The system includes at least one medical fluid pump. The medical fluid pump including a sensor for determining the volume of fluid pumped by the pump. Also, at least one continuous analyte monitor, and a controller. The controller is in communication with the medical fluid pump and the at least one continuous analyte monitor. The controller includes a processor. The processor includes instructions for delivery of medical fluid based at least on data received from the at least one continuous analyte monitor. ## Claims ### Claim 1 A method for at least partial closed-loop control of a medical condition, the method comprising: receiving glucose data during a time frame or an event; comparing the glucose data to a previous and similar time frame or event; determining an unexpected result during the time frame or the event; sending an alert signal to indicate an unexpected result comprising alerting a user of the unexpected result; prompting the user to enter information regarding the unexpected result; and wherein if the system does not receive information regarding the unexpected result from the user, shutting down the system. ### Claim 2 (depends on 1) The method of claim 1 further comprising wherein shutting down the system comprising alerting the user of the shutdown through a series of alarms. ### Claim 3 (depends on 2) The method of claim 2 further comprising wherein alerting the user of the shutdown through a series of alarms comprising alerting the user of the shutdown through a series of increasing alarms. ### Claim 4 A method for at least partial closed-loop control of a medical condition, the method comprising: receiving medical fluid delivery data during a time frame or an event; comparing the medical fluid delivery data to a previous and similar time frame or event; determining an unexpected result during the time frame or the event; sending an alert signal to indicate an unexpected result comprising alerting a user of the unexpected result; prompting the user to enter information regarding the unexpected result; wherein if the system does not receive information regarding the unexpected result from the user, shutting down the system. ### Claim 5 (depends on 4) The method of claim 4 further comprising wherein shutting down the system comprising alerting the user of the shutdown through a series of alarms. ### Claim 6 (depends on 5) The method of claim 5 further comprising wherein alerting the user of the shutdown through a series of alarms comprising alerting the user of the shutdown through a series of increasing alarms. ### Claim 7 A method for at least partial closed-loop control of a medical condition, the method comprising: receiving glucose data during a time frame or an event; comparing the glucose data to a previous and similar time frame or event; determining an unexpected result during the time frame or the event; sending an alert signal to indicate an unexpected result comprising alerting a user of the unexpected result; prompting the user to enter information regarding the unexpected result; wherein if the system does not receive information regarding the unexpected result from the user, shutting down the system; and wherein shutting down the system comprising alerting the user of the shutdown through a series of alarms. ### Claim 8 (depends on 7) The method of claim 7 further comprising wherein alerting the user of the shutdown through a series of alarms comprising alerting the user of the shutdown through a series of increasing alarms. ### Claim 9 A method for at least partial closed-loop control of a medical condition, the method comprising: receiving medical fluid delivery data during a time frame or an event; comparing the medical fluid delivery data to a previous and similar time frame or event; determining an unexpected result during the time frame or the event; sending an alert signal to indicate an unexpected result comprising alerting a user of the unexpected result; prompting the user to enter information regarding the unexpected result; wherein if the system does not receive information regarding the unexpected result from the user, shutting down the system; and wherein shutting down the system comprising alerting the user of the shutdown through a series of alarms. ### Claim 10 (depends on 9) The method of claim 9 further comprising wherein alerting the user of the shutdown through a series of alarms comprising alerting the user of the shutdown through a series of increasing alarms.
