Abstract

A physiological monitoring system includes a base station, the base station having a first wireless transceiver, and a patient monitor, the patient monitor comprising a data input, the data input configured to receive data regarding a physiological condition of a patient, the patient monitor further including a second wireless transceiver, the patient monitor capable of entering a wireless communications link with the base station through the first and second wireless transceivers, and of transmitting in substantially real-time the received data from the patient to the base station, the patient monitor further including a controller and a memory, the controller being configured to store in the memory the received data when the wireless communications link is interrupted.

2. The physiological monitoring system of claim 1 wherein the controller is further configured to end the storing of the received data and to send to the base station the stored received data from the memory of the patient monitor combined with new received data received through the data input, when the wireless communications link is reestablished.

3. The physiological monitoring system of claim 2 wherein the stored received data is combined with the new received data in an interleaved fashion.

4. The physiological monitoring system of claim 1 further comprising a central station coupled by a communications link to the base station.

5. The physiological monitoring system of claim 4 wherein the communications link is formed over a telephone network.

6. The physiological monitoring system of claim 4 wherein the base station further comprises a base station memory and a modem link.

7. The physiological monitoring system of claim 6 wherein the base station further comprises a base station controller, the base station controller configured to store in the base station memory received data from the patient monitor when the communications link with the central station is interrupted.

8. The physiological monitoring system of claim 7 wherein the base station controller is further configured to end the storing of the received data from the patient monitor and to send to the central station the stored received data from the base station memory combined with new received data received through the patient monitor, when the communications link is reestablished.

9. The physiological monitoring system of claim 8 wherein the stored received data is combined with the new received data from the patient monitor in an interleaved fashion.

10. The physiological monitoring system of claim 8 wherein the central station organizes the combined stored received data and the new received data into a substantially continuous, time ordered data record.

11. The physiological monitoring system of claim 7 wherein the communications link is interrupted when a telephone connected to the base station is used to make a telephone call.

12. The physiological monitoring system of claim 7 wherein the communications link is interrupted when a telephone connected to the base station receives an incoming telephone call.

13. The physiological monitoring system of claim 11 wherein the base station controller is further configured to end the storing of the received data from the patient monitor and to send to the central station the stored received data from the base station memory combined with new received data received through the patient monitor, when the telephone call ends.

14. The physiological monitoring system of claim 12 wherein the base station controller is further configured to end the storing of the received data from the patient monitor and to send to the central station the stored received data from the base station memory combined with new received data received through the patient monitor, when the telephone call ends.

15. A physiological monitoring system comprising:

a base station, the base station comprising a first wireless transceiver, a base station controller, and a base station memory; and

a patient monitor, the patient monitor comprising a data input, the data input configured to receive data regarding a physiological condition of a patient, the patient monitor further comprising a second wireless transceiver, the patient monitor capable of entering a wireless communications link with the base station through the first and second wireless transceivers, and of transmitting in substantially real-time the received data from the patient to the base station, the patient monitor further comprising a controller and a memory, the controller being configured to store in the memory the received data when the wireless communications link is interrupted, and to end the storing of the received data and to send to the base station the stored received data from the memory of the patient monitor combined with new received data received through the data input, when the wireless communications link is reestablished;

a central station coupled by a communications link to the base station, the base station controller configured to store in the base station memory received data from the patient monitor when the communications link with the central station is interrupted, and to end the storing of the received data from the patient monitor and to send to the central station the stored received data from the base station memory combined with new received data received through the patient monitor, when the communications link is reestablished, wherein the central station organizes the combined stored received data and the new received data into a substantially continuous, time ordered data record.

16. A method for physiological monitoring comprising:

receiving, at a patient monitor, data regarding a physiological condition of a patient,

transmitting in substantially real-time the received data from the patient to a base station via a wireless communications link, and

storing in memory of the patient monitor the received data when the wireless communications link is interrupted.

17. The method of claim 16 further comprising, when the wireless communications link is reestablished, ending the storing of the received data, and sending to the base station from the patient monitor memory the stored received data combined with new received data.

18. The method of claim 17 wherein the stored received data is combined with the new received data in an interleaved fashion.

19. The method of claim 16 further comprising sending the received data from the base station to a central station via a communications link.

20. The method of claim 19 wherein the communications link is formed over a telephone network.

21. The method of claim 19 further comprising storing in a memory at the base station received data from the patient monitor when the communications link with the central station is interrupted.

22. The method of claim 21 further comprising, when the communications link is reestablished, ending the storing of the received data from the patient monitor and sending to the central station the stored received data from the base station memory combined with new received data received through the patient monitor.

23. The method of claim 22 wherein the stored received data is combined with the new received data from the patient monitor in an interleaved fashion.
