Abstract

A system for at least partial closed-loop control of a medical condition is disclosed. 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

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.

2. The method of claim 1 further comprising wherein shutting down the system comprising alerting the user of the shutdown through a series of alarms.

3. 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.

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.

5. The method of claim 4 further comprising wherein shutting down the system comprising alerting the user of the shutdown through a series of alarms.

6. 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.

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.

8. 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.

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.

10. 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.
