Abstract

A monitoring system having a device on a person which can process and transmit signals from at least one biosensor and a receiver located close to the patient, which can receive these signals. The receiver, which may be a portable telephone, can process the signals and provide an indication of the parameter(s) being monitored and may also, or as an alternative, forward the received signals to a remote monitor. The monitoring system may further include a device for indicating when the transmitter is not receiving a signal from the transmitter and can also include a device so that when a parameter reaches a critical care level, a warning signal is given. The monitoring system is such that the person being monitored is effectively not limited to remaining within a required distance of a fixed part of the system.

Claims

1. A monitoring system, comprising:

at least one biosensor for generating a biometric signal from a measured parameter of a person;

a transmitter connected to the biosensor for transmitting the biometric signal using Bluetooth technology; and

a receiver not disposed in or coupled to a mobile telephone, for receiving the transmitted signal, displaying the biometric signal on a display device of the receiver, and wirelessly forwarding the signal to a remote monitor using General Packet Radio Service (GPRS).

2. The monitoring system of claim 1, wherein the display provides an indication of the parameter being measured, and the signal is displayed as an instantaneous FIGURE, a series of figures on a time basis, or a plot on a time basis of the parameter value.

3. The monitoring system of claim 1, wherein the measured parameter is the person'"'"'s heart rate, heart rhythm, blood pressure, temperature, respiration, blood oxygen level, blood carbon dioxide level, or blood pH level.

4. The monitoring system of claim 1, wherein the received signal is automatically forwarded to the remote monitor when the measured parameter exhibits a predetermined property.

5. The monitoring claim 1, wherein the received signal is periodically or selectively forwarded to the remote monitor.

6. The monitoring system of claim 1, wherein the received signal is continuously forwarded to the remote monitor.

7. The monitoring system of claim 1, wherein the receiver establishes a warning condition if it is not receiving the biometric signal.

8. The monitoring system of claim 1, wherein the receiver establishes a warning condition if the biometric signal exhibits a predetermined property.

9. The monitoring system of claim 8, wherein predetermined property is crossing a predetermined threshold.

10. The monitoring system of claim 8, wherein the predetermined property is related to a predetermined waveform.

11. The monitoring system of claim 8, wherein the warning condition automatically initiates an alarm at the receiver.

12. The monitoring system of claim 11, wherein the alarm is an audio or visual signal.

13. The monitoring system of claim 8, wherein the warning condition automatically initiates an audio or visual alarm at the remote monitor.

14. The monitoring system of claim 8, wherein the warning condition selectively initiates an audio or visual alarm at the remote monitor.

15. The monitoring system of claim 1, wherein the remote monitor initiates an audible or visual alarm if the biometric signal exhibits a predetermined property.

16. A monitoring system, comprising:

at least one biosensor for generating a biometric signal from a measured parameter of a person;

a transmitter connected to the biosensor for wirelessly transmitting the biometric signal over short range using Bluetooth technology;

a receiver not disposed in or coupled to a mobile telephone, located close to the person or receiving the transmitted biometric signal and displaying the biometric signal on a display device of the receiver;

and transmitting the biometric signal or a signal based on the biometric signal using General Packet Radio Service (GPRS); and

a monitor for receiving the biometric signal or a signal based on the biometric signal transmitted using General Packet Radio Service (GPRS) from the receiver.
