Abstract
The present invention provides an accurate method and apparatus for sensing and monitoring any buildup in the downline tubing pressure in a fluid infusion system. The initial fluid pressure as indicated by the tubing location is sensed after a delay period and is utilized as a base pressure if it is within allowable limits. The infusion tubing location or pressure is then monitored and compared with the base location or pressure. The system will alarm if a preset differential location or pressure change is exceeded.
