Model-based infusion site monitor
First Claim
1. A medication delivery monitoring device comprising:
- a user interface configured to receive input information, wherein the input information includes patient information;
a vascular access device (VAD) configured to deliver a medication to an infusion site region of a patient;
a sensor that measures a plurality of fluid state parameters of a fluid delivery channel through which the medication is delivered by the VAD to the infusion site region of a patient;
a processor that creates a model of a state of the infusion site region based on the plurality of measured fluid state parameters and the input information, wherein the state of the infusion site region comprises a fluid volume and protein mass for (i) plasma within a blood vessel at the infusion site region, (ii) tissue at the infusion site region, and (iii) tissue surrounding the infusion site region; and
an output device that provides a communication, based on the model, regarding the state of the infusion site region.

Abstract
A medication delivery monitoring device is disclosed. The device includes a user interface configured to receive input information, and a sensor configured to measure a plurality of fluid state parameters of a fluid delivery channel through which the medication is delivered by a vascular access device (VAD) to an infusion site region of the patient. The device also includes a processor configured to determine a state of the infusion site region based on the plurality of measured fluid state parameters and the input information, and an output device configured to provide a communication regarding the state of the infusion site region. Methods and computer-readable mediums for monitoring medication delivery are also disclosed.

17. A method for monitoring medication delivery comprising:
-
receiving input information, wherein the input information includes patient information; infusing, using a vascular access device (VAD), a medication to an infusion site region of a patient; measuring a plurality of fluid state parameters of a fluid delivery channel through which the medication is delivered by the VAD to an infusion site region of a patient; modeling, with a processor, a state of the infusion site region based on the plurality of measured fluid state parameters and the input information, wherein the state of the infusion site region comprises a fluid volume and protein mass for (i) plasma within a blood vessel at the infusion site region, (ii) tissue at the infusion site region, and (iii) tissue surrounding the infusion site region; and providing a communication, based on the model, regarding the state of the infusion site region. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A medication delivery monitoring device comprising:
-
a user interface configured to receive input information; a vascular access device (VAD) configured to deliver a medication to an infusion site region of a patient; a sensor that measures a plurality of fluid state parameters of a fluid delivery channel through which the medication is delivered by the VAD to the infusion site region of a patient; a processor that creates a model of a state of the infusion site region based on the plurality of measured fluid state parameters and one or more of a weight of the patient, a height of the patient, a body surface area of the patient, an age of the patient, and a gender of the patient, wherein the state of the infusion site region comprises a fluid volume and protein mass for (i) plasma within a blood vessel at the infusion site region, (ii) tissue at the infusion site region, and (iii) tissue surrounding the infusion site region; and an output device that provides a communication, based on the model, regarding the state of the infusion site region.
