    A mechanical failure in continuous ambulatory peritoneal dialysis (CAPD) systems can lead to infection. A simple lock-ring device prevents disconnection of the catheter and titanium connector, reducing peritonitis risk.

    Area of Science:

    • Nephrology
    • Medical Device Engineering
    • Infectious Disease Prevention

    Background:

    • Continuous ambulatory peritoneal dialysis (CAPD) is a vital renal replacement therapy.
    • Standard CAPD systems face mechanical vulnerabilities, particularly at the catheter-connector interface.
    • Catheter disconnection poses a significant risk for bacterial contamination and peritonitis.

    Purpose of the Study:

    • To identify the cause of recurrent mechanical failures in a specific CAPD system.
    • To develop and evaluate a simple device to enhance the security of the catheter-titanium connector junction.
    • To mitigate the risk of bacterial entry and subsequent CAPD-associated peritonitis.

    Main Methods:

    • Analysis of a standard CAPD infusion/drainage system experiencing recurrent mechanical failure.

  • Development of a novel
  • Testing the efficacy of the lock-ring device in securing the silastic catheter and titanium connector junction.

    • Main Results:

    • The junction between the silastic catheter and titanium connector was identified as a point of mechanical failure.
    • This failure led to disconnection and increased risk of bacterial contamination.
    • The lock-ring device successfully created a secure joint at the catheter-titanium connector junction.

    Conclusions:

    • Recurrent mechanical failure at the CAPD catheter-titanium connector junction is a critical issue.
    • The developed lock-ring device provides a simple yet effective solution to secure the junction.
    • Implementing this device can significantly reduce the risk of peritonitis in CAPD patients.
