The catheter is made of soft materials, is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride, and can be inserted into the bladder through the urethra so as to drain urine; two factors need to be considered in the using process of the catheter, namely, how to smoothly guide the catheter into the bladder; another factor is that after the catheter is inserted into the bladder, during the catheterization process, it is necessary to ensure that the end of the catheter for catheterization can be left in the bladder without falling off, so that smooth catheterization is achieved.
In the prior art, in order to ensure the smooth introduction of the catheter, the following technical means are basically adopted: the end part of one end of the catheter is provided with a bullet-shaped structure, the overall outer diameter of the bullet-shaped structure is smaller than the outer diameter of the catheter, and then the guiding in the implantation process is realized, but after the catheter enters the bladder, the bullet-shaped structure is continuously rubbed with the inner wall of the bladder, so that the problem of damage to the inner wall of the bladder is easily caused.
In order to ensure that one end of the catheter for catheterization can be left in the bladder without falling off, a balloon is arranged near the head end of the catheter, after the catheter is placed in the bladder, the balloon is filled through an external connecting pipeline, and the filled and enlarged balloon realizes that the catheter is fixed and left in the bladder and is not easy to fall off; in the prior art, in order to avoid damage to the bladder inner wall caused by the bullet-shaped structural tip, the mode of wrapping the end part after the balloon is filled is adopted for avoiding. However, this approach has the following problems: firstly, because the space in the bladder is limited, the balloon occupies a large space after being filled, which is not beneficial to the storage of urine; secondly, the protrusion of the top end of the saccule causes continuous physical stimulation to cause iatrogenic injuries such as bleeding, pain, inflammatory reaction, polyp, bladder spasm and the like, and causes additional injuries to patients. The traditional catheter has no saccule design, reduces iatrogenic injuries such as stimulation to the bladder, bladder spasm and the like, but lacks the function of falling prevention; thirdly, the balloon is required to be provided with a channel communicated with the balloon on the side wall of the catheter which is thin in the filling process, and meanwhile, the balloon is required to be only attached to the side wall of the catheter in the unused process, so that the requirements on processing precision are high, and the processing is inconvenient and the cost is high.

Meanwhile, the diameter of the built-in tube 2 is smaller than that of the traditional catheter when the urethra is narrow, so that the catheter can pass through, and the urine discharge can be ensured due to the fact that the catheter is structurally provided with the urine discharge hole 204. For patients with urethral obstruction caused by prostatic hypertrophy, space occupying lesions and other reasons, the traditional catheter balloon is too large to ensure the stimulation effect on the bladder, and the urethra and the urethral obstruction part are easy to be damaged in the urethral catheterization process.
For young and young patients, the body is not developed completely, the urethra is narrower than that of adults, and the catheter guiding and placing can increase the placing success rate and reduce the risk of urethral laceration.
