Abstract

A multifunctional glucose monitoring system and method of measuring glucose level, determining insulin dosage, and indicating insulin dosage on a syringe is disclosed. The multifunctional glucose monitoring system includes standard functionality with respect to acquiring a blood glucose reading. However, in addition, the multifunctional glucose monitoring system includes a dosage algorithm for calculating an insulin dosage based on the blood glucose reading and any other useful parameters, and includes a built-in marking device for marking the calculated dosage level on the barrel of an insulin syringe that is installed in the body of the multifunctional glucose monitoring system. A method includes the steps of measuring the glucose level, determining an insulin dosage, and indicating the insulin dosage on a syringe.

Claims

1. A multifunction glucose meter, comprising:

a syringe port formed in a body of the multifunction glucose meter, wherein the syringe port is configured to accept a syringe;

a marking device, wherein the marking device is configured to place a mark on an exterior surface of a barrel of the syringe inserted into the syringe port;

a drive mechanism operatively connected to the marking device and configured to move the marking device along the length of the barrel of the syringe and into contact with the exterior surface of the barrel of the syringe inserted into the syringe port;

a test port;

transducer;

display and controller, wherein the test port is in operative communication with the transducer, and wherein the transducer and display are operatively connected to the controller;

a dosage algorithm that is interfaced with or integrated into the controller, wherein the dosage algorithm calculates an insulin dosage;

and wherein the controller linearly positions the marking device in accordance with the insulin dosage, and the marking device is positioned so as to place the marking device in contact with the exterior surface of the barrel of the syringe.

2. The meter of claim 1, wherein the dosage algorithm is implemented in at least on of software and hardware.

3. The meter of claim 1, wherein the mark is calibrated to indicate a particular dosage of insulin.

4. The meter of claim 3, wherein the calibration of the insulin dosage is based on a glucose reading performed by the glucose meter.

5. The meter of claim 4, wherein the mark on the barrel of the syringe indicates a point at which the barrel of the syringe is to be filled to provide the insulin dosage in accordance with the glucose reading from the glucose meter.

6. The meter of claim 1, further comprising a communication interface connected to the controller.

7. The meter of claim 1, further comprising at least one of a syringe sensor, ink level sensor, and marking strip level sensor.

8. The meter of claim 7, further comprising one or more indicators corresponding to the at least one of the syringe sensor, ink level sensor, and marking strip level sensor, wherein the one or more indicators are one of visual, audible, tactile, or combination thereof.

9. The meter of claim 1, wherein the marking device is disposed internally to the glucose meter and is proximate to the syringe port.

10. The meter of claim 9, wherein the syringe accepted into the syringe port is rotatable.

11. The meter of claim 10, further comprising a syringe drive mechanism proximate the syringe port and configured for rotating the syringe.

12. The meter of claim 1, wherein the marking device is rotatable about the exterior surface of the barrel of the syringe.

13. The meter of claim 1, where the marking device causes a mark on at least a portion of the barrel of the syringe.

14. The meter of claim 1, wherein the mark comprises an ink marking.

15. The meter of claim 14, wherein the ink marking comprises a high visibility/contrast color.

16. The meter of claim 1, wherein the mark comprises a strip adhered to the exterior surface of the barrel of the syringe.

17. The meter of claim 16, wherein the strip comprises a substantially transparent window formed therein.
