Closed-loop glucose control startup
First Claim
1. An apparatus comprising:
- a controller to receive one or more signals based on glucose sensor measurements, said controller comprising one or more processors to;
detect a request for entry of an automatic mode of operation of a glucose monitoring and insulin delivery system for a patient; and
control said entry of said automatic mode of operation based, at least in part, on a detected rate of change of blood glucose concentration of the patient by delaying initiation of a continual phase of said automatic mode of operation at least until said detected rate of change of blood glucose concentration of the patient is less than a predetermined rate of blood glucose change.

Abstract
Disclosed are methods, systems, etc. for closed-loop glucose control startup. In certain example embodiments, a request for entry of an automatic mode of operation of a glucose monitoring and insulin delivery system for a patient may be detected. An entry of the automatic mode of operation may be controlled based, at least in part, on a detected rate of change of blood glucose concentration of the patient. In certain other example embodiments, initiation of a continual phase of an automatic mode of operation may be controlled based, at least in part, on a time since a most recent manual delivery of a bolus, on a detected rate of change of blood glucose concentration, on a targeted fixed set point, a combination thereof, and so forth.

10. An apparatus comprising:
a controller to receive one or more signals based on glucose sensor measurements, said controller comprising one or more processors to; detect a request for entry of an automatic mode of operation of a glucose monitoring and insulin delivery system for a patient; and control said entry of said automatic mode of operation by delaying initiation of a continual phase of said automatic mode of operation until at least a predetermined length of time has elapsed since a most-recent manual delivery of a bolus of insulin.

11. An apparatus comprising:
a controller to receive one or more signals based on glucose sensor measurements, said controller comprising one or more processors to; detect a request for entry of an automatic mode of operation of a glucose monitoring and insulin delivery system for a patient; and control said entry of said automatic mode of operation by initiating a continual phase of said automatic mode of operation if a measured blood glucose concentration of the patient does not exceed a target blood glucose concentration for the patient.

12. An apparatus comprising:
a controller to receive one or more signals based on glucose sensor measurements, said controller comprising one or more processors to; detect a request for entry of an automatic mode of operation of a glucose monitoring and insulin delivery system for a patient; and control said entry of said automatic mode of operation by; calculating a correction bolus of insulin based, at least in part, on an insulin-on-board value and a target blood glucose concentration for the patient; and delivering said correction bolus of insulin to the patient if an amount of said correction bolus of insulin exceeds a predetermined minimum bolus amount. - View Dependent Claims (13)

14. An apparatus comprising:
a controller to receive one or more signals based on glucose sensor measurements, said controller comprising one or more processors to; detect a request for entry of an automatic mode of operation of a glucose monitoring and insulin delivery system for a patient; and control said entry of said automatic mode of operation by initiating a continual phase of said automatic mode of operation if said detected rate of change of blood glucose concentration of the patient does not exceed a first predetermined rate of blood glucose change. - View Dependent Claims (15, 16)

17. An apparatus comprising:
a controller to receive one or more signals based on glucose sensor measurements, said controller comprising one or more processors to; detect a request for entry of an automatic mode of operation of a glucose monitoring and insulin delivery system for a patient; and control said entry of said automatic mode of operation by; delaying initiation of a continual phase of said automatic mode of operation until at least a predetermined length of time has elapsed since a most-recent manual delivery of a bolus of insulin; and after at least said predetermined length of time has elapsed, initiating said continual phase of said automatic mode of operation after a measured blood glucose concentration of the patient is less than a target blood glucose concentration for the patient. - View Dependent Claims (18, 19)
