System and method for detecting occlusion using flow sensor output |
摘要 |
A method of detecting an occlusion for an infusion therapy in one embodiment includes: monitoring an output signal from a flowrate sensor for a pulsatile fluid flow having a frequency range, the pulsatile flow being through a fluid pathway to a patient; acquiring a data set that includes the output signal as a function of time; filtering the data set with a noise rejection filter to produce a filtered data set; performing spectra analysis on the filtered data set to determine a strength of the output signal in a frequency domain; calculating a signal strength for the frequency range using the strength of the output signal in the frequency domain; and comparing the signal strength of the range to at least one threshold level to determine if an occlusion is present during the infusion therapy. |
