Male External Catheter is a non-invasive medical device for male urinary management, usually made of soft and elastic materials (such as silicone, latex, etc.) and structured like a sleeve. It is mainly suitable for male patients who cannot control urination independently due to urinary incontinence, postoperative recovery period, mobility impairment, etc. By being slipped over the penis, it drains urine into a urine collection bag to achieve the collection and management of urine. This product does not need to be inserted into the urethra, which can reduce damage and irritation to the urethra, lower the risk of infection, and provide patients with a more comfortable way of urinary management.
