Abstract

A method and system is provided for management of medical data from a network of devices. The network of devices may include federated sensors that collect and forward medical data pertaining to an individual or biological specimen. The federated sensors or a central or remote device may further process the medical data and assign a priority value to the medical data. Processing can also include the analysis of the data for sensor error, local fusion of multiple sensors into higher-level interpretations, and the summarization or abstraction of the data into information that people are more comfortable with sharing than they might be with transmittal of the base data. The medical data may be transported to a healthcare provider or other endpoints based on the priority value and the authorization of recipient.

Claims

1. A method for providing data from a network of sensors sensing medical data, the method comprising:

receiving medical data from the sensors;

generating a priority value for the received medical data including;

determining a type of the received medical data;

assigning a priority value to the received medical data based on the type;

comparing the received medical data with an expected corresponding normal value; and

assigning the priority value based on the comparing step including;

assigning a first priority value to the received medical data if the received medical data is within an expected range of normal values, otherwise assigning a second priority value, the second priority value being higher than the first priority value;

assigning the second priority value to the received medical data if the received medical data is outside the expected range of normal values but within a predetermined range of values, otherwise assigning a third party priority value, the third priority value being higher that the second priority value;

transporting the medical data to a healthcare provider according to the priority values; and

comparing the priority value of the received medical data to the priority values of other received medical data and transporting the received medical data to the healthcare provider if the priority value of the received medical data is greater than or equal to the priority values of the other received medical data,

wherein the priority value of at least one other received medical data is greater than the priority value of the received medical data, the method further comprising transporting the at least one other received medical data substantially simultaneously with the received medical data and wherein the at least one other received medical data is transported with an indicator, the indicator indicating that the at least one other received medical data has priority.

2. The method of claim 1 wherein the predetermined range of values comprises values within a predetermined percentage of the expected range of normal values.

3. The method of claim 1 wherein the step of assigning the priority value based on the comparing step includes assigning the third priority value to the received medical data and the step of transporting includes transporting the received medical data to an emergency service based on the assigning.

4. The method of claim 1 further comprising transporting other received medical data having a priority value greater than the received medical data prior to transporting the received medical data to the healthcare provider.

5. The method of claim 1 wherein the indicator includes a position in a list.

6. The method of claim 1 further comprising:

sorting the received medical data and the other received medical data based on corresponding priority values; and

generating a list of medical data in order of priority values,

wherein the step of transporting includes transporting the list of medical data to the healthcare provider.

7. The method of claim 1 wherein the step of assigning the priority value based on the comparing step includes:

assigning the first priority value to the received medical data; and

comparing the priority value of the received medical data to the priority values of other received medical data and transporting the received medical data to the healthcare provider if the priority value of the received medical data is greater than or equal to the priority values of the other received medical data.

8. The method of claim 7 further comprising transporting other received medical data having a priority value greater than the received medical data prior to transporting the received medical data to the healthcare provider.

9. The method of claim 7 further comprising batching the received medical data with other medical data having a priority value about equal to the first priority value.

10. The method of claim 1 wherein the step of transporting includes filtering the medical data based on the priority value, wherein the filtered medical data is not transported to the healthcare provider.

11. The method of claim 1 further comprising:

comparing the received medical data with previously received medical data corresponding to a subject; and

assigning a relevance value to the received medical data based on the comparing step,

wherein generating the priority value includes generating the priority value based on the relevance value.

12. The method of claim 11 wherein the comparing includes identifying a difference between the received medical data and the previously received medical data, the identified difference including a trend associated with a change of the received medical data from the previously received medical data.

13. The method of claim 12 wherein the trend indicates pathophysiology of the subject.

14. The method of claim 12 wherein the trend includes one of an increase or a decrease of a value corresponding to the received medical data, the trend corresponding to a likelihood of pathophysiology in the subject.

15. The method of claim 14 further comprising measuring the trend over a period of time, wherein generating the priority value further includes generating the priority value based on the trend over the period of time.

16. A method for providing data from a network of sensors sensing medical data, the method comprising:

receiving medical data from the sensors;

generating a priority value for the received medical data; and

transporting the medical data to a healthcare provider according to the priority values;

receiving input from a subject, the input comprising a preference for data privacy;

identifying at least a portion of the received medical data as private based on the preference; and

filtering the identified at least a portion of the received data,

wherein the transporting includes transporting a portion of the received medical data not filtered.

17. The method of claim 16 wherein filtering includes summarizing the filtered identified data and wherein the transporting further includes transporting the summarized filtered identified data.

18. The method of claim 17 wherein filtering includes forming a composite of the identified at least a portion of the received data and wherein the transporting further includes transporting the composite data.

19. The method of claim 16 further comprising:

receiving input from a healthcare provider, the input including a request for access to the identified at least a portion of the received data;

transporting the identified at least a portion of the received data based on the request.

20. The method of claim 19 wherein the input includes an authenticator for verifying the healthcare provider.

21. A method for identifying healthcare data sensors in a sensor device network, the method comprising:

receiving medical data from a plurality of sensor devices;

identifying a type of medical data from each of the sensor devices in the plurality of sensor devices;

comparing matching types of medical data from each corresponding sensor device in the plurality of sensor devices;

assigning a reliability factor to sensor devices based on the comparing;

transporting the medical data including the assigned reliability factor,

wherein the comparing includes identifying a first sensor device in the plurality of sensor devices, wherein the first sensor device provides medical data that is substantially different from the medical data from each corresponding sensor device in the plurality of sensor devices and wherein the assigning comprises assigning a first reliability factor to the first sensor device and a second reliability factor to each corresponding sensor device in the plurality of sensor devices, wherein the first reliability factor is different from the second reliability factor.

22. The method of claim 21 wherein the first reliability factor indicates a predicted accuracy level of the medical data from the first sensor device.
