## Abstract

A local hub maintains a secure and isolated connection with a device management server for reporting clinical data received from connected medical devices. Only authorized medical devices can communicate with the local hub and a list of allowed medical devices is managed by using a clinical application. A wearable device may be utilized to ensure that the user is within an acceptable range of the local hub.

## Claims

### Claim 1

A method of authenticating a plurality of medical devices for secure patient monitoring, the method comprising:
coupling the plurality of medical devices to a local hub;
sending, to the local hub, a first encrypted message via a first wireless communication method from a device management server, the first encrypted message comprising a payload;
extracting the payload from the first encrypted message at the local hub;
sending, from the local hub to the device management server, a second encrypted message containing the payload extracted from the first encrypted message by a second wireless communication method different than the first wireless communication method; and
extracting the payload from the second encrypted message at the device management server;
authenticating the local hub if the payload in the second encrypted message matches the payload in the first encrypted message.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
establishing a direct communication link between the local hub and the device management server; and
preventing communication with the local hub over the Internet from any device other than the device management server.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
transmitting a whitelist of approved medical devices from the plurality of medical devices to the local hub; and
preventing communication from any medical devices of the plurality of medical devices with the local hub for any medical devices not on the whitelist of approved medical devices.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
periodically sending a location of the local hub to the device management server; and
disconnecting the local hub if the location is not within one or more predetermined areas.

### Claim 5 (depends on 1)

The method of claim 1, wherein the first encrypted message comprises a short message service (SMS) message.

### Claim 6 (depends on 5)

The method of claim 5, wherein the second encrypted message comprise an Internet protocol (IP) message.

### Claim 7 (depends on 1)

The method of claim 1, wherein the local hub is authenticated by the device management server at random intervals.

### Claim 8 (depends on 1)

The method of claim 1, wherein the local hub is wiped if the local hub is not authenticated by the device management server after a predetermined number of tries.
