Abstract

A method and system for both autonomous and manual control of an infusion pump for delivering medication to a patient is provided.

Claims

1. An infusion pump system, comprising an infusion pump body, a control system connected to a user interface, and an RFID reader external to the infusion pump body, wherein the RFID reader is in communication with the control system, wherein the RFID reader is configured to provide device-assisted data entry to enter a foodstuff identification directly received from an RFID source of a foodstuff to the control system of the infusion pump system, and wherein the control system prompts user input of an amount of said foodstuff in response to said RFID reader directly receiving said foodstuff identification from the RFID source of said foodstuff.

2. The system of claim 1, wherein the infusion pump system comprises:

a medicine reservoir insertable into an interior space of the infusion pump body through an opening in the infusion pump body;

a drive system positioned in the pump body; and

a user-accessible button positioned along the infusion pump body.

3. The system of claim 1, wherein the RFID reader is contained within the infusion pump body, or forms part of the infusion pump body.

4. The system of claim 1, wherein the control system is configured to use the entered foodstuff identification to retrieve foodstuff composition information.

5. The system of claim 4, wherein said foodstuff composition information is retrieved from an onboard data repository of said infusion pump system, and wherein the foodstuff composition information retrieved by the infusion pump system includes at least one of carbohydrate, fat, and protein composition information of a foodstuff.

6. An infusion pump system, comprising an infusion pump body, a control system connected to a user interface, and an RFID reader, wherein the RFID reader is in communication with the control system, wherein the RFID reader is configured to provide device-assisted data entry to enter a foodstuff identification directly received from an RFID source of a foodstuff to the control system of the infusion pump system, wherein the control system prompts user input of an amount of said foodstuff in response to said RFID reader directly receiving said foodstuff identification from the RFID source of said foodstuff, wherein the control system is configured to use the entered foodstuff identification to retrieve foodstuff composition information, and wherein the control system is configured to determine a recommended bolus amount based at least partially on the foodstuff composition information.

7. The system of claim 6, wherein the control system is configured to determine said recommended bolus amount based at least partially on user metabolism information, and wherein the control system is configured to determine said recommended bolus amount based at least partially on a user'"'"'s food on board and insulin on board information.

8. The system of claim 7, wherein the control system is configured to determine said recommended bolus amount based the following equation:

Recommended bolus amount=Food Now*Carb Ratio+(BG−

BGtarget)*insulin sensitivity−

IOB+FOB,

where;

IOB=f(t)*bolus;

FOB=f(t)*grams Carb Ratio+f(t)*grams Protein Ratio+f(t)*grams Fat ratio; and

Food Now=the amount and type of foodstuffs ingested expressed in terms of grams, carbohydrates, proteins or fat.
