Drainage Bag is a sterile collection bag used in urinary catheter systems and wound drainage setups to collect and measure output from indwelling tubes and catheters. It features a calibrated collection chamber for volume monitoring and an anti-reflux valve to prevent backflow, which is critical for infection prevention in catheterized patients.

Drainage bags should be replaced on a regular schedule per clinical protocol and discarded after use. OxyCare supplies drainage bags and related urological and wound care supplies for home and hospice patients.
