Abstract

A bed monitoring system that remotely monitors a patient bed. The bed monitoring system comprises a bed status system and a master station. The bed status system is coupled to the patient bed and is configured to monitor at least one condition of the bed, and to generate a bed message indicating the status of the monitored condition. The master station, remote from the patient bed, is operatively coupled to the bed status system to receive bed status information. The bed message can include a bed identifier, bed type identifier, patient exit detection signal, bed occupied signal, or various other status signals. The system can also include locating stations that receive the bed messages from any beds within its monitored location, and generates a station message including information from the bed messages. The master station receives the station messages and can determine the status and location of any bed.

12. The bed monitoring system of claim 1, wherein the master station includes a bed status indicator, the master station being configured to indicate the status of the monitored condition on the bed status indicator.

13. The bed monitoring system of claim 12, wherein the bed status indicator is a display device and the bed status information for the patient bed is viewable on the display device.

14. A bed monitoring system for locating a patient bed, including:

a bed signal generator coupled to the patient bed, the bed signal generator generating a bed status message including a bed identifier unique to the patient bed to which it is coupled;

a locating station located in each of a plurality of monitored locations, each locating station being configured to receive the bed status messages from any patient beds within the monitored location associated with the locating station, and to generate a station status message including information from the bed status messages and indicating the location of the locating station; and

a master station remote from the patient bed, the master station being operatively coupled to each of the locating stations to receive the station status messages generated by the locating stations;

wherein the master station processes the station status messages to determine the location of the patient bed.

15. The bed monitoring system of claim 14, further comprising a bed status system coupled to the patient bed, the bed status system configured to monitor a monitored condition of the patient bed, and the bed status message including the status of the monitored condition of the patient bed.
