The present invention relates to a catheter of infection protective structure for insertion into the urethra. The purpose of the present invention is to provide a catheter of infection protective structure for insertion into the urethra, in which a reinforcement bar is inserted and drawn out through a separate reinforcement bar entrance tube formed at one side of a main tube in a state where a hose is coupled to the main tube so as to prevent contamination that may occur due to the hose being coupled and decoupled at the same position as the position where the reinforcement bar is inserted and drawn out, thereby preventing any undesired leakage of urine at the time of coupling the hose to the main tube. If the present invention is employed, the setting of a storage pouch can be completed by inserting the reinforcement bar into the urethral cannula and drawing out the reinforcement bar in a state where the hose is coupled to the urethral cannula. Accordingly, there are advantages in that the installation time of the storage pouch can be shortened, thereby reducing the efforts by a doctor, and that any undesired leakage of urine to the outside other than the urine storage pouch can be prevented, thereby preventing a doctor from being contaminated and infection accidents.La présente invention concerne un cathéter ayant une structure protégeant contre les infections et destiné à être inséré dans un urètre. La présente invention vise à fournir un cathéter ayant une structure protégeant contre les infections et destiné à être inséré dans un urètre, dans lequel une barre de renforcement est insérée et retirée par un tube dentrée de barre de renforcement distinct formé au niveau dun côté dun tube principal dans un état dans lequel un tuyau est couplé au tube principal pour empêcher la contamination qui peut intervenir en raison du fait que le tuyau est raccordé et séparé à la même position que la position à laquelle la barre de renforcement est insérée et retirée, empêchant
