Background
A urinary catheter is a medical device that is inserted into the urinary bladder from the urethra to direct urine out. The three-cavity urinary catheter is a common urinary catheter and comprises a urinary catheter main body, an air bag, a main joint, a flushing joint and an air bag joint, wherein the urinary catheter main body is provided with a main pipe hole and a flushing hole which are arranged along the length direction of the urinary catheter main body, the main joint is connected with the rear end of the urinary catheter main body and communicated with the main pipe hole, the flushing joint is connected with the rear end of the urinary catheter main body and communicated with the flushing hole, and the air bag joint is connected with the rear end of the urinary catheter main body and communicated with the air bag. When the urinary catheter is used, the urinary catheter is inserted into the urinary bladder from the urethra, the air bag is positioned in the urinary bladder, and water or air is injected into the air bag through the air bag connector to make the air bag clap so as to prevent the urinary catheter from falling off. The main joint is connected with the urine bag, and urine is led out from the main pipe hole and the main joint and enters the urine bag for collection.
Bladder irrigation is a method of removing foreign substances such as blood clots, mucus, bacteria, etc. from the bladder. Bladder irrigation was performed by a catheter-fitted irrigator.

The irrigator may also be a syringe or the like, which can be used to inject fluid into the bladder for pressurized irrigation.
The blockage of the urinary tract is a common problem in the urinary tract indwelling process, and fluid is often encountered in the bladder irrigation process because the main tube hole is blocked by blood clots or other intravesical sediments. After the catheter is blocked, the catheter is required to be dredged, a 20mL syringe can be used for extracting normal saline, and then the normal saline is injected into the main pipe hole through the main joint in a pushing mode so as to break up or flush an object blocking the main pipe hole, and the dredging of the catheter can be repeated for a plurality of times.
