Abstract

A patient monitoring system for remote monitoring of medical devices. The system includes a medical device, a patient identification device and a wireless relay module. The relay module receives patient identification information from the patient identification device and medical device identification from the medical device via a wireless relay network, and transmits this information to the remote monitoring device via an internet-accessible wireless communications network. The remote monitoring device returns an acknowledgement status to the relay module, which the relay module transmits to the medical device. Upon receipt of an acknowledgment status indicating that the patient'"'"'s use of the medical device is authorized, the medical device transmits medical device data to the relay module via the wireless relay network, and the relay module relays the medical device data to the remote monitoring device via the internet-accessible wireless communications network.

Claims

1. A patient monitoring system configured for providing communications between medical devices used by patients and a remote monitoring device via an internet-accessible wireless communications network, said system comprising:

a medical device to be used by a patient;

a patient identification device capable of receiving an input indicative of patient identification information of the patient and of transmitting the patient identification information; and

at least one relay module comprising;

a first receiver capable of wirelessly receiving data over a wireless relay network;

a second receiver capable of wirelessly receiving data over the internet-accessible wireless communications network a first transmitter capable of wirelessly transmitting the received data to a wireless relay module over the wireless relay network;

a second transmitter capable of wirelessly transmitting the received data over an internet-accessible wireless communications network to the remote monitoring device; and

a controller coupled to the first and second transmitters, wherein;

one or more of the patient identification device and the medical device are capable of transmitting patient identification data and medical device identification data to the at least one relay module over the wireless relay network, said controller of said at least one relay module is configured to select one of said first transmitter or said second transmitter for transmitting the identification information to the remote monitoring device, said at least one relay module being further configured to receive an acknowledgement status transmitted by the remote monitoring device at one of said first and second receivers, and to transmit the acknowledgement status by said first transmitter to the medical device over the wireless relay network, and the medical device being further configured to receive the acknowledgement status and transmit medical device data corresponding to an output of at least one sensor of the medical device to the at least one relay module via the wireless relay network when the received acknowledgement status represents a particular status.

2. The system of claim 1, wherein the acknowledgment status is received in a first form at one of said first or second receivers of the at least one relay module, and is transmitted in a second form by said first transmitter of the at least one relay module to the medical device.

3. The system of claim 2, wherein said controller is capable of determining a status of said internet-accessible wireless communications network and of selecting one of said first or second transmitter for transmitting said received data based on said status.

4. The system of claim 2, wherein said controller is configured to transmit said received information via the internet-accessible wireless communications network by said second transmitter if said status satisfies a particular criteria;

and

is configured to transmit said received information by said first transmitter in communication with said wireless relay network if said status fails to satisfy said particular criteria.

5. The system of claim 2, wherein said at least one relay module further comprises:

a memory electrically connected to said controller, said memory capable of buffering operating instructions from said remote monitoring device at one of said first and second receivers and said controller capable of controlling at least one of the order and or the priority for transmission of said buffered operating instructions by said first transmitter to the medical device, wherein said at least one relay module is further capable of outputting warnings or error messages concerning a current availability of one or more of the wireless relay network and the internet-accessible wireless communications network.

6. The system of claim 1, wherein said second transmitter is further capable of transmitting operating instructions to said at least one medical device.

7. The system of claim 1, wherein said wireless relay network is a ZIGBEE network.

8. The system of claim 1, wherein said internet-accessible wireless communications network is a mobile communications network.

9. The system of claim 8, wherein said mobile communications network is a CDMA or GSM-based network.

10. The system of claim 1, wherein one or more of the patient identification device and the medical device comprises:

a third transmitter capable of wirelessly transmitting said medical device data over said wireless relay network.

11. The system of claim 1, wherein one or more of the patient identification device and the medical device comprises:

a third receiver capable of wirelessly receiving instructions over said wireless relay network for execution by said medical device.

12. The system of claim 1, wherein said particular status provides a real-time authorization of use of the medical device by the patient based upon a pre-authorization record for the patient.

13. The system of claim 1, wherein:

one or more of the patient identification device, the medical device or the at least one relay module is capable of encrypting the patient identification information prior to transmitting the patient identification information to the remote monitoring device.

14. The system of claim 1, wherein:

one or more of the medical device or the at least one relay module are capable of encrypting the medical device identification information prior to transmitting the medical device identification information to the remote monitoring device.

15. The system of claim 1, wherein the patient identification device is coupled to the medical device, and the medical device is capable of receiving the patient identification information from the patient identification device and transmitting the patient identification information to the at least one relay module.

16. The system of claim 1, wherein the wireless relay network is a BLUETOOTH network.

17. The system of claim 15, wherein the medical device is capable of associating the patient identification information with the medical device information.

18. The system of claim 1, wherein said patient identification device further comprises a patient identification information reader for receiving the input indicative of patient identification information.

19. The system of claim 18, wherein the patient identification information reader is coupled to the medical device.

20. The system of claim 18, wherein the patient identification information reader comprises a barcode reader.

21. The system of claim 18, wherein the patient identification information reader comprises a radio frequency identification tag reader.

22. The system of claim 18, wherein the patient identification information reader comprises a device selected from the group consisting of fingerprint readers, retinal readers, vein-pattern scanners and cameras.

23. The system of claim 18, wherein the patient identification information reader comprises a device selected from the group consisting of smartphones, tablet computers, PDA'"'"'s and PCs.

24. The system of claim 5, wherein said memory of the at least one relay module is further capable of storing one or more of the received patient identification information or the received medical device identification information.

25. The system of claim 1, wherein the at least one relay module is further capable of transmitting the patient identification information and the medical device identification information in a single information block.

26. The system of claim 15, wherein the medical device further comprises a memory and is capable of storing the patient identification information received from the patient identification device in the memory of the medical device.

27. The system of claim 15, wherein the patient identification device is an integral component of or fixedly attached to the medical device.
