[0002] A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] Catheters are generally divided into 13 specifications from 6F to 30F according to the circumference of the outer diameter. Commonly used adult catheters are 12F, 14F, 16F, and 18F. Catheters include ordinary catheters for disposable non-indwelling catheterization, fungiform catheters for suprapubic cystostomy and cecum fistula, pointed catheters for prostate hypertrophy, and balloon catheters commonly used in clinical practice.

[0004] In medical care, some patients need to use a urinary catheter for a long time, which increases the chance of urinary tract infection. The commonly used method is to infuse the drug into the bladder through the catheter without removing the catheter, and then drain it to achieve the purpose of flushing and treatment.

[0005] In order to achieve the flushing function, the existing urinary catheter generally has two pipelines arranged inside the tube, and two joints connecting the two pipelines are arranged at the end of the urinary catheter. When in use, one joint is connected to the urine bag, and the other joint is connected to the flushing device. The cleaning liquid is injected into the urinary catheter through one joint and the pipeline, and then flows back to the urine bag through the other joint and the pipeline to achieve cleaning. However, the above-mentioned urinary catheter has the following problems:

[0006] 1. Both connectors are connected to the human body through pipes, and air can enter the human body through the pipes, increasing the chance of infection and having low safety performance;

[0007] 2. When no flushing is performed, urine will flow out through two pipes. Part of the urine will be transported to the urine bag for storage through one of the pipes, and the other part of the urine will be stored in the other pipe. Long-term storage is prone to breed bacteria and clog the catheter. Summary of the invention
