摘要： A closed loop control system for a medical drug delivery device logs historical data such as drug delivered and corresponding physiological parameters such as blood glucose level. On the basis of the logged historical data, the system calculates an estimated event forecast on which basis the system further calculates the necessary, prudent future drug delivery profile in order to counter delay in the closed loop. The estimated event forecast is presented to the user, the user is thereby given the possibility to accept, reject or adjust the event forecast and the corresponding drug delivery profile. Dynamic and adaptive safety limits to the drug delivery and the physiological parameter can be set by the user and will dynamically follow the drug delivery profile and the event forecast and will further optimize based on the learned behavioural pattern of the user. The user can set the safety level as a percentage of deviation to the drug delivery profile.
