[0023] Working principle: the balloon 2 of catheter body 1 end is placed in the inside of patient's bladder, when inflating balloon 2, as follows:

[0024] Needle is inserted into the inside of piercing hole 435, push piston, so that gas impact on the surface of sealing seat 444, so that sealing seat 444 overcomes the elastic force of spring 445, so that sealing seat 444 is separated from sealing block 441, so that gas enters the inside of balloon 2 through catheter body 1, inflates balloon 2 and works;

[0025] When needle is pulled out, at this time, under the reset rebound work of spring 445, sealing seat 444 restores to initial state, and sealing block 441 is blocked;

[0026] At the same time, when the needle is pulled out from the inside of the puncture hole 435, the rubber plug 434 extrudes the puncture hole 435; the gas inside the balloon 2 can be prevented from leaking, so as to avoid the catheter body 1 from falling off due to the leakage of the balloon 2.

[0027] As a preferred embodiment, the limiting sheet 431 is made of plastic material and has a "concave" cross-section, and the limiting groove 432 is arranged on the surface of the limiting sheet 431, and the positioning hole 433 is arranged in the middle of the limiting groove 432.

[0028] The positioning hole 433 is arranged opposite to the puncture hole 435, and the cross-section of the positioning hole 433 is arranged as an isosceles trapezoid.

[0029] As shown in Figures 1-4 : the arrangement of the positioning hole 433 and the limiting groove 432 allows the sharp needle to be quickly inserted into the inside of the puncture hole 435 through the positioning hole 433, so that the gas sprayed from the needle impacts on the sealing seat 444 to overcome the elastic force of the spring 445, thereby realizing the gas injection of the balloon 2.

[0030] As a preferred embodiment, the limiting plate 436 is fixedly installed on the inner wall of the pipe body 42, and the limiting plate 436 and the rubber plug 434 have a concentric circular structure, and the end of the rubber plug 434 is fixedly arranged on the surface of the limiting plate 436.

[0031] One end of the flow hole 443 is provided with the air inlet hole 442, and the cross-section of the air inlet hole 442 is arranged as an arc, and the flow hole 443 is sealed by the sealing seat 444.

[0032] When the gas is no longer sprayed on the outer surface of the sealing seat 444, the flow hole 443 is sealed by the sealing seat 444; so that the gas inside the air bag will not leak.

[0033] As a preferred embodiment, the sealing seat 444 is made of rubber material and has a semispherical structure, and the installation groove is arranged in the inside of the sealing seat 444, the end of the guide rod 446 is fixedly connected with the installation groove, the spring 445 is wrapped outside the guide rod 446, the guide rod 446 is inserted into the guide hole arranged in the guide seat 447, and the end of the guide seat 447 is fixedly connected with the inner wall of the pipe body 42.
