Patent ID: 8907782

Claim:
A wireless medical device, the wireless medical device comprising: a processor; a memory that stores a patient context, the patient context providing an identifier for the patient; a radio comprising an ultra-wideband (UWB) transceiver that determines a distance between the wireless medical device and a second wireless medical device, the radio using the distance as part of an authentication process; wherein the wireless medical device is configured to join a personal area network with the second wireless medical device when the distance between the wireless medical device and the second wireless medical device is within a predetermined threshold, the distance being greater than zero, wherein the wireless medical device is configured to obtain the patient context from the second wireless medical device, the patient context being obtained from the second wireless medical device when the distance between the wireless medical device and the second wireless medical device is within the predetermined threshold for at least a predetermined interval of time, wherein the wireless medical device is configured to transfer physiological data to the second wireless medical device, the physiological data being transferred along with the patient context, and wherein the wireless medical device is configured to support a spot check mode and a continuous workflow mode, wherein when a second distance determined by the radio between the wireless medical device and the second wireless monitor device is greater than a second predetermined threshold for at least a second predetermined interval of time, the patient context data is removed from the wireless medical device if the wireless medical device is operating in a spot check mode and the patient context data remains stored on the wireless medical device if the wireless medical device is operating in a continuous workflow mode.
