System and Method For Collection and Communication of Data From Multiple Patient Care Devices

A method of associating a plurality of devices in a room with either a first patient in the room or a second patient in the room, the method comprising

• providing time of flight or time of arrival data to an association computer, the association computer being operable to determine a distance to each device of the plurality of devices from a first reference point associated with the first patient and from a second reference point associated with the second patient based on the time of flight or time of arrival data,
• as among two like devices in the room, associating the like device that is closest to the first reference point with the first patient and associating a second of the like devices that is closest to the second reference point with the second patient,
• obtaining data via an Ethernet of a healthcare facility from a remote computer, and
• resolving ambiguities as to whether at least one device of the plurality of devices is associated with the first patient or the second patient based on the data obtained from the remote computer.
