Fluid Dispensing Device with a Flow Detector
First Claim
1. A portable therapeutic fluid delivery device for delivering a therapeutic fluid into a body of a patient, the fluid delivery device comprising:
- a first part comprising,a driving mechanism,a flow detector comprising at least one heating element and at least two temperature sensors, anda processor;
a second part comprising,a reservoir,an exit port, anda delivery tube communicating between the reservoir and the exit port;
wherein the first part and the second part are designed such that upon pairing of the first part with the second part, the at least one heating element and the at least two temperature sensors touch the delivery tube, and wherein the processor, upon activation of the at least one heating element, detects a flow condition of the therapeutic fluid inside the delivery tube based on a signal provided by the at least two temperature sensors.

Abstract
A portable therapeutic fluid delivery device with a flow detector comprising a heating element and two temperature sensors is presented. Upon activation of the heating element, a flow condition of the fluid inside the delivery tube is determined based on a signal provided by the temperature sensors. A temperature gradient within the therapeutic fluid is detected. The determined flow condition can be one of: air bubbles within the delivery tube, occlusion within the delivery tube, or leakage within the delivery tube. The device can have two parts, for example, a reusable part and a disposable part. Upon pairing of these parts, the heating element and the temperature sensors touch the delivery tube.
