NON-INVASIVE SYSTEM AND METHOD FOR A FLUID FLOW MONITORING SYSTEM

摘要

A non-invasive system and method is provided for a fluid delivery system of the type including a fluid delivery pump delivering fluid in pulses through a fluid delivery tube. The non-invasive monitoring system and method includes a sensor which is brought into engagement with an outer surface of the fluid delivery tube. The sensor is adapted for being calibrated at an initial temperature and is responsive to the fluid when passing through the fluid delivery tube. In particular, the present system and method is adapted to monitor the sensor and receives datacorresponding to the changes in the initial temperature of the sensor as influenced by the temperature of the fluid when passing through the fluid delivery tube. The non-invasive monitoring system and method is further adapted to process the datafrom the sensor indicative of both the initial and changed temperatures for determining the status of the fluid in the fluid delivery tube. A display can also be provided for notifying the user of the device of the status of the fluid in the fluid delivery tube.
