Abstract

The present invention discloses a wireless bio-signal monitoring system for monitoring a patient'"'"'s bio-signal. The system includes a bio-signal capture unit, an analysis unit, a wireless transmission unit, a receiver unit and a remote database. With a chaotic phase space difference algorithm, the consumption of system resources can be minimized and the power management of the monitoring system can be optimized. By capturing position coordinates of the receiver unit via the Internet, we can locate the position of the patient to provide medical treatments immediately in an emergency situation.

Claims

1. A wireless bio-signal monitoring system, comprising:

a bio-signal capture unit, for capturing at least one bio-signal of a patient;

an analysis unit, coupled to the bio-signal capture unit, for controlling a cycle of transmitting the bio-signal, analyzing the bio-signal by a chaotic phase space difference algorithm, and transmitting the bio-signal again when an abnormal condition occurs;

a wireless transmission unit, coupled to the analysis unit through a standard transmission interface, and capable of linking to a first network layer automatically; and

a receiver unit, being an access point on the first network layer, for receiving the bio-signal, transmitting the bio-signal to a remote database through a second network layer, and recording the bio-signal in the remote database.

2. The bio-signal monitoring system of claim 1, wherein the bio-signal capture unit, the analysis unit and the wireless transmission unit constitute a monitoring device.

3. The bio-signal monitoring system of claim 1, wherein the remote database captures position coordinates of the receiver unit for locating the position of the patient.

4. The bio-signal monitoring system of claim 1, wherein the bio-signal capture unit includes at least one bio-sensor and digitizes the captured bio-signal.

5. The bio-signal monitoring system of claim 4, wherein the bio-sensor is a body temperature sensor, a tri-axis accelerometer, a blood oxygen concentration sensor, a blood pressure sensor or a breath frequency sensor.

6. The bio-signal monitoring system of claim 1, wherein the wireless transmission unit further includes a wireless transmission interface for transmitting the bio-signal, and the wireless transmission interface is a Bluetooth, Zigbee, wireless fidelity (Wi-Fi) or worldwide interoperability for microwave access (WiMAX) interface.

7. The bio-signal monitoring system of claim 1, wherein the first network layer is a local area network (LAN), an Intranet or an Extranet.

8. The bio-signal monitoring system of claim 1, wherein the receiver unit is a network server, a personal computer (PC) or a personal digital assistant (PDA).

9. The bio-signal monitoring system of claim 1, wherein the second network layer is the Internet.

10. The bio-signal monitoring system of claim 1, wherein the remote database is situated at a medical unit for immediately notifying a medical professional for medical treatments if the bio-signal is an abnormal signal.
