AI Technical Summary
Existing urinary catheters experience backflow of medication and water during filling with water or flushing with medication. Furthermore, medication can easily remain at the filling and flushing ends when the patient urinates, leading to problems such as urine leakage and difficulty in dislodgement.
A leak-proof flushing catheter is designed, which uses water injection pipes and flushing pipes set on the left and right sides. The inner sides of the water injection pipe and the flushing pipe are respectively fixedly connected to the first and second one-way valves. The end of the drug injection rigid tube has a sealing plug, and the connecting pipe has a water injection rigid valve. The front end of the main body has a fixed balloon and a urine catheter head. The urine catheter head has a urination hole. The one-way valves prevent the backflow of drug solution and water, so as to achieve effective flushing and urination.
It effectively prevents the backflow of medication and water, ensures smooth urine excretion, avoids urinary leakage, and achieves effective bladder flushing and urine collection.

After being inserted into the bladder, water is injected into the fixed balloon through the connecting tube and the water injection tube, and the main body is pulled back to make the fixed balloon close to the internal urethral opening, so that urine leakage can be avoided and the fixed balloon is not easy to fall off, so that the urine discharged by the patient can flow into the main body through the urinary hole and be discharged into the urine bag through the urinary tube. When water is injected through the connecting tube and the water injection tube, the first one-way valve provided in the water injection tube can avoid the phenomenon of water backflow. When it is necessary to flush the patient's bladder, the sealing plug is removed from the medicine injection hard tube. After removal, the medicine liquid is injected through the medicine injection hard tube and the flushing tube. At this time, the second one-way valve provided can avoid the phenomenon of medicine liquid backflow, thereby realizing the flushing of the patient's bladder, and the sewage after flushing is discharged through the urinary tube.
