Glossary Entry: Closed System Catheter


Definition: A closed system catheter is a type of urinary catheter that is designed to minimize the risk of infection during catheterization. It consists of a pre-lubricated catheter with a collection bag attached, creating a closed circuit for urine drainage.

Detailed Description

Types and Variations

Variations: Closed system catheters may come in different lengths and diameters to accommodate varying patient needs. Some variations also include additional features such as insertion aids or hydrophilic coatings.


Common Uses: Closed system catheters are commonly used in clinical settings, especially for patients at risk of urinary tract infections or in need of long-term catheterization. They are also used for intermittent catheterization.

Insertion and Placement

Procedure: To use a closed system catheter, the healthcare provider or patient carefully follows the manufacturer’s instructions for insertion and placement. The insertion technique may involve the use of a sterile technique and the Seldinger technique for atraumatic insertion.

Clinical Considerations

Potential Complications

Risks: Potential complications of using a closed system catheter include urinary tract infections, urethral trauma, and bladder spasms. Proper technique and catheter care are important for minimizing these risks.

Care and Maintenance

Maintenance Requirements: It is important to maintain sterility during catheterization and to follow proper cleaning and storage procedures for the catheter and collection bag to prevent infection and ensure device integrity.

Additional Information

Related Devices

Associated Terms: Accessories such as sterile gloves, lubricant, and disinfectant wipes may be used in conjunction with closed system catheters.

Innovations and Advancements

Recent Developments: Recent advancements in closed system catheters include the incorporation of antimicrobial materials and improved drainage and collection systems.

Regulatory and Safety Notes

Regulations: Closed system catheters are regulated medical devices that must meet specific standards for safety and effectiveness set by regulatory agencies. Healthcare providers should follow guidelines for proper use and disposal of these devices.
