[0020] Among them, by inserting the catheter body 1 into the urethra, and then inserting the infusion needle into the diaphragm 203 in the plug connector 202, and the infusion hose of the infusion needle is clamped in the inside of the clamping groove 204, the infusion hose is limited by the clamping block 205, and the position of the infusion needle in the plug connector 202 is fixed. Then, the physiological saline inside the infusion needle will enter the catheter 206 through the infusion tube 201, and then flow into the bladder through the countercurrent tube 207. The above structure can prevent the doctor from puncturing the catheter and injuring the finger when inserting the infusion needle, which protects the health of medical staff.

[0021] Preferably, the catheter tube 206 is connected to the infusion tube 201 , and the catheter tube 206 is in contact with the inner wall of the urinary catheter body 1 .

[0022] The arrangement of the catheter 206 can prevent the physiological saline solution and the urinary catheter body 1 from sharing a common pipeline, thereby preventing the physiological saline solution from being contaminated and preventing the physiological saline solution from conflicting with the urine in the urinary catheter body 1 when circulating.

[0023] Preferably, a gas adding tube 103 is fixedly connected to one side of the fixed tube 2, an air guide tube 102 is fixedly connected to the inner wall of the catheter body 1, the air guide tube 102 and the gas adding tube 103 are connected, and an air bag 101 is fixedly connected to the outer wall of the catheter body 1, the air bag 101 and the air guide tube 102 are connected.

The diaphragm 203 provided therein is made of silicone material, and the infusion needle can be inserted into the diaphragm 203 to fix the position of the infusion needle needle head. The above structure can prevent the doctor from puncturing the catheter and causing finger injuries when inserting the infusion needle, which protects the health of medical staff. Then, the physiological saline inside the infusion needle will enter the catheter 206 through the infusion tube 201, and then flow into the bladder through the reverse flow tube 207, completing the step of cleaning the bladder with physiological saline, wherein the catheter groove 2 10 is provided with a first groove 211, a second groove 212 and an obstruction block 213. This structure can be used to obstruct the urine in the bladder from the liquid outlet 209 into the liquid guiding groove 210 by the first groove 211, the second groove 212 and the obstruction block 213, so that it is difficult for the urine to flow into the liquid guiding groove 210. When the physiological saline enters the liquid guiding groove 210 from the infusion port 208, the physiological saline will pass along the edges of the obstruction block 213 and the first groove 211 and the second groove 212 through the design of the obstruction block 213 and the first groove 211 and the second groove 212, which can play a role in guiding the physiological saline, thereby facilitating the circulation of the physiological saline, so that the bladder can be better cleaned by the physiological saline, and the probability of the physiological saline being contaminated by urine is reduced.
