Methods and Systems For Detecting an Occlusion
First Claim
Patent Images
1. A method for detecting an occlusion, the method comprising:
- receiving a signal corresponding to a first force needed to deliver a first material;
indicating that an occlusion exists if the first force is greater than a baseline value plus a delta value;
setting, if the first force is less than or equal to the baseline value plus the delta value, and if a turbulence factor is less than a threshold value, the baseline value equal to a second force;
receiving a signal corresponding to a third force needed to deliver a second material; and
indicating that an occlusion exists if the third force is greater than the baseline value plus the delta value.

Abstract
Systems and methods for detecting an occlusion may include receiving a signal corresponding to a first force needed to deliver a first material through the tube. Furthermore, the systems and methods may include indicating that an occlusion exists if the first force is greater than a baseline value plus a delta value, the baseline value being assigned a value equal to the force necessary to deliver the first material through the tube in an un-occluded state and the delta value being assigned a value configured to create a desired level of sensitivity.
