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,

a third data interface for receiving an access request to the patient data from a portable communications device,

a 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,

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,

a second communication interface for receiving the patient data, and

a processor for generating the access request,

wherein the third data interface includes a first communication channel that is different than a second communication channel used by the second data interface.

2. The system of claim 1, wherein the access request includes an access code.

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

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

5. The system of claim 3, wherein the secret includes an ephemeral secret.

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

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

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

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

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

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