Closed System Urinary Catheters Patients

Closed System Catheters

Closed system catheters are one of the most preferred types of catheters among all wheelchair-ridden individuals, pediatric patients and several other types of patient groups. Unlike a straight catheter, a closed system offers better privacy and more convenience to the user.

Closed systems provide a secure and discreet catheterization process – whether one uses it in a restroom, a private room or even a vehicle. These catheters also offer an additional safety feature known as an Insertion Tip or an Introducer.

The tip of the introducer allows the pre-lubricated catheter to bypass some of the highest concentrations of bacteria (located within the urethra). This reduces the risk of infection significantly. Collection chambers, on the outside, allow users to measure outputs and monitor the level of hydration.

How it Works?

A closed system catheter comprises a rubber catheter which is inserted into the urinary bladder of a patient suffering from urinary incontinences. The catheter is then connected to a drainage bag through a tube. An inflated balloon retains the catheter within the bladder.

The drainage of urine in closed catheters depends on gravity. This means that the tubing and the drainage bag for collecting urine must be placed well below the bladder. For the best results and ease of use, it is recommended that the patient should:

  • Drink at least eight glasses of water daily, unless placed on fluid restrictions
  • Ensure that the catheter and tubes are placed in a good position
  • Allow the urine to flow freely into the drainage bag
  • Keep the area where the catheter enters the body clean and free from secretions


Placing a closed system catheter does not require special assistance and can easily be performed on a DIY basis. At the time of placement, ensure that there is sufficient slack in the tube, between the body and the thighs. This allows the patient to move his or her thighs easily without pulling apart the catheter.

The drainage bag can then be easily attached to the bed frame. It should never touch the floor and should always be kept well below the level of the patient’s bladder. Furthermore, the drainage bag needs to be emptied on an almost daily basis to prevent infection and reduce odors. 

Cleaning the Drainage Bag

Catheter care is an essential element of a closed system catheter. This ensures the system remains open and flowing, at all times. To empty the drainage bag and keep your catheter clean, simply follow these steps:

Carefully wash your hands and dry them thoroughly.

Assemble the following equipment:

  • A glass container or large plastic jar
  • A large sealable plastic storage bag
  • Alcohol wipes
  • Disposable gloves
  • Paper towels
  • Put on the disposable gloves
  • Place the container or jar under the drainage bag
  • Allow the urine to flow out of the bag into the container by releasing the clamp
  • Close the drain once the drainage bag is fully drained
  • Clean the end of the drain with an alcohol wipe
  • Discard the alcohol wipe into the plastic storage bag
  • Make sure that the catheter and tubes are placed correctly
