Time Sensitive Foley Catheter Alarm

Tech ID:

This device allows a caregiver to easily monitor the total time that a catheter has been in place via an integrated indicator. This indicator is activated at placement by means of a simple pull strip or other similar action and, once activated counts down to a preset expiration time.


The device was designed by a University of Texas Health Science Center at San Antonio surgeon/inventor intent on creating a unique Foley Catheter timer that would allow for an easy determination of dwell time.  A further feature of the device is a visual and/or aural indication then alerts the caregiver that the time has expired and the catheter should be changed, pulled, or other action taken in accordance with current SCIP guidelines.



In order to combat infection, the Center for Medicaid and Medicare is advocating guidelines for urinary catheter dwell time. The Center recommends that a catheter be changed within 48 hours of placement. Failure to do so must be documented by a caregiver along with a suitable explanation. As more hospitals are adopting these guidelines, the need for accurate monitoring of catheter placement times must be addressed. Current methods, such as noting times on charts, can be cumbersome and prone to inaccuracies or omissions. Having an integrated timing device as part of a catheter design allows a caregiver to quickly and accurately monitor placement times and also provides for protocol uniformity which may be readily adopted into hospital protocols.


Commercial Applications & Advantages:

This device is designed to be used by health care professionals who provide inpatient care and support services in a hospital or other clinical environment. Key market segments for the device include hospitals, medical clinics and nursing homes.


The integrated warning catheter provides a fast and convenient way to accurately monitor dwell times. While this catheter design is applicable to all patient care environments, it is especially useful in those clinics and hospitals that have adopted the Center for Medicaid and Medicare guidelines for combating urinary tract infections. This device overcomes the disadvantages of current manual methods of noting placement time which can be cumbersome and prone to mistake or omission.
