Abstract

A patient monitoring system that enables a healthcare provide to request access to patient data via interaction directly with a local patient monitor and subsequently provide patient data to the healthcare provider'"'"'s portable communication device regardless of device location.

Claims

1. A patient monitoring system comprising:

a patient monitoring device for monitoring a physical condition of a patient, the patient monitoring device including;

a first data interface for receiving physiological data from a patient sensor,

a second data interface for sending patient data to a patient monitoring network via a first communication channel and for receiving, from a central station, authorization information for authorizing an access request to the patient data by a portable communications device, and

a third data interface for receiving the access request to the patient data from the portable communications device via a second communication channel, wherein the access request includes an access code,

the central station being located remotely from the patient monitoring device and in communication with the patient monitoring network, the central station storing access control data associated with the patient monitoring device for authorizing the access request to the patient data by the portable communications device,

the portable communications device including;

a user interface for displaying a patient physical condition based on patient data received from the patient monitoring device,

a first communication interface for sending the access request to the patient monitoring device via the second communication channel, wherein the first communication interface is configured to communicate when within a close proximity of the patient monitoring device using a personal area network,

a second communication interface for receiving the patient data, wherein the second communication interface is configured to communicate using a wide area network and

a processor for generating the access request,

wherein the first communication channel is different than the second communication channel, and

wherein a range of the second communication interface exceeds a range of the first communication interface.

2. The system of claim 1, wherein the access code is derived from a secret.

3. The system of claim 2, wherein the access code includes a cryptographic response to a challenge.

4. The system of claim 2, wherein the secret includes an ephemeral secret.

5. The system of claim 1, wherein the patient monitoring device grants access to the patent data based on whether the access code is acceptable.

6. The system of claim 5, wherein the access code is determined to be acceptable by comparing the access code with a stored access code.

7. The system of claim 1, wherein the first communication channel includes a first wireless channel.

8. The system of claim 7, wherein the first wireless channel is limited in range.

9. The system of claim 8, wherein the portable communications device is in relatively close proximity to the patient monitoring device.

10. The system of claim 1, wherein the portable communications device includes a handheld device.

11. The patient monitoring device of claim 1, wherein the authorization information includes an authorization code.
