ABSTRACT:
A communications system and protocol are described for wirelessly interconnecting a pair of bed and wall units that communicate the patient information, including bed exit alerts, from the patient supporting equipment to the hospital nurse call system. A linking procedure is provided for establishing a communications link to interconnect the pair of units, wherein the communications link fails upon detection of a third communications device simultaneously undergoing the link attempt mode. In one embodiment, the system provides for advanced collision detection by monitoring corruption of the end-of-packet byte within the periodic check-in message sequences between the linked units to prevent data corruption and future collisions. To ensure prompt interconnection of units, embodiments of the invention provide for a link reminder to alert the health care provider to initiate the steps for linking the bed and wall units whenever two or more unlinked units are in proximity.
