Continuous subcutaneous insulin infusion therapy
First Claim
1. A continuous subcutaneous insulin infusion therapy using a continuous subcutaneous insulin pump, which comprises:
- determining a circadian variation curve representing sympathetic nerve activity and a circadian variation curve representing parasympathetic nerve activity of a target patient;
acquiring inflection points of the circadian variation curve representing the sympathetic nerve activity and inflection points of the circadian variation curve representing the parasympathetic nerve activity;
detecting times which correspond to the inflection points; and
employing said times as points at which an insulin infusion rate of the continuous subcutaneous insulin infusion pump is changed.

Abstract
A mechanism for optimizing insulin infusion rate of a CSII pump for each patient. A continuous subcutaneous insulin infusion therapy uses a continuous subcutaneous insulin pump, which includes: determining a circadian variation curve representing sympathetic nerve activity and that represents parasympathetic nerve activity of a target patient; acquiring an inflection point of each of the circadian variation curves representing the two types of nerve activity; detecting a time that corresponds to the inflection point; and employing the time as a point at which the insulin infusion rate of the continuous subcutaneous insulin infusion pump is changed.

6. A method for operating a continuous subcutaneous insulin infusion pump, which comprises:
-
employing a circadian variation curve representing sympathetic nerve activity and a circadian variation curve representing parasympathetic nerve activity derived from a target patient for acquiring inflection points of the circadian variation curve representing the sympathetic nerve activity and inflection points of the circadian variation curve representing the parasympathetic nerve activity; detecting times which correspond to the inflection points; and employing said times as points at which an insulin infusion rate of the continuous subcutaneous insulin infusion pump is changed. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus for continuous subcutaneous insulin infusion therapy, which comprises:
-
a means for determining a circadian variation curve representing sympathetic nerve activity and a circadian variation curve representing parasympathetic nerve activity of a target patient using a probe attached to a target patient; an operational processing unit; and a continuous subcutaneous insulin infusion pump, wherein the operational processing unit has a means for detecting times which correspond to inflection points of the circadian variation curves representing the sympathetic nerve activity and inflection points of the circadian variation curve representing parasympathetic nerve activity to employ said times as points at which an insulin infusion rate of the continuous subcutaneous insulin infusion pump is changed. - View Dependent Claims (12, 13, 14, 15)
