Abstract

A communication system is used by a portable patient monitoring device for connecting to other devices, including a docking station, via one or more networks. The communications system includes an adaptive communication interface which, when the patient monitoring device is docked, establishes communication with a first network, and receives from a first docking station a first unique identifier that identifies the first docking station, allowing the patient monitoring device to communicate patient parameters to the first destination. While the portable patient monitoring device is undocked, the adaptive communication interface is inhibited from establishing communication with a network providing an identifier to the portable patient monitor that does not match the first unique identifier. Upon docking to a second docking station, the patient monitoring device establishes communication with a second network using a new unique identifier received from the second docking station via a second exclusive communication link.

Claims

1. communication system configured to connect a portable patient monitoring device to a plurality of networks via separate communication links, comprising:

a first network comprising a first docking station and a first destination;

a second network comprising a second docking station and a second destination;

a portable patient monitoring device comprising an adaptive communication interface which automatically

establishes communication with the first network, in response to detecting that the portable patient monitoring device is docked to the first docking station, and receives from the first docking station via a first exclusive communication link between the first docking station and the portable patient monitoring device a first unique identifier that identifies the first docking station, and communicates patient parameters to the first destination,

maintains communication with the first network, in response to detecting that the portable patient monitoring device is undocked from the first docking station and the first exclusive communication link is unavailable and receiving the first unique identifier from the first network via a first wireless communication link between the portable patient monitoring device and the first network, and communicates patient parameters via said first wireless communication link to the first destination;

wherein the adaptive communication interface is inhibited, while the portable patient monitoring device is undocked, from establishing communication with a network providing an identifier to the portable patient monitoring device that does not match the first unique identifier, and

establishes communication with the second network, in response to detecting that the portable patient monitoring device is docked to the second docking station, and receives from the second docking station via a second exclusive communication link between the second docking station and the portable patient monitoring device a second unique identifier that identifies the second docking station, and communicates patient parameters to the second destination.

2. The communication system of claim 1, wherein the first destination is different from the second destination.

3. The communication system of claim 1, wherein the first destination is identical to the second destination.

4. The communication system of claim 1, wherein the unique identifier identifies messages to and from at least one of the first and second network.

5. The communication system of claim 1, wherein the unique identifier identifies a geographic location of at least one of the first and second docking station.

6. The communication system of claim 1, wherein the unique identifier is part of a message sent from the portable patient monitoring device and identifies the first or second network which sent the message.

7. A method for connecting a portable patient monitoring device to a plurality of networks via separate communication links, comprising the steps of:

the portable patient monitoring device, in response to detecting that the portable patient monitoring device is docked to a first docking station associated with a first network defining a first destination, establishing communication with the first network and receiving from the first docking station via a first exclusive communication link between the first docking station and the portable patient monitoring device a first unique identifier that identifies the first docking station, and communicates patient parameters to the first destination,

the portable patient monitoring device, in response to detecting that the portable patient monitoring device is undocked from the first docking station and the first exclusive communication link is unavailable and receiving the first unique identifier from the first network via a first wireless communication link between the portable patient monitoring device and the first network, maintains communication with the first network, in response to detecting and communicates patient parameters via said first wireless communication link to the first destination;

wherein the portable patient monitoring device is inhibited, while the portable patient monitoring device is undocked, from establishing communication with a network providing an identifier to the portable patient monitoring device that does not match the first unique identifier, and

the portable patient monitoring device, in response to detecting that the portable patient monitoring device is docked to a second docking station associated with a second network defining a second destination, establishing communication with a second network and receiving from the second docking station via a second exclusive communication link between the second docking station and the portable patient monitoring device a second unique identifier that identifies the second docking station, and communicating patient parameters to the second destination.

8. The method of claim 7, wherein the first destination is different from the second destination.

9. The method of claim 7, wherein the first destination is identical to the second destination.

10. The method of claim 7, wherein the unique identifier identifies messages to and from at least one of the first and second network.

11. The method of claim 7, wherein the unique identifier identifies a geographic location of at least one of the first and second docking station.

12. The method of claim 7, wherein the unique identifier is part of a message sent from the portable patient monitoring device and identifies the first or second network which sent the message.
