Abstract

Apparatus for communicating with a nurse call system is provided. The apparatus includes a hospital bed and a module spaced from the hospital bed. The hospital bed has a power cord including a first AC plug that plugs into an AC receptacle of the module. The module has a separate power cord that plugs into a standard AC power receptacle. Thus, power is provided to the hospital bed via the module. Bed data is communicated to the module via at least one conductor of the power cord that couples the bed to the module. The module has circuitry that extracts the bed data sent from the bed via the power cord and communicates the bed data to the nurse call system.

Claims

1. Apparatus for communicating with a nurse call system, the apparatus comprising

a hospital bed having a power cord including a first AC plug, the hospital bed having bed circuitry that sends bed data over at least one conductor of the power cord, and

a module spaced from the hospital bed, the module having a second AC plug that couples to a standard AC power receptacle in a room of a healthcare facility, a module AC power receptacle to which the first AC plug of the power cord of the hospital bed couples to receive power, module circuitry that is coupled to the at least one conductor of the power cord and that extracts the bed data, and an output device configured to couple the module circuitry to the nurse call system for transfer of the bed data from the module circuitry to the nurse call system.

2. The apparatus of claim 1, wherein the module circuitry comprises a low pass filter interposed between the second AC plug and the module AC power receptacle to block powerline communications from being communicated to the second plug.

3. The apparatus of claim 1, wherein the module circuitry includes isolation circuitry to isolate the bed data from being communicated to a power grid of a healthcare facility that delivers power to the standard AC power receptacle while permitting the bed data to be communicated to the nurse call system.

4. The apparatus of claim 1, wherein the output device comprises an outlet port.

5. The apparatus of claim 1, wherein the output device of the module comprises a communication cable.

6. The apparatus of claim 5, wherein the communication cable comprises a 37 pin connector.

7. The apparatus of claim 1, wherein the module includes at least one speaker.

8. The apparatus of claim 7, wherein the at least one speaker also serves as a microphone.

9. The apparatus of claim 7, wherein the at least one speaker is used for voice communication from the nurse call system.

10. The apparatus of claim 9, wherein the at least one speaker is also used for television sound.

11. The apparatus of claim 7, wherein the at least one speaker comprises a pair of speakers.

12. The apparatus of claim 11, wherein each speaker of the pair of speakers also serves as a microphone.

13. The apparatus of claim 1, wherein the bed data sent over the at least one conductor of the power cord comprises serial data.

14. The apparatus of claim 1, wherein data from the nurse call system is communicated to the bed circuitry via the module and the at least one conductor of the power cord such that the bed communicates bidirectionally over the power cord.

15. The apparatus of claim 1, wherein the bed data includes bed identification (ID) data and the module has module identification (ID) data associated therewith, the bed ID data and the module ID data is transmitted by the module to the nurse call system, and the nurse call system uses the bed ID data and module ID data to associate the hospital bed with the module.

16. The apparatus of claim 1, further comprising a pillow speaker unit in communication with the module circuitry.

17. The apparatus of claim 1, wherein the bed data comprises data pertaining to a position of one portion of a bed frame relative to another portion of the bed frame.

18. The apparatus of claim 1, wherein the bed data comprises data pertaining to a mattress function.

19. The apparatus of claim 1, wherein the bed data comprises data pertaining to a status of a bed exit alarm system of the hospital bed.

20. The apparatus of claim 1, wherein the bed data comprises patient physiologic data.
