System and method for mode switching
Systems and methods described provide dynamic and intelligent ways to change the required level of user interaction during use of a monitoring device. The systems and methods generally relate to real time switching between a first or initial mode of user interaction and a second or new mode of user interaction. In some cases, the switching will be automatic and transparent to the user, and in other cases user notification may occur. The mode switching generally affects the user's interaction with the device, and not just internal processing. The mode switching may relate to calibration modes, data transmission modes, control modes, or the like.
1 . A method of automatically changing modes in a diabetes management system, comprising:
operating a monitoring device in a therapeutic mode during which glucose of a user is monitored and the monitored glucose is used to base insulin dosing decisions for the user;
while operating the monitoring device in the therapeutic mode, operating the monitoring device in a first calibration mode;
performing a first transition to operate the monitoring device in a non-therapeutic mode during which glucose of the user is monitored and glucose information is provided to the user, but the monitored glucose is not used to base insulin dosing decisions for the user, wherein criteria for performing the first transition are at least partially based on a glucose range of a current glucose value of the user and a time-of-day; and
responsive to the first transition, performing a second transition to operate the monitoring device in a second calibration mode, wherein the first calibration mode comprises one of a user-dependent calibration mode or a factory calibration mode and wherein the second calibration mode comprises a different one of the user-dependent calibration mode or the factory calibration mode.
2 . The method of claim 1 , wherein the first calibration mode is the user-dependent calibration mode, and wherein the second calibration mode is the factory calibration mode.
3 . The method of claim 1 , wherein the first calibration mode is the factory calibration mode, and wherein the second calibration mode is the user-dependent calibration mode, and wherein second criteria for performing the second transition include a number of blood glucose measurements entered into the monitoring device as calibration values exceeding a predetermined threshold over a predetermined period of time.
4 . The method of claim 1 , wherein the first transition is further based on a level of data usability passing a threshold.
5 . The method of claim 1 , wherein the therapeutic mode is a first phase of an artificial pancreas system, and wherein the non-therapeutic mode is a second phase of the artificial pancreas system.
6 . The method of claim 1 , further comprising displaying an indication of the therapeutic mode or the non-therapeutic mode on a user interface, and wherein providing the glucose information to the user comprises causing display of the glucose information on the user interface.
7 . The method of claim 1 , wherein the first transition is caused by data received from sensor electronics, data from diagnostic routines, or signal quality data.
8 . A method of automatically changing modes in a diabetes management system, comprising:
operating a monitoring device in a non-therapeutic mode during which glucose of a user is monitored and glucose information is provided to the user, but the monitored glucose is not used to base insulin dosing decisions for the user;
while operating the monitoring device in the non-therapeutic mode, operating the monitoring device in a first calibration mode;
performing a first transition to operate the monitoring device in a therapeutic mode during which glucose of the user is monitored and the monitored glucose is used to base insulin dosing decisions for the user, wherein criteria for performing the first transition are at least partially based on a glucose range of a current glucose value of the user and a time-of-day; and
responsive to the first transition, performing a second transition to operate the monitoring device in a second calibration mode, wherein the first calibration mode comprises one of a user-dependent calibration mode or a factory calibration mode and wherein the second calibration mode comprises a different one of the user-dependent calibration mode or the factory calibration mode.
9 . The method of claim 8 , wherein the first transition is further based on a level of data usability passing a threshold.
10 . The method of claim 8 , further comprising displaying at least one of an indication of the non-therapeutic mode or the therapeutic mode on a user interface.
11 . The method of claim 1 , wherein the first calibration mode is the user-dependent calibration mode, and wherein the second calibration mode is the factory calibration mode.
12 . The method of claim 1 , wherein, during the therapeutic mode, insulin is delivered to the user, and wherein, during the non-therapeutic mode, insulin is not delivered to the user.
13 . The method of claim 1 , wherein, during the therapeutic mode, recommendations are provided to the user, and wherein, during the non-therapeutic mode, the recommendations are not provided to the user.
14 . The method of claim 1 , wherein the glucose range of the current glucose value of the user is hyperglycemia, and the time-of-day is daytime.
15 . The method of claim 1 , wherein second criteria for performing the second transition are based on a patient specific glucose profile or a level of confidence in a sensor of the monitoring device reaching a predetermined threshold.
16 . The method of claim 1 , wherein the user-dependent calibration mode comprises a calibration routine that uses blood glucose concentration values from an external meter, and the factory calibration mode comprises a different calibration routine performed by the monitoring device without the blood glucose concentration values from the external meter.
17 . The method of claim 8 , wherein the glucose range of the current glucose value of the user is hypoglycemia, and the time-of-day is nighttime.
