• an occlusion cap is placed at the tip of the branch tube. If urine and pus are prevented from flowing out of the branch tube by wearing a urine or pus, the urine or pus is led out of the catheter via the catheter connection section and the catheter extension tube into the liquid storage bag, where it is stored.
• the bladder can be cleaned by removing the obstruction cap attached to the end of the branch tube and connecting the branch tube to a cleaning tool or a drug injector.
• the catheter extension tube of the present invention when cleaning the bladder or the like, by connecting the cleaning tool or the drug injector to the branch tube without disconnecting the catheter from the catheter connection portion, the cleaning liquid or the like can be obtained. Drugs can be injected. As a result, bacterial infection of the catheter caused by removing the catheter and the catheter connection portion can be reliably prevented, and the complicated work of replacing the catheter with the catheter extension tube is eliminated. can do.
• the backflow to the branch tube that occurs when the bladder or the like is washed as described above can be dealt with by pressing the flexible branch tube with a pressing member such as forceps or the like. It is hard to get in the way if you place a tube at the base of the catheter connection and shorten the branch tube.

• a branch tube 6 is connected to the other branch port of the branch tube 5.
• the branch tube 5 is connected to the base of a nipple 7 that is a connection portion with the catheter 11, the nipple 7 and the branch tube 6. At the same time, it is integrally formed of vinyl chloride. Thus, the branch tube 6 has flexibility. Further, a screw-in type closing cap 8 is provided at an open end of the branch tube 6, and an air filter 9 is provided at one upper corner of the urine storage bag 1. J
• the urinary canal 1 is also very flexible, and the urinary canal 1 is provided with a pressing member 10 so that the urinary canal 1 can be appropriately closed by the pressing member 10. It is. ,
• the urinary tract 1 formed in this way is connected to the nipple 7 with a catheter 11 for exclusive use for indwelling, such as a Foley-balloon catheter, a malecot catheter, etc. If the urine is accumulated in the bladder by applying abdominal pressure, the urine accumulated in the bladder can be led out into the urine bag 2.
