Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a power-assisted male intermittent urinary catheterization auxiliary device. Background Art

[0002] Neurogenic bladder (NGB) is one of the problems facing urology today. NGB is a dynamic process. Some patients may have lower urinary tract dysfunction for life, which requires continuous treatment and management. Intermittent catheterization is the gold standard for the treatment of neurogenic lower urinary tract dysfunction (NLUTD) with bladder emptying dysfunction. For patients with spinal cord injury (SCI), epidemiological surveys have found that the most common injury segment is the cervical cord, up to 31.5% to 55%. High SCI patients have difficulty performing self-cleaning intermittent catheterization (CIC) due to their hand dysfunction, and the current clinical treatment is suprapubic cystostomy (SPT). 40% to 50% of patients who use ostomy tubes for a long time will experience blockage, causing urine leakage and urine retention, which causes great trouble to patients and their families. It may also cause complications such as urinary tract infection, stoma tube obstruction, secondary knots, stoma leakage, stoma granulation edema, stoma tube dislocation, bladder irritation, stoma infection, and difficulty in tube removal.

[0003] In summary, for patients with high SCI (C5 and above), due to combined hand dysfunction, patients are unable to perform self-cleaning intermittent catheterization, and patients experience anxiety and depression, fear of socializing, and decreased quality of life. Summary of the invention
