What It Is
Greystone Medical Urinary Drainage Bag is a sterile, 600ml closed-system leg bag designed for discreet daytime urine collection for patients using indwelling urinary catheters. Its compact profile makes it well-suited for wearing on the thigh or lower leg during normal daily activities, offering a more discreet alternative to larger bedside bags. Each bag comes individually packaged in an easy peel-open sterile pouch and is single-use only.
Integrated Anti-Reflux Device
Like its larger counterpart, the 600ml bag features a built-in anti-reflux valve that prevents collected urine from flowing back up the drainage tube toward the catheter and bladder. This helps reduce the risk of contamination and urinary tract infection associated with backflow, making it a safer choice for patients who are mobile throughout the day.
Compact Design for Active Use
The 600ml capacity is specifically suited for daytime wear, when patients are upright and moving. Because gravity naturally supports drainage in an upright position, smaller leg bags are practical for active users who prefer a lower-profile option that fits discreetly under clothing. The bag should be positioned below the level of the bladder at all times to ensure proper drainage.
Easy Drainage and Monitoring
The single-hand clicker-style drain clamp allows for quick and controlled emptying without assistance, which is especially important for patients managing their catheter independently. Due to its smaller capacity compared to a bedside bag, more frequent emptying is expected — particularly during periods of high fluid intake. The measurement scale printed on the bag makes it easy to track output at a glance.
Needleless Sampling Port
The integrated needleless sampling port allows healthcare providers to collect urine samples for testing without disconnecting the closed system, reducing the risk of contamination and simplifying routine sample collection.
Safety and Construction
The bag is sterile, latex-free, and designed as a closed system to minimize infection risk during use. It includes a built-in air escape valve and is manufactured for single use only — it must not be resterilized or reused. The transparent bag material allows for easy visual monitoring of urine color and clarity throughout the day.
