Leak protection enuresis auxiliary catheterization device

Technical Field

The utility model relates to the technical field of catheters, in particular to an auxiliary urethral catheterization device for preventing urinary leakage and enuresis.

Background

With the advent of an aging society, the incidence of urination disorders such as dysuria, frequent urination, and urinary incontinence has increased. Dysuria can not only make patients lose normal living ability and deprive people of dignity, but also reduce the consciousness of autonomous activities and seriously affect the life quality of the old patients. The most commonly used methods in the management of urinary dysfunction are catheterization and indwelling catheterization.

Catheterization is the medical science, inserts the catheter to the bladder through the urethra, and the drainage goes out urine. Is often applied to patients with urinary retention or difficult urination after operation in clinic. The prior common catheters for clinical use comprise a single-cavity catheter, a double-cavity catheter and a three-cavity catheter. The preparation materials mainly comprise polyvinyl chloride, dry rubber (crude rubber), silicon rubber and natural latex. Although the clinical application of the existing catheters is mature, some obvious problems can be caused due to structural defects. Such as: (1) during the catheterization indwelling period, partial patients have the phenomena of urine leakage and enuresis, and the urine overflows outwards along the outer surface of the catheterization tube. If the clothes are not changed frequently, the infection of the patient is easily caused; and brings great inconvenience to clinical care; (2) when clinical and scientific research needs to accurately measure urine, certain errors can be caused by urine leakage and enuresis. Then, the structure of the catheter is modified and innovated to solve the above problems, and the public reports are not found so far.
