Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1-2, the leakage-proof catheter of the present utility model includes a main body 1, one end of the main body 1 is inserted into a bladder, the other end is externally connected with urine, the portion of the main body 1 extending into the bladder is a head 1a, the head 1a is hemispherical, a plurality of through holes 1c are formed in the head 1a, and the urine is led out through the through holes 1 c.

A relatively thin branch pipe body 2 is inserted into the main pipe body 1, an expansion bag 3 is connected to the main pipe body 1 in a matching way, the expansion bag 3 comprises a main bag 31, a rod bag 32 and a side bag 33, wherein the main bag 31 is arranged below a head 1a of the main pipe body 1, and the branch pipe body 2 extends below the head 1a of the main pipe body 1 in the main pipe body 1 and penetrates through the outer wall of the main pipe body 1 to be communicated with the main bag 31. The rod bags 32 are provided with a plurality of rod bags 31 which are uniformly distributed in the circumferential direction, and side bags 33 are arranged between the end parts of the rod bags 32, and the interiors of all the

rod bags
