The sterile bag with T-stop is indicated for urinary drainage and drainage of other body fluids in catheterized patients. It is used in hospitals, surgical wards, urology, intensive care, nursing homes, and home care settings, where precise urine output monitoring or temporary drainage is required. The device's sterility also makes it suitable for situations requiring high levels of hygiene and infection control. The anti-reflux valve and various tubing lengths ensure safe, comfortable use, and adaptability to the patient's clinical condition.
