The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 3, a urinary catheter according to an embodiment of the present invention includes: a conical air bag 1 after being inflated or injected with water; an air bag tube 2 fixedly connected with the air bag 1 and used for inflating or injecting water into the air bag 1; the catheter body 3 is arranged in the air bag tube 2 and the air bag in a penetrating way.

The above embodiment of the utility model, after aerifing or the water injection in to gasbag 1 through gasbag pipe 2, gasbag 1 is conical, fixes the catheter, because gasbag 1 is more and more thin towards the one end of urethral orifice, so change the laminating with patient's urethral orifice, can not make the urine that does not get into the catheter flow from the urethral orifice, brought a lot of facilities to patient's treatment and nursing, also reduced patient's misery simultaneously.

In one embodiment, the end of the catheter body 3 for receiving urine is provided with a urine guide hole. The urethral catheterization hole is a round hole, and the diameter of the round hole is 3 Fr-5 Fr. As shown in fig. 3, the urethral catheterization hole includes: a first urethral catheterization hole 4, a second urethral catheterization hole 5 and a third urethral catheterization hole 6; the first urethral catheter hole 4 is arranged at the top end of the urethral catheter body 3 for receiving urine; the second urethral catheterization hole 5 and the third urethral catheterization hole 6 are arranged on two side edges of the urethral catheter body 3 for receiving urine in a relative staggered manner, so that the urethral catheterization capability of the urethral catheterization holes is improved, and the possibility of tube blockage is reduced.

Specifically, the longitudinal section of one end of the catheter body 3 provided with the urethral catheterization hole is similar to a U shape, the first urethral catheterization hole 4 is arranged on the protruding part of the U shape, and the second urethral catheterization hole 5 and the third urethral catheterization hole 6 are arranged on two sides of the U shape.

The position design of first catheterization hole 4, second catheterization hole 5 and third catheterization hole 6 more accords with the catheterization demand, can make the urine in the bladder all get into catheter body 3, when the patient produced urine speed at the excessive speed, can not be because the catheterization hole is few and stay the bladder with partial urine.

The cross section of catheter body 3 and gasbag pipe 2 is circular, and circular shape design not only makes the utility model provides a catheter inserts patient's bladder more easily in, also more smooth and easy to the discharge of urine.

In an embodiment, the end of the catheter body 3 for draining urine is provided with a urine outlet 7. The urine in the catheter body 3 is discharged through the urine outlet 7.

In one embodiment, the balloon tube 2 is provided with a balloon inflation port 8 for receiving external gas or water. When the catheter provided by the utility model is inserted into the bladder of a patient, the air bag is filled with gas or water through the air bag inflation inlet 8 and the air bag tube 2. The range of the inflating quantity or the water injection quantity of the air bag is 4ml to 30ml according to the type of the catheter, and the larger the type of the catheter is, the larger the volume of the catheter is.

In one embodiment, the material of the ureter body, the air bag and the air bag tube 2 is silicon rubber. The silicon rubber is softer, has no stimulation and better compatibility, and does not harm patients.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
