SYSTEM FOR MONITORING SAFETY IN MEDICATION DELIVERY FOR DIABETES MANAGEMENT
First Claim
1. An integrated diabetes management system, comprising:
- a glucose sensor configured to provide sensor glucose data representative of sensed glucose;
a delivery device configured to deliver medication in response to a delivery control signal;
a controller programmed to receive glucose data and to provide an output control signal as a function of the received glucose data; and
a safety layer programmed to receive at least one of the sensor glucose data and the output control signal, and to modify at least one of the sensor glucose data and the output control signal;
wherein the glucose data would be modified to become modified glucose data; and
wherein the output control signal would be modified to become a modified output control signal that would be provided as the delivery control signal.

Abstract
An integrated diabetes management (IDM) system includes a safety layer which, in one configuration has two components, one located between a glucose sensor and a controller and a second component located between a controller and a pump, to monitor various aspects of signals and modify those signals for compatibility and safety purposes. In one application, the safety layer receives output control signals from a controller and modifies those control signals as a function of an actual amount of insulin delivered to the user. The safety layer allows for an increased level of safety in the IDM system and permits development of separate hardware and software upgrades with the safety layer assuring that compatibility between components will continue.

16. A method of diabetes management, comprising:
-
sensing glucose and providing sensor glucose data representative of sensed glucose; delivering medication in response to a delivery control signal; receiving glucose data and providing an output control signal as a function of the received glucose data; monitoring the amount of medication delivered; and receiving at least one of the sensor glucose data and the output control signal, and modifying at least one of the sensor glucose data and the output control signal; wherein the glucose data would be modified to become modified glucose data; wherein the output control signal would be modified to become a modified output control signal; communicating the modified output control signal as the delivery control signal; and wherein modifying at least one of the glucose data and the output control signal includes modifying as a function of the monitored amount of medication delivered. - View Dependent Claims (17, 18, 19, 20)
