1. A data distribution system, comprising:
- a first personal area network (PAN) node, a second PAN node, and a PAN data blackboard coupled to the first and second PAN nodes via a PAN, wherein the PAN data blackboard comprises a first shared memory structure having a first data storage space, wherein the first PAN node comprises a first medical device configured for monitoring a first patient and writing patient medical data concerning the first patient to the first data storage space in real-time, and wherein the second PAN node comprises a second medical device configured for reading the patient medical data from the first data storage space and displaying the patient medical data in real-time;
a first local area network (LAN) node and a LAN data blackboard coupled to the first LAN node, wherein the LAN data blackboard is coupled to the PAN data blackboard via a LAN, wherein the LAN data blackboard comprises a second shared memory structure having a second data storage space, wherein the LAN data blackboard comprises a LAN data management node configured to determine that the first LAN node is entitled to access the patient medical data and to selectively synchronize data with the PAN data blackboard such that the patient medical data is stored in the second data storage space for retrieval in real-time by the first LAN node, and wherein the first LAN node comprises a third medical device configured for reading the patient medical data from the second data storage space and displaying the patient medical data in real-time; and
wherein the system is configured in accordance with a publish-subscribe messaging model in which nodes that are senders of messages (publishers) do not program the messages to be sent directly to specific receivers (subscribers) but instead categorize published messages into classes without knowledge of which subscribers, if any, there may be, and send the messages to an associated blackboard, andwherein each of the nodes is configured as a publisher or subscriber of data, or both a publisher and subscriber of data.

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.

12. A medical data monitoring and distribution method, comprising:
-
in a personal area network (PAN) comprising a first PAN node within a first medical device, a second PAN node within 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 a first data storage space of the PAN data blackboard in real-time, and employing the second PAN node and second medical device to read the patient medical data from the first data storage space and display the patient medical data in real-time; and in a local area network (LAN) comprising a first LAN node and a LAN data blackboard coupled to the PAN data blackboard via the LAN; determining, by a LAN data management node of the LAN data blackboard that the first LAN node is entitled to access the patient medical data, selectively synchronizing, by the LAN data management node, data with the PAN data blackboard such that the patient medical data is stored in a second data storage of the LAN data blackboard for retrieval in real-time by the first LAN node, reading, by the first LAN node, the patient medical data from the second data storage space, and displaying, by the first LAN node, the patient medical data in real-time, wherein the PAN and the LAN are configured in accordance with a publish-subscribe messaging model in which nodes that are senders of messages (publishers) do not program the messages to be sent directly to specific receivers (subscribers) but instead categorize published messages into classes without knowledge of which subscribers, if any, there may be, and send the messages to an associated blackboard, and wherein each of said nodes is configured as a publisher or subscriber of data, or both a publisher and subscriber of data. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
