Abstract

Access to a medical monitoring system, which includes a patient-portable monitoring device and an associated monitoring service at a central unit, is controlled by inputting a set of identification data elements into a medical monitoring device, which then establishes a communication link with a central unit and communicates the set of identification data elements to the central unit. The medical monitoring device and the central unit cooperatively determine whether the medical monitoring device may be activated for rendering medical monitoring device service, by evaluating the set of identification data elements as to whether they meet a set of basic structural requirements, and obtaining financial or other authorization from a third-party source. In the event that the identification data elements meet the set of basic structural requirements and the authorization is obtained, the central unit issues an activation signal to the medical monitoring device over the communication link.

Claims

1. A computer-based method for controlling access to a medical monitoring system, the method comprising:

receiving information indicating that a remote monitoring device seeks access to a monitoring service hosted by a central unit, the remote monitoring device comprising a patient-portable device configured to monitor one or more physiological aspects of a patient;

determining whether the remote monitoring device is authorized to access the monitoring service, the determination being based at least in part on authorization data received from a third-party source; and

based on a result of the determination, selectively issuing an activation signal to the remote monitoring device.

2. The method of claim 1 wherein the determination of whether the remote monitoring device is authorized to access the monitoring service is performed cooperatively between the remote device and the central unit.

3. The method of claim 1 wherein the determination of whether the remote monitoring device is authorized to access the monitoring service comprises one or both of (i) performing a format check on access data entered into the remote monitoring device and (ii) comparing the entered access data against the third-party authorization data.

4. The method of claim 1 further comprising maintaining at the central unit a local database of third-party authorization data to be used in the determination of whether the remote monitoring device is authorized to access the monitoring service.

5. The method of claim 4 further comprising updating the local third-party authorization database.

6. The method of claim 5 wherein updating of the local third-party authorization database occurs periodically or based on a predetermined event or a combination of both.

7. The method of claim 1 wherein selectively issuing the activation signal to the remote monitoring device based on a result of the determination comprises issuing the activation signal if the remote monitoring device is determined to be authorized to access the medical monitoring service and refraining from issuing an activation signal if the remote monitoring device is determined to be unauthorized to access the medical monitoring service.

8. The method of claim 1 wherein the remote monitoring device communicates with the central unit through one or more communications links including either or both of a wired communication link and a wireless communication link.

9. A medical monitoring system centered at a central node, the medical monitoring system comprising:

one or more communications links configured to facilitate communications with a plurality of patient-portable remote monitoring devices and one or more third-party authorization sources, the remote monitoring devices being configured to monitor one or more physiological aspects of a patient;

at least one programmable processor configured to perform operations comprising;

host a medical monitoring service, the medical monitoring service being implemented at least in part by one or more software processes;

receive information indicating that a remote monitoring device seeks access to the medical monitoring service;

determine, based at least in part on authorization data received from a third-party authorization source, whether the remote monitoring device is authorized to access the monitoring service; and

based on a result of the determination, selectively issue an activation signal to the remote monitoring device.

10. The system of claim 9 wherein the programmable processor is further configured to maintain at the central node a local database of third-party authorization data to be used in the determination of whether the remote monitoring device is authorized to access the monitoring service.

11. The system of claim 9 further comprising a local database of third-party authorization data and wherein the programmable processor further is configured to update the local authorization database based on data received from the one or more third-party authorization sources.

12. The system of claim 11 wherein the programmable processor is further configured to determine whether the remote monitoring device is authorized to access the monitoring service by one or both of (i) performing a format check on access data entered into the remote monitoring device and (ii) comparing the entered access data against the third-party authorization data.

13. The system of claim 11 wherein the programmable processor updates the local authorization database periodically or based on a predetermined event or a combination of both.

14. The system of claim 9 wherein the programmable processor issues the activation signal to the remote monitoring device if the remote monitoring device is determined to be authorized to access the medical monitoring service and refrains from issuing an activation signal if the remote monitoring device is determined to be unauthorized to access the medical monitoring service.

15. A portable medical monitoring device configured to monitor one or more physiological aspects of a patient, the device comprising:

a transceiver for communicating with a central unit;

a user interface for communicating with a user of the device; and

a programmable processor configured to perform operations comprising;

receive user input specifying user-specific information;

transmit the received user input to the central unit for third-party authorization based at least in part on the user-specific information; and

selectively provide the user with access to a monitoring service hosted at the central unit based on a result of the third-party authorization.

16. The device of claim 15 wherein the programmable processor further is configured to perform a format check on the received user input to determine whether the user input meets one or more predetermined criteria.

17. The device of claim 16 wherein the programmable processor is further configured to refrain from transmitting the received user input to the central station if the user input is determined not to meet one or more of the predetermined criteria.

18. The device of claim 17 wherein the programmable processor is further configured to deny access to the monitoring service if the user input is determined not to meet one or more of the predetermined criteria.

19. The device of claim 15 wherein the programmable processor provides access to the monitoring service if the device receives an activation signal from the central unit and denies access to the monitoring service if the device fails to receive an activation signal from the central unit.

20. A computer-based method for controlling access to a medical monitoring system, the method comprising:

receiving information indicating that a patient-portable remote monitoring device seeks access to a monitoring service hosted by a central unit, the patient-portable remote monitoring device configured to monitor one or more physiological aspects of a patient;

determining whether the patient-portable remote monitoring device is authorized to access the monitoring service, the determination being based at least in part on authorization data received from a third-party source; and

based on a result of the determination, selectively issuing an activation signal to the patient-portable remote monitoring device.

21. A medical monitoring system centered at a central node, the medical monitoring system comprising:

one or more communications links configured to facilitate communications with a plurality of patient-portable remote monitoring devices and one or more third-party authorization sources, the patient-portable remote monitoring devices being configured to monitor one or more physiological aspects of a patient;
