Insulin pump having missed meal bolus alarm

Abstract

A pump for delivering insulin to a user. The pump comprises a pump mechanism and a meal-bolus program module. The meal-bolus program module is programmed to control the pump mechanism to deliver a meal bolus. An alarm program module is in data communication with the alarm, the timer, and the meal-bolus program module. The alarm module is programmed to generate an alarm signal when the meal-bolus program module does not control the pump mechanism to deliver a meal bolus within a predetermined period of time.

1 . A method of operating an insulin pump, the method comprising: 
 entering into the pump an interval; and    generating an alarm signal if a predetermined event is not delivered during the interval.    
   
   
       2 . The method of  claim 1  wherein entering into the pump a predetermined interval of time includes entering into the pump an end time for the interval.  
   
   
       3 . The method of  claim 2  wherein entering into the pump a predetermined interval of time further includes entering into the pump a start time for the interval.  
   
   
       4 . The method of  claim 1  wherein generating an alarm signal if a predetermined event is not delivered during the interval includes generating an alarm signal if a meal bolus is not delivered during the interval.  
   
   
       5 . A method of operating an insulin pump, the insulin pump configured to selectively deliver a meal bolus, the method comprising: 
 entering a time into the pump; and    generating an alarm signal if a meal bolus is not delivered before the time lapses.    
   
   
       6 . The method of  claim 5  wherein entering a time into the pump includes defining an interval.  
   
   
       7 . The method of  claim 6  wherein defining an interval includes entering an end time for the interval.  
   
   
       8 . The method of  claim 7  wherein defining an interval further includes entering a start time for the interval.  
   
   
       9 . The method of  claim 8  wherein generating an alarm signal if a meal bolus is not delivered before the time lapses includes generating an alarm signal if a meal bolus is not delivered between the start time and the end time.  
   
   
       10 . The method of  claim 6  wherein generating an alarm signal if a meal bolus is not delivered before the time lapses includes generating an alarm signal if a meal bolus is not delivered during the interval.
