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.

First claim

What is claimed is:

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 of a patient;
a first memory configured to store the clinical data, wherein the clinical data includes a first set of one or more data fields;
a transmitter configured to transmit the clinical data to a collector according to a first communications protocol, wherein the collector includes advanced processing functions to determine enhanced data based on processing the clinical data determined by the measurement system;
a receiver configured to receive the enhanced data according to a second communications protocol having a set of rules for data exchange that are not publicly available, the enhanced data including different information from the clinical data and wherein the enhanced data includes the first set of one or more data fields and one or more additional data fields, including a recommended medication dosage based on the clinical data, wherein the advanced processing functionality of the collector is omitted from the measurement system, and wherein the measurement system is not able to utilize the enhanced data; and
a second memory configured to store only 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 one or more additional data fields includes data relating to at least one of a statistical analysis or a predictive trend.

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

8. 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, wherein the clinical data includes a first set of one or more data fields;
transmitting the clinical data from the sensor to a collector according to a first communications protocol, wherein the collector includes advanced processing functions;
determining enhanced data based on the collector processing the clinical data determined by the measurement system;
receiving the enhanced data from the collector according to a second communications protocol having a set of rules for data exchange that are not publicly available, the enhanced data including different information from the clinical data and wherein the enhanced data includes the first set of one or more data fields and one or more additional data fields, including a recommended medication dosage based on the clinical data, wherein the advanced processing functionality of the collector is omitted from the measurement system, and wherein the measurement system is not able to utilize the enhanced data; and
storing only the enhanced data in a second memory of the sensor.

9. The method of claim 8 , further comprising deleting the clinical data in the first memory after the enhanced data is received.

10. The method of claim 8 , wherein the enhanced data is in an encrypted state when received by the sensor.

11. The method of claim 8 , 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.

12. The method of claim 8 , 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.

13. The method of claim 12 , wherein the collector comprises a personal computer, a tablet computer, or a mobile phone.

14. The method of claim 13 , wherein the sensor is a biosensor configured to determine a concentration of an analyte in a fluid sample.

15. The method of claim 8 , further comprising transmitting the enhanced data from the sensor to the collector according to the second communications protocol.

16. A sensor for diagnosing a physiological or physical state, comprising:
a measurement system configured to conduct a diagnostic analysis of a patient;
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 of the patient from the measurement system;
store the clinical data in a first memory area of the one or more memory devices wherein the clinical data includes a first set of one or more data fields;
transmit the clinical data to a collector according to a first one of the plurality of communications protocols, wherein the collector includes advanced processing functions to determine enhanced data based on processing the clinical data determined by the measurement system;
receive the enhanced data, based on the clinical data, from the collector according to a second one of the plurality of communications protocols having a set of rules for data exchange that are not publicly available, wherein the enhanced data includes information different from the clinical data and wherein the enhanced data includes the first set of one or more data fields and one or more additional data fields, including a recommended medication dosage based on the clinical data, and wherein the advanced processing functionality of the collector is omitted from the measurement system, and wherein the measurement system is not able to utilize the enhanced data; and
store only the enhanced data in a second memory area of the one or more memory devices.

17. The sensor of claim 16 , wherein the instructions further cause the computer-logic circuitry to delete the clinical data from the first memory area.

18. The sensor of claim 16 , wherein the clinical data is unencrypted and the enhanced data is encrypted.
