Abstract

A diabetes management system having a reliable data management scheme is disclosed. The system comprises a plurality of devices, each device performing a different function relating to treatment of diabetes. Each device has a device identifier and each device generates data records relating to the function of the device. Each device includes a metadata generator configured to generate a metadata tag for a data record generated by the device. A metadata tag includes the device identifier of the corresponding device, a record identifier, and a source identifier indicating whether the record was originated by a human or the device. The system further includes a diabetes management device in communication with the plurality of devices and configured to manage records received from the plurality of devices. When a first device of the plurality of devices generates a new record to be communicated to the diabetes management device, the metadata generator of the first device generates a new unique record identifier and a new metadata tag based on the new unique record identifier and the device identifier of the first device, and the first device propagates the new record and the new metadata tag to the second device.

Claims

1. A diabetes management system having a reliable data management scheme, the system comprising:

a plurality of devices, each device performing a different function relating to treatment of diabetes of a patient and having a device identifier that identifies a type of the device, wherein each device generates data records relating to the function of the device, and each device includes a metadata generator configured to generate a metadata tag for a data record generated by the device, wherein the metadata tag includes the device identifier of the corresponding device, a record identifier, and a source identifier indicating whether the record was originated by a human or the corresponding device;

a diabetes management device in electronic communication with the plurality of devices, wherein the diabetes management device is configured to manage records received from the plurality of devices;

wherein when a first device of the plurality of devices generates a new record to be communicated to the diabetes management device, the metadata generator of the first device generates a new unique record identifier and a new metadata tag based on the new unique record identifier and the device identifier of the first device, and the first device propagates the new record and the new metadata tag to the second device.

2. The system of claim 1 wherein when the diabetes management device communicates the record being communicated to a second device of the plurality of devices, such that the metadata tag generated by the first device is propagated with the record from the diabetes management device to the third device.

3. The system of claim 1 wherein the diabetes management device includes a data management module that manages the data records received from the plurality of devices according to a set of predetermined rules.

4. The system of claim 3 wherein the set of predetermined rules include a rule which provides priority to data records having a source identifiers indicating that the data records were machine generated over data records having a source identifiers indicating that the data records were human generated.

5. The system of claim 1 further comprising a continuous blood glucose monitor having a corresponding device identifier that generates continuous blood glucose data records and transmits the continuous blood glucose data records to the diabetes management device, wherein the diabetes management device includes a proxy metadata generator that generates a metadata tag on behalf of the continuous blood glucose monitor, wherein the metadata tag includes the device identifier corresponding to the continuous blood glucose meter.

6. The system of claim 1 wherein the first device is one of an insulin pump, and a general purpose computer executing diabetes management software.

7. The system of claim 1 wherein the diabetes management device has a blood glucose monitor housed therein, wherein the blood glucose monitor generates blood glucose records and the diabetes management device includes a metadata generator that generates metadata tags for the blood glucose records, wherein the device identifier of the metadata tags for the blood glucose records is a device identifier of the diabetes management device.

8. The system of claim 1 wherein a particular metadata tag includes a checksum value that is determined using a predetermined function that uses contents of a particular data record at a time of creation as input, wherein validity of the particular data record can be verified by calculating a checksum check value using the predetermined function and the contents of the particular data record.

9. The system of claim 1 wherein the metadata tags generated by the metadata generator of each device include a time stamp.

10. A diabetes management system having a reliable data management scheme, the system comprising:

a first device performing a first function relating to treatment of diabetes and a first device type identifier associated thereto;

a diabetes management device in communication with the first device;

wherein the first device has associated therewith;

a) a record generation module that generates a record relating to the first function or relating to operating conditions of the first device;

b) a metadata generator that generates a new metadata tag for tagging the record, wherein the new metadata tag includes the first device type identifier, a record identifier that is a unique value associated with the first record, and a source identifier indicating whether the record was originated by a human or the first device;

c) a communication interface that allows the first device to communicate with a communication interface of the diabetes management device, wherein when the first device is to transmit the record to the diabetes management device, the first metadata generator generates the new metadata tag and the communication module transmits the record and the new metadata tag to the diabetes management device; and

wherein the new metadata tag is associated with the record for the duration of the record.

11. The diabetes management system of claim 10 wherein the first device is one of an insulin pump and a PC executing diabetes management software.

12. The diabetes management system of claim 10 further comprising a continuous blood glucose monitor having a corresponding device identifier that generates continuous blood glucose data records and transmits the continuous blood glucose data records to the diabetes management device, wherein the diabetes management device includes a proxy metadata generator that generates a metadata tag on behalf of the continuous blood glucose monitor, wherein the metadata tag includes the device identifier corresponding to the continuous blood glucose meter.

13. The system of claim 10 wherein the diabetes management device includes a data management module that manages the data records received from the plurality of devices according to a set of predetermined rules.

14. The system of claim 13 wherein the set of predetermined rules include a rule which provides priority to data records having a source identifiers indicating that the data records were machine generated over data records having a source identifiers indicating that the data records were human generated.

15. The system of claim 10 wherein the diabetes management device has a blood glucose monitor housed therein, wherein the blood glucose monitor generates blood glucose records and the diabetes management device includes a metadata generator that generates metadata tags for the blood glucose records, wherein the device identifier of the metadata tags for the blood glucose records is a device identifier of the diabetes management device.

16. The system of claim 10 wherein a particular metadata tag includes a checksum value that is determined using a predetermined function that uses contents of a particular data record at a time of creation as input, wherein validity of the particular data record can be verified by calculating a checksum check value using the predetermined function and the contents of the particular data record.

17. The system of claim 10 wherein the metadata tags generated by the metadata generator of each device include a time stamp.
