Description

Urinary catheter with plastic stent and sterilizing device for the stent

technical field

The utility model relates to the field of medical instruments, in particular to a urinary catheter with a plastic stent and a sterilizing device for the stent.

Background technique

Urinary catheterization is one of the most common clinical treatment methods. It refers to inserting a catheter into the bladder through the urethra to draw out the urine in the bladder. Most of the catheters commonly used in clinical practice are made of rubber or silicone. .

With the aging of the society, the population of elderly men is increasing. Prostatic hyperplasia is a common disease of elderly men. Prostatic hyperplasia will lead to bladder neck elevation, posterior urethra stenosis, and urethra lengthening, narrowing and bending. , The clinical manifestations are difficulty urinating spontaneously, and even acute urinary retention occurs, that is, a large amount of urine accumulated in the bladder cannot be excluded. Acute urinary retention can cause severe discomfort and upper urinary tract dysfunction in patients.

Clinically, an indwelling catheter is usually used to drain the urine in the patient's bladder to treat acute urinary retention, but because the patient's urethra becomes longer, narrower and bends, the catheter itself is flexible, and it is a flexible catheter when inserted. It is difficult to enter the bladder through the deformed urethra, and the friction of the catheter against the deformed urethra during insertion increases the risk of urethral mucosal injury.

Aiming at the problem that the catheter is difficult to insert, at present, a hard metal stent is mainly placed in the catheter to increase the hardness of the catheter, thereby facilitating the insertion of the catheter. However, in clinical practice, a hard metal stent is used. The shape of the catheter is fixed and cannot be bent according to the shape of the urethra. When the catheter is placed, it is easy to cause symptoms of urethral mucosal damage, formation of false urethra, and even prostate damage and bleeding. Urine drainage can only be performed on patients with suprapubic cystostomy for urine drainage, which increases the pain and economic burden of patients, and prolongs the hospital stay. At the same time, urethral mucosal damage and the formation of false urethral tract will significantly increase the incidence of long-term urethral stricture in patients, and further treatment is required.
