Built-in hidden urinary catheter for male

Abstract

The invention discloses a built-in hidden urinary catheter for the male. The urinary catheter comprises a head part, a tube part and a mechanical control valve located in the tube; the head part is fixed in the urinary bladder cavity, and the head part is provided with a urine inlet; the tube part is arranged in the male urethra, and the tail end of the tube part is provided with a urine outlet; the mechanical control valve is opened under the function of external force, and urine enters the urinary catheter through the urine inlet and flows out of the urine outlet and is discharged out of thebody through the external urethral orifice. The urinary catheter has the advantages that the urinary catheter is slightly shorter than the male urethra and does not stay out of the body, the risk ofbacterial infection is reduced, and the situation is prevented that the urinary catheter is dragged out due to misoperation of a patient and the urethra is damaged; moreover, the inconvenience of carrying a urine bag by the patient suffering from urinary incontinence for a long time is overcome, the damage of carrying the urine bag for a long time to the urinary bladder muscles is reduced, the patient can live normally accordingly, the appearance of the urinary catheter is the same as that of a normal person, the life quality of the patient is improved to a certain degree, and the psychological stress of the patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a male built-in concealed urinary catheter. Background technique [0002] The treatment of neurogenic bladder is a hitherto unsolved medical problem. Urinary catheterization is currently a routine method for the treatment of neurogenic bladder. But this treatment can not make people finish normal urination, can only carry urethral urine bag for a long time, brings great inconvenience to the life of patient itself. There are also some new urinary catheter technologies coming out: [0003] The first idea is to use magnetic attraction to control the urinary catheter valve, and control the human body to urinate autonomously through abdominal pressure. Although it can solve the problem of continuous urination of the urinary catheter, the continuous compression of the bladder by the support member of the device is likely to cause ischemic injury; [0004] The second idea is...

Problems solved by technology

[0004] The second idea is to fix the urinary catheter by the bulge of the neck of the bladder and the apex of the male prostate, or replace the bulge with a balloon lumen. However, since the urinary catheter still needs to be exposed outside the body, the fixed part must have a certain degree of hardness. It can also cause excessive compression of the bladder neck
