Abstract

Methods for setting a basal rate profile for an insulin pump, wherein the basal rate profile defines a basal rate delivery for a selected time interval and has a pre-defined number of profile segments each of which define the basal rate delivery for a subset of the selected time interval, include providing a curve representing the basal rate as a continuous function of time as an input for an input unit and generating the basal rate profile from the curve by a calculation unit by assigning curve values at selected time instances to the pre-defined number of profile segments.

Claims

1. An apparatus that sets a basal rate profile, wherein the basal rate profile defines the basal rate delivery for a selected time interval and has a pre-defined number of profile segments each of which define the basal rate delivery for a subset of the selected time interval, the apparatus comprising:

a touch screen;

an input unit configured to receive input of a curve representing a basal rate as a continuous function of time by a movement of an object across a display area of the touch screen and by a scanning of a pre-drawn curve, wherein a selection can be made between the drawn or scanned curve; and

a calculation unit that is configured to generate the basal rate profile from the selected curve by an assignment of curve values at selected time instances to the pre-defined number of profile segments.

2. The apparatus of claim 1 further comprising a filter unit configured to smooth the selected curve.

3. The apparatus of claim 1 wherein the display area is configured to display an exemplary curve and a curve of past blood glucose values of a user, and to depict deviations of the blood glucose values from the exemplary curve.

4. The apparatus of claim 1 further comprising a scroll button of a computer to scroll the basal rate profile with respect to a time axis.

5. The apparatus of claim 1 further comprising an implantable insulin pump.

6. The apparatus of claim 1 wherein the basal rate profile defines the basal rate delivery for a 24 hour day as the selected time interval and the subset of the selected time interval for each profile segment comprises 1 hour such that it results in 24 hour profile segments.

7. The apparatus of claim 1 wherein the basal rate profile defines the basal rate delivery for a 24 hour day as a selected time interval and the subset of the selected time interval for each profile segment comprises 2 hours such that it results in 12 hour profile segments.

8. The apparatus of claim 1 wherein the basal rate profile defines the basal rate delivery for a 24 hour day as a selected time interval and the subset of the selected time interval for each profile segment comprises 30 minutes such that it results in 48 hour profile segments.

9. The apparatus of claim 1 further comprising the touch screen comprising a personal digital assistant (PDA) or personal computer (PC) that is connected to and separate from an insulin pump.

10. The apparatus of claim 1 wherein the input unit and the calculation are integrated into a personal digital assistant (PDA).

11. The apparatus of claim 1 further comprising an insulin pump, wherein the input unit and the calculation unit are separate devices that are each separate from the insulin pump.

12. The apparatus of claim 1 further comprising an insulin pump configured to perform basal delivery in a pulsed way.

13. The apparatus of claim 1 wherein the object is a stylus.

14. The apparatus of claim 1 wherein the touch screen is configured such that removal of the object from the display area determines the end of the curve.

15. An apparatus that sets a basal rate profile, wherein the basal rate profile defines the basal rate delivery a the selected time interval and has a pre-defined number of profile segments each of which define the basal rate delivery for a subset of the selected time interval, the apparatus comprising:

a personal digital assistant (PDA) comprising;

a touch screen;

an input unit configured to receive input of a curve representing a basal rate as a continuous function of time by a movement of an object across a display area of the touch screen and by a scanning of a pre-drawn curve, wherein a selection can be made between the drawn or scanned curve; and

a calculation unit that is configured to generate the basal rate profile from the selected curve by an assignment of curve values at selected time instances to the pre-defined number of profile segments;

wherein the display area is configured to display an exemplary curve and a curve of past blood glucose values of a patient, and to depict deviations of the blood glucose values from the exemplary curve.

16. The apparatus of claim 15 further comprising an insulin pump, wherein the basal rate profile is generated for the insulin pump that is configured for pulsed delivery, and the insulin pump is separate from the PDA.

17. The apparatus of claim 16 wherein the insulin pump is implantable.

18. The apparatus of claim 17 further comprising the calculation unit comprising a filter unit for smoothing the curve.

19. A method for setting a basal rate profile, wherein the basal rate profile defines the basal rate delivery for a selected time interval and has a pre-defined number of profile segments each of which define the basal rate delivery for the subset of the selected time interval, comprising:

providing an apparatus comprising;

a touch screen;

an input unit configured to receive input of a curve representing a basal rate as a continuous function of time by a movement of an object across a display area of the touch screen and by a scanning of a pre-drawn curve, wherein a selection can be made between the drawn or scanned curve; and

a calculation unit that is configured to generate the basal rate profile from the selected curve by an assignment of curve values at selected time instances to the pre-defined number of profile segments;

selecting between the drawn or scanned curve;

receiving, via the input unit, the input of the curve; and

generating, via the calculation unit, the basal rate profile from the curve by assigning the curve values at the selected time instances to the pre-defined number of the profile segments.

20. The method of claim 19 further comprising depicting, on the touch screen display area, an exemplary curve and a curve of past blood glucose values of a user, and depicting deviations of the curve of past blood glucose values from the exemplary curve.
