The urine leg bag is a medical device designed to collect urine from patients who are unable to void urine naturally or require continuous urinary drainage. The device is attached to the patient's leg using straps or adhesive, allowing for hands-free mobility.

Urine leg bags are typically made of durable and flexible materials such as PVC or polyethylene, which can withstand movement and pressure without leaking or tearing. The bag usually has a graduated scale to accurately measure urine output, and an anti-reflux valve to prevent urine backflow and reduce the risk of contamination.

The urine leg bag features a comfortable and discreet design, allowing patients to wear the device under their clothing without discomfort or embarrassment. The bag is typically equipped with a drainage valve or port, making it easy to empty and clean when needed.
