Abstract
Embodiments described herein include a medical monitoring system with a cloud communication interface in which individual components of the medical monitoring system, including medical sensors and data receiving devices are configured to communicate with remote cloud servers of the medical monitoring system using cellular networks. The remote cloud servers process medical data reported by the medical sensors and deliver data to the data receiving devices. The components of the medical monitoring system are low-cost and durable. The sensors are considered disposable after the expiration of their active use lifetime. The data receiving device can be manufactured using low-cost durable components to be protected against loss caused by accidental damage, destruction, or misplacement. Embodiments described herein further provide for authentication and for secure communication among the components of the medical monitoring system.
Core Innovation
The disclosed invention is a medical monitoring system that includes a medical sensor configured for contact with fluid under a skin of a patient and a medical data server configured to authenticate the medical sensor for use by an application executing on a first external device associated with a first user. The medical sensor includes a housing having storage memory and a cellular radio module, and the glucose sensor generates medical data indicative of levels of glucose in the fluid of the patient. The medical sensor provides the medical data to the medical data server by communicatively coupling via one or more cellular networks using the cellular radio module, and the medical data server subsequently provides the medical data to the first external device after authentication.
The invention further addresses temporary loss of communication between the medical sensor and the medical data server by determining that the medical sensor is temporarily unable to communicate with the medical data server via the one or more cellular networks. The medical sensor stores the medical data in the storage memory, and when the medical sensor is able to communicate again, the medical sensor provides the medical data stored in the storage memory to the medical data server by provision of a most recent recorded level of glucose to the medical data server before provision of other medical data stored in the storage memory.
In the system, server-side processing extends beyond authentication and data relaying. The medical data server associates received medical data with a patient identifier for the patient, generates a patient notification by processing sensor medical data, and sends the notification to the first external device over one or more cellular networks. The system also supports processing based on a determined location associated with the medical sensor using cellular networks and the cellular radio module, and forwarding processed medical data to another data server on behalf of the patient.
Claims Coverage
The independent claim explicitly defines one core medical monitoring system architecture and behavior. Its main inventive features cover sensor-to-cloud authenticated data transmission over cellular networks and on-sensor buffering with most recent recorded level retransmission ordering after temporary communication failure.
Authenticated glucose sensor communication via medical data server
A medical monitoring system comprising a medical data server configured to authenticate a medical sensor for use by an application executing on a first external device associated with a first user, where the medical sensor comprises a housing with storage memory and a glucose sensor configured for contact with fluid under a skin of a patient, and a cellular radio module; the medical sensor generates medical data indicative of levels of glucose and provides the medical data to the medical data server via one or more cellular networks using the cellular radio module, and provides the medical data to the first external device subsequent to medical data server authentication.
Cellular communication failure buffering with most recent-first retransmission
The medical sensor determines that the medical sensor is temporarily unable to communicate with the medical data server via the one or more cellular networks, stores the medical data in the storage memory, and subsequent to determination that the medical sensor is able to communicate with the medical data server again, provides the medical data stored in the storage memory to the medical data server by provision of a most recent recorded level of glucose before provision of other medical data stored in the storage memory.
Across the independent claim’s core architecture, the system integrates authenticated sensor use, cellular network data transport, and sensor-side storage to ensure that after a temporary connectivity failure, the most recent recorded glucose level is provided first when communication resumes.
Stated Advantages
Enables continued medical data handling during temporary communication failure by storing medical data and providing a most recent recorded glucose level first upon reconnection.
Supports delivery of glucose medical data to a first external device only after medical data server authentication of the medical sensor for use by an application on the first external device.
Allows server-side association of received medical data with patient identifier for the patient and generation of a patient notification sent to the first external device.
Enables location-based processing of medical data based on a location associated with the medical sensor determined using cellular networks.
Documented Applications
Medical monitoring using a glucose sensor in contact with fluid under a skin of a patient, with medical data transmission to a remote medical data server and delivery of medical data and/or patient notifications to an external device.
Server-based patient notifications derived from processing sensor medical data and sent to a first external device over one or more cellular networks.
Location-based processing of medical data associated with a medical sensor determined using cellular networks and a cellular radio module.
