Abstract

A variable data usage personal medical system including a self-care device attached to a patient, and operable to generate self-care device data and to transmit the self-care device data at a fixed interval; a cellular communication device operable to receive and store the transmitted self-care device data, to register a count at an interval counter for each of the fixed intervals in which the transmitted self-care device data is received, to generate a data cellular packet from overhead plus the stored self-care device data when the interval counter equals a fixed interval index, and to transmit the data packet; and a cloud infrastructure operably connected to the cellular communication device over a cellular network, and operable to receive, process, and store the transmitted data packet. The cloud infrastructure is operable to transmit a value for the fixed interval index to the cellular communication device for storage.

Claims

a self-care device attached to the patient, the self-care device being operable to generate self-care device data and to transmit the self-care device data at a fixed interval;

a cellular communication device operably connected to the self-care device, the cellular communication device being operable to receive and store the transmitted self-care device data, to store an interval counter and to increment the interval counter for each of the fixed intervals in which the transmitted self-care device data is received, and in response to determining that the interval counter equals a fixed interval index, to generate a data cellular packet from overhead plus the stored self-care device data and to transmit the data packet, wherein the fixed interval index controls how often data packets are transmitted from the cellular communication device; and

a cloud infrastructure operably connected to the cellular communication device over a cellular network, the cloud infrastructure being operable to receive, process, and store the transmitted data packet;

wherein the cellular communication device is operable to store the fixed interval index and the cloud infrastructure is operable to transmit a value for the fixed interval index to the cellular communication device for storage.

2. The system of claim 1 wherein the cloud infrastructure is further operable to generate and transmit display data from the transmitted data packet, and the system further comprises a display device operably connected to the cloud infrastructure, the display device being operable to present the transmitted display data.

3. The system of claim 2 wherein:

the display device is further operable to generate a first display device data request when the display device is enabled and transmit the first display device data request to the cloud infrastructure;

the cloud infrastructure is further operable to send a wake up message to the cellular communication device in response to the first display device data request;

the display device is further operable to generate repeated display device data requests and transmit the repeated device data requests to the cloud infrastructure;

the cloud infrastructure is further operable to send repeated cloud infrastructure data requests to the cellular communication device;

the cellular communication device is further operable to send data cellular packets to the cloud infrastructure in response to each of the repeated cloud infrastructure data requests, one of the data cellular packets being sent each time the self-care device sends self-care device data to the cellular communication device;

the cloud infrastructure is further operable to generate continuous display data from the data cellular packets and transmit the continuous display data to the display device; and

the display device is further operable to display the continuous display data.

4. The system of claim 2 wherein:

the display device is further operable to generate a first display device data request when the display device is enabled and transmit the first display device data request to the cloud infrastructure;

the cloud infrastructure is further operable to send a toggle command to the cellular communication device in response to the first display device data request to toggle a value of a continuous communication index of the cellular communication device;

the cellular communication device is further operable to change operating state in response to the value of the continuous communication index, the operating state being one of a continuous mode and a normal mode;

wherein, in the continuous mode, the cellular communication device sends the data cellular packet to the cloud infrastructure every time the cellular communication device receives self-care device data from the self-care device; and

in the normal mode, the fixed interval index governs how often the cellular communication device sends the data cellular packet to the cloud infrastructure.

5. The system of claim 2 wherein the value for the fixed interval index is a first value, the display device is further operable to generate a data interval increase request when the display device is enabled, the data center is further operable to send a wake up message and a second value for the fixed interval index to the cellular communication device in response to the data interval increase request, the first value being greater than the second value.

6. The system of claim 5 wherein the second value is 1, the cellular communication device being operable to transmit the data packet to the data center at each of the fixed intervals.
