Urethral catheter capable of preventing urine leakage

Abstract

The invention provides a urethral catheter capable of preventing urine leakage, and relates to the field of urethral catheters. The urethral catheter capable of preventing urine leakage comprises a urine pipeline, an inflation pipeline and a flushing pipeline, a first urine inlet is formed in one end of the urine pipeline, and a urine collecting opening is formed in the other end of the urine pipeline; an air bag is arranged outside the urine pipeline close to the urine inlet and is communicated with the inflation pipeline; the urine pipeline is positioned at the rear part of the air bag and is also provided with a second urine inlet, and a one-way valve is arranged in the urine pipeline; the urethral catheter further comprises a urethral sleeve which sleeves the urine pipeline, the front end of the urethral sleeve is provided with a pasting part used for being bonded with the penis or the vulva of the patient, the rear end of the urethral sleeve is in sealing connection with the rear portion of the second urine inlet, and a urine leakage collection space is formed between the urethral sleeve and the urine pipeline. The second urine inlet is used as an auxiliary opening, so that urine leaked into the urethral sleeve can return into the urine pipeline again, the problem of urine leakage caused by poor contact between the urine pipeline and the urethral orifice is solved, and the urine can be guided effectively.

Description

technical field [0001] The invention relates to the technical field of urinary catheters, in particular to a urinary catheter for preventing urine leakage. Background technique [0002] For patients with prostate and bladder diseases, during postoperative indwelling catheterization treatment, a catheter is used to insert the patient's urethral opening to drain the urine in the bladder into a urine storage bag. However, due to the looseness of the patient's urethral opening and the mismatch of the size of the catheter, the adhesion between the catheter and the urethral opening will not be strong, and then there will be leakage of urine, especially for patients who need bladder irrigation. The situation will be more serious. [0003] For example, the Chinese invention patent application with application publication number CN109498963A and application publication date of 2019.03.22 discloses a bladder irrigation catheter, and specifically discloses that the bladder irrigation ...
