Now you can follow up to five people simultaneously. Right on your phone, The CareLink™ Connect app provides an easy way to view the sensor glucose levels of a person with diabetes using some Medtronic devices. When a family member or a friend has diabetes, you want to be supportive and stay close. You might want to know if their glucose levels go too high or too low, be able to quickly and easily access their insulin pump or Continuous Glucose Monitoring (CGM) system information. To remotely access sensor glucose levels or pump system information, care partners need to install the CareLink™ Connect app on their smartphone. Additionally, the person with diabetes must have a compatible MiniMed™ insulin pump or CGM connected to the CareLink™ software through the corresponding patient mobile app. For more information about the CareLink™ Connect app, please visit medtronicdiabetes.com or contact a Medtronic representative. IMPORTANT NOTE: For real-time updates, the app must consistently receive data from the CareLink™ server, while the insulin pump or CGM system must continually upload data to the CareLink™ server. The CareLink™ Connect app exclusively supports the MiniMed ™ 700-series insulin pump and selected CGM systems. It does not support all other CGM systems, MiniMed™, or Paradigm™ insulin pumps. To find a list of compatible smartphones, please visit medtronicdiabetes.com/app-check. The CareLink™ Connect app is intended to provide a secondary display of insulin pump and CGM (Continuous Glucose Monitor) data on a supported mobile device. CareLink™ Connect app is not intended to replace the real-time display of insulin pump or CGM data on the primary display device. All therapy decisions should be based on the primary display device. CareLink™ Connect app is not intended to analyze or modify the insulin pump and CGM data that it receives. Nor is it intended to control any function of the insulin pump or CGM system to which it is connected. CareLink™ Connect app is not intended to receive information directly from the insulin pump or CGM system. This app is not intended to be a substitute for professional medical advice, diagnosis, or treatment.
