LOW COST DISPOSABLE INFUSION PUMP
First Claim
1. An infusion pump configured to pump fluid through a flexible tubing, wherein the tubing has an upstream end and a downstream end, comprising:
- an armature configured to compress the tubing when in a first position and uncompress the tubing when in a second position; and
an occlusion detector configured to detect the position of the armature and identify upstream or downstream occlusions in the flexible tubing.

Abstract
Disclosed is a low cost, disposable, infusion pump. The infusion pump can include an integrated occlusion detector that detects both upstream and downstream occlusions in an infusion tube. In addition, the infusion pump can easily monitor flow rates through the infusion tube, and be quickly set to infuse at a pre-determined rate. An armature within the infusion pump works in concert with a pair of tubing pinchers to precisely control the movement of fluid within the tubing. Sensors mounted within the device detect the position of the armature and can determine if an occlusion has occurred in the tubing.

12. A method of detecting an occlusion in an infusion tube, comprising:
-
providing an infusion pump comprising an armature configured to compress the infusion tube when in a first position and uncompress the infusion tube when in a second position; instructing the armature to compress and uncompress the infusion tube to move fluid through the infusion tube; and sensing an error when the armature does not move as instructed, wherein the error indicates an occlusion in the infusion tube. - View Dependent Claims (13, 14, 15, 16, 17, 18)
