INTEGRATED INSULIN DELIVERY SYSTEM WITH CONTINUOUS GLUCOSE SENSOR
First Claim
Patent Images
1. An integrated system for monitoring a glucose concentration in a host and for delivering insulin to the host, the system comprising:
- a continuous glucose sensor, wherein the continuous glucose sensor is configured to substantially continuously measure a glucose concentration in a host, and to provide sensor data associated with the glucose concentration of the host;
an electronics module comprising a bolus controller module configured to iteratively determine an insulin therapy instruction in response to an evaluation of a relationship of internally derived data and an engageable bolus constraint, wherein a relationship of internally derived data to the bolus constraint is evaluated in response to engagement of the bolus constraint, and wherein the bolus constraint comprises a maximum total insulin dose that can be delivered within a predefined time period in response to engagement of the bolus constraint; and
an insulin delivery device configured to deliver insulin to the host, wherein the insulin delivery device is at least one of physically connected to a receiver and/or operably connected to a receiver, and wherein the insulin delivery device is configured to receive the insulin therapy instruction from the controller module.

15. An method for monitoring a glucose concentration in a host and for delivering insulin to the host, the method comprising:
-
providing sensor data associated with the glucose concentration of the host; evaluating a relationship of internally derived data and an engageable bolus constraint; determining an insulin therapy instruction, using a bolus controller module of a processor, in response to the evaluation, wherein a relationship of internally derived data to the bolus constraint is evaluated in response to engagement of the bolus constraint, and wherein the bolus constraint comprises a maximum total insulin dose that can be delivered within a predefined time period in response to engagement of the bolus constraint; and delivering insulin to the host based on the insulin therapy instruction from the bolus controller module. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
