Abstract

An apparatus for providing data communication and power to a device located in a room having a power outlet is disclosed. The power outlet may be a standard AC outlet, for example. The apparatus includes a cable extending from the device and having a plug comprising a plug body. Prongs extend from the plug body and couple to the power outlet to receive power. A first near field communication antenna is carried by the plug body. A communication module has a second near field communication antenna and is located in the room in proximity to the plug. At least one of the first near field communication antenna and the second near field communication antenna communicates data wirelessly to the other of the first near field communication antenna and the second near field communication antenna.

Claims

1. A system comprising

a bed having an auxiliary power outlet,

a medical device including a cable having at one end thereof a plug comprising a plug body, a plurality of prongs extending from the plug body and configured to couple to the auxiliary power outlet to receive power,

a first near field communication antenna carried by the plug body,

a communication module comprising a second near field communication antenna, the communication module being coupled to the bed in proximity to the auxiliary power outlet, at least one of the first near field communication antenna and the second near field communication antenna communicating data wirelessly to the other of the first near field communication antenna and the second near field communication antenna, and

first near field communication circuitry carried by the medical device and coupled to the first near field communication antenna via at least one conductor routed along the cable, wherein the bed receives data from the medical device via the first and second near field communication antennae.

2. The system of claim 1, wherein the bed includes second near field communication circuitry that receives data from the medical device via the first and second near field communication antennae.

3. The system of claim 2, wherein the bed is configured to send at least some of the data received from the medical device to a unit spaced from the bed.

4. The system of claim 3, wherein the bed has a third near field communication antenna and the unit spaced from the bed has a fourth near field communication antenna, the at least some of the data sent by the bed is transmitted from the third near field communication antenna to the fourth near field communication antenna.

5. The system of claim 1, wherein the first near field communication antenna serves as a passive target and the second near field communication antenna is included as part of an initiator circuit that actively generates a radio frequency field via the second near field communication antenna to power up the passive target for data transfer.

6. The system of claim 1, wherein the second near field communication antenna serves as a passive target and the first near field communication antenna included as part of an initiator circuit that actively generates a radio frequency field via the first near field communication antenna to power up the passive target for data transfer.

7. The system of claim 1, wherein the communication module has an opening through which the auxiliary power outlet is accessible.

8. The system of claim 1, further comprising second near field communication circuitry coupled to the second near field communication antenna, the first and second near field communication circuitry communicating via the first near field communication antenna and the second near field communication antenna according to a peer-to-peer protocol.

9. The system of claim 1, further comprising a read/write module coupled to the first near field communication antenna.

10. The system of claim 1, further comprising a read/write module coupled to the second near field communication antenna.

11. The system of claim 1, wherein the medical device comprises at least one of the following:

an IV pumps, a blood pressure monitor, an electrocardiograph (EKG), an electroencephalograph (EEG), a pulse oximeter, a ventilator, a respiration monitor, or a temperature monitors.

12. The system of claim 1, wherein the bed is configured to verify whether the medical device plugged into the auxiliary power outlet is an authorized medical device based on information transmitted from the first near field communication to the second near field communication antenna.

13. The system of claim 12, wherein the bed includes an indicator to provide an alert if an inappropriate medical device is plugged into the auxiliary power outlet.

14. The system of claim 12, wherein the bed transmits an alert message to a network if an inappropriate medical device is plugged into the auxiliary power outlet.

15. The system of claim 12, wherein the authorized medical device comprises critical care equipment for a patient.

16. The system of claim 1, wherein the bed transmits patient weight information to the medical device via the first and second near field communication antennae and the medical device uses the weight information to establish an operating parameter.

17. The system of claim 1, wherein the bed includes Wi-Fi circuitry and data received from the medical device via the first and second near field communication antennae is transmitted from the bed wirelessly by the Wi-Fi circuitry.

18. The system of claim 1, wherein the bed has a third near field communication antenna and further comprising a unit that is spaced from the bed and that has a fourth near field communication antenna, the bed configures itself based on a location ID that is transmitted to the bed via the third and fourth near field communication antennae.

19. The system of claim 1, wherein the bed has a third near field communication antenna and further comprising a unit that is spaced from the bed and that has a fourth near field communication antenna, the bed configures itself based on a patient ID that is transmitted to the bed via the third and fourth near field communication antennae.

20. The system of claim 1, wherein the first near field communication antenna is included in a label that sticks to the plug body.
