1. A wireless medical device, the wireless medical device comprising:
- a processor;
a memory;
a sensor for detecting a physiological signal;
a radio; and
a proximity detector to measure a distance of the wireless medical device relative to a second wireless medical device, the proximity detector including a ranging functionality,wherein a wireless communication channel is created when the distance measured by the proximity detector between the wireless medical device and the second wireless medical device is within a first predetermined threshold, the distance being greater than zero,wherein, upon establishing the wireless communication channel, the wireless medical device receives a patient context from the second wireless medical device, the patient context providing an identifier for a patient;
wherein the patient context is transmitted from the second wireless medical device to the wireless medical device over a channel that is different from the wireless communication channel, with the channel using a different communication method from a primary communication method used for the wireless communication channel; and
wherein the patient context is removed from the wireless medical device when;
the distance between the wireless medical device and the second wireless medical device is greater than a second predetermined threshold for at least a predetermined time interval;
ora time since a physiological measurement has been made at the wireless medical device is greater than a predetermined time interval.

Abstract
A wireless medical device is disclosed. The wireless medical device comprises a processor, a memory, a sensor for detecting a physiological signal, a radio and a proximity detector to measure a distance of the wireless medical device relative to a second wireless medical device. The proximity detector includes a ranging functionality. A wireless communication channel is created when a distance between the wireless medical device and the second wireless medical device is within a first predetermined threshold. The distance is greater than zero.
