System and apparatus for electronic patient care

A system for electronic patient care, the system comprising:

• a network;
• a facility gateway configured to provide a publish-subscribe service;
• a device gateway application configured for execution by the facility gateway, the device gateway is configured to communicate via the network by providing a web service, wherein the device gateway publishes a medical device event topic;
• a device application configured for execution on the facility gateway and configured to subscribe to the medical device event topic, wherein the device application publishes a Continuous Quality Improvement (“CQI”)-message topic, and wherein the device application is configured to receive an event from the subscription to the medical device event topic and publish the event as a CQI message through the CQI-message topic;
• a medical device in operative communication with the network, wherein:
• only the medical device is configured to communicate with the device gateway using the web service and to generate the event using a web method of the web service,
• the medical device initiates communications with the device gateway using the web service at predetermined intervals of time to request a response payload, the device gateway configured to be prevented from initiating communications with the medical device;
• the device gateway determines whether the medical device is listed on an access list of medical devices that can access the device gateway;
• in response to the medical device initiated communication by the medical device determined to be on the access list, the device gateway formats the response payload comprising an availability of a software update, an availability of a queryable data type, and a plurality of current request statuses, wherein each current request status is a request for the medical device to transmit a data type of a plurality of data types to the device gateway,
• the device gateway communicates the response payload to the medical device in response to the medical device initiated communication, and
• the medical device communicates all data types of the plurality of data types where a respective current request status of the current request statutes indicates a request of a respective data type;
• and
• a publish-subscribe engine configured to provide the publish-subscribe service for communication between a plurality of applications including the device gateway application and the device application, the plurality of applications being executed within the facility gateway.
