Abstract

A method for automatically adding a first sensor device to a first personal area network in a healthcare application includes receiving a signal with out-of-band pairing data at the first sensor device. The first sensor device is disposed on a patient'"'"'s body. The out-of-band pairing data is injected into the patient'"'"'s body by a second sensor device disposed on the patient'"'"'s body. Pairing data is extracted from the received signal at the first sensor device. Using the pairing data, the first sensor device is added to the first personal area.

Claims

1. A method for automatically identifying a patient in a healthcare application, the method comprising:

attaching a wristband to a patient, the wristband adapted to provide out-of-band pairing data;

coupling a sensor device to the wristband, the sensor device detecting the out-of-band pairing data;

attaching the sensor device to the patient'"'"'s body;

detecting a personal area network that uses the detected out-of-band pairing data; and

joining the personal area network that uses the detected out-of-band pairing data.

2. The method of claim 1, further comprising the wristband adapted to provide a patient identifier.

3. The method of claim 2, further comprising the sensor device transmitting the patient identifier and sensor data to the personal area network.

4. A method for detecting and displaying the names of patients proximal to a detector, the method comprising:

providing to a user a detecting device for discovering one or more personal area networks, each of the one or more personal area networks having a unique network identifier;

discovering, at the detecting device, one or more personal area networks;

obtaining the network identifier for each of the one or more personal area networks that are discovered at the detecting device;

for each obtained network identifier, obtaining one or more patient identifiers that are uniquely associated with the obtained network identifier; and

displaying a list of the obtained patient identifiers.

5. The method of claim 4, wherein the detecting device discovers the one more personal area networks via a gateway on each of the one more personal area networks.

6. The method of claim 5, wherein the detecting device obtains the one or more patient identifiers from a server computer that is accessible to each gateway.
