Abstract

A device for obtaining physiological information of a medical patient and wirelessly transmitting the obtained physiological information to a wireless receiver.

Claims

1. A wireless patient monitoring system comprising:

one or more optical sensors configured to obtain physiological information; and

a wireless monitor configured to receive the physiological information and to wirelessly transmit physiological data reflective of the physiological information to a bedside monitor,

wherein the wireless monitor comprises a removable battery, the removable battery including a data storage component.

2. The wireless patient monitoring system of claim 1, wherein the data storage component is configured to store information communicated from the bedside monitor.

3. The wireless patient monitoring system of claim 1, wherein the wireless monitor is configured to be coupled to an arm band attached to the patient.

4. The wireless patient monitoring system of claim 1, wherein the bedside monitor is configured to receive the removable battery.

5. The wireless patient monitoring system of claim 1, wherein the bedside monitor is configured to receive the wireless monitor.

6. The wireless patient monitoring device of claim 1, wherein the wireless transmitter is configured to transmit physiological data over a first wireless technology when a signal strength of the first wireless technology is sufficiently strong and transmit physiological data over a second wireless technology when the signal strength of the first wireless technology is sufficiently weak.

7. The wireless patient monitoring device of claim 1, wherein the wireless transmitter is configured to transmit physiological data over a first wireless technology when the wireless transmitter is within a pre-determined distance from the wireless receiver and transmit physiological data over a second wireless technology when the wireless transmitter is not within a pre-determined distance from the wireless receiver.

8. The wireless patient monitoring device of claim 1, wherein the removable battery includes a display.

9. The wireless patient monitoring device of claim 8, wherein the display is configured to activate when the wireless transmitter transmits physiological data over a first wireless technology and deactivate when the wireless transmitter transmits physiological data over a second wireless technology.

10. A method of wirelessly monitoring physiological information, the method comprising:

providing a battery including a data storage component;

connecting the battery to a bedside monitor;

transferring data from the bedside monitor to the data storage component;

connecting the battery to a wireless monitor;

obtaining physiological information from one or more optical sensors; and

transmitting physiological data reflective of the physiological information from the wireless monitor to the bedside monitor.

11. The method of claim 10, wherein the transferred data is a unique identifier.

12. The method of claim 10, wherein the transferred data is a password.

13. The method of claim 10, wherein the transferred data is channel information.

14. The method of claim 10, wherein transmitting physiological data from the wireless monitor to the bedside monitor comprises:

transmitting physiological data over a first wireless technology when the wireless monitor is within a pre-determined distance from the bedside monitor; and

transmitting physiological data over a second wireless technology when the wireless monitor is not within a pre-determined distance from the bedside monitor.

15. The method of claim 14, wherein the first wireless technology is Bluetooth or ZigBee.

16. The method of claim 14, wherein the second wireless technology is Wi-Fi or cellular telephony.

transmitting physiological data over the first wireless technology when a signal strength of the first wireless technology is sufficiently strong; and

transmitting physiological data over the second wireless technology when the signal strength of the first wireless technology is not sufficiently strong.

18. The method of claim 14, wherein transmitting physiological data over the second wireless technology activates a display on the battery.

19. The method of claim 17, wherein transmitting physiological data over the second wireless technology activates a display on the battery.

20. A system configured to wirelessly communicate physiological information including a battery, the battery comprising:

a housing;

a rechargeable electrical storage module; and

a memory module configured to store wireless communication information.

21. The system of claim 20, wherein the wireless communication information pairs a wireless monitor with a bedside monitor.
