What types of drainage bags are there

Classification by Clinical Specialty and Purpose (Most Commonly Used Classification)
Urological Drainage Bags

Standard Urine Bag: The most basic type, used for urine collection after short-term indwelling catheterization.

Anti-reflux Urine Bag: The core upgraded function. It has a built-in one-way valve or a special design to prevent urine/bacteria from flowing back into the bladder, greatly reducing the risk of urinary tract infections. It has become the mainstream clinical practice.

Precision Urine Bag (with graduations): The bag has precise graduations (usually accurate to milliliters), used for critically ill patients, patients undergoing surgery, or patients requiring strict monitoring of urine output.

Leg Bag/Daytime Urine Bag: Small and flat, it can be strapped to the leg for convenient daily activities and good concealment.

Urine Collection Bag: Larger capacity (usually 2 liters or more), used for long-term drainage while bedridden at night, reducing the frequency of changes.

Surgical/Wound Drainage Bags

Abdominal Drainage Bag: Used to collect exudate, blood, digestive fluids, etc., after abdominal surgery or in cases of abdominal infection. Typically needs to be connected to an abdominal drainage tube (such as a T-tube or silicone tube).

Bile drainage bag: Specifically used after T-tube drainage to collect bile and observe its color, characteristics, and volume.

Chest drainage bag: Used after pneumothorax or pleural effusion drainage, after removal of the closed chest drainage bottle, to connect a thinner drainage tube for continuous or intermittent drainage.

Wound drainage bag/high-volume drainage bag: Used for wounds with large exudates, such as after incision and drainage of large-area burns or soft tissue infections. Large capacity, and the opening design facilitates connection to various wound drainage tubes.

Other specialized drainage bags

External ventricular drainage bag: Used for ventricular drainage in neurosurgery. It requires extremely high sterility and precise calibration, and is usually used with a manometry tube; it is a precision management device.

Orthopedic negative pressure drainage bag: It can be connected to wound negative pressure drainage dressing to collect postoperative wound bleeding. It usually has a certain negative pressure or is connected to a central negative pressure.
