Techniques for managing fluid delivery device operating mode transitions

Abstract

Techniques disclosed herein relate to managing transitions into fluid delivery device operating modes. In some embodiments, the techniques involve obtaining status information pertaining to operation of a fluid delivery device, the status information including fluid delivery data, exiting a closed-loop operating mode of the fluid delivery device based on the status information, and, after exiting the closed-loop operating mode, causing generation of a user notification recommending a remedial action to improve viability of a subsequent instance of the closed-loop operating mode. The closed-loop operating mode is an operating mode in which dosage commands are automatically generated based on sensor measurement data.

         2 . The processor-implemented method of  claim 1 , wherein the remedial action improves the viability of the subsequent instance of the closed-loop operating mode by reducing a likelihood that the subsequent instance of the closed-loop operating mode will automatically exit after reentry. 
     
     
         3 . The processor-implemented method of  claim 1 , wherein the user notification recommending the remedial action includes one or more user notifications to manipulate a blood glucose meter to obtain one or more blood glucose measurement values. 
     
     
         4 . The processor-implemented method of  claim 1 , wherein the remedial action includes calibrating, replacing, or recharging a sensor arrangement. 
     
     
         5 . The processor-implemented method of  claim 1 , further comprising determining the viability of the subsequent instance of the closed-loop operating mode based on determining whether a control parameter of the closed-loop operating mode can be calculated based on the sensor measurement data. 
     
     
         6 . The processor-implemented method of  claim 1 , further comprising determining the viability of the subsequent instance of the closed-loop operating mode based on determining at least one of viability, reliability, or accuracy of the sensor measurement data. 
     
     
         7 . The processor-implemented method of  claim 1 , wherein the status information indicates that one or more parameters of the closed-loop operating mode are invalid or unreliable.
