Adopt the catheter of this kind of structure, urine and flush fluid outflow in the bladder are avoided in the design of pipe shaft, urine and flush fluid are along the escape orifice, discharge to the urine bag in from excreting the kneck through the escape cavity, pipe shaft outer wall trough of belt design can make in the urethra a small amount of secretion along the groove discharge external, avoid the inflammation that urine retention arouses, simultaneously because of the catheter is made by the silica gel material, itself has good biocompatibility, trough of belt design has reduced pipe shaft and urethra area of contact, anti-infectious purpose has been reached, because the pipe shaft has adopted integrated into one piece technology, the pipe adopts the changeover portion design with trough of belt pipe intersection, its appearance is level and smooth and whole pipe shaft external diameter size is even, the insertion process is little to the urethra damage, tensile strength is big, the cracked condition of pipe shaft can not take place for the use, the safety of use has been ensured. The catheter body is also provided with a developing line, and the inserting position and the depth of the catheter are determined by the developing line when the catheter is used; the whole catheter is made of medical silica gel, so that the biocompatibility is good, the sensitization reaction is avoided, and the material is safe;

the one-way valve is arranged on the inflation interface, so that after the catheter body is inserted into the bladder for a certain distance, the balloon completely enters the bladder, a few round tubes and the grooved tube are positioned in the urethra at the moment, the syringe without a needle head is inserted into the one-way valve, rated sterile gas or sterile water is injected, the bladder is clamped by the expanded balloon, the syringe is pulled out, the one-way valve is closed, the balloon is kept expanded, one end of the catheter plug can be kept in the bladder, the length of the catheter body between the plug and the balloon is set according to the size of the bladder of a normal person, the inventor does not need to repeat here, and when the catheter needs to be pulled out, the gas or the sterile water in the balloon is pumped out by the syringe to reduce the balloon to the original size.

In conclusion, the catheter adopting the structure is simple and reasonable in structure and convenient to operate and use, urine and flushing fluid in the bladder are prevented from flowing outwards through the circular tube, a small amount of secretion in the urethra can be discharged out of the body through the groove design of the outer wall of the tube body, inflammation caused by urine retention is avoided, meanwhile, the contact area between the tube body and the urethra can be reduced, the purpose of resisting infection is achieved, the catheter and the catheter are in transition connection, operation of medical workers is facilitated, and pain of patients is relieved.
