Abstract

According to one aspect of the present invention, a sensor for diagnosing a physiological or physical state includes a measurement system configured to determine clinical data for one or more parameters related to the physiological or physical state, a first memory configured to store the clinical data, a transmitter configured to transmit the clinical data according to a first communications protocol, a receiver configured to receive enhanced data according to a second communications protocol, and a second memory configured to store the enhanced data. The enhanced data is based on the clinical data.

Claims

1. A sensor for diagnosing a physiological or physical state, comprising:

a measurement system configured to determine clinical data for one or more parameters related to the physiological or physical state;

a first memory configured to store the clinical data;

a transmitter configured to transmit the clinical data according to a first communications protocol;

a receiver configured to receive enhanced data according to a second communications protocol, the enhanced data being based on the clinical data; and

a second memory configured to store the enhanced data.

2. The sensor of claim 1, wherein the clinical data is stored in the first memory and transmitted by the transmitter in an unencrypted state.

3. The sensor of claim 2, wherein the enhanced data is in an encrypted state when received by the receiver and stored in the second memory.

4. The sensor of claim 3, wherein the enhanced data includes hashing.

5. The sensor of claim 1, further comprising a controller configured to operatively control the measurement system, the transmitter, and the receiver, the controller being further configured to delete the clinical data from the first memory in response to the receiver receiving the enhanced data based on the clinical data.

6. The sensor of claim 1, wherein the clinical data includes a first set of one or more data fields and the enhanced data includes the first set of one or more data fields and one or more additional data fields.

7. The sensor of claim 6, wherein the one or more additional data fields includes data relating to at least one of a statistical analysis, a predictive trend, or a recommended medication dosage based on the clinical data.

8. The sensor of claim 1, wherein the clinical data includes a measured blood glucose concentration.

9. A method of managing medical data, comprising:

determining, using a sensor, clinical data for the one or more parameters relating to a physiological state or a physical state of an individual;

storing the clinical data in a first memory of the sensor;

transmitting the clinical data from the sensor to a collector according to a first communications protocol;

receiving enhanced data from a collector according to a second communications protocol, the enhanced data being based on the clinical data; and

storing the enhanced data in a second memory of the sensor.

10. The method of claim 9, further comprising deleting the clinical data in the first memory after the enhanced data is received.

11. The method of claim 9, wherein the enhanced data is in an encrypted state when received by the sensor.

12. The method of claim 10, wherein the clinical data includes a first set of one or more data fields and the enhanced data includes the first set of one or more data fields and one or more additional data fields, the one or more additional data fields including data relating to at least one of a statistical analysis, a predictive trend, or a recommended medication dosage based on the clinical data.

13. The method of claim 9, wherein the first communications protocol is a publicly available industry standard communications protocol and the second communications protocol is a non-publicly available custom communications protocol.

14. The method of claim 9, further comprising:

receiving the clinical data at the collector according to the first communications protocol;

processing the clinical data, using the collector, to determine the enhanced data; and

transmitting the enhanced data from the collector to the sensor.

15. The method of claim 14, wherein the collector comprises a personal computer, a tablet computer, or a mobile phone.

16. The method of claim 15, wherein the sensor is a biosensor configured to determine a concentration of an analyte in a fluid sample.

17. The method of claim 9, further comprising transmitting the enhanced data from the sensor to the collector according to the second communications protocol.

18. A sensor for diagnosing a physiological or physical state, comprising:

a measurement system configured to conduct a diagnostic analysis;

a transmitter and a receiver configured to transmit and receive data, respectively, according to a plurality of different communications protocols; and

computer-logic circuitry, including one or more controllers and one or more memory devices, the one or more memory devices storing instructions that, when executed by the one or controllers, cause the computer-logic circuitry to;

determine clinical data for one or more parameters related to the physiological or physical state;

store the clinical data in a first memory area of the one or more memory devices;

transmit the clinical data to a collector according to a first one of the plurality of communications protocols;

receive enhanced data, based on the clinical data, from the collector according to a second one of the plurality of communications protocols; and

store the enhanced data in a second memory area of the one or more memory devices.

19. The sensor of claim 18, wherein the instructions further cause the computer-logic circuitry to delete the clinical data from the first memory area.

20. The sensor of claim 18, wherein the clinical data is unencrypted and the enhanced data is encrypted.
