1. An apparatus for reviewing medicament delivery commands for a system providing closed loop therapy to a patient with an ambulatory infusion pump, comprising:
- a memory adapted to store at least one acceptable operation parameter for closed loop delivery of medicament with an ambulatory infusion pump;
a processor communicatively coupled with the memory, the processor configured to;
communicate with a device that calculates at least one medicament delivery parameter for delivery of medicament to a patient in a closed loop system based at least in part on data relating to glucose levels of the patient;
review one or more medicament delivery parameters calculated for delivery of medicament in the closed loop system;
determine whether it is permissible for the ambulatory infusion pump to deliver the medicament according to the one or more medicament delivery parameters based on the at least one acceptable operation parameter for closed loop delivery of medicament with the ambulatory infusion pump stored in the memory; and
enable the ambulatory infusion pump to deliver the medicament according to the one or more medicament delivery parameters if it is determined that it is permissible for the ambulatory infusion pump to deliver the medicament according to the one or more medicament delivery parameters.

11. A system for providing closed loop therapy to a patient with an ambulatory infusion pump, comprising:
-
an ambulatory infusion pump; a device configured to receive data relating to glucose levels of the patient and calculate at least one medicament delivery parameter for delivery of medicament to the patient based on the data relating to glucose levels; and a safety processor configured to communicate with the device to receive and review one or more medicament delivery parameters calculated by the device, determine whether it is permissible for the ambulatory infusion pump to deliver the medicament according to the one or more medicament delivery parameters based on at least one acceptable operation parameter for closed loop delivery of medicament with the ambulatory infusion pump, and enable the ambulatory infusion pump to deliver the medicament according to the one or more medicament delivery parameters if it is determined that it is permissible for the ambulatory infusion pump to deliver the medicament according to the one or more medicament delivery parameters. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
