Abstract

The invention discloses a fistulization catheter which comprises a catheter body which comprises a front section catheter and a rear section catheter. The head of the front section catheter is provided with a drainage hole, the tail of the rear section catheter is provided with a spiral evacuating catheter, a group of arched ribs are arranged between the front section catheter and the rear section catheter, the ribs are distributed at intervals in the circumferential direction of the catheter body, and the ribs jointly form an olive shape. A guide wire penetrates the catheter body through an evacuating catheter opening, after the catheter body completely sleeves the guide wire, the ribs are straightened, and thus the catheter can be smoothly inserted in a ureter from the fistulization oral; the guide wire is drawn out, the ribs recover to the arched state and accordingly the ribs are clamped in the ureter to achieve a catheter fixing effect, and urine enters the catheter body from the drainage hole and is finally discharged out the body from the evacuating catheter. The catheter does not need to be inserted in the kidney, postoperation problems such as calculus and infection are not caused, surgical operation is simple, and the cost is low. The evacuating catheter is spiral, and urine backflow can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ostomy urinary catheter. Background technique [0002] Cystostomy is a fistula in the suprapubic bladder due to urethral obstruction or cystectomy to drain urine out of the body. At present, double "J" tubes are generally used for indwelling. However, the insertion of double "J" tubes is a time-consuming and difficult link. Stones, causing blockage, can also lead to postoperative symptoms such as infection. Contents of the invention [0003] The object of the present invention is to provide a ostomy urinary catheter, which does not need to be inserted into the kidney, does not cause postoperative problems such as calculus and infection, and is simple in operation and low in cost. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] An ostomy catheter comprises a catheter body, the catheter body includes a fr...
