Monitor for blocked condition in tube for fluid infusion pump
First Claim
1. A monitor for a blocked condition in a tube for a fluid infusion pump having a fluid container connected to said tube and head means for operating on said tube to cause a fluid transportation through said tube, said monitor comprisingdetector means for detecting selectively at times separated by a constant interval or at times separated by uniformly increasing intervals a condition of said tube between said fluid container and said head means, andcontrol means for monitoring for a blocked condition in said tube by comparing a most recently outputted value from said detector means selectively with a predetermined constant value or an earlier outputted value from said detector means.

Abstract
A monitor monitors for a blocked condition in a tube for a fluid infusion pump by detecting a condition of the tube by a sensor at predetermined time intervals and identifying a blocked condition in this tube by analyzing the detected values according to a specified criterion.

10. A monitor for a blocked condition in a tube for a fluid infusion pump having a fluid container connected to said tube and head means for operating on said tube to cause a fluid transportation through said tube, said monitor comprising
detector means for detecting a condition of said tube between said fluid container and said head means, sampling means for sampling values detected by said detector means at times with increasing intervals therebetween, memory means for storing values sampled by said sampling means, and judging means for comparing said sampled values and identifying as blocked condition in said tube according to a specified criterion, whereby said monitor monitors for a blocked condition in said tube.
