Technical field

The present application relates to the technical field of medical devices, and more specifically, to an anti-clogging urinary catheter.

Background technique

Urinary drainage systems, such as urinary catheters, are known to be used in various hospital and medical settings to drain urine from the bladder. Urinary drainage systems provide a pathway for urine to flow from the patient's body into a urine container, such as a urine collection bag. This type of urine drainage system usually uses an indwelling urinary catheter connected to a urine container (such as a "leg bag"). Therefore, the system provides a flow path for urine from the patient's bladder to the urine container.

Typically, in-dwelling ("Foley") catheters are used routinely during many surgical procedures and are used by patients with urinary incontinence or persons with disabilities such as paraplegics or quadriplegics who may not be able to control urination. )use. Catheterization may be the only method of voiding management. The catheter is combined with a bag to collect urine, which can be emptied into the toilet.

For example, the distal end 112 of the catheter body 100 can be inserted into the user's bladder, so that the water bag 210 is placed in the bladder, and then the water filling valve 230 can be connected through a syringe, and water can be injected through the syringe through the water filling valve 230 and the water filling channel 220. The bladder 210 is injected with liquid, causing the bladder 210 to expand in the bladder to prevent the catheter from being withdrawn through the urethra, so that the distal end 112 of the catheter remains in the bladder, and the bladder 210 can also be formed at the bottom of the bladder Seal to stop urine leaking through the catheter. The water filling valve 230 can prevent the liquid in the water bag 210 from flowing toward the proximal end 111, prevent backflow, and keep the water bag 210 inflated.
