Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a urinary catheter with built-in bioelectric stimulation. Background Art

[0002] The bladder is an important organ in the human urinary system. The main function of the bladder is to temporarily store urine and complete urination. Urination is completed under a series of complex neuromuscular coordination.

[0003] When the urine in the bladder accumulates and the urethral pressure continues to increase, it will induce the urination reflex of the bladder. The nerve impulse is transmitted to the urination center. The urination center can send the impulse to the cerebral cortex. After receiving the impulse, the cerebral cortex issues a command and induces the urination reflex, which will relax the urethral sphincter and contract the bladder detrusor. Through the coordination of the muscles, the urine in the bladder is discharged from the body, completing the urination reflex of the human body.

[0004] If the patient has an indwelling catheter, the urination process lacks the participation of the urination center, and the urine is directly discharged from the body through the catheter. For patients with long-term indwelling catheterization, the urethral sphincter is not used for a long time, and the muscle will relax and atrophy. Therefore, it is easy to leak urine around the catheter and the urine cannot be discharged autonomously after the catheter is removed, resulting in various adverse consequences such as incontinence dermatitis, urinary retention, urinary tract infection, and re-indwelling catheter. It causes great pain to patients in clinical practice and increases the economic burden of patients.

[0005] To address this clinical problem, catheter clamping training is performed before removing the catheter, but the effect is less than ideal; when urine leakage occurs around the catheter, it is often necessary to replace the catheter with a larger diameter, but this problem cannot be completely solved.

[0006] Therefore, the present invention proposes a urinary catheter with built-in bioelectric stimulation to solve the above problems. Summary of the invention
