Publication number: 20220181015Abstract: A system for monitoring a patient includes a memory and processing circuitry coupled to the memory. The processing circuitry is configured to determine a glucose level of the patient and determine a first graphical representation of the glucose level for display on a patient device based on the glucose level of the patient. The processing circuitry is further configured to determine a second graphical representation of the glucose level for display on a wearable device based on a target range of glucose levels. The second graphical representation is different from the first graphical representation. The processing circuitry is further configured to output an instruction to cause the wearable device to display the second graphical representation.Type: ApplicationFiled: December 7, 2021Publication date: June 9, 2022Inventors: Natassia Mattoon, David Legray, Joseph P. Williams, Yuxiang Zhong

Publication number: 20220105269Abstract: In general, techniques are described for automated projection mode for switching glucose levels. A device for assisting in therapy delivery comprising a memory and a processor configured to perform the techniques. The memory may store first projected levels of glucose in a patient over a first time frame. The processor may determine an occurrence of a projection event that alters how projected levels of glucose are to be output, and automatically determine, based on the projection event, a second time frame that differs from the first time frame, The processor may also obtain a current glucose level of the patient, obtain, based on the current glucose level, second projected levels of glucose in the patient over the second time frame, and output the second projected levels of glucose for the second time frame.Type: ApplicationFiled: September 22, 2021Publication date: April 7, 2022Inventors: Yuxiang Zhong, Pratik J. Agrawal, Chantal M. McMahon, Dae Kang, David Legray, Nicole T. Robinson, Natassia Mattoon, Michael A. Hill

Publication number: 20220104761Abstract: In general, techniques are described for automatic disablement of alerts for diabetic conditions. A device including a memory and a processor may be configured to perform the techniques. The memory may store alert data. The processor may obtain projected levels of glucose in a patient over a time frame, and determine whether the projected levels of glucose leave a prescribed range. The processor may generate, when the projected levels of glucose in the patient leave the prescribed range during the time frame and based on the alert data, a graphical alert indicating that the projected levels of glucose will leave the prescribed range. The processor may further determine that a maintenance event alters the projected levels of glucose, and disable, without user input and based on the determination that the maintenance event alters the projected levels of glucose, the graphical alert for a temporary period of time.Type: ApplicationFiled: September 22, 2021Publication date: April 7, 2022Inventors: Yuxiang Zhong, Pratik J.
