OCCLUSION DETECTION
First Claim
Patent Images
1. A system for occlusion detection, comprising:
- a syringe pump for a syringe containing a medication, wherein the syringe includes a plunger and said syringe pump includes a plunger driver;
a bendable element integrally formed with said plunger driver; and
a force sensor integrally formed with said plunger driver, wherein upon occurrence of an occlusion, the plunger exerts a force backwardly against said bendable element, thereby deflecting said bendable element into contact with said force sensor to thereby generate a signal indicating the occurrence of the occlusion.

Abstract
A system for occlusion detection could include a syringe pump for a syringe containing a medication, wherein the syringe includes a plunger and the syringe pump includes a plunger driver. A bendable element could be integrally formed with the plunger driver, and a force sensor could also be integrally formed with the plunger driver. Upon occurrence of an occlusion, the plunger would exert a force backwardly against the bendable element, thereby deflecting the bendable element into contact with the force sensor to thereby generate a signal indicating the occurrence of the occlusion.
