An antibacterial urinary catheter comprises a main body and an antibacterial carbon material. The main body is provided with a urine drainage passage, and the antibacterial carbon material is disposed within the urine drainage passage. The BET surface area of the antibacterial carbon material is between 500 and 1800 m2/g, and the volume of micro holes with diameters smaller than 2 nanometer in the antibacterial carbon material is about 30 to 50% of the total volume of holes. By configuring antibacterial carbon material having antibacterial function within the urine drainage passage of urinary catheter, the bacteria outside the human body cannot enter the bladder and the bacterial inside the bladder may also be killed, therefore, the invention effectively prevents the urinary system from bacterial infection.一種抗菌導尿管,包含一本體以及一抗菌碳材,該本體內具有一導尿通道,該抗菌碳材設於該導尿通道內。該抗菌碳材之BET比表面積介於500m2/g與1800m2/g之間,且該抗菌碳材中孔徑小於2奈米之微孔容積佔總孔洞之容積比例介於30%與50%之間。藉由在導尿管的導尿通道內設置具有抗菌功能的抗菌碳材,使得人體外部的細菌無法進入膀胱,同時位於膀胱內的細菌亦可被消除,可有效預防泌尿系統之細菌感染。1‧‧‧本體11‧‧‧導入口12‧‧‧導尿通道13‧‧‧引流通道14‧‧‧導出口15‧‧‧注射口2‧‧‧抗菌碳材21‧‧‧抗菌通道3‧‧‧球囊
