Gesture-based control of diabetes therapy

Abstract

Techniques disclosed herein relate to gesture-based control of diabetes therapy. In some embodiments, the techniques may involve identifying at least one gesture indicative of utilization of an injection device for preparation of an insulin injection based on user activity data obtained from a wearable device disposed on an arm of a user. The techniques may further involve based on the at least one identified gesture, determining whether the insulin injection meets criteria of a proper insulin injection. The techniques may further involve outputting information indicative of whether the criteria is satisfied based on the determination.

         7 . The system of  claim 1 , further comprising a patient device, wherein the patient device includes the one or more processors. 
     
     
         8 . The system of  claim 1 , wherein the instructions further cause performance of:
 determining a time for a subsequent injection of insulin;   determining whether the user is attempting to use the injection device to inject insulin based on movement detected by the wearable device prior to the time for the subsequent injection of insulin; and   outputting data presenting an alert to the user that the user had already injected insulin based on the determination that the user is attempting to use the injection device to inject insulin prior to the time for the subsequent injection of insulin.   
     
     
         9 . The system of  claim 1 , wherein the instructions further cause performance of:
 outputting data indicative of a modification to correct an impropriety associated with the insulin injection or increase an efficacy of the insulin injection based on the determination indicating that the criteria is not satisfied.   
     
     
         10 . The system of  claim 1 , wherein the instructions further cause performance of:
 outputting data directing the injection device to automatically modify the insulin injection or prevent the insulin injection based on the determination indicating that the criteria is not satisfied.   
     
     
         11 . The system of  claim 1 , wherein the instructions further cause performance of:
 generating data presenting a set of instructions for properly administering the therapy to a patient, the set of instructions indicating a correct insulin type, an appropriate dose of the correct insulin type, a safe injection area to receive the appropriate dose of the correct insulin type, a recommended trajectory when motioning the injection device to inject the appropriate dose of the correct insulin type, an orientation or a position to hold the injection device before following the recommended trajectory to the safe injection area, or a time interval between insulin injections.   
     
     
         12 . The system of  claim 11 , wherein the instructions further cause performance of:
