipe separately formed at one side of the main pipe to prevent leakage of urine. When the reinforcement rod is inserted into the urethral insertion pipe in the combined state of the hose with the urethral insertion pipe and is then released from the urethral insertion pipe, setting of a urine storage bag is completed, thereby shortening a time to install of the urine storage bag, reducing medical staff's trouble, and preventing contamination and infection of a patient and the medical staff due to leakage of urine from the bag to the outside.
