Medical Uses of Urine Bag (Urinary Drainage Bag)

Urine bag (urinary drainage bag) is a medical-grade PVC bag attached to a urinary catheter used to collect and store urine temporarily after draining the urine through the catheter.

It is used to treat people with health challenges that affect the urine flow, such as urinary incontinence, urinary retention, surgery that requires the catheter.

In a urine bag, a connector secures it to the urinary catheter while the flexible, kink-resistant drainage tube ensures the urine bag is well placed. There are mounting slots that are strengthened to help secure the bag vertically.

Urine bags come in different drain valve models such as pull-push, cross valve and screw valve. This will ensure they can empty the urine bag in various situations. Another non-return valve ensures no backflow of urine or risk of any ascending infection.

They manufacture urinary drainage bags using transparent materials to help with observation and monitoring.

We have a pediatric urine bag that can collect urine from infants. This type of drainage bag has adhesive fixing ring made from foam-based material. The material provides secure positioning and prevents leakage.

The tube length of the drainage bag is 90 or 120 cm. It can also come in different volume ranging from 100ml, 200ml, 500ml, 750ml, 1000ml. 1500ml and 2000ml.

Urine bag can be sterile (ethylene oxide) or not sterile. The shelf-life is 5 years. A good urine bag should be latex-free, exhibit no irritation or infection.

There are different urinary drainage bags, such as

  • Hanging (large bag that can store large urine volume used for immobile bedridden patients, and also while sleeping)
  • Leg-Mounted (smaller bag that can keep small volume and allows day-to-day movement)
