Abstract: A system for determining drug administration information may comprise an input device providing for user input of feed forward information having a first parameter component and a second parameter component, a data storage device and a processor. The data storage device may have stored therein a map correlating values of the first and second parameters to drug administration information. The processor may be responsive to user input of the feed forward information to determine corresponding drug administration information according to the map.

Abstract: A system providing for user intervention in a medical control arrangement may comprise a first user intervention mechanism responsive to user selection thereof to produce a first user intervention signal, a second user intervention mechanism responsive to user selection thereof to produce a second user intervention signal, and a processor executing a drug delivery algorithm forming part of the medical control arrangement. The processor may be responsive to the first user intervention signal to include an intervention therapy value in the execution of the drug delivery algorithm, and responsive to the second user intervention signal to exclude the intervention therapy value from the execution of the drug delivery algorithm. The medical control arrangement may be a diabetes control arrangement, the drug delivery algorithm may be an insulin delivery algorithm, and the intervention therapy value may be, for example, an intervention insulin quantity or an intervention carbohydrate quantity.
