Abstract

A data distribution system in comprises software application nodes that utilize a publish-subscribe communication mechanism for distribution of data in real-time or near real-time within a personal area network (PAN), local area network (LAN), or wide-area network (WAN) configuration. The distributed system communication software application nodes reside in medical devices, such as monitoring devices and cardiac defibrillators, and associated patient information delivery systems and patient data management systems comprising medical software installed on servers and end-user computing devices, including mobile devices.

Claims

1. A data distribution system, comprising:

a personal area network (PAN) (110) comprising a first PAN node (112) and a second PAN node (113), and a PAN data blackboard (116) coupled to the first and second PAN nodes, wherein the first PAN node comprises a first medical device configured for monitoring a first patient;

wherein the PAN data blackboard is configured to provide a data storage space shared among the first and second PAN nodes.

2. The data distribution system recited in claim 1, further comprising a wide area network (WAN) (130) comprising a WAN data blackboard (131a) coupled to the PAN data blackboard, and a WAN data management node (133) coupled to the WAN data blackboard;

and wherein the first PAN node is configured as publisher node, whereby the first PAN node writes data to the PAN data blackboard; and

the second PAN node is configured as a subscriber node, whereby the second PAN node reads data from the PAN data blackboard.

3. The data distribution system recited in claim 2, further comprising a local area network (LAN) (120), the LAN comprising:

a first LAN node (122);

a second LAN node (123);

a LAN data blackboard (126) coupled to the first and second LAN nodes and to the WAN data blackboard (via Bridge); and

a LAN data management node (128) coupled to the LAN data blackboard.

4. The data distribution system recited in claim 3, wherein the first LAN node comprises a second medical device configured for monitoring a second patient and providing measured patient data to the LAN data blackboard;

wherein the LAN data blackboard is configured to provide a data storage space shared among the first and second LAN nodes;

wherein the first LAN node is configured as publisher node, whereby the first LAN node writes data to the LAN data blackboard; and

wherein the second LAN node is configured as a subscriber node, whereby the second LAN node reads data from the LAN data blackboard.

5. The data distribution system recited in claim 4, further comprising a first WAN node (132) and a second WAN node (134, 135).

6. The data distribution system recited in claim 5, wherein the WAN data blackboard is configured to provide a data storage space shared among the first and second WAN nodes;

wherein the first WAN node is configured as publisher node, whereby the first WAN node writes data to the WAN data blackboard; and

wherein the second WAN node is configured as a subscriber node, whereby the second WAN node reads data from the WAN data blackboard.

7. The data distribution system recited in claim 6, wherein the first PAN node comprises a first software application node residing in the first medical device, and the second PAN node comprises a second software application node residing in the second medical device.

8. The data distribution system recited in claim 7, wherein the first LAN node comprises a third software application node residing in a third medical device, and the second PAN node comprises a forth software application node residing in fourth medical device.

9. The data distribution system recited in claim 8, wherein the first WAN node comprises a fifth software application node residing in a fifth medical device configured for monitoring a third patient, and wherein the second WAN node comprises a sixth software application node residing in a display device.

10. The data distribution system recited in claim 9, wherein at least one of the first, second, third, fourth, or fifth medical devices is a cardiac defibrillator or cardiac monitoring device.

11. A medical data monitoring and distribution method, comprising:

in a personal area network (PAN) comprising a first PAN node within a first medical device and a second PAN node in a second medical device, and a PAN data blackboard, employing the first PAN node and first medical device to monitor a first patient and to write medical data concerning the first patient to the PAN data blackboard; and

in a wide area network (WAN) comprising a WAN data blackboard coupled to the PAN data blackboard, using the WAN data blackboard to read said data concerning the first patient from the PAN data blackboard.

12. The medical data monitoring and distribution method recited in claim 11, wherein the first PAN node writes data to the PAN data blackboard;

and the second PAN node reads data from the PAN data blackboard.

13. The medical data monitoring and distribution method recited in claim 12, further comprising coupling a local area network (LAN) to the WAN, wherein the LAN comprises a first LAN node, a second LAN node, a LAN data blackboard, and a LAN data management node.

14. The medical data monitoring and distribution method recited in claim 13, wherein the first LAN node comprises a second medical device configured for monitoring a second patient and providing measured patient data to the LAN data blackboard;

wherein the first LAN node writes data to the LAN data blackboard; and

wherein the second LAN node reads data from the LAN data blackboard.

15. The medical data monitoring and distribution method recited in claim 14, further comprising coupling a first WAN node and a second WAN node to the WAN data blackboard.

16. The medical data monitoring and distribution method recited in claim 15, wherein the WAN data blackboard is configured to provide a data storage space shared among the first and second WAN nodes;

wherein the first WAN node writes data to the WAN data blackboard; and

wherein the second WAN node reads data from the WAN data blackboard.

17. The medical data monitoring and distribution method recited in claim 16, wherein the first PAN node comprises a first software application node residing in the first medical device, and the second PAN node comprises a second software application node residing in the second medical device.

18. The medical data monitoring and distribution method recited in claim 17, wherein the first LAN node comprises a third software application node residing in a third medical device, and the second PAN node comprises a forth software application node residing in fourth medical device.

19. The medical data monitoring and distribution method recited in claim 18, wherein the first WAN node comprises a fifth software application node residing in a fifth medical device configured for monitoring a third patient, and wherein the second WAN node comprises a sixth software application node residing in a display device.

20. The medical data monitoring and distribution method recited in claim 19, wherein at least one of the first, second, third, fourth, or fifth medical devices is a cardiac defibrillator or cardiac monitoring device.
