2.2, drainage catheter 2.1 is connected with urination hole 5 and hollow out loose structure 3, and balloon catheter 2.2 is connected with anticreep air bag 1.It is described
Loose structure 3 also helps the drainage of mucous membrane of urethra secretion while drainage of urine, can reduce urethral catheterization complication or urethral catheterization
The generation of pipe indwelling related complication.
The shape of the loose structure on the hollow out porous type urethral catheterization tube wall can be existing known any shape, actual
In can, urinary catheter in time difference different according to catheter model and change, realize individuation urethral catheterization.
The cross sectional shape of the parallel catheter major axis of hollow out loose structure 3 may be designed to interior big outer small or inner small and outside big
It is trapezoidal, or inside and outside equal rectangle.(as shown in Figure 2), the construction energy when cross sectional shape is interior big outer small trapezoidal
Duct of the derived urine in hollow out loose structure 3 is avoided to gather, urethral catheterization is more thorough, reduces the hair of catheter Infective morbidity
Raw rate.
Improvement project：The urethral catheterization pipe outer wall is circle, and the groove structure of parallel catheter long axis direction is added in outer wall,
Groove structure reduces the contact area of urethral catheterization tube wall and mucous membrane of urethra, further reduces self retaining catheter to mucous membrane of urethra
The change of microenvironment, reduce that mucous membrane of urethra is subject in self retaining catheter damages, while the duct in hollow out loose structure 3
